11/3....this is rational because it is a fraction
sqrt 48.....irrrational because it cant be made into a fraction
6.25....rational
0.01045....if this terminates(ends), it is rational
sqrt 16/81....rational because it equals 4/9
sqrt 3/16....irrational
0.42...rational
16pi....irrational
Answer:
ok?
Step-by-step explanation:
Sure friend what do you need help with? I will help you
Step 1: begin by writing the formula for slope intercept form
step2: substitute the given slope for X
step3: use the order pair you given (x,y) and substitute these values for the variables x and y in the equation
step4: solve for y ( y-intercept of the graph)
step5: rewrite the original equation in step 1 substituting the slope for x and the y-intercept for y
3x+3=192 is the equation
To solve the equation, you would subtract 3 from both sides, 3-3 cancels out, so 192-3= 189. Then, you are left with 3x=189 so you divide both sides by 3, 3x divided by 3 cancels out, so you do 189 divided by 3 which is 63.
Answer to equation: x=63
Equation: 3x+3=192
For this case, the first thing to do is find the area of the trapezoid.
We have then:
Where,
b1: b2: Trapezoid bases
h: height of the trapezoid
Substituting values we have:
Then, the cost per square foot is given by:
Answer:
The new carpet for the room will cost:
C = 1072.5 $
