2/5 would be since it is closer because it is by 0.4 which means it would be closer to 0.5 by 0.1. So since it's by 0.4 and there is only 0.1 to make 0.5 the answer is 2/5. Also just saying are you still an active account?
Answer
Find out the speed of the boat in still water .
To proof
Let us assume that the speed of the boat in still water be u .
As given
The speed of a stream is 4 mph
hence
speed upstream = u - 4
speed downstream = u + 4
Formula
As given
A boat travels 8 miles upstream in the same time it takes to travel 16 miles downstream.
First case for the upstream
Second case for the downstream
now compare the equations
simplify the equation
8( u +4 ) = 16 (u -4)
8u +32 = 16u - 64
8u = 96
u = 12 mph is the speed of the boat in still water .
Hence proved
The speed of the stream = 4 mph.
Let us assume speed of the boat in still water = x mph.
Total speed upstream = (x-4) mph.
Total speed downstream = (x+4) mph.
We know, time, speed and distance relation.
Time = Distance / Speed.
Total time taken upstream = 8 / (x-4)
Total time taken downstream = 16/(x+4).
Time taken upstream = time taken downstream.
Therefore,
8 / (x-4) = 16/(x+4).
On cross multiplication, we get
16(x-4) = 8(x+4).
16x - 64 = 8x +32.
Adding 64 on both sides, we get
16x - 64+64 = 8x +32+64
16x = 8x + 96.
Subtracting 8x from both sides, we get
16x-8x = 8x-8x + 96.
8x = 96.
Dividing both sides by 8, we get
x = 12.
The number 10 increased by 6 and then doubled equals 32.
To express the situation where a number (x) is increased by 6 and then the sum is doubled, we can write it as:
2(x + 6)
In this expression, (x + 6) represents the number increased by 6, and then multiplying the sum by 2 doubles the result.
For example, if the number x is 10, then the expression would be:
2(10 + 6) = 2(16) = 32
So, in this case, the number 10 increased by 6 and then doubled equals 32.

Answer:
2(X+6)
Step-by-step explanation:
Answer:
The answer provided is incorrect, the mistake is in the division between the monomials and that is equal to not , because we must mantain the same base "x" and subtract the expoents that are .
Step-by-step explanation:
In order to simplify that question we need to multiply, divide and power monomials with the same base "x". When we multiply monomias with the same base we sum the expoents, to divide we subtract the expoents and to power them we multiply the expoents. Therefore to simplify the equations we must do:
The answer provided is incorrect, the mistake is in the division between the monomials and that is equal to not , because we must mantain the same base "x" and subtract the expoents that are .
Answer:
No the answer is incorrect.
Step-by-step explanation:
From the question given;
( . / )¹/²
We will start by solving the inner bracket
By the law of indices
. =
we will replace . by
. by
( . / )¹/² = ( / )¹/²
By the law of indices
/ = =
We will replace / by
( / )¹/² = ( )¹/² = =
( . / )¹/² =
No the answer is incorrect.
He made a mistake, because / = = = and not equal to
Each turtle gets 3.11 ounces if Each of the 27 turtles in the pet store needs to be fed
Fraction number consists of twoparts, one is the top of the fractionnumber which is called the numerator and the second is the bottom of the fractionnumber which is called the denominator.
We have:
Each of the 27 turtles in the pet store needs to be fed.
There is one bag of turtle food that weighs 84 ounces.
Each turtle gets the food = 84/27
= 3.11 ounces
Thus, each turtle gets 3.11 ounces if Each of the 27 turtles in the pet store needs to be fed

Step-by-step explanation:
84 ounces / 27 turtles = 3.111 ounces per turtle
Or in fractional form, 3 ¹/₉ ounces per turtle.
