What's happening in the real world?
As he cooks on the barbecue, the weight of the tank goes down because some of the propane is getting used up.
Given that is happening, the graph showing that has to start with a lot in it and slowly decrease.
A shows the exact opposite. As he cooks, he gets more weight in the tank, not less.
B says that over time, there is no change in weight of the tank. How can that be? The tank ought to get lighter. The answer is not B
C is the correct answer.

The table shows the results of randomly selecting a colored cube from a bag 80 times. The cube was returned to the bag after each selection.
Based on these results, what is the expected probability of randomly selecting a red cube from the bag in one attempt?
A) 0.20
B) 0.04
C) 0.24
D) 0.30
Can someone help me with this
Step-by-step explanation:
Look at the top problem first.
There is only one place where you see both numbers of the ratio. It is the last column. 56/14 = 4. That means that every number on the top line has to be 4 times the number below it.
14/3.5
28/7
42/10.5
Now look at the second problem. You have 44.4 and 1332.
1332/44.4 = 30
The bottom line is 30 times greater than the line above.
88.8/2664
22.2/666
11.1/333

Write this number in scientific notation.
Thank you!
Answer:To write the number 0.0000149 in scientific notation, we need to express it as a number between 1 and 10 multiplied by a power of 10.
First, we move the decimal point to the right until there is only one non-zero digit to the left of the decimal point, which gives us:
1.49 × 10^-5
Since we moved the decimal point 5 places to the right, the exponent of 10 is negative 5.
Therefore, the scientific notation of 0.0000149 is 1.49 × 10^-5.
Step-by-step explanation:
Answer:
1.49×10^-5
Step-by-step explanation:
0.0000149=1.49×10^-5
it's to the power of -5 because it's a decimal number not a whole number
cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide
Answer:
To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.
Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).
Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).
To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
First, find out how much stickers you can put on the long side:
12/3 = 4
Next, find out how much stickers you can put on the wide side:
8/2 = 4
Lastly, calculate them together:
4x4=16
So the answer is 16.

First, I remember IXL and it makes people rage, haha.
So, the two smaller sides are your "legs" and are the "a" and "b" in \(a^2+b^2=c^2\)
2 squared is 4, and 9 squared is 81
4+81=85

Hi my lovely people!
Today's question is math!
There are 2 screenshots below of my work!

Answer:
Part 1:
A - (4,9)
B - (6,3)
C - (1,3)
D - (8,7)
E - (8,9)
To know where to put the dots on the graph, use the coordinates you've just been given:
Example: (4,8)
Move to the 4 on the x-axis (the line on the bottom going horizontal)
Then, move up 8 units (up to the 8 on the y-axis)
Place the point at that spot.
Part 2:
A - (1,2)
B - (2,4)
C - (3,6)
D - (4,8)
Derek decorates 10 cookies in 5 minutes. We know he took 5 minutes to decorate 10 cookies because in the table, the x-axis is told to us that it represents the time it takes. Since the x coordinate is 5 in the point (5,10) and the y coordinate is 10, we can safely say that it took Derek 5 minutes to decorate 10 cookies.
Kenneth graphed a system of equations.
Kenneth says the system has no solution

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Answer:
Step-by-step explanation:
a = \(\sqrt{12^2 -9^2} = \sqrt{144-81} = \sqrt{63}\)
We use the minus because we are searching a leg.
A leg is always shorter than the hypotenuse
Answer:
a = 7.9 or a = √63
Step-by-step explanation:
a² + b² = c²
(The two shorter sides of a triangle are always a and b while the longer side will always be c)
So, here the longer side of this triangle is 12 and the shorter sides are 9 and a (unknown).
The equation is: a² + 9² = 12²
But to find the value of a, the formula will be 12² - 9² = a²
12² - 9² = a²
144 - 81 = a²
63 = a²
the square root of 63 = 7.9 so that means a = 7.9
An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $6100 and his stock in Company B was worth $6480. The stock in Company A has decreased 2% since last year and the stock in Company B has decreased 10%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Investment in Company A by investor = $6100
Investment in Company B by investor = $6480
The decrease in value of the stock of company A is 2%
The decrease in value of the stock of company B is 10%
Value of wealth that investor lost in company A = 6100× 2/100
= 61×2
= $122
The decline in the value of the stock of company B = 6480×10/100
= 648×1/1
= $648
The total decline in the wealth of the investor= 122+648
= $770
The combined wealth of investor in both companies= 6100+6480
= $12580
Percentage of decline in the stock account of investor= 770×100/12580
= 77000/12580
= 6.1%
The total percentage decline in investor's stock account is 6.1%
