Answer:
r ≈ 4
Step-by-step explanation:
circle = 360 degrees
360 / 90 = 4
let's call the area of triangle XYZ + the shaded area portion A
because ∠XYZ = 90°, and 360 / 90 = 4, A = 1/4th of the area
total area of circle = πr²
XY = YZ = radius
thus, as ∠XYZ = 90° and two sides are the same, this forms a 45-45-90 triangle, with base YZ and height XY (base/height are interchangeable here)
thus, area of triangle XYZ = r*r/2 = r²/2
area A = r²/2 + 4.64
4 * A = total area of circle
4(r²/2+4.64) = πr²
2r²+18.56 = πr²
subtract 2r² from both sides to put all the variables on one side
(π-2)r² = 18.56
divide both sides by (π-2) to isolate r²
18.56/(π-2) = r² ≈ 16.258
r ≈ 4.032 ≈ 4

Answers
Answer:
Answer Choice A (8, eight)
Step-by-step explanation:
To begin, add all of the marbles together. When finished, the answer should be 20. Because the variable 20 equals 100, you divide 4 by 100. You will get 0.04 as a result. This multiplied by 20 equals 8. Finally, the answer is A.

The length GD, GE, and GF are the radius of the circle. Then GD = GE = GF is true. Thus, option A is correct.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
The G is the intersection of the bisector lines. So, the G represents the center of the incircle.
The incircle will touch all three sides of the triangle. And the distance between the center of the circle to the sides of the triangle will be known as the radius and tangent to the circle.
Then we can write a condition for a circle. Then we have
GD = GE = GF = Radius
The length GD, GE, and GF are the radius of the circle. Then GD = GE = GF is true. Thus, option A is correct.

5. a) Among 72 students, 24 are selected to participate in music only, 26 are selected to participate in dance only and none of them participated in both activities. The rest of the students are selected in other activities. (i) How many students are participating in other than music or dance?
Answers
Answer
The students participating in other than music or dance = 22
Step by step explanation
Total number of students = 72
No. of students participating in dance = 26 (let them be 'a')
No. of students participating in music = 24 (let them be 'b')
No. of students participating in othe na than dance or music = 'c'
72 = a+b+c
= 26+24+c
= 50 + c
c (no. of students participating in other activities)

Tyrell has a bankruptcy on his credit report and therefore pays higher interest rates on his current loans. he calculates that the extra money he pays in additional interest each year, if invested at the rate of 2.5% for one year, could earn him simple interest totaling $300. how much does tyrell pay in additional interest each month? a. $90 b. $100 c. $1,000 d. $12,000 please select the best answer from the choices provided. a b c d
Answers
Based on the simple interest amount he could be making, and the rate of investment, Tyrell's additional interest per month is $1,000.
How much is Tyrell paying in additional interest?Assuming the additional interest that Tyrell is paying is x, the following formula can be used:
300 = (x × 2.5%) x 12 months
Solving gives:
300 = 0.025x × 12
0.025x = 300/12
x = 25 / 0.025

6×$16.98=$101.88=cost of basketballs
6×$13.79=$82.74=cost of soccer balls
cost of basketballs + cost of soccer balls = total cost
$101.88+$82.74=$184.62

What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Given the standard deck has 26 black cards while the total number of cards is 52. Therefore, the probability of two cards being black without replacement is,
Probability = (Probability of the first card is black) × (Probability of the second card being black)
Probability = (26/52) × (25/51)
Probability = 0.245 = 24.5%
Hence, the probability of two cards being black without replacement is 24.5%.

[tex]\blue{\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}[/tex]
First of all, parallel lines have the exact same slope.
So we know the slope of the line:- -5.
(enter -5, It's the number that belongs in the green box)
How about the y-intercept?
Well, since we're given the slope and a point that the line intersects, we can write the line's equation in point-slope form:-
y-y1=m(x-x1)
y-(-3)=-5(x-(-3)
y+3=-5(x+3)
y+3=-5x-15
y=-5x-18

The equation of line which is parallel to y= -5x - 9 is y=-5x-18.
What is equation of line?The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis.
Given:
y= -5x - 9 passes the point (-3, -3)
As, the slope of parallel lines are
m1 = m2 = -5
Now, if the point (-3, -3) intersects the line then equation in point-slope form is
y-y1=m(x-x1)
y-(-3)=-5(x-(-3)
y+3=-5(x+3)
y+3=-5x-15
y=-5x-18
Hence, the equation of line is y=-5x-18

A) 3/8
B) 2/3
C) 5/8
D) 1/2
Answers
Answer:
Step-by-step explanation:
My approach was to draw out the probabilities, since we have 3 children, and we are looking for 2 boys and 1 girl, the probabilities can be Boy-Boy-Girl, Boy-Girl-Boy, and Girl-Boy-Boy. So a 2/3 chance if you think about it, your answer 2/3 can't be correct. If we assume that boys and girls are born with equal probability, then the probability to have two girls (and one boy) should be the same as the probability to have two boys and one girl. So you would have two cases with probability 2/3, giving an impossible 4/3 probability for both cases. Also, your list "Boy-Boy-Girl, Boy-Girl-Boy, and Girl-Boy-Boy" seems strange. All of those are 2 boys and 1 girl, so based on that list, you should get a 100 percent chance. But what about Boy-Girl-Girl, or Girl-Girl-Girl? You get 2/3 if you assume that adjacencies in the (ordered) list are important, i.e., "2 boys and a girl" means that the girl was not born between the boys.
