7 0

Answer:

1/2

Step-by-step explanation:

Or, 8(x-3)+7= 2x(4-17)

Or, 8x-24+7=2x(-13)

Or, 8x-17= -26x

Or, 34x=17

x=1/2

Justin is on a road trip. Over the past two days, he’s driven a total distance of 504 miles at an average speed of 56 miles/hour
irakobra [83]
Recall d  = rt, distance = rate * time.

now, he has a speed rate of 56 mph for a distance of 504

\bf d=rt\implies 504=56t\implies \cfrac{504}{56}=t\implies \stackrel{hours}{9}=t

so, at that speed the whole driving time is 9 hours then.  Ok, he drove 2 hours today, that means he drove 7 yesterday, 9 - 2.

how many miles is it for 7 hours at 56mph?  d = rt ---> d = 56 * 7

that many miles he drove yesterday.

2.

We have a transversal across parallel lines so we get the usual array of congruent and supplementary angles.  We just have to figure out which is which, and the diagram, even though not to scale, makes it pretty obvious.

Angle x isn't the same as the 40° angle so it must be its supplement.

Answer: C 140°

3.

r=1.2, h=2.9, V = (1/3) πr²h

Nothing hard here, we just plug in the numbers,

V = (1/3) π (1.2)² (2.9) ≈ 4.37310

Answer: B. 4.4 cubic inches

4.

Dilation by .5 makes a similar triangle, and reflection is an isomorphism (i.e. it doesn't change the size or shape) so the answer is

Answer: B similar not congruent

5.

The corresponding interior and exterior angles of a triangle form a linear pair, so supplementary angles. x=180-110 = 70°

Answer: A 70°

An arc on a circle measures 250 degrees. Within range which range is the radian measure of the central angle?
blondinia [14]

If the arc measures 250 degrees then the range of the central angle lies from π to 1.39π.

Given that the arc of a circle measures 250 degrees.

We are required to find the range of the central angle.

Range of a variable exhibits the lower value and highest value in which the value of particular variable exists. It can be find of a function.

We have 250 degrees which belongs to the third quadrant.

If 2π=360

x=250

x=250*2π/360

=1.39 π radians

Then the radian measure of the central angle is 1.39π radians.

Hence if the arc measures 250 degrees then the range of the central angle lies from π to 1.39π.
