A gardener uses a wheelbarrow to move soil from a truck to his garden. On the first trip from the truck to the garden, the wheelbarrowis half-full of soil and the gardener applies a certain force to cause it to accelerate. On the second trip, the wheelbarrow is full of soil.
Although the gardener applies the same amount of force to the wheelbarrow, he cannot move it with the same rate of acceleration.
What should the gardener do to move the wheelbarrow at the same rate of acceleration for the second trip?
A. reduce the amount of soil by one-half and apply the same amount of force
B. keep the amount of soil the same and apply less force
C. reduce the amount of soil by one-quarter and apply the same amount of force
D. double the amount of soil, and apply less force

Answer 1

Answer:

Answer:

Step-by-step explanation:

it seems to me that if he wants the same rate of acceleration as the first trip, then he would need the same amount of soil as the first trip.

Therefore, he should reduce the amount of soil by one half and apply the same force. <====

Because the first time it was half full.....and since the second trip was all the way full, if he reduced it by one half, it would contain the same amount as the first trip....so he can then get the same rate of acceleration.

Answer 2

Answer:

Answer:

Step-by-step explanation:

According to Newton's second law of motion, an object with a larger mass requires more force to accelerate it at a certain rate than an object with less mass. This means that an object with a larger mass requires more force to accelerate.

To move the wheelbarrow at the same rate of acceleration for the second trip, the amount of soil must be the same as in the first trip. Since the gardener first filled only one-half of the wheelbarrow with soil, the gardener must reduce the amount of soil by one-half and apply the same amount of force.

Explain how to use a tape diagram to find 90% of 180

Answers

Using a tape diagram, we find that 90% of 180 is 162.

A tape diagram, also known as a bar model, is a visual representation used to solve mathematical problems. To find 90% of 180 using a tape diagram, follow these steps:

Step 1: Draw a tape diagram with a bar that represents the whole value, which is 180 in this case.

Step 2: Divide the bar into 10 equal segments, representing 100% of the value.

Step 3: Shade 9 out of the 10 segments to represent 90% of the value.

Step 4: Determine the value represented by the shaded segments. Since 9 out of 10 segments are shaded, the value is 9/10 of 180.

Step 5: Calculate the result. 9/10 of 180 is (9/10) * 180 = 162.

Therefore, using a tape diagram, we find that 90% of 180 is 162. This visual representation helps understand the concept of percentages and provides an intuitive way to solve the problem.

You must make a tape diagram going by 10 percents. 10, 20, 30... Then, put 180 over the 90 percent. Then, do 180 divide by 10 to find out 10 percent. That is 18. Then do 18 times 9 which is 162.

Also, you could make 90 a decimal. 0.90. 0.90 times 180 is 162.

What is the solution to 2(2w-6)=6(w-6)+14

Answers

2(2w-6)=6(w-6)+14
4w-12=6w-36+14
4w-12=6w-22
22-12=6w-4w
10=2w
w=10:2
w=5

$2(2w-6)=6(w-6)+14$

$4w-12=6w-36+14$

$4w-12=6w-22$

$-12=6w-22-4w$

$-12=2w-22$

$-12+22=2w$

$10=2w$

$10=2w/2$

$w=5$

Which of the following could represent the graph of f(x) = x4 + x3 – 8x2 – 12x?

Answers

The graph (B) represents the polynomial function f(x) = x⁴ + x³ – 8x² – 12x because the graph intersect at 0, -2, and 3option (B) is correct.

What is polynomial?

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

$\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n$

We have a polynomial function:

f(x) = x⁴ + x³ – 8x² – 12x

First, find the roots or zeros of the polynomial.

Using the factorization method:

We can write the above polynomial as:

f(x) = x(x³ + x² - 8x - 12)

f(x) = x(x + 2)(x + 2)(x - 3)

f(x) = x(x + 2)²(x - 3)

The zeros are:

x = 0

x = -2

x = 3

Thus, the graph (B) represents the polynomial function f(x) = x⁴ + x³ – 8x² – 12x because the graph intersect at 0, -2, and 3option (B) is correct.

Answer: 2

Step-by-step explanation:

How do you set up the equation?

Answers

This is asking for you to use the Pythagoras's theorem, which says that if you are given a height of a right triangle (h) and the length of that right triangle (L), then, the hypotenuse, or the distance between them (d), is:

$d^2 = h^2 + L^2$

Here, we are given that the height is 3m and the length is 5m. The distance, then will be given by:

$d = √(h^2+L^2)$

$d = √(3^2+5^2)$

$d = √(9+25) =√(16) =4$

So, the distance between the ladder and the bottom of the slide is 4 meters. Hope I could help! :)
