By what percent will a fraction increase if its numerator is decreased by 30%
а
and its denominator is decreased by 50%?
Answers
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%
The radius of a circle is 10 meters. What is the length of a 135° arc?

The total circumference of the circle is: C = 2*pi*radius = 2*(3.14159)*(6) = 37.7 m The total circle has 365o. Your arc has only 135o. Hence: 135o x------- = -------------365o 37.7 m where x is the length of the 135o arc. Solve for x.
find the area 8ft. 7ft. 14ft. ( EXPLAIN)
Answers
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

Answers
Answer:
x = 15
Step-by-step explanation:
[tex]12.45=4.95+0.5\timesx[/tex]×x
Solve the equation
[tex]12.45=4.95+0.5x[/tex]
Rearrange variables to the left side of the equation
[tex]-0.5x=4.95-12.45[/tex]
Calculate the sum or difference
[tex]-0.5x=-7.5[/tex]
Divide both sides of the equation by the coefficient of variable
[tex]x=\frac{-7.5}{-0.5}[/tex]
Determine the sign for multiplication or division
[tex]x=\frac{7.5}{0.5}[/tex]
Multiply both the numerator and denominator with the same integer
[tex]x=\frac{75}{5}[/tex]
Cross out the common factor
[tex]x=15[/tex]

Solve for X (Trigonometry)
Answers
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]

(x+x+2x)+(10+40-30)=180

4x=160 step 2: /4 on both sides

Fill in the blank so that the ordered pair is a solution of y=9x - 9.
( ), 63
Answers
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).
