Take the total number of gallons and multiply by the fraction it is holding

75 *3/5

75/5 *3

15*3

45

Answer: 45 gallons

Step-by-step explanation: Using proportions, I did ?/75 = 3/5. I cross multiplied so 75 x 3 = 225 divided by 5 = 45.

Answer : The different is, find BC - AC and find AC + CB, find AB and find CA + BC are same.

Step-by-step explanation :

As see that, AB is a line segment in which point C is represented in between the line.

As we are given that:

AC = 3

CB = 7

So,

AC + CB = 3 + 7 = 10

Similarly,

CA + BC = 3 + 7 = 10

Similarly,

AB = AC + CB = 3 + 7 = 10

But,

BC - AC = 7 - 3 = 4

From this we conclude that, find AC + CB, find AB and find CA + BC are same things while find BC - AC is a different thing.

Hence, the different is, find BC - AC and find AC + CB, find AB and find CA + BC are same.

Answer:

Find BC-AC is the correct answer

Answer:

[tex]n=\frac{3f-8}{10}[/tex]

Step-by-step explanation:

So we have the equation:

[tex]\frac{3}{4}f-\frac{5}{2}n=2[/tex]

First, remove all the fractions by multiplying by the LCM of the denominator.

The LCM of 4 and 2 is 4. Thus:

[tex]4(\frac{3}{4}f-\frac{5}{2}n)=4(2)[/tex]

Distribute:

[tex]4(\frac{3}{4}f})-4(\frac{5}{2}n})=4(2)[/tex]

Simplify:

[tex]3f-10n=8[/tex]

Subtract 3f from both sides:

[tex](3f-10n)-3f=(8)-3f\\-10n=8-3f[/tex]

Divide both sides by -10:

[tex]n=\frac{8-3f}{-10}[/tex]

Divide by -1:

[tex]n=\frac{3f-8}{10}[/tex]

And this is our answer :)

n = (3f - 8)/10

3f/4 - ²⁾5n/2 = ⁴⁾2

3f - 10n = 8

3f - 8 = 10n

n = (3f - 8)/10

Answer:

a = 13

b = 52

a + b = 65

Step-by-step explanation:

a*b = 676

b/a = 4

b = 4a

a*4a = 676

4a² = 676

a² = 676/4

a² = 169

a = 13

b = 4a

b = 4(13)

b = 52

a + b

13 + 52

65

Answer:

7.2 × 28.8 = 9. 6 × 21.6

Step-by-step explanation:

Given the equation:

7.2∕9.6 = 21.6∕28.8

The equation which provides the multiplication of the means and the extremes in the equation provided above can be obtained through cross multiplication of the two ratios or proportion.

(7.2 / 9.6) = (21.6 / 28.8)

L. H. S = R. H. S

(numerator of L. H. S * denominator of R. H. S) = (denominator of L. H. S * numerator of R. H. S)

Hence, we have ;

7.2 × 28.8 = 9. 6 × 21.6

==================================================

Explanation:

If you have the two 3D solids with cross sections of equal area, and they are of the same height, then it can be proven the two volumes are the same. So it is possible for a cylinder and triangular prism to have the same volume.

An example would be that imagine you had a stack of pennies to form a large cylinder. The volume is found by computing the area of one penny's face (aka area of a circle) multiplied by the height of the stack.

Now imagine moving the stack to form a strange curve of any sort you want. The pillar has a bend in it now. It's no longer a perfect cylinder, but we still have the same volume since we haven't destroyed any of the pennies.

All we've done is move things around. The small pieces all have the same volume, so the total volume is still the same as well. So this is one application of Cavalieri's principle.

Answer:

the answer is c or the third line

Step-by-step explanation:

lets see all choices by solving them

so the answer is 13 means not negative

2. The second line 5-8-(-6)

Also now we should follow the bodmas rule

- 3 + 6

3 the answer is 3 so it means not negative

3. The third line 6+6-17

Now it is simple we solve it

12 - 17

-5 the answer is -5 means negative

4. The fourth line 6-4-(-8)

Again we need bodmas rule

-2 + 8

6 the answer is 6 means not negative

Answer:

A'(0,4)

Step-by-step explanation:

You would just add 1 to the x and subtract 3 form the y and you would get A prime or A'(0,4) so that would be your answer

Answer:

See below.

