selim is ordering concrete spheres to place as barriers in the city park. the spheres cost $2 per square foot, and selim can spe
hoa [83]

The maximum diameter of the spheres he can purchase is  1. 78 ft. Option C

<h3>How to determine the diameter</h3>

The formula for area of a sphere is expressed as;

Area = 4 πr²

If Selim paid $2 per square foot and have a maximum of $20 per square

The area he can purchase is;

= $20/$2

= 10$

Substitute the value into the formula

10 = 4πr²

10 = 4 × 3. 142 ×  r²

10 = 12. 568r²

Make 'r²' the subject

r² = 10/ 12. 568

r² = 0. 79

Find the square root of both sides

r = √0. 79

r = 0. 89

But diameter = 2(radius)

Diameter = 2 × 0. 89 = 1. 78 ft

Thus, the maximum diameter of the spheres he can purchase is  1. 78 ft. Option C

One number is 9 more than another. if the sum of the two numbers is 163​, find the two numbers.
tiny-mole [99]
I think that one number is 77 and the other is 86. 77 + 9 is 86. 86 +77 is 163.

Place values for 249.673
irakobra [83]
Hi! 

This question is worded a little funny, but i think in understand what it's asking. Forgive me if i'm wrong. 

Place values in math are pretty self-explanatory. It's just asking you what place each number is in.

For example:

If you were to write the number 12, the 1 would be in the tens place and the 2 would be in the ones place. 

When speaking about decimals, you pretty much just have to add the letters 'th' to the end of the place value, but instead of decreasing as the numbers grow smaller, you increase and the ones place doesn't exist. 

So in this case:

With 249.637, 2 is in the hundreds place. 4 is in the tens place. 9 is in the ones place. 6 is in the tenths place. 7 is in the hundreths place. 3 is in the thousandths place. 

Hope this helps :)
