Answer: The fewest number of volunteers needed to have enough judges for all of the projects is 2.

Step-by-step explanation:

Number of science teachers = 133

Number of science fair projects viewed by each judge = 5

Let the number of judge be n

Since number of volunteers must be multiple of 5 .

According to question,

5n=135+\text{number of volunteers}\\\\\text{ where, n is a natural number and number of volunteer must be integer}

So, Possibility for number of volunteers must be 2 to make it divisible by 5.

5n=133+2\\\\5n=135\\\\n=\frac{135}{5}\\\\n=27

Hence, the fewest number of volunteers needed to have enough judges for all of the projects is 2.

Sasha is cutting a cake into 42 equal-sized pieces. If 14 people want cake, then they can each have 3 slices. And if 21 people w
kupik [55]

Answer:

k = 42

the constant of proportionality in this inverse variation is 42.

Step-by-step explanation:

Let x represent the number of people that want cake

And y the number of slices each can have;

Since x is inversely proportional to y;

x = k/y .....1

Where k is the proportionality constant;

To solve for k, we will substitute any of the case scenario given into equation 1.

If 14 people want cake, then they can each have 3 slices;

x = 14 , y = 3

substituting;

14 = k/3

k = 14 × 3 = 42

k = 42

the constant of proportionality in this inverse variation is 42.

Therefore,

x = 42/y

Leila is buying a dinosaur model. The price of the model is xxx dollars, and she also has to pay a 7\%7%7, percent tax.
svlad2 [7]

Answer:

Leila is buying a dinosaur model. The price of the model is xxx dollars, and she also has to pay a 7\%7%7, percent tax.

Which of the following expressions could represent how much Leila pays in total for the model?

Step-by-step explanation:

The original price of the dinosaur model is "x" dollars

On top of that, the sales tax is 7% of the original price

Hence,

The total price would be the original amount PLUS the taxed amount

Original Amount = x

Taxed Amount = 7% of x

That is, 7% in decimal multiplied with "x".

7/100 = 0.07

0.07 * x = 0.07x

Total amount = x + 0.07x = 1.07x

The expression for total amount is 1.07x

Are these correct? ILL MARK YOU BRAINLIEST
Oxana [17]

Answer:

Yes

Step-by-step explanation:

1) Cos 300 = Cos (360 - 60) = Cos 60    {Cos 360 - theta = Cos theta}

                                              = 1/2

Sin 300 = Sin (360 - 60) = -Sin 60 = \frac{-\sqrt{3}}{2}

3) 3π/4 = 3*180/4 = 135

Cos 135 = Cos (90 + 45) = -Cos 45 = \frac{-\sqrt{2}}{2}

Sin 135 = Sin (90 + 45) = Sin 45 = \frac{\sqrt{2}}{2}
