Answer:
80 is the answer
Step-by-step explanation:
The direct variation is given by:
[tex]F=k\,\frac{m}{d^2}[/tex]
So given the values for each variable, we can find the constant of proportionality k:
[tex]F=k\,\frac{m}{d^2} \\60=k\,\frac{1470}{7^2} \\k = \frac{60*49}{1470} \\k=2[/tex]
Then we can now find what the value is when m = 2560 and d = 8 by using the proportionality equation with k = 2:
[tex]F=2\,\frac{m}{d^2} \\F=2\,\frac{2560}{8^2}\\F=80[/tex]

A is directly proportional to B and when A = 4 , B = 8 8. Find A when B = 44 . please can I have the working out
Answer:
A = 2
Step-by-step explanation:
If A = 4 when B = 88, we can divide both A and B by 2 to find their values.
88/2 = 44
4/2= 2
We can also check this by dividing 88 by 4 to figure out that A = 1 when B = 22
We can then multiply both the values of A and B to get a proportional relationship of A = 2, B = 44

Answer:
[tex]y = \frac{1}{2} x + \frac{1}{2} [/tex]
Step-by-step explanation:
equation of line formula:
[tex]y = mx + c[/tex]
m = slope
c = y-intercept
1) find m
slope formula:
[tex]m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1}} [/tex]
take 2 coordinates from the given graph and substitute the values into the slope formula
i) (-1,0)
[tex]x _{1} = - 1[/tex]
[tex]y_{1} = 0[/tex]
ii) (3,2)
[tex]x_{2} = 3[/tex]
[tex]y_{2} = 2[/tex]
substitute the values into the slope formula
[tex]m = \frac{2 - 0}{3 - ( - 1)} [/tex]
[tex]m = \frac{2}{4} [/tex]
[tex]m = \frac{1}{2} [/tex]
2) find the half equation of the line by substituting the value of m into the equation of line formula
[tex]y = \frac{1}{2} x + c[/tex]
3) find c by substituting either coordinate into the half equation
(3,2)
x = 3
y = 2
[tex]2 = \frac{1}{2} (3) + c[/tex]
[tex]2 = \frac{3}{2} + c[/tex]
[tex]2 - \frac{3}{2} = c[/tex]
[tex] \frac{1}{2} = c [/tex]
[tex]c = \frac{1}{2} [/tex]
4) find equation of line by substituting the value of c into the half equation
[tex]y = \frac{1}{2} x + \frac{1}{2} [/tex]

which ordered pair is a solution to the system of inequalities?
Answer:
Option A
Step-by-step explanation:
System of the inequalities is,
y ≥ 2x
y < x + 4
By satisfying these inequalities with the points given in the options we can get the answer.
Option (A). (2, 5)
y ≥ 2x
5 ≥ 2(2)
5 ≥ 4
True.
y < x + 4
5 < 2 + 4
5 < 6
True
Therefore, Option (1) is the answer.
Option (B) (1, 6)
y ≥ 2x
6 ≥ 2(1)
6 ≥ 2
True.
y < x + 4
6 < 1 + 4
6 < 5
False.
Therefore, it's not the solution.
Option (C) (2, 3)
y ≥ 2x
3 ≥ 2(2)
3 ≥ 4
False.
y < x + 4
4 < 2 + 4
4 < 6
True.
Therefore, It's not the solution.
Option (D) (1, 5)
y ≥ 2x
5 ≥ 2(1)
5 ≥ 4
True.
y < x + 4
5 < 1 + 4
5 < 5
False.
Therefore, It's not the solution.

Johnny's inspecting the finished toys in toy factory he found that 4 the toys were damaged and 16 were not based on this data how many of the next 20 toys would you expect to be damaged. Please explain I do not understand
Answer:
4 is expected to be damaged out of the next 20
Step-by-step explanation:
From the observation made, we have that 4 of the toys were damaged and 16 were not damaged
Thus, the probability of having a damaged toy is 4/20 = 1/5
Now, for the next 20; we have 1/5 of them expected to be damaged
So, the expected damaged number out of the next 20 will be:
1/5 * 20 = 4

Answer:
[tex]\frac{1}{2} x +x = 2 (x-4)[/tex]
Step-by-step explanation:
Suppose number is x
Following equation can be written from question statement

Rita bought 4 rulers for $4.00. If r represents the number of rulers purchased, which equation represents this situation?
Answer: 4r = 4
Step-by-step explanation:
Ruth bought 4 rulers and each ruler is to be represented by r. She therefore bought:
= 4r
She bought these for a total of $4.00 so the equation then becomes:
4r = 4.00
Equation representing situation is: 4r = 4
Bob completed a race in half of an hour. He ran 4 laps. Each lap was ran equally. How much of an hour did bob run on each lap?
Answer:
Time taken for each lap = 3/8 of an hour
Step-by-step explanation:
Given:
Time taken for 4 laps = [tex]1\frac{1}{2}[/tex] = 3/2 hours
Find:
Time taken for each lap
Computation:
Time taken for each lap = Time taken / Number of laps
Time taken for each lap = (3/2) / 4
Time taken for each lap = 3/8 of an hour

A square has a side length of (x+4). What is the expression that represents the area of the square?
x2+16x squared plus 16
x2+8x+16x squared plus 8 x plus 16
x2+16x+16x squared plus 16 x plus 16
x2+8x+8
The expression x² + 8x + 16 represents the area of the square.
What is the area of the square?The area of the square is defined as the product of the length and width.
Given data as:
A square has a side length of (x+4)
The area of the square = (x+4)(x+4)
The area of the square = (x+4)²
The area of the square = x² + 2(x)(4) + 4²
The area of the square = x² + 8x + 16
Hence, the expression x² + 8x + 16 represents the area of the square.
