Answer 2

Answer:

B. Angle 2 and Angle 7 are alternate interior angles.

Step-by-step explanation:

Angle 2 and Angle 7 are actually alternate exterior angles. They are on opposite sides of the transversal and so the "alternate" part is correct, however, alternate interior angles are ones on the inside of the transversal, like angles 4 and 5.

Answers

Answer:

m∡A = 59°

m∡B = 48°

m∡C = 73°

Step-by-step explanation:

'x' = measure ∡A

73 + x - 11 + x = 180

2x + 62 = 180

2x = 118

x = 59

You want to send a package . First class mail costs $.39 for the first ounce and $.24 for each additional ounce . You can spend at most $ 3.00 on postage . What is the maximum weight of your package ? Round down to the nearest ounce .

Answers

Answer: 10 ounces

Step-by-step explanation: Ounce is equal to O and price is y

y=mx+b : y=.24o+.39

y = 3.00

3.00-.39=2.61

2.61/.24 = 10.875

round it down and you get the maximum

A shape is made of 9 right triangles of equal size and three identical rectangles.
Each rectangle measures 7 mm wide by 3 mm high. The rectangles are each
7 mm wide by 3 mm high. What is the total area, in square millimeters,
of the shape?

Answers

Answer:

The area of the figure is 157.5 square millimeters.

Step-by-step explanation:

Since a shape is made of 9 right triangles of equal size and three identical rectangles, and each rectangle measures 7 mm wide by 3 mm high, while the rectangles are each 7 mm wide by 3 mm high, to determine what is the total area, in square millimeters, of the shape, the following calculations must be performed:

Area of a rectangle: base x height

Area of a triangle: (base x height) / 2

7x3 = 21 = Rectangle area

7x3 / 2 = 10.5 = Triangle area

21 x 3 + 10.5 x 9 = 157.5

Thus, the area of the figure is 157.5 square millimeters.

Answers

Answer:

192,000,000

Step-by-step explanation:

Given

General form of an Exponential distribution :

y = ab^x

a = initial amount = 3000000

b = growth factor = 2

x = period = 24 / 4 = 6

y = final amount ; after one day = 24 hours ; x = 24 /4 = 6

y = 3000000(2)^6

y = 3000000 * 64

y = 192,000,000

Find an
explicit formula for the arithmetic sequence 37, 74, 111, 148, ....
Note: the first term should be a(1).

Answers

Answer:

Step-by-step explanation:

a₁ = 37

a₂ = 74

Common difference d = a₂ - a₁ = 37

nth term = a₁ + (n-1)d

= 37 + (n-1)37

= 37n

Answer:

Below in bold.

Step-by-step explanation:

The common difference is 74-37 = 37.

nth term a(n) = a1 + (n - 1)d

= 37 + 37(n - 1)

= 37n.

What is the equation for the translation of x2 + y2 = 81 six units to the left and five units up?

Answers

The formula would be (x + 6)^2 + (y - 5)^2 = 81.

This is the equation for a circle. We added plus 6 to the x term to get it to move to the left. And we add minus 5 to the y term to get it to move up 5 units.

Write an equation of the line that passes through the points (3,8) and (2.6). Write the equation in slope-intercept form.
The equation of the line in slope-intercept form is

Answers

Answer:

2x - y + 2 = 0 is the equation

y = 2x + 2 is the equation in slope-intercept form

Step-by-step explanation:

slope = (y₂ - y₁) / (x₂ - x₁)

slope = (6 - 8) / (2 - 3)

slope = -2 / -1

slope (m) = 2

equation through the points (3,8) and (2,6):

(y - y₁) / (y₂ - y₁) = (x - x₁) / (x₂ - x₁)

(y - 8) / (6 - 8) = (x - 3) / (2 - 3)

(y - 8) / -2 = (x - 3) / -1

-y + 8 = -2x + 6

2x - y + 2 = 0

slope-intercept form,

y = mx + c

y = 2x + 2
