Answer:
The score on the next test must be between 86 and 98, inclusive
Step-by-step explanation:
Write an inequality using the average:
86 ≤ ≤ 90
Solve for x:
multiply everything by 3:
258 ≤ x + 83 + 89 ≤ 270
258 ≤ x + 172 ≤ 270
subtract 172 from everything:
86 ≤ x ≤ 98
The score on the next test must be between 86 and 98, inclusive
Answer:
2.34x10↑-3 +4.56x10↑-2 = 0.234x10↑-2 + 4.56x10↑-2 = 4.794x10↑-2
the length of YZ that is rounded to 3 significant figures using XY = 3.2cm. XZ = 1.7cm is 1.50 cm
Explanation :
Given : XY = 3.2cm. XZ = 1.7cm.
We need to calculate the length of YZ
From the given information we can see that Z lies between X and Y
So we add XZ and ZY to get XY
Substitute the given values and solve for YZ
Round the answer to 3 significant figures.
After rounding to 3 significant figures , the length of YZ=1.50 cm