Step-by-step explanation:

So we know that a gym membership costs $25 plus $14 each month.

In other words, the one-time cost is $25 and there will be a cost of $14 each month.

We can write this as:

[tex]f(x)=14x+25[/tex]

Where f(x) equals the total cost given the number of months x.

For 6 months, the total cost will be:

[tex]f(6)=14(6)+25\\f(6)=84+25\\f(6)=\$ 109[/tex]

Step-by-step explanation:

It is given that,

A rescue company determined that 90 out of 100 calls rescue company determined that 90 out of 100 calls. We need to find the fraction of their calls that were true emergencies.

Fractions can be written as true value on the denominator and the part of it on the numerator.

The required value is : [tex]\dfrac{90}{100}=\dfrac{9}{10}[/tex]

So, (9/10) describes the fraction of their calls that were true emergencies.

Answer:

  62.8 m

Step-by-step explanation:

The length of one lap is ...

  C = 2πr = 2π(25 m) = 50π m ≈ 157.08 m

Sarah is gaining ground on John at the rate of 2.7 m/s -2.2 m/s = 0.5 m/s. So it will take Sarah ...

  157.08 m/(0.5 m/s) = 314.16 s

to run 1 lap farther than John does.

It takes Sarah ...

  157.08 m/(2.7 m/s) = 58.18 s

to run 1 lap, so in the time it takes her to catch John, she will have run ...

  314.16 s/(58.18 s/lap) = 5.4 laps

She (and John) will be 0.4 laps from their start when they meet again. That distance is ...

  (0.4)(157.08 m) = 62.8 m

Sarah will catch and pass John 62.8 meters from their starting position.

Answer:

10/62, 5/31,  or 16.129%

Step-by-step explanation:

First you have to add all of the balloon colors together to get the entire sample size.

47 + 5 + 10 = 62

Next, you need to know the how many of the balloon colors you what the probabilty for that are in the sample size.

10 black balloons.

Finally, you divide the number of black balloons by total balloons to find the probability of randomly choosing one.

10/62 = 5/31 or 16.129%

Answer:

width = 2 ft

length = 8 ft

Step-by-step explanation:

area = L x W

area = 16 ft^2

width = x

length = 2x+4

width = 2 ft

length = 2(2)+4

length = 4+4

length = 8 ft

area = 8 x 2 = 16 ft^2

Question:

Which of the following is NOT a formula for determining complementary probability?

A. P(outcome) = 1- P(-outcome)

B. P(outcome) - P(-outcome) = 1

C. P(outcome) + P(-outcome) =1

D. P(-outcome) = 1 - P(outcome)​

Answer:

[tex]P(outcome) - P(-outcome) = 1[/tex]

Step-by-step explanation:

Required

Determine which option is not a formula of complementary probabilities

From the list of given options, the complementary probabilities are P(outcome) and P(-outcome)

In probability;

[tex]P(outcome) + P(-outcome) = 1[/tex] --- Equation 1

Subtract P(outcome) from both sides

[tex]P(outcome) - P(outcome) + P(outcome) = 1 - P(outcome)[/tex]

[tex]P(-outcome) = 1 - P(outcome)[/tex]  ------ Equation 2

Subtract P(-outcome) from both sides of equation 1

[tex]P(outcome) + P(-outcome) - P(-outcome) = 1 - P(-outcome)[/tex]

[tex]P(outcome) = 1 - P(-outcome)[/tex]

Equation 1, 2 and 3 represents options A, C and D

While option B is out of place

Hence, option B is not a formula of complementary probability

I am 1 brainly away from the next rank, your help would be appreciated

Answer:

  15 mph

Step-by-step explanation:

The cyclists will cover distance at a rate proportional to their speed. So, the distance ratio is ...

  faster cyclist distance : slower cyclist distance = 3 : 1

Then the faster cyclist covers 3 : (3+1) = 3/4 of the total distance, or (3/4)(40 mi) = 30 mi.

That distance took 2 hours for the faster cyclist, so the speed was ...

  speed = distance/time = 30 mi/(2 h) = 15 mi/h
