Answer:

3.75

Step-by-step explanation:

\frac{x}{300} =  \frac{1.25\%}{100}

x \times 100 = 100x

300 \times 1.25 = 375

375 \div 100 = 3.75

atroni [7]

Answer:

0.79 sec

Step-by-step explanation:

Given there is a tool at the top of the building which is dropped by a worker and it follows the following equation at every instant of time .

h(t)=-16t^{2} +h_{0}

where h_{0} =10 feet

We know that this height is measured from the base of the building which means that when the tool reaches the bottom of the building it has h = 0 feet.

Let this be done at time t

h(t) = 0

-16t^{2} +10=0

t^{2} =\frac{10}{16}

t=\frac{\sqrt{10} }{4}

t = 0.79 sec

Therefore the total time taken by the tool to reach the bottom of the building is 0.79 sec.

If a wheel with a radius of 70 inches spins at a rate of 600 revolutions per minute, find the approximate linear velocity in mil
Ainat [17]
This is the concept of speed:
ω=600 rev/min=600*2π rad/min=1200 rad/min
v=rω=70*1200π =84,000 in/min
converting the above in miles per hour we get:
84000 in/min
=(84000*1.6*10^(-5)*60)
=80.64 mph

Help for number 10 please
tamaranim1 [39]

Start with

4(3^3-8) \div 2

Exponents have the highest priority, so we evaluate 3 cubed first:

4(27-8) \div 2

Next, we have to solve parenthesis first: we have 27-8 = 19, so the expression becomes

4 \times 19 \div 2

Multiplications and divisions have the same priority, so we perform them as they appear: 4 \times 19 = 76, so the expression becomes

76 \div 2 = 38
