Answer:

So, the number that Lin multiplied by 7/8 MUST be less than 1. This is evident, as any positive number multiplied by a number less than 1 will decrease, doesn't matter if its a negative or positive number.

For a package to qualify for a certain postage rate, the sum of its length and girth cannot exceed 85 inches. If the girth is 63

tester [92]

Answer:

Length of package can be = 22 inches

Step-by-step explanation:

Given:

For a package to qualify for a certain postage rate, the sum of its length and girth cannot exceed 85 inches

To find length of package when girth of package is = 63 inches

Solution:

Let length of package be = $l$ inches

Let girth length of package be = $g$ inches

Sum of length and girth of package = $(l+g)$ inches

To qualify for a certain postage rate the sum of length and girth should not exceed 85 inches.

Thus, the inequality representing the situation can be given as:

$l+g\leq 85$

We are given girth of package is = 63 inches

So, inequality to find length would be:

$l+63\leq 85$

Subtracting both sides by 63.

$l+63-63\leq 85-63$

$l\leq 22$ inches

So, length should not exceed 22 inches in order to qualify.

Thus, the maximum length of package to qualify for the postal rate must be = 22 inches

Jacy has $1,000 to invest in either a fund that pays approximately 4.6% per year or in a savings account with an annual interest

Juli2301 [7.4K]

Answer:

S(x) = 0.046x + 0.018(1000-x)

Step-by-step explanation:

Given that:

A fund rate: 4.6% = 0.046
Saving account rate: 1.8% = 0.018

Let x is the amount Jacy invest in the fund so (1000-x) is the amount he invests in the savings account

So a polynomial function S(x) to represent the interest Jacy will earn in 1 year is:

S(x) = 0.046x + 0.018(1000-x)

Hope it will find you well.

Jace gathered the data in the table. He found the approximate line of best fit to be y = –0.7x + 2.36. What is the residual valu

sammy [17]

The answer
the table is

x 0 1 4 5 7
y 3 1 0 -2 -2

<span>the approximate line of best fit to be y = –0.7x + 2.36
so when the value of x=5, the residual value is

</span><span>y = –0.7(5) + 2.36 = -1.14 this is the actual value
the predicted value is -2 (for x=5)

and residual value formula is RS = y actual value - y predicted value

so RS = -1.14 - (-2) = 0.86
