Answer:
Step-by-step explanation:
for this equation
d=st
we can represent s as d/t
we can represent t as d/s
and in real world we have a lot of this type of equations
some of them are,
d=m/v ( density = mass / volume )
C = m.c ( heat capacity = mass x specific heat )
Answer: x >= -7
(x is greater than or equal to negative seven)
Answer:
0
Step-by-step explanation:
Solution for cosx=-3/2 equation:
cos((3*pi)/5)*cos((3*pi)/20) = 0
(60*x^3)/(60*x^5) = 0
cos((3*pi)/5)*cos((3*pi)/20) = 0
cos((3*x)/5)*cos((3*x)/20) = 0
1.5/100 = 0
Answer:
l = 16 cm
Step-by-step explanation:
Let's set the width of the rectangle as "w" and the length of the rectangle as "w/2 + 9".
The perimeter of a rectangle is calculated by adding up the value of all of its side lengths. Therefore, we can find the perimeter using 2l + 2w = P.
We can substitute 60 for P and w/2 + 9 for l.
- 2(w/2 + 9) + 2w = 60
- 2w/2 + 18 + 2w = 60
- w + 18 + 2w = 60
- 3w + 18 = 60
- 3w = 42
- w = 14
Substitute w = 14 into the equation for length l.
- l = w/2 + 9
- l = 14/2 + 9
- l = 16
The length of the rectangle is 16 cm.
6% of 750,000....turn percent to a decimal, " of " means multiply
0.06 * 750,000 = 45,000 <==
