The ratio of the surface areas of 2 rectangles is 256:484. What is the ratio of their heights?
Answer:
182:242
Step-by-step explanation:
Reduce the ratio by its halves (50 percent) and simplify.
Although for this case, you could reduce it even further, because this is a ratio, not the true height.
If this is a test, I would not recommend that.
what is the unknown fraction 4/10 + _____ = 73/100
Answer: the answer is 33/100 or .33
Answer:
33/100
Step-by-step explanation:
Because since 4/10 + ?= 73/100 that means the denominator get's change so we know that the demonter for the ? number had to have 100 as a denominator.
And since that number has a 100 for their demonter that means we times our demonter(10 until it get's to 100 so how many times do we times 10 to it get's to 100? the answer is 10.
So since we times our denominator we also have to times our numerator by 10 as well what is 4 times 10? Our answer is 40.
So now our fraction 4/10 is now 40/100. what= 73 when you add it to 40?
Our answer for that is 33 how I know is 40+ 33= well lets add the tens what is 40 + 30=70 now add ones 3 so 73 and our denominator is already the same and our fraction now is 73/100. and there's our answer.
4/10(40/100 now because of the calculations) + 33/100=73/100 so we figured out our mysterious fraction| Mysterious fraction=73/100.
Hope this helps have a magnificent day:)
On Nick's playlist, 5/12 of the songs are pop. What fraction of the
songs, n, are NOT pop?
How can you draw a picture and write an equation to
represent the problem?
Answer:
7/12
Step-by-step explanation:
Draw a rectangle with 12 squares. 5 of them will be pop and 7 will not.
The equation will be 12/12 = 5/12 + n. You will subtract 5/12 from each side and get 7/12 = n.
a family buys 5 airline tickets online. The family buys travel insurance that costs $17 per ticket. The total cost is $1,495. Let x represent the price of one ticket. Write an equation for the total cost. Then find the price of one ticket.
Answer:
$282
Step-by-step explanation:
The price per ticket can be found by dividing the total cost by the number of tickets, then subtracting the value of any per-ticket add-ons.
5(x +17) = 1495 . . . . . total cost of 5 tickets with 17 per ticket ins charge
x +17 = 299 . . . . . . divide by 5
x = 282 . . . . . . . price of 1 ticket
The price of one ticket is $282.
how to find the missing side of a triangle in trig for geometry
Step-by-step explanation:
cosine is cos(angle)= adjacent/hypotenuse
sine is sin(angle) = opposite/hypotenuse
Tangent is tan(angle)= opposite/adjacent
for all of those
if the equation is something like tan(69)= x/69
multiply both sides by 69 so it will end up as x=69tan(69) and put that in the calculator
if it is something like tan(69)= 69/x
just swap x and tan(69)
it is much easier
it will then be 69/tan(69) and put that in the calculator

1. A bottling company uses a machine to fill the bottles with olive oil. These bottles are
designed to contain 475 millilitres (ml). In fact, the contents vary according to a normal
distribution with a mean of 473 ml and standard deviation of 3 ml. A) What is the distribution, mean, and standard error of the sample mean of six randomly
selected bottles?
Using the Central Limit Theorem, it is found that the distribution of the sample mean of six randomly selected bottles is approximately normal, with mean 473 ml and standard error of 1.22 ml.
Central Limit TheoremThe Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
In this problem, for the population, we have that:
[tex]\mu = 473, \sigma = 3[/tex]
Then, for the sample of n = 6:
[tex]s = \frac{3}{\sqrt{6}} = 1.22[/tex]

An item at a consignment shop is marked down 10% each week until it sells. A dress originally priced at $150 sells during the seventh week
Answer:
I'm guessing the question asks us what is the current balance of the dress after 7 weeks.
So it if drops by 10% every week, we need to find how much it went down one week;
consider 10% as 10/100 in fraction form;
10/100 x 150 = $15, it goes down by $15 each week, but we need to find how much 7 weeks would be:
7 x $15 = $105, it went down $105 so we need to subtract that from the total:
150 - 105 = $45, it would now be currently up for sale for $45.

What is the reflection of the point (-5,2) in the line y=2?
Answer:
-2/5
Step-by-step explanation:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

The sine and cosine are related to the definitions because of the identity [tex]\cos^{2}\theta + \sin^{2}\theta = 1[/tex].
How cosine and sine are related in the unit circleThe unit circle is a particular case of the Pythagorean theorem, in which hypotenuse ([tex]r[/tex]) has a measure of a unit. That is:

And by trigonometric relations, we have the following formula:

- solve the system using elimination....
x - 3y = -11
-x + 2y = 7
We minus these equations : x - 3y - (-x + 2y) = -18
= x - 3y + x - 2y = -18
2x - 5y = -18
Now, we add these equations :
x - 3y = -11
-x + 2y = 7
-> x - 3y - x + 2y = -4
-y = -4
y = 4
Replace it in 2x - 5y = -18
2x - 20 = -18
2x = -18 + 20 = 2
x = 1
Recheck : 1 - 3 x 4 = -11
-1 + 8 = 7.
