An angle measures 70.2° more than the measure of its complementary angle. What is the measure of each angle?
A complementary angle of another angle is the angle that when you add it to that angle, you get 90 degrees.
For example, we have angle A. When we add the complementary angle of angle A, you get 90 degrees. :)
So, what we can do for this problem is create an equation! :)
x + 70.2° = "an angle"
x = complementary angle
Notice: I put the 70.2° to show the difference between the complementary angle and the angle itself.
Now, we can make an equation!
(x + 70.2°) + x = 90
2x = 19.8
x = 19.8/2
x = 9.9 degrees
One angle is 9.9 degrees, and the other angle is x + 70.2 = 9.9 + 70.2 = 80.1 degrees. We can see that when we add 9.9 and 80.1 we get 90 degrees, and when you minus 9.9 from 80.1, you get 70.2. :)
Ask any questions if you need. :)

Answer:
27 feet squared
Step-by-step explanation:
the formula for the area of a triangle is b(h)/2 so u just plug in the numbers into the formula from the question. we know that the base is 6ft long and the height is 9ft long.
A = b(h)/2
A = 6(9)/2
A = 27
therefore the area of the sail is 27 feet squared.

Answer:
The whole series is:
3, 22/7, 23/7, 24/7, 25/7, 26/7, 27/7, 4
Step-by-step explanation:
Inserting Numbers Between Two Given Endpoints
Suppose we want to insert n equally-spaced numbers inside a given interval with endpoints [x,y].
To place n numbers, we need to open n+1 slots, at the end of which, a new number will be placed. The given interval is then divided into n+1 rational numbers of a value (y-x)/(n+1) each.
For example, let's add 6 rational numbers between 3 and 4. The width of the given interval is 4-3=1, and we need to place 6 numbers separated by 1/(6+1) = 1/7.
Start by the left endpoint:
3
The first number to add is 3+1/7=22/7
22/7
The second number to add is 22/7+1/7=23/7
23/7
The third number is 23/7+1/7=24/7
24/7
The next numbers follow the same pattern:
25/7
26/7
27/7
The last number is 28/7=4
4
The whole series is:
3, 22/7, 23/7, 24/7, 25/7, 26/7, 27/7, 4
We have inserted 6 rational numbers between 3 and 4.
Sue used to have a square garage with 286 ft squared of floor space. He recently built an addition to it. The garage is still a square, but now it has 50% more floor space. What was the length of one side of the garage originally? What is the length of one side of the garage now? What was the percent increase in the length of one side?
Answer:
New Length = 20.71 feet
Original Length = 16.91 feet
22.47%
Step-by-step explanation:
Original area of the square garage = 286 ft squared
Addition of 50% more space
New area of the garage = 286 + .50(286)
= 286 + 143
= 429 square feet
What was the length of one side of the garage originally?
Original area of the square garage = 286 ft squared
Area of a square = length^2
286 = length^2
Find the square root of both sides
√286 = √length^2
Original Length = 16.91 feet
What is the length of one side of the garage now?
New area of the garage = 429 square feet
Area of a square = length^2
429 = length^2
Find the square root of both sides
√429 = √length^2
New Length = 20.71 feet
What was the percent increase in the length of one side?
(New length - old length) / old length × 100
= (20.71 feet - 16.91 feet) / 16.91 feet × 100
= 3.8 feet / 16.91 feet × 100
= 0.2247 × 100
= 22.47%
The dance team traveled to a competition and traveled in two vans. The first van transported 2 adults and 5 students and cost $77. The second van transported 2 adults and 7 students and cost $95. Find the cost for one student to enter the competition.
Answer: $9
Step-by-step explanation:
Let the cost for adults be a
Let the cost for students be b.
The first van transported 2 adults and 5 students and cost $77. This will be:
2a + 5b = $77
The second van transported 2 adults and 7 students and cost $95. This will be:
2a + 7b = $95
2a + 5b = 77 ...... equation i
2a + 7b = 95 ........ equation ii
Subtract equation ii from I
-2b = -18
b = 18/2
b = $9
An student cost $9
Put the value of b into equation i
2a + 5b = 77
2a + 5(9) = 77
2a + 45 = 77
2a = 77 - 45
2a = 32
a = 32/2
a = 16
An adult costs $16

Answer:
25 [tex]\frac{5}{11}[/tex]
Step-by-step explanation:
This is the answer because:
1) You have to convert 3 [tex]\frac{7}{11}[/tex] to an improper fraction. You can do this by multiplying 11 and 3 (the denominator and the whole number) then add 7 (the numerator). This equals to [tex]\frac{40}{11}[/tex].
2) [tex]\frac{40}{11}[/tex] x [tex]\frac{7}{1}[/tex] = [tex]\frac{280}{11}[/tex]
3) Finally. convert [tex]\frac{280}{11}[/tex] to an mixed fraction which is 25 [tex]\frac{5}{11}[/tex]
Therefore, the answer is 25 [tex]\frac{5}{11}[/tex]

Write the equation of the line through the points (-3, 9) and (4, 2) in POINT-SLOPE FORM
Answer:
y-9=-1(x+3)
Step-by-step explanation:
The formula for point slope is y2-y1=m(x2-x1). So, we can use the values of the given points to solve the equation for m, or, the slope. We get an equation with the result of 2-9=m(4+3), which gives us the slope as -1. Now, substitute your xy values back in, to get the equation

The voltage V required for a circuit is given by [tex]v=\sqrt{PR}[/tex] , where P is the power in watts and R is the resistance in ohms.
How many more volts are needed to light a 100-watt light bulb than a 75-watt light bulb if the resistance of both is 110 ohms? Round answer to the nearest tenth.
Answer:
✓11000-✓8250=~ 14 volts
Step-by-step explanation:
the answer is the difference by 100-watt light bulb to a 75 light bulb.
so, all you have to do is this:
v1-v2--------> ✓PR-✓P2R2
so you'll have ✓100.110-✓75.110= ✓11000-✓8250= 14

Americans spend an average of 3 hours per day online. If the standard deviation is 32 minutes, find the range in which at least 88.89% of the data will lie. Use Chebyshev's theorem. Hint: You should memorize that when k is 2, it is 75% and when k is 3 it is 88.89%. Also convert hours to minutes and state your answer in minutes.
Answer:
84 minutes to 276 minutes
Step-by-step explanation:
Chebyshev's theorem states that:
At least 3/4(75% ) of data falls within 2 standard deviation from the mean - that means between μ - 2σ and μ + 2σ
At least 8/9(88.89)% of data falls within 3 standard deviations from the mean - between μ – 3σ and μ + 3σ .
Where k > 1 , 1 - 1/k²
k is 2, it is 75% and when k is 3 it is 88.89%
Americans spend an average of 3 hours per day online. If the standard deviation is 32 minutes, find the range in which at least 88.89% of the data will lies
Step 1
Convert 3 hours to minutes
1 hour = 60 minutes
3 hours = x
Cross Multiply
= 3hours × 60 minutes/1 hour
= 180 minutes
We know from Chebyshev's theorem that:
At least 8/9(88.89)% of data falls within 3 standard deviations from the mean - between μ – 3σ and μ + 3σ .
Hence
μ = 180 minutes, σ =32 minutes
μ – 3σ
= 180 - 3(32)
= 180 - 96
= 84 minutes
μ + 3σ
= 180 + 3(32)
= 180 + 96
= 276 minutes
Therefore the range in which at least 88.89% of the data will lie is 84 minutes to 276 minutes
