Answer:

u=0.375

Step-by-step explanation:

First we can write the equation down, -6(-4u+4)-6u=2(u-5)-8. First what you want to do is distribute -6 to (4u+4) and 2 to (u-5). This would result in 24u-24-6u=2u-10-8. Next add up all like terms and you will get 18u-24=2u-18. Next you would want to add 24 on both sides so that you get 18u=2u+6 then subtract 2u from both sides to get 16u=6. You the divide 16 on both sides to get u=0.375.

Regular hexagon FGHIJK shares a common center with square ABCD on a coordinate plane. AB || FG. Across which line can be combine

nlexa [21]

Answer: The answer is the yellow lines in the attached figure.

Step-by-step explanation: As shown in the attached figure, regular hexagon FGHIJK and square ABCD shares common centre on the co-ordinate plane and AB || FG.

We are to find the line across which the combined figure will reflect onto itself.

In the attached figure, we see two lines which are yellow in colour. We can easily detect that the figure will be reflected onto itself if these two lines acts as a mirror separately.

Hence these yellow lines are the required lines.

I need the answer to these, to be right, and you got to show the work on how you got the answer because if not I’ll get them wro

alexira [117]

A: $\frac{5}{3} = \frac{N}{12}$
Multiply both sides by 12
Answer: $N = 20$

B: $\frac{7}{2} = \frac{42}{N}$
Multiply both sides by 2, $7 = \frac{84}{N}$
Multiply both sides by N, $7N = 84$
Divide both sides by 7,
Answer: $N=12$

C: $\frac{N}{2}= \frac{50}{N}$
Multiply both sides by 2, $N = \frac{100}{N}$
Multiply both sides by N, $N^{2} = 100$
Simplify,
Answer: $N = 10 , -10$

Hope I helped you!

What is the probability of flipping a coin 85 times and getting tails 40 times or fewer? Round your answer to the nearest tenth

Ilya [14]

Answer:

C. 33.2%

Step-by-step explanation:

Number of trials n = 85

Probability of success p = 0.5

Number of successes r = 40

Use cumulative binomial probability:

P(x ≤ r) = binomcdf(n, p, r)

P(X ≤ 40) = binomcdf(85, 0,5, 40)

P(x ≤ 40) = 0.332
