Jeffrey is buying mulch for a circular flower garden with a diameter of 12 feet. The layer of mulch needs to be 4 inches thick. What is the volume of mulch needed for the flower garden?
Answers
For anyone doing the USA test prep the correct answer is 37.7 cubic feet!
The volume of mulch needed for the flower garden is approximately 37.68 cubic feet.
Explanation:To find the volume of mulch needed for a circular flower garden, we first need to calculate the volume of the garden. The formula for the volume of a cylinder is V = πr^2h, where r is the radius and h is the height. In this case, the radius is half the diameter, so r = 12/2 = 6 feet. The height is the thickness of the mulch, which is 4 inches or 4/12 = 1/3 feet. Plugging these values into the formula, we get V = π(6)^2(1/3). To simplify further, we can use the approximate value of π as 3.14. Therefore, the volume of mulch needed for the flower garden is approximately 37.68 cubic feet.

If no other money was deposited into or withdrawn from the account, how much was his initial deposit?
PLEASE HELP ME!
Answers
The answer for the first part is 6 years and the answer for the second part is $293.
What is simple interest?It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.
It is given that:
DeShawn deposited $6500 into a bank account that earned 11.5% simple interest each year.
I = Prt
$4485 = 6500(0.115)(t)
t = 6 years
Rich deposited money into a bank account that earned 2.5% simple interest each year.
I = Prt
14.65 = P(0.025)(2)
P = $293
Thus, the answer for the first part is 6 years and the answer for the second part is $293.

How many variable terms are in the expression 3x³y + 5xz − 4y + x − z + 9
Answers
1. 3x^3y
2. 5xz
3. -4y
4. x
5. -z
6. 9
Answer: 6
Step-by-step explanation:
In any algebraic expression a term could be a variable(a,b,c,...), or a constant (numerical value) or a product of variables and a constant.
For example : In expression [tex]5x^2-7xy+4c-4[/tex] , there are 4 terms : [tex]5x^2,\ -7xy,\ 4c\ ,\ -4[/tex]
Let's take one more example : [tex]3y+2x-7xy^2[/tex]
In this expression there are only 3 terms , that are [tex]3y,\ 2x,\ -7xy^2[/tex]
The given expression : [tex]3x^3y + 5xz -4y + x -z + 9[/tex]
There are total 6 variable terms , that are :
[tex]3x^3y ,\ 5xz,\ -4y ,\ x,\ -z ,\ 9[/tex]
Hence, the correct answer is : 6
Randy ' s garden has 3 rows of carrots with 3 plants in each row. Next year, he plans to plant 4 times the number of rows. How many plants will he have next year?
Answers
We first need to multiply the number of rows now with the plants he will plant in each row. 3 x 3 = 9.
Now, we need to do some more multiplication. Since Randy wants to plant 4 times as many rows as this year, we need to multiply the number of rows this year, and the number of rows next year. 4 x 3 = 12.
Now, we can multiply the number of rows with the number of plants. 12 x 3 = 36.
You could have also multiplied the number of rows this year with the number of plants, 3 x 3 = 9. Then, you can multiply that with the number of rows Randy wants to plant next year. 9 x 4 = 36.

if 2.54 centimeters = 1 inch, what would be the length of a ribbon that is 52 centimeters long in inches? ( round to the nearest tenths)
Answers
Well, we know that 2.54 cm = 1 in
We want to find out how many inches are in 52 centimeters. Here's how we start...
We take our known similar information and make that a ratio. We want partial over whole always!
So... 2.54 cm ÷ 52 cm
For the inches... 1 inches ÷ x inches
The reason we use the "x" is because it is a variable (we don't know what that value is yet).
Mentioned before, we know 2.54 cm = 1 in.
So, we can assume the following...
2.54/52 = 1/x
All I did there was state, if 2.54 = 1 then 52 = x.
Now, we can solve for "x" by cross multiplying.
2.54 * x = 52 * 1
2.54 * x = 52
Solve for "x" by dividing
x = 52/2.54
x = 20.47 inches

Juan delivers 174 newspapers every day. Edward delivers 126 more newspapers each day than Juan. Write an expression to show how newspapers Edwards will deliver in 29 days
Answers
300 x 29
Further explanationGiven:
Juan delivers 174 newspapers every day.
Edward delivers 126 more newspapers each day than Juan.
Question:
Write an expression to show how newspapers Edwards will deliver in 29 days.
The Process:
Since Edwards delivers 126 more newspapers every day than Juan, we will count the number of newspapers delivered by Edwards every day.
Edwards: [tex]\boxed{ \ 174 + 126 = 300 \ }[/tex]
Therefore, Edwards delivers 300 newspapers every day.
And now, we will write an expression to show how newspapers Edwards will deliver in 29 days.
We multiply the number of newspapers delivered every day by the number of days requested.
Thus, an expression to show how newspapers Edwards will deliver in 29 days is [tex]\boxed{\boxed{ \ 300 \times 29 \ }}.[/tex]
The summary is as follows:
[tex]\boxed{ \ (174 + 126) \times 29 \ } \rightarrow \boxed{ \ 300 \times 29 \ }[/tex]

How much did Britney earn last week?
Enter your answer in the box.
Answers
Answer:
Britney earn last week $809.25 .
Step-by-step explanation:
As given
itney sells mattresses at a furniture store.
She makes a 9.75% commission on each mattress she sells.
Britney sold four mattresses.
9.75% is written in the decimal form.
[tex]= \frac{9.75}{100}[/tex]
= 0.0975
Now find out the commission of first mattresses.
Mattresses cost = $2400
Commission on first mattresses = 0.0975 × 2400
=$234
Now find out the commission of second mattresses.
Mattresses cost = $3200
Commission on second mattresses = 0.0975 × 3200
=$312
Now find out the commission of third mattresses.
Mattresses cost = $1900
Commission on third mattresses = 0.0975 × 1900
=$185.25
Now find out the commission of fourth mattresses.
Mattresses cost = $800
Commission on fourth mattresses = 0.0975 × 800
=$78
Thus
Total Commission = Commission on first mattresses + Commission on second mattresses + Commission on third mattresses + Commission on fourth mattresses
Put value in the above
Total Commission = $234 +$312 + $185.25 + $78
=$809.25
Therefore the Britney earn last week $809.25 .
