In this question, we're trying to find how many hours Maria can rent the boat for.

We know that the boat rental costs $60 per hour

We also know that she has to pay a one-time fee of $10 for a safety course

Turn this into a equation:

y = 60x + 10

However, she doesn't want to spent no more than $230. Add that to your equation

230 = 60x + 10

Solve the equation to see how many hours she can rent the boat for.

230 = 60x + 10

Subtract 10 from both sides

220 = 60x

Divide both sides by 60

3.67 = x

Since the boat can ONLY be rented by whole hours. With the money Maria has, she can only rent the boat for 3 hours.

Answer:

3 hours

Help me please thank you.

The correct answer is A: 2.

The slope compares the vertical change (the rise) to the horizontal change (the run) when moving from one fixed point to another along the line.

If you look at your graph, it takes 2 units up and 1 unit to the right in order to get to the next point on the line.

Therefore, the slope of the line is 2/1, or simply 2. It has a positive value because the line is sloping upward.

Answer:

34

Step-by-step explanation:

Angles 3 and 7 are corresponding angles. When the lines defining the base of the corresponding angles are parallel (as in this case where a is parallel to b), then the angles are equal.

That's the heavy duty definition. It just means that corresponding angles in parallel lines are equal.

So if <3 = 34 degrees, then <7 = 34 degrees.

Write the expression 44(4–7)(4) using a single exponent.
Ghella [55]
<h3>The given expression as single exponent is:</h3>

4^4 \times 4^{-7} \times 4 = 4^{-2}

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

4^4 \times 4^{-7} \times 4

In exponents,

When the base is same, exponents can be added

Which means,

a^m \times a^n = a^{m+n}

Therefore,

4^4 \times 4^{-7} \times 4 = 4^{4-7+1}\\\\Simplify\\\\4^4 \times 4^{-7} \times 4 = 4^{-3+1} \\\\4^4 \times 4^{-7} \times 4 = 4^{-2}

Thus the given expression as single exponent is:

4^4 \times 4^{-7} \times 4 = 4^{-2}
