the third option

because 1/3 is not equal to three

where as if we replace the x with one in all the other we would find that the equation is correct.

Explain why percents are rational numbers.

levacccp [35]

<span>Yes since percents can be decimals and these decimals can be illustrated as fractions hence, vice-versa.

80%= 0.8 = 4/5

A rational number is any number or numerical value which can be possibly stated in a fraction form of numbers, it basically has a numerator and denominator. Furthermore, the values of the numerator and denominator is integers and doesn’t equal to 0. In this given case of 8 over 5 or 8/5 this fractional number can still be expressed in a standard numerical form with a decimal as 1.6 without repeating decimal values. Unlike irrational numbers which is not possible, take for instance 3.1416… and so on which cannot be “fractionized”.<span>

Please view picture. Also please tell mehow you got the answer

Have a look at the image attachment. I've added the points A, B, C, D such that
A = base of the diving board pole, or location of the pool deck
B = the location 1.6 meters directly above point A
C = location of the person's eyes
D = diving board location
The goal is to find the length of segment AD

We are given
AB = 1.6
BC = 3.67
what we want to find is
BD = x

Due to the fact we have similar right triangles ABC and CBD, we can form the proportion below and solve for x
AB/BC = BC/BD
1.6/3.67 = 3.67/x
1.6*x = 3.67*3.67
1.6*x = 13.4689
1.6*x/1.6 = 13.4689/1.6
x = 8.4180625

So BD is 8.4180625 meters
Use this to find the length of AD
AD = AB + BD
AD = 1.6 + 8.4180625
AD = 10.0180625
which rounds to 10.0 meters when rounding to the nearest tenth (one decimal place)

I’ve been on vacation and am struggling with this chapter. I came up with a word problem but am not sure how to solve it. Thank

Answer:

3 1/3

Step-by-step explanation:

So first turn 1 1/2 into a improper fraction-- which is 3/2

Then divide- to divide you need to flip the fraction and multiply

so you get 5/1*2/3 which equals 10/3 which is equal to 3 1/3
