Answer:

C. (12.5 , 23.75)

Step-by-step explanation:

Answer #1:

X= 75

Y= 15

Step-by-step explanation: The first equation is x+y=90 and then your next equation is x=5y. After you have those two equation you sub them in 5y+y=90 and once you solve for y you solve for x.

Answer:

Think you alredy said the answer.

Step-by-step explanation:

Answer:

6 511 104 in³

Step-by-step explanation:

Since we have 1 crate and 8 boxes fit into one crate.

So, volume of one crate, V' = 8 × volume of 1 box, V

Since the box is a rectangular prism of sides 2512 inches high, 18 inches long, and 18 inches wide, its volume, V = lwh where l = length of prism, h = height of prism and w = width of prism.

So, V = lwh = 18 in × 18 in × 2512 in = 813 888 in³

So, V' = 8 × 813 888 in³ = 6 511 104 in³

So, the minimum volume of the crate is 6 511 104 in³

Answer:

A= 120  

b=200 (if the number on the bottom is a 4 thats cut out)

Step-by-step explanation:

for volume u just multiply the 3 numbers it gives u for the models like for example in the picture u do

6*4*5 in no specific order

if its a triangle and volume or area u do that but at the end divide by 2 in area

Step-by-step explanation:

Answer:

y' = a(x'- ((h-15)/20))² + -(k-30)

Step-by-step explanation:

Vertex: (h,k)

horizontally translated 15 units left: (h-15 , k)

stretch by a factor of 20: ((h-15)/20 , k)

vertically translated down 30 units: ((h-15)/20 , k-30)

reflected in the x axis: ((h-15)/20 , -(k-30))

Vertex' (h' , k'): ((h-15)/20 , -(k-30))

Equation: y' = a(x'-h')² + k'

y' = a(x'- ((h-15)/20))² + -(k-30)

Answer:

510 is the area

Step-by-step explanation:

btw the next time you need help with an area multiply the length (the long side of the shape) times the width (the short side of the shape) if you feel like the answer is wrong when you multiply it just use a calculator and you get your answer

The radius of the circle is around 31.65 cm. Choice B

The formula C = 2πr , where C is the circle's circumference and r is its radius, yields the circumference of a circle. In this illustration, the circle's circumference is given as 198 cm

C = 2πr

The formula to calculate the radius can be revised as follows:

r = C / (2π)

r = 198 / (2 * 3.14)

To perform the calculation, divide the numbers:

r ≈ 198 / 6.28

r ≈ 31.65

The circle's estimated radius is 31.65 centimetres as a result.

So, rounded to the closest hundredth, the estimated radius of the circle with a circumference of 198 centimetres is 31.65 centimetres.

The closest option to 31.65 in the list of possible answers is B. 31.53. It's crucial to keep in mind that choosing 3.14 as an approximation for involves some mistake and that the precise radius number might change slightly.

When rounded to the next hundredth, the radius is 31.65. This result can be compared to the other solutions to show that:

B. 31.53.

There are 5 sixth graders over a  total of 5+8+9 = 22 students. Therefore the percent of sixth graders would be:

5/22 * 100 ≈ 22.72 %

Answer:

Its A. have a good day

Step-by-step explanation:

Answer:

using Pythagoras theorem 11/2 is the largest side so let a=9/10 b=11/5 c=11/2

a²+b²=c²

(9/10)²+(11/5)²=(11/2)²

81/100+121/25=121/4

lcm of 25 and 100 =100

(81+484)/100=121/4

565/100=121/4

113/20=121/4

since they are not equal therefore it's not a right angle triangle

Answer:

1.7

Step-by-step explanation:

To find the distance between two coordinates, use the formula [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex].

y2 = 4, y1 = 9, x2 = -1, x1 = 2

Insert the values into the equation:

[tex]\frac{4-9}{-1-2}[/tex]

Simplify:

[tex]\frac{4-9}{-1-2}= \frac{-5}{-3}=\frac{5}{3}[/tex][tex]\frac{}{} =1.7[/tex]

The distance between (2, 9) and (-1, 4), rounded to the nearest 10th, is 1.7.
