JulsSmile [24]
There are 60 students. The winner got 70% of the 60 students votes. Let's work this one out to get the answer.

First, you need to figure out what 70% of 60 is, by using this equation.
60 x .70 = 42.
Now that you know the answer is 42, you now know that 70 percent of 60 is 42.

So, the class president got 42 winning votes!






Hope I could help!

Find the missing side
dybincka [34]

Answer:

7) 8.94

8) 6.71

Step-by-step explanation:

for both questions, use pythagorean theorem

a^{2} + b^{2} = c^{2}

<u>Question 7:</u>

4^{2} + 8^{2} = c^{2}

16 + 64 = c^{2}

80 =  c^{2}

\sqrt{80} = \sqrt{c^{2}}

c = 8.94

<u>Question 8:</u>

6^{2} + 3^{2} = c^{2}

36 + 9 = c^{2}

45 = c^{2}

\sqrt{45} = \sqrt{c^{2} }

c = 6.71

3. In order to enter the state fair, there is
Anastasy [175]

Answer:

C = 8 + 3x

The rate of change in the above equation is 3 dollars per game and it interpret the cost per game.

The initial value in the above equation is 8 dollars, which interpret the entry fee that every one person has to pay to enter the fair.

Step-by-step explanation:

Let the admission cost of the fair is $x and each game is $3.

Now, Steven went to the state fair, played  4 games and spent a total of $20 on  admission and games.

So, we can write 20 = x + 4 × 3 {As the relation is linear}

⇒ x = $8

Therefore, the admission cost in the fair is $8.

Therefore, the equation that models the situation is  

C = 8 + 3x ............ (1)

Where C is the total cost and x is the number of games played.

So, the rate of change in equation (1) is 3 dollars per game and it interprets the cost per game.

Again, the initial value in equation (1) is 8 dollars, which interprets the entry fee that each person has to pay to enter the fair. (Answer)
