[tex]b = l\times w[/tex] to guarantee that both formulas are the same.
Step-by-step explanation:
Dimensionally speaking, the volume is the cube of length. By direct comparison, we find that [tex]l,w,h[/tex] have length units, whereas [tex]b[/tex] have area unit, that is, the square of length.
Hence, [tex]b = l\times w[/tex] to guarantee that both formulas are the same.

For positive acute angles A and B, it is know that tan A= 8/15 and sin B= 11/61. Find the value of cos (a+b) in simplest form
Answers
Answer:
812/1037
Step-by-step explanation:
To solve this, we have to use trigonometric identities.
Cos (A + B) is given as Cos A Cos B - Sin A Sin B. And from the question, we have that
Tan A = 8/15.
We know that in a triangle, the Tan angle is represented Opp/Adj and thus the Opp is 8, and the Adj is 15. Using Pythagoras, we have
hyp² = opp² + adj²
hyp² = 8² + 15²
hyp² = 64 + 225
hyp² = 289
hyp = √289 = 17
The identity of Cos is Adj/Hyp and that of Sin is Opp/Hyp.
Cos A = 15/17
Sin A = 8/17
Repeating the same process for B, we have
Sin B = 11/61
adj² = hyp² - opp²
adj² = 61² - 11²
adj² = 3721 - 121
adj² = 3600
adj = √3600 = 60
Cos B = 60/61
Now, using the earlier stated trigonometric identity, we have
cos (a + b) = CosA CosB - SinA SinB
cos (a + b) = 15/17 * 60/61 - 8/17 * 11/61
cos (a + b) = 900/1037 - 88/1037
cos (a + b) = 812/1037

no, 3.5
no, 5.1
yes, 9.6
yes, 5.4
Answers
Answer:
the common difference is 5.4 and yes, this is an arithmetic sequence
Step-by-step explanation:
Each new term is derived by adding 5.4 to the previous term:
2.1 + 5.4 = 7.5,
7.5 + 5.4 = 12.9,
and so on,
so the common difference is 5.4 and yes, this is an arithmetic sequence.

Answers
Answer:
1. 65 coins
2. 79 - (23 + 22 + 20) = n
Step-by-step explanation:
You can use the expression 23 + 22 + 20 to get the amount of coins that are not nickles. And for two? Try it yourself.

Eric has 240 coins in his collection. 11\20 of his coins are pennies. 4\20 of the coins are nickels. The rest f the coins are quarters. How many of the coins are quarters? Explain how you got your answer.
Answers
Answer:Number of coins that are quarters =60
Step-by-step explanation:
Total coins in possession of Eric=240
Number of coins that are pennies=11\20 x 240= 132
Number of coins that are nickels=4\20 x 240= 48
Since the rest are quarters,
Number of coins that are quarters =Total coins in possession of Eric -( Number of coins that are pennies+ Number of coins that are nickels)
=240-(132+48)
=240-180
=60

Map quadrilateral ABCD to quadrilateral A′B′C′D′ with a rotation of 180° about the origin followed by a translation 3 units left and 7 units up.
Answers
Answer:
See Explanation
Step-by-step explanation:
Given
Shape: Quadrilateral ABCD
Transformations:
180 degrees rotation
3 units left
7 units up
Required
Determine A′B′C′D
The coordinates of ABCD is not given; So, I will solve generally.
Assume the coordinates of ABCD is (x,y)
When (x,y) is rotated 180 degrees, the new point is: (-x, -y)
Solving further:
Translation 3 units left
When a point (x,y) is translated b units left, the new point is (x - b, y).
So:
[tex](-x, -y) ====> (-x - 3, -y)[/tex]
Translation 7 units up
When a point (x,y) is translated h units up, the new point is (x, y + b).
So:
[tex](-x - 3, -y) ====> (-x - 3, -y + 7)[/tex]
Assume that the coordinates of A in ABCD before translation is (2,6).
i.e. A = (2,6)
The image A' will be:
[tex]A' = (-2-3,-6+7)[/tex]
[tex]A' = (-5,1)[/tex]

The perimeter and the area of the composite figure are 29 centimeters and 49.5 square centimeters, respectively.
How to determine the perimeter and the area of the figure
In this problem we have the representation of a composite figure, the result of the combination of a rectangle and a triangle. The perimeter of the figure is the sum of the sides and the area of the composite figure is the result of suming the areas of the rectangle and triangle:
Rectangle
A = b · h
Triangle
A = 0.5 · b · h
Where:
b - Baseh - HeightA - AreaAnd the perimeter and the area of the composite figure are now computed:
Perimeter
p = 6 cm + 7 cm + 6.5 cm + 9.5 cm
p = 29 cm
Area
A = 0.5 · (6 cm) · (2.5 cm) + (6 cm) · (7 cm)
A = 7.5 cm² + 42 cm²
A = 49.5 cm²
