Find the exterior angle measure:
Answer:
59 degrees
Step-by-step explanation:
The total amount of degrees for a triangle must add up to 180 degrees.
74 + 47 = 121
180 - 121 = 59
Thus meaning the missing exterior angle measure is 59 degrees.

A 3-gallon container of window cleaner costs $30.72. What is the price per quart?
Answer: The answer to your question is: 1 quart = $2.56
Step-by-step explanation: data
3-gallon cost = $30.72
cost of 1 quart = 2.56
Rule of three
1 gallon --------------- 4 quarts
3 gallons --------------- x
x = 12 quarts
12 quarts --------------- $30.72
1 quart ---------------- x
x = 1x 30.72 / 12 = $ 2.56
Use scientific notation to estimate the number of inches in 1,225 miles. Include all calculations in your final answer. 1 inch =1578x 10-5 miles
Answer: (7.129)*10^(7) inches.
Step-by-step explanation:
We know that:
1 inch = 1.578*10^(-5) miles.
If we divide both sides by 1.578*10^(-5), we get:
(1/1.578*10^(-5)) inches = 1 mile
63,371.36 inches = 1 mile
Now, we have 1,225 miles, this is equal to 1,125 times 63,371.36 inches
Then 1,225 miles writen in inches is:
1,125*(63,371.36 inches) = 71,292,780 inches.
Now, to write this in scientific notation, we need to count the number of decimals between the first one at the left, and the decimal point.
In this case we have 7 decimals.
Now, let's take the first 4 decimals, (7129) and write a decimal point after the first one:
(7.129)
Now let's multiply this by then to the power of 7 (where 7 is the number of decimals we found above).
Then the scientific notation of 71,292,780 inches. is:
(7.129)*10^(7) inches.

Which of the following correctly uses absolute value to show the distance between −70 and 13? (5 points)
−70 − 13| = |−83| = −83 units
|−70 − 13| = |−83| = 83 units
|−70 + 13| = |−57| = 57 units
|−70 + 13| = |−57| = −57 units
Answer:
|−70 − 15| = |−85| = 85 units - B
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
First of all, distance cannot be negative so you eliminate answers A and D immediately.
Now to find the distance between a negative number and a positive number, you either have to take the absolute value of the negative number (to turn it positive) and add it to the positive or take the absolute value of the positive number subtracted by the negative number.
Basically, you're doing this because it compensates for the distance between the negative number and 0.
The only answer choice that is consistent with these terms is B.

How do i turn a line graph into a equation
Answer:
Read lol.
Step-by-step explanation:
Ok for example with the graph below. You want to find the slope. The slope of this graph is 4/5, because I did the technique rise over run. You want to find a point on the line that is in the middle of a square and then find another point and measure. Go up until it meets the other and then go left or right depending on the direction of the line.
After you find the slope you want to find the y-intercept. To find the y-intercept take any point on the line and plug it into this formula with the slope: y=mx+b
So I took the point (0,3): 3=(4/5)(0)+b
Solve: 3=0+b
3=b
And then wen u have all the right material for your equation, you can plug it all in, which gets me: y=4/5x+3

Determine if the following triangle is a right triangle or not using the Pythagorean Theorem Converse. Triangle with side lengths of: 10 m, 8 m, and 14 m
False, these measures do not form a right triangle.
True, these measures do form a right triangle.
Answer:
False
Step-by-step explanation:
[tex]{a}^{2} + {b}^{2} = {c}^{2} \\ {10}^{2} + {8}^{2} = {14}^{2} \\ 100 + 64 = 196 \\ 164 < 196[/tex]

5/4 ÷ 3/8(s) = x
Step-by-step explanation:
Answer:
Step-by-step explanation:
How many 3/8 are in 5/4? We can set this number as x. Therre are x number of 3/8 that make up 5/4:
Therefore the PART A is: x* 3/8 = 5/4
On the other hand, 5/4 / 3/8 = x (this is just the reverse of what I mentioned earlier)

Explain how the unit rate and slope of a proportional relationship are related to each other
The relationship between unit rate and slope can be found by forming the equation of a straight line.
How to find the proportional relation between two quantities?The two quantities are said to be proportional when the ratio of each of their values are equal.
It can be of two type direct or indirect.
For direct relation the ratio is greater than one for indirect it is less than one.
The example to explain the given case is as follows,
The price and number of pens are proportional to each other.
Suppose the cost of y pens be x.
And, the cost for each pen is m.
Then, the cost for each pen can also be found by the ratio as,
m = y/x
=> y = mx
Which represents a straight line having slope m.
Thus, the unit rate and slope are the equivalent things.
Hence, the unit rate and slope of a proportional relationship are related through the equation of a straight line.

Jessica loves the smell of candles in her home. She bought a candle, and it burns down at the rate of 0.5 inches per hour. The original height
of the candle was 9 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning
For example, the point (0.9) would represent a height of 9 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)
(0.9),(__),(__),(__),(__),(__),(__)
Part B: Is this relation a function? Yes or no? Justify your answer using the list of ordered pairs you created in Part A. (2 points)
Part C: If the rate at which the candle burned was 0.45 inches per hour instead of 0.5 inches per hour, would the relation be a function? Yes or
no? Explain your answer using input and output values.
Step-by-step explanation:
Original height is the initial value, burn down rate is 0.5 inches per hour
This would be represented by a function:
y = 9 - 0.5xPart AOrdered pairs:
(0, 9), (1, 8.5), (2, 8), (3, 7.5), (4, 7), (5, 6.5), (6, 6)Part BRate of burn down is stable at 0.5 inches, this is a functionPart CIf the rate at which the candle burned was 0.45 inches per hour instead of 0.5 inches per hour, the relation would still be a function. The output values would have same difference of 0.45 inches and the function would be:

Answer: He will practice both on every 15 days.
Step-by-step explanation:
Given: Jaquan practices soccer every 3 days.
He practices basketball every 5 days Jaquan practiced both today.
The number of days until he practices both = Least common multiple of 3 and 5
= 3 x 5 [Both are primes]
= 15
Hence, he will practice both on every 15 days.
Least common multiple of two numbers p and q is the smallest number that is divisible by both p and q.

A BMX show has
416
people in attendance. If
312
attendees are under the age of
35
,
what is the ratio of attendees under the age of
35
to attendees
35
and older?
Answer:
The ratio is 3 : 1.
Step-by-step explanation:
Given that:
Number of attendees in the show = 416
Number of people under 35 = 312
Number of people 35 and older = 416 - 312 = 104
Ratio of attendees under 35 to attendees 35 and older
Attendees under 35 : Attendees 35 and older
312 : 104
3 : 1
Hence,
The ratio is 3 : 1.
