Select the expression that has a value of 28. (4 points)

anastassius [24]

Answer:

(8 + 4 × 6) ÷ 2 + 7

Step-by-step explanation:

8 + (4 × 6) ÷ 2 + 7 = 27

8 + 24 ÷ 2 + 7

8 + 12 + 7

8 + 4 × 6 ÷ (2 + 7) = $10\frac{2}{3}$

8 + 4 × 6 ÷ 9

8 + 24 ÷ 9

$8 + 2\frac{2}{3}$

$10\frac{2}{3}$

(8 + 4 × 6) ÷ 2 + 7 = 23

(8 + 24) ÷ 2 + 7

32 ÷ 2 + 7

16 + 7

(8 × 4) + 6 ÷ 2 − 7 = 28

32 + 6 ÷ 2 - 7

32 + 3 - 7

35 - 7

A kite is flying with its string, which is of length 60 metres, taut.The kite is 20 metres vertically above the ground.a)Find th

chubhunter [2.5K]

a) Due to you have a right triangle, in order to calculate the value of d, use the Pythagorean thorem:

$d=\sqrt[]{(60m)^2+(20m)^2}=\sqrt[]{4000m^2}\approx63.2m$

Hence, the distance d is approximately 63.2m

b) To find the angle of elevation, use the sine function of θ, as follow:

$\begin{gathered} \sin \theta=\frac{opposite}{hypotenuse}=\frac{20m}{60m}=\frac{1}{3} \\ \theta=\sin ^{-1}(\frac{1}{3})\approx19.8 \end{gathered}$

Hence, the angle of elevation is approximately 19.8°
