Jacob sells homemade skateboard decks for a profit of $27 per each one. He is considering switching to a new type of material that will increase his profit (y = 32x0) (where x is the number sold and y is the amount of profit).

How many more dollars will Jacob earn on each skateboard deck if he switches to the new material?
(Please Explain)

Answers

Answer:

I believe it is 32

Step-by-step explanation:

I think this because in your equation it says (y=32x) which 32 will mean how much he is charging for each skateboard, x will be how many he sells, and y would be how much he makes from selling them. So if he sold 2 skateboards you would do.. 32 x 2 which equals 64 soo that would be (64=32x2) so it is 32

Jacob will earn more for each skateboard deck if he switches to the new material is $5.

What is profit?

When something or the cost of manufacturing an object is less than the selling price of the object, then you get a profit.

As it is given that Jacob will increase his profit by 32x where x is the number sold means he will get $32 if he sold one product (32×1).

Before, he gets  a profit of $27 if he sold one skateboard, so,

Let Jacob will earn y amount more than the current material,

y = Profit in new material - Profit in old material

y = 32 - 27

y = $5

Therefore, Jacob will earn more for each skateboard deck if he switches to the new material is $5.

Kevin walked Three-fourths of a mile in 12 minutes. Assuming he walked at a constant speed the entire time, which expression can be used to determine the distance he walked each minute?
12 divided by three-fourths
12 times three-fourths
Three-fourths divided by 12
Four-thirds divided by 12

Answers

Answer:

Your answer would be C.

Step-by-step explanation:

The expression that can be used to determine the distance he walked each minute is x = 12/(3/4) miles option (A) is correct.

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

Kevin walked Three-fourths of a mile in 12 minutes. Assuming he walked at a constant speed the entire time.

As we know,

The distance = speed x time

Speed is constant

distance ∝ time

3/4 ∝ 12

1 ∝ x

Here x is the distance traveled each minute

3/4 = 12/x

Or

x = 12/(3/4)

1/4 = 4/x

x = 16 miles

Thus, the expression that can be used to determine the distance he walked each minute is x = 12/(3/4) miles option (A) is correct.

A conversion table indicates that 1 mile is 1.6 km. With this conversion rate, is the speed limit greater than or less than 65 mph? Explain.

Answers

greater because 1.6 is larger than 1

Answer:

higher than

Step-by-step explanation:

The speed limit is 110 km hour and there are 1.6 kilometers in a mile. This means that there are 110 ÷ 1.6 miles per hour:

110 km hour÷1.6 km mile=110÷1.6 miles hour.

We can find 110 ÷ 1.6 using long division and it is 68.75. So the speed limit  is higher than 65 mph

Answer:

-3

Step-by-step explanation:

The y intercept (when already written in slope-intercept form) is on the side of the equation without the actual variable y. The number with x is the slope. In this specific equation, the slope is 4 because it is with the variable x, and the y intercept is the other number, -3. The 3 is negative because subtraction signs are actually negative signs too.
