what is the decimal form of 100/3 100/5 and 100/6? determine whether each repeats or terminates
to know the decimal form, just make the division
Step 1
[tex]\begin{gathered} \frac{100}{3} \\ \frac{100}{3}=100\text{ divide by 3} \\ \text{operate} \\ 100\text{ divide by 3 = 33 and 1 to left} \\ \end{gathered}[/tex]every time you divide you will have a residual number (1),

Find the slope of a line that contains the points A(−8,3)and B(−4,6)
Answer:
You have to use the formula:
(y-y1)/(y2-y1) =(x-x1)/(x2-x1). So draw a graph and place the points A and B on the Graph, then put the numbers in the formula. A(-8=x1, 3= y1), B(-4=x2,6=y2). You will get the formula and consequently the slope.

"Twice a number, increased by three times the difference of the number and 3 is 11"
Answer:
number is 4
Step-by-step explanation:
let n be the number then twice the number is 2n and the difference of the number and 3 is n - 3 , so
2n + 3(n - 3) = 11 ← distribute parenthesis and simplify left side
2n + 3n - 9 = 11
5n - 9 = 11 ( add 9 to both sides )
5n = 20 ( divide both sides by 5 )
n = 4
As a check
twice the number is 2 × 4 = 8
increased by 3 times the difference of n and 3 is
8 + 3(4 - 3) = 8 + 3(1) = 8 + 3 = 11 ← Correct
Translation of a PointWhat is the image point of (5,-5) after a translation right 2 units and up 3 units?Submit Answer
ANSWER
(7, -2)
EXPLANATION
We want to know the image point after a translation.
A translation is basically a shift in the position of the object.
The object point is (5, -5) and it translates 2 units right and 3 units up.
That means there is a shift +2 units on the x axis and +3 units on the y axis.
Therefore, the image point is:
(5 + 2, -5 + 3)
= (7, -2)
That is the image point.

Cylinder 1 4 cm om Cylinder 2 on Fill in each box to complete the following statements. 4 cm To the nearest tenth, the volume of Cylinder 1 is To the nearest tenth, the volume of Cylinder 2 is
Without doing any calculations, do you think Cylinder 1 and Cylinder 2 will have the same volume?
No, because the radius are different. In the first cylinder the radius is 4cm and 7cm in the second one.
The volume V of a cylinder is given by
[tex]V=\pi r^2h[/tex]where Pi is 3.1416, r is the radius and h is the height.
Then, the volume of cylinder 1 is
[tex]V_1=(3.1416)(4^2)(7)cm^3[/tex]which gives
[tex]V_1=351.9cm^3[/tex]Now, the volume of cylinder 2 is
[tex]V_2=(3.1416)(7^2)(4)[/tex]which gives
[tex]V_1=615.8cm^3[/tex]Therefore, the answer are

R y= x(x, y) —> (y, x) The rule for a reflection over the y -axis is (x,y)→(−x,y) After reflection we get DGFE.
How can coordinates be determined after reflection?When a point is reflected across the line y = x, the x and y coordinates move.Similarly, when a point is mirrored across the line y = -x, the x and y coordinates are negated. As a result, the reflection of the point (x, y) across the line y = x is (y, x)Students investigate reflections over the x- and y-axes in this exercise, with a focus on the relationship between the coordinates of the pre-image and the image. As an extension, students can try to reflect a pre-image across the line y = x.A translation would be a transformation that moves all of the points in a figure by the same amount in the same direction. For example, this transformation shifts the parallelogram 5 units to the right and 3 units up. It is written as ( x , y ) → ( x + 5 , y + 3 )To graph is to create a diagram that depicts a relationship between two or more things. A graph can be made by drawing a series of bars on graph paper.

Answer:
P=22 a=30
Step-by-step explanation:
a= L x W

Perimeter is adding every number, and the line between 3 and 2 is smaller than both so it would equal less, 1.

