Answer:

8a-b+1

Step-by-step explanation:

Difference means subtract

(8a + 2b - 4) - (3b - 5)

Distribute the minus sign

(8a + 2b - 4) - 3b + 5

Combine like terms

8a + 2b-3b - 4  + 5

8a-b+1

Answer:

1. 523 cm^3

2. 1.6 ft

Step-by-step explanation:

1. Formula for volume of a sphere is (4/3)(pi)(r^3)

r = 5

(4/3)(3.14)(5^3) ≈ 523

2. Formula for volume of a cone is (1/3)(pi)(r^2)(h)

(1/3)(3.14)(1^2)(2) ≈ 2.0933

Plug this into the formula for volume of a sphere and find r.

2.093 = (4/3)(3.14)(r^3)

r ≈ 0.7937

Multiply by 2 to get the diameter, which is the height of the spherical barrier.

r * 2 ≈ 1.6

[tex]57\:\mathrm{km}[/tex]

Step-by-step explanation:

Since the question implies his truck travels at a constant distance per gallon, we can set up the following proportion to find how much father his truck can go.

Let [tex]x[/tex] represent how much farther his truck can go, in kilometers:

[tex]\frac{2}{76}=\frac{1.5}{x}[/tex]

Cross-multiplying, we get:

[tex]2x=76\cdot 1.5,\\x=\frac{76\cdot 1.5}{2}=\boxed{57\:\mathrm{km}}[/tex]

Answer:

Step-by-step explanation:

2 ÷ 76 = 1.5 ÷ d

2d = 76 × 1.5

d = 57 km

Answer:

m = .451

Step-by-step explanation:

3.3 + 10m = 7.81

Subtract 3.3 from each side

3.3-3.3 + 10m = 7.81-3.3

10 m =4.51

Divide each side by 10

10m/10 = 4.51/10

m = .451

Answer:

0.451

Step-by-step explanation:

3.3+10m=7.81

10m = 7.81-3.3

10m = 4.51

m = 4.51/10

m = 0.451

Answer:

N = 3/8 (Answer B)

Step-by-step explanation:

Here we need to isolate the variable N.  Rewriting 2 1/6 as the equivalent 13/6, we get:

13/16 ÷ N = 2 1/6 = 13/6.

Then 13/16 ÷ N = 13/6, or

(13/16)      13

---------- = ------

    N          6

Dividing both sides by 13, we get:

 (1/16)        1

---------- = ------

    N          6

Cross-multipying results in 6/16 = N.

Reducing this, we obtain the solution, N = 3/8 (Answer B)
