================================================
Let's say you start off with $100. If you spend 3/4 of that, then you spend 75 dollars (because 75/100 = 3/4). Think of it like 75 cents = 3 quarters. If you spend 75 dollars out of 100 total, then you have 100-75 = 25 dollars left after the first round of spending.
If you spend 1/5th of what is left, then you spend $5 on the second round leaving 25-5 = 20 dollars left at the end of the day.
Total up what you spend for both rounds: 75+5 = 80, which divides over the original amount 100 to get 80/100 = 8/10 = 4/5
If you had 20 dollars at he end of the day, out of 100 initially, then 20/100 = 2/10 = 1/5 is the fraction of what you have left.
note how 4/5 and 1/5 add to 5/5 = 1.00 = 100%. This is because the amount you spend and the amount you have left over must add to 100% of all the money you started with

For a certain manufacturer only 4/5 of the item produced are not defective. If 2,000 items are manufactured in a month, how many are not defective?
Answer:
1600 items should not be defective
Step-by-step explanation:
To determine the number of items that are not defective, we multiply the number of items we have by the probability that they are not defective.
Not defective items = items * probability

Which points are on the graph of g(x)=(1/5)x
Select EACH CORRECT ANSWER
If a point is on the graph of the exponential equation then it should be true when you solve.
g(x) = (1/5)^x
y = (1/5)^x
1/125 = (1/5)^3
cbrt(1/125) = 1/5
.2 = 1/5
.2 = .2 YES
5 = (1/5)^-1
5 = 5 YES
1/25 = (1/5)^-2
-2root(1/25) = 1/5
5 = 1/5 NO
0 = (1/5)^1
0 = .2 NO
The correct answers are A and B.
This is about understanding input and output of a graph.
Correct Points are;
Option B; (-1, 5) and Option A; (3, 1/125)
The graph function is given as; g(x) = (1/5)ˣ
x is the input value which is on the x-axis
g(x) is the output value which is on the y-axis
This will follow a coordinate writing system of (x, y)
Option A; (3, 1/125) means that when x = 3, y = 1/125Let us put 3 for x in the function;
y = (1/5)³
y = 1/125
y = 1/125 corresponds to y = 1/125 and so it is correct.
Option B; (-1, 5) means that when x = -1, y = 5
Let us put -1 for x in the function;
y = (1/5)⁻¹
y = 5
y = 5 corresponds to y = 5 and so it is correct.
Option C; (-2, 1/25) means that when x = -2, y = 1/25Let us put 3 for x in the function;
y = (1/5)⁻²
y = 25
y = 1/25 doesn't correspond to y = 25 and so it is not correct.
Option D; (1, 0) means that when x = 1, y = 0Let us put 1 for x in the function;
y = (1/5)¹
y = 1/5
y = 0 doesn't correspond to y = 1/5 and so it is not correct.

what value of n makes the equation 4(0.5n -3) = n-0.25 (12 - 8n) true
Answer:
n = -9
Step-by-step explanation:
4(0.5n -3) = n-0.25 (12 - 8n)
First use the Distributive Law to expand the parentheses:-
2n - 12 = n - 3 + 2n
2n - 12 = 3n - 3
Subtract 2n from both sides:-
-12 = n - 3
Add 3 to both sides:-
-9 = n

a number divided by 70 has a quotient of 5 with the remainder of 14 what is the number and show your work
The number that divided by 70 results in a quotient of 5 with a remainder of 14 is 364. This can be calculated using the division algorithm formula 'Dividend = Divisor* Quotient + Remainder'.
Explanation:The division mentioned in the question can be represented using the division algorithm formula: Dividend = Divisor* Quotient + Remainder.
In your problem, the divisor is 70, the quotient is 5, and the remainder is 14. To find the dividend (which is the number you are trying to find), you simply substitute these values into the formula:
Dividend = 70*5 + 14
So, Dividend = 350 + 14 = 364.
Therefore, the number that when divided by 70, gives a quotient of 5 with the remainder of 14 is 364.

What is the lateral area of the pyramid?
We have two triangles with base 9ft and height 12.3ft and two triangles with base 11ft and height 11.9ft.
The formula of an area of a triangle:
[tex]A_\triangle=\dfrac{1}{2}bh[/tex]
Triangle #1:
b = 9ft and h = 12.3ft. Substitute:
[tex]A_1=\dfrac{1}{2}(9)(12.3)=55.35ft^2[/tex]
Triangle #2:
b = 11ft and h = 11.9ft. Substitute:
[tex]A_2=\dfrac{1}{2}(11)(11.9)=65.45ft^2[/tex]
The Lateral Area:
[tex]L.A.=2A_1+2_A2\\\\L.A.=2(55.35)+2(65.45)=241.6\ ft^2[/tex]
Answer: B. 241.6 ft².Answer: B
Step-by-step explanation:
The point here, on calculating the Lateral Area of a Pyramid is searching for Congruent Triangles. In a rectangular pyramid, we have four triangles, in the Lateral Area.
The basic formula for calculating the Area of any triangle is:
Δ[tex]=\frac{1}{2}*base*height[/tex]
So, let's plug it in the values for the 1st triangle:
Δ[tex]\frac{1}{2}* 11*11.9[/tex]
Δarea=[tex]65.45 ft^{2}[/tex]
For the second triangle (on the left):
Δ=[tex]\frac{1}{2}*9*12.3=\\ 55.35 ft²[/tex]
The base is a rectangle, this assures us the base of the other faces is also 9 ft and 11 ft.
So we can assume the other Triangle are congruent to Triangle 1 and 2.
The Lateral Area is the sum of all Pyramid's Triangles area:
55.35+55.35+65.45+65.45=241.6 ft²

