If r = 24.9 and s = 18.9, find S. Round to the nearest tenth. S = 37.2° S = 38.2° S = 39.2° S = 36.2°

snow_lady [41]

$\boxed{S=37.2^{\circ}}$

<h2>Explanation:</h2>

Below has been attached a diagram with the meaning of this problem. So we have a right triangle whose <em>Opposite side (s) </em>measures 18.9 and whose <em>Adjacent side (r) </em>measures 24.9. So, these two sides are related in the following form:

$tan(S)=\frac{Opposite \ side}{Adjacent \ side}=\frac{s}{r} \\ \\ tan(S)=\frac{18.9}{24.9} \\ \\ tan(S)=0.76 \\ \\ S=arctan(0.76) \\ \\ S=37.23^{\circ} \\ \\ Rounding \ off: \\ \\ \boxed{S=37.2^{\circ}}$

Because they are similar all sides would have the same ratio.

Find the ratio of two known sides:

AD = 4

EH = 16

16/4 = 4

The larger figure is 4 times larger.

Now multiply AB by 4 to get EF:

EF = 3 x 4 = 12 cm

Which expression is equivalent to 60 Σ n=1 (2n − 1)2 ? Check all that apply.

Hunter-Best [27]

9514 1404 393

Answer:

B, D

Step-by-step explanation:

The quadratic expands to ...

(2n -1)² = (2n)² +2(2n)(-1) +(-1)² = 4n² -4n +1

The coefficients can be factored out of the sum, so ...

∑(4n²) = 4∑n² for example

The sum of 60 ones is 60:

$\displaystyle\sum_{n=1}^{60}{1}=1+1+1+\dots+1=60$

So, the sum can be written as ...

$\displaystyle\sum_{n=1}^{60}{(2n-1)^2}\\\\=\boxed{4\sum_{n=1}^{60}{n^2}-4\sum_{n=1}^{60}{n}+\sum_{n=1}^{60}{1}}\\\\=\boxed{4\sum_{n=1}^{60}{n^2}-4\sum_{n=1}^{60}{n}+60}$

Marshall compared his 8 most recent cell phone bills. They were $102, $97 $98 $102 $98 $104 $95 and 102 what was the mode cost

navik [9.2K]

Answer:

$102

Step-by-step explanation:

The word MODE is a statistical term that refers to the number in a given set of data that occurs the most.

In the above question, we are given the set of data:

$102, $97, $98, $102, $98, $104, $95 and $102

Rearranging, we have:

$95, $97, $98, $98, $102, $102, $102, $104.

The mode cost in the given data set above is the phone cost bill that occurred the most and this is $102.

$102 occurred 3 times in the data set.
