Apex Learning Study 4.2.1 What units do you use to report the area of a circle with a radius of 50 feet?
Answer:
in square feetStep-by-step explanation:
Area of anything is allways reported in square units. Usually that is square of given unit because it's the simplest way:
R = 50 ft
A = πR² = π•(50 ft)² = π • 50 ft • 50 ft = 2500π ft² ≈ 7854 ft²
{Of course you can re-calculate the units, ex.:
3 feet = 1 yard so 50 ft = 50/3 yd then
A = πR² = π•(50/3 yd)² = π • 50/3 yd • 50/3 yd = 2500/9 π yd² ≈ 872.7 yd² }

\(\frac{5}{12}\) cups of dog food is recommended for a 25-pound adult dog.
Step-by-step explanation:
Unitary method: diving the number that you want to find out over the already known number. (just try to understand this lol) :)
10 lb = ⅙ Or 0.1666666 cups
1 lb = ? cups
\(\frac{0.16}{10}\) = 0.01666666
1 lb = 0.01666666 cups
25 lb = 0.01666666 × 25 cups
25 lb = 0.416666667 Or \(\frac{5}{12}\) cups
(Or: 10lb= ⅙ 20lb= ⅙+⅙ = \(\frac{2}{6}\) 5lb= ⅙ ÷ 2= \(\frac{1}{12}\) (10lb÷2) 25lb = \(\frac{1}{12}+\frac{2}{6}\) = \(\frac{5}{12}\) ≈ 0.416666667 (25=20+5)
How many pictures can you save at one time to the photo stream on your cell phone? Solve the equation you wrote in part a to find the unknown variable.
Answer:
Answer: 4(p - 7) = 44
First distribute the 4 over the parentheses
4p - 28 = 44
Add 28 to both sides:-
4p = 44 + 28
4p = 72
Divide both sides by 4:-
p = 72/4
p = 18

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500

Answer:20.7 units²
Step-by-step explanation: volume of a rectangular prism is L×W×H
therefore 82.8=L×W×the height which is 4 units so if u do 4×L×W you get 4LW which is the volume
(4LW=82.8) now divide 82.8 by 4LW to get the value of LW. The value of LW is an area of one of the bases because area is L×W which is basically LW

Answer:
4 inches wide
Step-by-step explanation:
We see that 984 ÷ 328 = 3, so the real Eiffel Tower is 3 times as tall as it is wide. So the scale model must also be 3 times as tall as it is wide. If the scale model is 12 inches tall, then it is 12 ÷ 3 = 4 inches wide.

the volume of the right circular cylinder in 144π cubic yards. if h, the height of the cylinder is 4 yards, what is r, the radius of the base?
Answer:
r = 6
Step-by-step explanation:
The formula for the volume of a cylinder is V = πr^2h,
If the volume of the cylinder is 144π cubic yards and the height of the cylinder is 4 yards it can be written as 144π = πr^2 * 4
You can then solve for r by dividing both sides of the equation by 4π:
r^2 = 36
r = 6

Answer:
1)13/3
2)-1/2
3)5/6
Step-by-step explanation:
1) the negatives cancel
2)(3/4)/(9/16) --> (3/4)*(16/9) --> 4/3
3) (4/3) + (9/3) = 13/3
1)-6+4 = -2
2)-1+5 = 4
3)-2/4 --> -1/2
1)8-(5+(3(-4))) = 15
2)4^2 +2 = 18
3)15/18 --> 5/6
The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

Answer:
1) x = -11
2) x= -9
3) x = -1
4) x = 32
5) x = 11
Step-by-step explanation:
Answer:
Step-by-step explanation:
11. -1= (5+x)/6 : to get rid of the 6 on the bottom multiply to both sides.
-6=5+x : subtract 5 to both sides
-11 = x
12. 2/3x + 2 = -4 : subtract the 2 to both sides
2/3x = -6 : divide 2/3 to both sides
x= -6/(2/3)
x=-9
13. 7x+2.5=-4.5 : subtract 2.5 to both sides
7x= -7 : divide by 7 to both sides
x= -1
14. 8-3/8x= -4 : subtract 8 to both sides
-3/8x = -12 : divide both sides by -3/8
x=32 : two negatives make a positive
15. -3x - 5 = -38 : add 5 to both sides
-3x=-33 : divide both sides by -3
x= 11 : two negatives make a positive

(−3x^2+5x-2)-2(x^2 — 2x − 1) In the expression above is rewritten in form ax^2+ bx +c, where a, b, and c are constants, what is the value of b?
Answer:
value of (b) will be: 9
Step-by-step explanation:
Answer:
b = 9
Step-by-step explanation:
(-3x² + 5x - 2) - 2(x² - 2x - 1) =
= -3x² + 5x - 2 - 2x² + 4x + 2
= -5x² + 9x
= ax² + bx + c
a = -5; b = 9; c = 0
