Answer:

(D) y=\frac{18}{6}x

Step-by-step explanation:

We will be able to know if an equation has a constant of proportionality of 3 if the constant which is being multiplied by x is equal to 3.

\frac{8}{5} =1.6 so no for A.

\frac{1}{3} = 0.\overline{33} so no for B too.

\frac{1}{4} = 0.25 so no for C as well.

\frac{18}{6} = 3, so D works.

Hope this helped!

Evaluate each expression when a = -4 and b = 3<br><br>1.) ab<br>2.) 2a + 3b <br>2.) 2(a - b)​
Svet_ta [14]

1) -12

ab is a times b. We plug in the numbers (-4)*(3) which equals -12.

2) 1

We plug in -4 for a, and 3 for b into the equation.

We get 2(-4) + 3(3)

2*-4 is -8. 3*3 is 9. We add them both, and -8+9 equals 1.

3) -14

We plug in -4 for a, and 3 for b into the equation.

2(-4-3)

-4-3 is -7. -7*2 equals -14.

Find the area of the shaded figure.
olasank [31]

Answer:

8500 ft²

Step-by-step explanation:

First we need to find the area of the non shaded region within this shaded region. To find the area of this non shaded rectangle, use the formula base×height.

20×100=2000 ft².

Now we need to find the height and width of the shaded region which is,

25+25+20=70 Height

25+25+100=150 Width

mutiply these numbers 150×70=10500 ft²

Now we just need to subtract that inside area.

10500-2000=8500 ft²

Stacy uses a spinner with six equal sections numbered 2, 2, 3, 4, 5, and 6 to play a game. Stacy spins the pointer 120 times and
Alex17521 [72]

Answer:

The solution is given below;

Step-by-step explanation:

The computation is shown below:

There is six equal sections are numbered i.e. 2, 2, 3, 4, 5, and 6.

And, Number of Outcome of 2 on the Spinner is 2

Also, total Number of Sections is 6

As the winning spin is a 2

So, The theoretical probability of winning

= 2 ÷6 × 100

= 33.33%

Now

There is a total no of trials be 120

And, the number of outcome of 2 be 30

So, the experimental probability is 30 ÷ 120 = 1 ÷ 4 × 100 = 25%

As 33.3%>25%, this represent that the theoretical probability of winning would be greater.
