Who knows how to do this I TRULY NEED HELP
Answer:
x = 10
Step-by-step explanation:
It's given in the question that both the traingles JCD & JKL are similar. So their ratio of corresponding similar sides will be proportional to each other.
[tex] = > \frac{JD}{JL} = \frac{JC}{JK} = \frac{DC}{LK} [/tex]
[tex] = > \frac{15}{50} = \frac{8 + x}{60} = \frac{DC}{LK} [/tex]
[tex] = > \frac{15}{50} = \frac{8 + x}{60} [/tex]
[tex] = > 8 + x = \frac{15 \times 60}{50} = 18[/tex]
[tex] = > x = 18 - 8 = 10[/tex]

Answer:
c. [tex]1\leq x\leq 6[/tex]
Step-by-step explanation:
the domain is the set of all possible inputs of a function, in other words, all the x-values that make up the function. in this function, the first x-value is 1, and the function is continuous all the way up to 6, so, the domain would be the answer in c.
use your knowledge of angle relationships solve for x in the diagram below Justify Your solution by naming the geometric relationship
Answer:
x = 5°
Step-by-step explanation:
5x + 21° + 20x + 34° = 180°
25x + 55° = 180°
25x = 180° - 55°
25x = 125°
x = 125°/25
x = 5°
Hope you got it dear !!!!
Geometric relationship is supplementary angles. Supplementary angles sum up to 180 degrees.
The value of x is 5.
Using the geometric relationship between two angles in the image given, we can create an equation that will enable us solve to determine the value of x in the figure given.Thus:
[tex]5x + 21^{\circ}[/tex] and [tex]20x + 34^{\circ}[/tex] are angles on a straight line.The geometric relationship between them is:[tex](5x + 21) + (20x + 34) = 180^{\circ}[/tex] (angles on a straight line are supplementary)
Solve for x[tex]5x + 21 + 20x + 34 = 180[/tex]
Add like terms[tex]25x +55 = 180[/tex]
Subtract 55 from each side[tex]25x = 180 - 55\\\\25x = 125[/tex]
Divide both sides by 25[tex]x = 5[/tex]
Therefore the geometric relationship between the angles is that they are supplementary. They equal 180 degrees.The value of x is 5Learn more here:

At the local candy store, Harper bought 4 ounces of jelly beans for $15.96. At that rate, how much would she pay for 7 ounces of jelly beans beans?
Answer:
$27.93
Step-by-step explanation:
First we divided 4 from 15.96 and got 3.99, so now we know that $3.99 is how much each ounce of jellybeans costs so now we multiply 3.99 times 7 to get our answer of 27.93.
Solve for x and then solve for y.
Answer:
y = 62
Step-by-step explanation:
Since we need to solve for x first, we'll solve the left triangle first. A triangle equals 180 degrees, so with in mind:
x + 7 + 3x - 18 + x - 9 = 180
add like terms
5x - 20 = 180
add 20 to both sides
5x = 200
divide by 5
x = 40
Now we have x, input it into the equations for the second triangles:
x + 21 + x + 17 + y = 180
40 + 21 + 40 + 17 + y = 180
add/simplify
118 + y = 180
subtract 118 from both sides
y = 62
Answer:
x = 40° ; y = 62°
Step-by-step explanation:
The figure consists of 2 triangles. According to Angle sum property in a triangle , sum of measure of all the angles of a traingle is equal to 180° .
So ,
[tex](3x - 18) + (x + 7) + (x - 9) = 180[/tex]
[tex] = > 5x - 20 = 180[/tex]
[tex] = > 5x = 180 + 20 = 200[/tex]
[tex] = > x = \frac{200}{5} = 40[/tex]
Now using the angle sum property in another triangle ,
[tex](x + 21) + (x + 17) + y = 180[/tex]
[tex] = > y + (40 + 21) + (40 + 17) = 180[/tex]
[tex] = > y + 61 + 57 = 180[/tex]
[tex] = > y + 118 = 180[/tex]
[tex] = > y = 180 - 118 = 62[/tex]

A bicycle store costs $2250 per month to operate. The store pays an average of $40 per bike. The average selling price of each bicycle is $70. How many bicycles must the store sell each month to break even?
Answer:
75
Step-by-step explanation:
Given That :
Operation cost = $2250 per month
Purchase price per bike = $40
Average selling price per bike = $70
How many bicycles must the store sell each month to break even ;
Break even point = point at which there is net profit / loss = 0
Let number of bicycles store must sell = x
Operation cost + (purchase price * Number of bicycles) = selling price * Number of bicycles
2250 + 40x = 70x
2250 = 70x - 40x
2250 = 30x
x = 2250 / 30
x = 75
To break even 75 bicycles must be sold

You received a 85, 88, and a 94 on your last three math exams. What grade would you need on your next exam to have an average of 90? (Show all work on your scratch paper and make sure you set up an equation)
You would need to get a ??????
to have an average of 90%.
Answer: 93
suppose: the grade we need on the next exam is x (x > 0)
to have an average of 90, we have the equation:
[tex]\frac{85+88+94+x}{4}=90\\\\<=>267+x=360\\\\<=>x=360-267\\\\<=>x=93[/tex]
so the grade we need on the next exam is 93
Step-by-step explanation:
[tex]suppose: the grade we need on the next exam is x (x > 0)
to have an average of 90, we have the equation:
\begin{gathered}\frac{85+88+94+x}{4}=90\\\\ < = > 267+x=360\\\\ < = > x=360-267\\\\ < = > x=93\end{gathered}485+88+94+x=90<=>267+x=360<=>x=360−267<=>x=93
so the grade we need on the next exam

What is the answer.........
Answer:
1 is correct
2 is correct
3 is incorrect
4 is incorrect
5 is correct
Step-by-step explanation:
1 is correct because the statue lies the same distance from both entrances.
2 is correct because B is also the same distance from both entrances.
3 is the opposite of 2, saying that B is not equal distance from both entrances, making it false.
4 is incorrect because a is closer to the upper entrance.
5 is correct because it is basically the same question as 2, saying b is the same distance from both entrances.
