Answer:
∠A = 148°
∠B = 32°
Step-by-step explanation:
We know that ∠A and ∠B are supplementary angles, this means that:
∠A + ∠B = 180°
And we also know that:
∠A = (7x + 15)°
∠B = (x + 13)°
Then we have a system of 3 equations.
To solve it, we can replace the second and third equations into the first one, and get:
(7x + 15)° + (x + 13)° = 180°
Now we can solve this for x, but first, let's remove the degree sign so it is easier to work:
7x + 15 + x + 13 = 180
(7 + 1)*x + 28 = 180
8*x = 180 - 28 = 152
x = 152/8 = 19
Now that we know x, we can find the values of ∠A and ∠B
∠A = (7x + 15)° = (7*19 + 15)° = 148°
∠B = (x + 13)° = (19 + 13)° = 32°
Which of the following statements is true?
A. 2/8 is between 5 and 6
B. 765 is between 6 and 7
c. 5/3 is between 9 and 10
D. 3,/5 is between 12 and 13

Find the ratio (red to blue) of the perimeters of the similar triangles. Write your answer in simplest form.
Answer:
[tex] \frac{12}{7} [/tex]
Step-by-step explanation:
Side length of red ∆ = 12
Side length of blue ∆ = 7
Given that the red ∆ is similar to the blue ∆, therefore the ratio of their corresponding sides = the ratio of their perimeter.
The ratio of the perimeter of red ∆ to perimeter of blue ∆ = side length of red ∆ / side length of blue ∆
[tex] = \frac{12}{7} [/tex]
The ratio (red to blue) of the perimeters of the similar triangles is 12:7
Assuming that the similar triangles are equilateral triangles, then all their sides will be equal.
Perimeter of a triangle = s1 + s2 + s3
For the red triangle;
Perimeter of the red triangle = 12 + 12 + 12
Perimeter of the red triangle = 36
For the blue triangle:
Perimeter of the blue triangle = 7 + 7 + 7
Perimeter of the blue triangle = 21
Taking the ratio of their perimeters;
Ratio of red to blue = 36:21 = 12:7
Hence the ratio (red to blue) of the perimeters of the similar triangles is 12:7

|x|=9
Answer:
9 or -9
Step-by-step explanation:
the lines surrounding x are absolute value, which gets rid of negative and positives and simply ask the distance from x on a number line if the absolute value of x is 9, then x is 9 places away from 0 on the number line, so it could be 9 or -9

Write the equation of a parabola with directrix y=8 and focus (0,0)
9514 1404 393
Answer:
y = -1/16x^2 +4
Step-by-step explanation:
The vertex is halfway between the focus and directrix, so is at (0, 4). The focus is 4 units below the vertex, so "p" = -4. For vertex (h, k) and focus-vertex distance p, the equation is ...
y = 1/(4p)(x -h)^2 +k
Using the values we determined, this is ...
y = -1/16x^2 +4

Decompose and use the distributive property to find the product of 9 × 8.53.
76.77
72.72
76.5
79.2
Answer:
First option. 76.77
Step-by-step explanation:
The distributive property of the multiplication with respect to the sum can be written as:
[tex]x ( y + z ) = xy + xz[/tex]
We can take advantage of this property to find the product of 9*8.53 if we write:
8.53 = 8 + 0.53, thus:
[tex]9*8.53=9*(8+0.53)[/tex]
Applying the distributive property:
[tex]9*8.53=9*8+9*0.53[/tex]
Operating:
[tex]9*8.53=72+4.77=76.77[/tex]
Thus:
9*8.53=76.77
First option. 76.77

Tickets to a movie cost $11 for adults and $7 for students. A group of friends purchased 8 tickets
for $76. Write a system of equations to represent the situation. How many adult tickets and
student tickets were purchased
Answer:
5 Adult tickets were purchased and 3 student tickets were purchased.
Step-by-step explanation:
Write the problem as an equation like this
11x+7x=76
Now make an equation for the number of purchased tickets. Let x be adult and y be students.
x+y=8
Rewrite x + y = 8 as y = -x +8
Substitute y = -x + 8 into the first equation for y.
11x+7(-x+8)=76
11x+(-7x)+56=76
solve for 11x+(-7x)
4x+56+76
subtract 56 from both sides
4x=20
Divide both sides by 4
X=5
x + y = 8
5 + y = 8
y = 3
5 Adult tickets were purchased and 3 student tickets were purchased.
