Answer:

x = 35.68533471.. degrees

Step-by-step explanation:

5-7-12 right triangle

According to Soh Cah Toa, the angle you are looking for is sin(x) = 7/12. Solve.

Erica plotted the three towns closest to her house on a graph with town A

marta [7]

First, determine the distances from the towns.
Town A to Town B: Opposite angle C
d = sqrt ((12 - 7)^2 + (9 - 9)^2)
d = 5
Town B to Town C: Opposite Angle A
d = sqrt ((7 - 1)^2 + (9 - 1)^2)
d = 10
Town A to Town C: Opposite Angle B
d = sqrt (12 - 1)^2 + (9 - 1)^2)
d = 13.6
The angle with largest measure is the one opposite the greatest distance. Thus, the arrangement would be: C, A, B.

Maria has a cell phone and she gets charged for data each month. She is

aliina [53]

If it costs $12.5 for every GB and we use 8 then 12.5*8=$100. So if our flat rate now is $70 we would loose 100-70=$30

So Maria would loose $30 a month if she pays per GB

5x=15 y 2x=6 Son ecuaciones equivalentes? PORFAVOR AYÚDENME ES EMERGENCIA

mihalych1998 [28]

Si, los dos son iguales

Cuando haces 5x=15, la división dice que x = 3. Para 2x=6 puedes usar el resultado de x=3 de la problema de antes, y cuando te usas esto va a ver que 2 de x cuando x=3 es igual a 6, y por eso 5x=15 y 2x=6 son equivalentes.

Answer:

$\boxed{\text{1172 in}^{2}}$

Step-by-step explanation:

SA = SA(prism) + SA(cylinder) – 2SA(cylinder base)

1. Surface area of rectangular prism

The formula for the surface area of a rectangular prism is

S = 2(lw + lh + wh)

Data:

l = 16 in

w = 11 in

h = 11 in

Calculations:

2(Top + Bottom) = 2lw = 2 × 16 × 11 = 352 in²

2(Front + Back) = 2lh = 2 × 16 × 11 = 352 in²

2(Left + Right) = 2wh = 2 × 11 × 11 = 242 in²

Total area = 946 in²

2. Surface area of cylinder

A = A(top) + A (base) + A(side) = 2A(base) + A(side)

Data:

d = 8 in

h = 9 in

Calculations:

r = ½d = ½ × 8 = 4 in

$\begin{array}{rcl}SA & = & 2\pi r^{2}+ 2\pi rh \\& = & 2 \times 3. 14\times 4^{2} +2\times 3. 14 \times 4\times 9\\& = & 6.28\times 16 + 226.08\\& = & 100.48 + 226.08\\& = & 326.56 \text{ in}^{2}\\\end{array}$

3. Excluded area

Excluded area = 2A(base) = 100.48 in²

4. Total area

$A = 946 + 326.56 - 100.48 \approx \boxed{\textbf{1172 in}^{2}}$
