1. SHADOWS George
in the middle of the day
George's shadow is 15 feet long, and
pole's shadow is 45 feet long
If George is 6 feet tall, how tall is the light pole ?
Answer:
Step-by-step explanation:
15 (poles hight) divided by 6 (mans hight) is 2.5, so you would devide 45 by 2.5, and you get 18
Two-fifths of your yard is covered with grass. This is equal to what decimal?
Answer: 0.4
Step-by-step explanation:
Two-fifths is 2/5
If you were to put this into a calculator, you would get 0.4.
If this were to come up in a non-calculator test, I would mentally multiply both the numerator and denominator by 2 to get 4/10, which you can then divide quickly to get 0.4. :)
Is natural numbers closed under addition example?
Yes, natural numbers are an example of closed under addition.
Natural numbers are closed under addition and also multiplication. The addition of two or more natural numbers results in always a natural number. while for the case of subtraction and division, natural numbers don't obey the closure property, which means dividing or subtracting two natural numbers might not give a natural number. for example, considering two numbers 5 and 7, when we add both of them the result we come up with is 12, which is also a natural number.

What is the maximum height of the projectile? 82 feet 190 feet 226 feet 250 feet.
The maximum height of the projectile will be 226 feet that is, as per question, the option c.
A quadratic equation , y = ax²+bx+c (equation 1)
given, axis of symmetry is
x = [tex]\frac{b}{2a}[/tex]
As per the question:
The path of the projectile is modeled using the equation :
h(t) = -16t²+48t+190 (equation 2)
h(t) = height after t time.
comparing equation 1 and equation 2, we get
a = -16 and b = 48
further, t = [tex]\frac{48}{2(-16)}[/tex]
= [tex]\frac{48}{32}[/tex]
= 1.5sec
Substituting the found value in equation 2, we get
h(1.5) = -16(1.5)²+48(1.5)+190
h(1.5) = -36+72+190
h(1.5) = 226ft.
Thus, the maximum height of the projectile at 1.5 sec is, 226 feet.
Note that the full question is:
A projectile with an initial velocity of 48 feet per second is launched from a building 190 feet tall. The path of the projectile is modeled using the equation h(t) = –16t2 + 48t + 190.
What is the maximum height of the projectile?
A. 82 feet
B. 190 feet
C. 226 feet
D. 250 feet

What is the length of AB?
By using the fact that all the triangles are equilateral, we will see that AB = 32 units.
What is the length of AB?Here we have a figure made of equilateral triangles. Remember that all the sides of an equilateral triangle have the same measure.
Now we can see that FE = 16, then with that we can conclude that each segment of two consecutive vertices also measures 16 unints.
Now, we can write AB as:
AB = AD + DB
And we know that:
AD = 16 units
DB = 16 units.
Then:
AB = 16 + 16 = 32 units

the product of "-1.8" and 3 more than a number as the same as 1 / 10 what is the number
The product of -1.8 and = -1.8 x ?
3 more than a number = 3 + n
The product of -1.8 and 3 more than a number = -1.8(3 + n)
Is the same as 1/10 = equals (equal sign) 1/10
Full Equation: -1.8(3 + n) = 1/10
Steps to solve:
1. Divide both sides by -1.8 (or - 9/5)
(3 + n) = 1/10 x -5/9
3 + n = -5/90
2. Subtract 3 from both sides
n = -5/90 - 270/90

What is a linear function?
Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx.A linear function has one independent variable and one dependent variable.Slope formula:
m = (y₂ - y₁) / (x₂ - x₁)
Taking first two points from the given table

The area is the volume a flat, two-dimensional item occupies in a plane. The space occupied by a three-dimensional object is referred to as its volume. Area is measured in square units. Volume is measured in cubic units.
The volume formula is what.
The basic formula for volume is length, breadth, and height, as opposed to length, width, and height for the area of a rectangular shape. The calculation is unaffected by how you refer to the various dimensions; for instance, you can use "depth" instead of "height."
Given that :
Cube 1 has volume = 343 cubic feet
Volume = [tex]a^{3}[/tex]

mary is going to rent a truck for one day. there are two companies she can choose from, and they have the following prices. company a charges an initial fee of and an additional cents for every mile driven. company b charges an initial fee of and an additional cents for every mile driven. for what mileages will company a charge less than company b? write your answer as an inequality, using for the number of miles driven.
Company A costs less for mileage than Company B, which can be represented by the inequality 0 ≤ m < 85 .
The parameters for the two companies are as follows:
For Company A, the initial cost is $55.
For Company B, the initial cost is $97.50.
The extra cost per mile is 20 cents.
Let us depict the overall fee for company A by C₁ and the total charge for company B by C₂, and we will obtain;
C₁ = 55 + 0.70 × m
C₂ = 97.50 + 0.20 × m
Where "m" stands for the amount of miles driven.
Therefore, the cost of Company A and Company B are the same or equal when have the following relation;
C₁ = C₂
Now we will solve the equation to find the value of m.
∴ 55 + 0.70 × m = 97.50 + 0.20 × m
0.70 × m - 0.20 × m = 97.50 - 55
0.5 × m = 42.5
m = 85
m = 85 miles is the number of miles driven for which both companies will charge the same amount.
As a result, given that Company A's initial fee is smaller than Company B's initial fee, we have;
As a result, Company A charges less than Company B for 0 miles m 85 miles.
Therefore the inequality to represent is given by: 0 ≤ m < 85

A. What is the vertical rise per step (in inches rounded to the nearest inch)
B. Find the number of steps needed to climb from road level to the 2nd floor
(a) There are 10 vertical rise per step.
(b) There are 58 steps needed to climb from road level to the 2nd floor.
What is angle of elevation?
The angle of elevation is the angle created between the line of sight and the horizontal. The angle created is an angle of elevation if the line of sight is upward from the horizontal line.
(a) First to find the vertical rise per step.
x = 13 x tan(37)
x = 9.80
x ≈ 10
Hence, there are 10 vertical rise per step.
(b) Now to find number of steps needed to climb from road level to the 2nd floor.
The total elevation = 24 + 24 = 48 feet
Vertical rise of each step = 10
To convert 48 feet into inches
⇒ 48 x 12 = 576 inches
So, the number of steps = 576 / 10 = 57.6 ≈ 58

Because there is no underlying causative relationship, the null hypothesis holds that any experimentally detected difference is merely the result of chance; therefore, the name "null."
We can create a z-test hypothesis by assuming that the amount of rain produced by thunderheads follows a distribution that is nearly normal:
