There are a total of 30 students in the class. The equation used to solve the question is, 
× x = 24.
Step-by-step explanation:
Step 1; It is given that 24 students make up eight-tenths of the entire class. Assume the total number of students in class is x. So we have 24 will equal eight-tenths of x, as x is the total number of students.
The equation is × x = 24. Multiply both sides by 
× x × = 24 × , The and cancel out each other on the LHS.
x = 
= 30.
So there are 30 students in the class in total i.e. x = 30.
Step 2; To draw the bar chart, measure the entire length of the bar and divide it by 10. Shade eight-tenths of the bar and name it students that are going to the trip = 24, the remaining two-tenths is named students not going = 6.

Answer:
Step-by-step explanation:
The given triangle is a right angle triangle. The opposite side is given as 244 yards. The adjacent side is given as 119 yards. To determine the hypotenuse, we would apply Pythagoras theorem. It is expressed as
Hypotenuse^2 = opposite side^2 + adjacent side^2
Hypotenuse^2 = 244^2 + 119^2
Hypotenuse^2 = 59536 + 14161
Hypotenuse = √73697 = 271.5 yards.
cos θ = adjacent side/hypotenuse
cos θ = 119/271.5 = 0.4383
θ = Cos^-1(0.4383) = 64 degrees
The other angle would be
90 - 64 = 26 degrees
Answer:
Step-by-step explanation:
3( x - 8 ) = 9
x - 8 = 3
x = 3 + 8
x = 11
Answer:
5x+4y<=20
Step-by-step explanation:
We are expected to model the expression for the cost of the softball and the Hardball combined.
le the number of hardballs be x
let the number of softs balls be y
the cost of the hardballs is =5x
the cost of softball is =4y
therefore given that the total cost is =$20
the expression for the cost of x and y balls is given as
5x+4y<=20
