The Answer Is B.2-1/3
Hope It Helps Mark Me The Brainlyest
The expression −2/3(3-1/2)(-1) is equivalent to -5/3.
Explanation:To simplify the expression −2/3(3-1/2)(-1), we can start by simplifying the expressions within the parentheses.
3-1/2 = 6/2 - 1/2 = 5/2
Next, we can multiply the expression −2/3(5/2)(-1).
−2/3(5/2)(-1) = -2/3 * 5/2 * -1 = -10/6 = -5/3
Therefore, the expression is equivalent to -5/3.
Point A is located at –24 and point C is located at 36 on the number line below. Which value would represent point B, halfway between point A and point C?
Answer:
Point B will be 6
Step-by-step explanation:
We have point A= -24 and point B = 36, we want to know point B which is halfway between points A and C.
To find the middle between two points we have to add the two numbers and divide them by 2:
We would have:
(A+C)/2
We substitute the values of A and C:
B = (-24+36)/2
B = 12/2
B = 6.
We can also write this on a number line and get point B by counting how many numbers there are in between point A and C, and this result divides it by 2. This is in the attachment.

c. 7m - 2 = 8m + 4 - m
d. 8y + 9 = 8y - 3
Answer:
Option b - [tex]5w + 8 - w = 6w - 2( w - 4)[/tex]
Step-by-step explanation:
To find : Which equation is an identity?
Solution :
Option a - [tex]11- (2v + 3) = -2v - 8[/tex]
If we open the parenthesis,
[tex]11- 2v -3 = -2v - 8[/tex]
[tex]-2v+8\neq -2v - 8[/tex]
No identity applied.
Option b - [tex]5w + 8 - w = 6w - 2( w - 4)[/tex]
If we apply distributive property, [tex]a(b+c)=ab+ac[/tex]
[tex]5w + 8 - w = 6w - 2w+8[/tex]
[tex]4w+8= 4w+8[/tex]
Distributive identity is applied.
Option c - [tex]7m - 2 = 8m + 4 - m[/tex]
Solve by subtracting in RHS

If two pyramids are similar and the ratio between the lengths of their edges is 3:11, what is the ratio of their volumes?
Answer: The ratio of the volumes of two pyramids is 27 : 1331.
Step-by-step explanation: Given that two two pyramids are similar and the ratio between the length of their edges is 3 : 11.
We are to find the ratio of the volumes of two pyramids.
Let a units and b units be the lengths of the edges of the two pyramids.
The, according to the given information, we have
[tex]a:b=3:11.[/tex]
We know that the ratio of the volumes of two similar pyramids is equal to the ratio of the cubes of the lengths of edges of the two pyramids.
Therefore, the ratio of the volumes of two pyramids will be
[tex]V:V'=\dfrac{V}{V'}=\dfrac{a^3}{b^3}=\left(\dfrac{a}{b}\right)^3=\left(\dfrac{3}{11}\right)^3=\dfrac{27}{1331}=27:1331\\\\\\\Rightarrow V:V'=27:1331.[/tex]
Thus, the ratio of the volumes of two pyramids is 27 : 1331.

a. Write an expression that represents the following expression using the variable b: "Billy's age in 8 years." b. Write an equation using the expression above if in 8 years Billy will be 21 years old. c. How old is Billy now? d. Write and solve a word problem that matches the equation: a - 6 = 10.
Answer:
"Billy's age in 8 years", this refers to a future age, which implies adding 8 years to the present age. The expression would be:
[tex]B+8[/tex]
"In 8 years Billy will be 21 years", this expression, using the first one too, would be:
[tex]B+8=21[/tex]
How old is Billy now?
The answer to this question is the solution of the second equation:
[tex]B+8=21\\B=21-8=13[/tex]
Billy is 13 years old now.

