PLSS HELP IT WILL MAKE ME FAIL
The number of times that the value of the digit 1 in the population of Cleveland in this value is 10.
How to illustrate the information?Based on the information, it should be noted 7 is in ten thousand place for Memphis. This means that it represents 70000.
It should be noted the 1 in Denver is in the same place. It represents 10000. On Cleveland, this is 1000.
Therefore, the number of times will be:
= 10000 / 1000
= 10
Therefore, the correct option is 10.

Answer:

Step-by-step explanation:
a rectangle has perimeter 24 m. express the area a of the rectangle as a function of the length, l, of one of its sides.
The Expression for the Area a of the rectangle as a function of length L is given by A(L) = 12L - L^2 .
Let,
length, L, and the width, W, are components that help determine the area, A, and the perimeter, P of the rectangle. These are given by the following equations
A=LW
P=2L+2W
Given,
Perimeter of the Rectangle = 24m.
We are asked to express the perimeter of the rectangle as a function of the length, L, of one of its sides.
We will first set up the equation of the Perimeter of the rectangle. We can let the width of the rectangle be W.
P = 2L+2W
24 = 2L+2W
12 = L+W
W = 12-L
Since we want to express the Area as a function of L, we have to find the value of W in terms of L. This is so we can eliminate the width in the equation for the Area. The Area as a function of L is as follows.
A(L, W) = LW
A(L) = L(12-L)
A(L) = 12L-L^2
Therefore, the Area as a function of L is given by A(L) = 12L-L^2.

Answer:
16,300,000 viewers
Step-by-step explanation:
We have two ordered pairs and we can write an equation in the slope intercept form of the line from the information that we have.
y = mx + b y is the number of viewers and x in the number of minutes of ads.
m is the slope. That is the change in y over the change in x. We will use the two points given to find this.
(14, 10,000,000) (25, 17,000,000)
slope:
[tex]\frac{y{1}- y{2} }{x_{1}-x_{2} }[/tex] = [tex]\frac{17,000,000 - 10,000,000}{25-15}[/tex] =[tex]\frac{7,000,000}{10}[/tex] = 700,000
Now we need the b or the y-intercept. We will use the slope and one of the points to find this. We could use either point. I am going to use the point (15, 10,000,000)
y = mx + b
I will use 10,000,000 for y
I will use 15 for x
I will use 700,000 for the slope.
I will plug these numbers in and solve for b
10,000,000 = 700,000(15) + b
10,000,000 = 10,500,000 + b Subtract 10,500,000 from both sides
-500,000 = b
Now we can write the equation
y = mx + b
y = 700,000x -500,000 Plug is the 24 for x to solve for the number of views.
y = 700,000(24) -500,000
y = 16,800,000 - 500,000

Ava read a total of 40 books over 5 months. If Ava has read 72 books so far, how many months has she been with her book club? Assume the relationship is directly proportional.
========================================================
Explanation:
She read 40 books over 5 months. This means her unit rate is 8 books per month (since 40/5 = 8)
x = number of months
(unit rate)*(number of months) = total books read
8x = 72
x = 72/8
x = 9
-------------
Another way to solve
(40 books)/(5 months) = (72 books)/(x months)
40/5 = 72/x
40x = 5*72 ... cross multiplying
40x = 360
x = 360/40

Hans needs to rent a moving truck. Suppose Company A charges a rate of $40 per day and Company B charges a $60 fee plus $20 per day. for what number of days is the cost the same. Please also explain how you got the answer
Answer: x=3
Step-by-step explanation:
1. Hans needs to rent a moving truck. Suppose Company A charges $40.00 per day and Company B charges a $60.00 fee plus $20.00 per day, for what number of days is the cost the same?
Let x = # of days, since Company A charges $40/day then cost after x days = 40x
Let x = # of days, since Company B charges $20/day plus $60 fee, then cost after x days = 20x + 60
a. For what # of days is the cost the same?
When the cost is the same => 40x = 20x + 60
40x - 20x = 60
20x = 60
x = 60/20
x = 3
The cost is the same after 3 days.
Checking:
$40(3) = $20(3) + $60
$120 = $60 + $60
$120 = $120

