Answer: 44 gallons
Step-by-step explanation:
Using proportion,
33 gallons = 3hours
X = 4hours
Cross multiply
3 × X = 33 × 4
3X = 132
Divide bothside by 3
3x/3 =132/3
X = 44
Therefore the helicopter uses 44gallons for 4 hours.
Answer:
depends on what B is,
Step-by-step explanation:
if you just want an equivalent equation. b^3-12b^2+b, but otherwise theres no way to answer without an inequality or equivalent equation without B
Answer:
1.you don't need to calculate 25²,7²,30² and 16² because you have a formula a²-b²=(a+b)(a-b)
OP²=MO²-MP²
OP²=25²-7²
OP²=(25+7)(25-7)
=32(8)
=256
OP=√256
OP=16 cm
NP²=NO²-OP²
NP²=30²-16²
=(30+16)(30-16)
=46(14)
=144
NP=√144
=12 cm
2.draw a straight line from the angle C and name that line with CE
CE=AD and AE=CD (because AECD is a rechtangular)
So EB=10-7 =3 cm
BC²=EC²+EB²
=4²+3²
=16+9
=25
BC=√25
=5 cm

Complete Question
The body of 154-pound person contains approximately 2 x 10^-1 milligrams of gold and 6 x 10^1 milligrams of aluminum.
Based on this information, the number of milligrams of aluminum in the body is how many times the number of milligrams of gold in the body?
Answer:
300 times
Step-by-step explanation:
From the above question, we are told:
The body of 154-pound person contains approximately 2 x 10^-1 milligrams of gold and 6 x 10^1 milligrams of aluminum.
We create a proportion
2 × 10^-1 mg of gold : 6 × 10^1 mg of aluminum
= 0.2 mg of gold : 60 mg of aluminum
Therefore, the number of milligrams of aluminum in the body is how many times the number of milligrams of gold in the body is calculated as:
60mg ÷ 0.2 mg
= 300
Therefore, the number of milligrams of aluminum in the body is 300 times the number of milligrams of gold in the body
