Answer:

2A / r^2 = pi

Step-by-step explanation:

A = 1/2 pi r^2

Multiply by 2

2A = pi r^2

Divide by r^2

2A / r^2 =  pi r^2/r^2

2A / r^2 = pi

Answer

9/20

Step by Step

I got this by turning the 1/4 into a 5/20 and then turned the 1/5 into a 4/20 and then added from there

5/20+4/20=9/20

You have to turn the fractions denominator into the same number by finding the lowest common denominator.

Answer:

f(n+1) = 13

Step-by-step explanation:

Answer:

They should all be true because she is 56 inches tall and the minimum for the roller coasters is 54 inches. So its probably the same minimum for the drop tower.

Step-by-step explanation:

Answer:

a.  True

b.  True

c.  True

d.  True

Step-by-step explanation:

all true because the min height to ride the drop tower is 51 in

and the roller coaster is almost the same as 51 in.

if Cindy is 56 in high, then Cindy can ride both the roller coaster and the drop tower.

Answer:

In the given figure the point on segment PQ is twice as from P as from Q is. What is the point? Ans is (2,1).

Step-by-step explanation:

There is really no need to use any quadratics or roots.

( Consider the same problem on the plain number line first.  )

How do you find the number between 2 and 5 which is twice as far from 2 as from 5?

You take their difference, which is 3. Now splitting this distance by ratio 2:1 means the first distance is two thirds, the second is one third, so we get

4=2+23(5−2)

It works completely the same with geometric points (using vector operations), just linear interpolation: Call the result R, then

R=P+23(Q−P)

so in your case we get

R=(0,−1)+23(3,3)=(2,1)

Why does this work for 2D-distances as well, even if there seem to be roots involved? Because vector length behaves linearly after all! (meaning |t⋅a⃗ |=t|a⃗ | for any positive scalar t)

Edit: We'll try to divide a distance s into parts a and b such that a is twice as long as b. So it's a=2b and we get

s=a+b=2b+b=3b

⇔b=13s⇒a=23s

Answer:

Increase the speed

Step-by-step explanation:

The only way to decrease the time it would take to travel over a distance would be to increase the speed.

Answer:

see below

Step-by-step explanation:

if time decreases.... the velocity will decrease.

ex.

d = v/t

100 m = v/10 sec  v = 1000 m/s

100 m = v/5 sec   v = 500 m/s

100 m = v/1 sec    v = 100 m/s

therefore,

if we decrease the time it takes for a car to travel over the same distance,

the velocity decreases too.

Answer:

y = 17

Step-by-step explanation:

3(y-13)=13

3y-39=12

3y=51

y=17

Answer:

y = 17

Step-by-step explanation:

3[y-13] = 12

3*y + 3*-13 = 12

3y - 39 = 12

3y = 12 + 39

3y = 51

y = 51/3

y = 17

Check:

3[17-13] = 12

Answer:

A

Step-by-step explanation:

Writing a number in scientific notation involves writing the number to the appropriate power of 10. Hence, the number written in scientific notation is [tex]6.312 \times 10^{7}[/tex]

Given the number : 63,120, 000

63,120,000 = 6312 × 10000

6312 = 6.312 × 1000

63,120,000 = 6.312 × (10000) × (1000) = 6.312 × 10000000

We can expressed the value to the power of 10 thus :

6.312 × 10000000 = 6.312 × [tex]10^{7} = 6.312 \times 10^{7} [/tex]

Therefore, the Number written in scientific notation is [tex]6.312 \times 10^{7}[/tex]

Answer:

210 divided 2 1/2= 84....

The 210 divided by 2 1/2 is 84.

To calculate 210 divided by 2 1/2, first, we need to convert the mixed number 2 1/2 to an improper fraction. The improper fraction for 2 1/2 is (2 * 2 + 1) / 2 = 5/2.

Now, we can perform the division:

210 ÷ 5/2

To divide by a fraction, we multiply by its reciprocal:

210 * 2/5

Now, perform the multiplication:

(210 * 2) / 5 = 420 / 5

Next, simplify the fraction by dividing the numerator and denominator by their greatest common divisor (GCD), which is 5:

420 ÷ 5 = 84

The result of 210 divided by 2 1/2 is 84. So, 210 ÷ 2 1/2 = 84.
