mafiozo [28]

Answer:

m∠2 = 57°

Step-by-step explanation:

From the triangle given in the picture,

By applying triangle sum theorem in ΔABC,

m∠BAC + m∠ABC + m∠BCA = 180°

90° + m∠2 + 33° = 180°

m∠2 + 123° = 180°

m∠2 = 180° - 123°

m∠2 = 57°

It will take Adam four hours to drive to Disney Park, and 2.5 times less time if driving 45 mph faster. What is the distance Ada
Butoxors [25]
<h2>Hello!</h2>

The answer is:

The distance that Adam should cover to get to the park is 108 miles.

<h2>Why?</h2>

To solve the problem, we need to write two equations with the given information about the times and his speed.

So,

For the first equation we have: Going to Disney Park

time=4hours

Distance=v*4hours

For the second equation we have: Going back from Disnery Park

time=4hours-2.5hours=1.5hours

Speed=v+45mph

Distance=(v+45mph)*1.5hours

Now, if He covered the same distance going and coming back, we have:

v*4hours=(v+45mph)*1.5hours

v*4hours=v*1.5hours+45mph*1.5hours

v*4hours-v*1.5hours=45mph*1.5hours

v*2.5hours=67.5miles

v=\frac{67.5miles}{2.5hours}=27\frac{miles}{hour}=27mph

We have that the speed when Adam was going to Disney Park was 27 mph.

Therefore, to calculate the distance, we need to substitute the obtained speed in any of the two first equations.

Then, substituting the speed into the first equation, we have:

Distance=v*4hours\\Distance=27mph*4hours=108miles

Hence, we have that the distance that Adam should cover to get to the park is 108 miles.

Havea nice day!

together, jason and mara have $74. jason has $6 more than 1/3 as much money as Mara has. how much does each person have?
alina1380 [7]
Make an equation system based on the problem
<span>Jason and Mara have $74
</span>⇒ j + m = 74
<span> Jason has $6 more than 1/3 as much money as Mara has
</span>⇒ j = (1/3)m + 6
<span>
Then, solve the equation by subtitution
j + m = 74
(1/3)m + 6 + m = 74
(1/3)m + m = 74 - 6
(1/3)m + (3/3)m = 68
(4/3)m = 68
m = 68 </span>÷ 4/3
m = 68 × 3/4
m = 51
Mara has $51

j + m = 74
j + 51 = 74
j = 74 - 51
j = 23
Jason has $23
