Answer:

The answer is D.90°

Step-by-step explanation:

In this case, every measure has to be defined by three points and the vertex of this measure is in the middle point. The angle that is formed between two rays with the same endpoint is measured in degrees. The extreme points form the rays and the middle point is the vertex.

For example, if we want to know the measure ∠ABC, we have to located the points A, B and C, in the same order. Then the rays are in the same direction that A and C, and vertex will be in the point B (the middle one).

Also, there are some definitions for different range of angle measure. I have attached an image that show some definitions.

Finally, the measure ∠QRS corresponds to a right angle (It has the same notation that in the attached image).

Therefore, the measure ∠QRS is 90°

Find the area of the shaded region. Round to the nearest hundredth when necessary.

dusya [7]

Answer: 423.11 m^2

Step by step explanation:

Area of a circle formula pi*r^2

First solve the area of the big circle

3.14*21^2=1384.74 m^2

Now find the are of the smaller circle

r=21-3.5=17.5
3.14*(17.5)^2=961.63 m^2

Now we can minus the small area off the big area to get the shaded area.

1384.74-961.63=423.11 m^2

So the area of the shaded region is 423.11 m^2

What is 12.345 rounded to the nearest tenth

noname [10]

Rounding to the nearest tenth means rounding to the decimal place directly to the right of the decimal.

The rules of rounding are fairly simple. If the number to the right of the number you are rounding is greater than or equal to 5, you round up. If the number to the right is less than 5, you round down.

Let's take a look at the number 12.345.
First, round to the hundredths place. The number right before the 4 is 5, so we round up. This gives us the number 12.35.
Next, we have to round to the tenths place. The number to the right of the 3 is 5, so we round up as well. This gives us the number 12.4.

Answer: 12.4

Answer:

Q+D = 65, multiply both sides by 2525Q + 25D = 162525Q + 10D = 950 subtract to get 15D = 675 D = 675/15 = 135/3 = 45 dimes Q = 65-45 = 20 quarters25(20) + 10(45) = 500+450 = 950

How do i solve this kind of problem

Advocard [28]

Answer:

y=x-2

Step-by-step explanation:

to get -2 to -4 you would have to add -2

if we follow the pattern of subtracting 2 then you would see that -2 is b sense we are subtracting.

The m value doesn't have to change so we would leave the x how it is

The goal for this question is to find the pattern the numbers share though out the table.
