Answer:

330

Step-by-step explanation:

If d = distance, t = time, and s = speed, then the relationship between the 3 is s * t = d.

Solve for speed by dividing the distance over the time, s = d/t. Then, plug in the speed which in this case is 55 mph and then multiply by the time of 6 hours.

With an 18% discount, Joan was able to save $13.23 for a coat. What was the original price of the coat?
strojnjashka [21]
Hi there!

First we need to realise that the 18% discount equals John's savings. Therefore 18% of the original price is $13.23.

When we know 18% of the price, we can also find 1% of the total price.

18% = $13.23
Divide both sides by 18.

1% = $0.735
To find the total price, which equals 100%, we know only need to multiply both sides by 100.

100% = $73.50.
Therefore, the original price for the coat is $73.50.

A granite block in the shape of a right rectangular prism has dimensions 30 centimeters by 40 centimeters by 50 centimeters. The
Leno4ka [110]

Answer:

The mass of the block is 168,000\ g

Step-by-step explanation:

we know that

The density is equal to the mass divided by the volume

step 1

Find the volume of the granite block

we know that

The volume of a rectangular prism (granite block) is equal to

V=LWH

substitute the values

V=(30)(40)(50)=60,000\ cm^{3}

step 2

Find the mass of the block

D=\frac{m}{V}

we have

V=60,000\ cm^{3}

D=2.8\frac{g}{cm^{3}}

substitute the values and solve for the mass

2.8=\frac{m}{60,000}

m=2.8*60,000=168,000\ g
