Calculate the size of angle CAG.
Answer:
m(∠CAG) = 35°
Step-by-step explanation:
From the figure attached,
Apply Pythagoras theorem in ΔCAG,
Length of AC = [tex]\sqrt{(27)^2+(36)^2}[/tex]
= [tex]\sqrt{729+1296}[/tex]
= [tex]\sqrt{2025}[/tex]
= 45
Now find the tangent of the given angle CAG,
tan(∠CAG) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{CG}{AC}[/tex]
m(∠CAG) = [tex]\text{tan}^{-1}(\frac{31.5}{45} )[/tex]
= [tex]\text{tan}^{-1}(0.7)[/tex]
= 34.992°
≈ 35°

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.

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.

Molly has enough paint to cover an area of 250 ft.² she wants to paint to walls the rectangle or wall is 8 feet high and 30 feet wide the square wall has a height of 9 feet does Molly have enough paint to cover the area of both walls?
Answer:
Step-by-step explanation:
Area of rectangle = length x width
Area of square = side x side
Given: Dimension of rectangular wall: 8 feet high and 30 feet wide
Area of rectangular wall = 8 feet x 30 feet = 240 ft²
Height of square wall = 9 feet
Area of square wall = 9 x 9 ft² = 81 ft²
Total area need to paint = 240 ft²+ 81 ft² = 321 ft² > 250 ft.²
i.e. Molly does not have enough p[aint to cover both walls.

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.

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:
y = 9 - 0.45xThe school that Kathryn goes to is selling tickets to a spring musical. On the first day
of ticket sales the school sold 12 senior citizen tickets and 14 student tickets for a total
of $132. The school took in $108 on the second day by selling 12 senior citizen tickets
and 10 student tickets. What is the price each of one senior citizen ticket and one
student ticket?
Answer:
Senior citizen ticket = $4, student ticket = $6
Step-by-step explanation:
To do this, form a system of equations where x = the cost for a senior citizen ticket and y = the cost for a student ticket.
Since 12 senior citizen tickets and 14 students tickets cost $132, you get
12x + 14y = 132.
Since 12 senior citizen tickets and 10 students tickets cost $108, you get
12x + 10y = 108.
You can subtract those two equations, so
12x + 14y = 132
-(12x + 10y = 108)
and you get
4y = 24
divide both sides by 4
y = 6
substituting into the equation 12x + 10y = 108,
12x + 10(6) = 108
12x + 60 = 108
subtract 60 from both sides
12x = 48
divide both sides by 12
x = 4
A senior citizen ticket costs $4 and a student ticket costs $6.
Briana buys a reel of thread for sewing. Th ere are 10 m of thread on the real. Her brother in grade 4 used 210 cm. How much is left on the reel in centimeters?
Answer:
790cm
Step-by-step explanation:
Briana buys a reel of thread for sewing. There are 10 m of thread on the real. Her brother in grade 4 used 210 cm. How much is left on the reel in centimeters?
1m = 100cm
10m = x
x = 10 × 100cm
x = 1000cm
The total number of thread on the reel = 1000cm
The amount of thread left on the reel is calculated as:
The total number of thread on the reel - The amount of thread on the reel that was used.
= 1000cm - 210cm
= 790cm

The image of the point (-1, -1)(under a translation is (4, 4)( Find the coordinates of the image of the point (-6, 5) under the same translation.
The coordinates are (-1, 10).
What is translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions. Since it is just moving of the shape from one place to other, there is no change in the shape.
Translation is one of the transformations in math. When a shape has been transformed, the original shape is called the preimage and the vertices are usually labeled using uppercase letters (Example: ABCD). The translated shape is called the image and the vertices are labeled using uppercase letters with a “prime” next to each (Example: A′B′C′D′, and is pronounced “A-prime, B-prime, C-prime, D-prime”).
Given:
the point is (-8, 3) whose image point is (-5, 2)
The difference between the coordinates of the image and the coordinates of the original is the same for both points.
X - (-6, 5) = (4, 4) -(-1, -1)
X = (4, 4) -(-1, -1) +(-6, 5) = (4+1-6, 4+1+5)
X = (-1, 10)
Hence, the point is (-1, 10)
