She needs to buy 6 bags of soil. the correct option is B
Given
Caisha has a circular garden with a radius of 4 ft.
She needs to put a layer of soil on top. e
Each bag of soil covers 9.42 square feet.
What is the radius of a circular garden?The radius of the circular garden is equal to the pie times of the square of the radius.
The radius of the circular garden is;
[tex]\rm Area = \pi r^2\\\\Area = 3.14 \times (4)^2\\\\ Area = 3.14\times 16\\\\Area =50.24[/tex]
Therefore,
The number of bags of soil will she need to buy is;
[tex]\rm = \dfrac{Area }{Soil \ covers}\\\\= \dfrac{50.24}{9.42}\\\\= 5.33\\\\= 6 \ bags \ apporx[/tex]
Hence, she needs to buy 6 bags of soil.

A formula for finding the perimeter of a rectangle is P = 2L + 2W. If you know the perimeter (P) and length (L) of a rectangle, which formula can you use to find the width (W)?
Answer:
p/2 - L = W
Step-by-step explanation:
P = 2L + 2W
Subtract 2L from both sides
P - 2L = 2W
Divide both sides by 2
p/2 - L = W
Answer:
p/2 - L = W

The debt owed is 910$ and the minimum payments is 2.5% or ten dollars whatever is larger. Assume Zach is going to pay only the minimum. If he only pays minimum it would take him 154 months.
Answer:
Monthly rate: 19%/12 ≈ 1.5833%72 months to pay off the loanStep-by-step explanation:
The monthly interest rate is the annual rate (APR) divided by 12.
19%/12 ≈ 1.5833%
The loan will be paid in fewer than 91 months, because Zach will be paying at least $10 per month on his current balance of $910. The attached spreadsheet shows it will take 73 payments to pay off the loan.

A group of 4 friends went to lunch and spent a total of $40, which included the $34 food bill and the tip. They decided to split the bill and tip evenly among themselves. One of the friends used the equation One-fourth (t 34) = StartFraction 40 over 4 EndFraction to represent the situation, where t represents the total amount of the tip. Which describes the amount each friend paid for the food and for the tip? Each friend paid $8. 50 for the food and $1. 50 for the tip. Each friend paid $10. 00 for the food and $6. 00 for the tip. Each friend paid $8. 50 for the food and $6. 00 for the tip. Each friend paid $10. 00 for the food and $1. 50 for the tip.
The amount each friend paid for food is $8. 50 for the food and $1. 50 for the tip.
What is division?The division is one of the most basic mathematical operators. It is used when a number is to be distributed equally in n number of parts.
As it is given that the total of 4 friends went to the lunch, the total amount paid by them is $40, but the food bill was just $34, therefore, the rest of the amount was paid in the tip. If we calculate the tip,
Tip = Total spent - Food bill
Tip = $40 - $34
Tip = $6
Now, as it is that the total amount spend by all on the food is $34, and it is to be divided among the four friends, therefore, the amount paid by each of the friends is,
[tex]\text{Total amount to be paid by each friend}=\dfrac{\text{Total amount spent by all on food}}{\text{Number of friends}}\\\\\text{Total amount to be paid by each friend}=\dfrac{\$34}{4}\\\\\text{Total amount to be paid by each friend}=\$8.5[/tex]
Further, the total amount tip by all is $6, and it is to be divided among the four friends, therefore, the amount paid by each of the friends is,
[tex]\text{Total amount to be paid by each friend}=\dfrac{\text{Total Tip}}{\text{Number of friends}}\\\\\text{Total amount to be paid by each friend}=\dfrac{\$6}{4}\\\\\text{Total amount to be paid by each friend}=\$1.5[/tex]
Hence, the amount each friend paid for food is $8. 50 for the food and $1.50 for the tip.

