Answer:
122°
Step-by-step explanation:
10a + 2° + 5a - 2° = 180° [ being linear pair ]
15a = 180°
a = 180° / 15
a =12°
Now
<XYQ = 10a + 2° = 10 * 12° + 2° = 120° + 2° = 122°

Colton gave out a survey to some students in his school about their favorite color. 470 of those surveyed said their favorite color was blue. If 94% of the students surveyed said their favorite color was blue, how many students were surveyed in total?

Step-by-step explanation:
Convert percent to decimal:

The function f(x)f(x) is a quadratic function and the zeros of f(x)f(x) are 11 and 55. The y-intercept of f(x)f(x) is 2020. Write the equation of the quadratic polynomial in standard form.
Answer: [tex]4x^2 -24x+20[/tex]
Step-by-step explanation:
If p and q are zeroes of f(x), then f(x) = k (x-p)(x-q) , where k is a constant.
Given: The function f(x)f(x) is a quadratic function and the zeros of f(x)f(x) are 1 and 5.
f(x) = k (x-1)(x-5)
y-intercept = Value of function at x=0
So, y-intercept = k (0-1)(0-5)= 5k
Since, y-intercept of f(x) = 20
so, 5k = 20
⇒ k= 4
Quadratic polynomial [tex]= 4(x-1)(x-5)[/tex]
[tex]=4(x^2-6x+5)\\\\= 4x^2 -24x+20[/tex]
Hence, the equation of the quadratic polynomial in standard form =[tex]4x^2 -24x+20[/tex]

Amelia's Reliable Fencing Co. prices fences based on the amount of fencing installed plus a fixed amount of $200. The
company charges S4 per foot of standard fencing. Which of the following scenarios is correct?
It costs $1040 to enclose a 90' by 40' rectangular area.
It costs $560 to enclose a 50' by 40' rectangular area.
ОООО
It costs $2600 to enclose a 10' by 60' rectangular area.
It costs $1480 to enclose an 80' by 80' rectangular area.
Answer:
It costs $560 to enclose a 50' by 40' rectangular area.
Step-by-step explanation:
50 + 40 = 90
90 x 4 = 360 because of the $4 per foot
360 + 200 = 560, you add 200 because of the flat rate charge.
Brainly annie has 2 bags of apples and 5 single apples eva has 1 bag of apples and 11 single apples they have the same amount of apples how many apples so they have in total
Answer:
34 apples
Step-by-step explanation:
To answer: try setting up each of the equations for Annie and Eva.
Annie: 2(bag) + 5
Eva: 1(bag) + 11
Those two equations equal each other. So set that up:
2(bag) + 5 = 1(bag) + 11
Now solve for the size of the bag.
2(bag) - 1(bag) = 11 - 5
1(bag) = 6 apples
Now substitute 6 back into either equation to determine number of apples.
Annie: 2(6) + 5 = 12+5=17
They each have 17, so there are 34 apples in total.
1< a+7/-2
The is supposed to be written like a fraction so think
A+7
____

Answer:
We get the value of a: [tex]\mathbf{a<-9}[/tex]
Step-by-step explanation:
We have to solve the inequality [tex]1<\frac{a+7}{-2}[/tex]
So, solving the inequality and finding value of a
First step is to switch both sides and for doing so, the inequality will be reversed
[tex]\frac{a+7}{-2}>1[/tex]
Multiply both sides by -2, as we are multiplying by a negative number, the inequality will be reversed
[tex]\frac{a+7}{-2}\times -2<1\times -2[/tex]
[tex]a+7 < -2[/tex]
Now, subtracting both sides by 7, to find value of a
[tex]a+7-7<-2-7\\a<-9[/tex]
We get the value of a: [tex]\mathbf{a<-9}[/tex]

A regular octagonal pyramid. Each side of the base is 6 cm long. it has a height of 10cm. Find the surface area of the pyramid
9514 1404 393
Answer:
470.16 cm²
Step-by-step explanation:
The apothem of the base is used for two purposes: to find the area of the base, and to find the slant height of each face.
The apothem of the base for side length s is ...
s/2 = a·tan(π/8)
a = s/(2·tan(π/8)) ≈ 7.24 cm
The slant height of a triangular face is found using the Pythagorean theorem. The apothem of the base and the height are legs of the right triangle whose hypotenuse is the slant height. For slant height x, we have ...
x² = 10² + a² = 100 +52.46
x ≈ √152.46 ≈ 12.35
__
The area of the 8 triangular faces will be ...
A = 1/2Px . . . . where P is the perimeter of the pyramid
The area of the base will be ...
A = 1/2Pa
So, the total surface area is ...
A = 1/2P(a + x) = (1/2)(8)(6 cm)(7.24 +12.35 cm) ≈ 470.16 cm²
The answer is 470.16 cm²

Answer:
Student B
Step-by-step explanation:
Student B's wages increase by 6 each time, but Students A, C, and D do not steadily increase. The steady increase of 6 for Student B is what makes their wages proportional.

Justin has a roll of tape 549 centimeters long. he cuts the tape into pieces that are 9 centimeters long. How many 9 centmeter pieces can Justin cut from his roll of tape?
Answer: 61
Step-by-step explanation: My Teacher told me is Right
The number of the 9-centimeter long tape will be 61. The correct option is C.
What is division?Discovering the maximum number of equal pieces that can be made by splitting an integer into equal parts.
One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division. The other operations are multiplication, addition, and subtraction.
Given that Justin has a roll of tape 549 centimeters long. he cuts the tape into pieces that are 9 centimeters long.
The number of 9 centimeters tapes will be calculated as below:-
Number = 549 / 9
Number = 61
Therefore, the number of the 9-centimeter long tape will be 61. The correct option is C.

Sinister Stan stole 3 3/4 oz of slime from Messy Molly, but his evil plans require 6 3/8 oz of slime. He stole another 2 3/5 oz of slime from Rude Ralph. How much more slime does Sinister Stan need for his evil plan?
Answer: 1/40
Step-by-step explanation:
Since we are told that Sinister Stan stole 3 3/4 oz of slime from Messy Molly and stole another 2 3/5 oz of slime from Rude Ralph. The total oz of slime stole would be:
= 3 3/4 + 2 3/5
= 3 15/20 + 2 12/20
= 5 27/20
= 6 7/20
We are told that his evil plans require 6 3/8 oz of slime, the amount needed for Sinister Stan for his evil plan would be:
= 6 3/8 - 6 7/20
= 6 30/80 - 6 28/80
= 2/80
= 1/40
