An artist is working on the design of a logo for the T-shirts that the participants in the walk will receive. He starts by drawing ∠ADC so that it measures 60°. Next, he draws DB so that m∠BDC is 10° greater than m∠ADB. c. What postulate did you make use of to answer parts a and b? How did this postulate help you write an equation that could be solved for x?

452,489 to the nearest thousand is 452,000

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75
