Sarah you failure why are you playing cricket. 

But anyway, Sarah should score 75 runs in her sixth inning to reach an average of 50. To solve, first multiply 45 by 5 to reverse the division used to find her previous average. You should get 225. We want the score added to 225, the addend of them being divided by 6 to get 50, her average. Continue by putting your variables into an equation, then simplifying. Below, I distributed the division of the 6, then subtracted 37.5 from both sides of the equation, and finally multiplied both sides by 6 to get our final answer, a score of 75. 

(225 + x)/6 = 50 

37.5 + x/6 = 50  

x/6 = 12.5 

x = 75

a cell phone company charges a monthly fee plus a 0.35 for text messages sent they charge 25.00 monthly fee and your bill is 58.
riadik2000 [5.3K]
Hey,

So first we are told that they charg a fixed fee of 25:00 right?That means even if you didn’t send any text messages you still have to pay 25:00.

So first we have to subtract that 25:00 form 58.25 right?This means the rest of the bill is for text messages OK?
So he spent 33.25(this is the answer to the subtraction) on the text messages right?
And for every text he sent he was charged 0.35 right? So we have to divide 33.25 by 0.35 right?
And that gets us 95.

Now we can double check the answer by multiplieng 95 by 0.35 and adding 25.

So th answer is 95

Hope this helps !!

The western and eastern cell towers are 10 miles apart. From the
Arte-miy333 [17]

The distance of the cell phone from the western tower is 27.47 miles and from the eastern tower is 1.76 miles

<u>Explanation:</u>

<u></u>

The sketch is attached for the reference.

tan (10) = \frac{NE}{WE}

0.176 = \frac{NE}{10} \\\\NE = 1.76

tan (70) = \frac{NW}{WE} \\\\

2.747 = \frac{NW}{10} \\\\NW = 27.47

Therefore, the distance of the cell phone from the western tower is 27.47 miles and from the eastern tower is 1.76 miles

A triangular prism has a height of 6 meters and a triangular base with the following dimensions.
Novosadov [1.4K]
The value of B is 48m. squared
This is because the formula for a triangle is (length×hight÷2)

So in this case, multiply 16 and 6 to get 96. Then divide 96 by 2 to get 48m. squared
