Answer:
52°
Step-by-step explanation:
Let the measure of the third angle be x°.
Since, straight line is broken into three angles. So, the sum of all the three angles will be equal to 180°.
38° + 90° + x = 180°
128° + x = 180°
x = 180° - 128°
x = 52°
Answer:
52°
Step-by-step explanation:
So, we basically know that,
A straight Angle=180°
When it has been broken into 3 pieces, we have gotten one which is 38°and a right angle.
Now , we know that
A right angle= 90°
So, we need to do,
Sum of known angles= 38+90=128°
Lastly,
Unknown angle = 180° - 128° = 52°

omplete the square
x2+6x+3
Answer:
x1 = -3-[tex]\sqrt{6} \\[/tex] , x2 = -3+[tex]\sqrt{6}[/tex]
Step-by-step explanation:
x = [tex]\frac{-6+-\sqrt{6x^{2} -4 * 1 * 3} }{2 * 1}[/tex]
x = [tex]\frac{-6+- \sqrt{24} }{2}[/tex]
x = [tex]\frac{-6 +2\sqrt{6} }{2}[/tex]
x = [tex]\frac{-6 - 2\sqrt{6} }{2}[/tex]
x = -3 + [tex]\sqrt{6}[/tex]
x = -3 - [tex]\sqrt{6}[/tex]
There were a total of 480 tickets sold for the school play. Adult tickets sold for $8 and student tickets sold for $5. The ticket sales brought in $3369. How many adult tickets and student tickets were sold?
Step-by-step explanation:
Let A be the number of adult tickets and
let S be the number of student tickets.
From the question we know that
A + S = 480
The revenue from the adult tickets is
A x $8
and the revenue from the student tickets is
S x $5
So the total revenue is
A x $8 + S x $5 = $3369
We can change the first equation to
S = 480 - A
and then plug this into the second equation to get
A x $8 + (480 - A) x $5 = $3369
Simplify the equation to obtain
A = 323
Plug this value into the first equation to obtain
S = 157
Square ABCD is shown below.
If BD = 8x - 50, and DE = 2x + 5, find BE.
A) 15
B) 35
C) 25
D) 45
Answer:
35 is the length of BE
Step-by-step explanation:
2(2x + 5) = 8x - 50
4x + 10 = 8x -50
10+50 = 8x-4x
60= 4x
15 = x
2x + 5 = length of BE equal to length of DE
2(15) +5 = BE
30 +5
35 is the length of BE

Joe has 0.4 of a black forest cake, which is 14 slices of the cake,left. How many slices of cake were there originally?
Answer:
35 slices originally
Step-by-step explanation:
1. 0.4 means 40%
2. if 14 slives equal 40% we need to divide by 4 to find 10%
3. 14 divided by 4 is 3.5
4. then we multiply 3.5 (10% of the cake) by 10 because 10•10=100(%)
3.5•10 equals 35 slices

Two sisters want to save money to buy a game. The game costs $90. One sister has $36 and the other has $40. How much more money do they need?
what is M?
12(m + 15)=900
Answer:
M = 60
Step-by-step explanation:
First, use the distributive property:
12(m + 15) = 900
12 x m = 12m
12 x 15 = 180
We get the equation 12m + 180 = 900
Subtract 180 from both sides.
12m + 180 - 180 = 900 - 180
We get the equation 12m = 720
Divide by 12 on both sides.
12m/12 = 720/12
We get m = 60
I would appreciate brainliest but if not that's ok!
Answer:
60
Step-by-step explanation:
The equation is 12m +180=900 because we already did the distributive property. So now we have to minus 180 from both sides which gets us 12m=720. Now we divide both sides by 12. So 12m/12=m and 720/12=60. This leaves us with the answer, m=60.

A certain city has a population of about 100,000. There are 3,101 people with red hair in the city. Which of these is closest to the probability that a randomly selected person in the city has red hair?
Answer:
3%
hope this helps!
Step-by-step explanation:
The closest probability of a randomly selected person in the city having red hair is approximately 0.03 (or 3%).
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
A certain city has a population of around 100,000 people. In the city, there are 3,101 people with red hair.
The required probability can be calculated by dividing the number of people with red hair by the total population of the city:
= 3,101 / 100,000
= 0.03101,
It can be rounded to 0.03.
Thus, the required probability is 0.03.

Forty percent of the 70 buttons in the box had 5 holes
a. What fraction of the buttons did not have 5 holes?
b. How many buttons did not have 5 holes?
Answer: a. 0.6
b. 42 buttons
Step-by-step explanation:
a. What fraction of the buttons did not have 5 holes?
Since forty percent of the 70 buttons in the box had 5 holes, the number of buttons in the box that doesn't have 5 holes will be:
= 100% - 40%
= 60%
= 60/100
= 0.6
b. How many buttons did not have 5 holes?
This will be:
= 60% × 70
= 0.6 × 70
= 42 buttons

Hey there!
Guide for you do tackle them on your own in the nearer future.
• Percentages are out 100
• The word “of” means MULTIPLY in mathematics
1.)
10% of 40
10% = 10/100
= 10/100 • 40
10/100 = 1/10
1/10 • 40
40/10 = 4
4/1 = 4
Answer: 4 ☑️
2.)
25% of 8
25% = 25/100
= 25/100 • 8
25/100 = 1/4
1/4 • 8
8/4 = 2
2/1 = 2
Answer: 2 ☑️
3.)
20% of 5
20% = 20/100
= 20/100 • 5
20/100 = 1/5
1/5 • 5
5/5 =1
1/1 = 1

Answer:
AB = 2
Step-by-step explanation:
the triangles are similar so that means there is a constant ratio for each side length. so comparing the ratios from the bigger triangle to the smaller triangle, leaves us with 9/3 and 15/5. if you take those and divide them you get 3 for both of them which is the constant. so then in order to find the length of AB just take the side length of XY (6) and divide it by 3 (the constant ratio) and there you have your answer!

At which values of x does the graph of the function F(x) have a vertical asymptote? Check all that apply. F(x)= x-5 / x^2 + 3x -18
Answer:
x=3 , x=-6
Step-by-step explanation:
F(x)= (x-5) / (x² + 3x -18)
vertical asymptote: set denominator to 0 and solve x
x² + 3x -18 = (x+6) (x-3) = 0
x = 3 or x = -6
