write 9.68 in expanded form
Answer:
9+0.6+0.08
Step-by-step explanation:
The given decimal number in expanded form is 9+0.6+0.08.
The given decimal number is 9.68.
What is expanded from of a decimal number?Unlike whole numbers, decimal numbers can also be written in the expanded form. For writing the decimals in expanded form, we multiply each of the decimal digits with increasing exponent values of (1/10).
Now, the expanded form of 9.68 is
9×1 + 6×1/10 + 8×1/100
= 9+0.6+0.08
= 9.68
Therefore, the given decimal number in expanded form is 9+0.6+0.08.

The range includes all integers between 0 and 12.5.
The range includes all numbers from 0 to 8.5.
The range includes all numbers from 0 to 12.5.
Answer:
The range includes all numbers from 5 to 12.5.
Step-by-step explanation:
The range is along y- axis and the domain is along x- axis.
Range is given in heights and domain is given in time seconds.
It can depicted that for t= 0 secs the ball is at 5 feet and so on .
Therefore the range is given by numbers from 5 to 12.5.
Whereas the domain is given by numbers 0 t0 8.5 seconds
The range is the values of 'y' and the domain is the values of 'x'. So, the range of the includes all numbers between 5 and 12.5 and the domain includes all numbers between 0 and 8.5.
Given :
A child tosses a baseball up into the air. On its way down, it gets caught in a tree for several seconds before falling back down to the ground.
The graph attached below shows the given scenario that "A child tosses a baseball up into the air. On its way down, it gets caught in a tree for several seconds before falling back down to the ground".
The y-axis shows the height of the ball in feet from the ground and the x-axis shows the time in seconds.
The range is the values of 'y' and the domain is the values of 'x'. So, the range of the includes all numbers between 5 and 12.5 and the domain includes all numbers between 0 and 8.5.
Therefore, the correct option is A) The range includes all numbers from 5 to 12.5.

What is the answer to this
2(x-5)-6=-18
x=___
Answer:
x= -1
Step-by-step explanation:
Distribute:2(x -5) -6 = -18
2x -10 -6 =-18
Subtract the numbers:2x -10 -6 =-18
2x -16 = -18
Add 16 to both sides of the equation:2x =16 += -18
2x -16 +16 = -18 +16
Simplify:2x = -2
Divide both sides of the equation by the same term:2x/2 = -2/2
Simplify:x=-1
Answer:x = -1
Andy is reading a novel. At 9:00AM, he has read 90 pages. At 12:00 PM, he has read 300 pages. What is Andy's average reading speed between 9:00AM and 12:00 PM? * 20 points
Answer: about 2 pages per minute
Answer:
75 pages an hour.
Step-by-step explanation:
y = 300/4x + 90
The question is asking for the slope
300/4 is the slope
300 pages in 4 hours.
We need to find out how many pages he can read per hour so we divide both numbers by 4.
300 ÷ 4 = 75
4 ÷ 4 = 1
He can read 75 pages per hour.

Topic : Composition of Functions - Worksheet 2 Using f(x) = 5x + 4 and g(x) = x - 3,find: 1. f(g(6)) 2. g(f(-7)) 3. f(f(8)) 4. g(f(x))
Answer:
[tex]f(g(6))=19[/tex][tex]g(f(-7))=-34[/tex][tex]f(f(8))=224[/tex][tex]g(f(x))=5x+1[/tex]Step-by-step explanation:
Considering the functions
[tex]f(x) = 5x + 4[/tex]
[tex]g(x) = x - 3[/tex]
Part 1)
Find
[tex]f(g(6))[/tex]We need to first dertermine [tex]g(6)[/tex]
[tex]g(x) = x - 3[/tex]
Putting x = 6
[tex]g(6) = 6-3=3[/tex]
Then
[tex]f(g(6))=f(3)=5(3)+4=15+4=19[/tex]
Hence,
[tex]f(g(6))=19[/tex]
Part 2)
Find
[tex]g(f(-7))[/tex]We need to first dertermine [tex]f(-7)[/tex]
[tex]f(x) = 5x + 4[/tex]
Putting x = -7
[tex]f(-7) = 5(-7)+4=-35+4=-31[/tex]
Then
[tex]g(f(-7))=g(-31)=(-31-3)=-34[/tex]
Hence,
[tex]g(f(-7))=-34[/tex]
Part 3)
Find
[tex]f(f(8))[/tex]We need to first dertermine [tex]f(8)[/tex]
Putting x = 8
[tex]f(8) = 5(8)+4=40+4=44[/tex]
Then
[tex]f(f(8))=f(44)=5(44)+4=220+4=224[/tex]
Hence,
[tex]f(f(8))=224[/tex]
Part 4)
Find
[tex]g(f(x))[/tex][tex]f(x) = 5x + 4[/tex]
[tex]g(f(x))=g(5x+4)[/tex]
[tex]=(5x+4)-3=5x+1[/tex]
Hence,
[tex]g(f(x))=5x+1[/tex]

