If Amber pays $55 for a pair of shoes, what would the discount be if the original price for Amber's shoes is $72.00?

Answer: 4/5 = 180/b; b = 225 boys

Answer:

Given that there are 4 boys for every 5 girls, we can set up the following proportion:

4/5 = x/180

where x is the number of boys.

To solve for x, we can cross-multiply:

5x = 4 * 180

5x = 720

x = 144

Therefore, there are 144 boys.

been there ages ago, so we know best.

Answer:

At least 714 numbers of widgets must be sold per day to make a profit.

Given fixed operating cost = $2,500 per day cost of widget =$ 1.50

widget sells  =$ 5.00

Cost function = C(X)=1.50x+2500

Revenue function = R(X)=5 x

At Break Even point R (X) = C (X)5

X= 1.50X+2003.5

X =2500X =714

Hence to reach break even point or make profit 714 no to be sold. R(714)= 3571.

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Question 1: P = 35 degrees

It is given to us that angles N and P are complementary.

Complementary angles means the sum of the angles = 90 degrees.

Because angles N and M are supplementary, meaning they = 180 degrees, you can subtract angle M from 180.

180 - M = N

180 - 125 = 55

N = 55 degrees

Now that we know N = 55 degrees, we subtract that from 90 degrees to find P for N + P = 90 degrees, so if we subtract 55 from 90 we will get the value of angle P.

90 - N = P

90 - 55 = 35

P = 35 degrees!

Question 2: Option 4

We are trying to figure out which angles are congruent to one another.

We can rule out option one, for angles 1 & 4 are supplementary meaning their sum = 180 degrees.

The same applies for options 2 & 3, leaving us with the correct answer, option 4. We can make sure this is true because angles 3 & 5 are alternate interior angles, and alternate interior angles of parallel lines are congruent.

Question 3: x = 5

The three different angles add up to 180 because they are a straight angle.

First, we need to find out what 9 and 10 are equal to.

To do so, we can subtract 85 from 180.

180 - 85 = 9x + 10x

9x + 10x = 95

Now that we have an equation, we can simplify to find the value of x.

9x + 10 = 95

19x = 95

Divide by 19 on each side to isolate the variable x

x = 5

Hope this helps!

Answer: x=1.5

Step-by-step explanation:

The input value for which f(x) = g(x) is true is x= 1.5.

In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

We have,

The intersection both functions is the point when f(x)=g(x).

As, the point of intersection both graphs is (5, 2)

Here for the input value of x= 1.5

f(1.5)= 2

g(1.5)= 2.

So, f(1.5)= g(1.5)= 2

Sorry if Im wrong

Answer:

A, C

Step-by-step explanation:

If it is inversely proportional then y = k/x

Let's try one by one for the options. (im replacing y and x in the equation and finding k to see if k is the same all throughout)

A.

6 = k/1 (k=6)

3 = k/2 (k=6)

2 = k/3 (k=6)

1.5 = k/4 (k=6)

Yes! It's the same everywhere so this is correct!

B.

7.5 = k/2 (k=15)

5 = k/3 (k=15)

3 = k/5 (k=15)

2 = k/7 (k=14)

For the last one k is not the same so nope. It is wrong.

C.

24 = k/1 (k=24)

8 = k/3 (k=24)

k = 6×4 = 24

k = 24×1 = 24

This is correct too.

D.

k = 0.1×200 = 20

k = 0.3×40 = 12

k = 0.8 × 25 = 20

We can already see that k is not the same everywhere.

Only A and C, x and y are inversely proportional for all of the values

D. an = 4.2n-1

Step-by-step explanation: First, calculate the ratios between each term and the one that precedes it.

8/4=2 ....16/8=2...32/16= 2...

Upon comparing the ratios we see the ratio between each term and the one that precedes it is 2 for all the terms, the sequence is geometric, and the common ratio is r = 2.

