Select all the ratios that are equivalent to the ratio 12:3. explain how you know( show multiplication or division)

grigory [225]

Answer:

C 4:1

D 24:6

F 1200:300

Step-by-step explanation:

The given ratio is $\frac{12}{3}$

Simplify

Divide by 3 both numerator and denominator

$\frac{4}{1}$

<u><em>Verify each case</em></u>

case A) we have

$\frac{6}{1}$

Compare with the given ratio

$\frac{6}{1} \neq \frac{4}{1}$

therefore

The ratio is not equivalent

case B) we have

$\frac{1}{4}$

Compare with the given ratio

$\frac{1}{4} \neq \frac{4}{1}$

therefore

The ratio is not equivalent

case C) we have

$\frac{4}{1}$

Compare with the given ratio

$\frac{4}{1}=\frac{4}{1}$

therefore

The ratio is equivalent

case D) we have

$\frac{24}{6}$

Simplify

Divide by 6 both numerator and denominator

$\frac{4}{1}$

Compare with the given ratio

$\frac{4}{1}=\frac{4}{1}$

therefore

The ratio is equivalent

case E) we have

$\frac{15}{6}$

Simplify

Divide by 3 both numerator and denominator

$\frac{5}{2}$

Compare with the given ratio

$\frac{5}{2} \neq \frac{4}{1}$

therefore

The ratio is not equivalent

case F) we have

$\frac{1,200}{300}$

Simplify

Divide by 300 both numerator and denominator

$\frac{4}{1}$

Compare with the given ratio

$\frac{4}{1}=\frac{4}{1}$

therefore

The ratio is equivalent

case G) we have

$\frac{112}{13}$ ----> irreducible

Compare with the given ratio

$\frac{112}{13} \neq \frac{4}{1}$

therefore

The ratio is not equivalent

10m3 of air weigh 13 kg. Chapter Reference c How much does the air weigh in a room 4.2m long, 3.5m wide, and 2.6m high?

Zarrin [17]

Answer:

The air weight in a room is 49.69 kg.

Step-by-step explanation:

It is given that the room is 4.2m long, 3.5m wide, and 2.6m high. It is also given that 10 m³ of air weigh 13 kg.

The formula to find the volume of cuboid is,

$V=l\times b\times h$

$V=4.2\times 3.5\times 2.6$

$V=38.22$

The volume of room is 38.22 m³.

Since it is given that, 10 m³ of air weigh 13 kg. So,

$1 m^3=\frac{13}{10}kg$

$1 m^3=1.3kg$

So the air weight in the room is,

$\text{Air weight}=1.3\times 38.22$

$\text{Air weight}=49.686\approx 49.69$

Therefore the air weight in a room is 49.69 kg.

Rewrite the decimal fraction as a decimal number.

fiasKO [112]

Answer

8.025

Step-by-step explanation:

If you count the zeros in 1000, it's three. Count three starting from the back of 25. Add 0 in front of 25 to make it a three digit number. You then put the decimal point with the whole number.
