Answer:
Angle 1 = 40
Step-by-step explanation:
Angle 1 and Angle 2 are alternate angles. So,
2x + 20 = 3x + 10
3x - 2x = 20 - 10
x = 10
Angle 1 = 2x + 20 = 2 x 10 + 20 = 40

Answers
Answer: 75%
Step-by-step explanation:
First: work out the difference (decrease) between the two numbers you are comparing.
Decrease = Original Number - New Number
Then: divide the decrease by the original number and multiply the answer by 100.
% Decrease = Decrease ÷ Original Number × 100
Decrease =240- 60
Decrease = 180
180 /240=0.75 * 100 = 75%
The percent of decrease = 75%

If the Volume of a Cylinder is 25*pi* and the radius is 4, what is the height "h"?
Round your answer to the nearest tenth if needed.
Answers
Answer:
The height of the cylinder is 0.497.
Step-by-step explanation:
Given that the Volume of a cylinder is 25 and the radius is 4, to determine what is the height of said figure, the following calculation must be performed, knowing that the volume of a cylinder is calculated using the following formula (3.14 x r^2 x h = X):
3.14 x (4x4) x h = 25
3.14 x 16 x h = 25
50.24 x h = 25
h = 25 / 50.24
h = 0.497
Therefore, the height of the cylinder is 0.497.

Suppose you invest, every month, in an annuity that pays 3% interest, compounded monthly. After 25 years, you have $550,000. How much money do you earn from interest? Round your answer to the nearest hundred dollars. Do NOT round until you have calculated the final answer.
Answers
Answer:
180100
Step-by-step explanation:
Use savings annuity formula
Substitute A(25) = $550,000 , R= 0.03 and N=12 simplify and solve for D.
You have earned 292589 dollars from compound interest.
What is compound interest ?Compound interest is calculated from both the initial principle and the previous accumulated interest.
According to the given question you invest, every month, in an annuity that pays 3% interest.So r = 3.
After 25 years, you have 550,000 dollars so amount (A) = 550,000.
We know, Interest = Amount - Principle.
A = P(1 + r/100)ⁿ, where n represents time in years.
Given n = 25.
The interest is compounded monthly so the formula will be
A = P[1 + (r/12)/100]¹²ⁿ.
555000 = P[ 1 + 3/1200]¹²ˣ²⁵.
555000 = P[ 1203/1200]³⁰⁰.
555000 = P(1.0025)³⁰⁰.
555000 = 2.115P
P = 262411.
CI = ( 555000 - 262411) dollars.
CI = 292589 dollars.

Answers
Answer:
Look at my explanation
Step-by-step explanation:
The circumference of a circle is 2πr, so you can set it up like this since the circumference was 22π.
2πr = 22π
divide both sides by 2
πr = 11π
divide both sides by π
you get r = 11
So your radius is 11.
To find the area, you must do πr^2 ("^2" means squared)
if you substitute 11 for r you get
11π^2
you can do 11 squared first
11^2 = 121
the area of the circle = 121π
Keep in mind that they said to use 3.14 for π
so you can do 121 x 3.14

Points A and B are on opposite sides of the Grand Canyon. Point C is 200 yards from A. Angle B
measures 87° and angle C measures 67º. What is the distance between A and B? Round answer to
nearest tenth.
Answers
Answer:
AB = 184.4 yards
Step-by-step explanation:
The description here gives a triangle with two angles and a side. Let the distance between A and B be represented by d. Thus applying the Sine rule, we have;
[tex]\frac{a}{Sin A}[/tex] = [tex]\frac{b}{Sin B}[/tex]
[tex]\frac{200}{Sin 87}[/tex] = [tex]\frac{d}{Sin 67}[/tex]
d = [tex]\frac{200*Sin 67}{Sin 87}[/tex]
= [tex]\frac{200*0.9205}{0.99863}[/tex]
d = 184.3526
Thus, the distance between points A and B is 184.4 yards

You borrow $600 to buy a canoe. The simple annual interest rate is 5%. You pay off the loan after 4 years of equal monthly payments. How much is each payment?
Answers
Answer:
Amount of each payment = $15 each month
Step-by-step explanation:
Given:
Amount borrow = $600
Simple rate = 5% = 0.05
Number of year = 4 year
Payment method = monthly payment
Find:
Amount of each payment
Computation:
Total amount after 4 year = P + PRT
Total amount after 4 year = 600 + (600)(4)(0.05)
Total amount after 4 year = 600 + 120
Total amount after 4 year = $720
Number of total month = 4 x 12
Number of total month = 48
Amount of each payment = Total amount after 4 year / Number of total month
Amount of each payment = $720 / 48
Amount of each payment = $15 each month

Hello!
This is just a conceptual problem where you'll be converting units.
If her semitrailer is 3.5m high and the bottom of the bridge (how tall the support beam are) is 11ft 9in high, we'll need to convert them into the same units and then compare both values.
Let's convert from inches to meters.
Since there are 12 inches in a feet, we can convert 11 feet into 132 inches, meaning that the bottom of the bridge is at 141 inches.
In 1 meter, there is around 39.37 inches, so we'll be dividing 141 by 39.37, giving us a number of around 3.5814, meaning that the bottom of the bridge is higher than the height of the semitrailer, and her vehicle will fit under the bridge.
Hope this helps!
