At a country concert, the ratio of the number of boys to the number of girls is 2:7. If there are 250 more girls than boys, how many boys are at the concert?

Answers

Answer 1

Answer: Boys : Girls = 2:7
let the no. of boys be x
so no of girls = 250+x
so, x:(250+x) = 2:7
x/(250+x) = 2/7
7x = 500+2x
7x-2x = 500
x = 500/5 =100

Question 3 (1 point)Cynthia drove 12 miles in 4.8 minutes. How long would it take her to drive 37 miles? "

Answers

Answer:

14.8 minutes

Step-by-step explanation:

4.8 min/12mi= 0.4 min/1 mile driven

multiply the time by the distance:

37mi*(.4min/1mi), mi cancels and you're left with min

37*0.4=14.8 min

D=RT; 12=R*(.08 hours); R=150mph
Now, 37=150*T; T=37/150=14.8 minutes

The cubic parent function y=x^3 contains the point (2,8). If the function reflected over the x-axis and shifted right 6 units, what are the coordinates of the new point

Answers

Answer:

The new coordinate are (8,-8)

Step-by-step explanation:

Whenever a graph is reflected about the x-axis, positive y values become negative and vice versa. In this case positive y(8) becomes negative (-8). While the x values remain unchanged.

So the coordinates when moving by one unit will be (2,-8)

Shifting it 6units to the right increases the x values by six to give the new coordinates which is (8,-8)
