Step-by-step explanation:
Tangent = opposite/ adjacent
Answer:
x = 21/2
y = -19/2
Step-by-step explanation:
5x - 17 = 4y + 7x
5x - 7x - 4y = 17
-2x - 4y = 17
6x + 8y = - 13
-2x - 4y = 17 | ×2 |
6x + 8y = - 13 | ×1 |
-4x - 8y = 34
6x + 8y = - 13
___________+
2x = 21
x = 21/2
-2x - 4y = 17
-2(21/2) - 4y = 17
-21 - 4y = 17
-4y = 17 + 21
-4y = 38
y = -38/4
y = -19/2
Answer:
B, C, and D
Step-by-step explanation:
Hey there!
In order to find if the area of these shapes are 24, we need to first find the area
A. Triangle: Base of 8 feet, Height of 3 feet
Formula for area of triangle: Base x height x 1/2
8 x 3 x 1/2 --> 24 x 1/2 --> 12
Not an answer
B. Rectangle: Width of 4 feet, Length of 6 feet
Formula for area of rectangle: Length x width
4 x 6 --> 24
It is an answer
C. Parallelogram: Base of 12 feet, Height of 2 feet
Formula for area of Parallelogram: Base x height
12 x 2 --> 24
It is an answer
D. Triangle: Base of 6 feet, height of 8 feet
Formula for area of triangle: Base x height x 1/2
6 x 8 x 1/2 --> 48 x 1/2 --> 24
It is an answer
In conclusion, the statements that make this rule true are:
B, C, and D
The samples he chose may not be a representative sample because the number of students per foreign language class may not be the same. One class may have a very large number of students while another may have only a few. Taking equal number of students per class is not a representative sample.<span />
