Andrea has $18 to spend she spent $6.50 including tax to buy a notebook she needs to save 5.75 but she wants to buy a snack if candy bars cost $1.15 per package including tax what inequality would show the maximum number of packages that Andrea can buy love you any quality by showing your work and steps
Answer:
Andrea can only buy one snack.
Step-by-step explanation:
okay so since she had 18 dollars at first write it down. so,you would simply put $18 vertically (up) and then Andrea spent 6.50 on a notebook. write that down as well. so now under the "$18" write -6.50. that equals $11.5. but, Andrea needs to save 5.75. so, subtract that from the 11.5 that you wrote under 6.50. (a little check up right here/clarification) write $18-$6.50=$11.5 DO THIS VERTICALLY (UP) ! okay so now that you have that $11.5 written down, subtract 5.75 (for Andreas savings) $11.5-5.75= 5.75.
so you're work should look like this
$18.
$-6.50
-----------
$11.5
$-5.75
-------------
$5.75
just make sure you add the top ones like you know, the carry the one and stuff, just so she doesn't assume you copied of the internet . have a good day! i wish you the best of luck on this assignment !

The volume of a cylindrical water tank is 2783π cubic feet. If the radius is 11 feet, what is the height of the tank?
Answer:
23 feet
Step-by-step explanation:
Givens
Volume = pi r^2 h
r = 11
V = 2783 pi
Solution
2783 pi = pi 11^2 * h Cancel the 2 pi's
2783 = 11^2 h Expand 11^2
2783 = 121 * h Divide by 121
2783/121 = h
h = 23 feet
A political candidate has asked you to conduct a poll to determine what percentage of people support her. If the candidate only wants a 2% margin of error at a 97.5% confidence level, what size of sample is needed?Give your answer in whole people.
Answer:
The sample size is [tex]n = 3139 [/tex]
Step-by-step explanation:
From the question we are told that
The margin of error is [tex]E = 0.02[/tex]
From the question we are told the confidence level is 97.5% , hence the level of significance is
[tex]\alpha = (100 - 97.5% ) \%[/tex]
=> [tex]\alpha = 0.025[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 2.241 [/tex]
Generally we will assume the sample proportion to be [tex]\^ p = 0.5[/tex]
Generally the sample size is mathematically represented as
[tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]
=> [tex]n = [\frac{2.241}{0.02} ]^2 *0.5 (1 - 0.5 ) [/tex]
=> [tex]n = 3139 [/tex]
it Given that f (x) = xsquared 2+3x+2 find f(0) the values of x for which f (x) =0
Step-by-step explanation:
f(x) = x^2 + 3x + 2
f(0) = (0)^2 + 3(0) + 2
= 2.
f(x) = 0
x^2 + 3x + 2 = 0
(x + 1)(x + 2) = 0
x + 1 = 0 x + 2 = 0
x = -1 x = -2
hence x = -1 or -2.

Each day, Yumiko exercises by first doing sit-ups and then running. Use her data and the trend line y = 9x + 5 to estimate Yumiko’s exercise time if she runs 5 mi.
Estimate: about ______ minutes
Answer:
50
Step-by-step explanation:
Given the trend line equation :
y = 9x + 5
Exercise time if she runs 5 miles :
From the trend line equation :
y = exercise time
x = miles ran
If she runs 5 miles ; then x = 5
y = 9(5) + 5
y = 45 + 5
y = 50
