x = 20
Step-by-step explanation:
x = 50/2.5 = 2.5x = 50
Answer:
<h2> 40in^3</h2>
Step-by-step explanation:
Step one:
given data
dimension of the box
lengh= 5 in
width= 2 in
height =4 in
Required
the volume of the box
the expression for the volume is
V=L*W*H
V=5*2*4
V=40 in^3
Hence the volume of sand the box can take is 40in^3
Answer:
The area of the base is = 5.2 cm²
Step-by-step explanation:
<em>First, we need to know the formula to calculate volume:</em>
<em>if we change to our equations to the values we know:</em>
<em>Since 3.14 is multiplying B,we can pass it to divide the volume to the left side:</em>
<em>We calculate the operation=</em>
<em>And the answer is 5.2 cm²</em>
<em>Let me know if you have any question :D</em>
Answer:
James is 37, Rob is 44, and Kate is 35
Step-by-step explanation:
Set up an equation where x is James' age:
Rob's age can be represented by x + 7, since he is 7 years older than James
Kate's age can be represented by x - 2, since she is 2 years younger than James
Add these together in the equation and set it equal to 116:
(x + 7) + (x - 2) + (x) = 116
Add like terms and solve for x:
(x + 7) + (x - 2) + (x) = 116
3x + 5 = 116
3x = 111
x = 37
So, James is 37.
Find Rob's age by adding 7 to this:
37 + 7
= 44
Find Kate's age by subtracting 2:
37 - 2
= 35
So, James is 37, Rob is 44, and Kate is 35
The question can be written out like this:
36 = 0.009x
Multiply both sides by 1,000:
9x = 36,000
Divide both sides by 9:
x = 4,000
