Did I do it right ?
Answer:
For number three you did everything correct.
But, number 4 it has to be equal to.
[tex]3/6=1/2[/tex]
They are equal to each other.
So just change it to an equal sign and your good.

Paula is 3 years older than
Lindsey, who is 2 years
younger than Dave. If Paula is
17, how old is Dave?
Answer:
16
Step-by-step explanation:
If Paula is 17, then Lindsey is 17-3 (14). Since Lindsey is 14, Dave is 2+14 (16), so Dave is 16
Answer:
16 years old
Step-by-step explanation:
Let Lindsey's age be x.
Paula's age be x+3
Dave age be x+2
If Paula is 17.
x+3=17
x=14
x+2
(14)+2=16
Dave is 12 years old.

Answer:
431,707
Step-by-step explanation:
To figure out the total number, you need to divide the part of the whole by the percentage it is of the whole. This means that you need to divide 35,400 by 8.2%.
Before dividing the percentage, you need to convert it to a decimal.
8.2% = 0.082
Divide the number to find the answer.
35,400/0.082 = 431,707.3
Converted to the nearest whole number, the answer is 431,707.
Find dy/dx by implicit differentiation for x – y = xy.
Answer:
[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1-y}{1+x}[/tex]
Step-by-step explanation:
Differentiate xy using the product rule, then
Given
x - y = xy
1 - [tex]\frac{dy}{dx}[/tex] = x. [tex]\frac{dy}{dx}[/tex] + y. 1 = x[tex]\frac{dy}{dx}[/tex] + y ( subtract 1 from both sides )
- [tex]\frac{dy}{dx}[/tex] = x [tex]\frac{dy}{dx}[/tex] + y - 1 ( subtract x [tex]\frac{dy}{dx}[/tex] from both sides )
- [tex]\frac{dy}{dx}[/tex] - x [tex]\frac{dy}{dx}[/tex] = y - 1 ( multiply through by - 1 )
[tex]\frac{dy}{dx}[/tex] + x[tex]\frac{dy}{dx}[/tex] = 1 - y
[tex]\frac{dy}{dx}[/tex] (1 + x) = 1 - y ← divide both sides by (1 + x)
[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1-y}{1+x}[/tex]
The differentiation of the function x - y = xy is dy/dx = (1-y)/(x+1).
What is differentiation?Differentiation is a method of finding the derivative of a function.
It shows instantaneous rate of change in a function.
The given expression is,
x - y = xy
Differentiate with respect to x,
d/dx (x-y) = d/dx (xy)
Use multiplication formula for differentiation,
d/dx(ab)= a.db/dx+da/dx.b,
1 - dy/dx = x.dy/dx + y. 1
1 - dy/dx = x.dy/dx + y
1 - y =x.dy/dx + dy/dx
1 - y = (x+1).dy/dx
dy/dx = (1-y)/(x+1)
The differentiation of the function x - y = xy is dy/dx = (1-y)/(x+1).

The square based pyramid is cut horizontally at a height of 15cm to leave this frustum. Calulate the volume of the frustum.
Answer:
The answer is given below
Step-by-step explanation:
The question is not complete. The correct question is:
A square based pyramid have a height of 30 cm and base of 10 cm. The The square based pyramid is cut horizontally at a height of 15cm to leave this frustum.
Answer:
The frustum would have a base of 10 cm and height of 15 cm. The lower base has a length of 10 cm. to calculate the upper base, we use the formula:
[tex]\frac{height\ of\ frustum}{height\ of \ pyramid}=\frac{base \of\ upper\ edge}{base \of\ lower\ edge}[/tex]
Substituting:
[tex]\frac{30}{15}=\frac{10}{b} \\ b=15*10/30=5[/tex]
The volume of the frustum is given by the formula:
[tex]V=\frac{h}{3}(A_1+A_2+\sqrt{A_1A_2} )[/tex]
Where h is the height of the frustum = 15 cm, A1 is the area of the lower base = 10 * 10 = 100 cm², A1 is the area of the upper base = 5 * 5 = 25 cm²
Substituting gives:
[tex]V=\frac{h}{3}(A_1+A_2+\sqrt{A_1A_2} )=\frac{15}{3}(100+25+\sqrt{100*25} )= 875\ cm^3[/tex]

Use △XYZ, in which ∠X is a right angle and tanY=815.
Answer:
8/17
Step-by-step explanation:
The correct and complete question is:
Use △XYZ, in which ∠X is a right angle and tanY=8/15. What is the ratio for sinY?
From definition:
tan(Y) = opposite/adjacent
From the graph and the question:
tan(Y) = XZ/XY = 8/15
Then:
XZ = 8 and XY = 15. Using pytaghorean theorem:
XZ² + XY² = YZ²
8² + 15² = YZ²
√289 = YZ
17 = YZ
From definition:
sin(Y) = opposite/hypotenuse
From the graph:
sin(Y) = XZ/YZ
sin(Y)= 8/17

PLEASE HELP!! Solve system of equations
I think you use desmos but mine isn’t working
Answer:
The solution of system of equations is (1 , 5)
Step-by-step explanation:
The first equation is:
3y + 2x = 17
The second equation is:
-x - 4y = -12
3y + 2x = 17 :
For x = 0 , y = 5.67
For x = 1 , y = 5
For x = 2 . y = 4.33
For x = 3 , y = 3.67
For x = 4, y = 3
-x - 4y = -21 :
For x = 0 , y = 5.25
For x = 1 , y = 5
For x = 2 . y = 4.75
For x = 3 , y = 4.5
For x = 4, y = 4.25
Solve the system of Equations:
3y + 2x = 17 ⇒ a
-x - 4y = -21 ⇒ b
Multiply equation b by -1:
x + 4y = 21
Rearrange:
x = 21 - 4y
Substitute x into equation a:
3y + 2(21-4y) = 17
3y + 42 - 8y = 17
-5y = 17 - 42
-5y = -25
y = 5
Substitute y in equation b:
-x - 4(5) = -21
-x -20 = -21
-x = -21+20
-x = -1
x = 1
What is the equation of a line with a slope of -3 and a y-intercept of 4
Answer:
y = -3x + 4
Step-by-step explanation:
So the -3 is the slope and the slope always has an x and the y intercept is b which is 4
Answer:
y = -3x + 4
Step-by-step explanation:
slope-intercept form: y = mx + b
Note that: m = slope
y- intercept = b
m = slope = -3
y-intercept = b = 4
Plug in the corresponding number to the corresponding variables:
y = mx + b
y = -3x + 4 is your answer.

What is a Bar graph?Using rectangular bars with heights or lengths proportionate to the values they represent, a bar chart or bar graph displays categorical data. Both a vertical and a horizontal bar plot are possible. Sometimes referred to as a column chart, a vertical bar graph.
Discrete, continuous, or categorical data are typically organized into class intervals in bar charts. They are made up of a set of marked horizontal or vertical bars and an axis.
Given data ,
Let the bar graph be represented as A
Now , the x axis of the bar graph is represented by the class
where Class = { 0.320 - 0.329 , 0.330 - 0.339 , 0.340 - 0.349 , 0.350 - 0.359 , 0.360 - 0.369 }
And , the y axis of the graph represents the frequency of the class
where Frequency = { 1 , 14 , 12 , 2 , 1 }
