10) 1 gallon of water for every inch of the fish's body length.
a) 2 1/2 inches long fish needs 2 1/2 gallon of water.
b) tank: l = 7 inches ; w = 5 inches; h = 7 ; volume = 7in * 5in * 7in = 245 in³
c) no. her fish tank is not large enough for the fish.
volume of 1 gallon of water is 231 in³, water needed is 2 1/2 gallon, so 5/2 * 231 in³ = 577.50 in³ volume.
11) volume = 7in * 3.5in * 1.75 in = 42.875 in³
weight of the brick = 0.1 pound per cubic inch ⇒ 42.875 in³ * 0.1 lb = 4.2875 pounds
weight of the gold bar = 0.7 pound per cubic inch ⇒ 42.875 in³ * 0.7 lb = 30.0125 pounds
12) l = 55cm ; w = 40cm ; h = 30 cm
volume = 55cm * 40cm * 30cm = 66,000 cm³
Answer:
6.6 miles
Step-by-step explanation:
due to the construction with the 3 parallel lines, the two crossing lines create 2 similar triangles (same angles and all side lengths and all other lines are all determined by the same multiplication factor going from one triangle to the other).
so,
LM = KL × f
MP = HK × f
HL = LP × f
KL = LM × f
and so on.
and then, also
JL = LN × f
the other thing we know due to the construction (L will always be connected with the middle of HK and MP) : the triangles are isoceles triangle (2 equal sides). in fact, because HK = HL = 2 miles, and it is an isoceles triangle, we also know that KL = 2 miles too.
so, we have
KL = LM × f
2 = 6 × f
f = 2/6 = 1/3
and therefore
JL = LN × f
2.2 = LN × 1/3
LN = 2.2 / 1/3 = 2.2 × 3/1 = 2.2 × 3 = 6.6
so, LN is 6.6 miles long.
Answer:
X ≤ 6
Step-by-step explanation:
3x + 9 ≥ 5x - 3
3x + 9 ≥ 5x - 3
Collecting like terms we have;
3X - 5x ≥ -3 -9
-2x ≥ - 12
X ≤ -12/-2
X ≤ 6