Ross is shopping for mulch that costs $1.29 per cubic foot. During his first trip to the store, he bought 16.5 cubic feet. He needs another 4.5 cubic feet to complete his landscaping project. Which expression shows the total cost in dollars of the mulch?
A: 1.29⋅16.5⋅1.29⋅4.5
B: 1.29⋅16.5+4.5
C: 1.29(16.5+4.5)
D: 16.5(1.29+4.5)
Answer:
B
Step-by-step explanation:
Answer:
C. 1.29(16.5 + 4.5)
Step-by-step explanation:
In order to find the total cost he spent you would have to combine the amount of mulch he bought and then multiply the total amount of mulch by the amount it costs per foot. The only equation that represents this is C. The 16.5 and 4.5 cubic feet are combined to see how many cubic feet of mulch he bought, and then the value is multiple by 1.29, the cost of mulch per cubic foot.

A rectangular lawn 4m by 10m has a garden of uniform width added to one end. Then, along the combined side length of the lawn and garden , another garden is added, whose width is twice that of garden . The total area of the lawn and both gardens is 72 m2
Answer and explanation:
A rectangle's width is longer than the length
And so given a rectangular lawn 4m by 10m,
the width of the lawn= 10m
the length of the lawn= 4m
If a garden of uniform width is added, then garden's width = 10m
The garden of uniform width is added to the width side of the rectangular lawn( since along the combined side length of the lawn and garden, another garden is added)
The garden added to the combined side length of the lawn and garden has width twice that of the garden = 2*10= 20m
Given that total area of the lawn and two gardens = 72m²
Total area of lawn and 2 gardens(Area of rectangle(lawn+2 garden's)) is length * width
= 4*10+ 10*x+ 20*y=72
Therefore equation for total area of lawn and both gardens is 40+10x+20y=72
Where x is length of second garden attached to the width side of the lawn and y is length of the garden attached to the combined length side of the lawn and first garden
x can be solved
40+10x+20y=72
10x+20y=72-40
10x+20y=32
10x=32-20y
x=32-20y/10
Y can be solved
40+10x+20y=72
10x+20y=72-40
10x+20y=32
20y=32-10x
y=32-10x/20
Using the Equation, predict how much the Temperature change will be in 20 years since 2000.
Answer:
0.82° C
Step-by-step explanation:
To predict how much change the temperature will be in 20 years time since 2000, simply substitute x = 20 into the given equation, [tex] y = 0.52 + 0.015x [/tex]:
[tex] y = 0.52 + 0.015(20) [/tex]
[tex] y = 0.52 + 0.3 [/tex]
[tex] y = 0.82 [/tex]
✅The temperature change would be 0.82° C.
Given the function y=(0.84)t, determine whether the function represents growth or decay and identify the rate of change
Answer:
This function is a decay function and the rate of change is 0.16.
Step-by-step explanation:
We can tell this a decay function because the number in the parentheses is less than 1.
The "parent" function of a decay function is [tex]y = (1-b)^{x}[/tex], where x represents the t and b is the rate of change.
So that means 0.16 is b and 1 - 0.16 resulted in 0.84.
