A bag contains 10 green marbles and 4 yellow marbles. If two marbles are chosen at random, one at a time and without replacement
balu736 [363]
Total marbles = 10+4 = 14
prob of green marble = 10/14 = .71
Then if you are getting 2 green marbles you have to first take out 1 green marble so now there are 9 green marbles and 13 total green marbles
prob of 2nd green marble = 9/13 = .69

So you would then multiply the probabilities of the individual events to get the total probability:
.71 * .69 = .4899 therefore(with rounding):

The probability of getting two green marbles is 49%

Use the net as an aid to compute the surface area of the triangular prism. A) 108 cm2 B) 120 cm2 C) 132 cm2 D) 170 cm2
nadya68 [22]

Step-by-step explanation:

Since there is no diagram of the triangular prism that we are required to calculate it's surface area. We can just fix random dimensions in order to enable us understand what we are required to do.

Meanwhile, a triangular prism is a solid shape that possesses two parallel triangles or triangular faces and about three rectangles or rectangular faces.

Example 1:

Calculate the surface area of a triangular prism with side 8cm, base 6cm and height 7cm.

Formula for calculating the surface area of a triangular prism is;

ab + 3bh

Where a = side of the prism

b = base of one of the triangular faces

h = height not the triangular face/prism.

Here a = 8cm

b = 6cm

c = 7cm

Substituting properly;

(8 × 6) + 3(6 × 7)

= 48 + 126

= 174cm^2. The surface area of the triangular prism is 174cm^2.

Example 2.

A triangular prism with side 9cm, height 4cm and base 5cm will be wrapped with a sheet of wrapping foil. Calculate the surface area of this rectangular prism.

The formula for calculating the surface area of a triangular prism = ab + 3bh

Where a = side

b = base

h = height of prism

In this case, a = 9cm

b = 5cm

h = 4cm

Substituting appropriately, we will have:

(9 × 5) + 3(5 × 4)

45 + 60

= 105cm^2

So, the surface area of this triangular prism is 105cm^2

Find the principal which will yield simple interest of N55.60 for 1yr 6 months at the rate of 2%
Norma-Jean [14]

There should be a point the line is going through, (1,2).

We have given that,

N55.60 for 1yr 6 months at the rate of 2%

We have to determine the principal which will yield simple interest of N55.60 for 1yr 6 months at the rate of 2%.

<h3>What is the simple interest?</h3>

A = P (1 + rt)

A = final amount

P = initial principal balance

r = annual interest rate

t = time (in years)

x = inches

y = miles

per 1 inch = 2 miles

so on the graph, there should be a point the line is going through, (1,2).

How to solve this question? i have to have 3 solutions
Helen [10]

The picture is a bit blurry but what I saw was 8a^3+27=0

8a^3+27=0 first you move 27 to the right side of the equation

8a^3=-27 then you divide both sides by 8

a^3 = -27/8 then take the cubed root of both sides

a= -3/2

Hope that helps ;)
