Answer:

7 in

Step-by-step explanation:

volume of a rectangular prism = width x height x length

width x length = area of the base

the sea shell box

200 = width x length x 5

width x length = 200/5 = 40cm^2

rock box

280 = 40in^2 x height

height = 280/40 = 7 in

The lengths of the sides of a triangle are in the ratio of 6:6:5. The perimeter of the triangle
Oliga [24]

Hello!

Answer:

12 cm, 12 cm, 10 cm.

Step-by-step explanation:

Given:

Perimeter, or P = 34 cm

Ratio of sides = 6 : 6 : 5

To find the length of each side, we can use a variable in the ratio to find the perimeter:

34 = 6x + 6x + 5x

Combine like terms:

34 = 17x

Solve for x:

34/17 = 17x/17; x = 2

Plug in this value of "x" into each expression for the side-lengths:

6(2) = 12 cm

6(2) = 12 cm

5(2) = 10 cm

Therefore, the lengths of each side of the triangle are 12 cm, 12 cm, 10 cm.

Hope this helped you! :)

Plot the reflection of point A across the x-axis. What are the coordinates of the reflection of point A across the x-axis? What
UNO [17]
You got the dot on the right spot, the coordinates are (1.5,2.5) because you reflected across the x axis so the y coordinate changed. The distance between them are 5, because you move half of a unit two times which equals 1 whole unit and 4 whole units. 4+1=5
