Answer:
1) 1.203
2) 1.291
Step-by-step explanation:
1 mL = 0.001 L
1202.57120 mL = <u>1.202</u>57120 L
round to 4 sig fig = 1.203
1g = 10dg
0.1290743 g = <u>1.290</u>743 dg
round to 4 sig fig = 1.291
9514 1404 393
Answer:
(b) y/6 = 7/5.25
Step-by-step explanation:
Clockwise from the obtuse angle, the side ratios are ...
<u>Fig I</u> : <u>Fig II</u>
4.2 : 3.15
y : 6
7 : 5.25
6 : x
4 : 3
__
A true proportion will have corresponding parts of these ratios in corresponding places. The only true proportion listed is ...
Answer:
x = -6, y = -2
Step-by-step explanation:
2x-7y = 2
3x + y = -20
We need to cancel out either x or y to solve the equation. I'll cancel out x first
3(2x-7y = 2)
-2(3x+y=-20)
___________
6x-21y = 6
-6x -2y = 40
____________
-23y = 46
y = -2
Plug the value for y in one of the 2 equations to solve for x
2x -7(-2) = 2
2x+14=2
2x = -12
x=-6
Answer:
k=38
Step-by-step explanation:
add 22 to itself to cancel it out and add it to the 16 as well and you will get k
