Answer:
area of circle having radius 3
is πr²=π*3²=9π square units
area of circle having radius 2
=πr²=π×2²=4π square units
again
area of big circle having radius [3+2]=5 units
=πr²=π×5²=25π square units
Now
area of shaded region=25π-4π-9π=12π or 37.7square units.
Answer:
37.7 sq units
Step-by-step explanation:
Find area if entire region then subtract out each smaller circle
Diameter of entire circle would be 3(2)+2(2) which is 10 so radius is 5
Area of entire region = 25π
Area of circle one = 9π
Area of circle two = 4π
Area of shaded region = 25π - 13π which is 12π or 37.7
what divided by 5/6 equals 3/5
Answer:
let the decided no. be x
Now
[tex] \frac{5}{6} \times \frac{1}{x} = \frac{3}{5} [/tex]
[tex]5 \times 5 = 3 \times 6x[/tex]
[tex]x = \frac{25}{18} or1 \frac{7}{18} [/tex]
is a required answer.
when
no. divided by 5/6 equals 5/3
now
[tex] \frac{5}{6} \times \frac{1}{x} = \frac{5}{3} [/tex]
[tex]5 \times 3 = 5 \times 6x[/tex]
[tex]x = \frac{15}{30} [/tex]
[tex]x = \frac{1}{2} [/tex]is a required answer.
The length of a rectangle is 5m greater than its width and its area is 6m2. Find its dimensions.
[Hint: draw and label a picture]
Answer:
Width = 1 m and length = 6 m
Step-by-step explanation:
Let b is the width of the rectangle.
Length = 5+b
The area of the rectangle, A = 6 m²
We need to find the dimensions of the rectangle. We know that, the area of a rectangle is given by :
A = lb
[tex]6=(5+b)b\\\\6=5b+b^2\\\\b=-6, b=1[/tex]
Width of the rectangle = 1 m
Length of the rectangle = 5+b = 6 m
Hence, this is the required solution.

Rearrange 3x - 6y = -2 to the form y=mx + c
3x - 6y = -2
-6y = -3x - 2, divide through by -1
6y = 3x + 2, divide through by 6
y = 3x/6 + 2/6
y = x/2 + 1/3
Answer:
y = 1/2x - 1/3
Step-by-step explanation:
subtract 3x from each side first to get:
-6y = -3x - 2
divide each side by -6 to get:
y = 3/6x - 2/6
simplify:
y = 1/2x + 1/3
Which graph represents the following piecewise defined function?
Answer:
A on Edge
Step-by-step explanation:
Just took the test and got a 100
The graph that represents the following piecewise defined function is of f(x) = x; x <-2 , -2; -2 < or = to x < or = to 1, x-3; x> or = to 1 is the first graph (Image attached)
What is a piecewise function?A piecewise function is known to be a function that has been formed from pieces of a lot of functions over a lot of intervals.
An example, we can say a piecewise function f(x) where f(x) = -7 when -7 < x ≤ -4, f(x) = 4 when -4 < x ≤ -1, and f(x) = -5 when -1 <x ≤ 7.

Becky found a tennis ball outside a tennis court. She picked up the ball and threw it over the fence into
the court. The path of the tennis ball can be represented by h = -16t2 + 80t, where h represents the
height of the tennis ball in feet and t represents the time in seconds.
31. Find the maximum height of the tennis ball.
32. How long will it take for the tennis ball to hit the ground?
Answer:
31). Maximum height = 100 feet
32). Time to hit the ground = 5 seconds
Step-by-step explanation:
31). Equation modeling the height 'h' of the ball is,
h = -16t² + 80t
For the maximum height of the ball,
Find the derivative of 'h' with respect to time 't' and equate it to zero.
[tex]\frac{dh}{dt}=\frac{d}{dt}(-16t^2+80t)[/tex]
[tex]=-32t+80[/tex]
[tex]\frac{dh}{dt}=0[/tex]
[tex]-32t+80=0[/tex]
[tex]t=\frac{80}{32}[/tex]
[tex]t=2.5[/tex] seconds
That means after 2.5 seconds ball will reach the maximum height.
By substituting [tex]t=2.5[/tex] in the equation,
[tex]h=-16(2.5)^2+80(2.5)[/tex]
[tex]h=100[/tex] feet
Therefore, maximum height achieved by the ball is 100 feet.
32). If the ball follows the parabolic path,
Time taken by the ball to reach the maximum height = Time taken by the ball to come back to the ground from the maximum height.
Time taken by the ball to hit the ground = 2(2.5) = 5 seconds

