Answer:

B and C

Step-by-step explanation:

We can just solve each to find which expressions are equal to 1.5.

A) 0.15 × 100 = 15

B) 15.0 ÷ 10 = 1.5

C) 0.15 × 10 = 1.5

D) 0.15 ÷ 10 = 0.015

E) 1.5 ÷ 100 = 0.015

From our results, we see that B and C are the only answers that equal 1.5.

Jacie can swim 3/4 of a mile in 3/8 of an hour.how far can she swim in one hour?

Vladimir [108]

Answer:

2 miles

Step-by-step explanation:

convert 3/4 into 6/8. With this you have a ratio of 6/8 miles to 3/8 hours. Meaning 2/8 mile is equal to 1/8 of an hour. With this you can find that Jacie can swim 2 miles in a hour

Answer:

v = 8.49 m/s rounded off to 3 significant figures

Step-by-step explanation

Using Energy Conservation

U = Tk + Vp (Sum of kinetic Tk Energy and gravitational potential Vp Energy)

At height = 3.67 m, the hammer was still or the velocity was negligible; hence, vi = 0 m/s.
Ui = 0 + mgh
At ground all potential energy is converted to kinetic; hence, Uf = $\frac{1}{2}$ mv².
Since total energy of the system remains constant we equate Ui to Uf.
Ui = Uf
mgh = $\frac{1}{2}$ mv²
After cancelling out masses and making v the subject of the formula we get:

v = $\sqrt[2]{2gh}$ = $\sqrt[2]{2*9.81*3.67}$ = 8.49 m/s rounded off to 3 significant figures
