this is simple. make a circle graph, with radii 6, and plot the points. If they are on the edges of the circle, they are 6 units away from origin. ive attached an image of this lol
What is the answer to this?
Answer:
132 units²
Step-by-step explanation:
The figure is a trapezoid, so its area can be found using the formula for the area of a trapezoid.
A = 1/2(b1 +b2)h
The top "base" is the difference between 21 units and 9 units, so is 12 units. Filling in the numbers, we have ...
A = 1/2(21 units +12 units)(8 units) = 132 units²
The area of the figure is 132 square units.
Question 1)
Convenience Store Your friends know that you stop at the local convenience store every morning on your way to school and get a bottle of juice. For your birthday, they get you a $50 gift card. Suppose that a small bottle of juice costs $2 and all you ever buy at the store is juice.1.(a)W rite a function, f, that can be used to track your gift card balance in terms of the number of bottles of juice, x, you have purchased.(b)What is the rate of change of this function? What does this mean for this scenario?(c)What will the graph of the function look like? How do you know?(d)What does )(=f“246” mean in the context of the problem?(e)Using the format given below, complete the table representing your function by choosing several different values representing the number of bottles of juiceyou have purchased and computing the remaining balance on your gift card. Then, use your table to construct ordered pairs of the form(xf,(x)).
Question 2)

2. Martha ran 2 miles in 15 minutes.
At this rate, how many miles
would she run in 2 hours?
Answer:
4 fifteen minute periods make up one hour, so she will run 8 miles in one hour. Since it’s 2 hours, you would multiply that by 2 to get 16. So, Martha ran 16 miles

Answer:
70 degrees
Step-by-step explanation:
2x+3x-20+x+20=180
( angles in a triangle add up to 180 degrees)
as you want to find one x you need to move everything else to the other side: first collect all the like terms: 6x=180
in order to find x you need to divide 180 by 6 which is equal to 30
therefore x=30
if you substitute this into XYZ it would be: 3(30)-20
90-20=70
therefore XYZ=70 degrees
Hope this helped
Answer:
70
Step-by-step explanation:
So we know that the angles of a triangle equal up to 180 degrees. So let's make an equation. So we can do:
2x+(3x-20)+(x+20) = 180
Simplify:
6x=180
x=30
We can also plug this in to check our work. So it would be:
60+(90-20)+(30+20)
simplify
70+50+60=180
Then we have to find angle XYZ so we do 90-20=70
Adam steps on a scale holding four bricks of equal weight. The scale reads 360 pounds. Write an equation relating Adam's weight and the weight of the bricks to the total weight shown on the scale. Use 'A' for Adam's weight and 'b' for the weight of a single brick.
Please help Image attached
Answer:
27°
Step-by-step explanation:
when you see a square to represent that angle, that means that angle is 90 degrees (a right angle)
the angle of a straight line is 180
so [tex]180-90=90[/tex]
[tex]3x+9=90[/tex]
[tex]3x=81[/tex]

Construct an isosceles triangle with one 70* angle and two 4 inch sides. Is this a unique triangle? Explain why or why not.
The isosceles triangle has 2 equal sides of 4 inches and a vertex angle measure of 70 degrees, and it is a unique triangle
How to determine if the triangle is unique?The given parameters are:
Triangle type = Isosceles triangle
Side length = 4 inches
Angle measure = 70 degrees
Since the triangle is an isosceles triangle, then the equal angles would be:
Ф = 180 - 2 * 70
Ф = 40
The length (L) of the third side is:
L/2 = 7 * cos(40)
Multiply both sides by 2
L = 14 * cos(40)
L = 10.7
So, the angles in the triangle are 70 and 40 degrees; while the side lengths are 4 and 10.7 inches
See attachment for the figure of the isosceles triangle

Answer: I would say C
Step-by-step explanation: Its not A cuz 7 is a decimal, its not B because of there being 2 p's and same for D
Answer:
D. p + 0.07p
Step-by-step explanation:
Answer choice D is correct because if we were to plug in a variable (e.g. 1 and 2), we would get the same amount when using 1.07p. All the other answer choices either work for only one value or don't work at all.
For example,
1 + 0.07(1) = 1.07(1).1 + 0.07 = 1.07
1.07 = 1.07
2 + 0.07(2) = 1.07(2)2 + 0.14 = 2.14
2.14 = 2.14

Given:
∠A = 50°In the diagram given, we can tell that:
∠A and ∠B are a linear pair.∠B and ∠C are a linear pair.This means that:
∠A + ∠B = 180°∠B + ∠C = 180°Step-1: Find ∠B.
∠A + ∠B = 180°=> 50 + ∠B = 180°=> ∠B = 180 - 50=> ∠B = 130°Step-2: Find ∠C.
∠A = ∠C (Vertically opposite angles=> ∠C = 50°∠A+∠B = 180° [Linear pair]
50+ ∠B = 180°
∠B = 180-50
∠B = 130°

YOU BE THE TEACHER. Your friend describes a sequence of rigid transformations between the figures. is your friend correct? EXPLAIN your reasoning.
Answer:
Yes, they are correct.
Step-by-step explanation:
When reflected across the x-axis, the y coordinate changes. For example, (1, -1) becomes (1, 1). When translated left 5 units, it would be (-4, 1). Since that point is true, that means the shape is in its correct place.
