The scale used on a map is 1 inch = 44 miles. How many miles does 9 inches on the map represent
Answer:
9 inches on the map represents 396 miles.
Step-by-step explanation:
Here let's convert 44 miles to inches.
44 miles is 2787840 inches.
So according to the map, 1 inch = 2787840 inches.
We need to multiply both of these values by 9 to find out how many miles 9 inches represents.
1 inch = 2787840 inches
1 * 9 inches = 2787840 * 9 inches
9 inches = 25090560 inches.
Then convert back to miles.
25090560 inches = 396 miles.
That means, 9 inches on the map represents 396 miles.
There are six professors teaching the introductory discrete mathematics class at a university. The same final exam is given by all six professors. If the lowest possible score on the final is 0 and the highest possible score is 100, how many students must there be to guarantee that there are two students with the same professor who earned the same final examination score
Answer:
607 students
Step-by-step explanation:
To solve this question means we have to use Pigenhole principle which states that if y number of items are put into z number of containers, with y > z, then it means that that at least one container must definitely contain more than one item.
Now, let's find the number of boxes and objects:
If possible scores are from 0 to 100 with both inclusive it means number of possible scores = 101.
Now, If there was only one professor grading the students, in order to ensure that that there are two students with the same professor who earned the same final examination score,
The number of students would have to be = 101 + 1 = 102 students
Meanwhile, for each student, since there are 6 professors, the possible combination for a score will be = 6 possible combinations.
Therefore, number of students that will guarantee that there are two students with the same professor who earned the same final examination score must be a minimum of: (6 × 101) + 1 = 607
Select the correct difference. 5d^2 + 4d - 3 less 2d^2 - 3d + 4
Answer:
[tex]3d^2+ 7d- 7[/tex]
Step-by-step explanation:
Given
[tex]P_1 = 5d^2 + 4d - 3[/tex]
[tex]P_2 = 2d^2 - 3d + 4[/tex]
Required
P1 less P2
This means that we subtract P2 from P1.
So, we have:
[tex]P_1 - P_2 = 5d^2 + 4d - 3 - (2d^2 - 3d + 4)[/tex]
Remove bracket
[tex]P_1 - P_2 = 5d^2 + 4d - 3 - 2d^2 + 3d - 4[/tex]
Collect like terms
[tex]P_1 - P_2 = 5d^2 - 2d^2+ 4d + 3d- 3 - 4[/tex]
[tex]P_1 - P_2 = 3d^2+ 7d- 7[/tex]
The difference is: [tex]3d^2+ 7d- 7[/tex]
Which ordered pair represents the y-intercept of the graph of the equation y = - 4 x - 7 ?
Answer:
(0, -7)
Step-by-step explanation:
Since -4x is the slope, then -7 is the y-intercept.
For finding y intercept we substitute x=0
y = -7
The ordered pair would be
(0,-7)

Given the matrix;
[tex]-2\left[\begin{array}{ccc}x&-1\\3&5\end{array}\right] + \left[\begin{array}{ccc}3&8\\-1&6\end{array}\right] = \left[\begin{array}{ccc}x&10\\-7&-4\end{array}\right][/tex]
Converting to equations
From the first row of each matrices
-2x + 3 = x
Collect the like terms
-2x - x = -3
-3x = -3
x = -3/-3
x = 1
Hence the value of x is 1
what is the least common denominator of 1/2, 2/3, and 3/8
Answer: 24
Step-by-step explanation:
Answer:
24
Step-by-step explanation:
For the least common denominator, we have to find the smallest number that all fo them multiply to.
2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26
3, 6, 9, 12, 15, 18, 21, 24, 27, 30
8, 16, 24, 32
i think we can see something
24 is the most common number between them all, so the fractions will be
12/24 (1/2), 16/24 (2/3), and 9/24 (3/8)

Which expression is equivalent to this: "3 multiplied by z"?
Answer:
3z
Step-by-step explanation:
When you write a number followed by a variable with no operation in between them, it means multiplication.
3 multiplied by z is 3 * z, but you can write it without the multiplication sign simply as 3z.
What is
7(2b + 3) - 2b
Pls I need help fast
Answer:
b= = - 7/4 or -1.75
Step-by-step explanation:
14b +21 -2b=0
12b +21=0
12b= -21
b= -21/12
b= - 7/4 or -1.75
Answer:
i dont know what you neccesarily want but here are two answers b=-7/4 or -1 3/4 other answer is 12b+21
Step-by-step explanation:
first, you have to set this question equal to 0.
7(2b+3)-2b=0
now you have to distribute the 7 to everything inside the parentheses.
14b+21-2b=0
combine like terms
12b+21=0
you can stop here and take this answer if this is the one you want
now subtract each side by 21
12b=-21
divide each side by 12
b=-21/12
simplify
b=-7/4
hope this helps! have a nice day :)
What three-dimensional figure is represented by the net shown below?
A cube
B square pyramid
C rectangular prism
D rectangular pyramid
Answer:
C
Step-by-step explanation:
The net, if you imagine it folded up, will look like a long box.
Because all the dimensions are not equal, the figure cannot be a cube. Both square and rectangular pyramids have 5 faces, unlike this net.
A net of a rectangular prism, however, will have different dimensions for [tex]l[/tex] and [tex]w[/tex], and have 6 faces. So, the answer is C, rectangular prism.
Good luck ^^
The three-dimensional figure represented by the net shown below is a rectangular prism.
Option C is the correct answer.
What is a prism?A prism is a three-dimensional object.
There are triangular prism and rectangular prism.
We have,
From the figure,
We see that it is an open rectangular prism.
All the open sides are rectangular in shape.
If we fold all the sides it will form a rectangular prism.

The surface area S of a cube with the side length a is given by the formula S=6a^2. Find the side length of a cube with the Surface are of 700 square inches. Round to the nearest integer
Answer:
Side length of cube = 10.80 inch (Approx.)
Step-by-step explanation:
Given:
Surface area of cube = 700 square inches
Find:
Side length of cube
Computation:
We know that all sides of cube are equal
Surface are of cube = 6(Side)²
By putting 700 as surface are of cube in the formula;
700 = 6(Side)²
(Side)² = 700 / 6
(Side)² = 116.667
Side = √116.667
Side = 10.801
Side length of cube = 10.80 inch (Approx.)
