Answer: d) 5/7

Step-by-step explanation:

10 out of 35 of the students are girls. The number of boys is therefore:

= 35 - 10

= 25 boys

Probability that the winner is a boy is:

= 25/35

Take that fraction to the simplest by dividing both by 5:

= 5/7

Find the value of 7v-10 given that -11v-7=4. Simplify your answer as much as possible.
densk [106]

First thing to do is solve the given equation for v

-11v-7 = 4

-11v = 4+7

-11v = 11

v = 11/(-11)

v = -1

Once we know this, we can use it to compute the following

7v-10 = 7*(-1) - 10 = -7 - 10 = -17

--------------------------------

Answer: -17

In the diagram, BC¯¯¯¯¯∥DE¯¯¯¯¯ .<br><br> What is AE ?
emmainna [20.7K]
So there are two triangles here: Smaller one (ADE) and bigger one (ABC) and they both are similar.

So you can use proportions here.

AB / AC = AD / AE

AB = AD + DB = 6 + 1 = 7
AC = AE + 3

AD = 6

So plug in these values:

AB / AC = AD / AE becomes
7 / (AE + 3) = 6 / AE

Now do the cross multiply:

7 AE = 6 (AE + 3)

Now solve for AE:

7AE = 6AE + 18

AE = 18
