A square fits exactly inside a circle with each of its vertices being on the circumference of the circle.
The square has sides of length x cm.
The area of the circle is 56cm squared.
Work out value of x.
Give answer correct to 3 significant figures.
Answer:
The side of the square is 5.971 cm
Step-by-step explanation:
If the square fits the circle exactly, then its diagonal is equal to the diameter of the circle. Since the side of the square has a length of [tex]x[/tex] cm, then it's diagonal have the length of [tex]x\sqrt2[/tex] cm. Using the circle's area we can find the diagonal of the square, as shown below:
[tex]area = \pi*r^2\\56 = pi*r^2\\r^2 = \frac{56}{\pi}\\r = \sqrt{\frac{56}{\pi}}\\r = 4.222[/tex]
Since the diameter of the circle is the same as the diagonal of the square, then:
[tex]x\sqrt{2} = 2*r \\x = \frac{2*r}{\sqrt{2}}\\x = \frac{2*4.222}{\sqrt{2}}\\x = 5.971[/tex]
The side of the square is 5.971 cm

Answer:
x = [tex]\frac{ab}{c+a}[/tex]
Step-by-step explanation:
a(b-x) = cx
ab - ax = cx
ab = cx + ax
ab = x (c + a)
divide both sides by (c + a) for x to stand alone
x = ab/ c + a

Which line on the graph below has a slope of zero? On a coordinate plane, line Q is horizontal, line P has a positive slope, line R is vertical, and line S has a negative slope.
Answer:
line q because it just is
Step-by-step explanation:
The line that has zero slope is horizontal in the coordinate plane. the correct option is (a).
What is the slope of straight line?The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference. The negative slope indicates the rate of decrease while the positive shows the rate of increase.
The given options can be analysed one by one as follows,
(a) A horizontal line on a coordinate plane is parallel to x axis.
The angle the line makes with x axis is zero which implies the slope is also zero.
(b)The line in the given case has some positive value of slope.
(c) A vertical line makes right angle with x axis.
Thus, the slope is tan(90°) = ∞,.
(d) The line in the given case has some negative value of slope.
Hence, the horizontal line will have zero slope.

Aisha reduced the size of her square driveway. She made one side 10 feet shorter and the other side 15 feet shorter. The smaller rectangular driveway will have an area of no more than 800 square feet.
Complete Question:
Aisha reduced the size of her square driveway. she made one side 10 feet shorter and the other side 15 feet shorter. the smaller rectangular driveway will have an area of no more than 800 square feet. write an inequality to represent the area of the smaller driveway.
Answer:
The inequality that represents the area of the smaller drive way is [tex]x(x-25) \leq 650[/tex]
Step-by-step explanation:
Let the original length of the sides of Aisha's square driveway be = x
She made one side 10 ft short, i.e. (x - 10) ft
She made the other side 15 ft short, i.e. (x - 15) ft
Since the sides are no longer equal, the driveway is now a rectangle
The question states that the smaller rectangular driveway will have an area of no more than 800 square feet
Area of a rectangle = length * Breadth
Area = (x - 10)*(x - 15)
[tex]Area = x^{2} - 15x - 10x + 150\\Area = x^{2} - 25x + 150[/tex]
Area ≤ 800
[tex]x^{2} - 25x + 150 \leq 800\\ x^{2} - 25x - 650\leq 0\\x(x-25) \leq 650[/tex]
Solving the above, x = 40.9 or -15.9
Since the length of a square cannot be negative, x = 40.9 ft
Answer:
(x-10)·(x-15)≤800

Joaquin used 1-3/6 cups of apple juice and 1-4/6 cups of orange juice in a recipe for punch. How much juice did Joaquin use?Solve this problem any way you choose.
Answer:
The answer is 3 and 1/6 cups.
Step-by-step explanation:
If Joaquin used 1 and 3/6 cups of apple juice and 1 and 4/6 cups of orange juice for the punch, there is a total of 2 cups and the fractions can be added as their denominators are the same.
3/6 + 4/6 = 7/6 cups
So the total juice in the punch is 3 and 1/6 cups.

