Find the values of x and y
Answer:
x = 30
y = 10
Step-by-step explanation:
3x° is a right angle so it equals 90°. To solve for x, you need to divide 90 by 3. This equals 30.
In order to find what the angle with y equals, you have to find the rest of them. So if you add 135° + 90° + 90° you get 215. Which is the missing angle.
So to solve for y in (5y - 5) = 45°, you add 5 to 45, which is 50 and then divide by 5. This is how you get y=10.

Answer:
C
-5n^2-8n+4
Step-by-step explanation:
The value of the expression after adding will be;
⇒ - 5n² - 8n + 4
What is Addition?
A process of combining two or more numbers is called addition.
Given that;
The expression is,
⇒ (3n² - 5n + 6) + (- 8n² - 3n - 2)
Now,
Solve the expression as;
⇒ (3n² - 5n + 6) + (- 8n² - 3n - 2)
⇒ 3n² - 5n + 6 - 8n² - 3n - 2
⇒ - 5n² - 8n + 4

U is the set of natural numbers less than 8. G is the set of even integers less than 10. Which is the
complement of set G in universe U? a.{1,3,5,7} b. G c. {2,4,6} d. {1,3,5,7,8}
=============================================
U = set of natural numbers less than 8
U = {1,2,3,4,5,6,7,8}
G = set of even integers less than 10
G = {..., -4, -2, 0, 2, 4, 6, 8}
Circle the items in G that are also in set U. Those items are {2,4,6,8}
Then go back to set U = {1,2,3,4,5,6,7,8} and erase 2,4,6,8 to be left with {1,3,5,7}
The complement of a set is everything that isn't in a given set. Think of it as the opposite.
How do I solve 18=6(2x-8)
Answer:
x= 5.5
Step-by-step explanation:
18=12x-48
-12x= -48-18
-12x= -66
x= -66/-12
x= 5.5
Answer:
Okay so first you distribute 6 into the parenthesis that gives you
18=12x-48
Then you add 48 on both sides
66=12x
then you divide
X=5.5

Organisms A and B start out with the same population size. Organism A’s population doubles every day. After five days, the population stops growing and a virus cuts it in half every day for three days. Organism bees population grows at the same rate but it’s not infected with the virus. After eight days how much larger is organism B’s population an organism A’s population?
1: By what factor does organism as population grow in the first five days? Express your answer as an exponential expression
Answer:
1. 252N = ([tex]2^{2}[/tex] x [tex]3^{2}[/tex] x [tex]7^{1}[/tex])N
2. Factor = [tex]2^{5}[/tex]
Step-by-step explanation:
Let the starting population size for organisms A and B be represented by N.
For organism A;
Day 0: N
Day 1: 2N
Day 2: [tex]2^{2}[/tex]N
Day 3: [tex]2^{3}[/tex]N
Day 4: [tex]2^{4}[/tex]N
Day 5: [tex]2^{5}[/tex]N
Day 6: [tex]2^{4}[/tex]N
Day 7: [tex]2^{3}[/tex]N
Day 8: [tex]2^{2}[/tex]N
For organism B;
Day 0: N
Day 1: 2N
Day 2: [tex]2^{2}[/tex]N
Day 3: [tex]2^{3}[/tex]N
Day 4: [tex]2^{4}[/tex]N
Day 5: [tex]2^{5}[/tex]N
Day 6: [tex]2^{6}[/tex]N
Day 7: [tex]2^{7}[/tex]N
Day 8: [tex]2^{8}[/tex]N
1. After the eight days, organism B's population is larger than organism A's population by;
[tex]2^{8}[/tex]N - [tex]2^{2}[/tex]N = 256N - 4N
= 252N

[tex]10x-5<-12[/tex]
Add 5 to both sides:
[tex]10x-5+5<-12+5[/tex]

[tex]x<-\frac{7}{10}[/tex]
Answer:
-0.7
Step-by-step explanation:
10x<41-53+5
10x<-7
x<-7/10 or -0.7

-1/3(y-3)=11
Answer:
y=-4
Step-by-step explanation:
Equation: -1/3(y-3)=11
First multiply -1/3 by y and by -3 because they are in parenthesis:
-1/3*y=-1/3y
-1/3*3=1
-1/3y-1=11
Next add 1 on both sides:
-1/3y-1+1=11+1
-1/3y=12
Now divide -1/3 on both sides:
-1/3y÷-1/3=12÷-1/3
y=-4

1. A light rail travels at a rate of 165 miles per
hour. If the light rail travels for 3 hours, then
how far did it go?
Answer:
495 miles
Step-by-step explanation:
If the light rail goes 165 miles per hour (mph) and if it was to travel for 3 hours you would multiply 165 mph x 3 = 495
Hey there!
[tex]Answer: \boxed{495\text{ miles}}[/tex]
[tex]Explanation:[/tex]
The light rail traveled 165 miles in one hour. The question is asking how many miles would it travel in 3 hours. So the only thing you have to do is multiply 165 miles by 3 hours.
[tex]165*3=495\\[/tex]
So it traveled 495 in 3 hours. So the answer to your question is:
[tex]\boxed{495\text{ miles}}[/tex]

Caleb painted a regular wall that was 15 feet long and 12 feet tall. He divided the wall into two congruent, right triangles and painted each try and go to different color. What was the area, and square feet, of each triangle?
Answer:
Step-by-step explanation:
Each triangle has a formula of 1/2 a*b
So one triangle = 1/2 * 12 * 15 = 90
So the other one is the same area of 90 square feet.
Together they make 180 square feet.
You can check this by simply multiplying a*b = 12 * 15 = 180 square feet.

The transformation that maps the pre-image to the image i.e. ABCD to A'B'C'D' is the Dilation transformation.
What is dilation?Changing in size without changing the shape of the given figure, such transformation is known as dilation.
We have,
According to the question:
Smaller Rectangle ABCD has side lengths 5, 4, 5, 4.
And,
Rectangle A'B'C'D' has side lengths 10, 8, 10, 8.
So,
The size of rectangle A'B'C'D' get increases as compared to rectangle ABCD.
Hence, We can say that the transformation dilation would transform the ABCD into the A'B'C'D' by dilation.
