The greatest common factor of 45 and 72 is 9 because the factors of 45 is 1, 2, 3, 5, 9, 15, 45. And the factors of 72 is 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72. The greatest commen factor is the factor that is the greatest and is the same in both of the sets of factors. 1 is a factor between them but it is not the greatest, not 2 or 3, but it is 9 because it is the greatest and each set has 9. Thank you for asking, have a great afternoon :)

Answer: $e=-50|t-40|+2000$

The cable car’s elevation will be 750 feet after 15 minutes or 65 minutes.

Step-by-step explanation:

Given: A cable car begins its trip by moving up a hill. As it moves up, it gains elevation at a constant rate of 50 feet/minute until it reaches the peak at 2,000 feet.

Then, total time taken to reach the peak = (Distance) ÷ (speed)

= (2,000 feet) ÷ ( 50 feet/minute)

= 40 minutes

Then, as the car moves down to the hill’s base, its elevation drops at the same rate.

The equation that models the cable car’s elevation, e, after t minutes is

e= (constant rate)|t- time to reach peak |+ Peak's height

$e=-50|t-40|+2000$

When the cable car’s elevation will be 750 feet after minutes, then we have

$750=-50|t-40|+2000\\\\\Rightarrow\ -50|t-40|=750-2000\\\\\Rightarrow\ -50|t-40|=1250\\\\\Rightarrow|t-40|=-\dfrac{1250}{50}\\\\\Rightarrow|t-40|=-25\\\\\Rightarrow t-40=-25\text{ or }t-40=25\\\\\Rightarrow t=-25+40\text{ or }t=25+40\\\\\Rightarrow t=15\text{ or }t=65$

Time cannot be negative, so the cable car’s elevation will be 750 feet after 15 minutes or 65 minutes.

The triangles are similar. The area of the larger triangle 603cm2. what is the area of the smaller triangle?

tekilochka [14]

The smaller triangle is scaled by a factor of (18 cm)/(54 cm) = 1/3 of the larger triangle. The ratio of areas is the square of that scale factor.

small triangle area = (1/3)^2 × large triangle area

... = (1/9) × 603 cm^2

... = 67 cm^2

The appropriate choice is

... C. 67 cm^2
