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. :)

hey guys can you answer this one question real quick
Answer:
a. 1/5
b. (3, 3/5)
c. 1/5x = y
Step-by-step explanation:
Remember: (x, y)
0.5 = 1/2
(1/2, 1/10) = 1/10 ÷ 1/2 = 1/10 • 2 = 1/5, you can divide y/x = constant of proportionality. 1/10 ÷ 1/2.
1 2/5 = 7/5
(7, 7/5) = 7/5 ÷ 7 = 7/5 • 1/7 = 1/5, y/x = constant of proportionality. 7/5 ÷ 7.
a. 1/5 is the constant of proportionalityb. (3, 3/5) because 3/5 ÷ 3 or 3/5 • 1/3 = 1/5.c. 1/5x = yplease help!! will give brainliest

What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The trinomial is given below.
⇒ 4x² + 12x + 9
Then the factor of the trinomial will be
⇒ 4x² + 12x + 9
⇒ 4x² + 6x + 6x + 9
⇒ 2x(2x + 3) + 3(2x + 3)
⇒ (2x + 3)(2x + 3)
⇒ (2x + 3)²
Then the correct option is D.

Step-by-step explanation:
14. On March 1 Tessa Obee deposited her IRS refund check for $9,364.85 in a savings account at State Bank. The account pays 4 percent interest calculated on a daily basis. Five days later on March 6 she withdrew $1,000.00. On March 18, 12 days later, she withdrew $2,000.00. On March 28, 10 days later, she withdrew another $2,000.00. Three days later on March 31 interest was computed. How much simple interest did her money earn?
Answer:
Her money earned a simple interest of $24.55.
Step-by-step explanation:
Since Tessa deposited $9364.85 and she gets 4% interest on daily basis, then before she withdraws $1000 after 5 days, she must've gotten an interest of:
9364.85 x 4% × (5/365) ≈ 5.13
After withdrawing $1000, she has $8364.85. If this remains in the account for 12days, as we have in the question, then the interest on that will be:
8364.85 x 4% × (12/365) ≈ 11.00
After withdrawing $2000, she has $6364.85. If this remains for 10days, her interest would be:
6364.85 x 4% × (10/365) ≈ 6.98
After withdrawing $2000, she has $4364.85. If this remains for 3days, her interest would be:
4364.85 x 4% × (3/365) ≈ 1.44.
In totality, her interest would be: 5.13 + 11.00 + 6.98 + 1.44 = 24.55.
Hence, her money earned a simple interest of $24.55.

1.The growth of a sample of bacteria can be modeled by the function b(t)=100(1.06)t where b is the number of bacteria and t is time in hours.
What is the number of total bacteria after 3 hours?
Given:
The growth of a sample of bacteria can be modeled by the function
[tex]b(t)=100(1.06)^t[/tex]
where, b is the number of bacteria and t is time in hours.
To find:
The number of total bacteria after 3 hours.
Solution:
We have,
[tex]b(t)=100(1.06)^t[/tex]
Here, b(t) number of total bacteria after t hours.
Substitute t=3 in the given function, to find the number of total bacteria after 3 hours.
[tex]b(t)=100(1.06)^3[/tex]
[tex]b(t)=100(1.191016)[/tex]
[tex]b(t)=119.1016 [/tex]
Therefore, the number of total bacteria after 3 hours is 119.1016.
Two cars travel at the same distance. The first car travel at 50 miles per hour and reaches its destination at t hours. The second car travels at a rate of 60 miles per hour and reaches its destination 1 hour earlier than the first car how long does it take for the first car to reach its destination
Answer:
The first car reaches its destination in 6 hours.
Step-by-step explanation:
Speed of the first car = 50 miles per hour
Time taken = t hours
Distance travelled = Speed × Time = 50 t
Speed of the second car = 60 miles per hour
Time taken = [tex](t-1)[/tex] hours
Distance travelled = Speed × Time = [tex]60(t-1)[/tex]
As two cars travel the same distance,
[tex]50t=60(t-1)\\50t=60t-60\\60=60t-50t\\60=10t\\t=\frac{60}{10}\\t=6[/tex]
So, the first car reaches its destination in 6 hours.
It would take the first car 6 hours to reach its destination.
Speed is the ratio of distance to time. It is given by:
Speed = distance /time
Since the two cars travel at the same distance, let d represent this distance.
The first car travel at 50 miles per hour and reaches its destination at t hours. Hence:
50 = d / t
d = 50t (1)
The second car travels at a rate of 60 miles per hour and reaches its destination 1 hour earlier than the first car. Hence the time = t - 1. Hence:
60 = d / (t - 1)
d = 60(t - 1)
d = 60t - 60 (2)
Equating both equations gives:
50t = 60t - 60
10t = 60
t = 6 hours
Hence it would take the first car 6 hours to reach its destination
