Answer: 238.8
Step-by-step explanation:
To get an average, you add the weights together, the sum. And then you divide by how many children there was.
To go backwards, you'd times the average by the amount of children there were, 3, to get the sum
79.6 times 3 is 238.8
The accompanying graph is a sketch of the function
y = f(x) over the interval 0 SXS 7.
What is the value of (f. f)(6)?
1) 1 2) 2 3) (4) -2
A composite function combines two or more functions to generate a new function.
The value of [tex]\mathbf{f(f(6))}[/tex] is -2
The require parameter is:
[tex]\mathbf{f(f(6))}[/tex]
First, we calculate f(6)
From the graph (see attachment)
[tex]\mathbf{f(6) = 2}[/tex]
So, the function [tex]\mathbf{f(f(6))}[/tex] becomes:
[tex]\mathbf{f(2)}[/tex]
In other words,
[tex]\mathbf{f(f(6)) = f(2)}[/tex]
Next, we calculate f(2)
From the graph
[tex]\mathbf{f(2) = -2}[/tex]
So:
[tex]\mathbf{f(f(6)) = -2}[/tex]
Hence, the value of [tex]\mathbf{f(f(6))}[/tex] is -2

the angle measures of a triangle are in the ratio 5:6:7. find the angle measures of the triangle
Answer:
50°, 60°, 70°
Step-by-step explanation:
Sum the parts of the ratio, 5 + 6 + 7 = 18 parts
The 3 angles in a triangle sum to 180° , then
180° ÷ 18 = 10° ← value of 1 part of the ratio, then
5 parts = 5 × 10° = 50°
6 parts = 6 × 10° = 60°
7 parts = 7 × 10° = 70°
The angle measures of the triangle are 50° , 60° , 70°
what is 56x56 and how much can i give away and still have 500

Answer:
[tex] x_{1} = - \sqrt{2} \: .\: x_{2} = - 1 \: . \: x_{3} = 1 \: . \: x_{4} = \sqrt{2} [/tex]
Step-by-step explanation:
x⁴ - 3x² + 2 = 0
x^2×2 - 3x² + 2 = 0
(x²)² - 3x² + 2 = 0
t² - 3t + 2 = 0

Liam knows the key to making creamy risotto, a rice dish, is to add the liquid to the rice gradually. He adds 5 ladles of chicken broth to his rice before adding seasoning, and he continues to add 2 ladles of broth each minute afterwards.Write an equation that shows the relationship between the number of minutes since Liam added the seasoning, x, and the total number of ladles of broth he has added, y.
The equation that shows the relationship between the number of minutes and total number of ladles of broth is y = 2x + 5
Let x represent the number of minutes and y represent the total number of ladies.
Since he adds 2 ladles of broth each minute and he has 5 ladies initially, hence:
y = 2x + 5
The equation that shows the relationship between the number of minutes and total number of ladles of broth is y = 2x + 5

You have $6 to spend on lunch. The drinks cost $1.25 each and the salad
costs $0.20 per ounce. Write an equation in standard form that models
this situation.
1. 1.25 +.20x = 6
2. 1.25x + 20y = 6
3. 1.45x = 6
4. 1.25x + 6y = 20
Answer:
1. 1.25 + .20x = 6
Step-by-step explanation:
You will most likely just buy one drink and multiple ounces of salad with the 6 dollars you have to purchase a whole meal.
.20x, where x equals how many ounces you purchase
1.125 for the one drink
When set equal to 6 dollars you are able to find how much salad plus a drink you can purchase in total.
