Only do question 15<br><br> 50 points<br><br> Topic: Percentage
Varvara68 [4.7K]

Answer:

see below

Step-by-step explanation:

The total number of trees is

567+324+156+89+678 =1814

Percent fir = 567/1814 = .312568908=31.26 %

Percent pine = 324/1814 = .178610805=17.86%

Percent larch = 156/1814 =.085997795=8.60%

percent cedar = 89/1814 =.049062845=4.91%

Percent hemlock = 678/1814 = .373759647=37.38%

The total should be 100 %

31.26+17.86+8.60+4.91+37.38=100.01  ( rounding error because we rounded to the hundredths place)

What change of percent is 12 inches to 36 inches
Citrus2011 [14]
%change=100(final-initial)/initial

You can plug in your values...if you meant initial=12 and final=36...

%change=100(36-12)/12=200%

Since it is positive, that is a 200% increase.

Twice a year for 15 years, Warren Ford invested $1,700 compounded semiannually at 6% interest. What is the value of this annuity
-BARSIC- [3]

The value of Warren Ford annuity due is $80,878.21

Define Future Value of an Annuity.

The future value of an annuity is the value of a group of recurring payments at a certain date in the future, assuming a particular rate of return, or discount rate. The higher the discount rate, the greater the annuity's future value.

Given,

Payment fund semiannually is = $1,700

Rate = 6% or 0.06

Time = 15 years

The future value is,

FVₙ =PMT( (1+i/m)ⁿ - 1 ) / (i/m) )

Where,

PMT = $1,700

i = 0.06

m = 2

n = 15 * 2 = 30 periods

Now, plug in the values

FV₃₀ =  PMT ( (1 + 0.06/2)³⁰ - 1 ) / (0.06/2) )

       = $1,700( (1.03)³⁰ - 1 ) / (0.03) )

       ≈ $80,878.2067 or $80,878.21

Hence, the value of Warren Ford annuity due is $80,878.21

A train covers 165 km in 1.5 hours. Find the constant variation.
sdas [7]

Answer:

110

Step-by-step explanation:

To find the constant of variation, divide the number of km by the number of hours:

165/1.5

= 110

This means that the speed of the train is 110 km per hour.

So, the constant of variation is 110.
