Answer:
678.32 feet
Step-by-step explanation:
Circumference=2π(radius)=2·π·50≈314.15927
314.15927·2=628.31854
628.31854+50=678.31854
Answer:
678 ft (nearest foot)
Step-by-step explanation:
The distance from the center of a circle its edge is its radius.
Given that the distance from the center of a circular tent to the tent’s edge is 50 ft then:
⇒ radius (r) = 50
The edge of a circle is its circumference
Circumference of a circle = [tex]2\pi r[/tex] (where r is the radius)
Therefore, the circumference of the tent is:
[tex]\implies 2 \cdot \pi \cdot 50=100\pi[/tex] ft
If Kelly walked around the edge of the tent twice, then walked straight to the center:
⇒ total distance walked = 2 × circumference + radius
= 2 × [tex]100\pi[/tex] + 50
= 678.3185307...
= 678 ft (nearest foot)
The students in Ms. Baca's art class were mixing yellow and blue paint. She told them that two mixtures will be the same shade if the blue and yellow paint are in the same ratio. How many different shades of paint did the students make?
Answer:
Two shades will be prepared.
Step-by-step explanation:
Ms Baca told the students that when two colors yellow and blue are mixed in the same ratio same shade is prepares.
From the table attached,
If A is a mixture of 1 part yellow and 2 parts of blue color,
Ratio of the colors = 1 : 2
If B is a mixture of 2 parts yellow and 3 parts of blue color,
Ratio of the colors = 2 : 3
If C is the mixture of 3 parts yellow and 6 parts of blue color,
Ratio of the colors = 3 : 6 = 1 : 2
If D is a mixture of 4 parts yellow and 6 parts of blue color,
Ratio of the colors = 4 : 6 = 2 : 3
If E is a mixture of 6 parts yellow and 9 parts of blue color,
Ratio of the colors = 6 : 9 = 2 : 3
Therefore, mixtures A, C will create the same shade while mixtures B, D, E will be of same shade but different from A and C.
Two shades of the paints will be made by the students.
If 10 percent of x is 20 what is 23 percent of x
Answer: 46%
Step-by-step explanation:

On a piece of paper, use a protractor to construct a triangle with angle measures of 60° and 80°. I Which statements about this triangle are true? Select all correct answers.
Answer:
Option A
Option C
Option D
Step-by-step explanation:
Triangle attached in image~
A) It is an acute triangle (Yes)
Before we put reasonings why this is true, let's find the missing angle in the triangle.
⇒ 60 + 80 + x = 180°⇒ 140 + x = 180°⇒ x = 180 - 140⇒ x = 40°This triangle is an acute triangle because all angles in the triangle are acute, as 80°, 60°, 40° are acute angles.
B) Two sides have the same length (No)
Two sides can only be the same if two angles are equivalent. Since all angles are different, two sides cannot have the same length.
C) All sides have different lengths (Yes)
Since all angles are unalike, the triangle has different side lengths.
D) The third angle measures 40° (Yes)
⇒ 60 + 80 + x = 180°⇒ 140 + x = 180°⇒ x = 180 - 140⇒ x = 40°Answer:
A

Paul can paint 119 doors in 8 hours, while Scott can paint 54 doors in 4 hours. Who can paint the doors faster, Paul or Scott?
A. Paul
B. Scott
Answer:
See below
Step-by-step explanation:
You need to find the unit rate, which is found by dividing the number of doors, in this case, by time.
119/8=14.875
54/4=13.5
Paul can paint doors faster.

A sports analyst determines that the number of points scored in a basketball game is related to the number of shots taken during the game. The least-squares regression line is y = 5. 0 + 1. 2x, where y is the predicted number of points scored and x is the number of shots taken. In one game, a team takes 50 shots and the residual is –10. How many points were scored by this team in this game?
45
55
65
75
Answer:
65
Step-by-step explanation:
y= 5.0 + 1.2x
when x = 50
y = 5.0 + 1.2 x 50
= 5.0 + 60
= 65
The value of y is 65 when x = 50, or the number of points the team was scored was 65.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A sports analyst determines that the number of points scored in a basketball game is related to the number of shots taken during the game.
y= 5.0 + 1.2x
Plug x = 50
y = 5.0 + 1.2 x 50
= 5.0 + 60
= 65
Thus, the value of y is 65 when x = 50, or the number of points the team was scored was 65.

x = c ( c is the x- coordinate of the vertex )
the vertex is at (1, 0 ) with x- coordinate 1 , then
equation of axis of symmetry is x = 1
No receives a $5 discount each month on his cell phone bill because he signed up for autoplay from his bank account over the last eight months nor has pay a total of $284 for his cell phone bill what would Noah be charged for his cell phone bill each month if he stopped using autoplay?
Answer:
$36Step-by-step explanation:
Normally Noah is expected to pay an amount without a discount.
let this amount be x
so the amount paid monthly after the discount is removed is (x-5)
Noah paid this amount for 8 months
(x-5)*8=248
solving for x we will get the amount that Noah is expected to be charged when he stopped using the autoplay
(x-5)*8=248
8x-40=248
8x=248+40
8x=288
divide both sides by 8 we have
x=288/8
x=$36

Find the value of x. (2x +4)° 2x-9)°
Answer: x=3
Step-by-step explanation: 2x +4)° 2x-9)°= 4x 2 +8x−9=3
Pull out like factors :
2x + 4 = 2 • (x + 2) (4 • (x + 2) • x) - 9
4x • (x + 2) - 9
Factoring 4x2+8x-9
The first term is, 4x2 its coefficient is 4 .
The middle term is, +8x its coefficient is 8 .
The last term, "the constant", is -9
Step-1 : Multiply the coefficient of the first term by the constant 4 • -9 = -36
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is 8 .
-36 + 1 = -35
-18 + 2 = -16
-12 + 3 = -9
-9 + 4 = -5
-6 + 6 = 0
-4 + 9 = 5
-3 + 12 = 9
-2 + 18 = 16
-1 + 36 = 35

The value of x for the given triangle is 37°.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
The sum of all interior angles of a triangle is 180°.
So,
x + 2x +4 + 2x-9 = 180°
5x - 5 = 180°
x = 37°
Hence "The value of x for the given triangle is 37°".

degrees
AC
4x+29
12x+55
B
Answer:
x = 6
Step-by-step explanation:
The 2 angles given are same- side interior angles and are supplementary, thus
4x + 29 + 12x + 55 = 180, that is
16x + 84 = 180 ( subtract 84 from both sides )
16x = 96 ( divide both sides by 16 )
