To solve the first question, the angles J and K are perpendicular to each other, that means also that the angles are 90 degrees.
Apart from each other.
This is the total angle measure, that means the sum of the smaller angles must equal 90 degrees.
So the expression would be
2x - 9 + 27 = 90
2x + 18 = 90
2x = 90 - 18
2x = 72
X = 72/2 = 36 degrees.
For the second question since w and v are parallel that means the angles are equal to each other
Thus make the expressions and value equal to each other and solve for x
3x + 60 = 120
3x = 60
X = 20 degrees.
Answer:
240 cubic feet
Step-by-step explanation:
l×w×h
12×4=48
48×5=240
Answer:
No.
Step-by-step explanation:
This type of problem is actually a trick problem. The question indicates that the PRODUCT of 3.93 and 0.07 would be about 4. The question is referring to the answer of the two values Multiplied to each other.
To visualize the question, we have:
3.93 x 0.07
This would give us:
0.2751
Kerri would be correct if she was looking for the SUM of the two values.
This would be:
3.93 + 0.07
This would give us:
4
Therefore in trick problems like this ones, it is better to look at what exactly is being asked.
So, we have to see which perfect squares
is in between.
Through guess and check, we see that
, which evaluate to 289 and 324 respectivly, if under a radicand, would be the two perfect squares closet to the square root of 300.
That means if we were to take the square root of 289 and 324, we should have the two integers that the square root of 300 is in between, and we see that those two numbers are 17 and 18.
Answer:25% off would be the better option
