Step-by-step explanation:

14) percentage of increase

% of increase = (new - original)/original × 100

= (40 - 35)/35 × 100

= 5/35 × 100

= 14.285% = 14% increase

15) percentage of decrease

% of decrease = (original - new)/original × 100

= (16 - 10)/16 × 100

= 6/16 × 100

= 37.5% = 38% decrease

16) percentage of increase

% of increase = (new - original)/original × 100

= (73 - 27)/27 × 100

= 46/27 × 100

= 170.37% = 170% increase

17) percentage of decrease

% of decrease = (original - new)/original × 100

= (92 - 21)/21 × 100

= 71/21 × 100

= 338.10% = 338% decrease

18) percentage of decrease

% of decrease = (original - new)/original × 100

= (21.2 - 10.8)/21.2 × 100

= 10.4/21.2 × 100

= 49.06% = 49% decrease

19) percentage of increase

% of increase = (new - original)/original × 100

= (25 - 11)/11 × 100

= 14/11 × 100

= 127.27% = 127% increase

20) percentage of increase

% of increase = (new - original)/original × 100

(76 - 68)/68 × 100

8/68 × 100 = 11.77% = 12%

21) percentage of increase

% of increase = (new - original)/original × 100

= (40 - 21)/21 × 100

= 19/21 × 100

= 90.47% =90%

22) New car = AED 45,500

Used car = x

New car = (25% of x) + x

45,500 = (25x/100) + x

45,500 = (25x + 100x)/100

45,500 = 125x/100

45,500 × 100 = 125x

4,550,000 = 125x

x = 4,550,000/125 = 36,000

x = AED 36,000

The function f(x) = 1.50x – 30 gives the amount of money Amelia has to spend each week for x school lunches, after taking money
Naya [18.7K]
To find the inverse, switch the x and y, and then solve for y (f(x) is the same as y)

So we get:
x=1.50y-30 (add 30 to both sides)
x+30=1.50y (divide both sides by 1.5)
x/1.5+30/1.5=y
y=x/1.5+20

Hope this helps

Please help me solve this
andre [41]

Answer:

Step-by-step explanation:

This number is much larger than 1. You need to start at the decimal and move left (that's how scientific notation works for numbers larger than 1.)

So the answer is 1.0054 * 10 ^7

The person doing this started at the 1 and moved right until he/she hit the decimal. Wrong direction.

A cone has a radius of 5 ft and a height of 15 ft. It is empty and is being filled with water at a constant rate of 15 15 ft 3 f
kvasek [131]

Answer:

\frac{dr}{dt}=0.11062ft/sec

Step-by-step explanation:

From the question we are told that:

Radius r=5ft

Height H=15ft

Rate R=15ft/3sec =5ft/s

Surface Radius R_{surf}=2.2ft

Generally the equation for Volume is mathematically given by

 V=\frac{1}{3}\pi*r^2h

Since radius to height ratio gives

 \frac{r}{h}=\frac{5}{15}

 \frac{r}{h}=\frac{1}{3}

 h=3r

Therefore

 V=\frac{1}{3}\pi*r^2(3r)

 V=\pi r^3

Generally the equation for Change of Volume is mathematically given by

 \frac{dv}{dt}=\pi \frac{d}{dt}(r^3)

 \frac{dv}{dt}=\pi 3*r^2 \frac{dr}{dt}

 \frac{dv}{dt}=\pi 3*(2.2)^2 \frac{dr}{dt}

 \frac{dr}{dt}=\frac{5}{45.62}

 \frac{dr}{dt}=0.11062ft/sec
