Answer: 512 cm³
Explanation: Since the length, width, and height of a cube are all equal,
we can find the volume of a cube by multiplying side × side × side.
So we can find the volume of a cube using the formula v = s³.
In the cube in this problem, we have a side length of 8 cm.
So plugging into the formula, we have (8 cm)³
or (8 cm)(8 cm)(8 cm), which is 512 cm³.
So the volume of the cube is 512 cm³.
Answer:
5y + 7
Step-by-step explanation:
Given:
Seeds planted in one garden = y vegetable seeds
Seeds planted in another garden = 4y + 7 vegetable seeds
To Find:
The number of seeds Val is going to plant = ?
Solution:
Let the total number of seeds that Val is going to plant be x.
Then
x = number of seeds planted in garden one + number of seeds planted in the other garden
Now substitute the values, we get
x = y + (4y+7)
x = 5y + 7
The answer x = 11 is correct for problem 4. Nice work.
Use this x value to find the answer in problem 5. From problem 4, we're told that Romeo runs at a speed of 5 m/s. If he runs for x = 11 seconds,then he runs a total distance of:
5*x =(5 m/s)*(x meters) = (5 m/s)*(11 seconds) = 5*11 = 55 meters
The answer to problem five is 55 meters
359 is the correct answer for the English one I think
