Numerical expressions use numbers and algebraic expressions use variables.
Answer:
B
Step-by-step explanation:
Taking a look at the orientation of the image and post-image, you can see that the rotation done was clearly 90 degrees counterclockwise. It was also shifted down by 3 units, and moved to the left by 2 units, mat the correct answer is choice b. Hope this helps!
Answer:
the cost of one sweater is $40
Step-by-step explanation:
The computation of the cost of the one sweater is shown below;
Let us assume the sweater be x
And, the pant be y
Now the equations are
2x + y = $120 ..............(1)
x + 2y = $120................(2)
Now multiply by 2 in equation 1
4x + 2y = $240
x + 2y = $120
3x = $120
x = $40
Hence, the cost of one sweater is $40
Angle to the top of the building or base of the tower = 36 degrees
Angle to the top of the radio tower on the building = 46 degrees
Distance from the base at which the surveyor is standing = 67 meters
Let us assume the distance of the base of the tower from the surveyor = x1
Let us assume the distance of the top of the tower from the surveyor = x2
Then
tan(36) = x1/67
x1 = 67 tan(36)
and
tan(46) - x2/67
x2 = 67 tan(46)
Now
x2 - x1 = 67 tan(46) - 67 tan(36)
= 20.702
= 20.7 m
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the second option or option "b".
The following recurring decimal as a rational number are 1/2, 13/100 and 341 / 1000
<h3>What is rational number?</h3>
A rational number is a number that is expressed as the quotient or fraction of two integers, a numerator and a non-zero denominator such as;
3/4. where,
- Numerator = 3
- Denominator = 4
Therefore,
0.5
= 5/10
= 1/2
0.13
= 13/100
0.341
= 341 / 1000
