Answer:

x = 100

Step-by-step explanation:

The sum of the opposite interior angles of a triangle is equal to the exterior angle

x+15 = 115

Subtract 15 from each side

x+15-15 = 115-15

x = 100

I believe there’s 52 weeks in a year besides leap year so it would be 52 divided by 2 times 10 and you’d have your answer

Quick brainliest asap!! sin^-1 (1.1976) SHOW YOUR WORK so I can see if it makes sense!!

Answer:

no solutions

Step-by-step explanation:

We want to find $\theta$ such that $\theta=\sin^{-1}(1.1976)$ .

We can take the sine of both sides of the equation to get $\sin(theta)=\sin(\sin^{-1}(1.1976))=1.1976$ .

We know that the range of the sine function goes from -1 to 1 inclusive, so there is no value $\theta$ such that $\sin{\theta}>1$ .

Therefore, the answer is $\boxed{no~solutions}$ and we're done!

The sequence forms a Geometric sequence as the rule to obtain the value for the next term is by ratio

Term 1: 1000
Term 2: 200
Term 3: 40

From term 1 to term 2, there's a decrease by $\frac{1}{5}$
From term 2 to term 3, there's a decrease also by $\frac{1}{5}$

The rule to find the $n^{th}$ term in a sequence is
$n^{th}=a r^{n-1}$ , where $a$ is the first term in the sequence and $r$ is the ratio

So, the formula for the sequence in question is
$n_{th}$ term = $1000( \frac{1}{5} ^{n-1} )$

The sequence is a divergent one. We can always find the value of the next term by dividing the previous term by 5 and if we do that, the value of the next term will get closer to 'zero' but never actually equal to zero.

We can find a partial sum of the sequence using the formula
$S_{∞} = \frac{a}{1-r}$ for -1<r<1
Substituting $a=1000$ and $r= \frac{1}{5}$ we have
$S_{∞}$ = $\frac{1000}{1- \frac{1}{5} }$ = 1250

Hence, the correct option is option number 1
