Find the volume of the sphere, round your answer to the nearest tenth
Answer:
904.8 units^3
Step-by-step explanation:
The formula for the area of a circle is [tex]4/3 \pi r^3[/tex]
By the picture we know r = 6
Thus our answer is 4/3 * π * [tex]6^3[/tex]
This is the same as 4/3 * 216 * π = 904.778684234

A company sells cocoa powder in a cylindrical container that is 5 inches long with a circular base of diameter 4 inches. The company is planning to sell a family-size product that will use similar packaging scaled by a factor of 2.
The circumference of the original container is (62.8, 15.7, 12.57, 6.28)
inches. This is (18.84, 9.42, 37.68, 12.57)
inches less than the circumference of the new container.
The circumference of the original container is 12.57 inches.
The cirucmference of the original container is 12.57 inches less than the circumference of the new container.
What is the circumference of the cylinder?The circumference of a cylinder is the distance round the cylinder. It is the perimeter of the cylinder.
The circumference of a cylinder = πD
Where:

6-8x=7x-9x-36 i really need help
Answer:
Simplifying
6 + -8x = 7x + -9x + -36
Reorder the terms:
6 + -8x = -36 + 7x + -9x
Combine like terms: 7x + -9x = -2x
6 + -8x = -36 + -2x
Solving
6 + -8x = -36 + -2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2x' to each side of the equation.
6 + -8x + 2x = -36 + -2x + 2x
Combine like terms: -8x + 2x = -6x
6 + -6x = -36 + -2x + 2x
Combine like terms: -2x + 2x = 0
6 + -6x = -36 + 0
6 + -6x = -36
Add '-6' to each side of the equation.
6 + -6 + -6x = -36 + -6
Combine like terms: 6 + -6 = 0
0 + -6x = -36 + -6
-6x = -36 + -6
Combine like terms: -36 + -6 = -42
-6x = -42
Divide each side by '-6'.
x = 7

How do you find the measure of angle A?
Answer:
m∠A = 18
Step-by-step explanation:
Formula:
the sum of the interior angles of a triangle is 180.
____________________
According to the formula :
[tex]m\angle A\ +\ m\angle B\ +\ m\angle C=180[/tex]
⇔ x - 22 + 3x + 19 + x - 17 = 180
⇔ 5x + (19 - 17 - 22) = 180
⇔ 5x + (2 - 22) = 180
⇔ 5x - 20 = 180
⇔ 5x = 180 + 20
⇔ 5x = 200
[tex]\Leftrightarrow x = \frac{200}{5} \\\Leftrightarrow x = 40[/tex]
Conclusion:
m∠A = x - 22 = 40 - 22 = 18
Can someone please explain 3 and 4 to me? I don’t understand how to solve them
Answer:
see explanation
Step-by-step explanation:
3) line l and m are perpendicular so they intersect at 90 degrees
I labelled the angles that are the same measure.
2x + 23 = 90 subtract 23
2x = 67 divide by 2
x = 23.5 degrees
4) 2m + 66 = 120 subtract 66
2m = 54 divide by 2
m = 27 degrees

of 60° with the ground. Find the distance from the house to the
foot of the ladder.
A 13 feet
)
B 7.5 feet
C 10 feet
D
8.2 feet
Answer:
B
Step-by-step explanation:
assume a right angle between the house and the ground.
then the ladder is the hypotenuse and distance from ladder to house is d
using the cosine ratio in the right triangle and the exact value
cos60° = [tex]\frac{1}{2}[/tex] , then
cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{d}{15}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2x = 15 ( divide both sides by 2 )
x = 7.5
distance from house to foot of ladder is 7.5 feet

Tuesday he used 3/5 as many of 1/8
Answer:
19/40 = 0.475 You can use either the fraction or the decimal
Step-by-step explanation:
3/5 - 1/8 = 3 · 8/5 · 8 - 1 · 5/8 · 5 = 24/40 - 5/40 = 24 - 5/40 = 19/40
Answer:
[tex] \frac{3}{5} - \frac{1}{8} = \frac{19}{40} [/tex]
TOTAL:
=0.475
Step-by-step explanation:
3/5 - 1/8 = 3.8/5.8 - 1.5/8.5 = 24/40
- 5/40 = 24-5/40 - 24-6/40 =19/40
✿For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 8) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 8 = 40. In the following intermediate step, it cannot further simplify the fraction result by canceling.
