In a soup kitchen, 22 pounds of rice was used during the lunch. If 110 people came to have lunch, about how many pounds of rice was used by each person?
Answer:
0.2 pounds of rice
Step-by-step explanation:
To find how much rice was used by each person, divide 22 by 110
22/110
= 0.2
So, each person used 0.2 pounds of rice

Solve the equation x^2 – 5 = √ x – 2 by using successive approximation-
9514 1404 393
Answer:
x ≈ 2.367796
Step-by-step explanation:
There are a number of ways to use "successive approximation" to find a solution to an equation. You have not specified the method or the required accuracy.
__
One of the more tedious is the bisection method, which computes the value of the function at the midpoint of an interval, to see if that midpoint should be a new interval bound. This method requires about 3 iterations per decimal place of the answer.
Another method is the secant method. It computes the x-intercept of the secant line joining the points at the ends of the interval containing the solution. The function value at this x-intercept is used to see if that point should be a new interval bound. This method converges slightly faster than the bisection method. It is speeded by adjusting both ends of the interval.
Newton's method iteration converges at a quadratic rate, nearly doubling the number of correct decimal digits at each iteration. This works in a fashion similar to the secant method, except the x-intercept is computed from the function value and its derivative, not from points at the ends of an interval.
__
We assume you want the solution to ...
x^2 -5 = √(x -2)
This is conveniently reformulated to ...
x^2 -5 -√(x -2) = 0
so that we're seeking a zero of the function on the left.
The attached shows several iterations of the secant method. The function g is used to compute the x-intercept point on the line between (x1, f(x1)) and (x2, f(x2)). Then f(g( )) computes the function value at that x-intercept. We have used that to decide what the next interval limits (x1, x2) could be.
Our final guess at x is ...
x ≈ 2.367796 . . . . secant method
which gives an error less than 10^-5 between the left- and right-sides of the equation.

Additional comments
At the bottom of the attachment is the Newton's Method iterator. The nice thing about this graphing calculator is that it displays the result of computing h(x) even as the value of x is being typed. This means you can type what you see and achieve full calculator precision for the solution in basically one pass. This method gives x = 2.36779701571.
Some hand-held graphing calculators have a derivative function built-in, so it is practical to use them to perform Newton's method iteration in substantially the same way.
There are 14 girls and 12 boys in a class. What is the ratio of girls to students?
Answer:
7:13
Step-by-step explanation:
There are 14 girls and 12 boys, so there are 26 students in total. Since we are looking for the ratio of girls to students, the ratio will be 14:26. To simplify it, we will divide 14 and 26 by their greatest common factor: 2. We will get the ratio of 7:13.

Renee is creating a diagram to prove that a certain triangle is a right triangle. In her diagram, she uses three white quadrilaterals that are squares. Which diagram could be the one that Renee is creating
Answer:
Option D
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.
A right angled triangle is a triangle in which one of the angles is 90°. The side opposite the 90° is known as the hypotenuse while the remaining sides is known as the leg. Let us assume a right triangle with legs of a, b and a hypotenuse of c. Then using Pythagoras theorem:
c² = a² + b²
From the options, option d is the correct option.
For option D, the hypotenuse is c and one leg is a. Let x represent the second leg. Hence:
c² = a² + x²
x² = c² - a²
x = √(c² - a²)
Therefore the other leg would be √(c² - a²)
Briley has 347 marbles. Joey has 4 times as many as Briley. Carson has 799 fewer than Joey. How many marbles does Carson have?
Can somebody help me thank you? Show work please
Answer:
697 marbles
Step-by-step explanation:
We know:
Briley- 374 marbles
Joey- 374*4
Carson- (374*4)-799
Solve:
374*4= 1496 (This is how many Joey has)
1496-799= 697 (This is how many Carson has)

What is the simplest form of 15/60
Answer:
1/4
Step-by-step explanation:
Answer:
15/60 simplified equals:
1/4
Step-by-step explanation:
In the fraction 15/60, 15 is the numerator and 60 is the denominator.
When you ask "What is 15/60 simplified?", we assume you want to know how to simplify the numerator and denominator to their smallest values, while still keeping the same value of the fraction.
We do this by first finding the greatest common factor of 15 and 60, which is 15.
Then, we divide both 15 and 60 by the greatest common factor to get the following simplified fraction:
1/4

The polygons are similar. Find the values of
the variables. Write an equation and solve,
showing ALL the work.
Answer:
x=30° y=4
Step-by-step explanation:
[tex] \frac{y}{8} = \frac{2.5}{5} [/tex]
cross multiple
5y=8(2.5)
5y=20
divide 5 by 20
and you should y=4
since the polygons are similar x should have the same degrees as the bigger polygon
Answer: Y=4
Step-by-step explanation
Since the inside of a triangle is 180 degrees the 30 degrees plus the 90 degree corner minus the total inside degree so the other corner is 60 degrees. the dialation is 62.50 percent or .625 in decimal form which makes the vareable y equals 4 once you divide 2.5 by .625

suppose potatoes cost $0.99 per pound. complete the function rule c=? to describe the relationships between the total cost c and the number of pounds of potatoes p you buy.
Answer:
c=p*0.99
you gonna multiply the amt of patatoes by the cost of one to get the total like if you were buying 5 you would multiply 5 by 99 to get the total
P = $0.99
C = [tex]P * x[/tex]
[Note: x is how many pounds of potatoes you buy.]
Hope this helped, I'm not too good with relations.

Answer:
The average depth of five lakes is 229m. If none of the lakes is less than 194m deep then the greatest possible depth of one of these lakes in meters is,
Answer:
369
Step-by-step explanation:
* = Multiply
5*229=1145
Lakes * Average = Total Average Depth of Five Lakes
(1145-369)/4=194 (it worked)
4 is the other lakes, 369 would be considered the largest lake.
Answer is 369.
