Answer:
s = sqrt(A - 25)/4
Step-by-step explanation:
A = 16s^2 + 25
Switch sides.
16s^2 + 25 = A
Subtract 25 from both sides.
16s^2 = A - 25
Divide both sides by 16
s^2 = (A - 25)/16
Take the square root of each side.
s = sqrt[(A - 25)/16]
s = sqrt(A - 25)/4
Answer:
y = 1.2x + 770
Step-by-step explanation:
y = m*x + b
Equation One
y = mx + b
1370 = m*500 + b
Equation Two
y = mx + b
1730 = m*800 + b
Solution
1730 = 800*m + b
1370 = 500*m + b Subtract. The b's cancel
360 = 300 * m Divide both sides by 300
360/300 = m
1.2 = m
Now use the second equation to solve for b
y = 1730
x = 800
1730 = 1.2*800 + b
1730 = 960 + b Subtract 960 from both sides
b = 770
okay so you did 1-5
Ima do 6-10
(if you didn’t do 1-5) just comment
6)
1/12+1/x=1/6
Multiply all terms by x
you’d get
1x/12+1=1x/6
Now solve that
You’d get 12
7)
1/12+1/x=2
Multipyl each term by x
1x/12+1 = 1x/2
Solve
you’d get
x=2.4
8)
1/8+1/x=1/4
Multiply x
1x/8+1=1x/4
Now solve
x=8
9)
1/10+1/11=1/x
Add 1/10+1/11 and get 21/110=1/x
Solve in proportion
get 5.24
10)
1/6+1/x=1/5
Multiply each by x
1x/6+1=1x/5
Solve
get 30
You’d get 110.21
Its 28214 grams. There are 1000 kilograms in a gram so you do 27 x 1000=27000g
Then you add 27000+547+694= 28214
