Mathematics
1 answer:
jeyben [28]3 years ago

Answer:

Step-by-step explanation:

7). Since, ∠4 and ∠5 are the linear pair of angles,

    m∠4 + m∠5 = 180° [Supplementary angles]

    72° + m∠5 = 180°

    m∠5 = 180° - 72°

    m∠5 = 108°

8). Since, ∠6 and ∠7 are the vertically opposite angles,

    Therefore, ∠6 ≅ ∠7

    m∠6 = m∠7

    3x + 94 = 9x - 38

    9x - 3x = 94 + 38

    6x = 132

    x = 22

    m∠6 = 3(22) + 94 = 160°

    m∠7 = 9(22) - 38 = 160°

9). Since, ∠2 and ∠3 are the linear pair of angles, both the angles will be supplementary.

    m∠2 + m∠3 = 180°

    (13x + 54) + (2x + 36) = 180°

     15x + 90 = 180°

     15x = 90

     x = 6

     m∠2 = 13(6) + 54 = 132°

     m∠3 = 2(6) + 36 = 48°

The account executive of a brokerage firm has recommended that one of her customers consider stock from five aerospace companies
soldier1979 [14.2K]

Answer:

180 ways

Step-by-step explanation:

Aerospace companies (A) = 5

Energy development companies (D) = 3

Electronics companies (E) = 4

Number of aerospace stocks bought (a) = 2

Number of Energy development stocks bought (d) = 2

Number of Electronics stocks bought (e) = 2

The number of ways that the investor can select his six investments from the recommended list is given by the combination of picking two out five aerospace companies, multiplied by picking two out three energy development companies, multiplied by picking two out four electronics companies:

n=\frac{5!}{(5-2)!2!}*\frac{3!}{(3-2)!2!}*\frac{4!}{(4-2)!2!}\\  n=10*3*6\\n=180\ ways

There are 180 ways for the investor to select the six companies.

10.) A soccer team plays 104 tournaments in two
Gala2k [10]

Answer:

A. The Number of Lost games = 154 Games

B. Number of games won is greater than the number of games lost.

Step-by-step explanation:

A. how many games did they lose in both years?

Total Number of games = 104 tournaments x 3 Games in each tournament

Total Number of games = 312 Games

The No. of Lost games= Total Games in 2 years - Games won in 1st year - Games won in 2nd year

The No. of Lost games = 312 - 55 - 103

The No. of Lost games = 154 Games

B. Is the number of games won greater than the number of games lost?

Total Number of Games won = 158 Games

Total Number of Games lost = 154 Games

Hence, Total Number of Games won is greater than the Total Number of Games lost.

Which fractions are the same value as 16 divided by-3
iragen [17]

Answer:

Not sure if this was meant to be a multi choice question, but I'll try help anyway.

As long as you times the denominator and the numerator by the same number, many fractions can be of the same value as 16/-3.

For example, a potential answer to this could be 32/-6.

If we simplify this, we still get  16/-3.

They're different fractions, but of the same value.

Hope this helps!!
