Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

I'm not sure if my way of doing it is the way your teacher wants it solved but I would do...

150+150+x=360

so now we just have to solve the equation...

308+x=360\\x=52

ok and now before you judge me that still isn't the answer we still have to divide the 52 by 2 because 52 is the sum of both the smaller angles, so you'll get...26°

choice D

Eric bought a laptop for 664 it was marked 50 off because it was an opened product he also got a 15% discount which was taken of
Artyom0805 [142]

Answer:

The original price of the laptop is 840

Step-by-step explanation:

Here, we want to calculate the original price of a laptop, given the amount that was paid off and the discount percentage enjoyed.

Firstly, let’s add back the 50 taken off. That makes a total of 50 + 664 = 714

Now, we remember he was also given 15% off. Let the price paid be x;

The 15% of x is equal the difference between x and the 714

Thus;

15/100 * x = x - 714

15x/100 = (x-714)

15x = 100(x-714)

15x = 100x -71400

100x-15x = 71400

85x = 71400

x = 71400/85

x = 840

Which sketch shows the inverse of y=a x where a is greater than 1?
Dahasolnce [82]
Answer: The answer would be a line that is not as steep and a reflection in the line y = x.

If the a value in the equation is greater than 1, we will have a line that is steeper than the line y = x.  

Now, we we take the inverse of the line, it will have a slope that is lower than y = x.

The graphs will be reflected in the line y = x.

Try graphing y = 3x and 3y = x.

When working with scientific notation, what does a negative exponent let you know about the size of the number?
Delicious77 [7]

well, you saw it on the previous exercise, 8.25 x 10⁻⁶, it <u>looks</u> like 8.25 is some value between 1 and 10, but is not really, the 10⁻⁶ is disguising that is really much smaller than that, in fact much smaller than even 1.

Many people consider their smart phone to be essential! Communication, news, Internet, entertainment, photos, and just keeping c
g100num [7]

Answer:

a) 0.4567

b) 6 hours                      

Step-by-step explanation:

We are given the following information the question:

The battery life follows a normal distribution with

\mu = 9.75\\\sigma = 2.3

Formula:

z = \displaystyle\frac{x-\mu}{\sigma}

a) We have to find probability such that battery life exceeds 10 hours, that is,

P(X>10)

P(z > \displaystyle\frac{10 - 9.75}{2.3}) = P(z>0.1086)\\\\= 1 - P(z \leq 0.1086)\\= 1- 0.5433\\=0.4567

b) We have to find battery life such that

P(X \leq x) = 0.05\\\\P(z \leq \displaystyle\frac{x-9.75}{2.3}) = 0.05\\\\\displaystyle\frac{x-9.75}{2.3} = -1.64 \\\\x = (-1.64)(2.3) + 9.75\\x = 5.978

Here, we calculated the value of z from the normal distribution table.

So, after approximately 6 hours one should plan to recharge the phone.
