The answer is A.
Do you need an explanation?
387,500 /100 = 3,875
3,875 * 0.43 = 1,666.25
I multiplied, because, if you divide with a decimal, the number increases, instead of decreasing... hope this helps!
Answer:
535.9 ft²
Step-by-step explanation:
Since there are 360° in a circle, and 240° is 2/3 of 360°, we can say that the area of the bolded sector is <em>2/3 the area of the whole circle</em>. The area of a circle with a radius of r is πr², or approximately 3.14r², so the area of the whole circle is ≈ 3.14(16)² = 3.14(256) = 803.84 ft². Taking 2/3 of this gets us 803.84 * (2/3) ≈ 535.9 ft²
0.05n + 0.1d = 3.10
n + d = 44
d = 44 - n
Substituting to the first equation:
0.05n + 0.1(44 - n) = 3.10
0.05n + 4.4 - 0.1n = 3.10
-0.05n = 3.10 - 4.4
n = 26
Obtaining the value of nickels:
26 * 0.05 = 1.3
Therefore, the value of nickels that Bethany has is $1.30
We are given
Tobias dropped a tennis ball from a height of 60 meters. The time in seconds it takes for the ball to fall 60 feet is 0.25(radical60).
so, time is
we have to approximate it's value
First approximation set:
we know that
we can take sqrt all the sides
we can simplify it
Divide all sides by 4
Second approximation set:
Divide all sides by 4
Third approximation set:
Divide all sides by 4
so, we get
