Answer:

The bottle hold 25 ounces of water

Step-by-step explanation:

To find the amount of water the bottle hold, we will follow the steps below;

let x be the number of ounces of water the bottle holds

3/5  of x  = 15 ounces

3/5  ×  x   = 15

\frac{3X}{5}   = 15

Multiply both-side of the equation by 5

\frac{3X}{5}  ×  5   =  15×5

At the left-hand side of the equation 5 will cancel-out 5 leaving us with 3x

3x = 75

Divide both-side of the equation by 3

\frac{3X}{3}  =  \frac{75}{3}

(On the left-hand side of the equation 3 at the numerator will cancel-out 3 at the denominator leaving us with x while on the right-hand side of the equation 75 will be divided by 3)

x = 25 ounce

A teacher gave a test to three classes that contained 27, 25, and 23 students. A total of 18 students scored an A on the test. B
salantis [7]
Ratio of classes A, B, C = 4 : 6 : 5, respectively
4 + 6 + 5 = 15
So, class A represents 4/15 of the TOTAL population
Class B represents 6/15 of the TOTAL population
Class C represents 5/15 of the TOTAL population

So, weighted average of 3 groups combined = (4/15)(65) + (6/15)(80) + (5/15)(77)
= 260/15 + 480/15 + 385/15
= 1125/15
= 75

Korvikt [17]

Answer:

A. x = 8.

B. x = 31.

C. x = 32.

Step-by-step explanation:

Here. the sum of the 2 parallel sides of the trapezoid = 2 * length of the middle line segment.

MN + RS = 2PQ

32+ x = 2*20

x =  40 - 32

x = 8.

MN + RS = 2PQ

20 + 42 = 2PQ

2x =  62

x = 31

MN + RS = 2PQ

22 + 42 = 2PQ

2x =  64

x = 32.

A car can travel 78 km using 6 litres of petrol. By using ratio and proportion methrfind how much petrol will be needed for trav
Anna71 [15]

Answer:

25 liters of petrol

Step-by-step explanation:

78 km = 6 liters

So the ratio is 78:6

Let's find the distance per liter:

78/6 = 13

So you travel 13 km per liter

To find the amount of liters for 325 km, you divide 325 by 13:

325/13 = 25

You would need 25 liters of petrol to travel 325 km.
