∠A and \angle B∠B are supplementary angles. If m\angle A=(8x-25)^{\circ}∠A=(8x−25) ∘ and m\angle B=(7x-5)^{\circ}∠B=(7x−5) ∘ , then find the measure of \angle B∠B.
An38
Step-by-step explanation:
The measure of angle B is 93°
Here,
∠A and ∠B are supplementary angles.
∠A = (8x - 25)° and ∠B = (7x - 5)°
We have to find ∠B.
What are Supplementary angles?
Two Angles are Supplementary when they add up to 180 degrees.
Now,
∠A and ∠B are supplementary angles.
Hence, ∠A + ∠B = 180°
Here, ∠A = (8x - 25)° and ∠B = (7x - 5)°
Put in above equation we get;
(8x - 25)° + (7x - 5)° = 180°
15 x - 30 = 180
15 x = 210
x = 14
So, Measure of ∠B = (7x - 5)° is;
∠B = (7x - 5)° = ( 7 * 14 - 5) = 98 - 5 = 93°
Hence, The measure of angle B is 93°.

a 6-pack of undershirts cost $13.98 this $3.96 less than the cost of buying 6 individual shirts. if each undershirts costs the same amount, how much does each undershirts cost when purchased individually
Answer:
Each undershirt costs $2.99 when purchased individually.
Step-by-step explanation:
The problem says that $13.98 is $3.96 less than the cost of buying 6 individual shirts which means that the total cost of buying 6 individual shirts is $17.94.
To find the price of 1 individual shirt, you divide 17.94 by 6. When you do this, you get $2.99. $2.99 is the cost of each undershirt when purchased individually.

Does anyone know what the slope for C = 22.5 - (1/160)m
The slope of the linear equation, [tex]C = 22.5 - (\frac{1}{160}) m[/tex], is: [tex]-\frac{1}{160}[/tex]
Recall:
A linear equation in slope-intercept form is given as: y = mx + b."m" is the slope."b" is the y-intercept.Thus, given the linear equation:
[tex]C = 22.5 - (\frac{1}{160}) m[/tex],
C represents y
m represents x
[tex]-\frac{1}{160}[/tex] represents the slope (m)
22.5 represents b.
Therefore, the slope of the linear equation, [tex]C = 22.5 - (\frac{1}{160}) m[/tex], is: [tex]-\frac{1}{160}[/tex]

The temperature of a city doubles during the day. It then decreases by 12.1ºF after the sun goes down. The temperature at the end of the day is −6.5°F.
What was the temperature at the beginning of the day?
(This is a question on k12)
the answer is 5.6
because 5.6-12.1=-6.5 which is the temperature at the end of the day
hope this helps I really take my time to do this:)
Answer:
The answer is 2.8
Step-by-step explanation:
Since the temperature at the end of the day is -6.5.
So you add 12.1ºF to -6.5 and you get 5.6.
5.6 is the temperature throughout the day.
The question asks for the temperature from
the start of the day and the question says it
doubles throughout the day. Therefore,
divide 5.6 by 2 which gets you 2.8.

Large fluffy towels were on sale at a discount of 30%. If the sale price was $8.40, what was the original price?
Answer:
$ 12
Step-by-step explanation:
Think that, Original price of a towel is $ 100
Using the above we can create a equation like this. Let the Original price of the towel given in the question be x.
Original price Discount Sale price
100 30 70
x 8.40
Now let's make an equation like this,
[tex]\frac{100}{x} =\frac{70}{8.40}[/tex]
Use cross multiplication and solve for the x
100 × 8.40 = 70 x
[tex]840=70x[/tex]
[tex]\frac{840}{70} =\frac{70x}{70}[/tex]
[tex]x=12[/tex]
Therefore, the original price is $ 12

how to find domain and range of a function
Answer:
The domain is found depending on the information you're given. In a table, the domain is found by taking all the x values given and listing them least to greatest. Same with ordered pairs. In a graph, the domain is found by first seeing if there are any restrictions and then find the x values that work and have one output.
The range is found the same way, but with the y values.

On comparing to slope intercept form of the line ,
m = 1/2As we know that the product of slopes of two perpendicular lines is -1. Hence ,
m_perp = -2 .Given point is (1,3) . Using point slope form ,

As mentioned in the question, a loan of $4500 is given at an interest rate of 12% compounded each year.
What is compound interest?Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.
Here
(a)
The amount owed at the end of 1 year
= 4,500 × 12/100
= 540
Amount = 540+4,500
= $5,040
(b)
The amount owed at the end of 2 years
= 5,040 × 12/100
= 604.8
Amount = 5040 + 604.8
Amount = $5644.8
