Olivia needs 34 inches of copper wire for an experiment. the wire is sold by the centimeter. given that 1 inch = 2.54 centimeters, how many centimeters of wire does olivia need?

86.36cm

Step-by-step explanation:

1 inch = 2.54 cm

34 inch = ???

multiply 34 and 2.54 ( like X )

34×2.54 = 86.36cm

ANSWER:  

Olivia needs 34 inches of copper wire for an experiment .The wire required in centimeters is 86.36 cm.

SOLUTION:

Given, Olivia needs 34 inches of copper wire for an experiment.  

The wire is sold by the centimeter.  

Given that 1 inch = 2.54 centimeters

We have to find how many centimeters of the wire does Olivia need for her experiment.

We just need to convert the given wire in inches to wire in centimeters.

Wire in inches = 34 inches  

= 34 x 1 in = 34 x 2.54 cm = 86.36 cm

Hence, the wire required in centimeters is 86.36 cm.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
