Answer:
61.4°
Step-by-step explanation
Given
Length of the ramp = 23ft = hypotenuse
Base of the ramp = 11ft = Adjacent
Required
Angle of elevation x
Using the SOH CAH TOA identity
Cos theta =adj/hyp
Cos x = 11/23
Cos x = 0.4782
x = arccos0.4782
x = 61.42°
Hence the angle of elevation is 61.4°
Answer:
$175. The new carpet will cost $175.
Step-by-step explanation:
7 meters long
$25.00 PER square meter
7 x $25.00 = 175
Answer:
m=4
Step-by-step explanation:
-5m=-20
m= - 20/-5
m=4
$240
Since a square yard is 3ft x 3ft, a square yard is equal to 9 square feet. Dividing 180 square feet by 9 square feet, we find that the room is 20 square yards.
Since carpet is $12 per square yard, and we have 20 square yards to cover, by multiplying 20 by $12, we find that the room will cost $240 to cover.
Answer:
9 is a rational no. andbecause it is a rational no. it will never be a e-rational no. . And because it is a rstional no. it will always be a integers, whole no,natual no. . And it will also be a Real no. coz all the no. are real no. including e rstionals also..
Step-by-step explanation:
The figure given above will help you to understand more clearly...
Look at the figure and see..
The largest circle is named or mark as yhe Real No. which means it includes all the no. . Each and every no. in the universe is surely real no..
No on the right is the e-rational no.. it does not consist of any type of no. under itself..
On the left is the rational no. which is consist of Integers, whole and Natural no...
So evey Integers, whole and Natural no. is rational.
Similarly every Integer is whole and Natural no..
Similarly every whole no. is a Natual no.
Hope it will help you..!
