Answer:

60

Step-by-step explanation:

last year 1/5 of the class played sports, so s = (1/5) c

the next year, s increased by 5, c increased by 10 and the fraction changed to 1/4, so for the next year (s+5) = (1/4)(c+10)

To solve this we can substitute s = (1/5)c from the first equation into the second, so

((1/5)c + 5)=(1/4)(c+10), simplify both sides

(1/5)c + 5 = (1/4)c + 10/4, simplify 10/4 to 5/2

(1/5)c + 5 = (1/4)c + 5/2, multiply both sides by 20 to eliminate fractions (least common multiple of 2, 4 and 5)

4c + 100 = 5c + 50, subtract 4c, subtract 50 from both sides

50 = c, number of students in class last year was 50, this year is 10 more, so this year is 60

butalik [34]

Answer:

300K

Step-by-step explanation:

T = t + 273 °C

T is absolute temperature

t = given temperature (27°C in this case)

Hence T = 27 °C + 273 °C (standard temperature)

T = 300K (since absolute temperature is measured in K from the question's preamble)

If the parent function f(x) = (2x − 3)3 is transformed to g(x) = (-2x + 3)3, which type of transformation occurs? A. vertical sh
exis [7]

Answer:

The answer is C

Step-by-step explanation:

We have f(x) function as below:

f(x)=(2x-3)^3

and the converted function g(x) is as mentioned below:

g(x)=(-2x+3)^3

We can observe that:

f(x)=-g(x)

Therefore it can be said that this function reflected horizontally.

Note: please check the plot attached.
