Answer:
x = 72 degrees
Step-by-step explanation:
Use the definition of a tangent function:
tan x = opposite/adjacent
= 154/50
= 3.08
----> x = arctan 3.08 = 72 degrees
Answer:
7.5x+20 No
27.5+x No
20(7.5+x) Yes
150+x No
20x+150 Yes
Step-by-step explanation:
Answer:
<h2>475 inches</h2>
Step-by-step explanation:
You are right
Step one:
we are told that the total number of tiles is 100 in number
since each tile has a lenght of 4.75 inches each
a way to this is to add 4.75+4.75+4.75+...........................<em> in a hundred places to find the lenght.</em>
Step two:
Another way is to multiply 4.75 by 100 which is
=4.75*100= 475 in
<u>Hence the tile will cover 475 inches along the way</u>
Answer:
13
Step-by-step explanation:
Divide 12 by 3 first because of (PEMDAS) you get 4 tge add that to the 9 the you get 13.
P = parentheses
E = exponent
M = multiplication
D = division
A = addition
S = subtraction
Number of pencils x
number of pens y
3x + y = 10
x ≤ y
Draw the line 3x + y = 10 .[it passes by (0,10) and (-10/3,0)
Draw the line y=x [it passes by (0,0), (1,1), (2,2) etc]
Then the solution is the points with integer x and y, that belong to the segment of the line 3x +y = 10 between the x-axis and the line y=x. Those points are (1,7) , (2,4), (3, 1).
