Chandra had scores of 100, 70, and 85 on three of her five tests. She cannot remember her two other scores, which were both the same. She does remember that the mean of the five scores is 75. Which statement below explains how to find the two missing scores?


Add the sum of the three test scores to the product of 75 and 5.

Subtract the sum of the three test scores from the product of 75 and 5.

Add the sum of the three test scores to the product of 75 and 5, and then double the result.

Subtract the sum of the three test scores from the product of 75 and 5, and then divide the result by 2.

Answer:

5625π cm²

Step-by-step explanation:

Radius = 150 / 2 = 75 cm

Area = πr² = π(75)² = 5625π cm²

Answer: 17662.5 (I used 3.14 instead of the regular pi but if you need to use pi the answer would be 17671.4587)

Step-by-step explanation:

First, you grab the diameter then divide that by 2 (that gives you the radius of the circle) Then, multiple 75² * 3.14 (or pi) to give you the answer!

Hope this helps! Good luck!

Answer:

0

Step-by-step explanation:

for which m is the slope, b is the y-intercept, x is any x value and y is any y value. By looking at the equation of the trend line, you can determine the y-intercept. For example, if the equation of the trend line is y=2x+5, the y-intercept is 5. You would receive this same answer if you let x = 0.

Josh was driving faster

Step-by-step explanation:

Josh was going faster becuase 320 divided by 4 is 80

and 225 divided by 3 is 75.

In conclusion Josh was going faster by 5mph.

Answer:

Step-by-step explanation:

4.

a)

P = 2width + 2length

8x = 2x + 2 length; 8x-2x = 2 length; 6x=2 length

length = 3x

b)

sides= 1/4 of 3x = 3x/4

perimeter of square = 4* side = 4*3x/4 = 3x

c)

x= 4

P rectangle =8x= 8*4= 32

P square = 3x = 3*4 = 12

32-12 = 20 cm greater is the P rectangle than P of square

d)

A rectangle = 2x*x = 2*4*4 = 32

A square =(3x/4)² = (3*4/4)² = 9

32-9 = 23 cm² greater is the A rectangle than A of square

4Comic+1 Nonfiction

4comic = 8y so 1 comic = 2y

1 nonfiction = (3+7y)+ 2y

a)

1 nonfiction = 7y+2y+3 = 9y+3

b)

total= 8y+9y+3 = 17y+3

if y=4

total = 17*4 +3  = $71

Answer: y=2x+2

Step-by-step explanation:

Rule as an expression: 2x+11-8

Simplify: 2x+2

Rewrite as an equation with x (input) and y (output): y=2x+2

Answer:

Question 10.

angle 1 = 137°

angle 2 = 43°

angle 3 = 137°

reasoning - vertically opposite angles are equal, and angles on a point total to 360 degrees

Question 11.

a) Vertical: I dont know sorry :(

b) Complementary: ∠c and ∠b

c) Suplementary: ∠c and ∠d

d) All adjacent: I dont know sorry :(

e) Find values of all angles, if angle c is 30°: ∠a = 90°, ∠b = 60°, ∠c = 30°, ∠d = 150°, ∠e = 30°

hope this helps :)

Answer:

the two balls are yellow and green, in either order.

Step-by-step explanation:

P(Y) = 5/10 = 1/2

P(R) = 3/10

P(G) = 2/10

Since the only combination that makes a product of 1/10, so

P(Y)*P(G) = (5//10) * (2/10) = 10/100 = 1/10

So the two balls are yellow and green, in either order.

Answer:

C

Step-by-step explanation:

hi there user! Looks like your looking for help, so Mizuki came here to help you!

the answer is:

m is 2/3

The whole work I did:

m + 4 ÷ 3 = 2

m + 4/3 = 2

m + 4/3 - 4/3 = 2 - 4/3

m = 6/3 - 4/3

m = 2/3

Anyways hope this helped! qwq

M is -41. If you add 43 to -41, your result will be 2. A number line would help you, too.

Answer:

Aqua Town 6 + 1x = y

Wet World 3+ 2x = y

Step-by-step explanation:

Answer:

27-degrees

Step-by-step explanation:

these are vertical angles which are equal to each other *congruent

39 + k = 66 --> *subtract 39 from both sides*

k = 27

Answer:

27°

Step-by-step explanation:

Remember the angle opposite of another angle in two straight lines are equal

So 66=39+k

Then put k by itself by subtracting 39 from both sides

66-39=k

k=27°

Step-by-step explanation:

Answer:

y-intercept: -3.

Slope:7/5

Step-by-step explanation: Y-intercept: The line crosses the y-axis at y=-3.

Slope: If you start from the point on the y-axis, -3, and count up 7 units, you reach 4 and then count right 5 units to reach a part of the line which touches a point. You go up 7 and go right 5 units. Therefore, the slope is 7/5. You go up, or rise, 7 units, and go right, or run, 5 units.
