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.
Answer:
no, he used radius instead of diameter

I am thinking of a number.
My number is a multiple of 8
What three other numbers must my number be a multiple of?
Answer:
2, 4, and 1
Step-by-step explanation:
The required numbers are 1, 2, and 4 which are a multiple of eight.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.
Let's assume the number would be x
if it is a multiple of 8 then it can write as this :
x = 8k
8 = 2 × 4k
x = 2 × 4k
If the number is a multiple of eight then it is a regular number.
Every regular number is a multiple of one.
So, x = 1 × 2 × 4k
Therefore, the required numbers are 1, 2, and 4 which are a multiple of eight.

Justin is 2years older than one third Marcellas age. Aimee is four years younger than 2 times Justin's age. Define a variable and write an expression to represent Justina age. Than find Justina age and aimees age if Marcella is 63 years old
Answer:
Justin is 23 years old, and Aimee is 42 years old.
Step-by-step explanation:
Let Marcella's age be represented by x, and Justin's age by t.
Given that Justin is 2 years older than one third Marcella's age.
t = [tex]\frac{1}{3}[/tex] x + 2
t = [tex]\frac{x}{3}[/tex] + 2 ........... 1
Also, Aimee is four years younger than 2 times Justin's age.
Aimee = 2 x t - 4
Aimee = 2t - 4 .......... 2
But, Marcella's age is 63 years, so that from equation 1;
Justin's age = [tex]\frac{x}{3}[/tex] + 2
= [tex]\frac{63}{3}[/tex] + 2
= 21 + 2
= 23
Justin is 23 years.
From equation 2,
Aimee = 2 x 23 - 4
= 46 - 4
= 42
Aimee is 42 years.
Therefore,
Marcella is 63 years old, Justin is 23 years old, and Aimee is 42 years old.
1. Pencils come in packages of 10. Erasers come in packages of 12. Phillip wants to purchase the smallest number of pencils and erasers so that he will have exactly 1 eraser per pencil. How many packages of pencils and erasers should Phillip buy?
A. 4 packages of pencils and 3 packages of erasers B. 5 packages of pencils and 4 packages of erasers C. 6 packages of pencils and 5 packages of erasers D. 12 packages of pencils and 10 packages of erasers
Answer:
C. 6 packages of pencils and 5 packages of erasers
Step-by-step explanation:
Pencil = packages of 10
Erasers = packages of 12
Find the lowest common multiple of 10 and 12
10 = 20, 30, 40, 50, 60, 70, 80
12 = 24, 36, 48, 60, 72, 84, 96
The lowest common multiple of package of pencil and eraser is 60
Packages of pencil = 60 / 10
= 6 packages
Packages of eraser = 60 / 12
= 5 packages
C. 6 packages of pencils and 5 packages of erasers

Answer:
(-3,0)
Step-by-step explanation:
So first we wanna find how for the x value is on point a to point b and how far the y value is from point a to point b. the x on point a is 9 units away from point b and y is 18 units away. Then we find out what 2/3s of 9 and 18 is which would be 6 and 12. So then we take the A coordinates (9,-6) and subtract 12 from the x value and 6 from the y value to get the new coordinates of (-3,0)

Find the sides marked with letters:
m = ? z = ?
Answer:
z = 4.8
m = 5 1/3
Step-by-step explanation:
Here, we want to get and z
We use the principle of similar triangles
5/3 = 8/z
5z = 24
z = 24/5
z = 4.8
To get m;
3/m-2 = 4.8/m
3m = 4.8(m-2)
3m = 4.8m - 9.6
4.8m - 3m = 9.6
1.8m = 9.6
m = 9.6/1.8
m = 5 1/3

Answer: $6,120
Step-by-step explanation:
There are 15 fruits in each basket.
The store shipped 3,825 fruits, to find the number of baskets of fruits shipped you have to divide 3,825 by 15.
3,825 ÷ 15 = 255
Each basket costs $24 so to find the cost of 255 baskets, you multiply 255 by 24.
$24 × 255 = $6,120
Leona earned $6,120 from the gift baskets sold.

Answer:
1) B=-12
2) 189.69
Step-by-step explanation:
Explanation 1: To find B, we have to replace the given points in the equation, that is , x=2 and y=1
[tex]3x+By+6=0\\3.2+B.1+6=0[/tex]
Then we solve for B.
[tex]6+B+6=0\\B+12=0\\B=-12\\[/tex]
Hence , B=-12
explanation 2: you have the following equation for the number of liters 3% milk:
[tex]0.03+0.1(200)-x=0.05(200)[/tex]
Solve the previous equation for x:
[tex]0.03x+20-x=10[/tex]
[tex]0.03-x=10-20\\-0.97x=-10\\x=10.31[/tex]
Hence , there are 10.31 liters of 3% milk
Add the numbers of liters 10% butterfat is :
[tex]200-10.31=189.69 liters[/tex]
