You just have to take your multiplication table and then you can find what multiplication make 24
6x4=24
2x12=24
3x8=24
So 2 3 4 6 8 12 are all the multiples of 24
The volume of a prism is the product obtained when multiplying the area of its base to its height. If the two given solid figures have the same volume and the same height then, the areas of their bases are also equal. Thus, the answer is letter D.
Answer:
15 ft
Step-by-step explanation:
Pythagoras formula for a triangle with a 90 degree angle :
a^2 + b^2 = c^2
c is the side opposite of the 90 degree angle. exactly or situation here.
=> 9^2 + 12^2 = x^2
=> 81 + 144 = x^2 = 225
=> x = sqrt(225) = 15
Answer:
Step-by-step explanation:
We can let b and c represent the cost of a book and the cost of a CD, respectively. Then the purchases can be described by ...
3b +7c = 79
5b +2c = 35
Using Cramer's rule to find the solution, we have ...
b = (7(35)-2(79))/(7(5) -2(3)) = 87/29 = 3
c = (79(5)-35(3))/29 = 290/29 = 10
The cost of each book was $3; the cost of each CD was $10.
_____
Cramer's rule tells you the solution to ...
ax +by = c
dx +ey = g
is ...
x = (bg -ec)/(bd -ea)
y = (cd -ga)/(bd -ea) . . . . same denominator
This solution is fully equivalent to using elimination or substitution to solve the problem. Using these formulas effectively "cuts to the chase" without all the intermediate steps. The cross-multiplying pattern of differences is not hard to memorize.
2pi radians=360 degrees
rato and proprtion
xrad/(2pi)=ydeg/360
xrad/2pi=82/360
times both sides by 2pi
xrad=164pi/360
xrad=41pi/90
aprox pi=3.141592
xrad=1.431
round
xrad=1.43 radians
1.43 radians=82 degrees
