6.3
use the equation 4/3 *r^3 *pi for each, then find the difference
Answer:
x= -1
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
10.8 cm
Step-by-step explanation:
we know that
1) A square picture with side length 30 cm is scaled by 60% on a photocopier
Remember that
![60\%=60/100=0.60](https://tex.z-dn.net/?f=60%5C%25%3D60%2F100%3D0.60)
so
The length of the first copy of the picture is
![30(0.60)=18\ cm](https://tex.z-dn.net/?f=30%280.60%29%3D18%5C%20cm)
2) The copy is then scaled by 60% again
so
The length of the second copy of the picture is
![18(0.60)=10.8\ cm](https://tex.z-dn.net/?f=18%280.60%29%3D10.8%5C%20cm)
Answer:
Step-by-step explanation:
-0.05 you will multiply with reversal of -5/16
-0.05 x (-16/5)= 0.01x16=0.16
Answer:
The correct answer is A.
Step-by-step explanation:
We are given:
The measure of two complementary angles are in the ratio 1 : 5
We know that the sum of complementary angles is 90 degree
Let the first angle be x
Let the other angle be 5x
Thus the equation we get:
x+5x = 90 degree
6x=90 degree
Divide both sides by 6
6x/6= 90/6
x= 15 degree
Now put the value of x in 5x
5x = 5(15)
= 75 degree
Thus the correct option is 15 degree, 75 degree....
