Find, to the nearest degree, the angle of elevation of the sun at a time when a tree 20 feet high casts a shadow 12 feet long .
Answer:
Angle of elevation of sun = 59°
Step-by-step explanation:
Given:
Height of tree = 20 feet
Shadow of tree on ground = 12 feet
Find:
Angle of elevation of sun
Computation:
Height of tree = Perpendicular
Shadow of tree on ground = Base
Using trigonometry function;
Tanθ = Perpendicular / Base
Tanθ = 20 / 12
Tanθ = 1.66
Tanθ = Tan 59°
θ = 59°
So,
Angle of elevation of sun = 59°

Solve the following system of equations using substitution:
x − 2y = 14
x = -3y + 9
Answer:
X= 12
Y= -1
Step-by-step explanation:
Answer:
x=12, y=-1
Step-by-step explanation:
[x-2y=14, x=-3y+9]
[3y+9-2y=14]
simplify
[-5y+9=14]
isolate y for -5y+9=14: y=-1
For x=-3y+9, substitute y=-1
x=-3(-1)+9=12
x=12

Answer: 5
Step-by-step explanation:
You see 2x2 = 4 right and since this is operation 2 / 10 = 5 and 6-5 = 1 so add 1 and that gives you 5
2x2 = 4 / 10/2 = 5 / 6-5 = 1 +4 = 5
Answer:

Combine Like Terms:
[tex]=4x+6+−10
\\ =(4x)+(6+−10) \\ =4x+−4[/tex]
Which statements are true? Mark all that apply. A If y3 5 27, the value of y is 3. B If y3 5 64, the value of y is 4. C If y3 5 1, the value of y is 1. D If y3 5 16, the value of y is 2.
Answer:
A If y³ = 27, the value of y is 3. B If y³ = 64, the value of y is 4. C If y³ = 1, the value of y is 1
Step-by-step explanation:
Which statements are true? Mark all that apply. A If y³ = 27, the value of y is 3. B If y³ = 64, the value of y is 4. C If y³ = 1, the value of y is 1. D If y³ = 16, the value of y is 2.
Solution:
a) y³ = 27
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛27
y = 3
Option A is correct
b) y³ = 64
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛64
y = 4
Option B is correct
c) y³ = 1
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛1
y = 1
Option C is correct
d) y³ = 16
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛16
y = 2.52
Option D is wrong

the volume of the square pyramid is ___ cubic meters
Answer:
6000 m^3
Step-by-step explanation:
The basic formula for the area of a pyramid is 1/3 * b * h
where b is the base and h is the height.
The base is a square, so, we can find the area by squaring the side:
30^2 = 900.
Now, we can plug the values we have into the formula from above:
1/3 * 900 * 20
6000 m^3

6. The equation c = 523, 430(1.193)t models United States copper production in pounds from 1987 – 1992. Which statement best interprets the coefficient and base of this equation?
A) The copper production in 1987 was 523, 430 pounds, and it had been increasing at a rate of 1.93% per year during that period.
B) The copper production in 1987 was 523,430 pounds, and it had been increasing at a rate of 19.3% per year during that period.
C) The copper production increased by a factor of 523,430x1.193 pounds per year during that period.
D) The copper production at the beginning of 1987 was at 1.193 pounds, and it had been increasing by a factor of 523,430 pounds per year during that period.
Answer:
c
Step-by-step explanation:
Statement best interprets the coefficient and base of this equation Copper production increased by a factor of 523,430x1.193 pounds per year during that period.
We have given that,
The equation c = 523, 430(1.193)
It models United States copper production in pounds from 1987 to 1992.
What are the pounds?
The pound or pound-mass is a unit of mass used in British imperial and the United States customary systems of measurement.
from the given, we have the slope is 430.
Therefore the correct option is,
Copper production increased by a factor of 523,430x1.193 pounds per year during that period.

11. Max is designing a hot tub for a local spa.
He wants the hot tub to have a diameter of 89 inches, What is
the approximate area required for the installation of the hot tub?
(Use 3.14 for pi.)
NO PDF PLZ
Answer:
Area required for circular hot tube = 6,218 inch² (Approx.)
Step-by-step explanation:
Given:
Diameter of circular hot tube = 89 inches
Value of π = 3.14
Find:
Area required for circular hot tube
Computation:
Radius of hot tube = Diameter / 2
Radius of hot tube = 89 / 2 inches
Area required for circular hot tube = Area of circle
Area of circle = πr²
Area required for circular hot tube = πr²
Area required for circular hot tube = (3.14)(89/2)²
Area required for circular hot tube = (3.14)(7921 / 4)
Area required for circular hot tube = (3.14)(1,980.25)
Area required for circular hot tube = 6,217.985
Area required for circular hot tube = 6,218 inch² (Approx.)

Answer:
do you mean 3.8765? cuz if you do its 4
Step-by-step explanation:
The rounded number to the nearest whole number is 4.
What is rounding off?Rounding off is estimation. Estimating the actual number to its nearby number is called rounding off.
Given is a decimal number 3.8765 we need to round off to the nearest whole number,
3.8765 =
You rounded to the nearest ones place. The 3 in the ones place rounds up to 4 because the digit to the right in the tenths place is 8.
When the digit to the right is 5 or greater we round away from 0.
Hence, 3.8765 was rounded up and away from zero to 4.
Hence, the rounded number to the nearest whole number is 4.
