Answer:

7/80

Step-by-step explanation:

(3 green, 4 yellow, 5 blue, 8 pink) = 20 marbles

P ( green or yellow  ) = number of green or yellow / total

                = (3+4)/20  = 7/20

Replace  

so we have (3 green, 4 yellow, 5 blue, 8 pink) = 20 marbles

P (blue) = number of blue/ total

                = 5/20  = 1/4

P ( green or yellow, replace, blue) = 7/20 * 1/4 = 7/80

A triangular pyramid has a base shaped like an equilateral triangle. The legs of the equilateral triangle are all 4 feet long, a
9966 [12]

Answer:

Total surface area of the pyramid =    25ft^{2}

Step-by-step explanation:

To find the surface area of the triangular- based pyramid, we will use the formula:

Surface area = Area of base + Area of the three faces

Area of base of the pyramid = Area of equilateral triangle = 0.5 \times base \times height

= 0.5 \times 4 \times 3.5= 7ft ^{2}

Area of the slant faces of the pyramid is 0.5 \times base \times slant height

0.5 \times 4 \times 3 = 6 ft^{2}

Since there are 3 slant surfaces the total surface area of the pyramid =7 + 3 \times (6)= 25ft^{2}

coffee is 7 times as old as his daughter in five years time he will be four times as old as his daughter what will be the ages I
ANEK [815]

Answer: CURRENT AGES: C = 35, D = 5 AGES IN 5 YEARS TIME: C = 40, D = 10

Step-by-step explanation:

We need to use algebra here.

Let C = Coffee's age

Let D = Daughter's age

C = 7 x D

C + 5 = 4 x (D + 5)

C + 5 = 20 + 4D

C = 15 + 4D

7D = 15 + 4D

D = 5

C = 7 x 5

C = 35

Inflation Rate Suppose the annual rate of inflation averages 2% over the next 10 years. With this rate of inflation, the approxi
alexandr1967 [171]

Answer:

After 10 years the cost will be $ 97.52.

Step-by-step explanation:

This problem requires us to calculate the cost of graphing after 10 years if inflation rate is two percent. This can easily be calculated by compounding present value of current cost at the rate of 2%. Detail calculation is given below.

FV= 80 (1+2%)^10

FV = $ 97.52

What is the slop-intercept of the line that passes through the points (7,-5) and (3,-9)?
bagirrra123 [75]

\bf (\stackrel{x_1}{7}~,~\stackrel{y_1}{-5})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{-9}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-9-(-5)}{3-7}\implies \cfrac{-9+5}{-4}\implies \cfrac{-4}{-4}\implies 1 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-5)=1(x-7) \\\\\\ y+5=x-7\implies y=x-12
