What is the area of the circle?
a) 18.84 square kilometers
b) 113.04 square kilometers
c) 37.68 square kilometers
d) 84 square kilometers

Answer:

[tex]y=\frac{1}{2}x-6[/tex]

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Determine the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (2,-5) and (8,-2)

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\=\frac{-2-(-5)}{8-2}\\=\frac{-2+5}{8-2}\\=\frac{3}{6}\\=\frac{1}{2}[/tex]

Therefore, the slope of the line is [tex]\frac{1}{2}[/tex]. Plug this into [tex]y=mx+b[/tex]:

[tex]y=\frac{1}{2}x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=\frac{1}{2}x+b[/tex]

Plug in one of the given points and solve for b

[tex]-5=\frac{1}{2}(2)+b\\-5=1+b[/tex]

Subtract 1 from both sides to isolate b

[tex]-5-1=1+b-1\\-6=b[/tex]

Therefore, the y-intercept of the line is -6. Plug this back into [tex]y=\frac{1}{2}x+b[/tex]:

[tex]y=\frac{1}{2}x+(-6)\\y=\frac{1}{2}x-6[/tex]

I hope this helps!

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

She wont think it is perfect

Step-by-step explanation:

The ratio of Ari's perfect ice cream is

333 caramel : 555 scoops

Freeze zone ratio is

666:888

Not proportional because you multiply 333 x 2 to get 666, but when you multiply 555 x 2 you wont get 888.

Answer:

A

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:

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.

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.

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.

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]
