Beverly has a bag of marbles that weighs 30 grams. she knows that each marble weighs 1.5 grams and the bag weighs 1.5 grams. which equation could she use to determine how many marbles are in the bag? select all that apply. (1.5)x + 1.5 = 30 30 – x = 2(1.5) (1.5)(30) = 1.5x 1.5 + x = 30 1.5x = 30 – 1.5

a & c

or (1.5)x + 1.5 = 30 and 1.5x = 30 – 1.5

hope this helps :)

222.76 feet

Step-by-step explanation:

This question can be solved using one of the three trigonometric ratios. The height mentioned is 90 feet and the angle of depression is 22 degrees. It can be seen that the required distance is given by x feet. This forms a right angled triangle, as it can be seen in the diagram. The perpendicular is given by 90 feet, the base is the unknown, and the angle of 22 degrees is given, as shown in the attached diagram. Therefore, the formula to be used is:

tan θ = Perpendicular/Base.

Plugging in the values give:

tan 22 degrees = 90/x.

x = 90/tan 22.

x = 222.76 feet (to the nearest hundredth).

Therefore, the building is 222.76 feet away from the sculpture!!!
