A student pays for 8.9 pounds of apples with a 10$ bill. Its $1.09 per pound. How much change does the student receive? What do you do first to solve the problem?
Answer:
$0.299
Step-by-step explanation:
Given that :
Pounds of apple purchased = 8.9 pounds
Price per pounds of apple = $1.09
Bill issued = $10
First, we calculate the total cost of 8.9 pounds of apple :
(Number of pounds * price per pound)
($8.9 * 1.09) = $9.701
Amount of Change :
Bill issued - total cost
$10 - $9.701
= $0.299
Answer:
9n + 15
Step-by-step explanation:5XN + 5X3 + 4N = 5n + 15 + 4n = 9n + 15
Answer:
A. x = -2, 5/2
B. Minimum
Vertex: (1/4, -81/8)
C. Draw a concave up graph connecting the x-intercepts, vertex and the y-intercept
Step-by-step explanation:
f(x) = 2x² - x - 10
2x² - x - 10 = 0
2x² - 5x + 4x - 10 = 0
x(2x - 5) + 2(2x - 5) = 0
(x + 2)(2x - 5) = 0
x = -2, 5/2
Vertex: (h,k)
h = midpoint of the x-intercepts (due to symmetry)
h = (-2 + 5/2) = 1/4
k = f(1/4)
k = 2(1/4)² - 1/4 - 10 = -81/8
Vertex: (1/4, -81/8)
y-intercept: when x = 0
2(0)² - 0 - 10 = -10
Draw a concave up quadratic connecting thr following points:
(-2,0)
(0,-10)
(1/4,-81/4)
(5/2,0)
Answer: I dont know how to draw graphs that good, but here is a step by step explenation https://www.algebra.com/algebra/homework/word/finance/Money_Word_Problems.faq.question.1072873.html
since 2. is the same one i solved before i didn’t put the work. Hope this helps :))))
