Which equation could be used to find the area in square centimeters of a circle with a radius of 26 centimeters?
A- A= 13 X
B- Α =πX 132
С- A= 26 X pie
D- Α =πX 262

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:

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:

you get 27

Step-by-step explanation:

subtract 63 from both sides

then divide by 11

Answer:

answer: 27

Step-by-step explanation:

To find this you just have to do 11 multiplied by x + 63 so 11 × 27 = 297 and 297 + 63 = 360 so x = 27 Hope that helps!

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.

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:

708meters

Step-by-step explanation:

Given data

Lenght = 274meters

Width= 80 meters

The expression for the perimeter is

P= 2L+2W

substitute

P= 2*274+ 2*80

P= 548+160

P= 708 meters

Hence the perimeter of the block is 708meters

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:

Area of a Circle = πr²

R=Diameter/2

=21mm

=π(21)²

=1385.44mm²

To the nearest whole number

= 1385mm²

The answer is in mm². It may differ if the given answer is in m². You can get this by converting your radius to meters. This is done by dividing 21mm by 1000.
