Answer:

3/7

Step-by-step explanation:

the slope of the line is

-1 -6/ 3-0 = -7/3

the slope of the perpendicular line is:

3/7

Answer:

Below in bold.

Step-by-step explanation:

If one angle is x then the other is x+40 degrees.

These angles sum to 180 as we have a parallelogram, so

x + x + 40 = 180

2x = 140

x = 70.

So the angles are 70 and 110

110 ,70,110,70 are the angles

Let's say that angle 1 is x

This means another angle will be x - 40

The sum of all 4 angles is 360

The sum of two angles 180

x + x - 40 = 180

2x = 220

x = 110

180 - 110 = 70 meaning that each side has an angle measuring 110 degrees and an angle measuring 70. And 110 - 70 = 40 like you mentioned

Answer:

There is a strong linear corralation

Step-by-step explanation:

Answer:

Strong liner correlation

Step-by-step explanation:

Answer:

It is safe

Step-by-step explanation:

Using trigonometry :

Cosθ = adjacent / hypotenus

Hypotenus = length of ladder = 12 feets

Adjacent = distance between ladder and wall = 3 feets

Cosθ = 3 /12

Cosθ = 0.25

θ = cos^-1(0.25)

θ = 75.522°

To be safe ladder must be between (70 - 85)°

Sijce ladder is at an elevation of 75.22° ; then it is safe.

Hello.

In order to simplify the given expression, we need to use the Distributive Property, which states

a(b+c)=ab+ac.

So let's simplify it! :)

Multiply 11 times b and -3:

Answer:

The slope is 2500

Step-by-step explanation:

Given

See attachment for scatter plot

Required

Determine the slope of the scatter plot

From the plot, we can pick the following 2 points:

[tex](x_1,y_1) = (9,55000)\\[/tex]

[tex](x_2,y_2) = (3,40000)[/tex]

The slope (m) is then calculated as:

[tex]m = \frac{\triangle y}{\triangle x}[/tex]

This gives:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{40000-55000}{3-9}[/tex]

[tex]m = \frac{-15000}{-6}[/tex]

[tex]m = \frac{15000}{6}[/tex]

[tex]m = 2500[/tex]

The slope is 2500

Answer:

Step-by-step explanation:

Circumference

C = 2*pi * r

pi = 3.14

r = d / 2

r = 8/2

r = 4 feet

C = 3.14 * 2 * 4

C = 18.84 feet.

Area

pi = 3.14

r = d/2

r = 8/2

r = 4

Area = 3.14 * 4^2

Area = 3.14 * 16

Area = 50.24 ft^2

Answer:

in right angled triangle MNO

relationship between base and hypotenuse is given by cos angle

cosx°=b/h

cosx°=OM/MN

x°=cos-1(26/99)=74.77=74.8°

Answer:

∠ M ≈ 74.8°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos M = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{OM}{MN}[/tex] = [tex]\frac{26}{99}[/tex] , then

∠ M = [tex]cos^{-1}[/tex] ([tex]\frac{26}{99}[/tex] ) ≈ 74.8° ( to the nearest tenth )

Answer:

k = -4

Step-by-step explanation:

Applying the Distributive Property of Multiplication, we get

-3k + 15 = 27, which simplifies to   -3k = 12.  Then k must be

k = -12/3, or k = -4

Answer:

Step-by-step explanation:

The account value is given by the compound interest formula:

  A = P(1 +r/12)^n

Principal P invested at annual rate r compounded monthly for n months.

__

Using your parameters, the account balance would be ...

  A = $3000(1 +0.016/12)^66 = $3275.77 . . . account balance

The interest is the difference between this balance and the original investment amount:

  interest = $3000 -3275.77 = $275.77 . . . interest

Answer:

cos A = 53.13

Step-by-step explanation:

cos = [tex]\frac{adajacent}{hypotenuse}[/tex]

cos A = [tex]\frac{12}{20}[/tex]

cos A = 0.60

cos-1 0.60 = A

53.13 = A

Answer:

Since it's passed down on the X chromosome, red-green color blindness is more common in men. This is because: Males have only 1 X chromosome, from their mother. If that X chromosome has the gene for red-green color blindness (instead of a normal X chromosome), they will have red-green color blindness.

Answer:

7 rides

Step-by-step explanation:

38 - 10 (entrance fee) = $28 to spend on rides

if it's $4 per ride, we can divide the remaining money ($28) by the cost of each ride ($4)

28 / 4 = 7

Therefore, she can ride 7 rides