how do you graph the linear equation y=9.5X
To graph the linear equation y= 9.5X, plot the y-intercept at point (0,0) due to the absence of +b. From there, move 1 unit to the right and 9.5 units up and place another point and do it several more times. Connect the points to form the line.
Explanation:To graph the linear equation y=9.5X, you need to understand that this is an equation of a line in the form y=mx+b, where m is the slope and b is the y-intercept. In this case, the slope is 9.5 and the y-intercept is 0 (since there is no +b following the 9.5).
Start by marking the y-intercept, which is at point (0,0), on your graph. The slope of 9.5 means that for every 1 unit you move to the right along the x-axis, you move up 9.5 units on the y-axis. So, from the y-intercept, you'd go over 1 and up 9.5, placing a point there. Do this several more times, then connect the points to form your line.
This line represents all solutions to the equation y=9.5X, meaning any point on the line satisfies the equation.

Final answer:
To graph y=9.5X, plot the y-intercept at (0,0), then use the slope to find another point by moving right 1 unit and up 9.5 units, plot this point, and draw a line through both points.
Explanation:
To graph the linear equation y=9.5X, you start by identifying the slope and y-intercept. In this case, the equation is already in the slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept. Since there's no plus or minus a number after 9.5X, the y-intercept is 0. The slope is 9.5, meaning for every increase of 1 unit in X, y increases by 9.5 units.
To graph this, you first plot the y-intercept at (0,0) on the vertical axis. Then, use the slope to find another point. From the y-intercept, move right 1 unit along the horizontal axis (increasing X by 1), and then move up 9.5 units on the vertical axis (increasing y by 9.5). Plot this second point. Finally, draw a straight line through both points, extending it in both directions. This line represents the equation y=9.5X.

On Monday, Harry had 75\%75% as many toys as Teddy did. On Tuesday, after Harry acquired 3232 more toys and Teddy acquired 15\%15% more than he had on Monday, Harry had as many toys as Teddy did. How many toys did Harry have on Monday?
Answer:
60
Step-by-step explanation:
We can first define the variables as hh for the number of Harry's toys on Monday and tt for the number of Teddy's toys on Monday.
We know that on Monday, Harry had 75\%75% as many toys as Teddy, so we can write the following equation:
\qquad h=0.75th=0.75t
Hint #2
When we add 3232 toys to Harry's collection, we get h+32h+32. We can also make an adjustment to Teddy's collection, as he acquired 15\%15% more. We can represent that as 1.15t1.15t, as we should add 15\%15% to 100\%100% to get a percent increase.
Now let's make an equation for Tuesday:
\qquad h+32=1.15th+32=1.15t
Hint #3
We also know that h=0.75th=0.75t from the first equation, so we can substitute that in.
\qquad 0.75t + 32 = 1.15t0.75t+32=1.15t
Let's solve by first subtracting 0.75t0.75t from both sides.
\qquad 32 = 0.4t32=0.4t
We can then divide by 0.40.4 to solve for tt, and when we do that, we find that t=80t=80.
Hint #4
Since t=80t=80, we must substitute it into another equation to find hh (the number of toys Harry had on Monday). Let's pick the first equation.
\qquad h=0.75th=0.75t
\qquad h=0.75(80) = 60h=0.75(80)=60
Hint #5
Harry had 60 toys on Monday.

(3x + 24):3x = 85:51 (3x + 24):85 = 3x:51 (3x + 24):51 = 3x:85 34:24 = 3x:51
Answer:
(A)
Step-by-step explanation:
The Postulate states that corresponding sides of similar triangles are in proportion.
We know that similar triangles are the triangle which have congruent triangles and and the corresponding sides are in proportion
Now in ΔSTP and ΔRPQ, corresponding sides are : (RP,TP); (RQ,TS) ; (PQ,PS)
So we have RP:TP = PQ:PS
TP= 51; RP= 85; PS = 3x; PQ = 3x+24
PQ : PS = RP : TP
3x+24 : 3x = 85 : 51
Hence 5 statement represents (A) equation
Answer: A) (3x + 24):3x = 85:51
