a tank holds 480 gallons of fuel. if it drained at a rate of 120 gallons Per minute, it will be empty in __ seconds

Step-by-step explanation:

Ok so if you didn't know, : is another way to write / so 24:28 is the same thing as 24 divided by 28. Or if you just wanted to simplify to most, you just want to find the largest common factor and divide it by both.

24:28 = 6:7

250:400 = 5:8

270:30 = 9:1

4:80 = 1:20

55:33 = 5:3

1000:100 = 100:10

560:80 = 7:1

20:340 = 1:17

Answer: 24:28= 6:7

250:400= 5:8

4:80= 1:20

55:33= 5/3

1000:100= 10:1

560:80= 7:1

20:340= 1:17

Step-by-step explanation:

Divide the numbers on each side of the ratio by Common Factors until what's left can't be divided any further.

One example, last one:

20:340 both divisible by 10, so you get 2:34. Both even numbers so divide by 2. You get 1:17. They can't be divided any further to get whole numbers, so that's the answer.

Answer:

C 60

Step-by-step explanation:

This is because if you do 303+60=363 and then you do 363/11 you get 33. So x=60

60

Multiply both sides of the equation by 11:

303 + x =363

Move constant to the right side and change its sign:

x = 363 - 303

Then,subtract the numbers:

x = 60

Quantity of water with Henri = 16 litres

Quantify of water he will need for one cup of coffee = 200 ml

Number of cups of coffee he can make with a full cup of water :-

[tex] = 16 \: litres \: = 16000 \: ml[/tex]

[tex] = \frac{16000}{200} [/tex]

[tex] = 80 \: cups \: of \: coffee[/tex]

So , Henri can make 80 cups of coffee with one full bottle of water .

Quantity of water needed to make 80 cups of coffee = 16,000 ml

Quantity of water needed to make one cup of coffee :-

[tex] = \frac{16000}{80} [/tex]

[tex] = 200 \: ml[/tex]

So , 200 ml of water is needed to make one cup coffee .

Quantity of water he needs to make 250 cups of coffee :-

[tex] = 200 \times 250[/tex]

[tex] = 50000 \: ml[/tex]

So , Henri needs 50,000 ml of water to make 250 cups of coffee .

Number of water containers he will use :-

[tex] = \frac{50000}{16000} [/tex]

[tex] = 3.125 \\ = 3 \: water \: containers[/tex]

So , Henri will use 3 full water containers to make 250 cups of coffee .

Money charged per one coffee = 8 cents

Money charged for 250 coffees :-

[tex] = 250 \times 8[/tex]

[tex] = 2000 \: cents[/tex]

So , Henri will make 2000 cents if he sells 250 cups of coffee .

Therefore , Henri will use 3 full containers of water to make 250 cups of coffee and he he will make 2000 cents by selling 250 cups of coffee .

Answer:

m = -2

Step-by-step explanation:

To find the slope of a line, use the equation:

m = y2 - y1 / x2 - x1

Then, substitute in values:

20 girls watch Long Ranger , 110 first graders watch Sesame Street , 20 boys watch Simpsons, and 70 girls watch Simpsons.

" Random sampling is a process of observing samples using such technique that each sample has equal probability."

According to the question,

As per the information of random samples given in the table,

Total number of boys are  = 100

Total number of girls = 200

For boys

Long Ranger + Sesame Street + Simpsons = 100

⇒  50 + 30 + Simpsons = 100

⇒ Number of boys view Simpsons = 100 - 80

                                                          = 20

In Long  ranger column,

50 Boys + ___girls = 100

⇒ Number of girls watching Long Ranger = 100 -50

                                                                   = 50

In Sesame street

30 boys + 80 girls = 110 Total viewers

Number of girls watching Simpsons = 90 -20

                                                            = 70

Hence, 20 girls watch Long Ranger , 110 total boys and girls watch Sesame Street , 20 boys watch Simpsons, and 70 girls watch Simpsons.

The first account, she invested = $4200 and in the second = $4800

Step-by-step explanation:

Let us assume that Genevieve invests $x at 6% ,

Hence, she invests ($9000 - $x ) at 4% ,

It's given that the combined interest from both of the above accounts is $444,

So,

0.06x + 0.04 (9000 - x) = 444

=> 0.06x + 360 - 0.04x = 444

=> (0.06x - 0.04x) + 360 = 444

=> 0.02x = 444 - 360

=> 0.02x = 84

=> x = 84/0.02

=> x = 8400/2 (By multiplying the denominator and numerator)

=> x = 4200

Therefore, 9000 - x = 9000 - 4200 = 4800

$4200 at 6% and $4800 at 4%

Therefore, the first account, she invested = $4200 and in the second = $4800

the male smoke more

Answer:

B.

Step-by-step explanation:

First you need to figure out how many numbers there are, so with this you can simply count 10. Then use the formula to plug in the numbers: 10(22-77)/2 to get the answer.

The required sum of the arithmetic progression is -275.

The arithmetic sequence is given 22, 11, 0, -11, ..., –77, sum of the sequence is to be determined.

Arithmetic progression is the series of numbers that have common differences between adjacent values

Here,
first term (a) = 22
Last term (l) = -77

Now,
l = a + (n - 1)d
-77 = 22 + (n - 1) *(-11)
-77 - 22 = (n - 1)(-11)
n - 1 = 9
n = 10

Now,
sum of the arithmetic sequence,
s = n / 2 [a + l]
s = 10 / 2 [22 - 77]
s = 5 [-55]
s = -275

Thus, the required sum of the arithmetic progression is -275.
