4. This is simple the answer would be C. 60 because if you divide 9 by 1.50 you would get 6, so then you would need to multiply 6 by the number of erasers which is 10. So, 6 times 10 is 60.

5. This answer would be A. 1700 because (17 x 4) is 68 and 68 times 25 is 1700.

Hoped this helped!

What is the benefit of dividing out greatest common factors (GCFs) before multiplying?
Nina [5.8K]
Lets get an example, for this example lets use 24/30 x 30/60
Without dividing out GCFs  you would get 24x12 over 30 x 60 which is 288/1800
With dividing out GCFs you get 2/1 x 5/1 Which is 7 :)

A lifeguard is in a look out chair and sees a person in distress. The eye level of the lifeguard is 15 feet above the ground. Th
faltersainse [42]

Answer:

Horizontal distance between lifeguard and the person is 22 feet.

Step-by-step explanation:

Given: A lifeguard sees a person in distress.The eye level of the lifeguard is 15 feet above the ground. Angle of depression is 34°.

To find: Horizontal distance between lifeguard and the person.

Solution : If we draw a triangle then tan∅ = \frac{height}{base}

               Here base is the horizontal distance.

               Now we put the values in the formula.

               tan 34° = \frac{15}{base}

              Or Base = \frac{15}{tan34}

                             = \frac{15}{0.675} = 22.22 feet

So the answer is 22 feet.

If the center of a circle is<br> (-5,8) and a point on the circle is (-5, -4) What is the radius?
Maslowich

Answer:

The radius is 12.

Step-by-step explanation:

You're given the center and a point on the circle. The point and the center both have an x-coordinate of -5, so there is no horizontal distance between them. The distance is only in the vertical direction. The distance from 8 to -4 is 12. Since this is the distance from the center to a point on the circle, this equals the radius.
