Answer:
The measure of the acute angle is 18.4°
Step-by-step explanation:
The angle between a line of equation y = m x + b and the positive part of the x-axis is Ф = [tex]tan^{-1}[/tex](m), which means tan Ф = m, where m is the slope of the line
Let us use this rule to solve the question
∵ A line of equation y = [tex]\frac{1}{3}[/tex] x + 4 makes with a horizontal line an acute ∠
→ Compare the equation of the line by the form of the equation above
∴ m = [tex]\frac{1}{3}[/tex]
→ Assume that the acute angle is Ф
∴ The acute angle between the line and the horizontal line is Ф
→ By using the rule above
∵ tan Ф = m
∴ tan Ф = [tex]\frac{1}{3}[/tex]
→ Use [tex]tan^{-1}[/tex] to find Ф
∵ Ф = [tex]tan^{-1}[/tex] ( [tex]\frac{1}{3}[/tex] )
∴ Ф = 18.43494882
→ Round it to the nearest tenth
∴ Ф = 18.4°
∴ The measure of the acute angle is 18.4°

Leo made a 59, 84, 61, and an 81 on the first four tests. What score
would he have to make on the 5th test in order to make at least an 85
in the course?
Answer:
71
Step-by-step explanation:
59 add 84 add 61 add 81 is 285
285 divided by (how many test scores) 4 is 71.25
I then rounded the number to 71. So leo would get 71. This is called mean. The mean is basically adding all the numbers then dividing it by how many there were of numbers. Mean tells you the average. So I'm pretty sure it's 71.

help plssssss i will pin u
Answer:
The answer is 7.
Explanation:
The answer is 7, because [tex]\frac{7}{14} -\frac{4}{14} =\frac{3}{14}[/tex]. If the fractions have common denominators (14) then just subtract the numerators like a regular subtraction problem, and 7 minus 4 equals 3, so 7 is the answer.

As an estimation we are told 5 miles is 8 km.
Convert 36 km to miles.
Answer:
22
Step-by-step explanation:
Answer:
Step-by-step explanation:
I will first answer your question with the data you have provided, then offer two other ways to solve the problem with alternative data:
You have stated that 5 miles is approximately 8 kilometers. As a ratio this is 5 mi / 8 km
Now create a proportion :
5 mi / 8 km = X mi / 60 km
Miles is to kilometers as miles is to kilometers.
Now cross multiply to solve for X.
8 X = 300
X = 37.5 miles
There are several other ways we can answer this question

A company earned a profit of 880,000 last year and 970,000 this
year. What is the percent change in a profit between the two years?
pls help due today:(
Please explain:(
Answer:
-9.28%
Step-by-step explanation:
Subtract the prior accounting period's profit from the current accounting period's profit. The result gives you the numerical change in profit.
970000-880000= 90000
90000 in percentage = -9.28%
Answer:
-9.28%
Step-by-step explanation:
Subtract the prior accounting period's profit from the current accounting period's profit. The result gives you the numerical change in profit.
970000-880000= 90000
90000 in percentage = -9.28

Sound travels through air at about 344 meters per seconds when the temp. is 20 degrees c. If Enrique lives 2 kilometres from the fire station and it takes 5 seconds of the fire station siren to reach him, how can you prove indirectly that it's not 20 degrees Celsius when Enrique hears the siren?
The temperature at the time the siren sounded is not 20 degrees c because, the speed of the siren sound is 400 meters per second, contrary to the speed of sound at 20 degrees c, 344 meters per seconds.
According to the question:
At 20 degrees c, sound travels throughout air at about 344 meters per seconds.However, Enrique's house is 2 kilometres from the station and it takes 5 seconds for the fire station siren to reach him.
In essence, the speed of the siren sound is;
Speed = 2,000/5 = 400 meters per second.
Ultimately, since the speed of the siren sound is 400 meters per second, contrary to the speed of sound at 20 degrees c, 344 meters per seconds.
We can conclude that the temperature is not 20 degrees c.

Answer:
5:03
Step-by-step explanation:
it dosnt say anything about time zones so im going to assume they are using the same time
2:46 is time flight leaves
after 2 hours 17 minutes it arrives
add 2:17 minutes to 2:46 to get answer
2:46
2:17

The minute hand of a clock is 6 inches long. How far does the tip of the minute hand move in 15 minutes? How far does it move in 25 minutes?
Answer:
Step-by-step explanation:
angle subtended at center in 15 minutes=360÷60×15=90°=π/4
distance traveled by minute hand=2πr/4=πr/2=6π/2=3π inches≈9.42 inches
distance travelled by minute hand in 25 minutes=2πr×25/60=50πr/60=5/6πr
≈5/6 π×6=5π inches ≈15.71 inches
