How can Brady use fraction strips to show that 3 4 and 7 8 are NOT equivalent?
To demonstrate that 3/4 and 7/8 are not equivalent, Brady can use fraction strips to visually compare the colored portions of the strips, which will clearly show that 7/8 is greater than 3/4 as it has more colored sections.
Explanation:To show that 3/4 and 7/8 are not equivalent using fraction strips, Brady can follow these steps:
Take one strip and divide it into four equal parts to represent the fraction 3/4. Color three of these parts.Take another strip, divide it into eight equal parts to represent the fraction 7/8, and color seven of these parts.Compare the two colored strips side by side.Brady will observe that the strip representing 7/8 has more colored sections than the strip representing 3/4, even though the strips are the same length. This visual comparison confirms that 3/4 is less than 7/8, thus they are not equivalent fractions. The fraction 7/8 is only one-eighth away from being a whole, whereas 3/4 is one-fourth away.
Roderick wants to draw a circle for which the numerical value of the circumference is greater than the value of the area. Which lengths could he use for the radius? Check all that apply.
Answer:
The length of the radius must be less than [tex]2[/tex]
[tex]\frac{1}{2},1,1.5[/tex]
Step-by-step explanation:
we know that
The circumference of a circle is equal to
[tex]C=2\pi r[/tex]
The area of a circle is equal to
[tex]A=\pi r^{2}[/tex]
where r is the radius of the circle
In this problem we have that
[tex]C > A[/tex]
Substitute
[tex]2\pi r > \pi r^{2}[/tex]
Simplify
[tex]2r > r^{2}[/tex]
[tex]2> r[/tex] ------> rewrite
[tex] r< 2\ units [/tex]
The length of the radius must be less than [tex]2[/tex]
the answer is
[tex]\frac{1}{2},1,1.5[/tex]
Roderick select the length of radius, for keeping the value of circumference of the circle greater than the value of its area, should be 1/2,1 and 1.5. Thus the option A, B and C is the correct option.
What is circumference and area of the circle?Circumference of the circle is the length of its boundary. It can given as,
[tex]P=2\pi r[/tex]
The area of the circle is the space occupied by it. It can be given as,
[tex]A=\pi r^2[/tex]
Given information-
Roderick wants to draw a circle.
The circumference of the circle must be greater than the area of the circle.
The circumference of the circle having radius equal to [tex]r[/tex] units can be given as,
[tex]P=2\pi r[/tex]
The area of the circle having radius equal to [tex]r[/tex] units can be given as,
[tex]A=\pi r^2[/tex]
Now as Roderick wants to draw a circle in which, the circumference of the circle must be greater than the area of the circle. Thus,
[tex]P>A[/tex]
Put the values as,
[tex]2\pi r>\pi r^2\\2r>r^2\\2>r[/tex]
Thus the value of the radius of Roderick circle must be less than the number 2.
Number 1/2 , 1, and 1.5 is less than the number two.
Thus, Roderick select the length of radius, for keeping the value of circumference of the circle greater than the value of its area, should be 1/2,1 and 1.5. Thus the option A, B and C is the correct option.

Step-by-step explanation:
To solve for x we need to cross multiply it
We have = sign in between the fractions so we cross multiply it
9*x = 2* 8
9x = 16
Now we divide by 9 on both sides
so x= 1.7777777778
When we round to two decimal places then
x= 1.78

In a homicide case 33 different witnesses picked the same man from a line up. the line up contained 5 men. if the identifications were made by random guesses, find the probability that all 33 witnesses would pick the same person. round to seven decimal places.
Final answer:
The probability that Nancy is a robber given Bob's identification is around 33.2%, considering Bob's accuracy and the base rate of robbers in the population.
Explanation:
Probability Calculation:
To find the probability that Nancy is a robber given Bob's identification, we use Bayes' Theorem. Given that Bob is 99% accurate in identifying suspects, the calculation reveals that the probability that Nancy is a robber is around 33.2%.
Base Rate Fallacy: It is crucial to consider the base rate of robbers in the population to avoid common statistical errors in interpreting the probability of an event.

one face of a cube an area of 49 square centimeters. what is the volume of the cube
Need quick help please?! Using the Angle Bisector Theorem solve for x.
Show all work.
Answer:
[tex]x=6[/tex]
Step-by-step explanation:
We have been given a triangle and we are asked to solve for x using angle bisector theorem.
Angle bisector theorem states that if a ray bisects an angle of a triangle, then it divides the opposite side of triangle into segments that are proportional to the other two sides.
Using angle bisector theorem we can set an equation as:
[tex]\frac{4x+1}{5}=\frac{15}{3}[/tex]
Let us solve for x by multiplying both sides of our equation by 5.
[tex]\frac{4x+1}{5}*5=\frac{15}{3}*5[/tex]
[tex]4x+1=5*5[/tex]
[tex]4x+1=25[/tex]
Let us subtract 1 form both sides of our equation.
[tex]4x+1-1=25-1[/tex]
[tex]4x=24[/tex]
Upon dividing both sides of our equation by 4 we will get,
[tex]\frac{4x}{4}=\frac{24}{4}[/tex]
[tex]x=6[/tex]
Therefore, the value of x is 6 units.
Do 1.5 cm, 3 cm, 1.5 cm make a triangle and what kind
The lengths 1.5 cm, 3 cm, and 1.5 cm cannot form a triangle because the sum of the lengths of the two shorter sides is equal to the length of the longest side, which does not satisfy the Triangle Inequality Theorem.
The question asks if lengths 1.5 cm, 3 cm, and 1.5 cm can form a triangle, and if so, what kind of triangle it would be. To determine whether these lengths can form a triangle, we use the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
For these lengths:
1.5 cm + 1.5 cm = 3 cm1.5 cm + 3 cm > 1.5 cm1.5 cm + 3 cm > 1.5 cmWe see that when we add the lengths of the two shorter sides (1.5 cm + 1.5 cm), it equals the length of the longest side (3 cm). According to the Triangle Inequality Theorem, the lengths do not meet the condition for forming a triangle because the sum must be greater than, not equal to, the length of the third side. Therefore, these lengths cannot form a triangle.

A $6,000.00 principal earns 8% annual interest, compounded semiannually (twice per year). After 35 years, what is the balance in the account?
A. $22,800.00
B. $39,600.00
C. $88,712.07
D. $93,429.71
Answer:
After 35 years balance in the account = $93429.71
Explanation:
We will applying the compound interest formula.
A = [tex] P(1 +\frac{r}{n})^{nt} [/tex]
Where,
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years
Given that,
P = $6000
r = 8% = [tex] \frac{8}{100} [/tex] = 0.08
n = 2 (because of twice in a year)
t = 35 years
[tex] A= 6000(1 + \frac{0.08}{2}) ^{2*35} [/tex]
A = 6000[tex] (1.04)^{70} [/tex]
A= $93429.71 (Option D)
solve for x in the equation x^2+10x+12=36
Answer: The required value of x is 2 or -12.
Step-by-step explanation: We are given to solve for x in the following equation :
[tex]x^2+10x+12=36~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We will be solving the given equation by the method of factorization.
From equation (i), we have
[tex]x^2+10x+12=36\\\\\Rightarrow x^2+10x+12-36=0\\\\\Rightarrow x^2+10x-24=0\\\\\Rightarrow x^2+12x-2x-24=0\\\\\Rightarrow x(x+12)-2(x+12)=0\\\\\Rightarrow (x-2)(x+12)=0\\\\\Rightarrow x-2=0,~~~~~~x+12=0\\\\\Rightarrow x=2,~-12.[/tex]
Thus, the required value of x is 2 or -12.
