Answer:
B
Step-by-step explanation:
If it is inscribed in the circle that means all four corners of the square are touching the circle
so therefore the diagonal of the square is the diameter of the circle
the side lengths of the square as you know is 7 units ([tex]\sqrt{49[/tex]) the length of the diagonal is [tex]7\sqrt{2}[/tex] heres how I know
If you cut the square in half through the centre diagonally you will get a right isosceles triangle, using the pythagorus theorum
[tex]7^2+7^2=C^2\\49+49=C^2\\98=C^2\\\sqrt{98}=C\\C=7\sqrt{x}[/tex]
Now we have the diameter
it's just half of that, so the answer is B
For a square inscribed in a circle, the length of the diagonal of the square equals the diameter of the circle. Given the area of the square is 49 units, the length of a side is 7 units, and thus the diagonal (or diameter of the circle) is 7√2 units. Therefore, the radius of the circle is half of the diameter, which is (7√2)/2 units.
Explanation:In this question, we need to determine the radius of a circle in which a square is inscribed. The square has an area of 49 square units. In a square inscribed in a circle, the diameter of the circle is equal to the diagonal of the square. Thus, if 'a' is the length of a side of the square, the length of the diagonal, which is the diameter of the circle, is 'a√2'.
Given that the area of the square is 49 units, 'a^2=49' or 'a=7' units. Therefore, 'a√2' = '7√2' units. As this is the diameter, the radius of the circle is half of the diameter thus, it equals '(7√2)/2' units. Which means option b '(7√2)/2' units is the correct answer.

£150 is divided between David, Mark & Henry so that David gets twice as much as Mark, and Mark gets three times as much as Henry. How much does David get?
Answer:
David receives £90
Step-by-step explanation:
Let David's share be D
Let Mark's share be M
Let Henry's share be H
From the question, we obtained the following data:
David gets twice as much as Mark i.e
D = 2M
M = D/2
Mark gets three times as much as Henry i.e
M = 3H
H = M/3
H = (D/2) /3
H = D/6
The sum of their shares is £150 i.e
D + M + H = 150
D + D/2 + D/6 = 150
Multiply through by 6 to clear the fraction
6D + 3D + D = 900
10D = 900
Divide both side by the coefficient of D i.e 10
D = 900/10
D = 90
Therefore, David receives £90

What is the solution of the system of equations?
5x + 4y = -22
2x – 3y = 5
Answer:
y = 3
x =7
Step-by-step explanation:
to solve this system of equations using substitution method we say, let
5x + 4y = -22 .................... equation 1
2x – 3y = 5...................... equation 2
from equation 2
2x - 3y = 5
2x = 5 + 3y
divide both sides by 2
we have;
2x/2 = (5+3y)/2
x =(5+3y)/2................................ equation 3
put x = (5+3y)/2 in equation 1
5x + 4y = -22 .................... equation 1
5(5+3y)/2 + 4y = -22
(25 + 15y)/2 + 4y = -22
multiply through by 2
25 + 15y + 8y = -44
25 + 23y = -44
collect the like terms
23y = -44 - 25
23y = -69
divide both sides by 23
23y/23 = -69/23
y = 3
put the value of y= 3 into equation 3
x =(5+3y)/2................................ equation 3
x = (5+3(3)]/2
x = 5+9/2
x =14/2
x =7

Solve for x: 4/7 = x-1/12
To solve for x in the equation 4/7 = x-1/12, combine the fractions, cross multiply, and solve to find x=3 and x=-7.
Explanation:Solve for x: 4/7 = x-1/12
To solve for x, first combine the fractions on the right side: 4/7 = (12x - 1)/12. Then, cross multiply to get 12*4 = 7*(12x - 1). Solve for x to find x=3 and x=-7.
By substituting these values back into the original equation, which is x is equal to (12x-1)/12, you can verify these solutions.

