Brainliest:Cube A has a side length of 4 cm. Cube B has sides that are twice as long as Cube A. Find the volumes of Cube A and Cube B.
Answer:
Step-by-step explanation:
96 sq. cm. for cube a and cube b is 192sq cm
Answer:
Cube A: 64³ cm
Cube B: 512³ cm
Step-by-step explanation:
Since we know these figures are cubes, we only need to know the length of one side, 4. To find Cube A’s volume, we multiply 4 times 4 times 4 to get 64. Cube A has a volume of 64³ cm.
We know Cube B’s sides are twice as long as Cube A, so they have to be 8 cm. 8 times 8 times 8 is 512. Cube B has a volume of 512³ cm.

Apollo traveled 54 leagues in 3 days. Then he tripled his rate. How long would it take him to travel 594 leagues at this new speed?
Answer:
11 days
Step-by-step explanation:
First, you have to find the original rate. Then, multiply that by three. Lastly, take 594 and divide by the tripled number.
54 ÷ 3 = 18
18 x 3 = 54
594 ÷ 54 = 11

HELP PLEASE Three cylinders have a height of 8 cm.... Find the volume of each cylinder. Round all answers to the nearest hundredth. Use 3.14 for pi.
Step-by-step explanation:
Just use the equation for volume of a cylinder
For cylinder 1
V=(3.14)r^2h
V=(3.14)1^2(8)
V=(3.14)(1)(8)
V=25.12 cm
For cylinder 2
V=(3.14)r^2(h)
V=(3.14)(2^2)(8)
V=(3.14)(4)(8)
V=100.48 cm
For cylinder 3
V=(3.14)r^2(h)
V=(3.14)(3^2)(8)
V=(3.14)(9)(8)
V=226.08cm
If your confused or have a question just ask
Hope this helped :)
Answer:
Step-by-step explanation:
The volume of the cylinder is calculated by multiplying the area of its base by its height. The height of the cylinder is 8 inches (the height of the cube through which it is being drilled). Therefore, its volume is πr2h = π * 3.752 * 12 = 168.75π in3.
Emily noticed that on halloween, her child got three basic types of candy: chocolate, gummy, and hard candy. She has 15 more hard candies that chocolate, and 5 less than twice the amount for gummy candy than chocolate. if she had a total of 178 pieces of candy, how many of each type did she get?
Answer: gotta scroll down sry
Step-by-step explanation:
First set up equations with variables that show the information you have:
c = chocolate // g = gummy // h = hard candy
178 = c + g + h
h = c + 15
g = 2c - 5
Then, solve all the equations for a number:
178 = c + g + h (leave as is)
15 = -c + h (subtract 'c' from the original equation's right side and switch the sides of the equation)
-5 = -2c + g (subtract '2c' from the original equation's right side and switch the side of the equation)
Then, line up all the variables and subtract the top equation by the lower two:
178 = c + g + h
15 = -c + 0g + h
-5 = -2c + g + 0h
---------------------------
168 = 4c + 0g + 0h >>>> 168 = 4c
Solve for 'c' and plug it into the other equations to find 'h' and 'g':
168/4 = 4c/4
42 = c
15 = -(42) + h -5 = -2(42) +g
57 = h 79 = g
Add all the numbers together to double-check:
42 + 57 + 79 = 178
chocolates = 42
gummies = 79
hard candies = 57

Answer: The answer the second option
Step-by-step explanation:Because since 270 degrees counterclockwise is equal to 90 clockwise you would use the 90 formula and swap the x and y and add a negative to the x and if you do that with each on the second d option should match you answer exactly.

You have 2 different savings accounts. For Account A, the simple interest earned after 9 months is $6.75. For Account B, the simple interest earned after 21 months is $19.25. If the interest rate is 3.6% for Account A and 2.2% for Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain your answer.
Answer:
Account A Principal: $250
Account B Principal : $500
Account B earned $0.17 more interest in the first month
Step-by-step explanation:
Let the principal in account A be PA and the principal in account B be PB
Simple interest I = Prt where P is principal, r is interest rate (in decimal) and t - time in years
Therefore, given interest I
P = I/rt
We will assume both interest rates are annual interest rates
For account A, interest = 3.6% per year
This works out to 0.036 per year
For account B, interest = 2.2% which works out to 2.2/100 per year = 0.022 per year
Account A
I = 6.75, r = 0.036 t = 9 months = 9/12 year = 3/4 year = 0.75 year
PA = 6.75/(0.036 x 0.75) = $ 250.00
Account B
I = 19,25, r = 0.022, t = 21/12 = 1.75 years
PB = 19.25/(0.022 x 1.75) = P = $ 500.00
Account A interest earned per month = 6.75/9 = $0.75
Account B interest earned per month = 19.25/21 = $0.92
Hence account B earned more interest in the first month
The amount of interest earned by account B over account A
= 0.92 = 0.75 = $0.17

Reflect the point (-3,-8) across the y-axis
Reflect the point (-3,-8) across the x-axis
Step-by-step explanation:
When reflecting a point across an axis, that means the opposite coordinate will switch signs.
Reflecting a point across the YAXIS means that the X coordinate will switch signs
Reflecting a point across the XAXIS means that the Y coordinate will switch signs
Taking (-3, -8)....
Reflecting it across the y-axis, we will flip the sign of the X coordinate. It's -3, so we make that +3, giving us
(3, -8)
Reflecting across the x-axis, we will flip the sign of the Y coordinate. it's -8, so we make that +8, giving us
(-3, 8)

The radius of the base of the cone is √189 ft.
What is the Pythagorean theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. The theorem can be used to determine how steep mountains or slopes are. To calculate the distance between an observer and a location on the ground when the observer is looking down from a tower or structure. It is mostly utilized in the construction industry.
For question 5 :
Given a right-angle triangle that has a hypotenuse of 14 and a base is 9 cm.
From the Pythagorean theorem:
Hypotaneuse² = base² + height²
14² = 9² + height²
height² = 196 - 81
height² = 115
height = √115
For question 4:
The distance from the top of the cone to the edge is 15 feet. The height of the cone is 6 feet.
The radius of the cone = base pf right angle triangle
From the Pythagorean theorem:
Hypotaneuse² = base² + height²
15² = base² + 6²
225 - 36 = base²
base = √189

The distance from the plane to the airport is = 3.35 * 10,000ft

Step-by-step explanation:
To find out the number you can divided 102 by 1.2 and you get 85 meaning 85 is the answer.
Answer:
A;
Step-by-step explanation:
120% = 1.2 (decimal form)
Therefore: 1.2 x w = 102 or 102 = 1.2 x w
102 = 1.2 x w
Divide both sides by 1.2 to get:

the value of the x and y for the given system of equations are 6, and -2 respectively.
What are Systems of equations?Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
Given, a system of equations
2x + 5y = 2
2x - 5y = 22
Adding both equations:
4x = 24
x = 6
From equation 1
2 * 6 + 5y = 2
5y = -10
y = -2
Therefore, the value of the x and y for the given system of equations are 6, and -2 respectively.
