Answer:
30/45 or 2/3
Step-by-step explanation:
If you factor out a 10 from the numerator and a 9 from the denominator, you should get the following:
Numerator = 10 (a + b)
Denominator = 9 (x - y)
Since we know that (a + b) = 3 and (x - y) = 5, we can rewrite it as:
Numerator = 10(3)
Denominator = 9(5)
Therefore, the answer is 30/45, or 2/3.
Hope this helps!
Answer: 2/3
Look at what you are getting on the right hand question. 10a+10b has a common factor that can be taken out: 10
10a + 10b = 10(a+b)
Now look at the denominator:
9x-9y = 9(x-y)
There are many answers
Personally, I would multiply 3/5 * 10/9 = 30/45 = 2/3 thus the answer is 2/3

Lan make 60 cakes. he gives 1/4 of the cakes to Helen. he gives 20 of the 60 cakes to sue. what fraction of the 60 cakes does he have left?
Answers
Answer:
5/12
Step-by-step explanation:
1/4 × 60 = 15
He gave 15 cakes to Helen.
He gave 20 cakes to Sue.
20 + 15 = 35
He gave away a total of 35 cakes.
60 - 35 = 25
He has 25 cakes left.
fraction = 25/60 = 5/12

Step-by-step explanation:
Coordinate point "G" on this graph is on the very bottom. On the X axis, point G is on the 6. On the Y axis, its on the 0, so since the domain, (X) comes first before the range, (Y), you get (6, 0)

f(x)=x^2. what is g(x)?
A. g(x)= 3x^2
B. g(x)= (1/3x)^2
C. g(x)= 1/3x^2
D. g(x)= 1/9x^2
Answers
Answer:
See Down Here
Step-by-step explanation:
We want to get g(x) given that we know f(x) and the graphs for both functions. We will see that the correct option is D:
g(x) = (x/3)^2
By looking at the graph we can see that f(x) and g(x) are two quadratic functions, and g(x) is just a dilation of f(x).
This means that:
g(x) = A*f(x)
Where A is a real number.
We know that:
f(x) = x^2
And by looking at the graph, we also know that g(3) = 1.
Then we can write:
g(3) = A*f(3) = A*3^2 = 1
Now we can solve this for A:
A*3^2 = 1
A*9 = 1
A = 1/9
Then we have:
g(x) = (1/9)*f(x) = (1/9)*x^2 = (x/3)^2
So the correct option is D.

Angle one and two lie on straight line.
this means there sum is equal to 180°
Given :-
angle 1 = 7x angle 2 = x+12so we can say :-
[tex] \angle1 + \angle2 = 180 \degree \\ 7x + x + 12 = 180 \\ 8x + 12 = 180 \\ 8x = 180 - 12 \\ 8x = 168 \\ x = \frac{ \cancel{168} {}^{ \: \: 21} }{ \cancel8} \\ x = 21 \degree[/tex]
so angle one = 7x= 7×21 = 147°

Find the residual values, and use the graphing calculator tool to make a residual plot. A 4-column table with 5 rows. The first column is labeled x with entries 1, 2, 3, 4, 5. The second column is labeled given with entries negative 3.5, negative 2.9, negative 1.1, 2.2, 3.4. The third column is labeled predicted with entries negative 1.1, 2, 5.1, 8.2, 1.3. The fourth column is labeled residual value with all entries blank. Does the residual plot show that the line of best fit is appropriate for the data? Yes, the points have no pattern. No, the points are evenly distributed about the x-axis. No, the points are in a linear pattern. Yes, the points are in a curved pattern.
Answers
The best answer from the options that proves that the residual plot shows that the line of best fit is appropriate for the data is: ( Statement 1 ) Yes, because the points have no clear pattern
X Given Predicted Residual value
1 3.5 4.06 -0.56
2 2.3 2.09 0.21
3 1.1 0.12 0.98
4 2.2 -1.85 4.05
5 -4.1 -3.82 -0.28
The residual value is calculated as follows using this formula: ( Given - predicted )
1) ( 3.5 - 4.06 ) = -0.56
2) ( 2.3 - 2.09 ) = 0.21
3) ( 1.1 - 0.12 ) = 0.98
4) (2.2 - (-1.85) = 4.05
5) ( -4.1 - (-3.82) = -0.28
Residual values are the difference between the given values and the predicted values in a given data set and the residual plot is used to represent these values .

===========================================================
Explanation:
There are two approaches here.
Method 1
Focus on the numbers along the top only.
The left arrow points at 50 while the arrow on the right points at 180. Subtract these numbers to get 180 - 50 = 130
------------------------------
Method 2
Focus on the numbers along the bottom row this time.
The left arrow points at 130 and the right arrow points at 0
The difference of which is 130 - 0 = 130
Because we're subtracting off 0, it means we can simply look at only one number without having to do any math. This only works if the other portion of the angle is pointing at 0 or 180.
------------------------------
Notice that 130 degrees is larger than 90, so this angle is obtuse. This means that if you aren't sure whether to go with 50 or 130, it will depend on if it's acute or obtuse.

Don't worry about the x and w, I just need the answer to y. Find the value of y if JKLM~PQRS
Answers
Answer:
y = 15
Step-by-step explanation:
JKLM ~ PQRS means that quadrilateral JKLM is similar to quadrilateral PQRS.
In similar shapes the corresponding sides have same ratio and the corresponding angles are congruent.
This means angle J is congruent to angle P, K is congruent to Q, L is congruent to R and M is congruent to S. Order of the vertices matters.
Solving for y.
Angle J is congruent to angle P.
5y - 4 = 71 Add 4 on both sides.
5y = 71 + 4
5y = 75 Divide both sides with 5.
y = 15
