Answer:

Step-by-step explanation:

1. X + y

Putting values of x and y

-7 + (-3)

= - 10

2. xy

Putting values of x and y

(-7)(-3)

= 21

3. x2 + y2

Putting values of x and y

= (-7)2 + (-3)2

= 49 + 9

= 58

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

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

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

I double checked the math on desmos and it is correct

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: 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
