Answer:
48.52
Step-by-step explanation:
SOHCAHTOA
Use tan(x) = opposite / adjacent
tan (15) = 13/x
x = 13/ tan(15)
x = 48.5166605 round to 48.52
*when using calculator don't forget to use degrees not radians or you will get the wrong answer*
Answer:
x=48.517
Step-by-step explanation:
x= 13/tan 15 degrees
x= 48.5166605
Round to x=48.517

Answer:
Sure thing! If you are trying to find the area then multiply the height of the shape by the width, If you are trying to find the perimeter of the shape the add the lengths of all four sides, If you are trying to find the volume of the shape then you need to multiply the length by the width of the shape.
Step-by-step explanation:
Height x width = Area add the length to all four sides = perimeter Length x width = Volume

A truck traveling 45 miles per hour and a train traveling 60 miles per hour cocer the same distance. The truck travels 2 hours longer than the train. How many hours does the each travel? What equation would represent the total distance traveled by both the train and the truck?
Answer:
Train time = 6 hours
Truck time = 8 hours
60x = 45x + 90
Step-by-step explanation:
Train speed = 60mph
Truck speed = 45 mph
Let distance covered = d
Let travel time of train = x
Travel time of truck = x + 2
Total distance traveled :
Distance = speed * time
Train distance = truck distance
60 * x = (45 * (x + 2))
60x = 45x + 90
60x - 45x = 90
15x = 90
x = 90/15
x = 6
Train time = 6 hours
Truck time = 6 + 2 = 8 hours
Distance traveled :
60x = 45x + 90
60 * 6 = (45*6) + 90
360 = 270 + 90
360 = 360
Vanessa bought a laptop at a 20% discount. The original price of the laptop was $275.00. How much money did Vanessa save?
Answer:
$55.00
Step-by-step explanation:
20% of 275 is 55. Meaning she saved 55 dollars.
Answer:
Vanessa saved $55, and she only had to pay $220.
Step-by-step explanation:
First we need to convert 20% into a decimal, 0.20.
Now we need to multiply 275 and 0.20.
275 × 0.20 = 55
275 - 55 = 220
Pleasee help(GIVING BRAINILEST) Tyra's family is spending the afternoon in Millersville. They plan to see a movie and then explore the town. The movie will cost the family $36, and parking costs $4 per hour.
How long will the family be able to spend in Millersville if they want to spend less than $60 and they don’t have any other expenses?
Follow the steps to answer this question.
1. Write an inequality that shows that Tyra's family spends less than their limit. Explain how you wrote the inequality, and define any variables used. (2 pts)
Write your answer in the space below.
2. Solve your inequality. Show your work. What does your solution mean? (3 pts)
Write your answer in the space below.
Answer:
1.) 4x + 36 < 60
2.) The family must spend less than 6 hours in Millersville watching the movie.
Step-by-step explanation:
1.) In order to write an inequality to represent the situation, we need to consider all variables. The main resultant / dependent variable is the money spent. The independent variable is the time.
Let x = time and y = money spent.
y = mx + b
Since the entrance fee for the movie is $36, we know that the b = 36. Since the rate of change is $4, you know that m = 4. Lastly, since the maximum amount of money the family has is $60, y = 60.
60 = 4x + 36
Finally, since the money spent must always be LESS THAN 60, 4x + 36 < 60
2.) Soling the Inequality:
Firstly, isolate the 4x by subtracting 36 from both sides.
4x + 36 -36 < 60 - 36
4x < 24
Next, divide both side by 4 in order to isolate x. Since 4 is positive, DO NOT flip the less than
4x/4 < 24/4
x < 6
Since x represents the time, time < 6 hours, meaning that the family must spend less than 6 hours in Millersville watching the movie.
Answer:
1. 60>4x+36
2.6>x
Step-by-step explanation:
60 is the total amount of money the family has to spend, they want to spend less than that so...
60 is greater than what they will spend (60>)
the (x) is the amount of hours the family will spend at the city. parking cost 4 so that means 4 dollars per hour.
the 36 is what they have to initially spend to watch the movie
if you subtract both sides of the (>) by 36 you get
24>4x
then you divide both sides by 4 to get the (x) by itself, which gets you
6>x
meaning that the amount of hours the family will spend at the city will have to be 5 hours
correct me if I'm wrong but i believe that this is the correct answer... i double checked

Please mark me BrainIIest
Step-by-step explanation:
1.I will solve your system by substitution.
−x+2y=6;6y=x+18
Step: Solve−x+2y=6for x:
−x+2y+−2y=6+−2y(Add -2y to both sides)
−x=−2y+6
[tex]\frac{-x}{-1} =\frac{-2y}{-1}[/tex] Divide by -1
x=2y−6\
Well I did this problem differently I substitute
Step: Substitute2y−6for x in6y=x+18:
6y=x+18
6y=2y−6+18
6y=2y+12
6y+−2y=2y+12+−2y
4y=12
[tex]\frac{4y}{4} =\frac{12}{4}[/tex]
y=3
Step: Substitute3 for y in x=2y−6:
x=2y−6
x=(2)(3)−6
x=0
Your final answer will be x=0 and y=3

(1) Aeroplane A travels 1220 km in 3.5 hours. Aeroplane B travels 830 km in
2.5 hours. Which aeroplane travels faster?
Answer:
Aeroplane A
Step-by-step explanation:
To find the km traveled per hour, divide 1220 by 3.5 and divide 930 by 8.5. When we do this, we have the numbers 348.571428571 for plane A and 109.411764706 for plane B. Since 348>109, plane A travels faster. I hope this helps!

Find the value of x and y
Answer:
Answer: x = 33, y = 81..........
You can see that the two lateral and vertical sides of the quadrilateral are congruent respectively, meaning that ∠3x = ∠(2x+33).
You also know that 3x + y = 180° since they're supplementary.
To solve for x, just solve the equation I wrote above:
3x = (2x+33) (subtract 2x from both sides, and that automatically gives you
x = 33 the value)
To solve for y, plug it into the second equation I provided:
3(33) + y = 180
99 + y = 180
y = 81
∴ x = 33, y = 81
An artist has a total of 80 paintbrushes, 22 of them are flat brushes, used
for blending. What percent of the artists' paintbrushes areflat brushes?
Answer:
27.5%
Step-by-step explanation:
To find what percent a part is of the whole, divide the part by the whole and multiply by 100%.
percent = part/whole * 100%
percent = 22/80 * 100%
percent = 0.275 * 100%
percent = 27.5%
Answer: 27.5%
Since we know the total which is 80 (which would be 100% in percents), and we want to find the percentage of 22 flat brushes.
We want to find 22 out of 80 written as a percent value?You have to convert fraction (ratio) 22 / 80
Answer: 27.5%
