Sophie has 5 pieces of string that are 4 yards each. She uses 3 pieces that are each 3 feet long. How much string does Sophie have left?2 feet


2 yards


31 feet


51 feet

Answers

Alright, lets get started.

Sophie has 5 pieces of string that are 4 yards each.

1 yards = 3 feet,

So, 4 yards = 4 * 3 =12 feet

Total number of string she has = 5 piece

So, total length she has = 5*12 = 60 feet

It means she had 60 feet string in starting.

Now, She uses 3 pieces that are each 3 feet long, means

She uses = 3*3 = 9 feet

So, remaining string length will be = 60 - 9 = 51 feet

Means 51 feet string does Sophie have. : Answer

Hope it will help :)

I = P x r x t

P is the principal amount, $420.00.

r is the interest rate, 3.5% per year

t is the time involved, 5 years

420 × 0.035 × 5 = 73.50

73.50 + 420 = 493.5

How are perpendicular lines similar to intersecting lines?how are they differrent ?

Answers

Perpendicular lines are connected, and form two 90º angles. Although they connect, they do not necessarily have to "cross over" each other. Intersecting lines, on the other hand, must cross over each other to form 4 angles. Note that the angles between intersecting lines do not have to be 90º.
Think of perpendicular lines like a Upper case T
Think of intersecting likes like an addition sign: +

Similarities: Both sets of lines create angles, and in both sets the two lines are connected in some way
Differences: Perpendicular lines ALWAYS form 90º angles, but intersecting lines don't have to. 

Hope this helps!
well perpendicular lines intersect but make a right angle but intersecting lines don't hope that helps

A circular lampshade with a diameter of 14 inches has a length of wire that goes around exactly one time. How many inches of wire are needed to go around the lampshade exactly one time?

Answers

the questions is how long the circumference of the lampshade is, and that is given by:
c = diameter*pi
c = 14*3.14
c = 43.96
so, there are needed 43.96 inches of wire to go around the lampshade one time
