Answer:
3
Step-by-step explanation:
The net of a cube consists of 6 squares which when folded form a cube. To form the net of a cube 4 of the face must be in line with two faces not aligned. This will allow the cube to have 4 sides and a top and bottom. Choices 1, 2, and 4 all have fours faces aligned with two faces not aligned. Choice 3 does not. This does not form a cube.
Answer:
A.88°
Step-by-step explanation:
Given,
RT is the diameter of the circle with center Q.
We have to find the measure of ∠RQS.
Solution,

Since RT is the diameter. That is it makes a straight angle at the center Q.
And measure of straight angle is 180°.
So we can say that ∠RQS and ∠SQT makes a straight angle.

Now substituting the given values, we get;

We get the value of 'x'.
By substituting the value of x, we can find the measure of ∠RQS.


Hence the measure of ∠RQS is 88°.
The probability of picking a pear is 3 in 10
2/5x+y=7
subtract 2/5x on both sides
y=-2/5x+7
The answer is B. The probability should approach 0.5 as the number of samples increase.
