Answer:

e = 6

Step-by-step explanation:

to solve for x alone you need it alone.

multiply by both sides to get x alone --> e/2 x 2 = 3x2

the two on one side crosses out leaving --> e = 3x2

Answer: 0.56

Step-by-step explanation:

Given: Probability that Avacia tree grow small = 0.2

⇒Probability that Avacia tree grow large = 1-0.2=0.8 [Total probability =1]

Probability that Birch tree grow small = 0.4

⇒ Probability that Birch tree grow large= 1-0.4 = 0.6

The probability that both trees will grow to the same size = P(Both large)+P(Both small)

= 0.2 x 0.4 + 0.8  x 0.6   [Events are independent]

= 0.08+0.48

=0.56

Hence, the probability that both trees will grow to the same size = 0.56

The solution to the given expression starts fraction, 3, divided by, 4, end fraction, left parenthesis, 2, cubed, plus, 4, squared, right parenthesis, equal to 18.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We can solve the given expression by simple multiplication,

Answer:

14 arcade games and 8 photobooths were purchased

Step-by-step explanation:

x will represent the number of arcade games

y will represent the number of photobooths

We know that 22 total machines were bought which means that x+y=22

We also know that the total was 53600 which means that 2000x+3200y=53600

We can use substitution to solve this

x+y=22

x-22= -y

-x+22=y

Then plug this in for y in the next equation

2000x+3200(-x+22)=53600

Solve this and get x=14

Then plug in x=14 into any equation (I will choose the x+y one because that's easiest to solve)

14+y=22

this means y=8

This means that 14 arcade games and 8 photobooths were purchased

Answer:

The area of a triangle is: A = 23.2 cm²

Step-by-step explanation:

Given

a = 10 cm

b = 9 cm

The angle ∠C = 31°

To determine

Area of the triangle

Using the formula to determine the area of the triangle

Area = 1/2bc sin C

substituting a = 10, b = 9, and m∠C = 31°

Area = 1/2 × 9 × 10 × sin 31°

Area = 1/2(90) sin 31°

Area = 45 × sin 31°

Area = 23.2 cm²

Therefore, the area of a triangle is: A = 23.2 cm²

Answer:

Perimeter of circular garden=500m

Area=19,894 sq m

Step-by-step explanation:

250x4=1000

1000/2=500m circle perimeter

Pi x Dia=Circumference

3.14159 x Dia=500m

Dia=159.16m

Rad=159.16/2=79.58m

Area=Pi x Rad^2=2.14159 x 79.58^2=19,894 m^2

Answer: The circumference of the circular garden is 500 meters.

The area is approximately 19891 square meters.

If you use a Rounded value of 80m for the radius, the Area works out to about 20106 square meters.

Step-by-step explanation:

The total length of the rope is 1000m. 4×250=1000

That is enough to fence the circular garden twice, so the "perimeter" of that garden-- the circumference-- is 500m

To find the area, first find the diameter:

500÷π = 159.15

Area of a circle is A=πr²

The radius is half the diameter.

79.57 so r² is about 6331.4

Multiply by π to get the area:

about 19890.6 m²

super easy to use a calculator

Step-by-step explanation:

Answer:

Option C

Step-by-step explanation:

21 and 1/3 is 64/3 as an improper fraction, and 3 and 1/4 as an improper fraction is 13/4.

So, 64/3 feet divided by 13/4 inches, is 6 and 22/39 feet/inch.

Answer:

3/4

Step-by-step explanation:

1/3 + 1/4 + 1/6=3/4 of a cup-total amount of ingredients in her trail mix.

Simplify the following:

1/3+1/4+1/6

Put 1/3+1/4+1/6 over the common denominator 12. 1/3+1/4+1/6  =  4/12+3/12+2/12:

4/12+3/12+2/12

4/12+3/12+2/12  =  (4+3+2)/12:

(4+3+2)/12

4+3+2 = 9:

9/12

The gcd of 9 and 12 is 3, so 9/12 = (3×3)/(3×4) = 3/3×3/4 = 3/4:

Answer:

1 1/3 minutes

Step-by-step explanation:

Gasoline is pumped at rate of 3 gallons per minute into a container that already has 4 gallons inside

From the above question, we are to calculate the time at which the gasoline is pumped into the container

Hence:

Time = Number of gallons/Rate

Number of gallons = 4

Rate = 3 gallons per minutes

Hence:

Time = 4 gallons/3 gallon per minutes

Time = 1 1/3 minutes

The time at which the gasoline is pumped into the container is 1 1/3 minutes
