The ratio of the angle measures of a triangle is 1:2:2. What is the value of the smallest angle? 180° 90° 72° 36°
Answers
Answer:
36 degrees.
Step-by-step explanation:
All the angles in a triangle add up to be 180 degrees. Since the ratio is 1:2:2, you can say that the angles are x, 2x, and 2x.
x + 2x + 2x = 180
5x = 180
x = 180 / 5
x = 36
Since the smallest part of the ratio is 1, the smallest angle is 36 degrees.

-2.25 + 0.4x = -2.8
Solve as a simplified mixed number and as a decimal
Answers
Answer:
-1 3/8 and -1.375
Step-by-step explanation:
To solve for x in the equation -2.25 + 0.4x = -2.8, we can start by isolating the variable term (0.4x) on one side of the equation:
-2.25 + 0.4x = -2.8
0.4x = -2.8 + 2.25
0.4x = -0.55
Next, we can divide both sides by 0.4 to solve for x:
x = -0.55 / 0.4
x = -1.375
As a mixed number, -1.375 can be written as:
-1 3/8
As a decimal, -1.375 is already in decimal form.

B-1.053
C-1.087
D-1.12
Answers
The mean deviation of the number of pets Ramiro surveyed as shown in the table attached below is: D. 1.12
To find the mean deviation of the number of pets, the following steps would be taken:
Find the mean, which is sum of each frequency and score (fx) divided by the total number of pets. \(\mathbf{(\frac{\sum fx}{n} )}\)Subtract the mean from each score, \(\mathbf{( x - \bar x)}\)Sum the deviations together and divide by total number of pets.The formula for the mean deviation is given as: \(\mathbf{\frac{\sum f* |x - \bar x|}{n} }\)Mean deviation as solved in the table attached in the image below would be:
\(\mathbf{\frac{33.6}{30} = 1.12}\)
Therefore, the mean deviation of the number of pets Ramiro surveyed as shown in the table attached below is: D. 1.12

A department store offered a 15% discount off the regular price of a shirt. The amount of the discount is $3. What is the regular price of the shirt?
Answers
Answer: $3.53
Step-by-step explanation: 15 percent off can be thought of as 85% of the original value because 100-15 is 85. this means that if x is the value of the original shirt, .85x=3
divide by .85
x=3.5294
which is about $3.53
Answer:
You will pay $12 for a item with original price of $15 when discounted 20%. In this example, if you buy an item at $15 with 20% discount, you will pay 15 - 3 = 12 dollars.

Show that AC and BD bisect each other if A(–3, –5), B(2, –3), C(3, 5), and D(–2, 3). Find AC and BD
Answers
Answer:
Step-by-step explanation:
midpoint of AC=((-3+3)/2,(-5+5)/2)=(0,0)
midpoint of BD=((2-2)/0,(-3+3)/2)=(0,0)
coordinates of midpoint of AC and BD are same.
∴ AC and BD bisect each other.
\(AC=\sqrt{(3-(-3))^2+(5-(-5))^2 } =\sqrt{6^2+10^2} =\sqrt{136} =2\sqrt{39} \\BD=\sqrt{((-2-2)^2+(3-(-3))^2} =\sqrt{16+36} =\sqrt{52} =2\sqrt{13}\)
Midpoint of AC and BD is ( 0, 0 ), so both bisects each other.
The value of AC = 2 √39 and BD = 2 √13
Here, points given as,
A(–3, –5), B(2, –3), C(3, 5), and D(–2, 3).
We have to find, AC and BD.
What is distance between two points?
Distance between two points \(P(x_{1} ,y_{1} )\) and \(Q(x_{2} ,y_{2} )\) is given by:
\(d(P, Q) = \sqrt{(x_{2}- x_{1} )^2 +(y_{2}- y_{1} )^2 }\)
Now,
Midpoint of AC = \((\frac{-3+3}{2} ), (\frac{-5+5}{2} ) = ( 0, 0 )\)
Midpoint of BD = \((\frac{-2+2}{2} ), (\frac{-3+3}{2} ) = ( 0, 0 )\)
Hence, Both AC and BD bisects each other.
And, Distance between A and C is,
AC = \(\sqrt{(3 - (-3))^2 +(5 - (-5))^2 } = \sqrt{36 + 100} = \sqrt{136} = 2\sqrt{39}\)
Distance between B and D is,
BD = \(\sqrt{( -2 -2))^2 +(3 - (-3))^2 } = \sqrt{16 + 36} = \sqrt{52} = 2\sqrt{13\)

Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128

What is the approximate perimeter of the figure? Use 3.14 for pi.
Answers
Answer:
34,28 ft
Step-by-step explanation:
This figure is formed from a rectangle and a semi-circle
Opposite sides of a rectangle are equal
This figure's perimeter is the sum of all side lengths:
2 sides of 12 ft
1 side of 4 ft
Half of the circumference
d (diameter) = 4 ft
r (radius) = 0,5 × 4 = 2 ft
First, we have to find the half of the circumference (C):
\(0.5c = (2\pi \times r\))/2
\(0.5c = (2 \times 3.14 \times 2)/2 = 6,28\)
Now, we can find the perimeter of the given figure:
P = 6,28 + 12 + 12 + 4 = 34,28 ft

A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9. When comparing the shape of the two sets of data, what conclusion can someone draw? The students tend to have fewer siblings than the teachers. The teachers tend to have fewer siblings than the students. Both the students and the teachers have a wide range of siblings. Both sets of data have the same shape. the answer is- a. The students tend to have fewer siblings than the teachers.
Answers
Answer:
A. The students tend to have fewer siblings than the teachers.
Step-by-step explanation:
First we need to draw the dot plots correctly. If you count both sides they have 20 each.
Now, clearly none have fewer nobody here yet has more or less but going on to the next step.
Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14. And so on.
On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.
So the answer is A. The students tend to have fewer siblings than the teachers.

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

During a 20% off sale, the sale price of a microwave was $60. The sale has expired but Kristen has a coupon good for 15% off the regular price of any one item. How much will Kristen pay for the microwave before tax? Round to the nearest cent.
Answers
Answer:
it would take 9 dollar OFF!! so subtracted by 60 your welcome!!
(its 51 just saying.)
Step-by-step explanation:
x - 0.2x = 60
Simplifying the left side, we get:
0.8x = 60
Dividing both sides by 0.8, we get:
x = 75
So the regular price of the microwave is $75. Now, we can use Kristen's coupon to find the price she will pay:
Regular price = $75
Discount from coupon = 15%
Amount of discount = 0.15 x $75 = $11.25
Subtracting the discount from the regular price, we get:
Price after coupon = $75 - $11.25 = $63.75
Therefore, Kristen will pay $63.75 for the microwave before tax.
