Answer:
n = 5/√7
Step-by-step explanation:
(√7) 5 = 7n
5√7 = 7n
7n = 5√7
n = 5√7/7
n = 5/√7
-TheUnknownScientist
(√7)5 = 7n
Divide both sides by n.
(√7)5/7 = n

Step-by-step explanation:
create a model or equation that will represent to the amount of relief each family will receive bearing in mind that the number of families will vary.
Missing Information
Suppose the officials conducted a survey for 4 days to determine the actual number of families residing in the barangay and the secretary constructed a tableto keep track of the data.
Day 0:
Number of families: 850
Amount of relief each family will receive: 520
Answer:
f(x) = 442000/x
Step-by-step explanation:
Given
The data in the above table
Required
Determine a model or equation
First, we need to determine the amount of relief for all families.
Using data in day 0.
Total Amount = 850 * 520
Total Amount = 442000
Next, we determine the function of equation.
Let the number of families he represented by x
The function or equation is gotten by dividing the total amount by the number of families.
Hence:
f(x) = Total Amount ÷ x
Substitute values for total amount and x
f(x) = 442000/x
Hence, the model that satisfies the given information is:
f(x) = 442000/x

a car travels from point s at (-5,7) to point t at (-5,-1). if each unit represents 20 miles, how long will it take the car to travel this distance, traveling at 40 miles per hour?
Answer:
The value is [tex]t = 4 \ hours[/tex]
Step-by-step explanation:
From the question we are told that
The initial position of the car is [tex]x_i , y_i = (-5,7)[/tex]
The final position of the car is [tex]x_f , y_f = (-5,-1)[/tex]
The speed of the car is [tex]v = 40 \ miles / hour[/tex]
Generally the distance covered by the car along the x-axis is
[tex]x = -5 - [- 5][/tex]
=> [tex]x = 0[/tex]
Generally the distance covered along the y-axis is
[tex]y = y_i - y_f[/tex]
=>[tex]y = y_i - [-1][/tex]
=> [tex]y = 8[/tex]
Generally the resultant distance covered is
[tex]R = \sqrt{x^2 + y^2}[/tex]
=> [tex]R = \sqrt{0^2 + 8^2}[/tex]
=> [tex]R = 8[/tex]
From the question we are told that 1 unit of the distance covered is 20 miles so
8 units is
[tex]r = 8 *20[/tex]
=> [tex]r =160 \ miles[/tex]
Generally the time taken is mathematically represented as
[tex]t = \frac{r}{v}[/tex]
=> [tex]t = \frac{160}{ 40}[/tex]
=> [tex]t = 4 \ hours[/tex]
Find f(9) if f(x) = 2x+6
Answer:
24
Step-by-step explanation:
To do this all you need to do is replace x with 9
F(9) = 2(9) + 6
2 x 9 = 18
18 + 6 = 24
The answer is 24

How many groups of 5 are in the product of 523 and 45
The larger the two numbers is one more than four times the small number. if the sum of the numbers is 106,find the two numbers
Answer:
Smaller no. = 21
Larger no. = 85
Step-by-step explanation:
Smaller no. = y
Larger no. = 4y + 1
y + (4y + 1) = 106
y + 4y + 1 = 106
5y + 1 = 106
5y = 106 - 1
5y = 105
y = 105/5
y = 21
Smaller no. = y = 21
Larger no. = 4y + 1 = 4×21 + 1 = 84 + 1 = 85

Vrite and simplify an expression to find he total cost of x pencils , 1 poster board , and (x + 1) notebooks.
Answer:
The expression to find the total cost of x pencils, 1 poster board, and (x + 1) notebooks will be:
[tex]C=xp+b+nx+n[/tex]
Step-by-step explanation:
Consider '[tex]x[/tex]' be the number of pencils which were bought
Consider '[tex]p[/tex]' denotes the cost of [tex]1[/tex] pencil
Consider '[tex]b[/tex]' denotes the cost of [tex]1[/tex] poster board
Consider '[tex]x+1[/tex]' be the number of notbooks which were bought
Consider '[tex]n[/tex]' denotes the cost of [tex]1[/tex] notebook
As we have to find the total cost. Let 'C' denotes the total cost
so the expression becomes
[tex]C=xp+b+\left(x+1\right)n[/tex]
simplifying
[tex]C=xp+b+nx+n[/tex]
Therefore, the expression to find the total cost of x pencils, 1 poster board, and (x + 1) notebooks will be:
[tex]C=xp+b+nx+n[/tex]

IIf two ounces of cheese has 200 calories, how many calories are in 5 ounces of cheese?
Answer:
500 calories
Step-by-step explanation:
200 / 2 = 100
1 ounce = 100 calories
5 * 100 = calories.
OR
200 * 5 = 1000
1000 / 2 = 500
Therefore, 5 ounces of cheese = 500 calories.
Find x in the following solution: x+x+10+2x-6=180
Answer:
X = 44
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
x=44
Step-by-step explanation:
First you add the all the x's.
4x+10-6=180
Then you subtract 6 from 10
4x+4=180
Next, you add subtract 4 from both sides.
4x=176
Divide by 4 and you get 44.
176/4
x=44
