Answer:

He drove 111 miles

If we were given the distance Lan drove last weekend instead off how much gas he used then we would have to find the amount of gas used by lan.

Step-by-step explanation:

Ian's car can go 185 miles on 5 gallons of gas

On 5 gallons of gas lan's car can go 185 miles

Therefore in gallon of gas lan 's car can go

185/5 = 37

So, for 3 gallons of gas lan's car can go

3 × 37 = 111

for 3 gallons of gas lan's car can go 111 miles

If we were given the distance Lan drove last weekend instead off how much gas he used then we would have to find the amount of gas used by lan.

Find the slope, distance and midpoint between

Dovator [93]

Answer:

Slope- 4

Distance- 12.4

Midpoint- (6,8)

Step-by-step explanation:

Slope- $\frac{y2-y1}{x2-x1}$

$\frac{2-14}{4-7} =\frac{-12}{-3}=4$

Distance- $d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}$

$d = \sqrt{(4 - 7)^2 + (2-14)^2}$

$d = \sqrt{-3^2 + -12^2}$ $d = \sqrt{144+9}=\sqrt{153}$

$\sqrt{153} = 12.4$

Midpoint- $\frac{x1+x2}{2} ,\frac{y1+y2}{2}$

$\frac{7+4}{2} =\frac{12}{2} = 6=x$

$\frac{14+2}{2} = \frac{16}{2} = 8 = y$

(6,8)

A circle with area \blue{9\pi}9πstart color #6495ed, 9, pi, end color #6495ed has a sector with a central angle of \purple{60^\c

Liono4ka [1.6K]

Answer:

The area of the sector is 3pi/2

Step-by-step explanation:

A sector is that part of a circle bounded by 2 radii and an arc

The circle has an area of 9 pi with a central angle of 60 degrees.

Now the area of the sector is pretty much straight forward to calculate. Since it is a circle, the total angle we have is 360.

Now the sector subtends an angle of 60 degrees at the centre. What this means is that the sector is exactly 1/6 of the circle. meaning that cutting the circle into 6 slices will give the sector.

Thus, the area of the sector is one-sixth the area of the circle.

The area of the sector is thus 1/6 * 9pi = 9pi/6 = 3pi/2 or 3/2 pi
