Answer: 7/8
Step-by-step explanation: Notice that 1/2 and 3/8 are unlike fractions. Our first when adding unlike fractions is to get a common denominator.
The common denominator of 2 and 8 will be the least common multiple of 2 and 8 which is 8.
To get an 8 in the denominator of 1/2, we multiply the numerator and the denominator by 4 which gives us 4/8.
Notice that 3/8 already has an 8 in the denominator so we leave it how it is.
Now we are adding like fractions.
To add like fractions, or fractions that have the same denominator, simply add the numerators and keep the original denominator.
So here, if we add the numerators we have 4 + 3 which gives us 7 and we put this over our original denominator which is 8 and we have our answer. Also, notice that 7/8 is in lowest terms so it's our final answer.
This means that 3/8 + 1/2 = 7/8
Y= -x + 2 and y= 3x - 4
As these both equal y, you know that they both equal each other so
-x + 2 = 3x - 4
Third option :)
I think this is suppose to be
x y
2 1400
4 1000
you see at 2 hours they have 1400 left and at 4 hours they have 1000 feet left.
first we need y intercept or b since we will put it in y=mx+b form
so at x= 0 whats y. Based on this every 2 hours you climb 400. so go back from x=2 to x=0 would make 1000 into 1800 feet left
so at x hours you have 1800 left
y - intercept is (0, 1800) or +1800
now we need slope
difference in y / difference in x
diff in y = 1400-1000 = 400
diff in x = 2 - 4 = -2
difference in y / difference in x = 400/-2 = -200 is the slope
y=mx+ b for
y=-200x+1800

A=2πrh+2πr2=2·π·3·6+2·π·32≈169.646
Answer:
Step-by-step explanation:
LA (Lateral area) = P (perimeter of the base) x h (distance between bases)
LA = 3 x 2
LA = 6
SA (surface area) = LA (Lateral area) + (2 x B (Area of the base))
SA = 6 + (2 x 0.25)
SA = 6.5m²
