=-11

Step-by-step explanation:

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:)

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.

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.

The 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]

if you multiply 4 by 2.5, you get 10. if you multiply 10 by 2.5 you get 25!

» The diameter of a circle is 12 kilometers. What is the circle's circumference? Use 3.14.

— — — — — — — — — —

To find the circumference, use pi (π), a mathematical constant. Its value is approximately equal to 3.14.

— Multiply the diameter with π in order to get the circumference of a Circle.

Therefore, the circumference of the circle is 37.68 kilometers.

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).

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.

The sine and cosine are related to the definitions because of the identity [tex]\cos^{2}\theta + \sin^{2}\theta = 1[/tex].

The unit circle is a particular case of the Pythagorean theorem, in which hypotenuse ([tex]r[/tex]) has a measure of a unit. That is:

[tex]x^{2}+y^{2} = r^{2}[/tex]  (1)

Where:

If we divide the entire expression by [tex]r^{2}[/tex], then we have the following identity:

[tex]\left(\frac{x}{r} \right)^{2}+\left(\frac{y}{r} \right)^{2} = 1[/tex]

And by trigonometric relations, we have the following formula:

[tex]\cos^{2}\theta + \sin^{2}\theta = 1[/tex]  (2)

Step-by-step explanation:

sum of angle of quadrilateral is 360°

so,

2a+3a+4a+6a=360°

15a=360°

a = 360°/15= 24°

Now,

2a= 2×24=48

3a=3×24=74

4a=4×24=96

6a=6×24=120

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.

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
