You can kayak around Hamilton island in 3 hours. Kayaking together, you and your friend can kayak around the island in 1.4 hours. Let t be the time (in minutes) your friend would take to kayak around the island alone. Write and solve an equation to find t.
Answer:
1 / 180 + 1 / t = 1/84
t = 157.5 minutes
Step-by-step explanation:
3hrs = 180 minutes
1.4 hours = 84 minutes
your rate + friend's rate = rate together
1 lap in 180 min + 1 lap in t min = 1 lap in 84 min
The equation is
1 / 180 + 1 / t = 1/84
subtract 1/180 from both sides
1/t = 1/84 - 1/180
1/t = 0.006349206349
multiply both sides by t
1 = 0.006349206349t
Divide both sides by 0.006349206349
1 / 0.006349206349 = t
157.5 = t
t = 157.5 minutes
please solve thank you

Step-by-step explanation:
For the function: f(x) = 3x^2 +5x – 8, find and simplify
A. f(x) - f(a) divided by x-a
b.f(x +h) - f(x) all divided by h
Answer:
[tex]f(x) = 3 {x}^{2} + 5x - 8[/tex]
[tex]f(x + h) = 3 ({x + h})^{2} + 5(x + h) \\ = {3x}^{2} + {3h}^{2} + 6xh + 5x + 5h - 8 \\ [/tex]
answer will be 6x+5

Is 1 greater in 31788 or 188743
Answer: 188743
Step-by-step explanation:
It's in the "hundred thousand" place.
Answer: 188743
Step-by-step explanation:
Using our knowledge of digit placements, we determine that the 1 in the 31788 is in the thousands digit and the 1 in 188743 is in the hundred-thousands digit.
Therefore, using our knowledge of digit placements, we determine the answer is 188743.

A Tenth of a number is the value that we get when we divide the number by 10. Similarly, Hundredth is the value we get when it is divided by 100.
Answer:
20
Step-by-step explanation:
2/10 = x/100 -> both sides times 100
20 = x
Can someone please help, I will give brainiest. If possible explain please.
Step-by-step explanation:
The angles (8x + 28) and (4x - 7) are supplementary to each other so we can write
[tex](8x + 28) + (4x - 7) = 180 \Rightarrow 12x + 21 = 180[/tex]
or
[tex]x = 13.25[/tex]
Also, note that the angle (4x - 7) and [tex]\angle{TQS}[/tex] are vertical angles, which means that they are equal to each other. Therefore,
[tex]\angle{TQS} = 4x - 7 = 4(13.25) - 7 = 46°[/tex]
Find (f•f)(3)
f(x)=x^-x
Answer:
approximately 1.13
Step-by-step explanation:
[tex](f \circ f) = f(f(3))[/tex]
Working from the inside...
[tex]f(3) = 3^{-3} =\frac{1}{3^3} = \frac{1}{27}[/tex]
Now put this result back into f again.
[tex]f(\frac{1}{27})=\left(\frac{1}{27}\right)^\frac{1}{27}[/tex]
Use a calculator to approximate this; the result is 1.13.
Note: an "exact" answer is [tex]\frac{1}{\sqrt[27]{\frac{1}{27}}}[/tex].

In a horse race, how many different finishes among the first 3 places are possible if 7 horses are running? (Exclude ties)
There are a possible___different finishes.
Answer:
7 x 6 x 5 = 210
Step-by-step explanation:
its a combination's problem.
7 horses are eligible for first place.
6 of those are eligible for 2nd given that one of the 7 finished first.
similarly 5 of the remaining are eligible for 3rd place given 2 horses have taken the first 2 spots.
therefore 7 x 6 x 5 possible combinations = 210 combinations.

expression that shows that the total number of CDs sold both ddays. Rewrite
your answer using the Commutative Property of Addition
9514 1404 393
Answer:
= x + y + 20
Step-by-step explanation:
There are a couple of ways you could write this.
friend sales + your sales
= (14 +x) +(y +6)
= (x +14) +(6 +y) . . . . commutative property used twice
= x +14 +6 +y = x +20 +y
= x + y + 20 . . . . . . . commutative property used again
__
first-day sales + second-day sales
= (14 +y) + (x +6)
= (y +14) +(6 +x) . . . . commutative property used twice
= y +14 +6 +x = y +20 +x
= y +x +20 . . . . . . . . commutative property used again
= x + y + 20 . . . . . . . and again

Please explain step by step to get marked!
It moved forward 4 yards, then back 10 yards:
4-10 = -6
It is now -6 yards from where it started.
It then moved 2 yards forward from there:
4-6 + 2 = -4
The ball finished -4 yards from the original location.

Hi! Can anyone help please, I have been trying this problem for the past hour and I got slope-intercept equation like this but I don't know what to do y=1/2x+5
The graph of a function g is shown below. Find the following:
g(10)
Answer: 8
Step-by-step explanation:
A really simple way to solve these problems is to think of g(whatever number) as the y coordinate on your graph. Therefore the question is basically asking you if x is 10, what is y. If we find 10 on the x axis, we can count up the y axis until we reach the line. So, the answer is 8
Yes you found it correct as per slope intercect form y=mx+b
Here
y=1/2x+5Slope=m=1/2
Y intercect=5
Now.
for g(10)
The coordinate is (10,8)
So
g(10)=8
