Answer:

2 hrs

Step-by-step explanation:

The formula for speed is given as:

v=\frac{d}{t}\\\\t=vd

Let X be the speed of plane B. Given that the time to cover there respective distance is equal, we can equate as below:

Time=\frac{Distance }{Speed}\\\\\frac{750}{x}=\frac{900}{x+75}\\\\750(x+75)=900x\\\\\\x=375\ mph

Plane A's time is therefore calculated as:

Time=\frac{Distance}{Speed}\\\\=\frac{750}{375}\\\\=2\ hrs

Hence, it takes A 2 hrs to travel 750 miles.

Answer:

18lbs of Mexican Shade Grown coffee

Step-by-step explanation:

Since this is a ratio problem and we are given three values and one variable x (pounds of Mexican Shade Grown coffee needed) we can use the Rule of Three to solve this problem. In this rule we simply multiply the diagonal available values and divide by the third value to get the value of the variable, like so...

90lbs Gazebo  <=====>   27lbs Mexican Blend

60lbs Gazebo  <=====>   x lbs Mexican Blend

(60 * 27) / 90 = x

1620 / 90 = x

18 lbs = x

We need 18lbs of Mexican Shade Grown coffee blend to mix with the 60lbs of Gazebo blend

Explain how you would solve 5x - 3 = 9. (there should be a minimum of 2<br> complete sentences). *
SpyIntel [72]
Haha, you first start off with adding 3 to both sides, cancelling the -3, and adding it to 9. you end up with 5x=12, in which you divide both sides by 5. you get 2 and 2/5 or 12/5! hope that helps :)

What is the simplest form of the expression? 3sqrt(24a^10b^6)?
Anastasy [175]

Answer:

\text{The simplest form is }6\sqrt6a^5b^3

Step-by-step explanation:

Given the expression 3sqrt(24a^{10}b^6).

we have to find the simplest form of the expression.

3sqrt(24a^{10}b^6)

=3(24^{\frac{1}{2}}a^{\frac{10}{2}}b^{\frac{6}{2}})

=3(24^{\frac{1}{2}}a^5b^3)

=6\sqrt6a^5b^3

which is the simplest form of the given expression.
