Answer:
3.000,000
Step-by-step explanation:
i think sorry if im wrong
Approximately 24000 CD's would fit in a rectangular wall with the above dimensions.
Basically estimating is rounding, im going to futher explain this with an example.
For example:
If I wanted to round a number by it's nearest tenth such as 678
(*example)
there are 70 tenths
now when you are estimating when you are rounding to the nearest number if the number has a higher value then 5 you increase the number if it is lower than 5 you STAY the same.
now
678,
since the number next to it is 8, 7 increases and everything else turns into zero. so 678 rounded to the nearest 10th
is 680!
Hope this example helped!
Answer:
214.08 cm²
Step-by-step explanation:
To find the whole area of an irregular polygon, you must first break it into polygons that are findable. For this figure, we can break it up into two figures, a triangles and a rectangle. To find the triangle, we must first find the height of it. To get that, we take the length of the blue line (the height of the entire figure), and subtract the height of the rectangle (9.6 cm) to get a height of 5.7 cm for the triangle. the area formula for a triangle is 1/2 of the base multiplied by the height. To get the base of the triangle, we add the base of the rectangle to the parts of the triangle that hang past it (6.2 cm in total). 6.2 + 12.8 gives us 19 cm. Now we have (19 x 9.6) divided by 2 to give us 91.2 cm². The area formula for a quadrilateral is just the base (12.8 cm) multiplied by the height (9.6 cm), to give us 122.88 cm². Add the area of the rectangle to the area of the triangle to get our answer, 214 cm².
*So sorry for the first answer, my bad.
Answer:
pens are 12
batteries are 5
Step-by-step explanation:
y=27-3x y=17-x
<u>-17 +3x</u> 27-3x=17-x <u>-17 +3x</u>
2x=10
x=5
y=27-3x y=27-3(5) y=27-15
y=12
