Answer
Option D is correct.
Cos C = (2/7)
Explanation
In a right-angle triangle, the side opposite the right angle is the Hypotenuse, the side opposite the given angle that is non-right angle is the Opposite and the remaining side is the Adjacent.
A sketch of this right triangle will be
This sketch allows Sin D = (2/7)
To know the right answer, we need to find the last side of the triangle
The Pythagoras Theorem is used for right angled triangle, that is, triangles that have one of their angles equal to 90 degrees.
The side of the triangle that is directly opposite the right angle or 90 degrees is called the hypotenuse. It is normally the longest side of the right angle triangle.
The Pythagoras theorem thus states that the sum of the squares of each of the respective other sides of a right angled triangle is equal to the square of the hypotenuse. In mathematical terms, if the two other sides are a and b respectively,
a² + b² = (hyp)²
For this question,
a = 2
b = ?
hyp = 7
a² + b² = (hyp)²
2² + b² = 7²
4 + b² = 49
b² = 49 - 4
b² = 45
b = √45
So, we can evaluate each of these
Cos D = (√45)/7
Cos C = (2/7)

equation represents Sherrick's graph.
<u>Step-by-step explanation:</u>
Here, Let us have a graph of line
, which will be a straight line passing through origin . Now, rotate the graph by 180° and now new equation becomes
, which is a straight line passing through origin . Now, shift the graph 3 units downwards on y axis so the new and final equation becomes
which is a straight line passing through at x = -3 at x-axis & y = -3 at y-axis.
∴ Equation which represents Sherrick's graph is
.
Answer: No, as the total cost of the 3 shirts w/ sales tax is $45.36 and she only has $45.
Step-by-step explanation:
Start by finding the price of one shirt on sale.

This equals 3.6 which is how much will be deducted from the original price.
One shirt costs
when its 20% off.
This is equal to $14.40.
Since she wants to buy 3 of them we just multiply the $14.40 by 3.

This equals $43.2 but this is without a 5% sales tax which is normally added to the total end price.
To add a sales tax you take the sales tax percent plus 1 and multiply it to the $43.2.

This means the total price of Kayla's purchase will be $45.36.
This is over her $45 she has so she can not buy it.
For this case, the first thing you should know is the following conversion of units:
360 degrees = 2pi radians
Applying the conversion we have:
θ = 180 * (2pi / 360)
Rewriting we have:
θ = pi
Answer:
the angle to radians is:
θ = pi
Answer:
50,671,706,112
Step-by-step explanation:
0.15*(18327440*18432)=50,671,706,112
15%= .15
x*18,432 = 18327440*18432=337,811,374,080
337,811,374,080 * .15 = 50,671,706,112
OR
337,811,374,080 / 15 =50,671,706,112
