Answer:
A
Step-by-step explanation:
Let's check each one-by-one.
a.
we know 3.79 liters is 1 gallon, so 4 liters IS NOT LESS THAN 1 gallon
THis is false.
b.
We know 1 feet is 0.30 meters, so definitely 1 foot is less than 1 meter.
This is true.
c.
we know around 28.35 grams is 1 ounce, so definitely 25 grams is less than 1 ounce.
THis is true.
d.
We know 1 km is approximately 0.62 miles so 10 km would be around 0.62*10 = 6.2 miles
So definitely 9 miles IS GREATER than 10 km.
THis is true.
So answer choice A is false, only.
For the 51-deg angle, y is the opposite leg, and 12 is the hypotenuse.
The trig ratio that relates the opposite leg and the hypotenuse is the sine.
sin A = opp/hyp
sin 51 deg = y/12
y = 12 * sin 51 deg
y = 9.3
Given:
The system of equations is
To find:
The graph of the given system of equations and its solution.
Solution:
The table of values for is
x y
-4 7
-2 2
0 -3
Plot these points and connect them by a straight line.
The table of values for is
x y
-4 0
-2 2
0 4
Plot these points and connect them by a straight line.
From the below graph it is clear that the lines intersect each other at point (-2,2).
Therefore, the solution of given system of equation is (-2,2).

Answer:
2 1/4 days
Step-by-step explanation:
You could extend your table a bit to help answer this.
(days, hours)
(1, 24)
(1/2, 12)
(1/4, 6)
(2, 48)
Now, we observe that 54 hours is 6 more hours than 48 hours, so will be 1/4 day more than 2 days.
54 hours is 2 1/4 days
