Complete the table:

kilometers
8,000
9,000
5
7

Answers

Answer:

Remember while answering, 1 kilometer = 1,000 meters

5,000 ⇒ 5

6,000 ⇒ 6

7,000 ⇒ 7

8,000 ⇒ 8

9,000 ⇒ 9

Step-by-step explanation:

1 kilometer is 1,000 meters because "kilo" means 1,000

Knowing this we can make an equation to figure this out

When we know x, or meters, we can do y = x/1,000

When we know y, or kilometers, we can do x = 1,000y

can someone help :(!

Answers

Answer:

A

Step-by-step explanation:

You should know the area of a circle, A = πr².

So, all you need to find is the area of half a circle, or A = [tex]\frac{1}{2}[/tex] πr²

We see that the radius is half of the diameter or r = 6 in.

A = [tex]\frac{1}{2}[/tex] (3.14)(6)²

A = 56.52 in²

The awnser for this should be a

Item 3
Solve for a.

a+(−4)=−13




a=−17

a=−9

a = 9

a = 17

Answers

Answer:

a = -9

Step-by-step explanation:

a+(-4)=-13

add 4 to each side

a-4+4 = -13+4

a = -9

Answer:

a = - 9

Step-by-step explanation:

a  + (-4) = -13

Add  4 to both sides

a + (-4) + 4 = -13 + 4

       a + 0 = -9

        a = -9

What is Trigonometry?

The branch of mathematics concerned with specific functions of angles and their application to calculations. In trigonometry, there are six functions of an angle that are often utilised. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their names and acronyms (csc).

Given:

B = 8

Using Trigonometry

tan 29 = P/ B

0.554 = P / 8

P = 8 x  0.554

P = 4.432

Hence, the measure for BC is 4.432

60d+65n=2800
50d+45n=2150

Answers

From the second equation we can find that d=43-(9/10)*n
we can put this equation into the first one,
So we have equation 60(43-(9/10)*n)+65n=2800
Solving that we get n=20
60d+65*20=2800
d=25

So the answer is d=25 and n=20