Those homeworks are so easy lmaøoo
Answer:
To graph the equation of a line written in slope-intercept (y=mx+b) form, start by plotting the y-intercept, which is the b value. The y-intercept is where the line will cross the y-axis, so count up or down on the y-axis the number of units indicated by the b value. From the y-intercept point, use the slope to find a second point. The numerator of the slope tells you how many units to move up or down from the intercept, and the denominator of the slope tells you how many units to move left or right in order to plot the second point. Connect the two points and draw arrows at either end to indicate that the line extends infinitely.
Step-by-step explanation:
Since the equation is in y=mx+B form, M is the value of we can use B as the Y_Intercept and M as the slope.

Answer:
5.2812
Step-by-step explanation:
[tex]10^{x-3.6}-7=41[/tex]
Add 7 to both sides:
[tex]\implies 10^{x-3.6}=48[/tex]
Taking logs of base 10:
[tex]\implies \log_{10}10^{x-3.6}=\log_{10}48[/tex]
Apply log rule [tex]\log a^b=b \log a[/tex]:
[tex]\implies (x-3.6)\log_{10}10=\log_{10}48[/tex]
Apply log rule [tex]\log_aa=1[/tex]:
[tex]\implies (x-3.6)\times 1 =\log_{10}48[/tex]
Simplify and solve:
[tex]\implies x-3.6=\log_{10}48[/tex]
[tex]\implies x=\log_{10}48+3.6[/tex]
[tex]\implies x = 5.281241237...[/tex]
[tex]10^{x-3.6}-7=41[/tex]
Use the rules of exponents and logarithms to solve the equation.
[tex]10^{x-3.6}-7=41[/tex]
Add 7 to both sides of the equation.
[tex]10^{x-3.6}=48[/tex]
Take the logarithm of both sides of the equation.
[tex]log(10^{x-3.6})=log(48)[/tex]
The logarithm of a number raised to a power is the power times the logarithm of the number.
[tex](x-3.6)log(10)=log(48)[/tex]
Add 3.6 to both sides of the equation.
[tex]x=log(48)-(-3.6)[/tex]
Solve by first finding [tex]log(48)[/tex] then subtract [tex](-3.6)[/tex] from the answer:
1. [tex]log(48)=1.6812412373755872181499834821531[/tex]

On Monday, The speed of Tom will be 4 mph.
On Tuesday, The speed of Tom will be 3 mph.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
On Monday Tom takes 15 minutes to walk one mile to school.
On Tuesday he takes 20 minutes to walk the same distance.
Now,
For Monday;
Tom takes 15 minutes to walk one mile to school.
Hence, Distance = 1 mile
Time = 15 minutes = 15/60 hour
Thus, Speed = Distance / Time
= 1 / (15/60)
= 60/15
= 4 mph
For Tuesday;
Tom takes 20 minutes to walk one mile to school.
Hence, Distance = 1 mile
Time = 20 minutes = 20/60 hour
Thus, Speed = Distance / Time
= 1 / (20/60)
= 60/20
= 3 mph
Thus, On Monday, The speed of Tom will be 4 mph.
On Tuesday, The speed of Tom will be 3 mph.

Step-by-step explanation:
A company is using the first two years of its profits to predict what will happen in the future. The profit, p(x), in millions, can be modeled by
the function p(x) =x^2 + 4x + 5, where x, represents the number of years after 2020
- In what year did the company have the largest profit and what was the amount?
Answer:
2022
9 million
Step-by-step explanation:
[tex]p(x) =-x^2 + 4x + 5[/tex]
To find the value of x when the maximum profit occurs, differentiate the function:
[tex]\implies p'(x)=-2x+4[/tex]
set it to zero and solve for x:
[tex]\implies p'(x)=0[/tex]
[tex]\implies -2x+4=0[/tex]
[tex]\implies x=2[/tex]
Therefore, the year in which the company had its largest profit was
2020 + 2 = 2022
Input found value of x into the function:
[tex]p(2) =-(2)^2 + 4(2) + 5=9[/tex]
Therefore, the amount was 9 million
