Answer: 50
Step-by-step explanation: First of all, you need to establish your rate of acceptance. This would be 10 out of 48 or 10/48. Next, you need to simplify this to 5/24. Okay now this is epic. Now you need to convert 5/24 to x/240. Simple. Just multiply both sides by ten in 5/24 and you get your answer of 50. Very cool.
Final answer:
Michelle can expect approximately 50 students to join her book club based on the proportion of surveyed students who expressed interest.
Explanation:
Michelle surveyed 48 students, and 10 said they would join the book club. To estimate how many out of the total 240 students might join, we use proportions. The first step is to set up a proportion with the numbers Michelle has provided and then solve for the unknown:
Number of students surveyed who would join / Total students surveyed = Expected number who would join / Total students in grade
10 / 48 = x / 240
To find x, multiply both sides by 240:
240 * (10 / 48) = x
Then solve for x:
x = 50
Thus, Michelle could expect about 50 students to join the book club.

The diameter of your bicycle wheel is 34 inches. What is it’s radius
The diameter of a circle (or in this case a bicycle wheel) is how long it is from one side of the circle striaght across to the other side. The radius is half the diameter. So if the diameter is 34, then the radius would be 17.
17 inches
Diameter = 2 * radius
So you can rewrite that as
Radius = diameter / 2
34/2=17

Answer:
Answer:
4(x-3)(x+6)
Step-by-step explanation:
We factor out the 4 first since all numbers are divisible by 4. That leaves us with x^2+3x-18.
Then we factor this to get (x-3)(x+6).
So the factored form of the equation is 4(x-3)(x+6)
Step-by-step explanation:
The factors of the equation 4x²+12x -72 will be 4(x-3)(x+6).
What is a quadratic equation?A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Factor out the 4 first since all numbers are divisible by 4. That leaves us with x² +3x -18.
4( x² +3x -18 ) = 4 ( x² + 6x - 3x -18 )
= 4 ( x(x+6) -3 (x + 6)
= 4 ( x + 6 ) ( x - 3 )
Hence, the factors are 4 ( x + 6 ) ( x - 3 ).

if ||M and M6 = 4X - 15 and m7 = x + 30 then m 6 =
Answer:
15Step-by-step explanation:
∠6 and ∠7 are Alternate Interior Angles.
The lines l and m are parallel, therefore ∠6 and ∠7 are congruent.
m∠6 = m∠7 → 4x - 15 = x + 30 add 15 to both sides
4x = x + 45 subract x from both sides
3x = 45 divide both sides by 3
x = 15
Answer:
[tex]\angle 6 =45^{\circ}[/tex]
Step-by-step explanation:
We are given that l || m
[tex]\angle 6 = 4x-15[/tex]
[tex]\angle 7 = x+30[/tex]
Since l || m
So, [tex]\angle 6 = \angle 7[/tex] (Alternate interior angles are equal )
So, [tex]4x-15 = x+30[/tex]
[tex]3x= 45[/tex]
[tex]x= 15[/tex]
[tex]\angle 6 = 4x-15=4(15)-15 = 45^{\circ}[/tex]
So, [tex]\angle 6 =45^{\circ}[/tex]

A (8, –1) and B (–4, 17)
Answer:
[tex]\large\boxed{y=-\dfrac{3}{2}x+11}[/tex]
Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{17-(-1)}{-4-8}=\dfrac{18}{-12}=-\dfrac{3}{2}[/tex]
The equation of a line:
[tex]y=-\dfrac{3}{2}x+b[/tex]
Put the coordinates of the point A(8, -1) to the equation of a line:
[tex]-1=-\dfrac{3}{2}(8)+b[/tex]
[tex]-1=-3(4)+b[/tex]
[tex]-1=-12+b[/tex] add 12 to both sides

a right triangle has a leg of 11cm and a hypotenuse of 17cm what is the length of the other leg round to the nearest tenth
Answer: [tex]2\sqrt{42}cm[/tex] ≈12.96 cm
Step-by-step explanation:
To solve this exercise you must apply the Pythagorean Theorem, which is the shown below:
[tex]a^2=b^2+c^2[/tex]
Where a is the hypotenuse and b and c are the other legs.
You know that the triangle has a leg of 11 cm and the hypotenuse is 17 cm. Therefore, you can substitute values and solve for the other leg.
Then you obtain:
[tex](17cm)^2=b^2+(11cm)^2\\b=\sqrt{(17cm)^2-(11cm)^2}\\b=2\sqrt{42}cm[/tex]
b≈12.96 cm

I don't know what else to add, so if you have any additional problems, please list them under this question. I will see your comment.
A sample calculation would be
y = - abs(-x)
Let x = - 2
y = - abs(-2)
The absolute command changes - 2 to + 2
y = - abs(2)
y = - 2 because of the minus sign in front of the absolute value command.
So the point is (-2,-2)

7 1/2 divided by 1 9/10 simplified
Answer:
[tex]\large\boxed{3\dfrac{18}{19}}[/tex]
Step-by-step explanation:
[tex]\text{First step:}\\\text{Convert the mixed number to the improper fractions:}\\\\7\dfrac{1}{2}=\dfrac{(7)(2)+1}{2}=\dfrac{15}{2}\\\\1\dfrac{9}{10}=\dfrac{(1)(10)+9}{10}=\dfrac{19}{10}\\\\7\dfrac{1}{2}:1\dfrac{9}{10}=\dfrac{15}{2}:\dfrac{19}{10}\\\\\text{Dividing by a fraction is the same as multiplying by the inverse of a fraction}\\\\=\dfrac{15}{2}\cdot\dfrac{10}{19}=\dfrac{15}{2\!\!\!\!\diagup_1}\cdot\dfrac{10\!\!\!\!\diagup^5}{19}=\dfrac{15}{1}\cdot\dfrac{5}{19}=\dfrac{75}{19}=3\dfrac{18}{19}[/tex]
First, convert the mixed fractions into improper fractions. Then, turn the division problem into a multiplication problem by utilizing the concept of reciprocal. This gives us 75/19, or about 3.95 in decimal.
We first need to convert the mixed fractions into improper fractions. To do this, we multiply the whole number by the denominator of the fractional part and then add the numerator, placing this sum over the original denominator. This makes 7 1/2 into 15/2 and 1 9/10 into 19/10. The division problem 7 1/2 divided by 1 9/10 simplifies to 15/2 divided by 19/10.
Next, we remember that dividing by a fraction is the same as multiplying by its reciprocal. The reciprocal of a fraction is obtained by swapping the numerator and denominator. So, we change our division problem into a multiplication problem, transforming 15/2 divided by 19/10 into 15/2 * 10/19.
After multiplying these fractions, we get 150/38, which simplifies to 75/19, which is approximately 3.95 when converted to decimal.
