Shellac O'Lean, a freshman on your school's football team, is 6 ft tall and weighs 140 lb. Since he would rather play basketball

, he plans to grow to 7 ft 1 in., the same height as Shaquille O'Neal, his idol. If Shellac scales geometrically as he grows, how much can he expect to weigh? (O'Neal weighs 325 lb. Round your answer to the nearest whole number.)

Answer:

At 7 ft. 1 in., Shellac can expect to weigh approximately 165 lb

Step-by-step explanation:

The relationship between the heights and the weights of the freshman are presented as follows;

The weight of the freshman at 6 ft. = 140 lb

The height to which he plans to grow = 7 ft. 1 in.

Given that Shellac scales geometrically as he grows, then the height to weight ratio is constant

Let 'y' represent Shellac's weight when his height is 75 ft. 1 in., we have;

\dfrac{6 \, ft.}{140 \ lb} = \dfrac{7 \, ft. \ 1  \, in. }{y}

6 ft. = 72 in.

7 ft. 1 in. = 85 in.

Therefore, we get;

\dfrac{72 \ in.}{140 \ lb} = \dfrac{85 \ in. }{y}

y ={85 \ in. }\times \dfrac{140 \, lb}{72 \ in.} = 165.2 \overline 7 \, lbs

Shellac's expected weight given to the nearest whole number when his height is 7 ft. 1 in. ≈ 165 lb.

Find the measure of an angle between 0 and 360 that is coterminal with -120
AURORKA [14]

Answer:to find the equivalent positive angle of a negative angle, just add 360 to it until it becomes positive and is between 0 and 360 degrees. -110 + 360 = 250. 250 degree angle and -110 degree angle are coterminal


Step-by-step explanation:to find the equivalent positive angle of a negative angle, just add 360 to it until it becomes positive and is between 0 and 360 degrees. -110 + 360 = 250. 250 degree angle and -110 degree angle are coterminal

Holly has $125 she spends $35 on gas for her car which model represents how much money holly has left idk if the answer is right
inn [45]

Answer:

The second one would be the answer.

Step-by-step explanation:

If you look at the model, it shows it on 125 going down to 90.

If she has $125 and she spends $35 on gas, you would subtract that from how much money she has.

125 - 35 = 90.

Feel free to let me know if you need more help. :)
