It would make 5 complete frames, and about 8/10 of another frame.
108 / 18.375 = 5.8&*)&^&%*$*
I used a calculator.
You could keep adding 18 and 3/8 over and over again until you get right under 108 if you're good at math like me, but most people would have to add 18 and 3/8 separately.

Thanks, and if you liked my answer, please consider giving me the brainliest answer, because I need 5 of them to get to the next level.

Namely, how many times does 18 and 3/8 go into 108?

\bf \cfrac{108}{18\frac{3}{8}}\implies \cfrac{108}{\frac{18\cdot 8+3}{8}}\implies \cfrac{108}{\frac{147}{8}}\implies \cfrac{\frac{108}{1}}{\frac{147}{8}}\implies \cfrac{108}{1}\cdot \cfrac{8}{147}
\\\\\\
\cfrac{36\cdot \underline{3}}{1}\cdot \cfrac{8}{\underline{3}\cdot 49}\implies \cfrac{288}{49}
\\\\\\
\textit{49 goes into 288 \underline{5 times}, with a \underline{remainder} of 43}\implies 5\frac{43}{49}

Find the distance between the pair of points. Round your answer to the nearest hundredth. (-8,19) and (3,5)
Amiraneli [1.4K]

Answer:

<h3>The answer is 17.80 units</h3>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-8,19) and (3,5)

The distance between them is

d =  \sqrt{ ({ - 8 - 3})^{2}  +  ({1 9 - 5})^{2} }  \\  =  \sqrt{( { - 11})^{2}  +  {14}^{2} }  \\  =  \sqrt{121 + 196}  \\  =  \sqrt{317}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 17.804493...

We have the final answer as

<h3>17.80 units to the nearest hundredth</h3>

Hope this helps you

One x-intercept for a parabola is at the point (-2,0).
BARSIC [14]
You can find the x intercept by setting y to 0 and factor the equation.

0=2x^3+3x-2
0=(2x-1)(x+2)

We can make this equation =0 if x is -2 and 1/2.

So the x intercepts are (-2,0) and (0.5,0)

Consider the following: A medical researcher wants to determine the effects of pH (a measure of alkalinity or acidity, with pure
natita [175]

Answer:

See below

Step-by-step explanation:

<h3>Continuation of the question</h3>

<u>Data in the table:</u>

<u>PH             4       5     6     7     8    9     10     11 </u>

<u>Bacteria    116   120  131  136  141  151  148   163</u>

  • <em>Create a scatter plot to represent the data: Based on the data and your scatter plot, what do you think a good linear function would be to represent the data?</em>
<h3>Solution</h3>

<em>See attached for scatter plot</em>

We can see the chart is close to linear function. Let's build one based on data in the table

<u>The line will be in the form of:</u>

  • y = mx + b

<u>If we use two points and get the equation</u>

  • (4, 116) and (8, 141)

<u>Finding the slope:</u>

  • m = (141-116)/(8-4) = 25/4 = 6.25

<u>Then, finding y-intercept:</u>

  • 116 = 6.25*4 + b
  • b = 116 - 25 = 91

<u>So the line is:</u>

  • y = 6.25x + 91

<em>Note: This is approximate best fit graph and it is attached as well. Exact formula for the line is built by using different method and is very close to the one above</em>
