It cost $0.25 to use a dryer at a laundromat for 15 minutes. The expression

0.25m ÷ 15

represents the cost, in dollars, of using a dryer for m minutes. What is the cost to use the dryer for 120 minutes?

Answers

Answer 1

[tex]\Large\boxed{\tt Answer:~2 ~dollars}[/tex]

[tex]\tt Step-by-step~explanation:[/tex]

See how many times 15 can go into 120.

[tex]\tt \frac{120}{15} =8[/tex]

If 15 • 8 is 120, then the cost would have to multiply by 8.

[tex]\tt 0.25*8= 2[/tex]

It costs $2.00 to use the dryer for 120 minutes.

We can also use the equation to help. We plug in 120 for m and solve.

[tex]\tt 0.25(20)=30\\30 \div 15 = 2[/tex]

We still end up with the same result: $2.00 for 120 minutes.

Each statement describes a transformation of the graph of y = x. Which statement correctly describes the graph of y = x + 10?

A. It is the graph of y = x translated 10 units to the right.
B. It is the graph of y = x where the slope is increased by 10.
C. It is the graph of y = x translated 10 units up.
D. It is the graph of y = x translated 10 units down.

Answers

Answer:

C

Step-by-step explanation:

since it is the slope form y = mx+b

b = y axis

so in order to go up you have to translate upwards

Elsa took out a 2-year loan to buy a car at a 6% simple interest rate.

A. If she has to pay a total of $264 in interest, how much principal did she borrow to pay for the car?

B. How much did she end up paying for her car altogether?

Answers

Step-by-step explanation:

P = I / rt is the formula we're going to use.

P is the principle (which is what we're solving for)

I = the interest accrued over the specified amount of time (2 years)

r = the interest rate (6%)

t = the time specified (2 years)

Change the percent to a decimal. Place the decimal two places to the left to make 0.06.

P = 264 / 0.06(2)

P = 264 ÷ 0.12 = 2,200

Principal borrowed would be $2,200

A store manager combines trail mix that is 30% raisins with a trail mix that is 55% raisins. He makes 800lb of trail mix that is 40% raisins. How many pounds of each trail mix does the manager use?

Answers

Answer:

320 pounds of 55% raisins trail mix

480 pounds of 30% raisins trail mix

Step-by-step explanation:

Sorry, I can’t write how I got the answer. We just did it in class and decided to help... (Btw, sorry if I’m too late)

The store manager mixed 320 pounds of 55% raisins trail mix and 480 pounds of 30% raisins trail mix.

Given that,

A store manager combines a trail mix that is 30% raisins with a trail mix that is 55% raisins.

He makes 800lb of trail mix that is 40% raisins.

We have to determine,

How many pounds of each trail mix does the manager use?

According to the question,

Let, x = pounds of trail mix 30% raisins

y = pounds of trail mix 55% raisins

The distributor wants to make 800 pounds of trail mix, thus:

x + y = 800  

The mix must be 40% raisings as a combination of x and y, thus:

30x + 55y = 40 × 800

30x + 55y = 32,000

Divided by 5 the equation

6x + 11y = 6400

Solving both the equation

[tex]x + y = 800\\\\x = 800 -y\\[/tex]

Substitute the value of x in equation 2,

[tex]6x + 11y = 6400\\\\6 (800-y) + 11y = 6400\\\\4800 - 6y +11y = 6400\\\\5y = 6400-4800\\\\5y = 1600\\\\y = \dfarc{1600}{5}\\\\y = 320[/tex]

Substitute the value of x in equation 1

[tex]x + y = 800\\\\x + - 800 -y\\\\x = 800-320\\\\x = 480[/tex]

Hence, The store manager mixed 320 pounds of 55% raisins trail mix and 480 pounds of 30% raisins trail mix.

Find all solutions to the equation $x^2 - 7x = 30$. If you find more than one, then list the values separated by commas. If the solutions are not real, then they should be written in $a + bi$ form.

Answers

Answer:-3, 10

Step-by-step explanation:

Subtracting 30 from both sides gives x^2 - 7x - 30 = 0. The quadratic factors as

(x - 10)(x + 3) = 0, so the solutions are x = 10 and x = -3.

Instead of factoring, we also could have applied the quadratic formula with a = 1, b = -7, and c = -30:

The solutions to the equation x² - 7x = 30 are -3 and 10.

What is a solution?

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

x² - 7x = 30

x² - 7x - 30 = 0

Middle-term factorization.

x² - (10 - 3)x - 30 = 0

x² - 10x + 3x - 30 = 0

x(x - 10) + 3(x - 10) = 0

(x + 3) (x - 10) = 0

x + 3 = 0

x = -3

x - 10 = 0

x = 10

Thus,

The solutions are -3 and 10.

He added all the numbers as they were a decimal number, with the kilometers traveled by Bus and Car being 2 to the left than where it should have been.

How I found it:

Converting 7 and 2.3 into a decimal with the decimal place two to the left.

7 becomes 0.07

2.3 becomes 0.23

I added this to the kilometers traveled by train(which is 19.955km).

19.955km + 0.023 + 0.07 = 19.985

19.985 being the value for answer A.
