Answer:
2814.87
Step-by-step explanation:
Answer:
2,813.44 cubic feet
Step-by-step explanation:
Given,
Height of a cylinder = 14 feet
Radius of a cylinder = 8 feet
Hence, volume of the cylinder
\( = \pi {r}^{2} h\)
\( = 3.14 \times 8feet \times 8feet \times 14feet\)
= 2,813.44 cubic feet (Ans)

What is an equation in the form y=kx that relates the sale price to the retail price x?
Answers
An equation that can be used to find the markup on the cost x of a phone is y = 2.50x, where y represents the markup amount.
Using the equation, the markup amount can be calculated as y = 2.50($12) = $30.
The retail price of a phone is the cost price plus the markup amount, which is $12 + $30 = $42.
The percent the sale price of $31.50 is of the retail price $42 can be calculated as (31.50/42) x 100% = 75%.
The sale price is 25% less than the retail price. Therefore, the markdown rate is 25%.
An equation in the form y=kx that relates the sale price to the retail price x is y = 0.75x, where y represents the sale price.

Courtney has $21.50 to buy a gift for her brother. She found a stuffed animal that costs $19.65. With 10.1% sales tax added on, what is the sales tax? What is the total cost of the stuffed animal with tax included? Will Courtney have enough money to buy the gift?
The sales tax is: $_________
The total cost is: $_________
Is it enough money?
Answers
Answer:
Sales tax: 1.98465 which in this case is $1.98 (take note that you can round and it would be $2)
The total cost: $21.63 so no, Courtney cant buy the stuffed animal :(
Step-by-step explanation:
You can find the sales tax by dividing 10.1 by 100 to get 1.984...then rounding that number to get $1.98 since we are working with money in this problem then we have to find the total cost by adding our sales tax ($1.98) to our original cost ($19.65) to get our FINAL answer of $21.63

I need help arranging cards in a 4 x 4 grid with numbers 1-9 so that the sum of each row and each column is 20. This what the grid looks like:
Answers
Answer:
8, 2, 8, 2
7, 3, 7, 3
6, 4 6, 4
9, 1, 9, 1
Step-by-step explanation:
In the picture, it shows two of each number so I'm gonna base it off the picture but let me know if I should base it off the wording.
So we know that half of 20 is 10. This will be valuable information. So we need the sum of two numbers to equal 10. So for the rows we can just do 8+2+8+2, 7+3+7+3, 6+4+6+4, 9+1+9+1.
Since there are 18 numbers, I'm assuming we don't have to use all of them.

91ft^2
Step-by-step explanation:
A = w*l
first, solve for the bottom rectangle
w = 7ft
l = 8ft
7ft * 8ft = 56ft^2
then for the second rectangle
l = 5ft
w = 7ft
5ft*7ft = 35ft^2
total area = rectangle 1+2
so 35ft^2+56ft^2=91ft^2
Answer:
The answer for the Area of the shape is 91ft²
Step-by-step explanation:
Area of the shape =Area of Bigger rectangle+ Area of small rectangle
A=L×B+l×b
A=7×8+5×7
A=56+35
A=91ft²

Complete the following statement: The equation is (false, true) when x = 4, so 4 (is, is not) a solution.
Answers
Answer:
False, is not
Step-by-step explanation:
If we plug in 4 for x in the equation, we get that 5 * 4 + 3 = 12, and we can calculate that 20 + 3 = 12, which is not true. 4 is a false solution for that equation so it is not a solution (We can use this info to say that the answer is false, is not).

the measure of angle ABD is 134 degrees. what is the measure of x? What angle relationship is needed to be solved?
Answers
Explanation
The angles ABD and DBC are supplementary since they form a straight line. That means they add to 180 degrees.
(angle ABD) + (angle DBC) = 180
(134) + (2x) = 180
2x = 180-134
2x = 46
x = 46/2
x = 23
Answer: x=23 and the angle relation used was supplementary angles
Step-by-step explanation:
first, you know that angle abd is 134 so you subtract that from 180 and divide it by 2 because angle cbd is 2x and you know they equal 180 because they make a straight line.
Find the volume of a regular cube if the length of a side is 10 cm. (Hint: V = I³.)
Answers
Answer:
1000 cm
Step-by-step explanation: I can't explain it sorry.
Answer:
1000cm
Step-by-step explanation: The reason why the answer is 1000cm is because a cube has all equal sides. So if one side is equal to 10, then that means all the other sides are also equal to 10. The formula to find the Volume of a cube is finding the measurment of one side and multiplying it by itself 3 times. Or you can use the formula they have given you V=I^3
In this case V means volume and I means the length of one side.
So we would substitute the formula to V = 10^3
10*10*10= 1000
Several students measured a 25-mm-long nail and wrote the measurements shown in the table below. Whose measurement had the greatest percent error? Round to the nearest percent.
Please answer the question completely and correctly so I can give you a 5-star rating and thanks.
Answers
Answer:
The student whose measurement had the greatest percent error was student 5. Their measurement was 27 mm, and the actual length of the nail was 25 mm. To find the percent error, we use the formula:
percent error = |(measured value - actual value) / actual value| x 100%
Plugging in the values we get:
percent error = |(27 - 25) / 25| x 100% = 8%.
So student 5's measurement had a percent error of 8%.

How do you knowv what method (Ss SAS ASA AAS) TO Use when proving triangle congruence?
Provide the definitions of these congruengy methods.

Answers
Answer:
You know what method to use by looking at the markings on the triangle, shape.
Step-by-step explanation:
SSS means that the three sides of the triangle are congruent to the sides of the other triangle
SAS means that two sides and one angle of a triangle are congruent to the two sides and one angle of another triangle. Note: The angle should be in between the two sides
ASA means that two angles and one side of a triangle are congruent to the two angles and one side of another triangle. Note: The side should be in between the two angles
AAS means that two angles and one side of a triangle are congruent to the two angles and one side of another triangle. Note: this is not like ASA while ASA means that the side is in between the two sides, AAS means that the side is not in between the two angles and instead next to it.
Hope this helps
The different triangle congruency postulates are; SSS, SAS, AAS, ASA.
What are the Triangle Congruency theorems?
1) SSS is an acronym for Side - Side -Side Congruency theorem and it tells us that the three corresponding sides of two triangles are congruent to each other.
2) SAS is an acronym for Side - Angle -Side congruency postulate and it tells us that two corresponding sides and one corresponding included angle of two triangles are congruent to each other.
3) ASA is an acronym for Angle - Side - Angle Congruency Postulate and it tells us that two corresponding angles and one corresponding included side of two triangles are congruent to each other.
4) AAS is an acronym for Angle - Angle - Side Congruency postulate and it tells us that means that two corresponding angles and one corresponding non-included side of two triangles are congruent to each other.
