Answer:
- <em>Between which two tens does it fall?</em><em> </em><u>Between 25 and 26 tens</u>
<em><u /></em>
- <em>Between which two hundreds does it fall?</em> <u>Between 2 and 3 hundreds</u>
Explanation:
The place-value chart is:
Hundreds Tens Ones
2 5 3
<em><u /></em>
<em><u>a) Between which two tens does it fall? </u></em>
Using the place values you can write 253 = 25 × 10 + 3, i.e. 25 tens and 3 ones.
From that you can write:
Then, you conclude that 253 is between 25 and 26 tens.
<u><em>b) Between which two hundreds does it fall?</em></u>
Using the same reasoning:
- 253 = 2 × 100 + 5 × 10 + 3 = 253
Conclusion: 253 is between 2 hundreds and 3 hundreds.
Answer:
166 2/13 deg
Step-by-step explanation:
The sum of the measures of the interior angles of a convex polygon of n sides is 180(n - 2).
A hexagon has 6 sides, so n = 6.
sum of measures of angles = 180(n - 2) = 180(6 - 2) = 180(4) = 720
4x + 5x + 6x + 7x + 8x + 9x = 720
39x = 720
x = 720/39
x = 240/13
The largest angle has measure 9x.
9x = 9 * 240/13 = 2160/13
2160/13 = 166 2/13
Answer: 166 2/13 deg
Answer:
Option C
10%
Step-by-step explanation:
Given information
Cost of investment=$20000
Selling price=$22000
Profit=Selling price-Cost of investment=22000-20000=2000
Return on investment=profit/cost of investment
Answer:
The middle slab is 2 cubic feet.
Step-by-step explanation:
The problem presents the information: Mr. Alvarez makes a walkway out of 3 cement slabs.
However, he uses 14 Cubic feet of cement to make the walkway. Each square slab has a volume of 4 cubic feet.
Mr. Alvarez makes the way with 3 cement slabs (NC), each cement slab is 4 cubic feet (UC). It means, the cubic feet for the 3 cement slabs (CS) are:
CS = NC* UC = 3*4 = 12 cubic feet.
It means Mr. Alvarez uses 12 cubic feet with 3 cement slabs.
Mr. Alvarez used in total of 14 cubic feet of cement (TC). At this moment he used 12 cubic feet of cement (CS). It means, there will be a part of the cement slab used (PC).
PC = TC - CS = 14 - 12 = 2 Cubic feet.
Finally, the middle slab is 2 cubic feet of cement.
It increases at T because the behavior increased its speed
