For the first one ,

Let no. Of child be x
And adults are y

So, 210x+315y=2205
And other eqn will be, X+y= 9

By solving, x=6 , and thus y will be 3

So, no of children are 6 and no of adults are 3 !!

The given expression 8(4)^2+2^4 is equal to 144 or 12^2

<em><u>Solution:</u></em>

Given expression is:

8(4)^2+2^4

We have to evaluate the above given expression

We know that,

(4)^2 = 4 \times 4 = 16

2^4 = 2 \times 2 \times 2 \times 2=16

Substituting these in above given expression, we get

8(4)^2+2^4=8 \times 16+16\\\\8(4)^2+2^4= 128+16\\\\8(4)^2+2^4=144

Also we know that,

12 \times 12 = 144

Therefore,

8(4)^2+2^4=144 = 12 \times 12 = 12^2

Thus the given expression 8(4)^2+2^4 is equal to 144 or 12^2

If n-2 = 1/16, then n could be which of the following?
arlik [135]
The answer is E.4

The equation is: n ^{-2}=  \frac{1}{16}

Since x^{-a}= \frac{1}{ x^{a} }, then n^{-2} = \frac{1}{n^{2} }

Therefore, the equation is:
\frac{1}{ n^{2} } =  \frac{1}{16}
⇒ n^{2} = 16
    n= \sqrt{16}=4

The circumference of a circle is 15pie centimeters. What is the area of the circle in terms
Sedaia [141]

Answer:

176.71 cm

or

56.25π cm

Step-by-step explanation:

The formula for the circumference of a circle is:

C = πd

Where C is the circumference and d is the diameter

Let's substitute the circumference given into this formula:

C = πd

15π = πd

Now, we can solve this equation for d.

Divide by π on both sides:

15π = πd

/π      /π

15 = d

Therefore, the diameter is 15 cm.

We need to find the area. The formula for the area of a circle is:

A = πr²

First, let's find the radius. The radius is half of the diameter, so divide the diameter by 2.

15/2 = 7.5

radius = 7.5 cm

Now, we can solve for the area.

Substitute into the formula for area:

A = πr²

A = π(7.5²)

A = π(56.25)

A ≈ 176.71

Therefore, the area is approximately 176.71 cm, or in terms of pi, 56.25π.
