Answer:
6 minutes
Step-by-step explanation:
Speed of net = 15mbps
Time taken = 4min.
Total size of application= 15*60*4= 3600mb
Now speed = 10mbps
Time taken = 3600/10
= 360 sec = 360/6 min
= 6 min

Fcator: x^2-18x+72=0
*work please*
Answer:
x = 12, 6
Step-by-step explanation:
Factor using the AC method.
Consider the form x² + bx + c. Find a pair of integers whose product is c and whose sum is b . In this case, whose product is 72 and whose sum is -18.
-12, -6
Write the factored form using these integers.
(x - 12)(x - 6) = 0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
x - 12 = 0, x = 12
x - 6 = 0, x = 6
i hope this helps, good luck :)
anyone tell me the answer
Answer:
a. Pop
b. 30 CDs
c. 230 CDs
Step-by-step explanation:
Given that "O" represents 20 CDs
a. The CD that was the mode is the CD that has as much "O", which is Pop.
Mode = Pop
b. Number of Rock CDs = 3 × 20 = 60 CDs
Number of Classical CDs = 1½ × 20 = 30 CDs
Therefore, 30 more CDs of Rock were sold than Classical CDs were sold
c. Pop = 5*20 = 100 CDs
Jazz = 2*20 = 40 CDs
Classical = 1½*20 = 30 CDs
Rock = 3*20 = 60 CDs
Total sold altogether = 100 + 40 + 30 + 60
= 230 CDs

Answer:
y = 3/2x + 5/2
Step-by-step explanation:
If , then what is mto the nearest degree?
Answer:
70 degrees
Step-by-step explanation:
If cosm<A = 342/1000, we are to find the value of a
Take arccos of both sides
cosm<A = 342/1000
cosm<A = .342
arccos(cosm<A) = arccos(0.342)
m<A = arccos(0.342)
m<A = 70 degrees
Hence the measure of m<A is 70 degrees
For each parallelogram below, find the value of x.
Will give brainliest for full answer
Answer:
x = 3 and x = 8
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, then
WA = DR , substitute values
12x - 9 = 5x + 12 ( subtract 5x from both sides )
7x - 9 = 12 ( add 9 to both sides )
7x = 21 ( divide both sides by 7 )
x = 3
------------------------------------------------------
The diagonals of a parallelogram bisect each other, then
QS = [tex]\frac{1}{2}[/tex] QT , that is
8x - 14 = [tex]\frac{1}{2}[/tex] × 100 = 50 ( add 14 to both sides )
8x = 64 ( divide both sides by 8 )
x = 8

Cosx=4/5 what is sin2x cos2x and tan2x
Answer:
-24/5
Step-by-step explanation:
The solution to the problem is as follows:
cscx < 0 means 1/sinx < 0, or sinx < 0.
sinx = -3/5 because you're dealing with a 3-4-5 triangle, and we established
sinx is negative.
sin2x = 2sinxcosx = 2*-3/5*4/5 = -24/25
cos(2x) = cos^2(x) - sin^2(x) = 16/25 - 9/25 = 5/25 = 1/5
tan2x = sin2x / cos2x = -24/5

Step-by-step explanation:
Hannah spends $4.50 each day to buy lunch at her school. After school each day, she buys the same snack. Hannah spends $28.75 for lunch and snacks each week. The equation and solution model the situation.
5 (4.50 + x) = 28.75; x = 1.25
What does the solution, x = 1.25, represent?
the total cost of snacks for the week
the cost of each snack
the total amount of lunch for the week
the amount she spends each day for lunch and snack
Answer:
The cost of each snack
Step-by-step explanation:
Because if we are using what makes sense and what doesnt it would not be that much for lunch each week and it wouldnt be for the day so it must be the cost of each snack
Answer:
Step-by-step explanation:
B, the cost of each snack
Why is it a problem to find the square root of a negative number, for example √-4?
Answer:
It is not possible because no number times itself can equal a negative number.
Answer:
Taking the square root of a negative number is a problem because this technically does not follow the rules of a square root. A square root is made of a number times itself, and therefore, is impossible to have a negative times a positive to make a negative total (An example would be √4, as the answer can be 2 (because 2 x 2 = 4) or -2 (because -2 x -2 = 4)).
This means that in order to solve √-4, you must use imaginary numbers. This is represented by "i."
For the example of √-4, your answer would be 2i. These imaginary numbers are used whenever you are square rooting a negative number in order to show that it is breaking the real rules of roots.

the mean temperature for the first 4 days in January was - 4 degrees the mean temperature for the first 5 days in January was - 6
degrees what was the temperature on the 5th day
Answer: The temperature on the 5th day is -14 degrees.
Step-by-step explanation:
If we have a set of N values:
{x₁, x₂, x₃, ..., xₙ}
The mean value of this set is:
M = (x₁ + x₂ + ... + xₙ)/N
Now, we know that the mean temperature for the first 4 days of January is -4°
Then if the temperatures for the first four days are {T₁, T₂, T₃, T₄}
We have:
M₄ = (T₁ + T₂ + T₃ + T₄)/4 = -4°
Where we can replace (T₁ + T₂ + T₃ + T₄) by K
Then:
K/4 = -4°
K = -4°*4 = -16°
Is the sum of the temperatures for the first four days.
Now when we consider the first 5 days, the mean is -6°, and let's define T₅ as the temperature of the fifth day, then we get:
M₅ = -6° = (T₁ + T₂ + T₃ + T₄ + T₅)/5
And we know that:
(T₁ + T₂ + T₃ + T₄) = K = -16°
We can replace that in the above equation to get:
M₅ = (-16° + T₅)/5 = -6°
Now we can solve this for T₅
(-16° + T₅) = 5*(-6°) = -30°
T₅ = -30° + 16° = -14°
T₅ = -14°
The temperature on the 5th day is -14 degrees.

A number between 10 and 20 is both a foctor of 60 and
a multiple of 6.
What is the number?
Answer:
12
Step-by-step explanation:
List out factors of 60 =
1 x 60 = 60
2 x 30 = 60
3 x 20 = 60
4 x 15 = 60
5 x 12 = 60
6 x 10 = 60
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60 are factors of 60.
List out multiples of 6 from 10 to 20.
12 and 18.
Since 12 is seen on one of the factors of 60 and a multiple of 6 between 10 and 20, the answer is 12.
