The circumference of the circle is given as 2[tex] \pi [/tex]r where [tex] \pi [/tex] is a constant whose value is equal to 22/7 and r is the radius of the circle
From the given problem, we have the circumference =37.7
2[tex] \pi [/tex]r = 37.7
2*22/7*r = 37.7
r = 37.7*7/(22*2)
r = 263.9/44
r = 5.99
r = 6cm
Radius = 6 centimeters (Rounded to nearest whole number)

ΔABC and ΔXYZ are similar triangles. If BA = x + 9, AC = x + 7, YX = x + 5, and XZ = x + 4, find the value of x.
Answers
Solution:
we are given that ΔABC and ΔXYZ are similar triangles.
As we know , when two triangles are similar then the ratios of their corrsponding sides are equal.
Here we have
BA = x + 9, AC = x + 7, YX = x + 5, and XZ = x + 4
So we can write
[tex] \frac{x+9}{x+5}= \frac{x+7}{x+4}\\ \\ (x+9)(x+4)=(x+7)(x+5)\\ \\ x^2+13x+36=x^2+12x+35\\ \\ 13x-12x=35-36\\ \\ x=-1\\ \\ [/tex]
Hence then value of x=-1.

Use absolute value to express the distance between −13 and 17 on the number line
Answers
Answer:
Step-by-step explanation:
Distance between two points a and b using the absolute value is given by
|b-a|.
Here we have a=-13
and b =17
so
Distance = | 17- (-13) |
Distance = |17 +13 |
Distance = | 30 |
Distance = 30 units
In absolute value, the distance is written as |30|
The given points:
[tex](x_1, x_2) = (-13, 17)[/tex]
To find:
the distance between -13 and 17The distance between the two points on a number line is calculated as;
[tex]Distance = \sqrt{(x_2-x_1)^2} \\\\Distance = \sqrt{(17--13)^2}\\\\Distance = \sqrt{(30)^2} \\\\Distance = + /- \ \ 30[/tex]
In absolute value, the distance is written as;
Distance = |30|

Step-by-step explanation:

The Equation have No solution is 4(x + 3) + 2x = 6(x + 2).
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
First, 4(x + 3) + 2x = 6(x + 2)
4x + 12 + 2x = 6x + 12
6x + 12 = 6x+ 12
0 = 0
Thus, the equation have No solution.
Second, 5 + 2(3 + 2x) = x + 3(x + 1)
5 + 6 + 6x = x + 3x + 1
6x+ 11 = 4x+ 1
2x = -10
x= -5
Thus, the equation have one solution.
Third, 5(x + 3) + x = 4(x + 3) + 3
5x+ 15 +x = 4x + 12 + 3
6x +15 = 4x + 15
2x = 0
x= 0
Thus, the equation have one solution.

Hope this helps! :)
The value of r that makes the expression 7r less than 7 is 4/5, as multiplying 7 by 4/5 results in 5.6, which is less than 7.
The question asks which value of r makes the expression 7r equal a number less than 7, given the choices of 4/4, 4/3, 4/5, or 4/1. To find the solution, we simply multiply 7 by each fraction option and see which results in a number less than 7.
For 4/4 (or 1): 7 * 1 = 7For 4/3: 7 * (4/3) > 7For 4/5: 7 * (4/5) = 5.6, which is less than 7For 4/1 (or 4): 7 * 4 > 7Thus, the value of r that makes the expression 7r result in a number less than 7 is 4/5.
a trapezoid with an area of 166.75 in has bases that measure 21 in and 8 in find the height of the trapezoid
Answers
The area of trapezoid is calculated as -
Area of trapezoid = [tex] \frac{a + b}{2} X height [/tex]
Here, a = base 1
b = base 2
Height is the height of trapezoid.
It is given that,
Area of trapezoid = 166.75 in
Base 1, a = 21 in
Base 2, b = 8 in
Area of trapezoid = [tex] \frac{a + b}{2} X height [/tex]
166.75 in = [tex] \frac{21 in + 8 in}{2} X height [/tex]
Height = [tex] \frac{ 166.75 in}{14.5}
Height = 11.5 in
Thus, height of trapezoid = 11.5 In

1. You must apply the formula for calculate the area of a circle, which is:
A=πr^2
Where A is the area of the circle and r is the radius of the circle.
2. You have that the diameter is 6 feet, then the radius is:
r=D/2
r=3 feet
3. When you apply the formula shown above, you obtain:
A=9π feet^2
A=28.27 feet^2
The answer is: 28.27 feet^2

kendra flips a coin 3 times what is the probability that she flips tails all 3 times
Answers
To find the probability of flipping tails all three times, we need to consider that each flip of a fair coin has a probability of 0.5 of landing on tails.
Since the coin flips are independent events (the outcome of one flip doesn't affect the outcome of another flip), we can simply multiply the probability of each individual flip.
So, the probability of flipping tails three times in a row is:
P(Tails, Tails, Tails) = P(Tails) × P(Tails) × P(Tails)
P(Tails, Tails, Tails) = 0.5 × 0.5 × 0.5
P(Tails, Tails, Tails) = 0.5³
P(Tails, Tails, Tails) = 0.125
So, the probability that Kendra flips tails all three times is 0.125 or18.
The probability of flipping tails on a fair coin is 0.5 (or 1/2) since there are two equally likely outcomes, heads or tails. When flipping a coin three times, each flip is independent, meaning the outcome of one flip doesn't affect the outcome of another.
To find the probability of flipping tails all three times, we multiply the probability of each individual flip.
So, 0.5 (tails on the first flip) times 0.5 (tails on the second flip) times 0.5 (tails on the third flip) equals 0.5³ = 0.125.
Therefore, the probability that Kendra flips tails all three times is 0.125 or 1/8.

the ratio of boy to girls in 8th grade is 5 to 3 ,how many girls are there in 8th grade if there are 80 students in 8th grade
Answers
------- = --- Note that 5+3 = 8. Thus, (5/8) of the 80 students are boys and
girls 3 (3/8) of the 80 students are girls. This comes out to 30 girls (and 50 boys) Note that 30+50=80 (students)
. Thus, the number of girls =30.
Let's denote the number of boys as 5x and the number of girls as 3x. According to the problem, the total number of students is the sum of both boys and girls:
5x + 3x = 80
Combining the terms, we get:
8x = 80
Now, solving for x:
x = 80 / 8
x = 10
Now that we know the value of x, we can find the number of girls:
Number of girls = 3x = 3 * 10 = 30
Therefore, there are 30 girls in the 8th grade.
