Answer:

11 73/78 ≈ 11.9359 (not 14)

Step-by-step explanation:

The similarity statement tells us ...

QS/QR = FG/FH

QS = QR·FG/FH

13x -14 = 154(55/60) = 847/6

Adding 14 = 84/6, we have ...

13x = 931/6

x = 931/78 = 11 73/78 . . . . . . . divide by 13

<em>Comment on the question</em>

You get a nice integer answer for x if the similarity statement is written ...

∆FGH ~ ∆QRS . . . . . . . note the letters are in alphabetical order

Then you have ...

QS/QR = FH/FG

13x -14 = 154(60/55) = 168

13x = 182

x = 14

This nice answer to a nice similarity statement leads us to believe the question has an error in it.

We suspect you are expected to provide x=14 as the answer, even though that is NOT the answer to the question <em>as written</em>. You may want to discuss this with your teacher.

A school is building a rectangular soccer field that has an area of 6000 square yards. The soccer field must be 40 yards longer

kogti [31]

Area is 6000 yd2

LW = 6000

field must be 40 yards longer than its width

L = W + 40

Replace L with W+40 in 1st equation to solve for Width

(W+40)(W) = 6000

W2 + 40W - 6000 = 0

This is a quadratic but is factorable

Factors of -6000 that add to 40 are (100)(-60)

(W+100)(W-60) = 0

W = -100 or W = 60

Since the width will not be negative discard -100

The width is 60 yards

Length is W+40 = 100 yards

You are traveling by car from Covington, GA to Savannah, GA – a distance of about 240 miles. You are moving at 60 miles per hour

Degger [83]

Answer:

Speed = Distance/Time. so if you rearrange this it means that you get Time = Distance/Speed. Therefore 240/60 = 4 then you just think of doing miles(distance)/Miles per hour(speed) which leaves you with 4 hours which=C

Step-by-step explanation:

Sometimes to make it easier i use a triangle from this equation, you cover up what one you want and then you do what it says. If you cover up distance then you are left with speed x time. Likewise if you cover up speed. Speed = Distance / Time.
