Answer:
the answer is -5< x
Step-by-step explanation:
you you start by subtracting 7 by both sides leaving you with -20<4x. then then divide both sides by 4 leaving you with -5< x
Answer:
Total walk she did around the pool every morning = 141.3
Step-by-step explanation:
Given - Kriti has a circular swimming pool in her house. The radius of the swimming pool is 22.5 cm. She walks one round every morning before diving in the pool.
To find - How far does she walk around the pool every morning?
Proof -
Given that, the swimming pool is circular in shape.
So,
1 round of circle = Circumference of circle.
As we know that,
Circumference = ![2\pi r](https://tex.z-dn.net/?f=2%5Cpi%20r)
= ![2*\pi *22.5](https://tex.z-dn.net/?f=2%2A%5Cpi%20%2A22.5)
= 141.3
∴ we get
Total walk she did around the pool every morning = 141.3
Answer:
c is the correct option of the question
to get the slope of any straight line, we simply need two points off of it.
so from what I can tell in the graph, check the picture below, the line goes above the 4 about 3/4 pretty much, or namely 0.75 above the 4, that'd make it 4.75, the graph also goes below the -3, about 1/4 below, namely 0.25 that'd make it -3.25, because two grid lines make up a whole number, so let's use those two points to get its slope.
![(\stackrel{x_1}{-2}~,~\stackrel{y_1}{-3.25})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{4.75}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{4.75}-\stackrel{y1}{(-3.25)}}}{\underset{run} {\underset{x_2}{2}-\underset{x_1}{(-2)}}} \implies \cfrac{4.75 +3.75}{2 +2}\implies \cfrac{8}{4}\implies \text{\LARGE 2}](https://tex.z-dn.net/?f=%28%5Cstackrel%7Bx_1%7D%7B-2%7D~%2C~%5Cstackrel%7By_1%7D%7B-3.25%7D%29%5Cqquad%20%28%5Cstackrel%7Bx_2%7D%7B2%7D~%2C~%5Cstackrel%7By_2%7D%7B4.75%7D%29%20%5C%5C%5C%5C%5C%5C%20%5Cstackrel%7Bslope%7D%7Bm%7D%5Cimplies%20%5Ccfrac%7B%5Cstackrel%7Brise%7D%20%7B%5Cstackrel%7By_2%7D%7B4.75%7D-%5Cstackrel%7By1%7D%7B%28-3.25%29%7D%7D%7D%7B%5Cunderset%7Brun%7D%20%7B%5Cunderset%7Bx_2%7D%7B2%7D-%5Cunderset%7Bx_1%7D%7B%28-2%29%7D%7D%7D%20%5Cimplies%20%5Ccfrac%7B4.75%20%2B3.75%7D%7B2%20%2B2%7D%5Cimplies%20%5Ccfrac%7B8%7D%7B4%7D%5Cimplies%20%5Ctext%7B%5CLARGE%202%7D)
The answer is 7.7272727273
what you do is divide 11 into 85
