Answer:
where is the question
Step-by-step explanation:
Answer:
Could be literally anything.
Step-by-step explanation:
"S" is a variable. All letters can be used, "S" has just been randomly picked. In mathematics, a variable is a symbol which functions as a placeholder for varying expression or quantities, and is often used to represent an arbitrary element of a set. In addition to numbers, variables are commonly used to represent vectors, matrices and functions.
the diagram shows a circle in a square 6cm calculate the shaded area take pi to 3.142
The question is incomplete (as there's no attachment to support the question).
However, I'll base my calculations base on the attached diagram to this solution.
Answer:
Shaded Area = 7.722 cm²
Step-by-step explanation:
Given.
Side of the square = 6cm
π = 3.142
Required:
Area of shaded region
First, the area of the square needs to be calculated.
Area of a square = Length * Length
Area = 6cm * 6cm
Area = 36cm²
Then we calculate the area of the circle.
To calculate this, we need to get the radius of the circle.
If the length of the sides of the square is 6 cm, then the diameter of the square is also 6 cm.
Now that we have the diameter, the radius can be calculated.
Radius, R = ½D (where R and D represent radius and diameter, respectively)
So,
R = ½ * 6 cm
R = 3cm
Area of a circle = πr²
Area = 3.142 * 3²
Are = 3.142 * 9
Area = 28.278 cm²
The shaded area is then calculated by subtracting the area of the circle from the area of the square.
Shaded Area = Area of Square - Area of Circle
Shaded Area = 36cm² - 28.278cm²
Shaded Area = 7.722cm²
Hence, the shaded area 7.722 cm²

What value of x makes this equation true?
0.6x – 5 = 0.1x + 7
Answer:
x=24,sorry if im wrong:/
Step-by-step explanation:
Answer:
24
Step-by-step explanation:
0.6x - 5 = 0.1x + 7
-0.1x -0.1x
0.5x - 5 = 7
+5 +5
0.5x = 12
(2)0.5x = 12(0.5)

Please help me. Due tonight.
Answer:
The sum of the interior angles of any triangle are equal to 180
therefore in this triangle, m<a+m<c+m<b=180
we know that 9x-26 and m<a are supplementary angles (meaning they add to 180) and therefore,
9x-26+a=180
9x+a=206
a=206-9x
(206-9x)+(2x-12)+(4x+43)=180
combine like terms
-3x+237=180
-3x=-57
x=19
if x=19 then we can substitue it in for c
4x+43=c
4(19)+43=c
c=119
Step-by-step explanation:
Find the value of x in the triangle shown below
Answer:
x = 50
Step-by-step explanation:
Since the 2 legs are congruent, both 7, then the triangle is isosceles and the 2 base angles are congruent, then
x = [tex]\frac{180-80}{2}[/tex] = [tex]\frac{100}{2}[/tex] = 50

Find the unit rate. Ryan can mow 3/5 of the yard in 2
hours. How much of the yard can Ryan mow in one hour?
Answer:
3/10 of the yard in one hour
Step-by-step explanation:
[tex]3/5(1/2)=3/10[/tex]
Answer:
3/10 of the yard.
Step-by-step explanation:
What we know:
Ryan can mow 3/5 of a yard in 2 hours.
What we need to know:
How much of the yard Ryan can mow in 1 hour, so the unit rate.
How do we do this:
It's simple if you think about it.
Just divide 3/5 by 2 (or multiply by 1/2)
3/5 * 1/2
3/(5*2)
3/10 of the yard can be mowed in one hour.
Nancy is trying to decide which cell phone plan would be the right one for her. She has
narrowed her choices down to two, Spirit and Horizon. Spirit (s) has a fixed fee of $20 and an
additional charge of 5 cents per minute. Horizon (h) has no fee and charges 15 cents per minute.
Write two equations that could be used to determine the total cost for each plan for 300 minutes?
A. s = 5x + 20
h=15x
B. s = 0.05x + 20
h = 0.15x
C. s = 15x
h = 5x + 20
D. s = 0.15x
h = 0.05x + 20

What is the equation in slope-intercept form of the line that passes through the point (12, 5) and is perpendicular to the line represented by y=34x−8?
Answer:
The equation in slope-intercept form of the line that passes through the point (12, 5) and is perpendicular to the line is:
[tex]y=-\frac{1}{34}x+\frac{91}{17}[/tex]Step-by-step explanation:
We know the slope-intercept form of the line equation
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
Given the line
[tex]y=34x-8[/tex]
comparing with the slope-intercept form of the line equation
The slope m = 34
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = 34
Thus, the slope of the the new perpendicular line = – 1/m = -1/34 = -1/34
Using the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values of slope = -1/35 and the point (12, 5)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-5=-\frac{1}{34}\left(x-12\right)[/tex]
Add 5 to both sides
[tex]y-5+5=-\frac{1}{34}\left(x-12\right)+5[/tex]
[tex]y=-\frac{1}{34}x+\frac{91}{17}[/tex]
Therefore, the equation in slope-intercept form of the line that passes through the point (12, 5) and is perpendicular to the line is:
[tex]y=-\frac{1}{34}x+\frac{91}{17}[/tex]apply properties of operations to write an equivalent expression. +++

Jim works in real estate sales. His annual salary is
$20,000 plus 2.5% of his home sales. What was the total
value of all homes he sold if his annual pay for the year
was $120,000?
Helppppp
Answer:
4,000,000
Step-by-step explanation:
We start by subtracting his salary (20k) from his annual income. That means he got 100,000 from selling homes.
So, what is 100,000 2.5% of?
I used the equation:
100,000 = .025x
with x being the value of all the homes.
Just divide and conquer, and you end up with a final answer of 4 Million
solve a package of 17 sliced apples $2.21.How much would a package with 25 sliced apples cost at the same price per slice?????solve pleaseee middle school
Answer:
$3.25
Step-by-step explanation:
So,
If a package of 17 sliced apples is $2.21, lets find out the price per apple.
2.21 / 17 = 0.13
so, the price per apple is $0.13
Now, we find the price of a package with 25 sliced apples.
0.13 x 25 = 3.25
So, the price of a package with 25 sliced apples is $3.25
Hope this helps!

If the volume of a cylinder is 900 cm squared with a height of 20 cm, what
is the diameter of the cylinder? Round to the hundredths.
Answer:
The diameter is 7.6 cm
Step-by-step explanation:
Mathematically, the volume of a cylinder can be calculated using the formula;
V = pi * r^2 * h
From the question;
V = 900
r = ?
h = 20
Substituting these values
900 = 3.142 * r^2 * 20
r^2 = (900)/(3.142 * 20)
r^2 = 14.32
r = √14.32
r = 3.78 cm
Mathematically, the diameter is 2 times the radius
We have this as;
2 * 3.78 = 7.6 cm
