1. You and your friend are going to Boston but have to drive separately. You both want to
leave at 10am and want to arrive in Boston at
4pm. To get there you have to drive 240 miles
and your friend will drive 300 miles. At what
rates do you and your friend have to drive?

speed acquired by me = 40 miles / hour

speed acquired by my friend = 50 miles / hour

Step-by-step explanation:

Here's the solution :-

time taken by both = 6 hours

( 10 AM - 4 PM )

1. Now, the required speed for me to reach boston at 4 PM is :

=》

=》

=》

2. Now, the required speed for my friend to reach boston at 4 PM is :

=》

=》

=》

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
