Answer: x=80°
Explanation:
To find the exterior angle x we first need to find the last corner angle (a) of the triangle. The angles of triangles add up to 180° so we can use the formula: 25+55+a=180
Solving formula:
25+55+a=180
80+a=180
(Subtract 80 from both sides)
a=100°
Now that we know a=100 we can find the exterior angle. a+x=180 because the angles are on a straight line which equals 180°
a+x=180
100+x=180
(Subtract 100 from both sides)
x=80°

i) first you combine the like terms; 3x² and x², then 4x and -8x, then -7n and -1.
Then you would get 4x²-4x-8.
You then cannot simplify further. so your answer would be 4x²-4x-8.
The tank WILL overflow.
60*30*40= 72000cm^3
<em>The max volume the fish tank can hold: 72000cm^3</em>
amount of L * 1000= cm^3
70L * 1000= 70000cm^3
<em>There is already 70000cm^3 of water in the tank</em>
70000cm^3 + 3000cm^3 = 73000cm^3
The tank can only hold 72000cm^3 and the water and rocks are 73000cm^3, so the tank will overflow.
Answer:
0.7 cups
Step-by-step explanation:
5 gallons, use 3 1/2 cups = 3.5 cups of lemonade
so 1 gallon, use 3.5/5 = 0.7 cups of lemonade
