Answer:

34°

Step-by-step explanation:

If m∠ADE is with 34° smaller than m∠CAB, then denote

m∠ADE=x°,

m∠CAB=(x+34)°.

Since  DE ║ AB, then

m∠ADE=m∠DAB=x°.

AD is angle A bisector, then

m∠EAD=m∠DAB=x°.

Thus,

m∠CAB=m∠CAD+m∠DAB=(x+x)°=2x°.

On the other hand,

m∠CAB=(x+34)°,

then

2x°=(x+34)°,

m∠ADE=x°=34°.

A venue plans to host trucking events regularly throughout the year. The expected revenue from each event is $100,000. The cost
iris [78.8K]

Answer:

The venue has to host 47 events throughout the year

Step-by-step explanation:

Profit:

Profit is revenue subtracted by costs.

Per event:

$100,000 revenue

$50,000 costs

$100,000 - $50,000 = $50,000 profit.

If the venue wants to make a total profit margin of $2,350,000, how many events does the venue have to host throughout the year?

1 event - $50,000 profit.

x events - $2,350,000 profit.

50000x = 2350000

x = \frac{2350000}{50000}

x = 47

The venue has to host 47 events throughout the year

Makovka662 [10]

Answer:

Pattern A start at 0 and uses the rule "Add 2"

Pattern B starts at 0 and uses the rule "Add 3"

Step-by-step explanation:

Given that Tai wrote 2 patterns  then she made the corresponding numbers into ordered pairs and graphed them below. We have to find the pattern before ordering.

Now, the x-axis coordinates are 0, 2, 4, 6, 8

The pattern is A starts at 0 and uses the rule Previous value+2 i.e uses the rule "Add 2"

Now, the y-axis coordinates are 0, 3, 6, 9, 12

The pattern is B starts at 0 and uses the rule Previous value+3 i.e uses the rule "Add 3"