A food truck caters an event attended by 100 guests. Every guest orders one of two possible dishes: a salad or a turkey plate. The price of each meal decreases as more of that particular type are ordered. The price of a salad is $10.00 minus $0.06 for each salad ordered. The price of a turkey plate is $12.00 minus $0.02
multiplied by the square of the number of turkey plates ordered. Guests pay for their meal only after everyone has placed their order.
Using differentiation, find the maximum revenue for the food truck.
Remember that the number of meals is a positive integer. Round revenue to the nearest cent.
The Maximum Revenue, R for the food truck will be $528.056.
What is termed as maximum value?Maximum revenue is the highest value of a function within a given set of ranges. The maximum value of the function under the entire range is known as the absolute maxima, and the minimum value is recognized as the absolute minima.
Total Guests = 100
Each guest orders 1 of 2 dishes
Salad price = $10 - 0.06x
Turkey price = $12 - 0.02y²
So x + y = 100S = 10 - 0.06x
T = 12 - 0.02y²
Revenue = sx + ty
Revenue = (10 - 0.06x)x + (12 - 0.02y²)y
y = 100 - x
Therefore, Revenue = (10 - 0.06x)² + (12 - 0.02*(100 - x)²)*(100 - x)
R = 10x - 0.06[tex]x^{2}[/tex] + (12 - 0.02*(10000 - 200x + x²))*(100 - x)
R = 10x - 0.06[tex]x^{2}[/tex] + (12 - 200 + 4x -0.02x² )*(100 - x)
R = 10x - 0.06[tex]x^{2}[/tex] + (-188 + 4x -0.02 x² )*(100 - x)
R = 10x - 0.06[tex]x^{2}[/tex] + (-188 + 4x -0.02x² )*100 -x (-188 + 4x -0.02x²)R = 10x - 0.06[tex]x^{2}[/tex] + -18800 + 400x -2x² -x (-188 + 4x -0.02x²)
R = 10x - 0.06[tex]x^{2}[/tex] + -18800 + 400x -2x² + 188x - 4x² +0.02x³ R = 10x - 0.06[tex]x^{2}[/tex] + -18800 + 588x -6x² + 0.02x³
R = -18800 + 598[tex]x[/tex] - 6.06[tex]x^{2}[/tex] + 0.02[tex]x^{3}[/tex]
Using differentiation,dR/dx = 598 - 12.12x + 0.06x²
Equating to zero,598 - 12.12x + 0.06x² = 0Dividing both sides by 2, we have:299 - 6.06x + 0.03x² = 0x = -(-6.06)/(2*0.03) + root((-6.06)² - 4*0.03*299) / 2*0.03x = 101 - root(36.7236 - 35.88) / 0.06x = 101 - 14x = 86.94 ≅ 87
Therefore, when you sell 87 salad plates and 13 turkey dishes, that is where you will make Revenue.
Revenue = (10 - 0.06*87)*87 + (12 - 0.02(13)²)*13
Revenue = 416 + 112
R ≅ $528

y=2/5x-3
Step-by-step explanation:
So, first, let's find the slope. m=y1-y2/x1-x2. We will use our points and plug them into this equation. -9-(-7)/-5-(-10)=2/5. Our slope is 2/5. Now, let's find the y-intercept. We only need 1 point, I will choose (-10,-7). y=mx+b will help us find the y-intercept. -7=2/5(-10)+b. B is the y-intercept. -7=-4+b. -7-(-4)=-3. Our y-intercept is -3. So, using our y-intercept and slope, the equation is: y=2/5x-3

What is the quadratic equation?
A quadratic equation is an equation such that there is a quadratic polynomial.
Given that the x-intercept is (-3,0). The graph passes through the point (2, 10).
Assume that the equation is y = ax² + bx + 1.
Putting x = -3 and y = 0 in y = ax² + bx + 1:
0 = a×(-3)² + b×(-3) + 1
9a - 3b + 1 = 0 ....(i)
Putting x = 2 and y = 10 in y = ax² + bx + 1:
10 = a×(2)² + b×(2) + 1
4a + 2b - 9 = 0 ....(ii)
Multiply 2 with (i) and 3 with (ii), then add them:
18a - 6b + 2 + 12a + 6b - 27 = 0
30a - 25 = 0
a = 5/6

In the given question,
It is Nadine’s birthday, and she is making walnut brownies for her sleepover.
She invited eight of her friends to her party.
The recipe that she is using makes twenty-four brownies, but she only wants to make eight.
The recipe for twenty-four calls for [tex]4\frac{1}{2}[/tex] cups of walnuts.
We have to find how many cups of walnuts she needs for eight people.
From the question we know that the recipe that she is using makes twenty-four brownies.
For making twenty-four brownies she needs [tex]4\frac{1}{2}[/tex] cups of walnuts.
We can write [tex]4\frac{1}{2}[/tex] in simplified form by multiplying the 4 by 2 then add the result of multiplying 4 by 2 to 1.
So [tex]4\frac{1}{2}[/tex] = 9/2
24 brownies = 9/2 cups of walnuts
So 1 brownies = (9/2)/24 cups of walnuts
We can write it as
1 brownies = 9/2×1/24 cups of walnuts
Simplifying
1 brownies = 9/48 cups of walnuts
Since she have to make eight brownies.
So 8 brownies = 9/48×8 cups of walnuts
Simplifying
8 brownies = 9/6 cups of walnuts
8 brownies = 3/2 cups of walnuts
8 brownies =1 1/2 cups of walnuts
Hence, 1 1/2 cups of walnuts she will need for eight people.

[tex](f+g)(x)=3x^2-x-6[/tex]a³+ 1 + 2a² + 2a, a3 - 1 and a²+a2 +1
