Answer:
7 x 4 = 28
28 x 1/2(dividing by 2) = 14, 14 x 2(two triangles) = 28
4 x 5 = 20(area of square in the middle)
5 x 8 = 40(area of square on one side), 40 x 2 = 80(area of squares on both sides)
Now lets add the given areas:
28 + 20 + 80 = 128 square is your answer.
57°
Step-by-step explanation:
angle of RAD is the double of RBD
To solve first move the 98 to the other side by subtracting it from both sides. Then divide by - 1 on both sides to that the x^2 is no longer a negative. You are left with:

Now square root both sides to get

The two factors that make up 98 are 49 and 2. 49 can be square rooted. So we are left with these answers:

Answer:
Option A. The average number of crisps per can of Pringles is less than 100.
Step-by-step explanation:
We are given that the member of consumer group is wants to determine whether the average number of crisps per can of pringles is less than the average number of crisp mentioned in an advertisement whereas average number of crisp mentioned in an advertisement are 100 crisps per can. We know that the null hypothesis always contains equality and alternative hypothesis is contrary to the null hypothesis. Thus, the alternative hypothesis would be that the average number of crisps are less than 100 per can. So, the formed hypothesis are
Null hypothesis: The average number of crisps per can of Pringles is 100.
Alternative hypothesis: The average number of crisps per can of Pringles is less than 100.
