Answer: 1.6 per 1 minute

Answer step by step:

2.4miles=1.5 minutes

2.4/3=

0.8 x 2 =

1.6

Because 1.5 can be split into 3 parts to get one-third that times 2 makes the minutes into 1 minute
So it can go 1.6 km in 1 minute

Answer: About 14.14 in^3

Step-by-step explanation:

We know that the circumference of a sphere is C=2πr. We are given that the circumference is 9.42 in. We can find the radius to get our volume.

$9.42=2\pi r$

$4.71=\pi r$

$r=1.5\\$

Now that we know radius, we can find our volume.

$V=\frac{4}{3} \pi r^3$

$V=\frac{4}{3} \pi (1.5)^3$

$V=14.14in^3$

According to the line plot, what is the total weight gained by the dogs that gained 1/8 f a pound or 3/4 of a pound?

3 1/8

First you take the all the dogs that gained 3/4 (which is 4)
Then you multiply it by 4

3/4x4=3
Then you add the dogs that gained 1/8 of a pound

3+1/8=3 1/8

-3x^2 plus 24x = 27 complete the square

Rudik [331]

You can divide the whole expression by -3:

$-3x^2+24x=27 \iff x^2-8x = -9$

Recalling that

$(x-a)^2=x^2-2ax+a^2$

Let's compare the middle term:

$-8x = -2ax \iff a=4$

So, we want to complete

$(x-4)^2 = x^2-8x+16$

Which differs from $x^2-8x$ by 16. So, if we add 16 to both sides, we have

$x^2-8x=-9 \iff x^2-8x+16=7 \iff (x-4)^2=7$
