Answer:

2,920\ dam

Step-by-step explanation:

we know that

1 Kilometer (km) is equal to 100 dekameters (dam)

1\ km=100\ dam

To convert km to dam , multiply by 100

we have

29.2\ km

Convert to dam

29.2\ km=29.2(100)=2,920\ dam

The ratio of the dimensions of a rectangular patio are 4:7. if the shorter
Cerrena [4.2K]

If the ratio of the dimensions is 4:7 and the shorter dimension is 10ft, we know that the 10ft corresponds to the 4 in this scenario. We can set up the equation as follows:

\frac{4}{7} =\frac{10}{x}

You have to multiply by 2.5 to get from 4 to 10. And since we want to make sure we are maintaining the ratio, we have to multiply the denominator, 7, by 2.5 as well.

\frac{4}{7}*\frac{2.5}{2.5}=\frac{10}{17.5}

This means your shorter side has a length of 10ft and your longer side has a length of 17.5ft.

AREA

The formula for the area of a rectangle is: w*l

So we can plug our dimensions into the formula: 10*17.5=175

So 175 is our area. But we can't forget about units! Since this is area and we multiplied our units together, our units would be squared. That means our answer is <u>175 square feet</u>.

PERIMETER

The formula for the perimeter of a rectangle is: 2(w+l)

We can plug our dimensions into the formula: 2(10+17.5)=55

So 55 is our perimeter. Of course, we can't forget about our units. Because this is perimeter, we only added our units together, so they don't change. That means our answer is <u>55 feet</u>.

3. If Earth was 10 times farther away from the sun than it is now, which planet would it be closest to? (Assume all the planets
Valentin [98]

Real distance of Earth from Sun . . . 93 million miles
                                                 =  1 AU (Astronomical Unit)

10 times farther . . . . . 930 million miles  =  10 AU

Compare:

==>  Saturn . . .  9.5 AU
==>  Uranus. .  19.2 AU

If Earth were 10 times farther from the sun than we really are,
then our planet would be just barely past Saturn ... about 10%
of the way from Saturn to Uranus.

Please help<br> i really need help<br> only answer if u know the answer<br> and no links please
ehidna [41]

Answer:

The correct answer is 17.96875 or approximately 18 inches.

Step-by-step explanation:

Since the ratio of the model truck to the real truck is 5:64, and the length of the truck is 230 inches, that means the length of the model truck would be \frac{5}{64} * 230 = \frac{575}{32} = 17.96875 ≈ 18 inches.
