A school had 1,200 students last year and only 1,080 students this year. What was the percentage decrease in the number of stude
jeyben [28]
Answer: 10%

First off, you need to divide 1200 with 1080.

1200 - 1080 = 120.

Next, divide 120 with the original number.

120 / 1200 = 0.1

Then, multiply 0.1 with 100.

100 x 0.1 = 10

Finally, add a % at the end.

10 -> 10%

So in summary, your answer is 10%

Tacoma's population in 2000 was about 200 thousand, and has been growing by about 8% each year. If this continues, what will Tac
Anestetic [448]

Answer:

Tacoma's population in 2014 will be 587,439 people

Step-by-step explanation:

we know that

The equation of a exponential growth function  is given by the formula

y=a(1+r)^x

where

y is Tacoma's population in thousand

x is the number of years since 2000

r is the rate of change

a is the initial value

we have

a=200\\r=8\%=8/100=0.08

substitute

y=200(1+0.08)^x

y=200(1.08)^x

what will Tacoma's population be in 2014?

Find the value of x

x=2014-2000=14\ years

substitute the value of x

y=200(1.08)^{14}=587.439\ thousand

therefore

Tacoma's population in 2014 will be 587,439 people

Length of KL is 17 units

Given that;

L is mid point of KM

KL = 2x - 3

LM = x + 7

Find:

Length of KL

Computation:

We know that,

L is mid point of KM

So,

KL = LM

2x - 3 = x + 7

2x - x = 7 + 3

x = 10

So,

Length of KL = 2x - 3

Length of KL = 2(10) - 3

Length of KL = 20 - 3

Length of KL = 17 units
