I think you are asking what base 7 exponent would equal 49...
7^2 = 49
Step-by-step explanation:
we know that on a 30 60 90 trianlge the length of the side opposite the 30 degree angle is half of the length of hypotenuse.So in this problem
the length of the side opposite the 30 angle is 17/2
talking about exercise on the photo the answer is
8√3 because it is given that the length of the side opposite the 30 anlge is 8 so hypotenuse is 16 we mentioned why before.
Now lets use pythagorean theorem
x^2+y^2=z^2
z is hypotenuse
8^2+y^2=16^2
64+y^2=256
y^2=256-64
y^2=192
y=8√3
Answer: 19.2 miles is 30.72 km
Step-by-step explanation:
Since 5 miles is 8 km, divide 8/5 to find out how many miles is one kilometer.
8/5 = 1.6
Multiply 19.2*1.6 to find out how many kilometers 19.2 miles is.
19.2*1.6 = 30.72
(Note that when you search it up online, 19.2 miles is actually 30.9 km, because 5 miles isn't exactly 8km!)
12ft = 4 posts
4 x 4
=16 - 4
= 12
There is 4 post on each side but there is an overlap so you must take off 4 so there is no overlap
Therefore there are 12 posts
If the restaurant uses 150 grams and then sells 50 sub sandwiches
The ham needed is 50 x 150 = 7500 gram = 7.5 kg
