Answer:
[tex]\dfrac{x}{2}+\dfrac{1}{3}[/tex]
Step-by-step explanation:
We need to find the value of [tex]((\dfrac{1}{4}x+\dfrac{3}{4}x-\dfrac{1}{2}x)+1+(\dfrac{-2}{3}))[/tex]
We can solve it as follows :
[tex]((\dfrac{1}{4}x+\dfrac{3}{4}x-\dfrac{1}{2}x)+1+(\dfrac{-2}{3}))\\\\=(\dfrac{x+3x-2x}{4})+1-\dfrac{2}{3}\\\\=\dfrac{2x}{4}+\dfrac{1}{3}\\\\=\dfrac{x}{2}+\dfrac{1}{3}[/tex]
Hence, the value of [tex]((\dfrac{1}{4}x+\dfrac{3}{4}x-\dfrac{1}{2}x)+1+(\dfrac{-2}{3}))[/tex] is equal to [tex]\dfrac{x}{2}+\dfrac{1}{3}[/tex].

So what you need to do is is how fast they traveled every ten miles once you do that take how fast they traveled every ten miles and multiply it by 9.
So it seems to me that 1 day for most people they walked 10 miles. So if it takes 7 days for them to get there you need to do 90 divided by 7 which will get you your answer.

Answer:
Option 1: 28 is the correct answer.
Step-by-step explanation:
The given expression for sum is:
[tex]\[ \sum_{n=1}^{4} {2n+2} = 1 \][/tex]
There will be four terms in the sum
We have to find the terms by putting n=1,2,3,4 as n=1 to 4
Putting n=1
[tex]=2(1)+2 = 2+2 = 4[/tex]
Putting n=2
[tex]=2(2)+2 = 4+2 = 6[/tex]
Putting n=3
[tex]=2(3)+2 = 6+2 = 8[/tex]
Putting n=4
[tex]=2(4)+2 = 8+2 = 10[/tex]
So the summation will expand to:
[tex]\[ \sum_{n=1}^{4} {2n+2} = 1 \] = 4+6+8+10 = 28[/tex]
Hence,
Option 1: 28 is the correct answer.
Karen has a cube that has a side length of 6 in. The net of the cube is shown.
Question: What is the surface area of the cube?
Answer:
[tex]Area = 216\ in^2[/tex]
Step-by-step explanation:
Given
[tex]L = 6[/tex] --- length
Required
Determine the surface area
The surface area of a cube is calculated as follows:
[tex]Area = 6L^2[/tex]
Substitute 6 for L
[tex]Area = 6 * 6^2[/tex]
[tex]Area = 6 * 36[/tex]
[tex]Area = 216[/tex]
Hence, the surface area of the cube is [tex]216in^2[/tex]
In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 21% of your total grade, each major test is worth 24%, and the final exam is worth 31%. Compute the weighted average for the following scores: 90 on the lab, 98 on the first major test, 71 on the second major test, and 79 on the final exam.
Answer:
the weighted score is 82.03
Step-by-step explanation:
The computation of the weighted score is as follows
= Respective scores × respective test or exam and score
= 0.21 × 90 + 0.24 × 71 + 0.24 × 71 + 0.31 × 79
= 18.9 + 21.6 + 17.04 + 24.49
= 82.03
Hence, the weighted score is 82.03
We simply applied the above formula so that the weighted score could be come

Food 14%
Clothing 17%
Entertainment 12 %
Auto 22%
Find the central angle for housing. If necessary, round to the nearest tenth.
Answer:
The circle graph is attached.
Step-by-step explanation:
a) Data and Calculations:
Monthly Expenses for a Family Budget
Expenses Percentage Degree
Housing 35% 130° (360° * 35%)
Food 14% 50° (360° * 14%)
Clothing 17% 60° (360° * 17%)
Entertainment 12% 40° (360° * 12%)
Auto 22% 80° (360° * 22%)
b) The result shows that Housing expense took more than one-third of the circle with auto expenses occupying the next biggest chunk of the circle. Clothing came third to occupy one-sixth of the circle, with food and entertainment trailing behind with less than one-sixth of the circle respectively.

rectangular flower bed is 120 in long and 240 in wide how many plants are needed if they are to be spaced 16 in
Answer:
45 plants
Step-by-step explanation:
Given that:
Length of bed = 120 in
Width of bed = 240 in
Perimeter of a rectangle is given by :
P = 2(length + Width)
Therefore,
P = 2(120 + 240)
Perimeter = 720 inches
If a spacing of 16 inches will be used ; number of plants needed ;
Perimeter / 16
= 720 in / 16 in
= 45

10. Use the perimeter formula. Collect terms, subtract* the constant, divide by the coefficient of the variable.
P = 2(L+W)
42 = 2(5x +(x-3))
21 = 6x -3 . . . . . . divide by 2, collect terms
24 = 6x . . . . . . . . add 3
4 = x . . . . . . . . . . divide by 6

11. Collect terms, subtract the constant, divide by the coefficient of the variable.
-8x -3(2x +1) = 67
-8x -6x -3 = 67 . . eliminate parentheses
-14x -3 = 67 . . . . . collect terms
-14x = 70 . . . . . . . add 3
x = -5 . . . . . . . . . . divide by -14
_____
* "Subtract" and "add the opposite" are the same mathematical operation. In both these problems, the constant we want to get rid of is -3, so we add 3 (the opposite of -3). Of course, that operation is done to both sides of the equation.
X + 8 = 5; X = ?
6 = X = 2; X = ?
X = 3 = 3; X = ?
X + 10 = 7; X = ?
36 - X = 6; X = ?
14 = X = 2; X = ?
50 = X = 5; X = ?
5X = 10; X = ?
X = 7 = 6; X = ?
X-4 = 2; X = ?

A 31.4n + 8.4 = 24
B -8.4n + 31.4 = 24
C 24 = 31.4n + (-8.4)
D 24 - 31.4 = -8.4n
I need help ASAP
24 = 31.4n + (-8.4) is the correct answer
Step-by-step explanation:
expression 31.4n -8.4 = 24 is the correct equation for the given sentence.
What is an expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.
Given, twenty-four is the same as 31.4 times a number plus negative 8.4.
Let " n " be the number
From the given data expression will be,
31.4 times a number
=> 31.4 * n
plus negative 8.4
=> 31.4n -8.4
Equals to twenty-four
=> 31.4n -8.4 = 24

A circle has an area of 256 square inches. If the radius of
the circle is multiplied by 4, what will be the area of the new
circle formed?
OA) 890 in.
OB) 1520 in.
OC) 4096 in
OD 5360 in.
Answer:
Option C (4096π in²)
Step-by-step explanation:
Area of the circle = 256π in²
We know that [tex]Area=\pi r^{2}[/tex] , where r = radius of the circle
So,
[tex]256\pi = \pi r^{2}[/tex]
Cancelling π from both the sides,
[tex]=> r^{2} = 256[/tex]
[tex]=> r = \sqrt{256} = 16[/tex]
The radius of the circle = 16 in.
When the radius is multiplied with 4 , new radius = 16×4 = 64 in.
New Area = [tex]\pi (64)^{2} =4096\pi \: in^{2}[/tex]

9514 1404 393
Answer:
₹172.25 at 4.5%
Step-by-step explanation:
The growth factor is the ratio of the values at the end and beginning of the second year:
multiplier = 188.10/180 = 1.045 = 1 + 4.5%
The amount put out is the amount at the end of the first year, divided by this growth factor.
P = A/(1+r) = 180/1.045 = 172.25
The sum put out is ₹172.25, and the rate of interest is 4.5%.
