Answer:
She should buy 7 large pieces of fabric to make 7 scarves
Step-by-step explanation:
Length of side of each square piece =
Area of 1 square piece =
Doris uses 8 square pieces to make one scarf.
Area of 8 square pieces = Area of 1 scarf =
Area of 7 scarves =
Length of fabric bought by Doris =
Breadth of fabric brought by Doris = 2 yards
Area of fabric brought by Doris =
So,She should buy no. of large pieces of fabric to make 7 scarves =
Hence She should buy 7 large pieces of fabric to make 7 scarves
Answer:
The solution to the system of equations is (-6, 3)
Step-by-step explanation:
Plot both lines on a graph, find where they intersect IF they even intersect at all like in this case, and boom there's your answer. Hope that helps and have a good rest of your day.
Step-by-step explanation:
sin∅=-3/4 in 4 quadrant which sine is negative there
using soh cah toa
sin=opp/hyp
where our opp=-3 and our hyp=4
using pythagoras theorem
hyp²=opp²+adj²
(4)²=(-3)²+adj²
16=9+adj²
16-9=adj²
adj²=7
adj=√7
from soh cah toa
cos∅=adj/hyp
cos∅=√7/4
Answer:
-1/2 (-2x + 4y)= x - 2y
Step-by-step explanation:
-1/2 (-2x + 4y)
x - 2y
Step1-divide the first term of the numerator by the first term of the denominator,and put that in the answer.
Step2-multiply the denominator by that answer,put that below the numerator.
Step3-Subtract to create a new polynomial.
