By what percent will a fraction increase if its numerator is decreased by 30%
а
and its denominator is decreased by 50%?
Answer:
40%
Step-by-step explanation:
Let x = numerator
Let y = denominator
[tex]\implies \dfrac{x}{y}[/tex]
Decreased by 30% = 100% - 30% = 70% = 70/100 = 0.7
Decreased by 50% = 100% - 50% = 50% = 50/100 = 0.5
[tex]\implies \dfrac{0.7x}{0.5y}[/tex]
[tex]\implies \dfrac{0.7}{0.5}=1.4[/tex]
[tex]\implies 1.4 \ \dfrac{x}{y}[/tex]
1.4 as a percentage = 1.4 x 100 = 140%
Therefore, the percentage increase is 140 - 100 = 40%

what is the constant of porportionality of the relationship shown in the graph.
Answer: The answer is 3
Step-by-step explanation:
The constant of proportionality of the relationship shown in the graph is 3 and this can be determined by using the two-point slope form of the line.
Given :
The graph of a straight line is given.
The following steps can be used in order to determine the constant of proportionality of the relationship shown in the graph:
Step 1 - The two-point slope form of the line can be used in order to determine the constant of proportionality of the relationship shown in the graph.
Step 2 - The two-point slope form of the line is given below:
y - y1 / x - x1 = y2 - y1 / x2 - x1
where (x1, y1) and (x2, y2) points on the line.
Step 3 - So, substitute (1,3) and (2,6) in the above equation.
y - 3 / x - 1 = 6 - 3 / 2 - 1
Step 4 - Simplify the above equation.
(y - 3) = 3(x - 1)
y - 3 = 3x - 3
y = 3x
So, the constant of proportionality of the relationship shown in the graph is 3. Therefore, the correct option is B).

the angles of a triangle are(x+10), (x+40) and (2x-30). Find the measure of all angles and name the type of triangle
Answer:
x=40
Step-by-step explanation:
(x+10)+(x+40)+(2x-30)=180
(x+x+2x)+(10+40-30)=180
4x+20=180 step 1: -20 on both sides
4x=160 step 2: /4 on both sides
x=40
Solve for X (Trigonometry)
Answer:
7.0
Step-by-step explanation:
When doing trigonometry, remember SOH-CAH-TOA...
Sine : Opposite/Hypotenuse
Cosine : Adjacent/Hypotenuse
Tangent : Opposite/Adjacent
In this figure, we are given the measure of a 23° angle, and two sides that are opposite of the angle, and the hypotenuse.
This means we need to use sine:
[tex]sin(23)=\frac{x}{18}[/tex]
Multiply both sides by 18:
[tex]18sin(23)=x[/tex]
[tex]18(0.391)=x\\x=7.038\\x\approx7.0[/tex]
find the area 8ft. 7ft. 14ft. ( EXPLAIN)
Answer:
The area is 77 ft.
Step-by-step explanation:
The formula for area of a trapezoid is 1/2 (base1 + base2) x height.
So, 1/2 (14+8) x 7 = 77.
Answer:
77Ft
if we were to ignore the extra "space" or area, and just do the area of the square we would get 8x7, but you probably want to know how I figured the area of both triangles, well this is simple the triangle has a height of 7 while it has a base(bottom) of 3 since 14-8(top)=6 and there are two triangles and they are the same lenght, when there is a triangle we do the base x height then divide by 2 since it's half a square so we do in this situation 3x7=21 and since there is another triangle we do it one more 3x7=21 add them together 3x7x2=42 then divide this by 2 and we get 21, we then add this to 56 which is the area of the square and get our result 77ft
Conjecture: The product of the lengths of the two legs of a right triangle is equal to the product of the lengths of the hypotenuse and the altitude.
Is this true? Use Geogebra to help you create a figure to use in support of your conclusion. Insert a screenshot and show all of your calculations.

Which absolute value inequality is modeled by this graph?
A.
y < |x − 2 | − 2
B.
y > |4x + 2| − 2
C.
y > |2x − 4| − 2
D.
y < |3x − 6| − 2
Answer: Choice D
y < |3x − 6| − 2
============================================================
Explanation:
Writing y < |3x − 6| − 2 is the same as y < 3|x − 2| − 2 when factoring out the GCF from the absolute value brackets.
Let's look at a breakdown of each piece of y < 3|x − 2| − 2
The 3 out front means "vertically stretch by a factor of 3".The x-2 means we shift 2 units to the right.The -2 at the very end means "shift 2 units down"If we started with the parent V shaped graph of y = |x|, and applied those transformations listed above in the bullet points, then we'd get the boundary shown in the graph. The boundary is a dashed line to indicate "points on the boundary are NOT part of the shaded solution set". If we had an "or equal to" then we would include boundary points with a solid boundary line.
We shade below the dashed boundary to complete the shaded region for y < |3x − 6| − 2 aka y < 3|x − 2| − 2

Start by factoring out a 5:
[tex]5(x^2-7x+12)[/tex]
We need to find two integers that have a product of 12, and a sum of -7:
(-3)(-4)=12
-3-4=-7
We can split -7x into -3x and -4x
[tex]5(x^2-3x-4x+12)[/tex]
Factor each half separately:
[tex]5[x(x-3)-4(x-3)][/tex]
Since x and -4 are both being multiplied by x-3, we can combine them:
[tex]5(x-3)(x-4)[/tex]
A dozen cupcakes cost $36. What is the rate, and the unit rate?
Answer:
A unit rate has a denominator of 1 unit when the rate is written as a fraction. To write a rate as a unit rate: divide the numerator and the denominator of the rate by the denominator. Example #1: A rate compares two quantities of different units. Each part of the rate must be labeled!

Fill in the blank so that the ordered pair is a solution of y=9x - 9.
( ), 63
Answer:
(8, 63)
Step-by-step explanation:
The ordered pair is a solution to the equation when substituting the values for x and y make the equation a true statement.
If we let x represent the first number of the ordered pair, it will be a solution when ...
63 = 9x -9
7 = x -1 . . . . . . . divide by 9
8 = x . . . . . . . add 1
The blank gets filled with 8, so the ordered pair is (8, 63).

Solve the following system of equations
Y= -2x – 3
4y + x =16
Answer:
(-4,5)
*View attached graph*
Step-by-step explanation:
y = -2x - 3
4y + x = 16
4y + x = 16
4(-2x - 3) + x = 16
-8x - 12 + x = 16
-7x - 12 = 16
+12 + 12
-7x = 28
/-7 /-7
x = -4
4y + x = 16
4y + (-4) = 16
4y - 4 = 16
+ 4 + 4
4y = 20
/4 /4
y = 5
(x,y) -> (-4,5)
Hope this helps!
