Answer:

88.2

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relevant relation ...

Tan = Opposite/Adjacent

tan(10°) = x/500

x = 500·tan(10°)

x ≈ 88.2 . . . . units

_____

If you move the "500" dimension to the top of the figure, you see it is adjacent to the given angle, and the value x is opposite.

Alona [7]

Answer: B

Step-by-step explanation: To obtain the mean for a general set of data, the formula used is;

= (sum of all the data set)/ (number of data set)

The number of data set for the two samples is 10

For the mean for the security company;

= (1.6+1.8+1.6+1.8+1.7+1.2+1.1+1.2+1.2+1.5)/10 = 14.7/10

= $ 1.47million

For the mean for the other companies;

= (1.5+2.1+1.9+2.2+1.9+1.7+2.1+2.2+2.2+1.8)/10 =19.6/10

= $ 1.96 million

The data from the samples have to be rearranged before the median can be obtained;

For the Security Company;

1.1 1.2 1.2 1.2 1.5 1.6 1.6 1.7 1.8 1.8

There are two data sets in the middle, therefore the median will be obtained by finding the average of the data sets;

= (1.5+1.6)/2 =$ 1.55 million

For the other companies;

1.5 1.7 1.8 1.9 1.9 2.1 2.1 2.2 2.2 2.2

There are two data sets in the middle, therefore the median will be obtained by finding the average of the data sets;

= (1.9+2.1)/2 = $ 2.00 million

Therefore, the answer is B

Answer:Simplificando

5 (2j + 3 + j) = 0

Reordene os termos:

5 (3 + 2j + j) = 0

Combine termos semelhantes: 2j + j = 3j

5 (3 + 3j) = 0

(3 * 5 + 3j * 5) = 0

(15 + 15j) = 0

Resolvendo

15 + 15j = 0

a verdadeira questão é por que o vizinho de Sarah quer dentes de tubarão

Step-by-step explanation:

Mova todos os termos contendo j para a esquerda, todos os outros termos para a direita.

Adicione '-15' a cada lado da equação.

15 + -15 + 15j = 0 + -15

Combine termos semelhantes: 15 + -15 = 0

0 + 15j = 0 + -15

15j = 0 + -15

Combine termos semelhantes: 0 + -15 = -15

15j = -15

Divida cada lado por '15'.

j = -1

Simplificando

j = -1

A physical education teacher plans to divide the seventh graders at Wilson Middle School into teams of equal size of year-ending

Crank

Step-by-step explanation:

Consider the provided information.

The total number of students are: 24+26+21=71

He wants each team will have the same number of students between 5 and 9.

The number between 5 to 9 are 6, 7 and 8.

The number 71 is a prime number so we need to divide the 71 students in group so that minimum students left without team.

Dividing 6 students in each group.

Number of teams: $\frac{71}{6}$ = 11 teams and 5 students.

Dividing 7 students in each group.

Number of teams: $\frac{71}{7}$ = 10 teams and 1 students.

Dividing 8 students in each group.

Number of teams: $\frac{71}{8}$ = 8 teams and 7 students.

Thus, we can not divide 71 students into equal teams, but 70 divided by 7 gives the least students left out i.e 10 teams each with 7 students and only 1 student will remain at last.
