can anyone help me with the question?

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:

If the inequality states something untrue there is no solution. If an inequality would be true for all possible values, the answer is all real numbers.

Step-by-step explanation:

Answer;

If the inequality states something untrue there is no solution. If an inequality would be true for all possible values, the answer is all real numbers, To solve an equation means to find all numbers

that make the equation true. The numbers are

called solutions or roots of the equation. A

number that is a solution of an equation is said to

satisfy the equation, and the solutions of an

equation make up its solution set. Equations

with the same solution set are equivalent

equations.

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.

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]2^{2}[/tex] x [tex]3^{2}[/tex] x [tex]7^{1}[/tex])N

2. Organism A's population grows by [tex]2^{5}[/tex].

Answer:

factor 2^5

Step-by-step explanation:

=============================================

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.

Step-by-step explanation:

As seen from the graph, the curve crosses the x-axis when x = -1 and x = 1. The y-intercept of the curve is -1.

Hence, the quadratic equation of the curve is y = x^2 - 1.

Answer:

(2, 3)

Step-by-step explanation:

Since the problem says to add 5 to x, and subtract from y, you can do x = -3 + 5 and y = 4 - 1 to get (2, 3)

Answer:

[tex]x<-\frac{7}{10}[/tex]

Step-by-step explanation:

[tex]10x - 5 <41 - 53[/tex]

[tex]10x-5<-12[/tex]

Add 5 to both sides:

[tex]10x-5+5<-12+5[/tex]

[tex]10x<-7[/tex]

Divide both sides by 10:

[tex]\frac{10x}{10}<\frac{-7}{10}[/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

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]

Answer:

B

Step-by-step explanation:

The picture represents a compass and a straightedge construction of bisecting a line segment.

- Bisect a line segment

Option C is the correct answer.

A segment bisector is a line, a ray, a line segment, or a point that cuts a line segment at the center dividing the line into two equal parts.

We have a figure,

There are two line segments.

One line segment is bisected by the compass at point B.

One line segment is bisected by the compass at point F.

Thus the picture represents a compass and a straightedge construction of bisecting a line segment.

- Bisect a line segment

Option C is the correct answer.

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

Pls make me brainliest much appreciated

The transformation that maps the pre-image to the image i.e. ABCD to A'B'C'D'  is the Dilation transformation.

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.
