What is the angle between any two windmills blades in the windmill

Andre and Morgan are both headed to Florida for vacation. Andre will drive 70 miles per hour. Morgan will drive 55 miles per hou

babymother [125]

Answer:

The number of hours Moran wold have driven before Andre catches up with him is 14 hours

Step-by-step explanation:

The given information are;

The speed with which Andre will drive = 70 miles per hour

The speed with which Morgan will drive = 55 miles per hour

The time of departure of Morgan = 3 hours before Andre departs

Let the time at which Andre catches up with Morgan be, t

We have, from the definition of distance traveled;

Distance traveled =Speed × Time

The distance Morgan would have driven in t hours = 55 × t

Given that to catch up with Morgan, Andre has to travel the same distance, and that Andre starts 3 hours late, we have;

The distance Andre would drive when Morgan has driven for t hours = 70 × (t - 3)

Therefore, since the distance at the point they meet is the same distance for them both, we have;

55 × t = 70 × (t - 3)

55 × t = 70 × t - 210

210 = 70 × t - 55 × t = 15 × t

t = 210/15 = 14 hours

Therefore, Morgan would have driven for 14 hours before Andre catches uo with him.

Rule for raising a power to a new power

KiRa [710]

The practical rule would be, times that number, by the result of the first time you multiplied the first number. But, it would all depend by how much your're raising the number by.

<u>For example:</u> $\boxed{4^6}$

We do, $(4*4*4*4*4*4)= \boxed{\bf{4^6}}= 4096$

But, once again, this was an example. This would show and illustrate the rule of "raising a power".<span />

Round each fraction to the nearest half and find the estimate.

erastova [34]

Answer: The result is one half ( $\frac{1}{2}$ )

Step-by-step explanation:

We have the following expression:

$\frac{2}{6}+\frac{1}{6}$

Since both fractions have the same denominator, we can just add both numerators and keep the denominator:

$\frac{2+1}{6}=\frac{3}{6}$

Dividing numerator and denominator by $3$ :

$\frac{\frac{3}{3}}{\frac{6}{3}}=\frac{1}{2}$ This is the result

-(-(-)(-)(-10x))=-5 solve for x

ElenaW [278]

-(-(-)(-)(-10x)) = -5

We need to cancel out the negatives, so we need to simplify this.

To make things a bit easier for you, we can begin by counting out how many negatives we have. After counting, you should have a negative number count of 5. However, one of the negatives is apart of (-10x) so we'll have 4 negatives and then an extra negative in with 10x.

Remember that "-" could also be looked at as "-1."

So, if we break this down into smaller parts and substitute "-" into "-1," then this'll look like this :

-1 × -1 × -1 × -1 × (-10x) = -5

Remember that a negative times a negative is always a positive.

So, since there are four negatives, then you just multiply it all together.

This results in 1 × (-10x) = -5

Simplify.

-10x = -5

Now, you simply divide both sides by -10.

-10x ÷ -10 = -5 ÷ -10

Simplify.

x = 1/2
