c 1.50
d 1.19

Answer:

25° and 65°

Step-by-step explanation:

1. 65°-25°= 40°

2. 90°-65°=25°

3. 90°-25°=65°

Therefore 25° and 65° fit the criteria, make sure to add the degrees symbol :)

Complementary angles have a sum of 90° thus measure of the first and the second angle is 25° and 65° respectively.

Angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.

Let's suppose the first angle is x while the second is y.

If two angles have a sum of 90° then they will be called as complementary angles since x and y are complementary.

x + y = 90

Now given that,

The measure of the first angle is 40° less than the measure of the second.

x = y - 40

x - y = -40

By adding both equations,

(x + y) + (x - y) = 90 + (-40)

2x = 50

x = 25

y = 90 - 25 = 65

Hence "The first and the second angle is 25° and 65° respectively".

Answer:

if c = 4, it is 1/4 of a

Step-by-step explanation:

if c = 4,

b = c + 4 = 4 + 4 = 8

b = 8

a = b + 12 = 8 + 12 = 20

20/4 = 5

if c = 4, it is 1/4 of a

The vast majority of Americans – 96% – now own a cellphone of some kind. The share of Americans that own smartphones is now 81%, up from just 35% in Pew Research Center’s first survey of smartphone ownership conducted in 2011. Along with mobile phones, Americans own a range of other information devices. Nearly three-quarters of U.S. adults now own desktop or laptop computers, while roughly half now own tablet computers and roughly half own e-reader devices.

Answer:

-2 or 3

Step-by-step explanation:

Step 1: Factor equation.

(x+2)(x−3)=0

Step 2: Set factors equal to 0.

x+2=0 or x−3=0

x=−2 or x=3

-2 and 3 are the solutions to the equation x² – x – 6 = 0

To determine the solutions of the equation x² – x – 6 = 0

x² - x - 6 = 0

x² - 3x + 2x - 6 = 0

x (x - 3) + 2(x + 3) = 0

(x + 2) (x + 3) = 0

(x + 2) = 0

x = - 2......(1)

(x + 3) = 0

x = - 3..........(2)

x = −2 or x = 3

Therefore, -2 and 3 are the solutions to the equation  x² – x – 6 = 0.

Answer:

D) |−8,000 − (−50)|

Step-by-step explanation:

When we are dealing with questions involving above or below sea level,

The formula for the Absolute value expression representing the distance = | Height above sea level -(Distance below sea level|

Height of Cameron above sea level = 8000ft = -8000

Distance of the whale below sea level = 50ft = -50

Hence, we have:

|−8,000 − (−50)|.

Answer:

Step-by-step explanation:

Activity 2:

c² - 6c - 40

Sum = -6

Product = -40

Factors= -10 , 4

c² - 6c -40 = c² - 10c - 4c - 10*4

                = c(c - 10) - 4(c - 10)

               = (c -10) (c -4)

e²  + 10e +16

Sum = 10

Product = 16

Factors= 2 , 8

e² + 10e + 16 = e² + 2e + 8e + 2*8

                      = e(e + 2) + 8(e + 2)

                     = (e + 2)(e +8)

h²  - 5h  - 24

Sum = -5

Product = -24

Factors = 3 , -8

h²  - 5h - 24 = h²  + 3h - 8h - 3*8

                     = h(h + 3) - 8(h + 3)

                    = (h +3)(h - 8)

3x²  - 5 x - 12

Sum = -5

Product = -12 * 3 = - 36

Factors = -9 , 4

3x²  - 5x - 12 = 3x²  - 9x + 4x - 4*3

                    = 3x(x - 3) + 4(x - 3)

                   =(x - 3) (3x + 4)

4x²  + 4 x  - 15

Sum = 4

Product = 4 * -15 = - 60

Factors = 10 , -6

4x²  + 4x - 15 = 4x²  + 10x - 6x - 3*5

                      =2x (2x + 5) - 3(2x +5)

Answer:

63

Step-by-step explanation:

Because the two labelled angles make up a line, we know their sum is 180.

So, add them and set them equal to 180:

2x + (x - 9) = 180

Combine like terms:

3x - 9 = 180

3x = 189

x = 63

Thus, the answer is 63.
