The answer to the given question is letter "B".

We will compute first individually
The distance at 1 min. =60
At 2 minutes= 60 +0.4*60 = 84
At 3 minutes = 84 +0.4*84 = 117.6
At 4 minutes = 117.6 + 0.4*117.6 = 164.64
At 5 minutes = 164.64 + 164.64*0.4 = 230.5
At 6 minutes = 230.5 + 230.5*0.4  = 323

Since the answer is letter "B" when we calculate using this equation in B, we will arrive at the same answer at 6 minutes:

D = 323

Illinois' population is now 12.5 million and decreasing by 0.1 million each year. On the other hand, Arizona's population is 6.9
Gekata [30.6K]

Answer:

8 years

Step by step guide:

100,000 x 8 = 800,000

600,000 x 8 = 4,800,000

6,900,000 + 4,800,000 = 11,700,000

12,500,000 - 800,000 = 11,700,000

Use the Pythagorean theorem to find the length of the leg in the triangle below. side a is 35 , and side c is 21. What is B?
garri49 [273]

Answer:

b=-784!

Step-by-step explanation:

If pythagorean theorem is the following (see below), then we can work backwards in order to solve for b!

a^{2} +b^2=c^2

35^2 +b=21^2\\1225+b=441

Now all that's left is to subtract 1225 and we should have our answer!

b=-784!

8 (3x - 1) = 2 (9 – 7x)
Leto [7]

Answer:

8 (3x - 1) = 2 (9 – 7x)

24x - 8 = 18 - 14x

24x + 14x - 8 = 18 -14x + 14x

38x - 8 = 18

38x - 8 + 8 = 18 + 8

38x = 26

38x / 38 = 26 / 38

x = 13/19  

Step-by-step explanation:

1. distribute both sides

2. add 14x to both sides

3. add 8 to both sides

4. divide both sides by 38 to get x

The length of a rectangle is 8 in. more than its width. The perimeter is 52 in. What is the length of the rectangle?
Levart [38]
L=w+8 \\\\ P=2L+2w \\ P=52in \\\\ 2(w+8)+2w=52 \\\\ 2w+16+2w=52 \\\\ 4w=52-16 \\\\ 4w=36 \\\\ \boxed{w=\frac{36}{4}=4in} \\\\ L=4+8 \\\\ \boxed{L=12in}
