The answer is:

C and D

Explanation;

Janie walked 10 miles first.

Then they walked 15 times the original 10 miles.

When you place that in a calculation, it looks like this:

10miles + (15 x 10miles)

Which is basically 10 + 15 x 10.
= 160

With D, you just use multiplication.

10 x 1 = 10
10 x 15 = 150

= 160

Kazeer [188]

Answer: The average was 9 years old find the average age of both groups is 10 years old.

Step-by-step explanation:

Formula foe average : $\text{Average} =\dfrac{\text{Sum of all observations}}{\text{Number of observations}}$

Given : The first group of students consists of 10 and their average age was 13 years old.

i.e. $13=\dfrac{\text{Sum of ages of students of first group}}{10}\\\\\Rightarrow\ \text{Sum of ages of students of first group}=13\times10=130$ (1)

The next group consisted of 30 students and their average was 9 years old.

i.e. $9=\dfrac{\text{Sum of ages of students of next group}}{30}\\\\\Rightarrow\ \text{Sum of ages of students of nextgroup}=9\times30=270$ (2)

Then from (1) and (2) , the sum of both groups (first group and next group )students = 130+270 =400

Combined students of both groups (first and next group )= 10+30=40

Now , the average of both groups = $\dfrac{\text{Sum of combined students}}{\text{combined students}}$

$=\dfrac{400}{40}=10$

Hence, the average was 9 years old find the average age of both groups is 10 years old.

If r=1 and 0=5pie/3, what is the approximate arc length?

Masja [62]

Answer:

5.236 units

Step-by-step explanation:

The relation between r, θ and arc length ( l ) is,

l = rθ

l = 1 * 5π / 3

( The value of π = 3.14 approximately )

5π = 5 x 3.14 = 15.7

l = 1 * 5π / 3

= 5π / 3

= 15.7/3

l = 5.236 units

Note : -

Arc length is denoted by " l ".

Nesterboy [21]

Answer:

2B/( h-q)=a

Step-by-step explanation:

2B=ha-qa

Factor out an a

2B=a(h-q)

Divide each side by ( h-q)

2B/( h-q)=a(h-q)/( h-q)

2B/( h-q)=a
