Is Noah's work correct? Explain. Yes, Noah's calculations are correct. No, Noah did not simplify correctly. No, Noah used the di
ivolga24 [154]

Answer:

No, Noah used the diameter instead of the radius in the calculations.

V = 91.13π

Step-by-step explanation:

Noah is working on a geometry problem that involves finding the volume of a sphere with a diameter of 9 units. His work is shown below.

V = πr3

V = π(9)3

V = π(729)

V = 972π cubic units

Is Noah’s work correct

Volume of a sphere, V = πr³

radius, r = diameter / 2

Diameter = 9 units

r = 9 / 2

= 4.5 units

Volume of a sphere, V = πr³

= π × 4.5³

= π × 91.125

= 91.125π

Approximately 91.13π

V = 91.13π

No, Noah used the diameter instead of the radius in the calculations.

The formula for finding Combination is given as;

Combination = n!/ r!(n -r)!

n = 135

r = 2

Combination = 135!/ 2!(135 - 2)!

Thus, the method to use is Combination

Find the GCF between 24 and 36 by prime factorization:24 = 2 * 2 * 2 * 336 = 2 * 2 * 3 * 3Now, notice that the common between the prime factorization of both numbers are 2*2*3 which is what we call Greatest Common Factor and over here equal to 12.Take 12 as a common factor in the above addition:24 + 36 = 12 ( 2 + 3 )

The table below shows the prices for shoe rental, games, and snacks at a bowling alley.
Natalka [10]

Answer:

Step-by-step explanation:

Hello!

Alright, first, we will need to find the total of these items.

Shoe Rentals= $2.75

One Game of Bowling= $2.50

Large Soda: $1.50

The problem says he paid for three shoe rentals, three games of bowling, and two large sodas.

$2.75(3) + $2.50(3)+$1.50(2)=?

$8.25     + $7.50    + $3.00= $18.75

But it says which represents the change in his bank account after his purchase.

I believe your best answer here would be $-18.75

I hope this helps!
