One third of a number, z, added to one fifth of the same number is 3/5 . What is the number and why?

1 answer:

3 0

Let
z--------> the number

we know that
One third of a number, z, added to one fifth of the same number is 3/5
so
the equation that represents this sentence is
(1/3)z+(1/5)z=3/5
(5+3)z/15=3/5----------> 8z=9-------> z=9/8

therefore

the answer is the option
D) 9/8 , because the equation that represents this sentence is 1/3z+1/5z=3/5 .

Help please ! order the side lengths GH , HI , IG from least to greatest

jok3333 [9.3K]

Answer:

IH < IG < HG

Step-by-step explanation:

To solve this equation remember that angle measurements correspond with sides. So, the largest angle will be opposite of the longest side and the smallest angle will be opposite of the shortest side.

First, you need to find m<I; do this by subtracting 52 and 45 from 180. This means that m<I=83, making it the largest angle. Therefore, the angles, in order of least to greatest, are <G, <H, <I. So, to find the final answer, find the sides opposite of each of the angles. This means the answer is IH < IG < HG.

In kilometers, the approximate distance to the earth's horizon from a point h meters above the surface can be determined by evaluating the expression

$d= \sqrt{12h}$

We are given the height h of a person from surface of sea level to be 350 m and we are to find the the distance to horizon d. Using the value in above expression we get:

$d= \sqrt{12*350}=64.81$

Therefore, the approximate distance to the horizon for the person will be 64.81 km
