Answer:
19 degrees
Step-by-step explanation:
Will have a triangle with horizontal distance being 2800, and vertical being 1000 feet. Angle between the horizontal and hypotenuse is what we are looking for.
Thus it's a tangent function.
SOH
CAH
TOA <-----
Tangent is the opposite / adjacent
So we will be looking at doing an Arctan to find the angle.
Arctan α = [tex]\frac{1000}{2800}[/tex] = 19.29 degrees. Round to the nearest whole degree would be 19 degrees due to being less than .50
Your answer is 19 degrees
Turn this improper fraction in mixed numbers.23/7
Answer:
3 2 /7
Step-by-step explanation:
Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.
What is the value of x in the equation -2/9x2/5 ?
A. -1 4/5
B. -5/9
C. 5/9
D. 1 4/5
Answer:
-1 4/5
Step-by-step explanation:
-2/9x = 2/5
(multiply both equations by 9 and 5)
So
-10x = 18
(divide both equations by -10)
x = - 18/10
Simplify:
x= - 9/5
= - 1 4/5

Choose 3 values that would make this inequality true. 7n ≤ 21
Answer:
A couple could be 2, 1, or even a decimal 1.3 as an example.
Step-by-step explanation:
Divide both sides by 7:
7n/7 < 21/7
n < 3
Any value of n less than 3 will make the inequality true, so just pick three values (numbers) for n that are less than 3, such as n = 2.

Identify in the given expressions, terms which are not constants. Give their numerical coefficients.
(i) 5x – 3
(ii) 11 – 2y2
(iii) 2x – 1
Given:
The expression are
(i) [tex]5x-3[/tex]
(ii) [tex]11-2y^2[/tex]
(iii) [tex]2x-1[/tex]
To find:
The terms which are not constants and their numerical coefficients.
Solution:
Constants: The terms which are free from variables.
Numerical coefficient: Number multiplied with a variable.
(i) [tex]5x-3[/tex]
Constant = -3
Term which is not constant = 5x
Numerical coefficient = 5
(ii) [tex]11-2y^2[/tex]
Constant = 11
Term which is not constant = [tex]-2y^2[/tex]
Numerical coefficient = -2
(iii) [tex]2x-1[/tex]
Constant = -1
Term which is not constant = 2x
Numerical coefficient = 2
Therefore, the terms which are not constants are [tex]5x,-2y^2,2x[/tex] respectively and their numerical coefficients are 5, -2, 2 respectively.
The length of a rectangle is 9” greater than the width. The area is 36”2. Find the dimensions
Answer:
Step-by-step explanation:
L = W+9
area = LW = 36
(W+9)W = 36
W²+9W-36 = 0
W = -12, 3
-12 is an extraneous solution, so W = 3 inches
L = W+9 = 12 inches
