My teacher asked me 7 x 1/5 of 19, and I got immediately stumped. My brain is mush today.

Answer:

15) x = 10.2

16) x = 22.7 and y = 44.6

Step-by-step explanation:

15) tan 52° = 13/x

x = 13/tan 52°

16) sin 90°/50 = sin 27°/x

x = 50(sin 27°)

sin 90°/50 = sin 63°/y

y = 50(sin 63°)

Answer:

803.84 in^3

Step-by-step explanation:

First of all we have to find the base area

base area = radius^2 x 3.14 = 8^2 x 3.14 = 64 x 3.14 = 200,96 in^2

the volume can be find with this formula:

V = (base area x height)/3

V = (200.96 x 12)/3 = 803.84 in^3

Answer:

Step-by-step explanation:

First we can write the equation to find the surface area of a rectangular prism[tex]A = 2(w*l+h*l+h*w)[/tex]

Now rewrite filling in variables

[tex]A = 2(3*5+8*5+8*3)[/tex]

Solve. Keep in mind the order of operations

After solving, you should get 158.

Since these measurements were done in inches, we need to add inches/in to the end.

Also, since it is area, we need to add ²

158 in²

Answer:

AC ≈ 11 cm

Step-by-step explanation:

i used the pythagorean theorem twice . . .

1st was with ΔCED:

EC² + 7² = 8²

EC² = 64-49

EC = √15

2nd was with ΔAED:

AE² + 7² = 10²

AE² = 100-49

AE = √51

√51 + √15 ≈ 11

Answer:

9.4m is the answer.

Step-by-step explanation:

a = 8m

b = 5m

c = ?

According to the Pythagoras theorem,

a² + b² = c²

8² + 5² = c²

64 + 25 = c²

89 = c²

c = 9.433

Rounding off,

c = 9.4m

Answer:

The answer is "no".

Step-by-step explanation:

No, because the probability besides simultaneous flights to arrive on time are not self-sufficient for every flight (when the first flight was late, therefore the probabilities during the next flight were significantly greater), because then the standard multiplication principle would be used for explanatory variables.

Yes, we can multiply (0.85)(0.85)(0.85)(0.85)

Let the four flight be represented by A, B, C, and D respectively

Probability that each of the flights arrive on time is 0.85

That is:

Probability that flight A arrives on time, P(A) = 0.85

Probability that flight B arrives on time, P(B) = 0.85

Probability that flight C arrives on time, P(C) = 0.85

Probability that flight D arrives on time, P(D) = 0.85

Probability that the next four flights arrive on time will be:

P(A) x P(B) x P(C) x P(D) = 0.85 x 0.85 x 0.85 x 0.85

Yes, we can multiply (0.85)(0.85)(0.85)(0.85)

Answer:

your answer should be -2/3

Answer: See below

Step-by-step explanation:

Median is the value that separates the higher data and lower data. In simple terms, it is the "middle" value of the whole set of data. There are two different ways to solve for the median.

1. If the data set has an odd number of values, line the values up in increasing order. Then the value or number that lies in the middle will be the median.

2. If the data set has an even number of values, line the values up in increasing order. Then there will be two number that lies in the "middle" together. We add them up and divide them by 2. The average of the two numbers will be the median of the set.

Answer:

15%

Step-by-step explanation:

not that hard just make it a decimal then at the point go back twice and there its 15%

Answer:

15%

Step-by-step explanation:

Since 100 isn't the denominator we need to make it a denominator.

3/20 x 1/5 = 3/100 we need to do the same to the denominator because whatever we do to the denominator has to do with the numerator 3 x 5 = 15,

15/100 means 15%!
