Answer:

We conclude that:

  • m∠y = 70.53°

Step-by-step explanation:

From the given right-angled triangle,

  • Hypotenuse is 15
  • The angle is ∠y
  • The adjacent to angle ∠y is 5

Using the trigonometric ratio,

cos y = adjacent / hypotenuse

substituting adjacent = 5, hypotenuse = 15

cos y = 5/15

cos y = 1/3

y = arc cos (1/3)

y = 70.53°

Therefore, we conclude that:

  • m∠y = 70.53°

Answer:

x = 20

Step-by-step explanation:

50 - 38 = 12

a^2 + b^2 = c^2

16^2 + 12^2 = x^2

256 + 144 = x^2

400 = x^2

x = \sqrt{400}

x = 20

A total of 399 tickets were sold for the school play. They were either adult tickets or student tickets. The number of students
weqwewe [10]

133 adult tickets were sold.

Step-by-step explanation:

Given,

Total tickets sold for school play = 399

Let,

x represent the number of children tickets sold.

y represent the number of adult tickets sold.

According to given statement;

x+y=399      Eqn 1

x = 2y           Eqn 2

Putting value of x from Eqn 2 in Eqn 1

2y+y=399\\3y=399

Dividing both sides by 3

\frac{3y}{3}=\frac{399}{3}\\y=133

133 adult tickets were sold.

The endpoints of GE are located at G(-6,-4) , and E(4,8). Using slope-intercept form, write the equation of GE.
IRINA_888 [86]

Answer:

The line would be y = 6/5x + 26/5

Step-by-step explanation:

To find the equation, we first need to find the slope. We can do this by using the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (8 - -4)/(4 - -6)

m = 12/10

m = 6/5

Now that we have the slope, we can use that and either point in point-slope form to get the equation.

y - y1 = m(x - x1)

y - 8 = 6/5(x - 4)

y - 8 = 6/5x - 24/5

y = 6/5x + 26/5

The basketball team is playing in the championship game and wants to take a bus filled with family and friends to cheer for the
sergij07 [2.7K]

Answer:

Maximum number of people is 35

Step-by-step explanation:

With a total of $160 you have to pay for the bus and all the people. The bus cost $90 so you subtract that from the 160 because you bought (or rented) the bus. Then you have $70 left to pay for everyone's tickets. If each ticket is $2 then you can buy 35 tickets in total because 70 divided by 2 = 35.
