Answer:

Divide the figure above into a cylinder and a dome

+) the volume of the dome is

[tex]v1 = \frac{1}{12} \pi6 {}^{3} = 18\pi[/tex]

the surface area is

[tex]s1 = \pi3 {}^{2} = 9\pi[/tex]

+) the volume of the cylinder is

[tex]v2 = \pi.3 {}^{2} .13 = 117\pi[/tex]

the surface area is

[tex]s2 = 2\pi.3.13 + 2\pi.3 {}^{2} = 96\pi[/tex]

so the volume of this figure is

[tex]v = v1 + v2 = 18\pi + 117\pi = 135\pi[/tex]

the surface area of this figure is

[tex]s = 9\pi + 96\pi = 105\pi[/tex]

Answer:

c

Step-by-step explanation:  

Answer:

In order to find the distance traveled in one minute, you have to divide the distance he can ride his bike in an hour by the number of minutes in a hour. 6/60= .1 mile per minute. If he rides his bike for five minutes, then you would multiply the number of minutes biked by the distance traveled in a minute. .1*5=.5 mile, or [tex]\frac{1}{2}[/tex] mile.

Step-by-step explanation:

The cyclist will travel 4 miles in 20 minutes.

Speed is the time rate at which an object is moving along a path,

To find the speed per minute, we can use the fact that there are 60 minutes in an hour. Therefore:

12 miles per hour = 12/60 miles per minute = 0.2 miles per minute

So the cyclist's speed is 0.2 miles per minute.

To find how many miles the cyclist will travel in 20 minutes, we can use the formula:

distance = rate x time

Plugging in the given values, we get:

distance = 0.2 miles per minute x 20 minutes

distance = 4 miles

Therefore, the cyclist will travel 4 miles in 20 minutes.

Answer:

45°

Step-by-step explanation:

-45° would be 360°-45°=315°

Since 315° is in Quadrant IV, then its reference angle is 360°-315°=45°

So really, -45° is just 45° clockwise which is also our reference angle.

[tex]456+788-129\cdot \:9\\\\129\cdot \:9=1161\\\\456+788=1244\\\\1244-1161=83\\\\=83[/tex]

Answer:

x = 30 and y = 50

Step-by-step explanation:

Given that,

The cost of 4 shirts and 1 pair of pants is $170 and the cost of 5 shirts and 2 pair of pants is $250.

Let the cost of 1 shirt is x and that of 1 pant is y.

So,

4x+y=170 .....(1)

5x+2y = 250 .....(2)

Multiply equation (1) by 2.

8x+2y=340 .......(3)

Subtract equation (2) from (3).

8x+2y-(5x+2y)=340-250

3x = 90

x = 30

Put the value of x in equation (1).

4(30)+y=170

120+y=170

y = 170-120

y = 50

Hence, the value of x is 30 and that of y is 50.

Answer:

3.14 cm

Step-by-step explanation:

From the question,

Applying

s = πdФ/360................... Equation 1

Where s = length of arc AB, d = diameter of the circle, Ф = angle at the center of the circle, π = pie

From the question,

Given: d = 8 cm, Ф = π/4 rad = 45°

Constant: π = 22/7

Substitute these values into equation 1

s = (22/7)(8)(45)/360

s = 3.14 cm.

Hence the lenght of arc AB = 3.14 cm

Answer: 76%

The fraction of questions Emerson has completed is 19/25. To convert this to a percentage, we want to write this as something divided by 100. To do so, multiply the numerator and denominator by 4, to get the fraction 76/100. Therefore, Emerson has completed 76% of the homework questions.

If you have access to a calculator, a more efficient way to solve such a question would be to convert 19/25 to a decimal (it is equal to 0.76), and multiply by 100 to get 76%.

Step-by-step explanation:

The equation of the parallel line is:

y = -2x + k

such that k ≠ 9.

We know that two linear equations are parallel if they have the same slope and different y-intercept.

Then, a parallel line to:

y = -2x + 9

Would be something of the form:

y = -2x + k

such that k ≠ 9.

Then, for example:

y = -2x + 3

Is parallel to the given line.
