Answer:
x = 1.23529
Step-by-step explanation:
Step 1: Write equation
3/17 = x/7
Step 2: Solve for <em>x</em>
- Cross multiply: 21 = 17x
- Divide both sides by 17: 21/17 = x
- Rewrite: x = 21/17
- Convert to decimal: x = 1.23529
Answer:
The width is 7 inches, the length is 15 inches
Step-by-step explanation:
If the width is x inches, then the length is 2x+1 inches. Since the perimeter of a rectangle is 2 times the width plus 2 times the length, the perimeter will be 2x+2(2x+1), which simplifies to 6x+2. Since the perimeter is 44 inches, we get the equation 6x+2=44, which makes x=7. So, the width is 7 and the length is 15.
We know that
[the volume of the stack of books]=[area of each book]*[<span>height of the stack]
</span>area of each book=63 in²
height of the stack=15.75 in
<span>so
</span>[the volume of the stack of books]=[63 in²]*[15.75 in]=992.25 in³<span>
the answer is
</span>D) 992.25 in³
.052 = 52/1000 = 26/500 =
13/250
