Answer:

solution given:

m<a=m<c

3x+40=x+50

3x-x=50-40

x=10/2=5

now

<a=3×5+40=55°

m<a=55° is your answer

Answer:

55°

Step-by-step explanation:

It is assumed the angles A and C are congruent:

3x + 40 = x + 50
3x - x = 50 - 40
2x = 10
x = 5

m∠A = 3*5 + 40 = 55°

The otherSites Squared10.A cylinder has a diameter of 12 meters and a height of 9 meters. What is thetotal surface area of the c

Gelneren [198K]

The total surface area of a cylinder is given by the formula

$\begin{gathered} A_{cylinder}=2circular\text{ area+curved surface area} \\ =2\pi r^2+2\pi rh \end{gathered}$

Given diameter, d=12meters, we will solve for radius

$\begin{gathered} \text{diameter,d}=2\times radius,r \\ d=2r \\ r=\frac{d}{2} \\ r=\frac{12m}{2} \\ r=6m \end{gathered}$

The height is given as 9meters

Substituting for r and h in the formula will give

$\begin{gathered} A_{cylinder}=2\pi r^2+2\pi rh \\ r=6m;h=9m;\pi=3.14 \\ A_{cylinder}=2\times3.14\times6^2+2\times3.14\times6\times9_{} \end{gathered}$ $\begin{gathered} A_{cylinder}=6.28\times36+6.28\times54 \\ =226.08+339.12 \\ =565.2m^2 \end{gathered}$

Hence the surface area of the cylinder is 565.2m²

Which graph represents the solution to the given system? y=5x+4; y=5x-3

Mars2501 [29]

Hello from MrBillDoesMath!

Answer:

The lines do not intersect

Discussion:

Where do the lines intersect?

5x + 4 = 5x - 3 => subtract 5x from both sides

4 = -3 => NO WAY! The lines do not intersect

Thank you,

MrB

You are reaching the price of MP3 players.Yiu found an average price of $58.80. One MP3 player cost $56 and another cost $62. Fi

tino4ka555 [31]

The price of third MP3 Player is $58.4

Further explanation:

Given

Price of first MP3 player= p1= $56

Price of second MP3 Player = p2= $62

Price of third MP3 Player=?

Average = X = $58.80

The formula for average is:

$X =\frac{Sum}{No.\ of\ items}$

We have 3 items.

Putting the values

$58.80=\frac{56+62+p_3}{3}\\58.80*3=118+p_3\\176.4=118+p_3\\p_3=176.4-118\\p_3=58.4\ dollars$

The price of third MP3 Player is $58.4
