100 is smaller than 110 by how many percent?

2 answers:

8 0

Compare 100 to 110, and see that to go from 100 to 110 is a 10% increase, but to go from 110 back down to 100 is a 9.09% decrease not a 10% decrease

Answer:

9.09%

Any percent increase or decrease can be determined by using the process:

change/original ×100%

The change is the amount of increase or decrease, simply subtract:

Bigger value - smaller value

Step-by-step explanation:

in this case 110-100

----------- ×100

110

=100/11 = 9.09 %

Last year, I had 92 APES students and this year I will have 63 APES students. By what percentage will the population of APES stu

Reptile [31]

Answer:

31.52% increase (decrease)

Step-by-step explanation:

To find the decrease in the percentage of students from the previous year to the current year, you must establish a baseline to be your maximum (100%). For this we'll use the 92 students. From here, we need the current 63 students to establish the current percentage.

Simply:

63/92 == .6848 == 68.48%

So our current percentage of students is 68.48%. We want the decrease of the students compared to the previous percentage so we'll need to do the maximum minus the current to get the change (or the decrease).

100% - 68.48% = 31.52%

Thus, the population increase (decrease) for this year is 31.52%.

A zip line starts 28 feet in the air and

goldfiish [28.3K]

Given:

A zip line goes from 28 feet to 11 feet in the air. The angle of depression is 85°.

To find:

The length of the zip line where there is no rider.

Solution:

A right-angled triangle can be formed using the given data.

The difference in height between the start and end of the zipline is $28-11=17$ . The angle of the triangle is 85°.

Assume the zip line is x feet long.

The adjacent side of the triangle measures 17 feet, the hypotenuse of the triangle measures x feet, and the angle of the triangle is 85°.

To determine x, we calculate the cos of the given angle.

$cos \theta = \frac{adjacentside}{hypotenuse} .$

$cos 85 = \frac{17}{x} , x = \frac{17}{cos85}, cos85= 0.0871.$

$x = \frac{17}{0.0871} = 195.1779.$

Rounding this off, we get the length of the zip line when there is no rider is 195.18 feet long.

If the measures of five interior angles of a hexagon are 133 , 111 , 92 , 153 , and 109 , what is the measure of the other inter

Burka [1]

The sum of the interior angles of a hexagon is equal

$6\cdot\left(180^o-\dfrac{360^o}{6}\right)=6\cdot(180^o-60^o)=6\cdot120^o=720^o$

Calculatle the measure of the other interior angle:

$720^o-(133^o+111^o+92^o+153^o+109^o)=720^o-598^o=122^o$
