A scout troop is planting trees at the state park. The troop planted 7 trees in 3 hours. At that rate, how many trees will they be able to plant in three 8-hour days?
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 :)

A tourist ignores the warning signs and leaves food in his car while he goes for a hike. A mama bear and her cub open the car door in six seconds. How long would it take each bear to open the car door alone if the cub needs 9 more seconds than the mama bear?
Answer:
0 sec. I help him get the tourist too :)
Step-by-step explanation:
jk, but her cub takes 13 and the mama 4
Using the together rate, it is found that it would take each bear 9 hours to open the car door alone.
What is the together rate?The together rate is the sum of each separate rate.
In this problem, the rates are as follows:
Together rate: 1/6.Mama's rate: 1/x.Cub's rate: 1/(x + 9).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:
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.
What is a number system?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.

Answer:
-3 and 1
Step-by-step explanation:
The zeros of the given function are -3 and 1.
What are zeros of a function?The zeros of a function, also referred to as roots or x-intercepts, are the x-values at which the value of the function is 0 (f (x) = 0). The zeros of a function can be thought of as the input values that result in an output of 0.
Given is a function f(x) = (x + 3)(x - 1)/(x-2)(x + 2),
We need to find the zeros of the function,
Equate to 0,
(x + 3)(x - 1)/(x-2)(x + 2) = 0
Therefore,
(x + 3)(x - 1) = 0
x+3 = 0 and x-1 = 0
Therefore,
x = -3, x = 1
Hence, the zeros of the given function are -3 and 1.

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!
