12 gallons of water fill a tank to 3/4 capacity.If the tank is then filled to capacity, how many half-gallon bottles con be filled with the water in the tank?

Answers

Answer 1

Answer:

We need to find out how many gallons will fill the whole tank

we first write 3/4 into its decimal fraction. 3/4 = 0.75.

Now we form an equation

0.75 = 12

1 = x (where x is he number of gallons needed to fill whole tank)

Simplify the equation:

0.75 × x = 12 × 1

0.75x = 12

x = 12 / 0.75

x = 16

It will take 16 gallons to fill whole tank to capacity.

Half gallon bottles that can be filled from the tank are:16 x 2 = 32

So 32 half gallon bottles can be filled from the full tank.

Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work. 1/4x^3= -27/4

Answers

We can start by separating the x^3, and that means we have to multiply both sides by 4, resulting in x^3=27. Next, we can find the cube root of both sides ( as x is the cube root of x^3), getting x=3

The face of a clock has a circumference of 63 in. What is the area of the face of the clock?

Answers

Answer:

The area of the clock $= 315.41\ inch^(2)$

Step-by-step explanation:

We have been given the face of the clock that is $63\ in$

So that is also the circumference of the clock.

Since the clock is circular in shape.

So $2\pi(r)=63\ inch$

From here we will calculate the value of radius $(r)$ of the clock that is circular in shape.

Then $2\pi(r)=63\ inch =(63)/(2\pi) = 10.02\ in$

Now to find the area of the clock we will put this value of (r) in the equation of area of the circle.

Now $\pi (r)^(2)=\pi(10.02)^(2)=315.41\ in^(2)$

So the area of the face of the clock = $315.41\ in^(2)$

miss holman gave a 90 cent tip to a waitress for serving a meal costing $6.00. what is the percent of the bill was her tip?

Answers

Answer:

The tip was 15% of the meal.

Step-by-step explanation:

The amount of tip that miss Holman gave is 90 cent or $0.90

The total cost of the meal is $6.00

Let the tip is x% of the total cost of $6, so the amount of tip is,

$=6* (x)/(100)$

But as it given as $0.90, so

$\Rightarrow 6* (x)/(100)=0.90$

$\Rightarrow x=(0.90* 100)/(6)$

$\Rightarrow x=15\%$

Therefore, miss Holman gave a generous 15% tip to the waitress for serving the meal.

$90cent\ \ \ | convert\ cent \ into\ \$\n\n1dollar=100cent\n\n90cent= 0.9dollar\n\n(0.9)/(6)*100\%=(90)/(6)\%=15\%\n\nTip\ was\ 15\%\ of\ cost\ of\ meal.$

What is −4 5/11 − 2 4/11?

Answers

I think it might be -2 1/11 1. -4 5/11+2 4/11 2. 4+2=−2
Solving the fraction parts
−5/11+4/11=−1/11
Combining the whole and fraction parts
−2−1/11=−2 1/11
Solution by Formulas
First:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
−49/11+26/11
Applying the fractions formula for addition,
=(−49×11)+(26×11)11×11
=−539+286=121
=−253/121
Simplifying -253/121, the answer is
=−2 1/11

the answer would be 6 9/11
