Answer:

r = 3.25

Step-by-step explanation:

Solve for r:

0.5 (r + 2.75) = 3

Multiply both sides of 0.5 (r + 2.75) = 3 by 2:

2×0.5 (r + 2.75) = 2×3

2×0.5 = 1:

1 (r + 2.75) = 2×3

2×3 = 6:

1 (r + 2.75) = 6

Multiply both sides of 1 (r + 2.75) = 6 by 1:

1×1 (r + 2.75) = 1×6

1×1 = 1^2:

1^2 (r + 2.75) = 1×6

1^2 = 1:

1 (r + 2.75) = 1×6

1×6 = 6:

r + 2.75 = 6

Subtract 2.75` from both sides:

r + (2.75 - 2.75) = 6 - 2.75

2.75 - 2.75 = 0:

r = 6 - 2.75

6 - 2.75 = 3.25:

Answer: r = 3.25

What is the approximate volume of the sphere

NISA [10]

Answer:

523.33 mm³

Step-by-step explanation:

The general formula for the volume of a sphere is:

V = $\frac{4}{3}\pi r^{3}$

The radius for the given sphere is 5mm, so plugging that value into the equation and using 3.14 for π:

V = $\frac{4}{3}(3.14)(5^{3})$

V ≈ 523.33 mm³

A company sells boxes of duck calls (d) for $35 and boxes of turkey calls (t) for $45. they make batches of duck calls that fill

SIZIF [17.4K]

Answer:

Option A is the correct choice.

Step-by-step explanation:

Let d be the number of boxes of duck calls and t be the number of boxes of turkey calls.

We have been given that a company sells boxes of duck calls for $35 and boxes of turkey calls (t) for $45, so the revenue earned from selling d boxes of duck and t boxes of turkey call will be 35d and 45t respectively.

Further, the company plan to make $300. We can represent this information as:

$35d+45t=300...(1)$

We are also told that they make batches of duck calls that fill 6 boxes and batches of turkey calls that fill 8 boxes. the company only has 42 boxes. We can represent this information as:

$6d+8t=42...(2)$

$6d=42-8t...(2)$

Therefore, our desired system of equation will be:

$35d+45t=300...(1)$

$6d=42-8t...(2)$
