Answer:
$13.64
Step-by-step explanation:
you need about 1853 sheets of paper which is
1853 ÷ 500, or 3.706 reams
if 1 ream costs $3.68 then 3.706 reams costs 3.706 × 3.68 or $13.64
Well if each band needs 15.5 inches and she needs to make 12 headbands she needs 15.5 inches 12 times. Now you can add 15.5 + 15.5 +15.5 (so on) 12 times or you can do it the easier way and do 15.5 times 12. this comes out to 186 inches of ribbon. She estimated 160 inches of ribbon, this is unreasonable because it is significantly less that 186.
Note x^2 =y and rewrite this quartile equation in y and will get a quadratic what you need to solve it
f(x) = x^4 +21x^2 -100 note x^2 =y
f(y) = y^2 +21y -100
y^2 +21y -100 = 0
D = 21^2 -4(-100) = 441 +400 = 841
y_1,2 = (-21 +/- sqrt841 )/2 = (-21 +/- 29)/2 = -50/2 = - 25 and 8/2 = 4
so y_1 = - 25 and y_2 = 4
x_1,2 = sqrt(y_1) = sqrt(-25) = +/- 5i
x_3,4 = sqrt4 = +/- 2
hope this will help you
Answer:
The slope of the line that contains the points (-1, 2) and (4, 3) is:
Step-by-step explanation:
Given the points
Finding the slope between (-1, 2) and (4, 3)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [3 - 2] / [4 - (-1)]
= 1 / 5
Thus, the slope of the line that contains the points (-1, 2) and (4, 3) is:
So we are looking for the price per lb....
price / lb : so be sure and put the price divided by the lbs
10.50 / (3 1/3) = 10.50 / (10/3) = 10.50 * 3/10 = 31.5/10 = 3.15 per lb
6.25 / (2 1/2) = 6.25 / (5/2) = 6.25 * 2/5 = 12.5/5 = 2.50 per lb
so the better deal is the 2 1/2 lb turkey <==
** keep in mind, when dividing fractions, flip what u r dividing by, then multiply
