Answer:

\text{Minutes in a year}=\frac{\text{60 minutes}}{\text{Hour}}\times\frac{24\text{ hours}}{\text{Day}}\times\frac{\text{365 days}}{\text{Year}}

Step-by-step explanation:

We are asked to find the equation that shows the number of minutes in one year.

We know that 1 hour equals 60 minutes.

1 day equals 24 hours, so number of minutes in one day would be 24\text{ hours}\times \frac{\text{60 minutes}}{\text{Hour}}=24\times 60\text{ minutes}=1440\text{ minutes}

We know that one year has 365 days, so minutes in one years would be 1140\text{ minutes}\times 365=525600\text{ minutes}

\text{Minutes in a year}=\text{Minutes in one hour}\times\text{Hours in one day}\times \text{Days in one year}

\text{Minutes in a year}=\frac{\text{60 minutes}}{\text{Hour}}\times\frac{24\text{ hours}}{\text{Day}}\times\frac{\text{365 days}}{\text{Year}}

60 minutes in an hour, 24 hours in a day, 365 days in a year. So,
60×24=1440 minutes in a day.
1440×365=525600 minutes in year. So the equation is
Minutes in an hour×Hours in a day=minutes in a day
minutes in a day×days in a year=minutes in a year

If Angela $98,760 home appreciates 3% a year will she have enough appreciation to try to sell a home for a $15,000 profit in fiv
olasank [31]

Answer:

Yes

Step-by-step explanation:

So, first, in 5 years, the home will have appreciated by 15%. (5 years times 3%). Once you find 15% of 98760, which is 658400, you have to add it on to the original price of the house. At this point, the house costs 757160 dollars. You then subtract the original price of the house from the price of the house 5 years from now. (757160-98760) and you get 658400. As you can tell, 658400>15000. Therefore, the answer is yes.

Find the degree measures of the next two positive and the previous two negative angles that are coterminal with the angle 75°.
AlladinOne [14]

9514 1404 393

Answer:

  • 435°, 795°
  • -285°, -645°

Step-by-step explanation:

Add or subtract multiples of 360° to find coterminal angles.

<u>Positive</u>

  75° +360° = 435°

  75° +2×360° = 795°

<u>Negative</u>

  75° -360° = -285°

  75° -2×360° = -645°

A trough of water is 20 meters in length and its ends are in the shape of an isosceles triangle whose width is 7 meters and heig
Vaselesa [24]

Answer:

a) Depth changing rate of change is 0.24m/min, When the water is 6 meters deep

b) The width of the top of the water is changing at a rate of 0.17m/min, When the water is 6 meters deep

Step-by-step explanation:

As we can see in the attachment part II, there are similar triangles, so we have the following relation between them \frac{3.5}{10} =\frac{a}{h}, then a=0.35h.

a) As we have that volume is V=\frac{1}{2} 2ahL=ahL, then V=(0.35h^{2})L, so we can derivate it \frac{dV}{dt}=2(0.35h)L\frac{dh}{dt} due to the chain rule, then we clean this expression for \frac{dh}{dt}=\frac{1}{0.7hL}\frac{dV}{dt} and compute with the knowns \frac{dh}{dt}=\frac{1}{0.7(6m)(20m)}2m^{3}/min=0.24m/min, is the depth changing rate of change when the water is 6 meters deep.

b) As the width of the top is 2a=0.7h, we can derivate it and obtain \frac{da}{dt}=0.7\frac{dh}{dt}  =0.7*0.24m/min=0.17m/min The width of the top of the water is changing, When the water is 6 meters deep at this rate

Hal says the volume of the sphere shown below 36 cm3. Find the correct volume, using 3.14 for pi. Round to the nearest hundredth
adelina 88 [10]

Answer:

Volume of sphere is 35.98cm^3

Step-by-step explanation:

It is given that Hal says that volume of sphere is 36cm^3

Volume of sphere is given by V=\frac{4}{3}\pi r^3

\frac{4}{3}\pi r^3=36

\pi r^3=27

r^3=8.594

r=2.048cm

Now using 3.14 in place of \pi

Now volume of sphere is

V=\frac{4}{3}\times 3.14\times 2.048^3

V=35.98cm^3

Therefore volume of sphere when we use 3.14 in place of \pi is 35.98cm^3

And the Hal likely error is he uses \pi directly for calculation of volume.
