1 answer:

4 0

The total distance is given as 18 miles
she traveled at 45 miles per hour for 20 minutes

20 minutes = 20 / 60 = 1/3 of an hour

45 miles per hour x 1/3 of an hour = 15 miles driven

18 total miles - 15 miles driven = 3 miles left

she then drove at 20 miles per hour

20 miles per hour / 60 minutes per hour = 1/3 mile per minute = 1 mile every 3 minutes

3 miles x 3 minutes = 9 minutes to drive the final 3 miles

20 minutes + 9 minutes = 29 total minutes to drive to work

she left at 7:15

7:15 + 20 minutes = 7:35 am she arrived at work

Triangle PQR has coordinates P(–8, 3), Q(–8, 6), and R(–3, 6). If the triangle is translated by using the rule (x, y) right-arro

omeli [17]

Answer:

Step-by-step explanation:

The rule (x, y ) → (x + 4, y - 6 )

means add 4 to the original x- coordinate and subtract 6 from the original y- coordinate, thus

P(- 8, 3 ) → P'(- 8 + 4, 3 - 6 ) → P'(- 4, - 3 )

Q(- 8, 6 ) → Q'(- 8 + 4, 6 - 6 ) → Q'(- 4, 0 )

R(- 3, 6 ) → R'(- 3 + 4, 6 - 6 ) → R'(1, 0 )

Pleaseeeeee help <br><br> The measure of angle is (5pi)/6 The equivalent measurement in degrees is

Archy [21]

Answer:

To convert from degree to radian we multiply the angle by

π/180

To convert from radian to degree we multiply the angle by

180/π

5π/6,

Multiply by

180/π

5π/6 × 180/π = 5 × 30 = 150 degrees.

⇒5π/6 radian =150 degree.

Volume of a cone = r²h,

inessss [21]

Answer:

7.5 m 457.5 $\pi$ $m^{2}$

Step-by-step explanation:

First, visualize the original cone and the smaller cone as overlapping similar triangles. The scale factor of the original cone to the smaller cone is 50:40, so if the smaller cone has a radius of 6 m, then the radius of the original cone would be 7.5 m.

The volume of the frustum is the volume of the original cone minus the volume of the smaller cone. The formula for the volume of a cone is V = $\frac{1}{3} \pi r^{2}h$ .
