30 + 20 + 30 + 20 = 100
30 x 10% = 3 + 30 = 33
20 x 5% = 1 + 20 = 21
33 + 21 + 33 + 21 = 108
100 / 108 = 0.925925926 = 0.93 = 93%
100% - 93% = 7%
7% increase
2+2+5+7+9=25

Answer:
x = 12
Step-by-step explanation:
The mistake made here is in making 130 = 9x + 7. They are not the same.
The central angle = 130 degrees.
Any angle sharing the endpoints of the central angle and having it's vertex on the same side of the central angle is 1/2 the central angle.
1/2 the central angle = 130 /2 = 65
Cyclic quadrilaterals (those with all 4 points touching a circle's circumference) have opposite angles supplementary.
65 + 9x + 7 = 180 Combine like terms on the left
72 + 9x = 180 Subtract 72 from both sides
72 - 72 + 9x = 180-72 Combine
9x = 108 Divide by 9
9x/9 = 108/9
x = 12
Answer: 356 crates
Step-by-step explanation:
1 pound = 16 ounces
Then 160 ounces = 10 pounds
if 1 crate is of 10 pounds then 3560 pounds contains 3560/10 crates
- All the listed combination of row and boxes are correct and can be chosen from.
From the question, we are asked to find the row arrangement of a stack of boxes. Let us take a look at each one of the aforelisted answers
- x rows with 16 boxes in each row
- 8 rows with x boxes in each row
- 16 rows with x boxes in each row
Since we are told that the total number of boxes to be stacked is 64, then for the first arrangement, we can deduce that the "x" is going to be 4. This is because multiplying 4 by 16 gives 64. For the second row, using the same calculation, we find that "x" is 8. And that of the third gives our "x" to be 4 as well. We can then adjudge that;
- 4 rows with 16 boxes in each row
- 8 rows with 8 boxes in each row
- 16 rows with 8 boxes in each row
Bearing this in mind, we can see that each of the 3 answers fits into the requirements we are asked.
- At least 3 rows, and at least 4 boxes in each row.
Hence, all of the options are correct.
