The area is 128 yards squared
Answer:
4.104
Step-by-step explanation:
Volume of any prism = Area of cross section x height.
so, volume = 0.6 x 1.9 x 3.6 = 4.104
Answer: 54 square yards
Step-by-step explanation:
Given: The area of the scale model of a playground is 6 square yards.
let l be the length and w be the width of the model of playground.
then .....(1)
The scale model is enlarged by a scale factor of 3 to create the actual playground.
Then length of playground = 3l
width of playground = 3w
Then the area of the playground=
By using (1), we get
The area of the playground=
9514 1404 393
Answer:
70° (number in the blank at the bottom)
Step-by-step explanation:
You need to know the meaning of "complement of an angle."
Complementary angles have a sum of 90°. So, the complement of 20° is the angle that makes the total 90°. It is 70°.
The line at the bottom of the figure tells you how to work the problem. It says "the cosine of an angle is the sine of its complement." If you put numbers in this statement, it tells you ...
the cosine of 20° is the sine of 70°
So, the answer to the question at the top of the page is ...
look up the value of sin(70°) in the table
4.00 ÷ 0.25 = 16
.70 ÷ 0.05 = 14
16 quarters + 14 nickels = 30 coins
