abruzzese [7]3 years ago

Answer:

9 shirts

Step-by-step explanation:

20% of the shirts were blue

20% of 30 is 6

6 shirts were blue

1/2 of the shirts were black

1/2 = 50%

50% of 30 is 15

15 shirts are black

15 + 6 = 21

30 - 21 = 9

(or you could add the percentages to get 70%, and get 30%. 30% of 30 is 9.)

Hope this helps!

Sierra left $4.50 as a tip for a waiter. THis was 18% of the bull before the tip, How much was her total bill before the tip?
andreyandreev [35.5K]

let's say the bill without the tip is "x" amount, so that'd be the 100% of the bill, but we also know that 4.50 is the 18% of "x".

so if 4.50 is the 18% of "x", how much is "x"?


\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 4.50&18\\ x&100 \end{array}\implies \cfrac{4.5}{x}=\cfrac{18}{100}\implies 450=18x \\\\\\ \cfrac{450}{18}=x\implies 25=x

valkas [14]

Answer:

Given the bean bag made by beth is in the shape of cube with each side of the cube equal to 2 feet.

Now Also given that each bean bag holds 2 cubic feet of beans.

Let the number of bags of beans recquired are x

The total number of beans available are 2x cubic feet

Now the volume of the bean bag made by beth is

Volume = side^{3}

Volume =2^3

Volume = 8 cubic feet

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by gi
GuDViN [60]

The time that rocket will hit the ground, to the nearest 100th of second is 10.43 seconds

Given the equation representing the height reached by a rocket as:

y = -16x^2 + 157x + 104

The rocket will hit the ground when y = 0. Substituting y = 0 into the expression to get x;

0 = -16x^2 + 157x + 104\\16x^2 - 157x - 104 = 0\\

On factorizing:

x = 10.43 seconds

Hence the time that rocket will hit the ground, to the nearest 100th of second is 10.43 seconds
