Jessica divides the ribbon in three parts out of which length of one part = [tex]3\frac{1}{2}[/tex] inches
Let the length of other two parts = x inches
Total length of whole ribbon = 12 inches
[tex]3\frac{1}{2}+x+x=12[/tex]
[tex]3\frac{1}{2}+2x=12[/tex]
[tex]2x=12-3\frac{1}{2}[/tex]
[tex]2x=12-\frac{7}{2}[/tex]
[tex]2x=\frac{24-7}{2}[/tex]
[tex]2x=\frac{17}{2}[/tex]
[tex]x=\frac{17}{4}[/tex]
[tex]x=7\frac{1}{4}[/tex] inches
Therefore, option A will be the answer.

Answer:
49
Step-by-step explanation:
4^3=64
5(-3)=-15
64+(-15)=49
Answer:
49
Step-by-step explanation:
First, because of the order of operations, you would do 4^3 (or four to the power of three) first to get 64. 5×-3 is equal to -15, and a positive number plus a negative number is just that positive number minus a positive version of the negative number, if that even makes sense. Basically, 35 + -2 would be equal to 35-2. 64-15 is equal to 49, which is your answer!
I hope this helped you!

Answer:
-13, -3
15, 2.6
Step-by-step explanation:
x, y are the numbers
x = 5y + 2
x×y = 39
(5y + 2)×y = 39
5y² + 2y - 39 = 0
the solution of a quadratic equation :
y = (-b ± sqrt(b² - 4ac))/2a
a = 5
b = 2
c = -39
y = (-2 ± sqrt(2² - 4×5×-39))/2×5 =
= (-2 ± sqrt(4 + 780))/10 =
= (-2 ± sqrt(784))/10 = (-2 ± 28)/10
y1 = (-2 + 28)/10 = 26/10 = 2.6
y2 = (-2 - 28)/10 = -30/10 = -3
x1 = 5×2.6 + 2 = 13 + 2 = 15
x2 = 5×-3 + 2 = -15 + 2 = -13

Calculate the volume of liquid that would fill the bowl of each class. Show all your calculations and explain your reasoning.
(no links plz)
Answer:
The volume of liquid that will fill the bowl of the glass is approximately 178.82 cm³
Step-by-step explanation:
The given dimensions of the bowl are;
The shape of the bowl containing the liquid = A cone
The base length of the triangular cross-section of the cone = The diameter of the cone, d = 6 cm
The slant height of the triangular cross-section of the cone = The slant height of the cone, l = 7 cm
Therefore, the height of the cone, h = √(l² - (d/2)²)
∴ h = √(7² - (6/2)²) = 2·√10
The height of the cone, h = 2·√10 cm
The volume of a cone, V = (1/3) × Base area, A × Height, h
V = A × h
The base area of the cone, A = π × (d/2)²
A = π×(6/2 cm)² = 9·π cm²
By plugging in the values
V = A × h
∴ V = 9·π cm² × 2·√10 cm ≈ 178.82 cm³
The volume of the cone = The volume of liquid that will (can) fill the bowl of the glass, V ≈ 178.82 cm³.

Jim is repainting a free-throw key of a basketball court. the free-throw is made by combining a rectangle and a semicircle, as shown below. In order to know how much paint to purchase, Jim will determine the area of the free-throw key. What is the total area, to the nearest whole square foot, of the free-throw key shown in the diagram?
Answer:
285
Step-by-step explanation:
First find the area of the rectangle
A = l*w
A = 19*12 = 228
The find the area of the semicircle
A = 1/2 pi r^2
We know the diameter is 12 so the radius is half the diameter so 1/2 (12) = 6
A = 1/2 (3.14)(6)^2
= 1/2 (3.14) (36)
= 56.52
Add the two areas together
225+56.52
284.52
Rounding to the nearest whole number
285
What is the perimeter of this equilateral triangle?
Choices
4
20
40
60
Answer:
60
Step-by-step explanation:
If it is an equilateral triangle the sides are equal
24-x = 5x
Add x to each side
24-x+x = 5x+x
24 =6x
Divide by 6
24/6 =6x/6
4 =x
Each side is 5x or 5*4 = 20
Add the 3 equal sides
20+20+20 = 60
The perimeter is 60
Answer:
60
Step-by-step explanation:
In this case, to find the perimeter, we need to know the value of at least one side.
Since this triangle is equilateral, [tex]5x=24-x[/tex].
Adding x to both sides results in [tex]6x=24[/tex], and subsequently, [tex]x=4.[/tex]
Now that we know x equals 4, we can plug this into either 5x or 24-x and find out that one of the sides is 20.
Equilateral triangles have three equal sides, so 20 times 3, or 60, is the perimeter. I hope this helped!