A
A) 752 boxes
B) 757 boxes
C
C) 799 boxes
D) 858 boxes
In an 812-hour day, a cereal company that packages 305.50 lbs of cereal an hour would package approximately 76,331 boxes of cereal, given each box contains 3.25 lbs of cereal. The provided options in the question do not match this result.
The subject of this question is Mathematics, specifically division used in a real-world context regarding a cereal company's packaging process. To find the number of cereal boxes produced in an 812-hour day, we need to divide the total weight of cereal packed in a day by the weight of cereal in each box.
Firstly, we find out the total amount of cereal produced by multiplying the hourly rate by the number of hours. This will give us: 305.50 lbs/hour x 812 hours = 248,071 lbs.
Next, we divide the total amount of cereal by the weight of cereal in each box to find the number of boxes. Therefore, 248,071 lbs ÷ 3.25 lbs/box = 76,331 boxes.
None of the options (A) 752 boxes, (B) 757 boxes, (C) 799 boxes, (D) 858 boxes match our result. There might be an error in the question or the choices provided.

You've been given a twenty dollar bill that you need to break into smaller bills and coins in order to make change. You break it into three (3) five-dollar bills, and three (3) one-dollar bills. How many quarters do you need to complete the conversion?
Answer:
8 quarters
Step-by-step explanation:
You need to break the $20 into smaller bills. The smaller bills value has to be equal to $20. So far you have three $5 bills and three 1$ bills, so the current value is 3*$5 + 3*$1= $18
The value you need to add more will be $20- $18= $2
You need to add $2 more value to the smaller bills and you want to do it using quarters($0.25). The number of the quarter you need will be: $2/ $0.25= 8 quarters
Let's start by calculating the total value of the five-dollar bills and one-dollar bills:
You have 3 five-dollar bills, and each is worth $5, so:
3 five-dollar bills × $5 per bill = $15
You also have 3 one-dollar bills, and each is worth $1, so:
3 one-dollar bills × $1 per bill = $3
Now, let's add the value of the five-dollar bills and one-dollar bills together:
$15 (from five-dollar bills) + $3 (from one-dollar bills) = $18
You started with a twenty-dollar bill, which is worth $20, so we subtract the total value of the bills you have from $20 to find out how much is left to reach $20:
$20 (initial amount) − $18 (value of bills) = $2
You need to make up this remaining $2 with quarters. Since each quarter is worth $0.25 (25 cents), we divide the remaining amount by the value of each quarter to find out how many quarters you need:
$2 ÷ $0.25 per quarter = 8 quarters
Therefore, you need 8 quarters to complete the conversion to $20.

The graph of the function passes through the point (2, 1), and y increases by 4
when x increases by 1.
Answer:
[tex]y=4x-7[/tex]
The graph in the attached figure
Step-by-step explanation:
In this problem I will assume the the function is linear
we have the point (2,1)
we know that
y increases by 4 when x increases by 1
Remember that the formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
so
The slope of the linear function is
[tex]m=\frac{4}{1}[/tex]
Find the equation of the line in point slope form
[tex]y-y1=m(x-x1)[/tex]
substitute
[tex]y-1=4(x-2)[/tex]
Convert to slope intercept form
Isolate the variable y
[tex]y-1=4x-8\\y=4x-8+1\\y=4x-7[/tex]
see the attached figure to better understand the problem
The question pertains to the characteristics of a linear function whose graph passes through the point (2, 1) with a slope of +4, indicating an increase of 4 in y for every increase of 1 in x. The line's positive slope suggests the graph rises as the x-value increases. The equation of the line is y=4x-7.
Explanation:The student is asking a question about the characteristics of a linear function based on its graph. Specifically, since the graph passes through the point (2, 1) and the value of y increases by 4 when x increases by 1, we can conclude that the slope of the line is +4. This is because the slope of a line represents the change in y divided by the change in x. Given that the slope is positive, this line will show an upward trend on the graph as the x-value increases, much like other graphs with a positive slope.
To find the equation of the line, we start by using the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. We use the point (2, 1) and the slope 4 to solve for b. The process is as follows:
1 = 4(2) + b
1 = 8 + b
b = -7
Therefore, the equation of the function is y = 4x - 7.
