Answer:
Area = 1808.64 cm
Step-by-step explanation:
Circumference of a circle = 2πr
Circumference = 150.72
π = 3.14
r = radius
150.72 = 2 x 3.14 x r
150.72 = 6.28 r
r = 150.72/6.28
r = 24cm
Radius = 24
Area of a circle = πr²
Area = 3.14 x 24²
Area = 3.14 x 576
Area =1808.64 cm
Answer:
1808.64 cm

General Formulas and Concepts:
Algebra I
Reading a Cartesian planeCoordinates (x, y)Function NotationStep-by-step explanation:
What g(-4) is saying is what the output of the function g(x) when x= -4. According to the graph, when x = -4, y = 1.
∴ g(-4) = 1
if tantheta -cottheta =a and costheta +sintheta =b then 4b^2(2-b^2)
Answer:
= 4(1+sin2theta)²
Step-by-step explanation:
Given the equations
tantheta -cottheta =a... 1
costheta +sintheta =b .... 2
We are to find 4b^2(2-b^2)
Squaring both sides of equation 2
(costheta +sintheta)^2 = b^2
cos^2theta + 2costheta sintheta + sin^2 theta = b^2
(cos^2theta+ sin^2 theta) + 2costheta sintheta = b^2
1 + 2costheta sintheta = b^2
1 + sin2theta = b^2
substitute
4b^2(2-b^2)
= 4(1+sin2theta)(2-1+sin2theta)
4(1+sin2theta)(1+sin2theta)
= 4(1+sin2theta)²
There are red and green apples in a crate.
There are 60 green apples in the crate.
The ratio of the number of red apples to green apples is 1:5
Georgia puts in some more red apples into the crate.
The ratio of the number of red apples to green apples is now 2:3
How many red apples does Georgia put into the crate?
Answer:
28
Step-by-step explanation:
60 apples by 5 is 12. When Georgia put some more apples in we now have to divide 60 by 3 which is 20 and then multiply that by 2 which is 40. So, if the ratio was 1:3 it would be 20:60 but it is 2:3 so the answer is 40:60. Do 40 minus 12 to find how much Georgia added. 40 minus 12 is 28.

Step-by-step explanation:
Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.
y=57(0.4)^x
Answer:
Decay, 60%
Step-by-step explanation:
Remember that the exponential function is written in the form [tex]y=ab^x[/tex]. In this problem, a=57 and b=0.4. A function is considered a growth function when [tex]b>1[/tex]. Since 0.4 not greater than 1, this is an exponential decay function.
Now, to find the rate of decrease we can use part of the form [tex]y=a(1-r)^x[/tex].
[tex]1-r[/tex] represents the percentage decrease, in this case, 0.4. If that entire term is 0.4, we need to solve for [tex]r[/tex].
[tex]1-r=0.4\\r=0.6[/tex]
So, the rate of percentage decrease is 60%.
I hope this helps!
Use the Pythagorean Theorem to find the length of the leg in the triangle shown below. 5, 13
Answer:
Leg= Leg- hypotenuse
Step-by-step explanation:
5 suquared= 25
13 squared= 169
25+169 =194
194 square root is 13.9
How to determine each side of a right triangle
if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)
if leg b is unknown, then. b = √(c² - a²)
for hypotenuse c missing, the formula is. c = √(a² + b²)
Answer:
13.9 (rounded)
Step-by-step explanation:
The pathaegorean theorem is A²+B²= C²
5²=25
13²= 169
169+25=194
√194=13.9

A wire is attached to the top of a tower and to a point on the ground that is 35 m from the base of the tower. If the wire makes a 65 degree angle with the ground, how long is the wire? Round your answer to the nearest tenth
Answer:
83 m
Step-by-step explanation:
The computation of the length of the wire is shown below:
Let us assume the length of the wire be x
Given that
There is 35m from the base of the tower
And, the angle with the ground is 65 degree
So, the length of the wire is
cos 65 = 35 ÷ x
x = 35 ÷ cos 65
= 83 m
There will be 6 people at Eli's cake party. You want to bake enough cake so that each person you feed will eat at least 1/5 of the cake. What is the minimum number of cakes to bake?
Please put the procedure with operations used. :(
Answer: 2 cakes.
Step-by-step explanation:
There will be a total number of 6 people at Eli's cake party.
You want that each one of these 6 people to eat at least 1/5 of a cake.
Then you need to make, at least, 6 times 1/5 of a cake.
This is equal to:
6*(1/5) of a cake = 6/5 of a cake.
And we can rewrite this as:
(6/5) of a cake = (5 + 1)/5 of a cake = (5/5 + 1/5) of a cake = 1 cake + 1/5 of a cake.
But you can not bake only 1/5 of a cake, we need whole numbers.
Then we need to round up to the next whole number, which is 2.
This means that you need to bake at least 2 cakes.
I solved it myself and my result is (n+1)/n. Why is that 1/2 there? An explanation would be great if possible. Thanks!
Answer:
The product of (k + 1) series starts with 3 (because k = 2) and you need 2 to be multiplied to this in order to get (n + 1)!
Therefore you need to multiply 2 and 1/2 to make it right. 2 completes the factorial and 1/2 remains.
Hope it was clear explanation.

FAST PLEASE!! Emma weighs half as much as Sonya. Sonya weighs 120 pounds. How much
does Emma weigh? Write the expression and solve
Answer:
I think it would be 120
Step-by-step explanation:
You add 120+120 and it would equal 240. Then 240 dived by 2 which will equal 120.
(120 + 120)= 240 dived by 2= 120 I might be wrong

You have a problem. You are running out of M&Ms (the candy). Originally, you had 200 small pieces. Last week, you got a little excited and ate 151 pieces of your original amount in one week (7 days). You are determined to last the remaining M&Ms for exactly one more week. If you eat the same amount every day, how many pieces will you be able to eat each day?
Create an equation to show how you would find the number of M&M pieces you could now have each day.
What is the answer to your equation in part 1? What steps did you take to solve your equation?
Please explain how you know your equation is correct.
Answer:
49 = 7m
m = 7
Step-by-step explanation:
200 - 151 = 49
There are 49 M&M's left
m = M&M's per day
7(7) = 49
Answer:
49 ÷ 7 = 7
Step-by-step explanation:
200 - 151 is 49 so 7 beacuase 49 divided by 7 is 7

The length of the base of an isosceles triangle is x. The length of a leg is 4x - 2. The perimeter of the triangle is 95. Find x.
Answer:
x = 11
Step-by-step explanation:
sides of triangle measure: 'x', '4x-2' and '4x-2' since isosceles means both legs are equal
perimeter is the sum of all sides, so set up equation:
95 = 4x - 2 + 4x - 2 + x
95 = 8x - 4 + x
95 = 9x - 4
99 = 9x
x = 11

a. What is the water bill if 30,000 gallons of water are used?
b. How many gallons of water can be used for the water bill to be $150.
Answer:
I'm only here cause of the pfp haha
Step-by-step explanation:
you look good if that's you
Answer:
a) $53.34
b) 84,360.9 gallons
Step-by-step explanation:
let 'x' = cost of bill for 30,000 gallons
a) i set up a proportion as follows:
$1.33/748g = x/30,000
i cross-multiplied and got $53.34
b) i set up a proportion as follows:
let 'y' = how many gallons $150 can buy
$1.33/748g = 150/y
i cross-multiplied and got 84,360.9 gallons
