Answers

Answer:

y = 1/3x - 3

Step-by-step explanation:

Subtract 2x on both sides

6y = 2x - 18

Isolate y by dividing 6 on both sides

y = 2/6x - 3

Simplify.

y = 1/3x - 3

To the nearest cent, how much interest will he earn in 2 years?

Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.

Answers

Answer: $8.40

Step-by-step explanation:

The problem states that Scott has deposited $40 and is earning 10% interest, annually. It asks how much interest he will earn in 2 years to the nearest cent.

First, the formula given is B=p(1+r)^t. Since Scott deposits $40, 40 would be the starting amount, p.

B=40(1+r)^t

R is the interest rate: 10%. We plug in 0.10 instead of 10% because r is the interest rate, not the percentage.

B=40(1+0.10)^t

T is time: 2 years

B=40(1+0.10)^2

Now that we have the equation filled out, we plug this into a calculator.

48.4=40(1+0.10)^2

We know that the final amount is $48.40. Unfortunately, the question is asking how much interest is earned. To find that, you would subtract the Final-Initial to get the interest.

48.4-40=8.4

Answers

Answer:

1. Given

2. Addition property of inequality

3. Division property of inequality

4. Square root property

Step-by-step explanation:

The first equation is always going to be the given since it hasn't been solved yet, on the next step you had to get rid of the 1 so you had to add 1 to both sides, this is called addition property of inequality, then to isolate the x you had to divide both sides by 4, this is called division property of inequality and lastly you had to do the opposite of squaring a number, which is taking the square root. Hope this helped.

Write the equation of a line that passes through the origin and is perpendicular to the line whose equation is 12x - 4y = 24.

Answers

Answer:

y=-1/3x

Step-by-step explanation:

Let's convert this to slope intercept form:

12x-4y=24

-4y=-12x+24

y=3x-6

Therefore, the slope of this line is 3, so the perpendicular line to this would have slope -1/3. Therefore, the slope of the line would be y=-1/3x. Hope this helps!

A lawn sprinkler located at the corner of a yard is set to rotate 50 degrees and project water out 30.0 feet. To the nearest tenth of a foot, what area of the lawn is watered by the sprinkler

Answers

Answer:

Area of the lawn is watered by the sprinkler is 392.75 ft²

Step-by-step explanation:

As the  lawn sprinkler  rotate 50 degrees when it project water out, it makes an arc from the corner where it is located.

The area of the lawn in which the water sprinkles, forms a sector with an angle of 50 degrees and radius of 30.0 feet.

[tex]Area \ of \ sector = Area \ of \ lawn= \frac{\theta}{360} \pi r^2\\\\ Area \ of \ lawn= \frac{50}{360} \pi (30)^2 = 392.75 \ ft^2[/tex]

Therefore, area of the lawn is watered by the sprinkler is 392.75 ft²

Does the equation y = x/2
represent a proportional relationship?
Yes, because the coefficient of x is positive
No, because it is not in the form y=kx
No, because its graph does not pass through the origin
Yes, because its graph is a line that passes through the origin
QUICK PLEASE!! TY!

Answers

Answer:

D) Yes, because its graph is a line that passes through the origin

--------------------------

The form of the equation of a proportional relation is:

y = kx, where k is the coefficient.

In the given case y = 1/2x,  where k = 1/2, so it represents proportional relationship.

Answer choices:

A. Yes, because the coefficient of x is positive.

False, as the coefficient  of x can be negative too.

B. No, because it is not in the form y = kx.

False, as it is in the form of y = kx.

C. No, because its graph does not pass through the origin.

False, graph passes through the origin.

D. Yes, because its graph is a line that passes through the origin

True, the graph passes through the origin; y = 0 at x = 0 regardless the value of k.

A day of the week is randomly chosen What is the probability of choosing Monday or a day that starts with the letter
S?
P(Monday)
P(starts with 5)
P(Monday or starts with )​

Answers

Answer:

Well, P(Monday)= 1/7 = 14.3%

P(starts with S)= 2/7 = 28.6%

P(Monday or starts with S)= 3/7 = 42.9%

Step-by-step explanation:

Have a good day!!!

The probability of choosing Monday is,

P = 1 / 7

And, the probability of choosing starts with S is,

P = 2/7

And, the probability of choosing Monday or starts with S is,

P = 3/7

What is mean by Probability?

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Given that;

A day of the week is randomly chosen.

Since, Number of days in a week = 7

Hence, the probability of choosing Monday is,

P = 1 / 7

And, the probability of choosing starts with S is,

P = 2/7

So, the probability of choosing Monday or starts with S is,

P = 2/7 + 1/7

P = 3/7

How many times larger is the volume of a cone if the radius is multiplied by 6?

Answers

Answer:

36 times larger.

Step-by-step explanation:

V= [tex]\pi *r^{2}*\frac{h}{3}[/tex] is the original volume of a cone formula.

If the radius is multiplied by 6 the new formula is:

V= [tex]\pi *(6x)^{2} * \frac{4}{3}[/tex]

Which is simplified to:

V= [tex]\pi *36r^2*\frac{h}{3}[/tex]

The only difference between the simplified formula and the original is the *36 so the new volume is 36 times larger when the radius is multiplied by 6.
