Answer:

$68

Step-by-step explanation:

First, find out what 15% of $80 is. 15% as a decimal is 0.15. Multiply 0.15 and 80 together.

0.15 x 80 = 12.

Now, subtract 12 from the original price, 80.

80 - 12 = 68.

Answer:

I can solve with 2 methods:

I. Because the discount is 15 % of 18 $ , the price will be (100-15=85) 85 % of 18 $

18*85/100= 15,3 $ ( the sale price)

II. The discount is 15 % of 18$

15*18/100= 2,7$ ( the discount)

then I decrease it from the regularly price

18$-2,7$=15,3 $ (the sale price)

Personally I believe the first is an easier method.

I hope you understand and you can apply this in every similary problem.

If I varies inversely with R and I = 0.25 when R = 18, which equation should be used to show this relationship?

pashok25 [27]

Inverse relationships are of the form xy=k or if you prefer y=k/x so to find the constant we can say:

18(0.25)=k=4.5

So you could say: IR=4.5 or I=4.5/R

For the following exercises, evaluate the expressions, given functions f, g, and h:

sertanlavr [38]

Answer:

- 16

Step-by-step explanation:

Evaluate f(2) by substituting x = 2 into f(x) , that is

f(2) = 3(2) - 3 = 6 - 3 = 3

Evaluate g(- 1) by substituting x = - 1 into g(x) , that is

g(- 1) = 8 - (- 1)² = 8 - 1 = 7

Thus

4f(2) - 4g(- 1)

= 4(3) - 4(7)

= 12 - 28

= - 16

3/4 3√128. simplify? kindly

lisov135 [29]

Answer: 3∛2

Step-by-step explanation:

First, factor 128 .... you need three common factors to bring one on the outside of the radical.

$\dfrac{3}{4}\sqrt[3]{128} \\\\\\=\dfrac{3}{4}\sqrt[3]{4\cdot 4\cdot 4\cdot 2} \\\\\\=\dfrac{3}{4}\cdot 4\sqrt[3]{2} \\\\\\=\large\boxed{3\sqrt[3]{2} }$

How can you use a coordinate plane to solve perimeter and area problems? Please help me

lana66690 [7]

Well, you can do
area=legnth times widht
perimiter=2(legnth+width)
then you just subsitute x for legnth and y for width then solve
area=xy
perimiter=2(x+y)
then graph and find the intersection to find the solution
