Answer: Collins has 1/2 of an apple left.

Step-by-step explanation:

Collins shared 4/8 of an apple with two siblings, and these pieces add up to 1/2, so 1 - 1/2 = 1/2 apples.

Andrew is paid $4 per hour for the first 30 hours he works each week. he makes $5 per hour for each hour he works over 30 hours

Ksivusya [100]

W = 120 + 5(h - 30).

So, if he works 35 hours, he will earn:

120 + 5(35 - 30) = 120 + 5(5) = 120 + 25 = $145.

If he works 42 hours, he will earn:

120 + 5(42 - 30) = 120 + 5(12) = 120 + 60 = $180.

You want to calculate the displacement of an object thrown over a bridge. Using -10 m/s^2 for acceleration due to gravity, what

MrRissso [65]

Answer

The total displacement of the object is 320 m

Solution-

From the formulas of mechanics,

$s=ut+\frac{1}{2}at^{2}$

Where,

s = displacement

u = initial velocity = 0 ( ∵ As the body was in rest in the beginning )

t = time taken = 8 s

a = acceleration = -10 m/s² ( ∵ -ve is because of the downward motion)

Putting all the values,

$s= 0 \times 8 + \frac{1}{2}(-10)8^{2} = -320 \ m$ ( ∵ -ve displacement means it is in downwards)

Acone has a height of 7 ft and a radius of 4 ft. Which equation can find the volume of the cone?

Marina86 [1]

Answer:

Volume of the cone = $117.06\,feet^3$

Step-by-step explanation:

Height of the cone = $7\,feet$

Radius of the cone = $4\,feet$

Volume of a cone is:

$\pi \times r^2\times \dfrac{h}{3}$

As, $\pi =\dfrac{22}{7} =3.14$

Volume is:

$=3.14\times(4\times 4)\times \dfrac{7}{3}\\\\ =3.14\times 16 \times 2.33\\\\=3.14\times 37.28\\\\=117.06\,feet^3$

The volume of the cone is: $117.06\,feet^3$
