Descent = 10 feet
Time required = 2 1/2 minutes.
The rate of descent = (10 feet)/(2.5 mn) = 4 ft/min
In 6 minutes, the descent will be
(4 ft/min)*(6 min) = 24 ft
Answer:
(a) 4 feet/minute
(b) 24 feet
Answer:
C
Step-by-step explanation:
A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola and the line is called the directrix.
Yes it will occur because two tenths of a mile the second relay will exchange
Yes they will have enough
The total cost of the items was $298.20
We find this by taking the cost of 1 thing like the curtains, then we see how many were brought, which was 3. So we do the cost which is $24.50 and multiply that by 3 to get $73.50. And we keep doing this with the other items and add them up.
For number 9 you have to convert from fraction to precent, the way i do this is by multiplying my denominator by a variable to get 100.
in this instance my denominator is 5 so 5x=100 in this case we are multiplying by 20. so 1(20)=20. it is important to recognize that 1/5 is equal to 20/100. now that we have an equivilent fraction we can use the numerator to be our precent. so the answer is A.20%
for number 10 we use the same idea. we know that 20 percent of people are for the visiting team so the rest of the pie chart would mean 80 percent of people were for the home team. We take the total number of people which is 64,000 and multiply our 80 percent, so we move the decimal
64,000(.80)=51200
so the answer for 10 is D.51200