y = -4.2x + 7.9 in standard form
The equation of the line y = -4.2x + 7.9 expressed in standard form is 42x + 10y = 79.
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is written as axe + by = c, where a and b are the coefficients of the variables x and y, respectively, and c is a constant. On the other hand, we can write the equation in point-slope form, (y - y1) = m, if we know the slope m and a point on the line (x, y).
Given the equation of a line, multiply both sides by 10 to turn the decimals into integers.
y = -4.2x + 7.9
10y = 10(-4.2x + 7.9)
10y = -42x + 79
Rewriting it in standard form ax + by = c,
10y = -42x + 79
42x + 10y = 79

Given L is between N and M, NL = 6x - 5, LM = 2x + 3, and NM = 4x + 9. Determine if L is the midpoint of segment MN. Justify your answer using sound mathematical reasoning.
Answer: L isn't the midpoint of segment MN.
Step-by-step explanation:
NL+LM=NM
6x-5+2x+3=4x+9
8x-2=4x+9
8x-2+2=4x+9+2
8x=4x+11
8x-4x=4x+11-4x
4x=11
Divide both parts of the equation by 2:
2x=5.5
NL=6x-5
NL=(2x)(3)-5
NL=(5,5)(3)-5
NL=16.5-5
NL=11.5
LM=2x+3
LM=5.5+3
LM=8.5
NL≠LM
Hence, L isn't the midpoint of segment MN.
In summary, based on the given lengths and mathematical reasoning, we have determined that point L is the midpoint of segment MN because the lengths of NL and LM are equal when x = 2.
We must compare the lengths of the two segments NL and LM and see if they are identical in order to establish whether point L is the midpoint of segment MN.
NL = 6x - 5
LM = 2x + 3
The lengths of NL and LM ought to be equal if L is the middle of segment MN. To put it another way, NL and LM ought to be equal.
Constructing the equation
6x - 5 = 2x + 3
Now, solve for x:
6x - 2x = 3 + 5
4x = 8
x = 2
As soon as we know the value of x, we can put it back into the NL and LM formulas to get their lengths at x = 2:
NL = 6x - 5 = 6 * 2 - 5 = 12 - 5 = 7
LM = 2x + 3 = 2 * 2 + 3 = 4 + 3 = 7
The lengths of NL and LM are both 7 units.
Point L is in fact the middle of segment MN because both segments NL and LM have similar lengths.

A leather recliner with a regular price of $795.00 is on sale for 15% off. What is the sale price of the recliner?
Answer:
$675.75
Step-by-step explanation:
To find the sale price of the recliner, we can multiply 15% by the regular price.
15% = 0.15
(0.15)(795.00) = $119.25
This gives us the amount that the sale takes off from the regular price. We can subtract that from the regular price to find the sale price.
795.00 - 119.25 = $675.75
A bonus shortcut way to get our answer would be to subtract 15% from 100%.
100% = 1.00
1.00 - 0.15 = 0.85
This tells us that the sale price is 85% of the regular price. Using this information, we can multiply 85% by the regular price to also get our sale price.
85% = 0.85
(0.85)(795.00) = $675.75

The value of the angle θ required in the water main for the turn from north to east is 87.40°.
According to the statement
We have to find that the value of the angle.
So, For this purpose, we know that the
An angle is created when two straight lines or rays meet at a standard endpoint.
From the given information:
a main is to be constructed with a 20% grade within the north direction and a tenth grade within the east direction.
Then
Let n = North
and e = east
Then
using vectors,
n = j + 0.20 k
e = i + 0.25 k
And the
n · e = 1x0 + 0x1 + 0.20×0.25 = 0.05
Now take magnitude then
|n|·|e| = i(1² + 0.20²)·i(1²+0.25²) = 1.105
Now,
E° = arccos((n · e)/|n|·|e|)
E° = arccos(0.05/1.105)
E° = arccos (0.0452)
E° = 87.40°
