Given:
Number of gym members in last quarter = 490
Number of gym members in this quarter = 686
To find:
The percent of increase in the number of members.
Solution:
We have,
Number of gym members in last quarter = 490
Number of gym members in this quarter = 686
Now, the percent of increase in the number of members.
[tex]\%\text{ of increase}=\dfrac{{Members in this month - Members in last month}}{\text{Members in last month}}\times 100[/tex]
[tex]\%\text{ of increase}=\dfrac{686-490}{490}\times 100[/tex]
[tex]\%\text{ of increase}=\dfrac{196}{490}\times 100[/tex]
[tex]\%\text{ of increase}=\dfrac{2}{5}\times 100[/tex]
[tex]\%\text{ of increase}=2\times 20[/tex]
[tex]\%\text{ of increase}=40[/tex]
Therefore, the gym members increased by 40%.

Class A has 26 pupils and class B has 15 pupils.
Both classes sit the same maths test.
The mean score for class A is 33.
The mean score for both classes is 39.
What is the mean score (rounded to 1 DP) in the maths test for class B?
Answer:
Concept: Real World Analysis
So we know A has an average of 33We know A+B/2= 39Hence we will solve for b [tex] \frac{33 + x}{2} = 39[/tex][tex]x = 45[/tex]Answer:
It's 49.4
Step-by-step explanation:
((26*33)+(15*x))/41＝39
((858)+(15*x))/41＝39 ‖*41
(858)+(15*x)＝1599 ‖-858
15*x＝741 ‖/15
x＝49.4

The Blues Festival sold 20% of tickets at a reduced price of $30 and 30% of tickets at $40 and the rest at the door for full price of $50. With 10,000 tickets sold, how much did they earn from ticket sales in dollars?
Answer:
$430,000
Step-by-step explanation:
20% of 10,000 = 2000
therefore, 2000 x $30 = $60,000
30% of 10,000 = 3000
therefore, 3000 x $40 = $120,000
50% of 10,000 = 5000
therefore, 5000 x $50 = $250,000
add all dollar amounts together to get $430,000
I need to simplify the complex fraction.
Answer:
(15 – 22x)/4x(2x – 5)
Step-by-step explanation:
Let us take the numerator first:
(1/2x – 5) – (7/8x – 20) = (1/(2x – 5)) – (7/4(2x –5)) = (8x – 20 – 7(2x – 5))/(4(2x – 5)(2x – 5)
= (8x – 20 – 14x + 35)/4(2x – 5)² = (15 – 22x)/4(2x – 5)²
The denominator is: x/2x – 5
So we now have:
(15 – 22x)/4(2x – 5)² ÷ x/(2x – 5) = (15 – 22x)/4(2x – 5)² x (2x – 5) /X = (15 – 22x)/4x(2x – 5)
In the inequality

f (x) = 2x² - 10x + 13
Find f (-4)
Answer:
85
Step-by-step explanation:
In this question, you would solve by plugging in -4 to x.
Solve:
f(-4) = 2(-4)² - 10(-4) + 13
= 2(16) + 40 + 13
= 32 + 40 + 13
= 72 + 13
= 85
f(-4) = 85

How we can differentiate between direct proportion and inverse proportion?
Answer:
Please check explanations for answer
Step-by-step explanation:
Here, we want to differentiate between inverse and direct proportion
Let x and y be two quantities
If they are directly proportional;
x/y = k
x = ky
where k is proportionality constant
If inversely;
xy = k
In verbal terms;
For direct proportionality, when one value increase, the other too does so and vice versa
For inverse, when one value inverse, the other decrease

in the following figures find the value of angle COD if angle abc is equal to 75 degree and a b is equal to CD
Angle AOB is given as 75 degrees.
O is the center of the circle so AO and CO are the same length. AB and CD are the same length, so angle COD would be the same as AOB
COD = 75 degrees.
Answer:
75°
Step-by-step explanation:
It is given that:
AB and CD are chords of the circle which are equal. Equal chords subtends equal angles at the center of the circle. [tex] \because m\angle AOB = 75\degree [/tex] [tex] \therefore m\angle COD = 75\degree [/tex]cynthia and amy are customer service representives cynthia earns $13 per hour and amy earns $1.50 more per hour than cynthia. Amy worked 43.5 hours in the last two weeks which equation could she use to find the amount of money she should receive
Answer:
Step-by-step explanation:
Let h bet the # of hours worked
If Cynthia earns $13 per hour then her equation would be:
C = $13h
If Amy makes $1.5 more per hour then her equation would be:
A = $14.5x
Now lets plug in some numbers:)
A = $14.5(43.5)
A = $630.75

A Large earthworm can travel 25 centimeter in 12 seconds. How many meters does the earthworm travels in1 minute?
We know that it can travel 25 centimetres in 12 seconds. First, we break down the minute into seconds.
60/12= 5
______________________________
Now, multiply 25 by 5.
25x5=125
__________________________________
With this knowledge, we just have to convert the centimetres, to meters.
_______________________________
Your answer is 1.25 meters :)

Hello! Could you please help with these? It was due quite a long time ago. I have a D in this class and need to get my grades up.
Answer:
16. [tex]y=7x[/tex]
17. [tex]y=0.5x[/tex]
18. [tex]y=3x[/tex]
19. [tex]y=2x[/tex]
Step-by-step explanation:
Equation is [tex]y=kx[/tex] where k is a constant of proportionality.
16.
[tex]\frac{y}{x}=\frac{10.5}{1.5}=\frac{14}{2}=\frac{24.5}{3.5}=\frac{35}{5}=7[/tex]
So, equation is [tex]y=7x[/tex]
17.
[tex]\frac{y}{x}=\frac{1}{2}=\frac{2}{4}=\frac{2.5}{5}=\frac{3.5}{7}=\frac{1}{2}=0.5[/tex]
Equation is [tex]y=0.5x[/tex]
18.
[tex]\frac{y}{x}=\frac{6}{2}=\frac{9}{3}=\frac{15}{5}=\frac{18}{6}=3[/tex]
Equation is [tex]y=3x[/tex]
19.
[tex]\frac{y}{x}=\frac{4}{2}=\frac{8}{4}=\frac{14}{7}=\frac{18}{9}=2[/tex]
Equation is [tex]y=2x[/tex]
