1. H+S=40
2. 19H+25S=922
From 1,
19H+19S=760
Subtract this from 2 to eliminate H,
19H+25S-19H-19S=922-760
6S=162
Solve for S, then use either equation to solve for H.
Answer:
Her first coupon ti be used is $50 off a purchase above $300
Final purchase price= $340
Step-by-step explanation:
Marie has two coupons
one for a 15% discount and one for $50 off any purchase above $300.
The stores allow the two coupons to be combined and she spends a total of $450.
Her first coupon ti be used is $50 off a purchase above $300.
So Marie have $400 now
15% off $400= 400-(0.15*400)
15% off $400 = 400-60
15% off $400 =$ 340
For us to determine the number of points that is needed in order to surpass or succeed the hardest setting of the game level 5, we use first the function g(x) to determine the total points required for the lower level.
g(x) = 8(2)(x) + 1
We substitute the x of the function with 5 since we are in level 5.
g(5) = 8(2)(5) + 1 = 81
Then, to determine the points for the hardest setting, we multiply the points by 3 as given in function h(x).
h(x) = 3(81) = 243
Hence, to succeed the hardest setting of level 5, one needs a total of 243 points.
Options:
A.
All survey respondents
B.
The proportion of customers who say they are satisfied with their service
C. All customers who use the drive-thru window of this fast food restaurant
D. All customers of this restaurant
Answer:A. All survey respondents
Step-by-step explanation: A population is the total number of people or a particular organism staying in a particular place or from where a sample can be gotten which is to be used for an experiment.
A survey is a research procedure used to obtain data from a pre-determined group of people,this data is about their own view about a given topic of interest in the research.
Given:
The value is 
.
To find:
The value as a base 2 logarithm.
Solution:
We know that,
where, a is any positive value.
We have,
Using the above property of logarithm, we get
For a=2,
Therefore, the given value as a base 2 logarithm can be written as 
.
