For The Pair Of Similar Triangles, Find The Value Of X.2x-439x+624

Answers

Answer 1

Answer:

x= 20

Step-by-step explanation:

set up a proportion:

(2x - 4)/24 = 39 / (x + 6)

(2x - 4)(x + 6) = 936

2x^2 + 8x - 24 = 936

x^2 + 4x - 12 = 468

x^2 + 4x - 480 = 0

(x - 20)(x + 24) = 0

x= 20, -24

has to be positive so x = 20

Question??

Dr. Sox drives through two stoplights on her way to work. The first light is green for 20 seconds out of each minute. The second light is green for 35 seconds out of each minute. What is the probability that Dr. Sox will hit two green lights?

Explanation;

Since this is an AND situation, we MULTIPLY the probabilities.

Answer/Explanation:

First light green:

P

1

=

20

60

=

3

Second light green:

P

2

=

35

60

=

Both lights green:

Of course, this is assuming that there is no "green wave" policy, or the two probabilities would not be independent

Anna is following this recipe to make biscuits.
Anna uses 660 mL of syrup.
How many grams of margarine will she need?

Recipe: Makes 24 biscuits
60 g sugar
110 mL syrup
220 g oats
120 g margarine
40 g chocolate​

Answers

Answer:

720 grams

Step-by-step explanation:

660 mL(amount she used) / 110 mL (amount from the recipe) = 6 times

So Anna uses 6 times the amount of syrup from the recipe.

Therefore she also needs 6 times more margarine than it is written in the recipe, which is 120 g * 6 = 720 g

Ron and Howard work at Amazon. Ron works x hours per day each week (7days). Howard works one more hour each day, than Ron. Which expressions calculate the number of hours Howard works in a week

Answers

Answer:

Howard works 7x+7 hours in a week

Step-by-step explanation:

Equations

Ron and Howard work at Amazon.

Ron works x hours each week for 7 days. This means he works 7x hours a week.

Howard works one more hour per day than Ron, thus he works x+1 hours per day. This means he works 7(x+1)=7x+7 hours a week.

Howard works 7x+7 hours in a week

wants to leave the waitress a 20% tip. How much would he leave for a tip?
