Hey there! :)

Answer:

1124.8 J.

Step-by-step explanation:

Given:

Distance: 25 meters.

Force: 70 N.

Direction: 50° with the horizontal.

Start by calculating the magnitude of the vector:

cos (50) = |x| / 70

70 · cos (50) = |x|

Solve:

44.99 ≈ |x|

This is the magnitude. To calculate the amount of work done, simply multiply by the distance she pushed the wheelbarrow:

44.99 × 25 ≈ 1124.8 J.

icang [17]

Answer:

Ratio = 3.801

Step-by-step explanation:

Given that the total assets balance at the beginning of the year was $175,000 and at the end of the year was $167,000.

Average assets for the year = $\frac{175000+167000}{2} =171000$

Sales for the year = 650000 dollars

To calculate the ratio of sales to total assets:

Required ratio = $\frac{650000}{171000} =3.801$

The coordinates of p and q are p(3,5) and q (7,1). Find the gradient of pq

Ahat [919]

Hi there!

$\large\boxed{\text{Gradient = -1}}$

We can find the slope using the slope formula:

Slope = (y2-y1)/(x2-x1)

Plug in the given coordinates:

Slope = (1 - 5)/(7 - 3)

Simplify:

Slope = -4/4

Slope = -1

Over a two week period you worked 7 1/2 hrs a day for 8 days. You earn $11.50 an hour. How much money did you earn in your paych

OleMash [197]

Answer: $\$687$

Step-by-step explanation:

Given

Working hours are $7\ \frac{1}{2}$ for 8 days

Money earned is $11.50 an hour

Total working hours

$=\dfrac{7\times 2+1}{2}\times 8=\dfrac{15}{2}\times 8\\\\=60\ hr$

Money earned

$=60\times 11.50=\$690$

After-tax deduction

$\Rightarrow 690-3=\$687$
