Answer:
4.5.
Step-by-step explanation:
4.92 +2.18 x 7.31
= approximately 5 + 2 * 7.5
= 20
Now 4.5 * 4.5 = 20.25 so:
The estimate for the square root is 4.5.
BTW,
KEY:
• exponents are going to be written as “^(x)”.
• if I put “huh” or “nope” or “what” (etc.) that means I don’t know how to solve it.

25. 4a^(2)+2a+2b+3
Answer:
C. a = 6
Step-by-step explanation:
Use the Pythagorean theorem

+ 64 = 100
= 36
a = 6
<span>The proportion of clay uses is 3/8 (Three Eighths). That is 3 lbs. of clay to every 8 vases. This is determined by the first given proportion 3 lbs./8 vases and confirmed by the second. To prove that is the case you divide the second ration by the first numerator:
9 divided by 3 = 3 and 24 divided by 3 = 8. So the proportion for 9/24 is still 3/8. This can also be used to increase the number of vases made. For example if 40 vases need to be made:
we divide 40 by the numerator 8 = 5. So we need 5 portions of 3 to make 40 vases. 5 times 3 = 15. So the 15 lbs. of clay is needed for 40 vases.</span>