Now, we simply need to find the other unknown values in the equation, a1= the first term of the sequence which is 4, Therefore a1=4

Looking at the options provided we see that no further missing quantity can further be found so we put this in the equation provided for a geometric sequence.

We get 4. 2n-1, which is our answer.

Answer:

Ribeye (ea) = $18.54

Salmon (ea) = $9.78

Step-by-step explanation:

x is the price for each ribeye steak

y is the price for each grilled salmon

15x + 28y  = $551.97 (a)

24x + 14y = $581.91 (b) -----(x2)------> 48x + 28y = 1163.82 (c)

Subtract c with a

48x + 28y = 1163.82 (c)

15x + 28y  = $551.97 (a)

===================  -

33x           = 611.85

x = 18.54

Put the value of x into a

15 · 18.54 + 28y = 551.97

278.1 +28y = 551.97

28y = 273.87

y = 9.78

In conclusion, the price of 1 ribeye is $18.54, and the price of 1 salmon is $9.78.

Answer:

Therefore, the residents of Somerville used their cell phones for approximately 8,930 minutes last year.

Step-by-step explanation:

To find out how many minutes the residents of Somerville used their cell phones last year, we can use the information given that this year's cell phone usage is 30% more than last year's.

Let's assume the cell phone usage last year was represented by the variable "x" (in minutes).

According to the information given, this year's cell phone usage is 30% more than last year's, so we can express this as:

x + 0.3x = 11609

Combining like terms, we have:

1.3x = 11609

To isolate the variable, we divide both sides of the equation by 1.3:

x = 11609 / 1.3

Simplifying the calculation, we find:

x ≈ 8930

Answer: We can add the fractions 2/9 and 5/9 together by adding the numerators and keeping the same denominator.

Step-by-step explanation:

if the denominators are different, we can't combine them because the pieces are not the same size. In the first problem, both the denominators are 9 so they have a common denominator. We can add the fractions 2/9 and 5/9 together by adding the numerators and keeping the same denominator.

Answer:

  492

Step-by-step explanation:

You want the value of (25c+48a) when c=12 and a=4.

Put the numbers in place of the corresponding variable and do the arithmetic. A calculator can help you out, if needed.

  25c +48a = 25·12 +48·4 = 300 +192 = 492

__

Additional comment

There are some mental math tricks that can help you do this in your head:

  25 = 100/4, so 25·12 = (100/4)·12 = 100·(12/4) = 100·3 = 300

  4 = 2·2, so 48·4 = (48·2)·2 = 96·2 = 192

Doubling or halving a number is generally pretty easy, so multiplication or division by 2, 4, or 8 can be accomplished by repeatedly multiplying or dividing by 2.

The sum of angles in a triangle is always equal to  180 degrees

Add:

65 + 51 + x + 73 = 180

x + 189 = 180

x = -9      That is fine that x is "-9" because this would just mean that the angle "x+73" is just bigger than it is supposed to be.

Proof:

65 + 51 - 9 + 73 = 180

Therefore, x = -9

Answer:

x = -9

Step-by-step explanation:

Notes to remember:

A triangle's angles will always add up to 180°

--------------------------------------------------------------------

As the image shows, we have two labeled angles. A 51° angle and a 65° angle.

Here's how you want to set up your equation:

180° = 51 + 65 + x + 73

(Rearrange)

180° = 51 + 65 + 73 + x

Add 51, 65, and 73

180° = 189 + x

Subtract 189 from both sides, to isolate x.

-9° = x

ALWAYS PLUG IN (the number that comes from the variable) TO CHECK YOUR WORK!

180° = 51 + 65 - 9 + 73

Hello there!

First things first, place the 2 on the y-axis. 2 is your "y" intercept.

Rule of thumb:  if there is a constant(single number) alone and without any variable next to it, it's going to be your y-intercept.

Next we need to count up three units from the y-intercept and over four units.

Overall:

The 2 should be plotted on the y-axis.

The new coordinate should be (5,4)
