Mathematics
1 answer:
Naddika [18.5K]4 years ago
3 0

Answer:

x ≤ a → x ∈ (-∞, a]

x < a → x ∈ (-∞, a)

x ≥ a → x ∈ [a, ∞)

x < a → x ∈ (a, ∞)

--------------------------------------

Therefore:

x ≥ 7.8 → [7.8, ∞)

x < 7.8 → (-∞, 7.8)

x ≤ 7.8 → (-∞, 7.8]

x > 7.8 → (7.8, ∞)

Hatshy [7]

Answer:

1. 29.67°

2. 68.96°

3. 89.85°

Step-by-step explanation:

1. Reference angle = x

Opposite = 45 cm

Adjacent = 79 cm

Therefore:

tan(x) = \frac{45}{79}

tan(x) = 0.569620253

x = tan^{-1}(0.569620253)

x = 29.67 (nearest hundredth)

2. Reference angle = B

Opposite = 14

Hypotenuse = 15

Therefore:

sin(B) = \frac{14}{15}

sin(B) = 0.93333

B = sin^{-1}(0.93333)

B = 68.96 (nearest hundredth)

3. Reference angle = x

Adjacent = 238,900 mi

Hypotenuse = 92,955,807 mi

Therefore:

cos(x) = \frac{238,900}{92,955,807}

x = cos^{-1}(\frac{238,900}{92,955,807})

x = 89.85 (nearest hundredth)

Ameila bought roast beef for $6.85 per pound find the total cost if ameila bought 4 pounds of roast beef justify your answer by
Nadusha1986 [10]

The question states, "$6.85 per pound find the total cost if Ameila bought 4 pounds".

So you know she bought 4 pounds costing $6.85.

It is equal to 4(6.85).

If you apply the distributive, it will be 6.85+6.85+6.85+6.85.

This is equal to 27.4
