Answer:

$542

Step-by-step explanation:

we know that

The equation of a exponential decay function is given by

y=a(1-r)^x

where

y is the value of the lawnmower

x is the time in years

a is the initial value

r is the rate of change

we have

a=\$600\\r=2\%=2/100=0.02

substitute

y=600(1-0.02)^x

y=600(0.98)^x

For x=5 years

y=600(0.98)^5=\$542

Round to the nearest tenth.
inessss [21]

Answer: Angle A = 53.9 degrees

Step-by-step explanation: We have a right angled triangle with two sides clearly given and one angle to be calculated. If the angle to be calculated is angle A, then having angle A as our reference angle, line AC (10 units) is the adjacent, line CB is the opposite while line AB (17 units) is the hypotenuse. Having been given the adjacent and the hypotenuse, we can now use the trigonometric ratio as follows;

CosA = adjacent/hypotenuse

CosA = 10/17

CosA = 0.5882

By use of the calculator or table of values,

A = 53.97

Approximately to the nearest tenth,

A = 53.9 degrees

A halloween assorted bag of candy contains 4 Snickers, 2 packages of M&M's, & 3 Butterfingers. What is the probability o
andrezito [222]

Answer:

0.07

Step-by-step explanation:

First, add up all the numbers. This will be the denominator.

4+2+3=9

There are 9 pieces of candy.

Since you are randomly choosing two times you will have to multiply two fractions.

There are \frac{2}{9} M&M's, and \frac{1}{3} Butterfingers (You simplify)

Now you multiply these.

\frac{2}{9}×\frac{1}{3}=\frac{2}{27}

Now make this into a decimal. To do this divide 2 and 27. which is approximately 0.07.

Canned dog food is on sale for 20% off the original price. What is the discount of a can if the original price is $1.35?
konstantin123 [22]

Answer:

1.08

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 1.35 × 20/100

Discount = 27/100

You save = $0.27

Final Price = Original Price - Discount

Final Price = 1.35 - 0.27

Final Price = $1.08


Hope this helps (:

Is the percent increase from 50 to 70 equal to the percent from 70 to 50explain.
Mrac [35]

Answer:

20/50=40%  So 50 to 70 percent increase is 40%.

20/70=about 28.57% decrease for 70 to 50.

So they aren't the same because the hundred percent are different numbers in this case.

Answer:

1/2

Step-by-step explanation:

Let's pick two points and find the slope inbetween them.

I'll pick (2,1) and (0,0).

Remember that slope = change in y / change in x.

slope = 1-0 / 2-0 = 1/2
