If the simple interest on $1,000 for 5 years is $300, then what is the interest rate?

pantera1 [17]

Answer:

6%/year

Step-by-step explanation:

Solving our equation

r = 300 / ( 1000 × 5 ) = 0.06

r = 0.06

converting r decimal to a percentage

R = 0.06 * 100 = 6%/year

The interest rate required to

accumulate simple interest of $ 300.00

from a principal of $ 1,000.00

over 5 years is 6% per year.

Laura can weed the garden in 1 hour and 20 minutes and her husband can weed it in 1 hour and 30 minutes. How long will they take

Harrizon [31]

<h2>Hello!</h2>

The answer is:

It will take 42.35 minutes to weed the garden together.

To solve the problem, we need to use the given information about the rate for both Laura and her husband. We know that she can weed the garden in 1 hour and 20 minutes (80 minutes) and her husband can weed it in 1 hour and 30 minutes (90 minutes), so we need to combine both's work and calculate how much time it will take to weed the garden together.

So, calculating we have:

Laura's rate:

$\frac{1garden}{80minutes}$

Husband's rate:

$\frac{1garden}{90minutes}$

Now, writing the equation we have:

$Laura'sRate+Husband'sRate=CombinedRate$

$\frac{1}{80}+\frac{1}{90}=\frac{1}{time}$

$\frac{1*90+1*80}{7200}=\frac{1}{time}$

$\frac{170}{7200}=\frac{1}{time}$

$\frac{17}{720}=\frac{11}{time}$

$\frac{17}{720}=\frac{1}{time}$

$\frac{17}{720}*time=1$

$time=1*\frac{720}{17}=42.35$

Hence, we have that it will take 42.35 minutes to weed the garden working together.

Have a nice day!

Answer:

Choice B.

Step-by-step explanation:

In a function, each x-coordinate can only appear in one single point. In a relation, if more than one point have the same x-coordinate, it is not a function.

Apply the vertical line test.

Imagine a vertical line starting at the left of the graph and moving to the right.

If the line in any position intersects more than one point of the relation, then the relation is not a function.

If the line in every position only intersects one point at a time, then the relation is a function.

Start with Choice A.

A vertical line starts at the left and moves right. It intersects point (-4, 3) by itself. Then it intersects point (-2, 1) by itself. When the vertical line gets to x = -1, it intersects two points, (1, -1) and (-1, 4). This means it is not a function.

Choice B.

Any vertical line in any position intersects at most one point at a time. Choice B is a function.

Choice C.

At x = -2 and at x = 2, a vertical line intersects two points. This is not a function.

Choice D.

At x = 0, a vertical line intersects two points. This is not a function.
