If KJ=4 and KM= 2, find ML

adelina 88 [10]

Answer:

Step-by-step explanation:

(whole secant) * (external part) = (tangent)^2

(KL) * (KM) = KJ^2

(KM+ ML) * KM = KJ^2

(2+ ML) * 2 = 4^2

(2+ ML) * 2 =16

Divide each side by 2

(2+ ML) = 8

Subtract 2 from each side

ML = 6

Elena is designing a paint can with thickness ttt millimeters and height hhh centimeters. She calculates that the thickness of t

Degger [83]

Answer:

$t \ge h$ and $t + 0.5h \le 12.0$

Step-by-step explanation:

Given

$t= thickness$

$h =height$

From the first statement, we have that:

$t\ mm \ge 0.1 * h\ cm$

Convert mm to cm

$t\ * 0.1*cm \ge 0.1 * h\ cm$

$t\ *0.1 \ge 0.1 * h$

Divide both sides by 0.1

$t \ge h$

From the second statement, we have that:

$Cost \le 12.2$

Substitute 0.2 + t + 0.5h for Cost

$0.2 + t + 0.5h \le 12.2$

Collect Like Terms:

$t + 0.5h \le 12.2-0.2$

$t + 0.5h \le 12.0$

So, the inequalities are:

$t \ge h$ and $t + 0.5h \le 12.0$

How do I find the miles per gallon?

Eddi Din [679]

Answer:

Get the miles traveled from the trip odometer, or subtract the original odometer reading from the new one.

Divide the miles traveled by the amount of gallons it took to refill the tank. The result will be your car's average miles per gallon yield for that driving period.
