Amy uses two thirds of a yard fabric for each pillow she makes how many yards of fabric will she need in order to make 8 pillows

Aneli [31]

2/3 yard= 1 pillow

To find the total yards needed for 8 pillows, multiply 2/3 yard per pillow by 8 pillows.

= 2/3 * 8
multiply numerators; multiply denominators

= (2*8)/(3*1)

= 16/3
convert to a mixed number

= 5 1/3 yards needed

ANSWER: 5 1/3 yards is needed to make 8 pillows.

Hope this helps! :)

Use synthetic division to solve (x3 + 1) ÷ (x – 1). What is the quotient?

mamaluj [8]

Steps:

Use the divisor and find x :
x - 1 = 0 **add 1
x= 1
Now we will use the 1 in dividing:

take the coefficients from in front of all terms
** make sure you include 0's for x^2 and x since you have to have all terms

set it up with a 1 in a box:

1| 1 0 0 1 **bring the first number down
____________
1 **multiply the boxed number by the first number and add it to the second number

1| 1 0 0 1
____+1_____ **repeat with the rest of the terms
1 1

1| 1 0 0 1
___+1_+1_+1
1 1    1 2
**when you're done, use the new numbers to write an equation starting with a term with a degree one less than the previous equation.
**since there is a remainder, rewrite it divided by the original divisor

final answer:
x^2 + x + 1 + (2/ x -1)

Jarvis left out a statement from the proof shown.which statement is best explained by the corresponding angles postulate

Salsk061 [2.6K]

The postulate of the corresponding angles establishes that when a transversal line cuts two parallel lines, the corresponding angles are congruent. These angles are on the same side of the parallel lines and on the same side of the transversal line.

Then, if we based on this definition and analize the figure attached, we can notice that the angles ∠1 and ∠3 are corresponding angles, so they are congruent. In this case the angle ∠1 is internal and the angle ∠3 is external.

The answer is: ∠1 and ∠3 are congruent (See the image attached).