In ΔLMN, the measure of ∠N=90°, ML = 97, NM = 65, and LN = 72. What ratio represents the tangent of ∠L?
Answer:
tan ∠L = 65/72
Step-by-step explanation:
The tangent ratio is:
tan of angle x = opposite/adjacent
Looking from the perspective of angle L, find the opposite side.
This side is MN, measuring 65 units.
opposite = 65
Now let's find the adjacent side.
This side is LN, measuring 72 units.
adjacent = 72
Therefore, the tangent ratio of angle L is 65/72.
Answer:
65/72

Answer: The diameter of Pool A is 7.32 meters. So, the diameter of Pool B is greater, and the circumference is greater by 0.56 meters.
Step-by-step explanation:
The diameter of a circle is double its radius.
Pool A has a radius of 12 feet - double that would be 24 feet, its diameter.
Next, convert this to meters:
[tex]24 * \frac{0.305}{1} = 7.32[/tex]
The diameter of pool A is 7.32 meters.
The diameter of pool B is 7.5 meters.
The diameter of pool B is greater.
You can calculate the circumference of a circle by using this formula:
[tex]C = 2\pi r[/tex], where r is the radius.
Divide 7.5 by 2 to get your radius of Pool B, which is 3.75, and solve for C:
[tex]C = 7.5\pi \\\\C = 23.561[/tex]
Rounding to the nearest hundredth, the circumference for pool B is 23.56 meters.
Do the same thing for pool A:
[tex]C = 7.32\pi \\\\C = 22.996[/tex]
Circumference for pool A rounds to 23 meters.
Answer:
the diameter of pool a is 24. so, the diameter of pool b, is greater, and idk the rest

13 sin(2x) - 3 = 3
Answer:
The answer is A
Step-by-step explanation:
Answer:
0.24+n*pi and 1.33+n*pi
Step-by-step explanation:
First you add three to both sides to get:
13sin(2x)=6
Then you divide by thirteen to both sides to get:
sin(2x)= 6/13
Next, you use a calculator to perform the inverse of sine to both sides, which is arcsin, and cancels out the sin.
arcsin(sin(2x))= arcsin(6/13) -> 2x= arcsin(6/13)
Arcsin(6/13)= approximately 0.48. But besides 0.48, there is another solution, because the y value of 6/13 can have two possible x values, both in quadrant one and two. We found the quadrant one value. The quadrant two value is just pi-0.48=2.66.
So, if we add two pi (360 degrees) to both of these solutions for n amount of times, then on a graph, we would end up on the same point every time. Each of those revolutions around the graph is one solution. These are the solutions:
2x= 0.48+n*2pi -> 0.24+n*pi
2x=2.66+n*2pi -> 1.33+n*pi

Which equation has no solution?
Answer:
B. 5 + 2(3+2x) = x + 3(x+1)
Step-by-step explanation:
5 + 2(3+2x) = x + 3(x+1)
5 + 6 + 4x = x + 3x + 3
11 + 4x = 4x + 3
4x - 4x = 3 - 11
0 = - 8, which is absurd.
Hence the equation 5 + 2(3+2x) = x + 3(x+1) has no solution.
find the point that lies on the line described by the equation below. y - 3 = 3 (x - 9)
Answer: D
Step-by-step explanation: (9,3) is the given point in the equation where y-y1=m(x-x1)
Answer:
D. (9, 3)
Step-by-step explanation:
You can solve figure this out by plugging in the coordinates. The best guess would be that the answer is "D," and we can check:
y - 3 = 3(x - 9)
3 - 3 = 3(9 - 9)
0 = 3(0)
0 = 0
Since the answers match, answer "D," is correct.

Corrected Question
The blueprint for the Moreno Moreno's living room has a scale of 2 inches equals 7 feet.The family wants to use a scale of 1 inch equals = 6 feet. What is the width of the living room on the new blueprint? A rectangle is labeled width = 12 inches.
Answer:
7 Inch
Step-by-step explanation:
The width of the room on the old blueprint = 12 Inches
Scale on the old blueprint:
2 inches = 7 feet.
Therefore: 1 Inch =7/2 feet
12 Inches =12 X 7/2 feet =42 feet
The actual width of the room is 42 feet.
Scale on the new blueprint
1 inch equals = 6 feet; which we can reorder as:
6 feet=1 inch
1 feet =1/6 Inch
Therefore:
42 feet = 42 x 1/6 Inch =7 Inch
Thus, the width of the living room on the new blueprint is 7 Inch.
what is the circumference of a circle witha radius of 4 in
25.12 in or 8π
Step-by-step explanation:
Since you didn't specify whether or not to leave pi or to make it be 3.14, I did both.
The formula for the circumference of a circle is...
[tex]C=2\pi r[/tex]
So...
[tex]C=2*3.14*4[/tex]
C = 25.12 in
If you want to leave pi...
[tex]C=2*\pi *4[/tex]
C = 8π
