[tex]\Large\boxed{\tt Answer:~Isosceles~Triangle;~x=25}[/tex]
[tex]\tt Step-by-step~explanation:[/tex]
Since this triangle has two congruent angles/sides, we know that it is an isosceles. We can tell by looking at the markings on the triangles: The curves on both angles A and C indicate that they are congruent, and the markings on lines AB and CB also tell us that they are congruent.
To solve for x, we set up our equation like this:
[tex]\tt 4x-20=2x+30[/tex]
Since we know that lines AB and CB are congruent, that means 4x - 20 is equal to 2x + 30.
To solve, we can first subtract 2x from both sides and add 20 to both sides.
[tex]\tt 4x-(2x) -20=2x-(2x)+30\\2x-20+(20)=30+(20)\\2x=50[/tex]
Then, we divide both sides by 2 to isolate x.
[tex]\tt \frac{2x}{2} \frac{50}{2} \\x=25[/tex]
We can check if our answer is correct by plugging in our value for x into both expressions and see if they equal the same thing.
[tex]\tt 4(25)-20=80\\2(25)+30=80\\Correct[/tex]

A tree cast a shadow 64 feet long. At the same time, a girl 5 feet tall
standing near the tree cast a shadow that is 8 feet long. Which of the
following represents the height of the tree?
F. 61 feet
G. 51 feet
H. 40 feet
J. 25 feet
Answer:
40 feet represents the height of the tree ⇒ H
Step-by-step explanation:
Let us solve the question using the proportional
∵ A tree casts a shadow 64 feet long
∴ L[tex]_{T}[/tex] = 64 feet
∵ At the same time, a girl 5 feet tall standing near the tree
∴ H[tex]_{G}[/tex] = 5 feet
∵ She casts a shadow that is 8 feet long
∴ L[tex]_{G}[/tex] = 8 feet
The ratios between the shadows and the heights of the tree and the girl are proportional
∵ [tex]\frac{H_{T}}{H_{G}}[/tex] = [tex]\frac{L_{T}}{L_{G}}[/tex]
→ Substitute their values in the equivalent ratios
∴ [tex]\frac{H_{T}}{5}[/tex] = [tex]\frac{64}{8}[/tex]
→ By using cross multiplication
∴ H[tex]_{T}[/tex] × 8 = 5 × 64
∴ 8H[tex]_{T}[/tex] = 320
→ Divide both sides by 8
∴ H[tex]_{T}[/tex] = 40 feet
∴ 40 feet represents the height of the tree

Find the measure of angle R
Answer:
since all sides are congruent the you could divide 180 by the because there are 180 degrees in a triangle
So the measure of angle R is 60 degrees
A salesgirl is paid a basic wage of $140 per
week. In addition, she is paid a commission of
5% on the value of goods she sells. How much
commission will she be paid on sales amount-
ing to $1 525 and what is her gross wage for the
week?
Answer:
This week her gross wage is equal to $216.25
Step-by-step explanation:
From the question it self we can make the following equation.
Let "W" be the gross wage for the week.
Let "V" be the value of the goods she sells.
then.....
W = $140 + 0.05V
(Where $140 is the price she will be paid for just working and 0.05V is the commission she will get paid this week)
Now that we know what "v" equal to, we can easily find out her Gross Wage this week by inserting in the value of V. And so we get.......
W = $140 + 0.05V
W = $140 + 0.05 x 1525
W = $140 + 76.25
W = $216.25

Which line has a constant of proportionality between Y and X of 1
Answer:
Line B
Step-by-step explanation:
The line B has a proportionality of one which you can tell because of the equation Y=1X. Simplified, this equation means that for every increase in X value, there is an equal increase in Y value. This equation can be used to find the proportionality rate of other lines such as how A is Y=2X and C is Y=1/2X.

55 per cent of the students in a school are girls. What percentage of the students are boys? Find the number
of students, if there are 216 boys
Answer:
Percentage of boy students is 45 per cent.
The total number of students is 480.
Step-by-step explanation:
To find the percentage of boy students, just subtract 55% (the percentage of girl students) from 100%, then you'll get 45%.
To find the total number of students, just use algebraic equation, rearrange it, and solve for x.
The workings are shown in the picture attached. Hope this helps!
Answer:
total of students is 480
Step-by-step explanation
let t = total of students.
if 55% of the students in school are girls.
then 45% of the students in the school are boys.
if there are 216 boys in school.
[tex]45\% \times t = 216 \\ t = \frac{216}{45\%} \\ t = \frac{216}{ \frac{45}{100} } \\ t = \frac{216 \times 100}{45} \\ t = 480[/tex]

Solve each quadratic equation by factoring.
Show steps pls
8x^2 - 4x = 2x +9
Answer:
hope these help........
Answer:
[tex]x = \frac{-3}{4}[/tex] or [tex]x = \frac{3}{2}[/tex]
Step-by-step explanation:
[tex]8x^{2} - 4x = 2x +9[/tex]
Okay, let's put everything on one side.
[tex]8x^{2} -4x-2x-9=0[/tex]
As you can see we can subtract -4x from -2x now leaving us with -6x.
[tex]8x^{2} -6x-9=0[/tex]
Now there are multiple ways to solve a polynomial, but we can go with a way to factor them the easy way. We need to multiply the leading coefficient with the ending term because there is no common number we can factor out of these guys.
[tex]8(-9)=-72[/tex]
We multiplied 8 and -9 together which gave us -72. With this, we need to find two numbers that add to the middle term, -6, but will multiply to -72. This is going to be 6 and -12. Now we are going to replace the middle coefficient with those two numbers.
[tex]8x^{2} + 6x - 12x- 9= 0[/tex]
(Keep in mind the equation has not changed)
Now we are going to do something called factoring by grouping, with the first two terms, 8x^2 and 6x we take out the GCF (greatest common factor):
[tex]2x(4x+3)[/tex]
so let's do the same between the last two.
[tex]-3(4x+3)[/tex]
So when putting them together we have,
[tex]2x(4x+3)-3(4x+3)=0[/tex]
Now let's factor here, (4x+3) can be taken out and 2x as well as -3 can be put together.
[tex](4x+3) (2x-3)=0[/tex]
Then we set these factors to zero to get our x answer:
[tex]4x+3=0[/tex]
[tex]2x-3=0[/tex]
And we solve, which leaves us with:
[tex]x = \frac{-3}{4}[/tex] or [tex]x = \frac{3}{2}[/tex]
What is the slope of the line?
Answer:
Slope = [tex]-\frac{1}{3}[/tex]
