We know how many miles he drove and the speed that he drove. We do not know how long i took him to drive that distance.

To find the time it took, divide the distance by his speed:

325 miles / 65mph = 5 hours.

Choose the possible descriptions of cross sections formed by the intersection of a plane and a rectangular prism.
xxMikexx [17]

Answer:

-rectangle  

-triangle

-line segment  

-point  

Step-by-step explanation:

A rectangle is formed when the intercepting plane is parallel to two of the faces of the prism

A triangle is formed when the plane cuts the prism near only one vertex, it is not parallel to the faces and 3 edges are cutted

A line segment  is formed when the plane "touches" only one edge of the prism

A point  is formed when the plane "touches" only one vertex of the prism

If APOR is an equilateral triangle, PQ = 18x + 1, QR = 24x – 17, and PR = 15x + 10, find x and
sveticcg [70]

Answer:

The value of x is 3 and measure of each side is 55.

Step-by-step explanation:

Consider the provided information.

If ΔPOR is an equilateral triangle,

PQ = 18x + 1, QR = 24x – 17, and PR = 15x + 10,

A triangle is said to be equilateral if all the sides are equal.

Therefore, PQ = QR = PR

PQ = QR \\18x + 1,=24x-17\\6x=18\\x=3

Therefore, the value of x is 3.

PQ = 18x + 1

PQ = 18(3) + 1

PQ = 55

As we know PQ = QR = PR

Thus QR = 55 and PR = 55

The value of x is 3 and measure of each side is 55.

Solve R=r1+r2 for r2
Sphinxa [80]
R=r1+r2
simple
all you have to do is leave r2 by itself...
(r2=??)
by doing so you need to subtract r1 on both sides
R-r1=r2
and by doing so you leave r2 by itself
r2=R-r1

Figure ABCD is rotated clockwise about the origin through 90°. Identify the coordinates for the given figure after 90° rotation
nydimaria [60]

Answer:

D[3, 3], C[1, 4], B[0, 1], A[4, -1]

Step-by-step explanation:

Whenever you are doing a 90° clockwise rotation ABOUT THE ORIGIN, it is in the form of [<em>y</em><em>,</em><em> </em><em>-</em><em>x</em>], meaning you take the <em>y</em><em> </em>and make it your <em>x</em><em>,</em><em> </em>then take your original <em>x</em><em> </em>and put its OPPOSITE.

90° counterclockwise rotation → [<em>-y, x</em>]

90° clockwise rotation → [<em>y, -x</em>]

I hope this helps, and as always, I am joyous to assist anyone at any time.
