As part of a survey, 150 students were asked to name their favorite class. 50 points

1 answer:

5 0

A:40%
If you put 60 over 150 and x(percent of students) over 100 and cross multiply 100 and 60, you will get 6000. You then divide that by 150 which leaves you with 40 as x and 40 over 100 is 40%.

Step-by-step explanation:

thing to note:

sin = opposite/hypotenuse

cos = adjacent/hypotenuse

tan = opposite/adjacent

hypotenuse= side across 90 degree angle

adjacent= remaining side

angle B

sin = 6/10

cos = 8/10

tan = 6/8

angle C

sin = 8/10

cos = 6/10

tan = 8/6

hope that helped. let me know if you have any questions:)

What is the average speed of a car that travels 80 km in 1.5 hours

ludmilkaskok [199]

Answer:

53 1/3 km/h

Step-by-step explanation:

The car is going at 80km in 1.5 hours, so if you divide that value you get 26 2/3 km for every half hour, now you would want to multiply this times 2 to find the value for every hour, so then this would give you the answer 53 and 1/3 kilometers per hour.

What is the solution to this equation?<br> 9x - 4(x - 2) = x + 20

ioda

9x - 4(x - 2) =x + 20

We move all terms to the left:

9x -4(x - 2) - (x + 20) = 0

Multiply

9x - 4x -(x + 20) + 8 = 0

We get rid of the parentheses.

9x - 4x - x - 20 + 8 = 0

We add all the numbers and all the variables.

4x - 12 = 0

We move all terms containing x to the left hand side, all other terms to the right hand side

4x=12
x = 12/4
x = 3
