Answer:
15.4 minutes :)
Step-by-step explanation:
We need to turn the percentage into a decimal first :)
27/100 = 0.27
Now we multiply it by 57 to see how much time has gone by!! :)
0.27 x 57 = 15.39
Now to finish, we round!
9> 5
So 3 becomes 4

Answer:
230.77 seconds or about 3.85 minutes (2 minutes 50.4 seconds)
Step-by-step explanation:
First I will convert the minutes into seconds to make this a little easier.
1:01.71 would just be 61.71 seconds
400/61.71 is her speed for the first race. (speed is distance/time)
That is approximately 6.5 meters per second
time is distance/speed
1500/6.5= 230.769...
I do not know what you need to round to, but Juliette would take 230.769 seconds to run the 1500 meter race.
Answer: $475
Step-by-Step Explanation:
Let cost of a Garden Table be ‘x’
Let cost of a Bench be ‘y’
Framing the Equations :-
=> x + y = 912 (Eq. 1)
x = y - 38
=> x - y = -38 (Eq. 2)
On Adding Eq. 1 and Eq. 2, we get :-
2x = 874
x = 874/2
=> x = 437
Therefore, x = 437
Substitute value of ‘x’ in Eq. 1 :-
x + y = 912
437 + y = 912
y = 912 - 437
=> y = 475
Therefore, y = 475
Hence,
Cost of Garden Table = $437
Cost of Bench = $475
Answer:
The lateral area is equal to
Step-by-step explanation:
In this problem the lateral area is equal to the area of one equilateral triangle multiplied by
To find the area of one equilateral triangle calculate the height
The area of the triangle is equal to
we have
Applying the Pythagoras theorem
The area of one triangle is equal to
so
The lateral area is equal to
