Answer: 233.53 seconds
Step-by-step explanation:
Since we aren't given any further information in the question, the best time for the race based on the information given will be the addition of the top speed for each leg. This will be:
= 56.81 + 59.22 + 57.39 + 60.11
= 233.53 seconds
Therefore, the best time for the race is 233.53 seconds.
cosec 45^0
= ______ .
Answer:
cosec45° = [tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the identity
cosec x = [tex]\frac{1}{sinx}[/tex] and the exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex]
Then
cosec45° = [tex]\frac{1}{\frac{1}{\sqrt{2} } }[/tex] = [tex]\sqrt{2}[/tex]

A person invested $3,600 in an account growing at a rate allowing the money to
double every 7 years. How much money would be in the account after 17 years, to the
nearest dollar?
Answer:
$14400
Step-by-step explanation:
3600*2=7200 after the first 7 years
7200*2= 14400 after the next 7 years
17-14=3 years left after the first 14 years
The money in the account 17 years, to the nearest dollar is $20571.43.
Given that, a person invested $3,600 in an account growing at a rate allowing the money to double every 7 years.
What is the simple interest?Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.
Here, principal =$3600, money after 7 years= 2×3600 =$7200 and time period =7 years
2nd term:
Principal =$7200, money after 7 years = 2×7200=14,400
Thus, 17-14=3 years
Now, money for 3 years = 3/7 ×14,400
= $6171.43
So, money in the account after 17 years is
= 14400+6171.43
= $20571.43
Hence, the money in the account 17 years, to the nearest dollar is $20571.43.

Solve for ppp. -5\left(p+\dfrac35\right) = -4−5(p+ 5 3 )=−4minus, 5, left parenthesis, p, plus, start fraction, 3, divided by, 5, end fraction, right parenthesis, equals, minus, 4
Answer:
p = 1
Step-by-step explanation:
4 - 5(p + 3/5) = -4
Find P
4 - 5(p + 3/5) = -4
4 - 5p -15/5 = -4
4 - 5p - 3 = -4
-5p + 1 = -4
-5p = -4 - 1
-5p = -5
p = -5/-5
p = 1
Check:
4 - 5(p + 3/5) = -4
4 - 5(1 + 3/5) = -4
4 - 5 - 15/5 = -4
4 - 5 - 3 = -4
4 - 8 = -4
-4 = -4

156 people said they spent the night in Wal-Mart the night before Black Friday to get the good deals! This number represented 39% of the total number of shoppers at Wal-Mart. How many shoppers were at Wal-Mart?
Answer: 400 Shoppers
Step-by-step explanation:
Given
156 people spent the night in Wal-mart
These 156 people represent 39% of total shoppers at Wal-mart
Suppose x is the total no of shoppers at Wal-mart
So, we can write
[tex]\Rightarrow 39\%\ \text{of}\ x=156\\\Rightarrow 0.39\times x=156\\\\\Rightarrow x=\dfrac{156}{0.39}=400\ \text{People}[/tex]

Answer:
30
Step-by-step explanation:
These are djacent angles ( two angles that have the same vertex, share a side, and do not overlap) The 2 angles form a linear pair The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
If one angle is 150 then the other angle must be 30

from the top of the tower the angle of depression of a bottom of a pillar on the same surface of height is 20 metre is 60 degree. if the angle of depression from the top of the pillar to the bottom of a tower is 22 degree. find the height of the tower.
Answer:
85.74 m.
Step-by-step explanation:
tan 22 = 20/x where x is the distance between the tower and the pillar.
x = 20 tan 22 = 49.50.
tan 60 = h/49.50 where h is height of the tower
h = 49.5 tan 60
= 85.74 m.
