1 km = 1000 meters.

Find total meters: 80 km x 1000 meters per km = 80,000 meters.

Divide total meters by the given speed:

80,000 meters / 180 m/s = 444.44 seconds.

1 minute = 60 seconds

444.44. Seconds / 60 seconds per minute = 7.41 minutes = 7 minutes 24.42 seconds

Total time = 7 minutes 24.42 seconds

Round as needed.

Answer:

146

Step-by-step explanation:

angle AB is an inscribed angle and arc AB is it's intercepted arc

An inscribed angle is equal to half the measure of its intercepted arc

Which means that an intercepted arc is equal to two times the measure of its corresponding inscribed angle

Thus, arc ab = 2(73)

2 * 73 = 146

hence, arc AB = 146

Answer:

mAB = 146°

Step-by-step explanation:

We can notice that the angle given is an inscribed angle and an inscribed angle is 1/2 the arc it intercepts. We can set up an equation to model the situation:

73° = 1/2(mAB)

mAB = 146°

Answer:

domain: {-2, -1, 0, 1, 2}

range: {0, 2, -4, -8}

Step-by-step explanation:

The domain is a set of all the x-values in the graph. This is made up of:

{-2, -1, 0, 1, 2}

The range is made up of all the y-values(no repeats):

{0, 2, -4, -8}

Answer:

the answer is B

Step-by-step explanation:

because it is in the form ax^2+bx+c

Answer:

x=44 and y=21

Step-by-step explanation:

The large one is x

The small one is y

According to given conditions,

x+y=65[Sum of two number is 65]—Equation(1)

x-23=y [Smaller number is less than 23 than larger]——Equation (2)

From equation (2) we can write,

x-y=23——-Equation(3)

Now adding equation (1) and (3) we get,

x+y+x-y=65+23

=>2x=88

=>2x/2=88/2 [Both sides are divided by 2]

=>x=44

Now putting the values in equation (2) we get,

44–23=y

=>y=21

Large, x=44 and Small, y=21

Answer:[tex]34,650\ in^3[/tex]

Step-by-step explanation:

Given

The height of the aquarium is [tex]h=25\ inches[/tex]

The radius of the aquarium is [tex]r=21\ inches[/tex]

Assuming aquarium to be in the shape of a cylinder

So, its volume is [tex]V=\pi r^2h[/tex]

Insert the values

[tex]\Rightarrow V=\pi \times 21^2\times 25\\\Rightarrow V=34,650\ in^3[/tex]

Thus the volume of the aquarium is [tex]34,650\ in^3[/tex].

Answer:

5.266 secs

Step-by-step explanation:

Lets assume ; p(t) = t^-3 + 2^2 + ( 3/2 ) is the particle position along x-axis

time interval [ 0, 4 ]

Average velocity = Displacement / time

                            = p( b ) - p( a ) /  b - a -------- ( 1 )

where a = 0 , b = 4 ( time intervals )

Back to equation 1

Average velocity = [ ( 4^-3 + 4 + (3/2) ) - ( 0 +  4 + (3/2) ) ] / 4

                             = 3.9 * 10^-3 ----- ( 2 )

Instantaneous velocity = d/dx p(t)

                                      = - 3/t^4  ------ ( 3 )

To determine the time that the instanteous velocity = average velocity

equate equations (2) and (3)

3.9*10^-3 = - 3 / t^4

t^4 = - 3 / ( 3.9 * 10^-3 ) = - 769.231

hence t = [tex]\sqrt[4]{- 769.231 }[/tex] = 5.266 secs

we ignore the negative sign because time can not be in the negative

Answer: 378

Step-by-step explanation:

You would get this answer because if x = 7 then you multiply and get 21 because 3 x 7 = 21 then you do what’s in the parentheses and get 18 then multiply 21 x 18 then you get 378

Answer:

15%

Step-by-step explanation:

Find the percent of profit by dividing 45 by 300:

45/300

= 0.15

So, the percent profit was 15%

You receive 45\$ profit from a car wash after 300\$ in sales.

so,

percentage of profit

Answer:

9 years

Step-by-step explanation:

Let

Lifespan of rabbits = x

Lifespan of hamster = x - 4

Lifespan of raccoon = 2(x - 4)

Total lifespan of animals = 24

Total = rabbits + hamster + raccoon

24 = x + (x - 4) + 2(x - 4)

24 = x + x - 4 + 2x - 8

24 = 4x - 12

24 + 12 = 4x

36 = 4x

x = 36/4

x = 9 years

longevity for the rabbit = 9 years

Lifespan of rabbits = x = 9

Lifespan of hamster = x - 4

= 9 - 4

= 5

Lifespan of raccoon = 2(x - 4)

= 2(9 - 4)

= 2(5)

= 10

Total lifespan of animals = 24

Answer:

36 1/4 in³

Step-by-step explanation:

v = 3 5/8 * 2 1/2 * 4

Convert to improper fractions

v = 29/8 * 5/2 * 4/1

Cancel

v = 29/2 * 5/2 * 1/1

Multiply

v = 145/4

Reduce

v = 36 1/4 in³

Answer:

175 degrees

Step-by-step explanation:

So we see that this is a supplementary angle, which means it is equal to 180/ So set the equations up and solve for x:

[tex]180=29+(x-5)\\180=24+x\\156=x\\[/tex]

Then, plug 156 back into the equation:

[tex]180-5\\175[/tex]

Therefore, your answer is 175 degrees

Answer:

1/10 = 0.1 = (0.1×100) %= 10%

1/5 = 0.2 = (0.2×100)% = 20%

3/4 = 0.75 = (0.75×100)% = 75%

3/10 = 0.3 = (0.3×100)% = 30%

1/4 = 0.25 = (0.25×100)% = 25%

Hope it helps

Answer:

1/2 = 0.5 50%

1/10 = 0.1 10%

1/5 = 0.2 20%

3/4 = 0.75 75%

3/10 = 0.3 30%

1/4 = 0.25 25%
