Answer:

180

Step-by-step explanation:

First you do 3 feet or 36 inches and multiply that by 5 to get 180.

Answer:So to get a 6 when rolling a six-sided die, probability = 1 ÷ 6 = 0.167, or 16.7 percent chance. So to get two 6s when rolling two dice, probability = 1/6 × 1/6 = 1/36 = 1 ÷ 36 = 0.0278, or 2.78 percent.

Step-by-step explanation:

Answer:

C.72

Step-by-step explanation:

rolling a six-sided number cube(6) x flipping a coin(2) x  rolling a six-sided number cube again(6)= 72

6x6= 36

         36 x 2 = 72

6x2=12

12 x 6 = 72

Step-by-step explanation:

Slope of line passing through (x₁, y₁) and (x₂, y₂) = (y₂-y₁)/(x₂-x₁)

Slope of line passing through (9, 7) and (2, 9) = (9-7)/(2-9) = -2/7

Answer:

The slope is [tex] - \frac{2}{7} [/tex]

Step-by-step explanation:

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

☆We need to find the slope . So just plug in according to the slope formula!

[tex]m =  \frac{9 - 7}{2- 9} = \frac{ \: \: 2}{ - 7} = - \frac{2}{7} [/tex]

===========================================================

Explanation:

Since y varies directly with x, this means y = kx for some constant k.

Plug in y = 98 and x = 14 to solve for k

y = kx

98 = k*14

98/14 = k

7 = k

k = 7

Therefore, y = kx updates to y = 7x which is the equation we're after.

Answer:

y = 7x

Step-by-step explanation:

The general formula for direct variation is y = kx, where k is the constant of proportionality.  If y = 98 when x = 14, then k must be 98/14. or 7, and so

y = 7x is the desired direct variation equation.

Ingredients for 30 flapjacks:

margarine = 350g

sugar : 300g

syrup :250g

The first step to determine the amount of ingredients needed to make one flapjack.

Ingredients for one flapjack:

margarine = 140 / 12

sugar : 120 / 12

syrup : 100 / 12

oats : 240 / 12

Ingredients for 30 flapjacks:

margarine = (140 / 12) x 30 = 350g

sugar : (120 / 12 ) x 30  = 300g

syrup : (100 / 12) x 30 = 250g

oats : (240 / 12) x 30 = 600g

Step-by-step explanation:

A circle is defined as a figure in which all points are equidistant from the center, or C.  In order to determine how far points A and B are from the center, we must first find the difference in positioning from (2,5) to each point and then use Pythagorean Theorem to calculate the length of the hypotenuse.  Point A establishes that the radius of the circle must be 10 units, and Point Bis only about 8 units away.

Answer:

1. 150π sq.ft  2. 10π ft

Step-by-step explanation:

Equation: Area of a sector = [tex]\frac{x}{360}[/tex] × π[tex]r^{2}[/tex]

Where:

x = internal angle

r = radius of circle

Values from problem:

x = 60

r = 30

Plug values into equation:

Area of sector = [tex]\frac{60}{360}[/tex] × π[tex]30^{2}[/tex]

Simplify:

60 divided by 30 equals [tex]\frac{1}{6}[/tex] and 30 squared equals 900 so...

[tex]\frac{1}{6}[/tex] × 900π

900π divided by 6 equals 150π so...

[tex]\frac{900}{6}[/tex] × π = 150π

150π sq. ft

Equation: Arc length = [tex]\frac{x}{360}[/tex] × 2πr

Where:

x = internal angle

r = radius of circle

Values from Problem:

x = 60

r = 30

Plug values into equation:

Arc length = [tex]\frac{60}{360}[/tex] × 2π30

Simplify:

60 divided by 360 equals [tex]\frac{1}{6}[/tex], and 2π × 30 equals 60π so...

[tex]\frac{1}{6}[/tex] × 60π

60π divided by 6 is 10π

[tex]\frac{60}{6}[/tex]π = 10π
