Use the diagram of the equilateral triangle shown below to answer the following questions. Show the work that leads to your answers. a. What is the perimeter of the triangle? b. What is the height, ℎ mm, of the equilateral triangle? Write an exact answer using a square root and an approximate answer rounded to the tenths place.

Answers

Answer:

Perimeter is 12mm, height is $2\sqrt3$mm in simplest radical form, and 3.5mm in approximate decimal form.

Step-by-step explanation:

The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.

For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem ($a^2+b^2=c^2$) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.

I've enclosed an attachment for that.

Determine if the following side lengths can create a triangle:
5, 7, 13
A. Yes
B. No

Answers

Answer:

Step-by-step explanation:

In order for three sides to make a triangle, if any two sides are added together, their sum should be greater than the third side:

=> 5 + 7 = 12 < 13 (DOES NOT check off the rule)

=> 7 + 13 = 20 > 5 (Checks off the rule)

=> 5 + 13 = 18 > 7 (Checks off the rule)

As shown, even though 2 of the statements check off the rule the third one does not, this means that the sides don't make a triangle.

Hope this helps!

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide

Answers

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.

A little help here? And can anyone explain this?

Answers

Answer:

Step-by-step explanation:

According to the dot plot,

3 students spend 0.5 minutes brushing their teeth.

2 students spend 1.5 minutes brushing their teeth.

1 student spends 2.5 minutes brushing their teeth.

2 students spend 3.5 minutes brushing their teeth.

1 students spend 4 minutes brushing their teeth.

So, the number set will be: {0.5, 0.5, 0.5, 1.5, 1.5, 2.5, 3.5, 3.5, 4}

Median: The middle number in a set that is ordered from least to greatest.

In this example, the median is 1.5

Mean: The sum of all values divided by the number of values.

In this set there are 9 values so we’ll divide the sum by 9

In this example, the mean would be:

(0.5 + 0.5 + 0.5 + 1.5 + 1.5 + 2.5 + 3.5 + 3.5 + 4) ÷ 9

18 ÷ 9 = 2

If we compare the mean to the median we can see that the mean is greater because 2 > 1.5

The right answer is D

Mrs. Jones wants to paint the back wall of her classroom light blue. If the dimensions of the wall is 20 feet by 12 feet, how much paint will she need to paint her classroom wall? Round to the nearest tenth if necessary.

Answers

Answer:

The total area of the back classroom wall is (20ft x 12ft) = 240ft²

The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².

Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.

Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

The answer to the question is 0.6 gallons

A soccer player practices kicking the ball into the goal from halfway down the soccer field. The time it takes for the ball to get to the goal from the time it is kicked averages about three seconds. The soccer field is 90 meters long. The player wants to know the average velocity of the ball. Is there enough information to calculate this?

A No, only average speed can be calculated from the distance of 45 meters and the time of three seconds.

B Yes, displacement is 45 meters, elapsed time is three seconds, and the direction is toward the goal.

C No, only average speed can be calculated from the distance of 90 meters and the time of three seconds.

D Yes, displacement is 90 meters, elapsed time is three seconds, and the direction is toward the goal.

Which of the following is closest to the diagonal length between A and B?

Answers

ok this is going to have a long explanation

use the pythagorean theorem to solve this (a2+b2 = c2)

imagine the line as the hypotenuse of a triangle. we already have a2, which is 12, but we don’t have b2 or c2. c2 is the diagonal

to find b2, apply the pythagorean theorem to the 8in and 6in

8^2 + 6^2 = c^2

reducing this makes it 64+36=c^2

add the left side together to get 100=c^2

square root both sides to get 10=c

now we know that the bottom of the “triangle” is 10

now, to find the length of the line, apply the 12 in and 10in we just found into the pythagorean theorem.

12^2+10^2=c^2

reduce it to get 144+100=c^2

add to get 244=c^2

square root both sides to get 15.62=c

the length of the diagonal between A and B should be around 15.62

hope this helped!!

