Hello!

to solve this equation, you have to find the percentage of defects out of the total amount of jeans. if there are 300 pairs of jeans with 8 faulty pairs, then the percentage of defects would be 2.666(etc). 2.666(etc) percent of 3000 is roughly 80 pairs of defective jeans.

therefore your final answer would be 80 pairs of jeans!

Tasya [4]

Answer:

Rate = 6.56%

Step-by-step explanation:

Principal (P) = $5000

Interest (I) = $6312

Time (T) = 4 years

Rate (r) = ?

This question is involves simple interest and with the formula, we can easily plug in the values to find the rate.

S.I = P(1 + rt)

S.I = simple interest

P = principal

R = Rate

T = Time

6312 = 5000(1 + r*4)

6312 = 5000 + 5000*4r

6312 - 5000 = 20000r

1312 = 20000r

r = 1312 / 20000

r = 0.0656

Rate are calculated in percentage hence we'll multiply it by 100

R = 6.56%

Olin [163]
First you find P which would be 16+17+17 which equals 50. Then you find B which is 1/2•16•15 which equals 120. Next you write the formula which would look like 50(20)+2(120) which equals 1240!

Answer:

\dfrac{49}{4} = 12.25

Step-by-step explanation:

4^{x-1} =

= (2^2)^{x - 1}

= 2^{2(x - 1)}

= 2^{2x - 2}

= 2^{x + x - 2}

= 2^x \times 2^x \times 2^{-2}

= 7 \times 7 \times \dfrac{1}{2^2}

= \dfrac{49}{4} = 12.25

Linear functions can be used to find the price of a building based on its floor area below are two of these functions,
Alborosie

Answer:

Part A) see the explanation

Part B) see the explanation

Part C) see the explanation

Step-by-step explanation:

The complete question in the attached figure

Part A) Find and compare the slopes

we have

Function 1

y=40x+15,000

This is a linear equation in slope intercept form

y=mx+b

where

y is the price of the building in thousands

x is the floor area in square foot

m is the slope

b is the y-intercept

we have

m=\$40\ per\ ft^2

Function 2

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

take two points from the data in the table

(400,32,000) and (700,56,000)

<u><em>Remember that the price in the table is in thousands</em></u>

substitute

m=\frac{56,000-32,000}{700-400}

m=\$80\ per\ ft^2

The slope of the Function 2 is greater than the slope of the Function 1

The slope of the Function 2 is two times the slope of the Function 1

Part B) Find and compare the y-intercept

we know that

The y-intercept is the value of y when the value of x is equal to zero

Function 1

y=40x+15,000

For x=0

y=40(0)+15,000=\$15,000

Function 2

Find the equation in point slope form

y-y1=m(x-x1)

we have

m=80\\point\ (400,32,000)

substitute

y-32,000=80(x-400)

Convert to slope intercept form

isolate the variable y

y-32,000=80x-32,000\\y=80x

For x=0

y=80(0)=0

The y-intercept of the function 1 is $15,000 and the y-intercept of the function 2 is zero (the line passes through the origin)

Part C) Describe each function as proportional or non proportion

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

so

Function 1

y=40x+15,000 -----> is a non proportional linear function (because the line has a y-intercept)

Function 2

y=80x ----> is a proportional linear equation (the line passes through the origin)
