Answer:

x=21°

Step-by-step explanation:

3x+x+96°=180°

4x=180°-96°

4x=84°

x=84°/4

x=21°

Answer:

x = 21 degrees!

Step-by-step explanation:

3x + x + 96 = 180

4x +96 = 180

Subtract 96 from both sides!

4x = 84

Divide by 4 from both sides!

x = 21 degrees

The average commute to work (one way) is 25 minutes according to the 2005 American Community Survey. If we assume that commuting
Stolb23 [73]

Answer:

1. 0.1635

2. 0.0026

Step-by-step explanation:

The computation of the probability in the following cases are as follows:

1.

Given that

Mean = 25 minutes

ANd, the standard deviation is 6.1 minutes

So here the z score would be

= (31 - 25) ÷(6.1)

= 0.98

Now the probability is

= P(Z>0.98)

= 0.1635

2. the z score would be

= (8 - 25) ÷(6.1)

= -2.79

Now the probability is

= P(Z<-2.79)

= 0.0026

The line through (4,-1) and (k,5) is parallel to the line y=-3x+5. FInd the value of k.
Tema [17]

Answer:

k = 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 5 ← is in slope- intercept form

with slope m = - 3

Parallel lines have equal slopes, thus the 2 points have a slope of - 3

calculate the slope using the slope formula and equate to - 3

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (4, - 1) and (x₂, y₂ ) = (k, 5)

m = \frac{5+1}{k-4} = \frac{6}{k-4} = - 3 ( multiply both sides by (k - 4) )

- 3(k - 4) = 6 ( divide both sides by - 3 )

k - 4 = - 2 ( add 4 to both sides )

k = 2

Mazyrski [523]
7.75 ➗ 125 = 0.062


Simplify ➡ 31 / 4


31 over 4 ➗ 125


Then, divide ➡31 over 1 by 125


and it should leave you with the answer 0.062

A leatherback sea turtles was swimming at 850 below sea level. He went 165 meters and then descendes 165 meters. Draw a number l
Step2247 [10]

Answer:

The answer is below

Step-by-step explanation:

a) Let negative means the turtle position when descending and positive for going up. Therefore since the turtle was 850 meters below see level, it was at -850. It then moves 165 meters up, hence its new position is -685 meters (-850 + 165). Lastly it moves down 165 meters, hence its new position is -850 meters (-685 - 165)

b) The change in position is the sum of the movements = +165 - 165 = 0 meters.
