Answer: Well... does it give you the approximate length or actual length of the butterfly? If so, you would take that length and multiply it by 5. That would give you the length of the 5 butterfly lined up together.

If it does not give you the approximate length or actual length, look up the length on google. (Google Answer- Size: 2.5" - 4.0" range.)

Take that and multiply it by five to get the length of the 5 butterflies.

Use the following diagram to find the angle measures of the triangle, rounded to the nearest degree.

nadezda [96]

Answer:

m∠A = 30°

m∠B = 80°

m∠C = 70°

Step-by-step explanation:

By applying cosine rule in the given triangle,

b² = a² + c² - 2ac[cos(∠B)]

From the given triangle,

a = 14 m

b = 28 m

c = 24 m

(28)² = (14)² + (24)² - 2(14)(24)cos(B)

784 = 196 + 576 - 672cos(∠B)

cos(∠B) = 0.1786

∠B = $\text{cos}^{-1}(0.1786)$

∠B = 79.71°

∠B = 80°

By applying sine rule in the given triangle,

$\frac{\text{sinA}}{a}= \frac{\text{sinB}}{b}= \frac{\text{sinC}}{c}$

$\frac{\text{sinA}}{14}= \frac{\text{sin(79.71)}}{28}= \frac{\text{sinC}}{24}$

$\frac{\text{sinA}}{14}= \frac{\text{sin(79.71)}}{28}$

$\text{sinA}= \frac{\text{sin(79.71)}\times 14}{28}$

sinA = 0.491958

A = 29.47°

A ≈ 30°

By applying triangle sum theorem,

m∠A + m∠B + m∠C = 180°

30° + 80° + m∠C = 180°

m∠C = 70°

Of the 28 muffins left in the fridge, 16 of them have blueberries. What

Igoryamba

Answer:

43% or 3/7

Explanation: Subtract 16 from 28 to get the number of muffins with no blueberries. Then you get 12/28 which is simplified to 3/7 or 43 percent.
