Answer: Hence, Options (1), (2), (3), (6), (7) are correct.

Step-by-step explanation:

Since we have given the figure:

According to figure, we get that

Angle 1, Angle 2, Angle 4 are exterior angles.

Angles 6 and 8 are remote interior angles to the exterior angle 1.

Because ∠6+∠8 = ∠1

Angles 6 and 7 are remote interior angles to the exterior angle 2.

Because ∠6+∠7 = ∠2

Hence, Options (1), (2), (3), (6), (7) are correct.

It takes 60 minutes to make 2000 copies on an old copy machine. The newer copier works with the old copier to create 2000 sheets
Cerrena [4.2K]

The new copier can create 2000 copies in 20 minutes.

Step-by-step explanation:

Given,

It takes 60 minutes to make 2000 copies by old printer and 15 minutes to made x number of copies, therefore, using proportion

60:2000::15:x

Product of mean = Product of extreme

2000*15=60*x\\30000=60x\\60x=30000

Dividing both sides by 60

\frac{60x}{60}=\frac{30000}{60}\\x=500

As the new copier is working with old copier, therefore,

Copies made by new printer = 2000 - 500 = 1500

New copier can make 1500 copies in 15 minutes and 2000 copies in x minutes, using proportion

1500:15::2000:x\\1500*x=15*2000\\1500x=30000

Dividing both sides by 1500;

\frac{1500x}{1500}=\frac{30000}{1500}\\x=20

The new copier can create 2000 copies in 20 minutes.

how many miles should a person who drives for 48 minutes expect to travel? 32 miles 42 miles 48 miles 54 miles
ra1l [238]
'expect' to travel? 48 ... assuming he's driving at a normal (average) highway speed of 60 MPH.
But, of course, what is key here is that we cannot be certain because the response will change depending on his speed. (...and the problem as written doesn't provide that.)
