(85°
45
85
Ω

Answers

Answer:

The triangles are similar as the ratio of their corresponding sides are equal

Step-by-step explanation:

When two triangles are similar, the ratio of their corresponding sides are equal

As we can see, 85 is between 10 and 18

The ratio of the numbers will be ;

10/18 and 25/45

To the simplest terms;

5/9 and 5/9

Since the ratio is equal, then the triangles are similar

WILL GIVE BRAINLIEST, PLEASE EXPLAIN J=HOW TO FIGURE THIS PROBLEM OUT THANK YOU. The figure below shows a shaded region and a non-shaded region. Angles in the figure that appear to be right angles are right angles.

A picture of a rectangle is shown. The bottom of the rectangle is labeled 16 ft. The right side of the rectangle is labeled 8 ft. At the bottom left side of the rectangle there is a label that reads 2 ft. Inside the rectangle is a shaded region. The bottom of the region is labeled 8 ft and this side is perpendicular to the left side of the rectangle. The right side of the shaded region has a perpendicular line segment extending upward that is labeled 2 ft. At the top of this line segment is another line segment perpendicular to the right that reads 2 ft. At the end of this line segment is a perpendicular line segment extending upward that reads 1 ft. There is a line segment joining the end of this line segment with the top left corner of the rectangle.

What is the area, in square feet, of the shaded region?

Find the slope of the line from a graph. Will give brainliest!!!

Answers

Answer:

2/1 or 2

Step-by-step explanation:

to find the slope you have to calculate the rise over run, do this by picking two spots on the line that go thourgh the corner of a square. then count the amount up the is your rise then the lateral movement, the is your run.

this means the answer is 2/1 that can be simplified to 2.

Answer:

Maybe  -3

Step-by-step explanation:

I am not 100% sure but it is better than nothing,

since 3+3=6 I think after 3 is 6, and after 6 is 9. I think that because the more right the line goes you add  3 to every move. So therefore, 3-3=0, and 0-3= -3

Hope this helps. Also, I hope I gave you the correct answer.

What is a solution set to an inequality or an equation?

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality.

Set of such values is called solution set to the considered equation or inequality.

Assuming we want to solve for x the result can vary.

We are given to find the solution to the following compound inequality in interval notation.

Inequality Form:

−5 ≤ x ≤ 2

In a group of 60 students, 15 liked maths only, 20 liked science only and 5 did not liked any of two subjects. How many of them liked at least one subject?

Answers

Answer:

35

Step-by-step explanation:

Given

n (A) = 15

n (B) = 20

Students who do not like any subject = 5

Hence, number of students who would like either both or either of the two subjects = 60-5 = 55

n (A or B) = n (A) + n (B) - n (A and B)

Number of students linking both the subjects

55 - 15-20

= 55-35 = 20

Number of students linking only one subject = 60-20-5 = 35

Answer: what r u supposed to figure out

Step-by-step explanation:

Answer:

See below

Step-by-step explanation:

Given is the piecewise function.

It has three different pieces.

The first piecef(x) = 2, with x ≤ -2

Plot the point (-2,2) and draw a horizontal line to the left from this point

The second piecef(x) = 1/2x + 3, at the interval -2<x≤1

Plot two border points at x = -2 and x = 1:

f(-2) = 1/2*(-2) + 3 = 2, point (-2, 2)

and

f(1) = 1/2*1 + 3 = 3.5, point (1, 3.5)

Connect these two points with a line segment

The third piecef(x) = -7/8x + 35/8, at x > 1

Plot two points at x = 1 and x = 5 (5 is an example, it could be anything > 1)

f(1) = -7/8*1 + 35/8 = 28/8 = 3.5

and

f(5) = -7/8*5 + 35/8 = 0

Connect the two points (1, 3.5) and (5, 0) and extend the line to the right

Remember the point (-2,2) belongs to the first piece and the point (1, 3.5) belongs to the second piece.
