Your answer would be “a”.

In order to receive a positive solution in the following equation, you must include a double negative to have them cancel each other out and come up with a positive value. Sorry if this is confusing it’s easier to explain this process in person rather than online but I hope this helps anyways :)

Can u help me with (29,30,31)
Gennadij [26K]

Answer:

v = -5, t = -13. , d = -12

Step-by-step explanation:

29) 3v - 9v = 30

Simplifying gives us -6v = 30. Then dividing both sides by -6 reaches our answer of v = -5.

30)12t - 8t = -52

Simplifying gives us 4t = -52. We can divide both sides by 4 to reach a conclusion that t = -13.

31) -8d - 5d + 7d = 72

Simplifying gives us -6d = 72. We can then divide both sides by -6. In doing so, we can achieve our answer that d = -12.

What is the total area of the shape shown? All units are in feet
DedPeter [7]
First, we should calculate the areas separately.
4x8=32
5.6 x 4 = 22.4/2 = 11.2
4.5x4=22 22/2=11
4x8=32
32+11+32+11.2
64+22.2=86.2
So 86.2 ft2
Hope this helped. ^^

Answer:

B: Yes, the participants are grouped by sun exposure, and then both treatments are randomly assigned within each group.

Step-by-step explanation:

Randomized block design is one in which the experimental units are categorized into groups which we call blocks. Thereafter, treatments will be randomly allocated to the experimental units inside each of the blocks.

Now, from the question, we can see that they were grouped in Blocks according to their outdoor activity which is degree of exposure to the sun. Thereafter the individual groups are randomly assigned treatments.

Thus, Option B is correct.
