Using the formula for simple interest and the given values, find I. P= $300; r = 8%; t= 6 years; I = ? 1=$0 TrueCar Enter your a

Mashutka [201]

Answer: $144

Step-by-step explanation:

The formula to calculate the simple interest is given by :-

$\text{S.I.}=Prt$

Here, P - Principal amount, r - rate of interest and t is time (Generally in years).

Given : P= $300; r = 8%=0.08 ; t= 6 years

Now, the using the above simple interest formula , we have

$\text{I}=300\times0.08\times6\\\\\Rightarrow\ \text{I}=\$\ 144$

Therefore , the simple interest = $ 144.

The monthly cost in dollars of a long distance phone plan is a linear function of the total calling time in minutes. The monthly

Deffense [45]

Answer:

The monthly cost for 45 minutes is $18.42

Step-by-step explanation:

Let

x -----> the total calling time in minutes

y ----> the monthly cost in dollars

we have the ordered pairs

(42,18.15) and (90,22.47)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{22.47-18.15}{90-42}$

$m=\frac{4.32}{48}$

$m=\$0.09\ per\ minute$

step 2

Find the linear equation in point slope form

$y-y1=m(x-x1)$

we have

$m=0.09\\(x1,y1)=(42,18.15)$

substitute

$y-18.15=0.09(x-42)$

step 3

Find the monthly cost for 45 minutes of calls

For x=45 min

substitute the value of x in the linear equation and solve for y

$y-18.15=0.09(45-42)$

$y-18.15=0.09(3)$

$y-18.15=0.27$

$y=0.27+18.15$

$y=18.42$

therefore

The monthly cost for 45 minutes is $18.42

How would I write 21/8 as a mixed number?

matrenka [14]

Divide 21 by 8. and then whatever the reminder comes will go as the whole number
and the reminder will be the numerator and the number 8 will be the denominator.
the answer is 2 5/8
2 is the whole number, 5 is the numerator and 8 is the denominator

What is the perimeter of triangle DEF

LuckyWell [14K]

Remember that A squared plus B squared equals C squared.

Since sides F_D and D_E are both 3, the answer cannot be 4.2 or 2.4.

SO basically you just add 3 + 3 = (The side F_E, which you can get by putting numbers in the formula), you should get your answer.

3² + 3² = Line EF²
9 + 9 = Line EF²
18 = Line EF²
√18

You get the idea. Hope this helps!
