Answer:

I believe 57

Step-by-step explanation:

7 trees per 3 hours

6 hours = 14 trees

plus the 2 hours which I'm assuming 5 to 4 trees

so you multiply 19 trees per day

19 x 3 = 57 if I'm wrong please correct me :)

Answer:

If you take 50 and multiply it by two, you get 100. But, in order to get the right number, you have to multiply 45 by two as well. 45 x 2 is 90. 90 out of 100 is 90 percent. So 90% is the answer

Step-by-step explanation:

Answer:

96% or .96

Step-by-step explanation:

48 divided nu 50 equals .96 which then equals to 96 percent.

Robert has scored:

88+92+83+79+87+x=(85*6)

429+x=510

x=510-429=81

he needs to score an 81

Answer:

y = x + 1

Step-by-step explanation:

I HOPE IM NOT TOO LATE BUT basically first u use the points to find the slope:

[tex]\frac{3+1}{2+2} = \frac{4}{4} = 1[/tex]

so far then, u have y = x + b  (there's an invisible 1 in front of the x)

next, substitute in the values from one set of coordinates to solve for b. I picked the second one bc positive numbers are easier:

y = x + b

3 = 2 + b

3 - 2 = b

1 = b

put this into your equation, and u get y = x + 1

hope this helps!

Answer:

4007400000

You move the decimal place to the right 9 places.

Step-by-step explanation:

The required distance around the earth (circumference) in standard form is 40,074,000,000.

A number system is described as a procedure of organizing to express digits. It is the mathematical notation for representing the numbers of a given set by using numbers or other characters in a uniform method. It delivers a special exhibit of every digit and defines the arithmetic structure.

Here,
The number 4.0074 x 10¹⁰ means 4.0074 multiplied by 10 to the power of 10. To convert this number to standard form, we simply need to move the decimal point 10 places to the right.

So the answer in standard form is:

40,074,000,000

Thus, the required distance around the earth (circumference) in standard form is 40,074,000,000.

Using the together rate, it is found that it would take each bear 9 hours to open the car door alone.

The together rate is the sum of each separate rate.

In this problem, the rates are as follows:

Hence:

[tex]\frac{1}{x} + \frac{1}{x + 9} = \frac{1}{6}[/tex]

[tex]\frac{x + 9 + x}{x(x + 9)} = \frac{1}{6}[/tex]

[tex]x^2 + 9x - 12x - 54 = 0[/tex]

[tex]x^2 - 3x - 54 = 0[/tex]

Quadratic equation with coefficients [tex]a = 1, b = -3, c = -54[/tex], hence:

[tex]\Delta = b^2 - 4ac = (-3)^2 - 4(1)(-54) = 225[/tex]

[tex]x_1 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{3 + \sqrt{225}}{2} = 9[/tex]

[tex]x_2 = \frac{-b - \sqrt{\Delta}}{2a} = \frac{3 - \sqrt{225}}{2} = -6[/tex]

It would take each bear 9 hours to open the car door alone.

Answer:

=√18 or 4.24264068712

Step-by-step explanation:

used the distance formula

The equation of the ellipse will be x² / 36 – y² / 32 = 1.

An ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called foci adds up to a constant. It is taken from the cone by cutting it at an angle.

This ellipse is centered at the origin.

Vertices: (0,-6) (0,6)

Foci: (0,-2) (0,2)

Then the equation of the ellipse will be  given as

x² / a² – y² / b² = 1

Let c be the distance between the origin to foci.

Then we have

c = 2

And the value of a will be

a = 6

Then the value of a² will be

a² = 6² = 36

The value of b is the distance from center to one of the Co-vertices. Then the value of b² will be

a² – b² = c²

36 – b² = 2²

        b² = 36 – 4

        b² = 32

Then the equation of the ellipse will be x² / 36 – y² / 32 = 1.
