Percent of change from 125cm to 87.5cm

Answers

Answer 1

Answer:

Answer:

Percentage change from 125cm to 87.5cm is 30% decrease.

Step-by-step explanation:

Percentage change of a to b is given by

$\texttt{Percentage change =}(b-a)/(a)* 100$

Here we have a = 125 and b = 87.5

Substituting

$\texttt{Percentage change =}(87.5-125)/(125)* 100=(-37.5)/(125)* 100=-30\%$

Percentage change from 125cm to 87.5cm is -30%.

That is 30 decrease.

Percentage change from 125cm to 87.5cm is 30% decrease.

Answer 2

Answer: Percent Change from 125cm to 87.5cm

% Change = (87.5 - 125) / 125 * 100%

   = -37.5 / 125 * 100%

   = -0.3 * 100%

   = -30 %

The percent change is -30 % or 30% decrease.

Answer:

J. $-(1)/(36)$ , $(1)/(216)$ , $-(1)/(1296)$

Step-by-step explanation:

We are given the following geometric sequence and we are to find its 8th term:

$-36, 6, -1, (1)/(6),...$

Here $a_1=-36$ and common ratio $(r) = (-1)/(6)=(-1)/(6)$ .

The formula we will use to find the next three terms is:

nth term = $a_1 * r^((n-1))$

5th term = $-36 * (-1)/(6)^((5-1))$ = $-(1)/(36)$

6th term = $-36 * (-1)/(6)^((6-1))$ = $(1)/(216)$

7th term = $-36 * (-1)/(6)^((7-1))$ = $-(1)/(1296)$

Answer:

Step-by-step explanation:

Find the common ratio r of the geometric sequence then multiply a term by r to obtain the next term

r = $(a_(2) )/(a_(1) )$ = $(6)/(-36)$ = - $(1)/(6)$

The next 3 terms are

$(1)/(6)$ × - $(1)/(6)$ = - $(1)/(36)$

- $(1)/(36)$ × - $(1)/(6)$ = $(1)/(216)$

$(1)/(216)$ × - $(1)/(6)$ = - $(1)/(1296)$

Determine whether the given point lies on the graph of the inequality. (-1,-3); -x-6y < 19.

in this case, is the point on the graph (yes or no)

Answers

-x - 6y < 19.

Point ( -1, -3) ⇔ x = -1 , y = -3
instead of the variables you need to put the values of x and y ( coordinates of the point )
- (-1) - 6*(-3) < 19

we calculate

1 + 18 < 19 record turns mushy

the point does not belong to the graph

Fifteen percent of an employee’s taxable income is collected each paycheck. Before taxes are removed from each paycheck, $350 of tax-exempt expenses is taken out. If the variable x represents the employee’s pay before tax-exempt expenses and taxes are removed, which expression represents the employee’s take-home pay after these deductions?

Answers

Answer:

0.85(x - 350)

Step-by-step explanation:

Here "x" represents the pay before tax.

Take exempted amount = 350.

The taxable amount = x - 350.

The tax rate = 15% = 15/100 = 0.15

Take home pay after the tax deduction = Taxable amount - tax

= (x - 350) - 0.15(x - 350)

Now we have to simplify this.

= (x - 350)(1 - 0.15)

= (x - 350)(0.85)

The employee’s take-home pay after these deductions= $0.85(x - 350).

Thank you.

Mrs. Ferguson looked at another hotel. She waited a week before she decided to book nights at that hotel, and now the prices have increased. The original price was $1589. The price for the same room and same number of nights is now $2075. What is the percent increase? Round to the nearest percent. Show your work. Will you plaes explain this ?

Answers

To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. If your answer is a negative number then this is a percentage decrease.

2075-1589=486

486*100/1589=30.58%

Rounding it we get,
30.6%
=31%
