Answer:
1st to 4th: Sam, Cras, Randy, Charte
Step-by-step explanation:
The places are determined by putting the times in increasing order.
<u>time</u>, <u>place</u>, <u>name</u>
25.85, 1st place, Sam
25.90, 2nd place, Cras
32.20, 3rd place, Randy
32.28, 4th place, Charte
_____
<em>Additional comment</em>
Sometimes it is easier to compare values when they all have the same number of decimal places.
Answer:
13
Step-by-step explanation:
39 divided by 3 = 13
52 divided by 4 = 13
65 divided by 5 = 13
so therefore, the constant of proportionality is 13
Answer:
175 means the city's population is 175 thousands in 2010.
Step-by-step explanation:
The model below gives the projection of the city's population , P, in thousands, with respect to time, t, in years, where 2010 corresponds to t=0.
The given equation is
We need to interpret 175 for the given model.
Substitute t=0 in the above equation.
At t=0 the value of P is 175 it means the city's population is 175 thousands in 2010.
Answer:
1548.66 feet
Step-by-step explanation:
We can draw a straight line down the middle to form two right triangles
This will split the 70 degree angle into two 35 degree angles
We now have two 90-35-55 right triangles
Now we can use cos(55) * the hypotenuse on both sides to get the distance across the lake
Thus we have:
1200cos(55 = 688.29
1500cos(55 = 860.36
Best of luck
240 ft^2 = L X W
240 = 3W x W
240 = 3W^2
W = 8.94427 ft
L = 3W = 3(8.94427)
L = 26.8328 FT
