Answer:
The tap drains approximately half the water from the tank in 15 minutes
The tank initially has 50 gallons of water
Step-by-step explanation:
<u>The tap drains approximately half the water from the tank in 15 minutes. </u><u>True.</u>
This is true because see that the point (15,25) lies on the graph of the line.
Which means after 15 minutes the amount of water left in the tank is 25 gallons and 25 is half of 50.
The tap drains exactly one gallon from the tank every minute. False
This is false because the slope of the graph is 
<u>The tank initially has 30 gallons of water. </u><u>False.</u>
The y-intercept is the initial gallons of water which is 50.
<u>The tank initially has 50 gallons of water. </u><u>True.</u>
The y-intercept is the initial gallons of water which is 50.
<u>The tank takes 50 minutes to drain completely. </u><u>False</u><u>.</u>
It is false because the x-intercept tells us the tank is drained completely and it is not 50 minutes but rather 30 minutes.
Answer:
Set up an equation
-4+x=4 Add 4 to each side
x=8
So
-4 plus eight is 4
Answer:
-1
Step-by-step explanation:
g(-1) = -5/-1 = 5
g(5) = -5/5
g(g(-1)) = -1
i don't now all of them but
3.is "A"
4.is "C"
* By definition, the sum of the interior angles of a triangle is 180 degrees.
* Keeping this in mind, you have:
As you can see, the sum of the other two angles must be 108 degrees, then, let's add the angles given in each option:
A) 9°+9°=18
B) 26°+46°=72°
C)53°+55°=108°
D)72°+108°=180°
*Therefore, the answer is option C.
5.is "B"
A triangle is called a right triangle when one of it's angles measures 90°.
We have been given the second angle as 14°.
The angles in a triangle add up to 180°.
∴ letting the third angle to be X;
X + 14° + 90° = 180°
X + 104° = 180°
X = 180° - 104°
= 76°
7. the answer is "B"
A = 41 * 14 / 2
A = 574 / 2
A = 287 cm²
So, the area of the trapezoid is 287 cm².
9. is "B"
Area = base x height
Or 356.25=14.25 x Height
Dividing both sides by 14.25
Height =25inches
.Height of the parallelogram is 25 inches. the answer is "B"
10.is "B"
the sum of any 2 sides of a triangle must be greater than the third side
