You have a wooden rod which is 24 1/2 inches long. Carlos needs a piece which is 8 3/4 inches long and Amanda needs a piece which is 6 3/8 inches long. How long will the rod be after you cut those pieces to give to Carlos and Amanda?
Answers
Answer:
8 3/4 inches
Step-by-step explanation:
Total length of the rod = 24 1/2 inches
Carlos = 8 3/4 inches
Amanda = 6 3/8 inches
length of the rod remaining = Total length - ( Carlos + Amanda)
= 24 1/2 - (8 3/4 + 6 3/8)
= 49/2 - (35/4 + 51/8)
= 49/2 - ( 75+51/8)
= 49/2 - 126/8
= 196-126/8
= 70/8
= 8 6/8 inches
= 8 3/4 inches
Length of rod remaining = 8 3/4 inches

9 3/8

1/2h+1/3(h-6)=5/6h+2
Answers
Hey there! I'm happy to help!
First we use the distributive property to undo the parentheses.
1/2h+1/3h-2=5/6h+2
We combien like terms.
5/6h-2=5/6h+2
We subtract 5/6 h from both sides.
-2=2
There are no solutions because this equation is not true so therefore no possible x value can satisfy it.

If an airplane travels 110 mph for 5 hours, what is the total distance traveled?
Answers
Answer:
550 miles
Step-by-step explanation:
[tex]Distance=Speed\times Time[/tex]
[tex]Distance = 110mph \times 5h = 550\ miles[/tex]
Total Distance travelled by the airplane is 550 miles
What is Distance?Distance is a numerical measurement of how far apart objects or points are.
What is Speed?The speed of an object is the magnitude of the rate of change of its position with time or the magnitude of the change of its position per unit of time
Given,
Speed of the airplane = 110 mph
Time = 5 hours
Distance = Speed × Time
=110 ×5
=550 miles
Hence, the total distance travelled by the airplane is 550 miles

A perfect square trinomial is a trinomial that factors as two identical binomials.
For example, x² + 8x + 16 factors as (x + 4)(x + 4) or (x + 4)².
Another example would be x² - 12x - 36 which factors as (x - 6)².

If f(x)=ln x and g(x)=e^x+1 find f(g(2))-g(f(e)) please help!!
Answers
Answer:
ln (e^2 + 1) - (e+ 1)Step-by-step explanation:
Given f(x) = ln and g(x) = e^x + 1 to get f(g(2))-g(f(e)), we need to first find the composite function f(g(x)) and g(f(x)).
For f(g(x));
f(g(x)) = f(e^x + 1)
substitute x for e^x + 1 in f(x)
f(g(x)) = ln (e^x + 1)
f(g(2)) = ln (e^2 + 1)
For g(f(x));
g(f(x)) = g(ln x)
substitute x for ln x in g(x)
g(f(x)) = e^lnx + 1
g(f(x)) = x+1
g(f(e)) = e+1
f(g(2))-g(f(e)) = ln (e^2 + 1) - (e+ 1)
