Use +,-,x, ÷ and parentheses to connect the numbers 1,3,5 and 7 such that the result is 24.
Answers
Answer: (3-1)×(7+5)
Step-by-step explanation:
There are mainly several ways to get 24
- 2×12
- 3×8
- 4×6
- add all of them together
- complicated ones can include large numbers minus another large number
Use try-check-revise, to find the way that fits 24
For this question, we used 2×12, which results in (3-1)×(7+5)
Hope this helps!! :)

An open circle is used to graph strict inequalities, which means the inequality does not include the value at the boundary. The inequalities that would have an open circle when graphed are:
x > 5.4
One-half less-than x
x > 0
if an inequality states less than OR equal to that means the circle will be closed when graphed

Janine can use up to 150 one-inch blocks to build a solid, cube-shaped model. What are the dimensions of the possible models that she can build? How many blocks would Janine use for each model? Explain.

Answer:
A total of 12 dimensions to make perfect cubes. 1x1, 2x2, 3x3, 4x4, 5x5, 6x6, 7x7, 8x8, 9x9, 10x10, 11x11, 12x12. Can i get a brainliest?
Step-by-step explanation:
1x1=1
2x2=4
3x3=9
4x4=16
5x5=25
6x6=36
7x7=49
8x8=64
9x9=81
10x10=100
11x11=121
12x12=144
Janine can build 12 models of equal dimension (1x1), (2x2), (3x3), (4x4), (5x5), (6x6), (7x7), (8x8), (9x9), (10x10), (11x11), (12x12).
What is a cube?A three-dimensional object with six equal square faces is called a cube. The cube's six square faces all have the same dimensions.
A cube is become by joining six squares such that the angle between any two adjacent lines should be 90 degrees.
The surface area of the cube = 6 side².
The volume of the cube = side³.
Given that Janine can build up to 150 inches² area of cube.
Area of cube < 150
So,
13x13 = 169 > 150 And 12x12 = 144 < 150
So Janine can use up to 12 inches cube
Possible dimensions up to 12 inches are
(1x1), (2x2), (3x3), (4x4), (5x5), (6x6), (7x7), (8x8), (9x9), (10x10), (11x11), (12x12).
Hence "Janine can build 12 models of equal dimension (1x1), (2x2), (3x3), (4x4), (5x5), (6x6), (7x7), (8x8), (9x9), (10x10), (11x11), (12x12)".

A rectangular prism with dimensions 5 inches by 13 inches by 10 inches was cut to leave a piece as shown in the image. What is the volume of this piece? What is the volume of the other piece?
HELP
Answers
The volume of the original rectangular prism is given by:
V1 = length x width x height
= 5 inches x 13 inches x 10 inches
= 650 cubic inches
To find the volume of the remaining piece, you need to determine its dimensions. If you have an image or a description of the piece, you can use that information to calculate its volume. Once you have the volume of the remaining piece, you can subtract it from the volume of the original rectangular prism to get the volume of the piece that was cut out.
To find the volume of the other piece, you can subtract the volume of the piece that was cut out from the volume of the original rectangular prism:
V2 = V1 - V_cut_out
where V_cut_out is the volume of the piece that was cut out.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
(HELP PLEASEE SOMEONE I'LL GIVE BRAINLIESTT if correct) If b/a=c/b=d/c=2/3, find the value of a:b:c:d
Answers
Answer:
3:3:2:3
Step-by-step explanation:
b/a = 2/3 = b is 2 a is 3
c/b = 2/3 = c is 2 b is 3
d/c=2/3 = d is 2 c is 3
All you have to do to solve this question is to lay out all the variables and see which number matches with which.
Answer:
might be c
Step-by-step explanation:
a − b/c − d = 2 and a − c/b − d = 3 will hold for any values of a, b, c and d as long as
b≠0; c≠0
b/c − c/b = 1
and
a − d = 2 + b/c
If you let x = b/c, b/c − c/b = 1 becomes x − 1/x = 1
⇒ x2 − x − 1 = 0
⇒ x = 1.618 or x =−0.618.
So
b/c = 1.618 or b/c =−0.618 is required.
The values of a, b, c and d are arbitrary subjected to
b/c = 1.618 or b/c =−0.618 and a − d = 2 + b/c.
Let c and d be the free variables, and let x = d/c then
a − d/b − c = (1 − c/b)x + 2 + c/b

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.
b) The correct expression is given as follows: -8.6b + 28.
How to simplify the expression?The expression in the context of this problem is defined as follows:
(-3.78b + 12) - (4.82b - 16).
The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:
-3.78b + 12 - 4.82b + 16.
This is the step where Maddie made the first error.
Then, to simplify the expression, we combine the like terms, as follows:
b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.
