The volume of a right cylindrical water tank is 5000 cubic meters. The radius of the base of the tank is 20 meters. Find the length in meters, of h, the hight of the tank.
A. 15 m B. 10 m C. 10.5 m D. 12.5 m

Answers

Answer 1

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

A) 4m + 3

B) 3m + 4

C) 3m – 4

if Natalie has 4 more ( adding 4 more marbles) marbles that are already 3 times Juan has ( multiplying by 3) then the answers for A and C don't make since the amount of marbles is multiplied by 3 and adds 4. Bis the correct option.

Hannah baked twice the number of cookies Sam baked. Sam baked 36 cookies. Let c represent the number of cookies Hannah baked.

Which equation shows an equality between two different ways of expressing how many cookies Sam baked?

A) 36 = c – 2

B) 36 = c + 2

C) 36 = c ÷ 2

if Hannah made twice as many cookie as Sam that means the amount of cookies Hannah made are equivalent to 36 x 2= c. if we were to multiply 36 x2 we'd get how many cookies Hannah made and if we needed to find out how many Sam made we'd have to divide  Hannah's cookies by two. giving us 36 = c ÷ 2. making C the correct option.

Question,

Three pumpkins are catapulted at a contest. How much farther does Pumpkin C travel than Pumpkin A?

• Pumpkin A travels 0.61 mile.

• Pumpkin B travels 0.28 mile farther than Pumpkin A.

• Pumpkin B travels 0.06 mile farther than Pumpkin C.

How many Mile ____

Answers

Answer:  0.34

============================================================

Explanation:

A = 0.61 is given to us

Pumpkin B travels 0.28 of a mile further than A does, so,

B = A+0.28 = 0.61+0.28 = 0.89

Pumpkin B travels 0.89 of a mile.

---------------------

Pumpkin C travels 0.06 of a mile more than B does, which means,

C = B + 0.06

C = 0.89 + 0.06

C = 0.95

Pumpkin C travels 0.95 of a mile.

---------------------

The last thing to do is to subtract the values of C and A

C - A = 0.95 - 0.61 = 0.34

Pumpkin C travels 0.34 of a mile further compared to pumpkin A.

---------------------

Side note: if you want to convert from miles to feet, then multiply by 5280.

For instance, 0.61 miles = 0.61*5280 = 3,220.8 feet.


If Pumpkin B travels 0.28 farther than A and 0.06 farther than be 0.28-0.06= 0.22 miles so the answer is 0.22 for pumpkin C

What is the solution to the following system of equations: 2x + 3y = 5 AND 5x = 5y -25

Answers

Answer:

point form (-2,3)

Equation form

x=-2, y=3

Step-by-step explanation:

solve for the first variable in one of the equation, then substitute the result into the other equation.

Answer:

(-2,3)

Step-by-step explanation:

5x=5y-25

x=y-5    divide both sides by 5

use substitution.

2(y-5)+3y=5

2y-10+3y=5    distribute the parenthesis

5y-10=5    combine like terms

5y=15    add 10 to both sides

y=3    divide both sides by 5 to get y alone

5x=5(3)-25    replace y with 3, the value we found above

5x=15-25    multiply 5 and 3

5x=-10    subtract 25 from 15

x=-2    divide both sides by 5 to get x alone

NEED HELP ASAP NO FALSE ANSWERES. Part B: Scarlett made a profit of $250.00 with her mobile car wash company. She charged $75.00 per car wash and received $35.00 in tips, but also had to pay $5.00 in
cleaning supplies per car wash. Write an equation to represent this situation

Answers

Answer:

y = 70x + 35

Step-by-step explanation:

$75 - $5 = $70 (this is the amount charged minus the amount needed to get the job done per car wash)

the +35 is the tips extra/ constant that will be added after the jobs are done.

x is the amount of car washes done

y would be the profit received.

thus y = 70x + 35 (profit = value of car wash * number of cars washed + tips)

Answer:

Step-by-step explanation:

Profit = Income less outgo

         = (car wash income + tips) - (supplies)

$250 = ($75n + $35) - ($5n), or

$215  = $70n     (where n represents the number of cars washed)

This comes out to n = $215/$70, or approximately 3 car washes.

How many three digit numbers have digits whose sum is greater than 2?

Answers

Answer:

896

Step-by-step explanation:

Let's talk first about how many 3 digit numbers there are. The first 3 digit number is 100 and the last is 999. So there are 999-100+1 numbers that are 3 digits long. That simplifies to 900.

Now let's find how many of those have a sum for the digits being 1, then 2 ? Then take that sum away from the 900 to see how many 3 digit numbers have the sum of their digits being more than 2.

3 digit numbers with sum of 1:

The first and only number is 100 since 1+0+0=1.

We can't include 010 or 001 because these aren't really three digits long.

3 digit numbers with sum of 2:

The first number is 101 since 1+0+1=2.

The second number is 110 since 1+1+0=2.

The third number is 200 since 2+0+0=2.

That's the last of those. We could only use 0,1, and 2 here.... Anything with a 3 in it would give us something larger than or equal to 3.

So there are 900-1-3 numbers who are 3 digits long and whose sum of digits is greater than 2.

This answer simplifies to 896.

there are 896 three digit numbers whos sum is greater than 2 i think

Answers

Answer:

1. 28

2. -65

Step-by-step explanation:

The rule I learned, was that if there is an even number of negative signs, the outcome is positive. If there is an odd number of negative signs, the outcome is negative.

In the first question, we have 2 negative signs. So the outcome is positive. 28 is positive.

In the second, we have 3 negative signs, so the outcome is negative. -65 is negative.

Step-by-step explanation:

By using cross multiplication we can figure out how many grams of Toasty Oats is needed for 9 grams of protein:

[tex]\frac{12}{100}* \frac{9}{x}[/tex] (x) being the grams of toasty oats.

Cross multiply: 12x = 900

solve for x: 900/12 = x

x = 75 grams of toasty oats needed for 9 grams of protein

To find which one has the better ratio of proteins to grams of cereal,

we can multiply the amount of cereal together to get the same denominator

12/100 and 5/45

12/100 * 9

5/45 * 20

to get the same denominator

108/900 and 100/900

we can see the (12/100)*9 has more protein to grams of cereal ratio than (5/45)*20.

Step-by-step explanation:

We can find an equivalent expression by using distributive property

Distributive property: whenever there is a number outside of the parenthesis you multiply that number by whatever is in the parenthesis

So for -6(-7+2z) we would multiply the number outside of the parenthesis (-6) by what's inside of the parenthesis ( -7 and 2z )

-6 * -7 = 42

-6 * 2z = -12z

An equivalent expression would be 42 - 12z