Find the measure of arc DF
Answer:
Step-by-step explanation:
Angle E is one-half the measure of the difference between arc CG and arc DF. Mathematically, that looks like this:

44(2) = 160 - DF and
88 = 160 - DF and

[tex]r=\frac{7±3\sqrt{5} }{2}[/tex]
Ignore the A before the ±. It wouldn't let me type it correctly.
Step-by-step explanation:
2r² + 7r - 1 = 3r²
2r² + 7r - 1 - 3r² = 0
- r² + 7r - 1 = 0
- (r² - 7r + 1) = 0
- (r² - 7r + 1) ÷ - 1 = 0 ÷ - 1
r² - 7r + 1 = 0
[tex]r=\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex]
Ignore the A before the ±. It wouldn't let me type it correctly.
r² - 7r + 1 = 0
a = 1
b = - 7
c = 1
[tex]r=\frac{-(-7)±\sqrt{(-7)^{2}-4((1)(1)) } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{49-4((1)(1)) } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{49-4 } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{45 } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{(3)(3)(5) } }{2(1)}[/tex]
[tex]r=\frac{7±(\sqrt{3 } )(\sqrt{3})(\sqrt{5}) }{2(1)}[/tex]
[tex]r=\frac{7±3\sqrt{5} }{2}[/tex]
Two separate equations
[tex]r=\frac{7+3\sqrt{5} }{2}[/tex]
[tex]r=\frac{7-3\sqrt{5} }{2}[/tex]

Answer:
rad66/11
Step-by-step explanation:
Using Sohcahtoa, you can find that the tangent is the opposite side over the adjacent side. This means that the tangent of angle X is 2rad6/2rad11. You then simplify it to rad6/rad11. Preferably, a radical shouldn't be in the denominator. You can muliply both sides by rad 11 to balance the equation into rad66/11.

Last month Maria hiked a total of 90 miles on two trails: a 5-mile mountain trail and a 10-mile canal trail. Let x represent the number of times Maria hiked the mountain trail, and let y represent the number of times Maria hiked the canal trail.
Which equation can be used to find the number of times Maria hiked each trail?
Answer:
5x+10y=90
Step-by-step explanation:
The equation that can be used to find the number of times Maria hiked each trail is 5x + 10y = 90.
How to depict the equation?From the information, Maria hiked a total of 90 miles on two trails: a 5-mile mountain trail and a 10-mile canal trail.
x represent the number of times Maria hiked the mountain trail.
y represent the number of times Maria hiked the canal trail.
The equation will be:
= (5 × x) + (10 × y) = 90
= 5x + 10y = 90
The equation is 5x + 10y = 90.

4,284 passengers traveling by the intercity bus every day, the intercity bus operates 6 hours every day, find the number of passengers every hour
Please do it as quick as possible
Answer:
714
Step-by-step explanation:
So lets go over what we know.
The bus only goes for 6 hours each day.
So lets just think of a full day as 6 hours.
Each day(6 hours), 4284 passangers ride the bus.
To find passangers per hour, we must divide the total passangers by the total hours.
This is 4284(total passangers) divided by 6(total hours):
4284/6
=
714
So each hour, there are 714 passangers.
Hope this helps!

Find m∠ABD and m∠CBD given m∠ABC = 111∘.
Answer:
m∠ABD = 88º
m∠CBD = 23º
Step-by-step explanation:
(-10x + 58) + (6x + 41) = 111
Combine like terms
-4x + 99 = 111
Subtract 99 from both sides
-4x = 12
Divide both sides by -4
x = -3
------------------------
m∠ABD = -10x + 58
m∠ABD = -10(-3) + 58
m∠ABD = = 30 + 58
m∠ABD = 88º
m∠CBD = 6x + 41
m∠CBD = 6(-3) + 41
m∠CBD = -18 + 41
m∠CBD = 23º
Answer:
88, 23
Step-by-step explanation:
<ABD + <DBC = <ABC
(-10x + 58) + (6x + 41) = 111
-10x + 58 + 6x + 41 = 111
99 - 4x = 111
-4x = 111-99
-4x = 12
x = 12/-4
x = -3
m∠ABD = -10x + 58
m∠ABD = -10(-3) + 58
m∠ABD = = 30 + 58
m∠ABD = 88º
<DBC = 6x + 41 = 6*-3 + 41 = -18 + 41 = 23
