Write each decimal as a percent and a fraction -0.04

Mathematics
1 answer:
Annette [7]3 years ago

Answer:

-4%   -1/25

Step-by-step explanation:

To convert a decimal to a percentage, multiply it by 100.

-0.04 * 100 = -4

To convert a decimal to a fraction, put the decimal as a fraction over 1 and multiply until the numerator (top number) is a whole number and then simplify.

\frac{-0.04}{1} x \frac{100}{100} = \frac{-4}{100}

-4/100 simplified = -1/25 <em>(because </em><em>4</em><em> goes into </em><em>100</em><em> 25 times)</em>

Using proportions, it is found that the speed of the runners are of 16 mph and of 20 mph.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount.

After 30 minutes, the runners are 2 miles apart, hence the second runner is 4 miles per hour faster than the second, that is:

v_2 = v_1 + 4.

The first runner's speed is 4/5 of the speed of the second runner, hence:

v_1 = \frac{4}{5}v_2

v_1 = \frac{4}{5}(v_1 + 4)

\frac{1}{5}v_1 = \frac{16}{5}

v_1 = 16

v_2 = 16 + 4 = 20

Hence, the speed of the runners are of 16 mph and of 20 mph.

Y=logxif y=10, then what is x
Kamila [148]
Assuming the logarithm is base 10, you have

y=10=\log_{10}x\implies 10^{10}=10^{\log_{10}x}\implies 10^{10}=x

A cone has a lateral area 100 pi and total surface area 136 pi. Find its radius.
cupoosta [38]

Answer:

Radius of the cone is 6 unit.

Step-by-step explanation:

Given:

Lateral Surface Area of Cone, LSA = 100π unit²

Total Surface Area of cone, TSA = 136π unit²

Let, r be the radius of cone.

According to the question,

Total Surface area = lateral surface area + Area of circle

136π = 100π + πr²

πr² = 36π

r² = 36

r = 6

Therefore, Radius of the cone is 6 unit.
