Answer:

D. 12.5

Step-by-step explanation:

Volume of a cylinder is V=pi r^2 h

*assuming that they already divided by pi since it isnt in their volume*

We can substitute our values...

5000 = 20^2 h

5000 = 400 h

12.5 = h

Answer:

144/91

Step-by-step explanation:

24/7 ÷ 13/6

Keep the first fraction the same, change the sign, and flip the last fraction to solve

24/7 × 6/13 = 144/91

Answer:

144/91

Step-by-step explanation:

24/7 ÷ 13/6

Keep the first fraction the same, change the '÷' sign to '× ' and reciprocal of the last fraction to solve.  

24/7 × 6/13 = 144/91

Answer:

-3n-4n = 25 + 17

-7n = 42

n= -6

the main thing for here is to combine the like terms and to solve for n which is done by putting all the numbers with variables on one side and the non variables on the other and divide each side by the number that has the variable. Remember that when you bring numbers on the other side, you change its sign, for example if you have 5 on one side and you bring to the other side of the equal sign it becomes -5.

-15 + 15d -7.5d =7.5

15d - 7.5d = 7.5 + 15

7.5d = 22.5

d = 3

for the part where theres 7.5(2d-1)

you multiply each number inside the bracket by 7.5, its called distributivity of multiplication

hope that answers your question

hope you understand what i wrote lol

good luck:)

Answer:

Question 1

Original Equation:

-3n-4n-17=25

Add 17 to both sides (cancels out the -17)

-3n-4n=42

Combine -3n and -4n.

-7n=42

Divide by -7

n = -6

Question 2

Original Equation:

-15+7.5(2d-1)=7.5

Distribute:

-15+15d-7.5=7.5

Add 7.5 to both sides:

-15+15d=15

Add 15 to both sides:

15d=30

Divide by 15:

d = 2

Lesser x = -10

greater x = -2

Step-by-step explanation:

Find the zeroes:-

[tex](x+6)^{2} -16=0[/tex]

[tex](x+6)^{2} =16[/tex]

[tex]\sqrt{(x+6)^{2} }=\sqrt{4^{2} }[/tex]

[tex]x+6=[/tex] ± [tex]4[/tex]

[tex]x+6=4[/tex]

[tex]x=4-6[/tex]

[tex]x=-2[/tex]

or, [tex]x+6=-4[/tex]

[tex]x=-4-6[/tex]

Answer:

X = 10

Step-by-step explanation:

The equation to use would be; 2x + 30 = 5x; because the baker is looking for enough to cover the costs, no more no less.

Then all you have to do is solve for the equation.

2x + 30 = 5x

Subtract 2x from each side

30 = 3x

Divide by 3

10 = x

The baker needs to sell 10 muffins in a day to make enough to cover the revenue.

Blanks in order: Multiplication/multiplying, -7.6-4.4, -12

Step-by-step explanation:

Hi there!

[tex]-7.6-2(2.2)[/tex]

The order of operations: Parentheses, exponents, division/multiplication, addition/subtraction

After exponents is division and multiplication. Because there is no division in the expression, the next step would be multiplying 2 and 2.2:

[tex]= -7.6-4.4[/tex]

Now our final answer after simplifying the above would be:

[tex]= -12[/tex]

Answer:

20

Step-by-step explanation:

First we start off with the Pizza ($13)

Then we add our first 2 toppings to our pizza ($2 + $2 = $4)

And then we add our last 3 toppings to our pizza ($1 + $1 + $1 = $3)

Now we can add all of our costs up to get our answer

$13 + $4 + $3 = 20$

Therefore the cost for this Pizza is $20

Answer:   -12 - 3 = -15

Explanation:

We start at -12 which goes in the first box.

Moving to the left 3 units means we subtract off 3, so that's why 3 goes in the second box.

The arrow is pointing at -15 as the final destination, which goes in the final third box.

