18.75
Step-by-step explanation:
Answer:
60°
Step-by-step explanation:
We'll begin by calculating EC. This can be obtained as follow:
Angle EAC = 39°
Hypothenus = EA = 3.7 m
Opposite = EC =?
Sine EAC = Opposite /Hypothenus
Sine 39 = EC / 3.7
Cross multiply
EC = 3.7 × Sine 39
EC = 2.3 m
Finally, we shall determine angle BEC. This can be obtained as follow:
Adjacent = EC = 2.3 m
Hypothenus = BC = 4.6 m
Angle BEC =?
Cos BEC = Adjacent / Hypothenus
Cos BEC = 2.3 / 4.6
Cos BEC = 0.5
Take the inverse of Cos
BEC = Cos¯¹ 0.5
BEC = 60°
Thus, angle BEC is 60°
Answer:
Volume of cylinder is 34833.21 ft³
Step-by-step explanation:
Given : A right circular cylinder having height
ft and diameter
times its height.
Given : diameter
times its height that is
diameter
times
that is
Diameter =
Diameter =
ft
Radius is half of diameter,
Radius =
ft

Substitute the values, we get,




Thus, volume of cylinder is 34833.21 ft³
Answer: circle 2 and 5
Step-by-step explanation:
The problem is asking which number can 428 by divided by evenly.
Step 1: 428 divided by 2 is 214 Since it was evenly divided, you circle 2. It is the same for 4.
Step2: Keeping dividing each of the numbers to see if 428 can by divided by the number. If the answer comes out as a decimal number than don’t circle.
I’ve attached my work below for #4
5) 8% is equivalent to 8 cents so each item was $1.08
Than you know he spent 16.20 so you divided
1.08/16.20 which equals 15
So he got 15 items
6) the moon is 250,000 miles away which is about driving around earth 10 times which would take 6 months (not sure about this one)
Hope this helps!
Have a nice day :)
