Given:
In triangle [tex]FJH,KG\parallel JH, FK=3, KJ=15,\text{ and }FG=4.[/tex]
To find:
The length of [tex]FH[/tex].
Solution:
Basic proportionality theorem(BPT): If a line intersect the two sides of a triangle and parallel to third side of the triangle, then it divides the sides proportionally.
In triangle [tex]FJH,KG\parallel JH[/tex].
Using BPT, we get
[tex]\dfrac{FK}{KJ}=\dfrac{FG}{GH}[/tex]
[tex]\dfrac{3}{15}=\dfrac{4}{GH}[/tex]
On cross multiplication, we get
[tex]3\times GH=4\times 15[/tex]
[tex]GH=\dfrac{60}{3}[/tex]
[tex]GH=20[/tex]
Now,
[tex]FH=FG+GH[/tex]
[tex]FH=4+20[/tex]
[tex]FH=24[/tex]
Therefore, the length of FH is 24 units.
Please help :)

A recipe for 12 cupcakes uses 2/3 cups of sugar. The number of cupcakes is directly proportional to the amount of sugar. How many cupcakes can you make with 3 cups of sugar?
help please!! i need an answer before may 7th
Answer:
54 cupcakes
Step-by-step explanation:
You would see how much sugar goes into each cupcake which is 1/18 cups of sugar in each cupcake, next you would see how many cupcakes you can make by turning the total 3 cups of sugar into an improper fraction of 54/18, then you would see how many times 1/18 can go into 54/18 which is 54 times meaning that with 3 cups of sugar you can make a total of 54 cupcakes.
Definitely could use some help. Would also be really appreciated if someone gave a breakdown of how they solved it. Thank you!!!
Answer:
x = 10Step-by-step explanation:
Parallel lines cut the transversals into proportional sections.
Find the ratios of the corresponding parts and solve for x:
(3x - 5)/(28 - 8) = 10/8(3x - 5)/20 = 5/43x - 5 = 20*5/43x - 5 = 253x = 30x = 10The number of parking spots, y, in the local town x years from now can be modeled by the equation below. How

Answer:
x = [tex]-\frac{1}{3}[/tex], y = 2
Step-by-step explanation:
3x + 3y - 7 = 12x + y
6y - 12x - 1 = -45x
(3x - 12x) + (3y - y) = 7
(-12x + 45x) + 6y = 1
-3(-9x + 2y = 7)
33x + 6y = 1
27x - 6y = -21
33x + 6y = 1
60x = -20 -> x = -20/60 = -1/3
-9x + 2y = 7 -> y = [tex]\frac{7+9x}{2}[/tex] = [tex]\frac{7+9*-\frac{1}{3}}{2}[/tex] = 2

Step-by-step explanation:
Henry is making a corn grits recipe that calls for 1/4 cup of corn grits for every 1/2 cup of water. How much water will he need if he uses 1 1/2 cups of corn grits?
Expand 1/2 to 2/4, if there is 1 1/2 cups of corn grits, that means that 1/4 cups of corn grits was used 6 times, 1/2x6=3. He will need 3 cups of water

A school sport's team sold hats for $12 each hat. The team made a profit of $3 for each hat sold. What percent of the selling price of each hat is the profit?
Answer: 25%
Step-by-step explanation:
Given: Selling price of each hat = $12
Profit on each hat = $3
To find: The percent of the selling price of each hat is the profit.
Ratio of profit to selling price = [tex]\dfrac3{12}=\dfrac14[/tex]
The required percentage = Ratio of profit to selling price x 100
[tex]=\dfrac14\times100=25\%[/tex]
The profit is 25% of the selling price.
