Answer:

x = 12, sides = 23

Step-by-step explanation:

\overline{ST}=2x-1\\\overline{SU}=5x-37\\\overline{TU}=x+11

Since \triangle{STU} is equilateral, all three sides are equal. Therefore:

\left[\begin{array}{l}y=2x-1\\y=5x-37\\y=x+11\end{array}\right]

Substituting y = x + 11:

\left[\begin{array}{l}x+11=2x-1\\x+11=5x-37\end{array}\right]

Solving for x:

x+11=2x-1\\11=x-1\\12=x

Substituting x = 12:

y=x+11\\y=12+11\\y=23

Thus, <em>x</em> = 12 and the length of each side is 23.

<h3>Answer:  22</h3>

===============================================

Explanation:

  • x = measure of angle 1 = angle WXY
  • 2x = twice the measure of angle 1 = measure of angle 2 = angle YXZ

The two angles mentioned combine to form angle WXZ which is 66 degrees.

angle1+angle2 = angle WXZ

x+2x = 66

3x = 66

x = 66/3

x = 22

Angle 1 is 22 degrees and angle 2 is 22*2 = 44 degrees.

Check:

angle1+angle2 = 22+44 = 66 = angle WXZ

The cost to manufacture t shirts can be represented by the function c(x)=10.5x complete the following statement about the functi
Advocard [28]

For this case we have:

Cost of manufactures of T-shirts C(x)=10.5x

where x represents the number of T-shirts

Part A:

Substituting x = 8 in the total cost equation you have to:

C (8) = (10.5) (8)\\\\C (8) = 84\\

Thus, the cost of 8 shirts will be C (8) = 84\\

Part B:

If x = 12 then

C (12) = (10.5) (12)\\\\C (12) = 126\\

Thus, the cost of 12 shirts will be C (12) = 126\\

Answer:

C (8) = 84\\\\C (12) = 126\\\\

The scale on the architectural plans for a new house is 1 in. equals 4 ft. Find the length and width (in ft) of a room that meas
Oksi-84 [34.3K]

Answer: the actual length and width of the room is 24ft by 36ft

Step-by-step explanation:

The scale on the architectural plans for a new house is 1 in. equals 4 ft. This means that every 1 inch on the on the architectural plan represents 4 feet on the actual building.

Therefore, if the length of the room as measured on the drawing is 6 inches, the actual length of the room will be

6 × 4 = 24 feet

Also, if the width of the room as measured on the drawing is 9 inches, the actual width of the room will be

9 × 4 = 36 feet
