Answer:
Step-by-step explanation:
Let the base is x, then the legs are 2x each.
<u>The perimeter is:</u>
- x + 2x*2 = 50
- 5x = 50
- x = 10
The base is 10 cm and legs are 20 cm each.
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 method to use is Combination
<h3>What is combination?</h3>
Combination is a way or method of selecting items from a collection without a defined order or manner.
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 )
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!
