Answer:
<u>60+14.35=88.27</u>
Step-by-step explanation:
5x12 for the rectangle on the right, then for the circle, using the formula A=πr², I get 28.27, which you divide by 2 because you only need half of the circle, and you get 88.27. I calculated the radius by subtracting 12-6 and then dividing that in half because the radius is half of the distance to the other end of the circle. Then you get the radius of 3, then plug it into the formula to get π(3)², which is just 3.14(9), and you get 28.27.
Volume of a cube = s³
Therefore, s³ = 512, meaning that s = 8.
The question asks what the resulting volume would be if all sides of the cube were divided by 4.
The current side measures 8, and we know that 8/4 = 2.
Thus, the resulting volume = s³ = 2³ = 8 cubic mm.
Pretty sure the mean is 5
Answer:
I use equal signs throughout but they are meant to be less than or equal to signs.
s=sandwiches
4.5s+6 less than or equal to 50
The answer is s is less than or equal to 12
Step-by-step explanation:
Finding Inequality
1. we know everything costs 50 in total so that is on one side of the equal sign.
____=50
2. we know he already spent 6 dollars so the money he can spend is 6 dollars less.
____+6=50
3. Each sandwich costs 4.50 $ so how much money does he have left to spend? we figure that out by multiplying the price by the number of sandwiches.
4.5s+6=50
Solving
1. 4.5s-6=50
First use the addition property of equality and add 6 to both sides.
2. 4.5s=56
Then use the division property of equality and divide each side by 4.5
3. you get a decimal but since you can't buy half a sandwich the answer is
s is less than or equal to 12
Answer:
Step-by-step explanation:
Using the exponential growth function for the U. S. population from 1970 through 2003:
A = 205.1e^0.011t
with the U.S. population being 205.1 million in 1970, when would the U. S. population reach 350 million?
A.
2028
B.
2048
C.
2018
D.
2038
We have the expression
A = 205.1e^0.011t
We are asked to find when would the U. S. population reach 350 million
A = 350
350 = 205.1e^0.011t
We divide both sides by 205.1
Divide both sides by 205.1
350/205.1 = 205.1e^0.011t/205.1
1.7064846416 = e^0.011t
We take the log of both sides
log 1.7064846416 = log e^0.011t
log 1.7064846416 = t log 0.011
t = log 1.7064846416/ log 0.011
t = 0.1185057826
