Answer: You can say that the slope is negative since the graph is decreasing.
Step-by-step explanation:
Take $969.50 and divide it by 7, for the week. You should end up with an answer of $138.50, if I did my math correctly.
Answer:
Step-by-step explanation:
A rectangle is a closed planer quadrilateral with four right angles and its opposite sides are the same length. The fence around it including the gates is 200 feet long, so basically they are providing the perimeter of the rectangle. The perimeter of a rectangle is equal to the sum of all its sides. Hence:
The ectangular playground is 40 feet wide, so:
Therefore:
Solving for h:
The area of a rectangle is equal to the product of two of its contiguous sides, hence:
I attached you a picture of the rectangle
Answer:
20.78460969 = s
Step-by-step explanation:
tan theta = opposite side / adjacent side
tan 60 = s /12
Multiply each side by 12
12 tan 60 = s /12 *12
20.78460969 = s
Answer:
Step-by-step explanation:
It is given that the quadrilateral ABCD has AB ≅ CD and BC ≅ DA is a parallelogram, then in order to prove opposite angles of the parallelogram are equal, we take ΔABC and ΔADC,
AC=AC(Common)
AB=CD(given)
BC=AD(given)
Thus, by SSS rule, ΔABC ≅ ΔADC
By CPCT, ∠B=∠C
Also, from ΔABD and ΔBCD, we have
AB=CD(given)
BC=AD(given)
BD=BD(common)
Thus, by SSS rule, ΔABD ≅ ΔBCD
By CPCT, ∠A=∠C
Since, opposite angles are equal,therefore ABCD is a parallelogram.
Draw in diagonals AC and BD. The given information and the shared side AC along with the Reflexive Property can be used to prove ΔABC ≅ ΔADC by the SSS Congruence Postulate. Using CPCTC, ∠B=∠C.The same can be done for ΔABD ≅ ΔBCD using the given information and the shared side BD. This will lead to ∠A=∠C. Therefore, ABCD is a parallelogram because opposite angles are congruent.
