In y=kx , subst. -30 for x and 3 for y.  Then solve the resulting equation for k:

3 = k(-30).

Dividing both sides by -30, we get:

-3/30 = -1/10 = k

The constant of proportionality is k = -1/10.

area is measured in "square" units. ... Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared. If a square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches.

so you multiply the sides by each other.

The estimated quotient of 895 divided by 19 is what number?a. 40 b. 45 c. 55 d. 60
Ira Lisetskai [31]

Answer:

b. 45

Step-by-step explanation:

895 ÷ 19 = 47.1

47.1 rounded is 50, but since there is no 50 option, we'll just round it down to 45.

--

another way:

round 895 (900) and 19 (20)

divide:

895 ÷ 20 = 45

you'll get 45 either way :)
