Answer:
Question 2: D. 604.9
Question 3: 80 oranges or 10/30 or 1/3
Step-by-step explanation:
For question 2:
Okay so, Hal has 5 3/4 bags of munch and each bag covers 105.2 area. We can take the whole number that is already there (5) and multiply it by 105.2 since it is the amount of 1 full bag. So: 5(105.2) is equal to 526.
Now we have to figure out how much 3/4 of a bag is. So take the amount of the full bag and divide it by the denominator (4). So: 105.2/4 is equal to 26.3. Now we know that for 1/4 of a bag it can cover 26.3. We are trying to find the 3/4 so take 1/4 and multiply it by 3 to get 3/4. We can do the same to the amount it is equal with: 26.3(3) and you get 78.9 as an amount of 3/4 of a bag of munch.
Now we add the 3/4 and 5 whole bags: 526.0+78.9=604.9
Our final answer is 604.9 so, option D is correct.
For question 3:
Basically taking all the given fractions: 1/5, 1/6 and 3/10. The lowest amount I can think of is multiplying the denominators to get 30 since they can all equal to 30. So multiply the denominator and numerator for each fraction:
1/5x6=6/30
1/6x5=5/30
3/10x3=9/30
Notice that the denominators are all equal to 30 so this allows us to now add them together.
6/30 + 5/30 + 9/30 = 20/30
Now we know that all together 20/30 is the already know fruits we can easily assume the 10/30 is the amount of oranges. We need to figure out the whole number and not the fraction so, take 240 and divide it by the denominator (30) and we get how much 1/30 is worth in a whole number. So: 240/30=8.
Now we know that 1/30=8 pieces of fruit. Take the 20/30 for already known fruit and we get 160. Take the 10/30 for oranges and we get: 10/30(8) is equal to 80 oranges.
So:
80 oranges
160 other known fruits
Basically 160=2/3 and 80=1/3.
We can check if this is true by:
2/3 (known fruit) and multiply the denominator and numerator by 10 to get 30:
2/3(10)= 20/30. We know this correct because 20/30 is the same as the known fruits fraction we got earlier. Next 1/3(10)=10/30 the 10/30 that was also equal to the amount of oranges.
Our final answer is 80 oranges or 10/30 or 1/3
I hope this helps:)

PLEASE HELPPPPPPPPPPP a nuclear disaster at Chernobyl in April 1986, approximately 12,600 kg of radioactive iodine-131 was released into the atmosphere. Iodine-131 is know to decay by half every 8 days. How many kilograms of iodine-131 remained after 24 days?
Answer:
1575 kg
Step-by-step explanation:
Decay rate formula =
N(t) = No(1/2)^t/t½
No = Initial amount = 12600kg
N(t) = Amount after time t
t½ = half life = 8 days
t = time = 24 days
N(24) = 12600 × (1/2)^24/8
1575kg

Find the points at which the tangent line is horizontal for the given interval. F(x)=cosx-sinx [0,2pi]
Answer:
[tex]x=\{\frac{3\pi}{4}, \frac{7\pi}{4}\}[/tex]
Step-by-step explanation:
For the tangent line to be horizontal, the derivative of the function at that point must be 0.
Thus, let’s first take the derivative of our function:
[tex]f ^\prime(x)=\frac{d}{dx}[\cos(x)-\sin(x)][/tex]
Differentiate:
[tex]f^\prime(x)=-\sin(x)-\cos(x)[/tex]
Now, let’s set our derivative equal to 0:
[tex]0=-\sin(x)-\cos(x)[/tex]
Let’s multiply everything by a negative:
[tex]0=\sin(x)+\cos(x)[/tex]
To solve for x, we can subtract sin(x) from both sides. This gives us:
[tex]\cos(x)=-\sin(x)[/tex]
Now, we can refer to the unit circle. First, remember that the only points for which cosine is equal to sine is at the π/4 points. That is, π/4, 3π/4, 5π/4 or 7π/4.
However, cosine is equal to negative sine. The only two quadrants for which cosine and sine are the same but also have opposite signs is QII and QIV.
Therefore, our answers are 3π/4 and 7π/4.
Jason is at the mall buying sno-cones for his friends. The function m = 5 − 1.25s represents the amount of money m he has left after s sno-cones. Find the zero value of this function by plotting points on the graph and finding the x-intercept.
Answer:
The zero value of the function occurs at s = 4
Step-by-step explanation:
The given function for the amount of money, m, Jason has left after buying s number of sno-cones for his friend is m = 5 - 1.25·s
Therefore, we have generated from Microsoft Excel the following data table used to plot the points on the graph
Number of Sno-cones [tex]{}[/tex] Amount of money left
0 [tex]{}[/tex] 5
1 [tex]{}[/tex] 3.75
2 [tex]{}[/tex] 2.5
3 [tex]{}[/tex] 1.25
4 [tex]{}[/tex] 0
Therefore, as seen from the above table, and from the attached graph, the zero value of the function occurs at the value where the amount of money left (y-coordinate value) is 0 which is at the value of s = 4.

monthly fee= $42
kilowatt per hour charge=$0.0953
let the number of hours be =x
let the expression be patterned after the model\
y=mx
here y=42
m=0.0953
We want to find x, the amount of electricity used
42=0.0953x
divide both sides by 0.0953 we have

Put the following equation of a line into slope-intercept form, simplifying all fractions. 20x-12y= 20x−12y= \,\,-108 −108
Answer:
well shiet
Step-by-step explanation:
y=5/3x+9 is the slope intercept form of the equation of line 20x-12y=-108
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The given equation is 20x-12y=-108
We need to write this equation in the form of slope intercept form.
To do this we have to isolate the y term
-12y=-108-20x
Now divide both sides by 12 and multiply with minus.
y=9+20/12x
y=9+5/3x
y=5/3x+9 is the required equation.
Hence, y=5/3x+9 is the slope intercept form of the equation of line 20x-12y=-108
