The answer is 357 miles. It is never asking how long or how many hours it took, it just says how many miles are left. What I did to get this answer is 400 - 43.

There are 99 miles left. 43(7)=301. 400-301=99.

The circumference of a circle can be found using the formula C = 2r. Which is an equivalent equation solved for r? r = C r = C(2

vaieri [72.5K]

Answer:

r equals StartFraction C Over 2 pi EndFraction

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

where

r is the radius of the circle

Solve for r

That means -----> isolate the variable r

Divide by 2π both sides

$\frac{C}{2\pi}=\frac{2\pi r}{2\pi}$

Simplify right side

$\frac{C}{2\pi}=r$

Rewrite

$r=\frac{C}{2\pi}$

r equals StartFraction C Over 2 pi EndFraction

Lenny is 3 times older than Max. When you subtract Max's age from lenny's age, you get 24. How old is Lenny and how old is max?

Helga [31]

Let Max be $x$ years.

Then Lenny is $3x$ years

When we subtract Max's age from Lenny's age we obtain $3x-x$

This is equal to $24$

Putting all together we have

$3x-x=24$

$2x=24$

$x=12$

$Therefore Max is 12 years and Lenny is 36 years$

Does secondhand smoke increase the risk of a low weight birth? A baby is “low birth weight” if it weighs less than 5.5 pounds at

11111nata11111 [884]

Answer:

H0: p = 0.078

Ha: p ≠ 0.078

Step-by-step explanation:

The researchers say that the rate is about 7.8%, or 0.078 as a decimal. That makes that the null hypothesis because using "is" in math is the same as saying "equals" and the null hypothesis always has the statement of equality in it. The reason there is a not equals to sign in the alternate is for this reason as well. The researchers say it is about that amount, not more or less than that amount. So it makes this a 2 tailed test. If the amount is significantly higher or lower, then we might have to reject the null hypothesis depending on the outcome of the test.
