Michelle has a piece of yarn measuring 7 yards. How many 1-inch strips can be cut from the yarn

Mathematics
1 answer:
slavikrds [6]3 years ago
7 0

Answer:

252 pieces

Step-by-step explanation:

We need to convert 7 yds to inches

1 yd = 3 ft

so 7 yds * 3ft/yd = 21 ft

We know that 1 ft = 12 inches

so

21 ft * 12 inches/1 ft =252 inches

7 yds = 252 inches

We can cut 252 inch pieces from  the yarn

If the slope of line L is -2/5, what is the slope of line m so that line l and line m are perpendicular?
ki77a [65]
Perpendicular lines have negative reciprocal slopes. So if the slope is -2/5...to find the negative reciprocal, " flip " the slope and change the sign.
So we flip -2/5 and we get 5/-2...and now we change the sign...and we get 5/2. So our perpendicular slope will be 5/2.

What are zeroes of f(x) =x^2-x-2
allochka39001 [22]
You have to factor this...
 So you have started with this...

x²-x-2=0
If you factor this you will get

(x+1)(x-2)=0

This gives you two solutions...
x=-1, x=2
Hope this helps! Give me a five-rate and a thanks!

7 Carolina fosters 5 puppies. For each puppy she buys a crate that costs c dollars
Elena L [17]

2 Answers:

Choice B and Choice C

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

Reasoning:

c = cost of one crate (some unknown amount in dollars)

c+20 = cost of a crate and a leash

5(c+20) = cost of five sets of items mentioned

5(c+20) = 475 is one equation we can form

5c+100 = 475 is another equation we can form

I used the distributive rule to go from 5(c+20) to 5c+100.

The 100 indicates that the five leashes combine to $100, since 5*20 = 100.

The 5c represents the cost of all five crates combined.

So 5c+100 is another way to express the total cost of all five crates and all five leashes.

---------------

Side note: Solving either equation leads to c = 75, meaning that each crate costs $75.
