Answer:
372 miles
Step-by-step explanation:
The appropriate relation is ...
miles = (miles/gallon) × gallons
distance = (31 mi/gal)×(24 gal) = 744 mi
Brittany drove 744 miles to see the ocean. Since this was her round trip distance, the one-way distance is ...
744 mi/2 = 372 miles
If the whole diameter of sphere is 6 inch(means radius is 3 inch) & thickness of material is 1 inch, so the radius of the hollow part should be 2 inch (3-1=2)
The total volume of the ball will be;
= Total volume - Volume of hollow part
= 4/3πr³ - 4/3πr³
= 4/3 × 3.14 × (3)³ - 4/3×3.14×(2)³
= 4 × 3.14 × 9 - 4/3 × 3.14 × 8
= 113.04 - 33.52
= 79.52
If the density of the material is 3.25 g/in3, then the density of 79.52 inch³ should be;
= 79.52 × 3.25
= 258.44 g
Now, if there are 8 spheres in one box, the weight if box will be;
= 258.44 × 8
= 2,067.52 g

Answer:
6 1/2
Step-by-step explanation:
1 1/2 times 3 for 3 days = 4 1/2 + 2 = 6 1/2 So, the answer wold be 6 1/2 hours or 6.5 hours.
Answer:
0.336 in^2
Step-by-step explanation:
Scale down all the proportions:
14 × 0.10 = 1.4
8 × 0.10 = 0.8
3 × 0.10 = 0.3
Multiply new proportions:
1.4 × 0.8 × 0.3 = 0.336
Answer:
Both expressions are equivalent to 78 when t = 6 ⇒ answer A
Step-by-step explanation:
* To solve this problem substitute the value of t and then check
the answer
∵ The first expression is 2(7t - 3) ⇒ simplify it
# 2(7t) = 14t
# 2(3) = 6
∴ 2(7t - 3) = 14t - 6
- Substitute t by 4
∴ 14t - 6 = 14(4) - 6 = 56 - 6 = 50
- Substitute t by 6
∴ 14t - 6 = 14(6) - 6 = 84 - 6 = 78
∵ The second expression is 15t - 12
- Substitute t by 4
∴ 15t - 12 = 15(4) - 12 = 60 - 12 = 48
- Substitute t by 6
∴ 15t - 12 = 15(6) - 12 = 90 - 12 = 78
- The first expression has two values
# 50 when t = 4
# 78 when t = 6
- The second expression has two values
# 48 when t = 4
# 78 when t = 6
- From these information
# The two expressions have the same value 78 when t = 6
∴ Both expressions are equivalent to 78 when t = 6