What is the correct expanded form and value of (One-fifth) Superscript 4?
One-fifth + one-fifth + one-fifth + one-fifth = StartFraction 4 Over 5 EndFraction
One-fifth times one-fifth times one-fifth times one-fifth = StartFraction 1 Over 625 EndFraction
StartFraction 1 + 1 + 1 + 1 Over 5 times 4 EndFraction = StartFraction 4 Over 20 EndFraction
One-fifth times 4 = StartFraction 4 Over 5 EndFraction

Answers

Answer:

One-fifth times one-fifth times one-fifth times one-fifth = StartFraction 1 Over 625 EndFraction

Step-by-step explanation:

1/5^4 = 1/5 * 1/5 * 1/5 *1/5 = 1/625

The expanded form of (One-fifth)⁴ is "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction," and its value is "StartFraction 1 Over 625 EndFraction."

The expanded form of (One-fifth)⁴ can be derived by multiplying (1/5) four times. Each multiplication represents multiplying by one-fifth, resulting in "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction." This can be further simplified as "StartFraction 1 Over 625 EndFraction" by multiplying the numerators and the denominators separately.

In mathematical terms, when we raise one-fifth to the power of 4, we are essentially multiplying one-fifth by itself four times. Thus, (One-fifth)⁴ is equal to "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction."

Evaluating this expression yields the value "StartFraction 1 Over 625 EndFraction" since multiplying the numerators (1 * 1 * 1 * 1) and the denominators (5 * 5 * 5 * 5) results in 1 and 625, respectively.

Mathematical representation: $\frac{1}{5}^4= \frac{1}{5} * \frac{1}{5} * \frac{1}{5} * \frac{1}{5}$

The countries population in 1991 was 231 million . In 1999 it’s was 233 million. estimate the population in 2003 used The exponential growth formula. Round your answer to the nearest million

Answers

Answer:

The population in 2003 was 234 million

Step-by-step explanation:

In order to calculate the population in 2003 we would have to use the The exponential growth formula as follows:

p(y)=ir^t

According to the given data:

p(y)=233 million

i=231 million

t =1999-1991

Therefore, 233 million=231 million r^(1999-1991)

(233 million/231 million)^(1/8)=r

p(y)=231 million(233 million/231 million)^((y-1991)/8)

Therefore, in 2003 p(2003)=231 million(233 million/231 million)^((2003-1991)/8)

p(2003)=231 million(233 million/231 million)^(1.5)

p(2003)=234 million

The population in 2003 was 234 million

HURRY PLEASEQ. 25This passage is taken from a letter written by a father to his son.DEAR BOY, Bath, October the 4th, O. S. 1746.Though I employ so much of my time in writing to you, I confess I have often my doubts whether it is to any purpose. I know how unwelcome advice generally is; I know that those who want it most like it and follow it least; and I know, too, that the advice of parents, more particularly, is ascribed to the moroseness, the imperiousness, or the garrulity of old age. But then, on the other hand, I flatter myself, that as your own reason (though too young as yet to suggest much to you of itself) is, however, strong enough to enable you both to judge of and receive plain truths: I flatter myself, I say, that your own reason, young as it is, must tell you, that I can have no interest but yours in the advice I give you; and that, consequently, you will at least weigh and consider it well: in which case, some of it will, I hope, have its effect. Do not think that I mean to dictate as a parent; I only mean to advise as a friend, and an indulgent one too: and do not apprehend that I mean to check your pleasures; of which, on the contrary, I only desire to be the guide, not the censor. Let my experience supply your want of it, and clear your way in the progress of your youth of those thorns and briers which scratched and disfigured me in the course of mine. I do not, therefore, so much as hint to you how absolutely dependent you are upon me; that you neither have nor can have a shilling in the world but from me; and that, as I have no womanish weakness for your person, your merit must and will be the only measure of my kindness. I say, I do not hint these things to you, because I am convinced that you will act right upon more noble and generous principles; I mean, for the sake of doing right, and out of affection and gratitude to me.I have so often recommended to you attention and application to whatever you learn, that I do not mention them now as duties, but I point them out to you as conducive, nay, absolutely necessary, to your pleasures; for can there be a greater pleasure than to be universally allowed to excel those of one's own age and manner of life? And, consequently, can there be anything more mortifying than to be excelled by them? In this latter case, your shame and regret must be greater than anybody's, because everybody knows the uncommon care which has been taken of your education, and the opportunities you have had of knowing more than others of your age. I do not confine the application which I recommend, singly to the view and emulation of excelling others (though that is a very sensible pleasure and a very I warrantable pride); but I mean likewise to excel in the thing itself: for, in my mind, one may as well not know a thing at all, as know it but imperfectly.