Answer:

[tex]\frac{2\sqrt[3]{22} }{7}[/tex]

Step-by-step explanation:

We are asked to find the cube root of [tex]\sqrt[3]{\frac{176}{343} }[/tex]

To solve, let's start with the radical rule of having a fraction within a cuberoot, which is cubing both the numerator and denominator :

[tex]\frac{\sqrt[3]{176} }{\sqrt[3]{343} }[/tex]

Simplify both equations for the answer:

[tex]\sqrt[3]{176} = 2\sqrt[3]{22}[/tex]

[tex]\sqrt[3]{343} = 7[/tex]

[tex]\frac{2\sqrt[3]{22} }{7}[/tex]

Answer:

1. distributive

2. associative

Step-by-step explanation:

In the first one, they are distributing 16 + 23 by the 4.

Therefore it is distributive property as they are splitting and then separately multiplying.

In the second one, the parentheses are shifted. The shifting of parentheses indicates priority, and the associative property says in addition you can choose what you'd like to do first and it won't change the answer.

The equation to find the nth term is:

an = a+(n-1)d

Where a is the first term in the sequence, which is 1 and d is the difference, which in this sequence the next term is found by adding 2 to the previous term, so d = 2 and n is the term you want to find.

The equation is:

an = 1 + (n-1)2

a24 = 1 + (24-1)2 = 1 + 23(2) = 1+46 = 47

Answer:

A, C, D, and F are the rational numbers.

Answer:

a(n)= 120(1/2)^(n-1)

Step-by-step explanation:

60*x=120, x=60/120=1/2 so the sequence goes by a ratio of 1/2

a(n)=b(c)^n-1 and c=1/2. b= a(1)=120 so the formula is a(n)= 120(1/2)^(n-1)

Answer:120(1/2)^(n-1)

Step-by-step explanation:

60*x=120, x=60/120=1/2 so the sequence goes by a ratio of 1/2

a(n)=b(c)^n-1 and c=1/2. b= a(1)=120 so the formula is a(n)= 120(1/2)^(n-1)

Answer:

Science students

When you find the average both plots using median, mean, or interquartile range, you will find that the score for the science students will always be greater than the score of the mathematics students. This is because none of the mathematics students scored higher than the science students, so the mean will always be greater.

MATHEMATICS :

Plot interval = 30 to 50

MEAN :

(34*2) + (40*2) + (32*1) + (33*1) + (35*1) + (37*1) + (39*1) = 324

Sample size, n = (2 + 2 + 1 + 1 + 1 + 1 + 1) = 9

Mean = 324 / 9 = 36

BOTTOM :

SCIENCE :

MEAN : (43*2)+(46*2)+(49*2)+(41*1)+(42*1)+(47*1) =

406

SAMPLE SIZE = (2 + 2 + 2 + 1 +1 +1) = 9

406 / 9 = 45.111

Answer: B (F-D+2=T)

Step-by-step explanation:

We know that daisies has 2 more than the tulips. (D+2 = T)

The answer is B

Flowers - Daises + 2 = T

Since daises has 2 more flowers than tulips, thats why theres a (+2)

Given :-

A square vegetable garden has side lengths of 12 feet.

You plant flowers in the center portion of the garden,a square that has side lengths of 4 feet.

You divide the remaining space into 4 equal sections and plant tomatoes, onions, zucchini, and peppers.

To Find :-

What is the area of the onion section ?

Solution :-

Given that,

→ side of square vegetable garden is = 12 feet .

So ,

→ Area of square vegetable garden = (side)² = (12)² = 144 feet².

Now, given that, inside this area, there is a square of side 4 feet reserved for flowers .

So,

→ The area of the flower section = (side)² = (4)² = 16 feet².

Therefore,

→ The rest of the garden that is intended for vegetables is = The total garden area - The flower section area = 144 - 16 = 128 feet².

Now, this remaining area is to be divided in four equal sections .

So,

→ The area of the onion section = (1/4) of remaining area = (1/4) * 128 = 32 feet². (Ans.)

Hence, The area of the onion section is 32 feet².

Answer:

A) 60 cents

B) 10 pounds of cabbage = 6 $

Step-by-step explanation:

The number of pounds of cabbage = (x)

The price = (y)

(x,y) = (5,3)

That means for 5 pounds of cabbage the price is 3 dollars.

A.

The price for 1 pound of cabbage can be found using this equation
