Answer:
1080 degrees
Step-by-step explanation:
The sum of the interior angles of any polygon is:
Sum = (n - 2) * 180
Where n represents the number of vertices of the polygon
This polygon has 8 vertices so:
(8-2) * 180 = 6*180 = 1080 degrees

Susan made $357 for 17 hours of work.
At the same rate, how much would she make for 9 hours of work?
Answers
Answer:
$189
Step-by-step explanation:
first, divide 357/17 to find the unit rate, which is $21/hour, then multiply 21*9 to find how much she would make in 9 hours. 21*9 = 189, so she would make $189.

Tyler's father is a used car salesman. He receives 5% commission for every car he sells. How much commission does he earn if he sells a car for $22,000?
Group of answer choices
Answers
Answer:
£1100
Step-by-step explanation:
10% of 22000=2200
2200/2=5%=1100
An easy way of finding a percentage of any number is simply moving the decimal one to the left.
Ex. 22000 =2200.0
You move it one to the left you will be given 10% of the number. If you move it one more to the left you will be given 1% of the number.
Ex. 2200.0 = 220.00
Since you only need to find 5% you can just divide the 10% in half and you can find 5% of 22000.
Work-
22,000
2200.0
2200/2 =

Slope has x at the end and the intercept doesn’t.
Answer:
The answer is a.
Step-by-step explanation:
The equation formula is y=mx+b. M stands for the slope. B stands for the y-intercept. In the question, it says that your slope is 3/8 and that your y-intercept is -2. Remember, if it says (0, -2), and 0 is your x-coordinate, it means that it is a y-intercept. So, plug in the numbers into the formula and the equation should be: y=3/8x-2

Step-by-step explanation:
we have one large rectangle and 2 small right-angled triangles to add.
the area of the rectangle is easy : 15×25 = 375
the right-angled triangle on the long side has one side = 5, and the "invisible" side is 25 - 12 - 5 = 8.
these 2 sides are hitting each other in a right angle and can therefore be used as baseline and height of the triangle.
the area of a triangle is baseline×height/2.
so, the area of the this triangle is 8×5/2 = 20.
the right-angled triangle on the right short side has one side = 5, and the "invisible" side is 15 - 10 = 5.
these 2 sides are hitting each other in a right angle and can therefore be used as baseline and height of the triangle.
so, the area of the this triangle is 5×5/2 = 12.5.
so the total area is
375 + 20 + 12.5 = 407.5

Step-by-step explanation:
since we know that our x=0 then y=3(-13)^0

put it in mind that during the indices we learnt that any number to the power zero is 1 and any number to the power 1 it is the number itself so we can continue to say
y=3(1)
=3
