How to find the number of times larger the diameter of the trunk of the tree is when compared with the diameter of the trunk of a bushGiven data
diameter of the trunk of a bush is 7.62 × 10^-2 meter
diameter of the trunk of a tree is 3.81 × 10^–1 meter
To achieve the comparison we divide the diameter of the trunk of a tree with the diameter of the trunk of a bush, as follows:
= 3.81 × 10^–1 meter ÷ 7.62 × 10^-2 meter

Answer:
Rita: r - 5= 2c, or r - 5= 2(36), or r - 5 = 72
Cora: (r - 5)/2 = 36
Step-by-step explanation:
Rita had r apps (let r = Rita original apps)She deleted 5 of them so r-5 She now has twice the number of apps as Cora so r-5 = 2c (let c = Cora's total apps) Cora's total apps are 36 so Rita's equation is r-5= 2(36) which means Rita equation for her number of apps is r-5= 72. As for Cora her equation is c= 36 but in relation to Rita's number of apps it's (r-5)/2 = 36Mohammad leaves home walks 5 blocks to the library. he then walks 2 blocks toward home to meet up with his friend. together, he and his friend walk to the library together. how far did mohammad walk?
If Mohammad leaves home walks 5 blocks to the library and he then walks 2 blocks toward home to meet up with his friend and then together, he and his friend walk to the library together, then Mohammad walked for 9 blocks.
To calculate how far Mohammad walked we use addition.
Total blocks Mohammad walked = blocks to the library + blocks towards home to meet up with friend + blocks back to the library together
blocks to the library = 5
blocks towards the home to meet up with friend = 2
blocks back to the library together = 2 (As he walked 2 blocks towards home from the library, he will walk the same number of blocks again to reach the library)
Therefore,
total blocks Mohammad walked = 5 + 2 + 2
total blocks Mohammad walked = 9
Hence, the number of blocks Mohammad walked for is calculated to be 9.

Using substitution method, the solution of the given system of equations is (-3,0)
A system of equation can be solved using:
graphical methodsubstitution methodelimination methodThe given system of equations:
4y - 6 = 2x ............ (1)
y - 3x = 9 .............. (2)
We need to find the solution using substitution method.
In equation (2), add 3x to both sides:
y - 3x + 3x = 9 + 3x
y = 9 + 3x ........ (3)
Substitute y = 9 + 3x into equation (1):
4y - 6 = 2x
4.(9 + 3x) - 6 = 2x
36 + 12x - 6 = 2x
12x - 2x = 6 - 36
10x = -30
x = -3

For each rational function, find any points of discontinuity.
y=2x-1 / x²+4
In rational functions, the discontinuities are caused by the denominator terms. Since the denominator of a fraction is non-zero, any term multiplied by the denominator is also non-zero.
To find the discontinuities, we need to factor the polynomial below. Once we have the two binomials, we set each to 0. This way, you can find the value that produces 0 in the denominator.
If x = -2 then (x^2) + 4 is 0.
So, the discontinuities are shown as x = -2

5. A rock is thrown straight up from a 224-foot tall cliff. The height of the rock as a
function of time is given by the equation h(t) = -16t² + 80t+224. How many
seconds until the rock hits the ground?
By finding the positive root of the quadratic equation, we conclude that the rock will hit the ground 7 seconds after it is thrown.
How many seconds until the rock hits the ground?
We know that a rock is thrown from a cliff whose height is 224 ft. And the equation that models the height of the rock as is the quadratic equation:
h(t) = -16t² + 80t + 224
The rock will reach the ground when its height is equal to zero, so what we need to find is the positive root of the quadratic equation, so what we need to solve is:
-16t² + 80t + 224 = 0
Solving it we get:
t = (-80 ± √(80² - 4*(-16)*224)/(2*-16)
t = (-80 ± 144)/(-32)
The positive solution is:
t = (-80 - 144)/(-32) = 7
This means that the rock will hit the ground 7 seconds after it is thrown.

According to the question, every morning Sally takes same bus and she has to wait to arrive with the used method called as uniform distribution.
And the range of the interval is as: min = 0 and max = 10.
For the calculation of the uniform distribution, the height some be constant.
Now, using standard uniform distribution formula:
Mathematically, the function f(x) can be written as:
f(x) = 1/(b - a)
where, 'a' and 'b' are defined intervals. Here, a = 0; b = 10.
Now, to calculate the percentage form the area as a rectangular grid which means:
f(x) = 1/10(5.3 - 2.5) = 2.8/10 = 0.28 = 28 percent.
Now, to know the percentile using above data:
f(x) = 1/(b - a) = 7/10 = 0.7 = 70 percent.

A student walked 100 meters north, then 100 meters west. How many more meters did the student walk compared to their total displacement from their starting point?.
Using Pythagorean theorem, the student walked 53.58 meters more compared to the total displacement from the starting point.
If a student walks 100 meters north, then 100 meters west, then the path he travels resembles the sides of a right triangle (see attached photo).
Using Pythagorean theorem, we can solve for the total displacement from the starting point to the end point.
c^2 = a^2 + b^2
where c is the total displacement from the starting point to the end point
a is the distance he walks up north
b is the distance he walks to the west
c^2 = 100^2 + 100^2
c^2 = 10,000 + 10,000
c^2 = 20,000
c = 141.42 meters
Comparing the total distance the student walked and the total displacement from the starting point to the end point by subtraction.
100 meters + 100 meters - 141.42 meters = 53.58 meters

Solve the equation x²+10 x+40=5 by completing the square.
So we are provided with the equation,
x2 + 10x + 40 = 5
To simplify it, we will first reorder the terms,
40 + 10x + x2 = 5
Now we will solve the equation to find the value of the unknown variable that we declared here as x.
40 + 10x + x2 = 5
Solving for variable 'x.'
40 + -5 + 10x + x2 = 5 + -5
We will combine similar terms; the variables and the constants.
40 + -5 = 35
35 + 10x + x2 = 5 + -5
Combine the like terms again:
5 + -5 = 0
35 + 10x + x2 = 0
Adding -35 on both sides
35 + 10x + -35 + x2 = 0 + -35
35 + -35 + 10x + x2 = 0 + -35
35 + -35 = 0
0 + 10x + x2 = 0 + -35
10x + x2 = 0 + -35
0 + -35 = -35
10x + x2 = -35
The x term is 10x.
Take half its coefficient (5) to make it a perfect square.
Square it (25) and add it to both sides.
10x + 25 + x2 = -35 + 25
25 + 10x + x2 = -35 + 25
-35 + 25 = -10
25 + 10x + x2 = -10
Perfect square on the left side:
(x + 5) (x + 5) = -10
We can see that the Square root of the right side can’t be calculated.

The ratio of the volumes of the Spaceship Earth to a golf ball = 1926949795 : 1
We need to find the volumes of the Spaceship Earth and a golf ball.
Spaceship Earth
Radius, R = 165/2 ft = 82.5 ft
Volume of the Spaceship Earth = [tex]\frac{4\pi R^3}{3}[/tex] = (4 x 3.14 x 561515.625)/3

1 ft = 12 inches
So 0.75 inches = 0.75/12 = 0.0625 ft.
So radius, r = 0.0625 ft
Volume of a golf ball = [tex]\frac{4\pi r^3}{3}[/tex] = (4 x 3.14 x [tex]0.0625^3[/tex])/3
