Divide the number satisfied by total people surveyed then multiply by 100 for the percent.

960/2400 = 0.4

0.4 x 100 = 40%

The answer is 40%

Which one is it !? How do you do it ? It’s timedddd

wel

heres a key for then

SIN= O/H

COS= A/H

TAN= O/A

CSC= H/O

SEC= H/A

COT= A/O

let me know if u have anymore questions

Answer:

3/5 is ur answer

Step-by-step explanation:

ok so its SIN

SIN is o/h (o= opposite and h= hypotenuse)

so we can look at the picture and it says find the SIN of a

ok so the O would be 3 and the H would be 5

so ur answer would be 3/5

A cyclist traveled 9 kilometers per hour faster than an in-line skater. In the time it took the cyclist to travel 45 kilometers,

coldgirl [10]

Answer:

18 kmh

Step-by-step explanation:

Given: Speed of cyclist is 9 km/h more than skater´s speed.

Distance covered at the given time by cyclist is 45 km and by skater is 30 km.

Let´s assume the speed of skater be "x"

∴ Speed of cyclist will be $(x+9) km/h$

Remember; time= $\frac{Distance}{speed}$

We know the time taken by both cyclist and skater are same.

∴ we can form an equation to find the speed of skater.

Time taken by cyclist= time taken by skater

⇒ $\frac{45}{(x+9)} = \frac{30}{x}$

Multiplying both side by $(x+9)\ and\ x$

⇒ $45x= 30\times (x+9)$

Using distributive property of multiplication

⇒ $45x= 30x+270$

Subtracting both side by 30x

⇒ $15x= 270$

Dividing both side by 15

⇒ $x= \frac{270}{15}$

∴ $x= 18\ kmh$

Hence, speed of the skater is 18 kmh
