Answer:

C ; 35 Seventh Graders

Step-by-step explanation:

The ratio is 40 to 7 and 40 times 5 is 200. So all you have to do is 5 times 7 to get 35 seventh- graders likely attend after-school programs!

Good luck!

The probability of a football team winning a game is three fifths. If they play 45 games in a season, how many games would you e

Charra [1.4K]

Answer:

27 games

Step-by-step explanation:

The probability of them winning is 3 out of 5 games.

First, multiply 45 by $\frac{3}{5}$

$\frac{45}{1} *\frac{3}{5}$

$\frac{135}{5}$

27 games.

You could also just multiply 45 by 3 then divide by 5. Mostly the same thing

I hope this helps!

2. 27 $cm^{3}$

3. 30

Step-by-step explanation:

Area = $\pi$ $r^{2}$

= $\pi$ x $10x^{2}$

= 100 $\pi$

Volume = l x w x h

= 3 x 3 x 3

Determine the value of x. 1) 14.75 2)15.25 3)11.92 4)18.56

Leto [7]

Opposite angles are supplementary, the sum is 180 degrees.
6x+10+81.5=180
Combine like terms:
6x+91.5=180
Subtract 91.5 to both sides:
6x=88.5
Divide 6 to both sides:
x=14.75
The answer is 1) 14.75
Hope this helped!

What is the equation for the line of reflection? On a coordinate plane, triangle A B C has points (6, 3.7), (5.4, 2), (1, 3). Tr

elixir [45]

Answer:

The equation for the line of reflection will be x = y.

Step-by-step explanation:

On a coordinate plane, triangle Δ ABC has points (6, 3.7), (5.4, 2), (1, 3). Triangle Δ A'B'C' has points (3.7, 6), (2, 5.4), (3, 1).

And we have to find the equation of the line of reflection of the points.

Now, it is clear from the coordinates of vertices of Δ ABC and Δ A'B'C' that after reflection the x and y-values of the respective coordinates interchange and there is no change in signs.

Therefore, the equation for the line of reflection will be x = y. (Answer)