Step-by-step explanation:
We need to find the additive inverse of the given numbers.
For finding it we may simply out -1 as multiplication in front of the terms .SOLUTION 1 :-
→ 3/-7 - 11/21
→ -3/7 -11/21
→ 3×-3 - 11 /21
→ -9-11/21
→ -20/21
SOLUTION 2 :-
→ 9/5 ÷ 7/5
→ 9/5 × 5/7
→ 9/7
→ Product of nos . = -20/21 × -9/7
→ Ans = 180/147

Tom has some marbles in two bags. In one bag he has 3 yellow, 2 green and 1 red marble. In the other bag he has 3 yellow, 3 green and 3 red marbles. If Tom takes one marble out of each bag, how probable is it that neither one is yellow? Include a chart of all the data you have.
Answer:
1 / 3
Step-by-step explanation:
Bag 1 :
Yellow = 3
Green = 2
Red = 1
Total = 3 + 2 +1 = 6
Bag 2 :
Yellow = 3
Green = 3
Red = 3
Total = 3 + 3 + 3 = 9
P(not yellow from bag 1) = (green + red) / total = 3 /6 = 1/2
P(not yellow from bag 2) = (green + red) / total = 6/9 = 2 /3
P(neither is yellow) = 1/2 * 2/3 = 2 / 6 = 1/3

Amari claims that a rectangle is sometimes a parallelogram but a parallelogram is always a
rectangle. Is she correct? Explain if you agree or disagree with her and why.
Answer:
The statement is false.
Step-by-step explanation:
A parallelogram is a figure of four sides, such that opposite sides are parallel
A rectangle is a four-sided figure such that all internal angles are 90°
Here, the statement is:
"A rectangle is sometimes a parallelogram but a parallelogram is always a
rectangle."
Here if we found a parallelogram that is not a rectangle, then that is enough to prove that the statement is false.
The counterexample is a rhombus, which is a parallelogram that has two internal angles smaller than 90° and two internal angles larger than 90°, then this parallelogram is not a rectangle, then the statement is false.
The correct statement would be:
"A parallelogram is sometimes a rectangle, but a rectangle is always a parallelogram"

(05.03 MC) Ivy has borrowed 150 songs from her friend. She plans to download an equal number of songs on her music player each week for 5 weeks. The graph shows the number of songs left to download, y, for a certain number of weeks, x:
A graph titled Song Downloading shows Number of Weeks on x-axis and Number of Songs Left to Download on y-axis. The x-axis scale is shown from 0 to 5 at increments of 1, and the y-axis scale is shown from 0 to 210 at increments of 30. A straight line joins the ordered pairs 0, 150 and 1, 120 and 2, 90 and 3, 60 and 4, 30 and 5, 0.
Part A: What is the rate of change and initial value of the function represented by the graph, and what do they represent in this scenario? Show your work to find the rate of change and initial value. (6 points)
Part B: Write an equation in slope-intercept form to model the relationship between x and y. (4 points)
Answer:
See below.
Step-by-step explanation:
A) The rate of change would be dividing the number of songs wanted (150) by the number of weeks downloading (5).
150/5 = 30
As the total quantity wanted is becoming less every week the rate of change would be negative so it becomes -30.
The initial value is 150, which is the total number of songs she wants.
B)
We’ll use A(0, 150), and B(1, 120)
calculate the slope:
m = (y2- y1)/(x2 - x1) = (120 - 150)/(1 - 0)
(in other words: delta y / delta x)
m = -30
Finally, use the line equation in form point-slope:
y - y1 = m(x - x1)
y - 150 = -30(x - 0)
y = -30x + 150