"the sum of the squares of two consecutive odd integers is 2594. find the two integers."
Final answer:
To find two consecutive odd integers whose squares sum to 2594, a quadratic equation is set up and solved, revealing that the integers are 35 and 37.
Explanation:
To solve for two consecutive odd integers whose squares sum to 2594, we can set up equations based on the characteristics of odd integers. Let the smaller integer be n, then the next consecutive odd integer would be n + 2.
The equation based on the sum of the squares of the two numbers is then:
n2 + (n + 2)2 = 2594
Solving this equation:
n2 + n2 + 4n + 4 = 25942n2 + 4n - 2590 = 0n2 + 2n - 1295 = 0Solving the quadratic equation we find that n = 35 and n + 2 = 37. Hence, the two consecutive odd integers are 35 and 37.
Dr. Cheeks tries to run at least 45 rotations on her hamster wheel each week. She has already run 6 rotations. Which inequality shows how many more rotations, r, she would have to run to meet her weekly goal?
A. r-6>45
B. r-6>45
C. r+6>45
D.r+6<45
Answer: C. r+6>45
Step-by-step explanation:
Since, Dr. Cheeks tries to run at least 45 rotations on her hamster wheel each week.
If she runs r rotations then, for the value of r, [tex]45\leq r[/tex]
Since, If she has already 6 rotations
Therefore total rotation she has = r+6
Thus, if [tex]45\leq r[/tex] ⇒[tex]45<x+6[/tex]
So, Option C is the correct option.
The inequality of option C r+6 > 45 shows the rotations, r, she would have to run to meet her weekly goal.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Dr. Cheeks tries to run at least 45 rotations on her hamster wheel each week.
She has already 6 rotations but if she runs r rotations then, for the value of r, 45 ≤ r
The total rotation she has = r+6
Thus, 45 ≤ r
= 45 < r + 6
or r+6 > 45
So, Option C is the correct option.

Which of the following statements are true ?
The true statements for the triangle ABC where DE is perpendicular to AC is given by option D. The segment DE bisects the segment AC.
In triangle ABC, B-D-C, and A-E-C, with E being perpendicular to AC and AE = EC.
A. The segment BD bisects the segment EC.
This statement is false. Since E is the midpoint of AC (AE = EC), and E is perpendicular to AC, B-D-C no relation.
B. The segment ED is congruent to the segment DC.
This statement is not necessarily true. We only know that AE = EC, which implies that DE = EC since E is the midpoint of AC. However, we don't have enough information to conclude that ED is congruent to DC.
C. The segment BD is perpendicular to the segment EC.
This statement is not necessarily true. While we know that E is perpendicular to AC, it does not imply that BD is perpendicular to EC.
The perpendicularity of BD and EC depends on the specific configuration of the triangle, and the given information is not sufficient to determine this relationship.
D. The segment DE bisects the segment AC.
This statement is true. Since E is the midpoint of AC (AE = EC), DE passes through E and will indeed bisect AC.
Therefore, the true statements for the given triangle is
option D. The segment DE bisects the segment AC.

The perimeter of a rectangular field is 320 yd. the length is 80 yd longer than the width. find the dimensions.
The dimensions of a rectangular field is width = 40 yd and length = 120 yd.
What is a rectangle?
A rectangle is one of the types of quadrilaterals in which all four angles are right angles or equal to 90 degrees. It is four-sided polygon in which the opposite sides are parallel and equal to each other.
For the given situation,
Let the width of the rectangle, w = x
The length is 80 yd longer than the width.
The length of the rectangle, l = x + 80.
The perimeter of a rectangular field = 320 yd.
The formula of perimeter of rectangle is
[tex]P=2(w+l)[/tex]
On substituting the above values,
⇒ [tex]320=2(x+x+80)[/tex]
⇒ [tex]320=2(2x+80)[/tex]
⇒ [tex]2x+80=\frac{320}{2}[/tex]
⇒ [tex]2x+80=160[/tex]
⇒ [tex]2x=160-80[/tex]
⇒ [tex]2x=80[/tex]
⇒ [tex]x=\frac{80}{2}[/tex]
⇒ [tex]x=40[/tex]
Thus width = [tex]40[/tex] and
length = [tex]40+80[/tex]
⇒ [tex]120[/tex]
Hence we can conclude that the dimensions of a rectangular field is width = 40 yd and length = 120 yd.
