Mariah worked for 3 hours and earned a total of $28.50. Which equation can be used to find r the amount of money Mariah earns per hour.
Answer:
28.50/3=r
Step-by-step explanation:
Answer:
28.50 divided by 3.
Step-by-step explanation:
This is because if 28.50 is the total and we know she worked for 3 hours that means that the answer to our equation: 9.5 means that each hour she worked for she was given 9.50 or 9.5 dollars. We can check this by doing 9.5 x 3 which gives us 28.5 or 28.50. :)

Composite figure composed of a a right triangle with a base of 3 mm and a height of 4 mm, and two rectangles, one with side lengths of 3mm and 4mm, the other with side lengths of 1 mm and 6 mm.
Answer:
18 mm²
Step-by-step explanation:
Firstly, I do not think the person above me has the correct answer.
Okay, so I am not very good at explaining things but I will try. When finding the area of a composite figure, you add Area A + Area B.
So for this equation, figure one has a length of 4mm and a width of 3mm. Remember when we are finding the area of a shape, we multiply Length times Width. So, figure one has an area of twelve. The Same applies to figure two. Figure two has a length of 1mm and a width of 6mm, we multiply one by six and get six. Now we add the area of the twelve and six and we get 18mm²
I understand that my explaining skills suck, so I will show it in an easier way
Area A = 4mm x 3mm
Area A = 12mm
Area B = 1mm x 6mm
Area B = 6mm
Area A + Area B = Total Area
12mm + 6mm = 18mm²
So, 18mm² will be your answer.
I hope this helps.
Sorry if it isn't helpful or correct.

as shown, several parallelograms are formed in an expandable gate. The angles of the parallelograms change as the gate is expanded and compressed. Find m
Answer:
m = 145
Step-by-step explanation:
All angles inside a parallelogram = 360
∠ABC = ∠ADC
35 = ∠ADC
360 = 2(∠ABC) + 2( ∠DAB)
360 = 70 + 2( ∠DAB)
290 = 2( ∠DAB)
145 = ∠DAB
The adjacent angle of the parallelogram are supplementary angles. If the angle ∠ABC is 35°. Then the angle ∠DAB will be 145°.
What is a parallelogram?It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides and angles are parallel and equal.
In the parallelogram ABCD, the angle ∠ABC is 35°.
We know that adjacent angle of the parallelogram are supplementary angles.
∠ABC + ∠DAB = 180°
35° + ∠DAB = 180°
∠DAB = 180° – 35°
∠DAB = 145°

On a coordinate plane, a line goes through (negative 8, 4) and (8, 4). A point is at (negative 4, negative 6).
What is the equation of the line that is parallel to the given line and passes through the point (−4,−6 )?
x = −6
x = −4
y = −6
y = −4
Answer:
The equation of parallel line passes through the point (−4,−6 ) is:
y = -6
Please also check the attached graph.
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven that on a coordinate plane passes through (-8, 4) and (8, 4).
As the value of y remains the same for any value of x.
i.e. y = 4 for any value of x.
Thus, the given line is a horizontal line.
We know that the slope of a horizontal line is zero.
Also it is clear that at x = 0, the value of y = 4. In other words, we can observe that the y-intercept b = 4.
so substitutig m = 0 and b = 4 in the slope-intercept form
y = mx + b
y = 0x + 4
y = 4
Therefore, the equation of line passing through the point (-8, 4) and (8, 4) is:
y = 4
Now, we also know that the slope of parallel lines is equal.
Thus, the slope of the line parallel to the line y = 4 is also 0.
As the parallel line passes through (−4,−6 ).
so substituting m = 0 and (-4, -6) in the slope-intercept form of line equation to determine the y-intercept b
y = mx + b
(-6) = 0(-4) + b
-6 = 0 + b
switching the sides
0 + b = -6
b = -6
Thus, the slope-intercept b = -6
now substituting m = 0 and b = -6 in the slope-intercept form of line equation
y = mx + b
y = 0(x) + -6
y = 0 - 6
y = -6
Therefore, the equation of parallel line passes through the point (−4,−6 ) is:
y = -6

Marlin obtains a 20/6 balloon mortgage to finance $305,500 at 5.75%. How much principal and interest will he have already paid when his
balloon payment is due?
$188,267.86
$152,285.77
$154,430.64
$249,256.48
Answer:
$154,430.64
Step-by-step explanation:
The first step is for us to determine the monthly payment as follows:
Mortgage amount can be found as the present value of all monthly payments, hence, using the formula below we can determine monthly payment as follows:
mortgage amount=monthly payment*(1-(1+r)^-n/r
mortgage amount=$305,500
monthly payment is unknown
r=monthly interest rate=5.75%/12=0.4791667%
n=number of monthly payments in 20years=20*12=240
305,500=monthly payment*(1-(1+0.4791667% )^-240/0.4791667%
305,500=monthly payment*(1-0.31750756 )/0.0047916670
305,500=monthly payment*0.68249244 /0.0047916670
monthly payment=305,500*0.0047916670 /0.68249244
monthly payment=$2,144.87
Number of months that payments have been made=6*12=72
total paid=$2,144.87*72
total paid for 6 years=$ 154,430.64

A hot air balloon is descending at a rate of 287 feet per minute.
Find the total change in elevation of the balloon in 4 minutes.
Answer:
Please check the explanation.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-interceptA hot air balloon is descending at a rate of 287 feet per minute.
Thus, the rate of change m = -287
The negative sign indicates that a hot air balloon is descending.
Let y be elevation.
Let x be the time (in minutes)
As there is no mentioning of the initial height.
Thus, the y-intercept b = 0
now substituting m = -287 and b = 0
y = mx + b
y = -287x + 0
y = -287x
In order to determine the total change in elevation of the balloon in 4 minutes, we need to substitute x = 4 in the equation y = -287x.
Thus, the total change in elevation of the balloon in 4 minutes will be:
y = -287x
y = -287(4)
y = -1148 feet
The negative sign indicates that that the elevation is decreasing.
