Answer:
$1.90
Step-by-step explanation:
16.80 - 1.60 = 15.20, since we are finding the price of each bottle of juice.
1) Set up and equation equated to 15.20.
8x = 15.20
x = 15.20/8
x = 1.90
Therefore, each bottle of juice costs $1.90.

Jackson has a gift card for $120 to use at a department store. he wants to purchase 2 shirts and 3 pairs of pants with his gift card. if x represents the cost of the shirts and y represents the cost of the pants, what are the domain and range of this relationship?
0 ≤ x ≤ 60
The range of this relationship can be defined as,0 ≤ y ≤ 40
Definition of Domain and Range
The set of all the possible input values for which the provided function is defined is termed as the domain of that function.
The set of all the possible values that a given function can generate as an output is termed as the range of that function.
Forming the Relation
It is given that,
Jackson wants to purchase 2 shirts and 3 pairs of pants with his gift cardx represents the cost of the shirts and y represents the cost of the pantsThe limit of the gift card = $120Thus, the relation formed is given by,
[tex]2x + 3y \leq 120[/tex]
Domain and Range of the Given Relation
We have,

a circular field was fenced using 66 posts placed two metres apart what is the area of the field in square metres
Answer:
1386m cubic
Step-by-step explanation:
hope it helps.in case of any other question, you can count on me.good day.
The area of the circular field in square meters will be equal to, 1386 m².
What is the area?An object's area is how much space it takes up in two dimensions. It is the measurement of the number of unit squares that completely encompass a compact figure's surface. The squared unit, which is frequently expressed as inches, square feet, etc., is the accepted unit of area.
As per the given information in the question,
Total number of posts = 66
Distance between two posts = 2 meters
Then, the circumference of the area will be,
= 66 × 2 = 132 meters
Now, let's find the radius of the circle,
C = 2πr
132 = 2 × 3.14 × r
r = 132/(2 × 3.14)
r = 21.01 m
Use the formula for the area of the circle:
A = πr²
A = 3.14 × (21.01)²
A = 441.420 × 3.14
A = 1386 m²

Answer: 80 miles
Step-by-step explanation:
- 400/5 = 80
- so 80 is 1/5 of 400
hope this helps :)
Answer:
80 miles
Step-by-step explanation:
The whole journey is 400 miles, so we say that he traveled x miles, where x equals 400.
if we multiple 1/5 by x miles, then we will get how much he travels
1/5*x = 1/5*(400), since x = 400, so you can replace x with 400
1/5*x=1/5*400=400/5=80 miles

What polynomial function can Todd use to calculate the average profit
Answer:
[tex]4x^{2} -8x+4[/tex]
Step-by-step explanation:
The average profit expression is for 1 piece of furniture
The amount of furniture is another expression
So we have to multiply both expressions to get the total profit.
(2x-2) (2x-2) = 4x^2 - 4x - 4x + 4

The probability that a person wins the game is 32.1%
How to illustrate the probability?Based on the information given, the following can be depicted. It should be noted that there are 6 sides as well as 4 cards.
Therefore, the numbers on the dice i.e from 1 - 6 will be represented 4 times each. This gives a total of (4 × 6) = 24. There are also 4 cards. The total in sample space will now be:
= 24 + 4 = 28
The frequency table will be such that 28 or more has a relative frequency of 9. Therefore, the probability that a person wins the game will be:
= 9/28 = 32.1%
When you win 25% of the time, this illustrates that the number of products picked will be:
= 25% × 28
= 7 products.
The probability of participants achieving a winning score of 36 or higher in four consecutive attempts will be:

5x-4y=19
x+2=8
Solve simultaneous equation
Answer:
x = 6, y = 5
Step-by-step explanation:
5x - 4y = 19 -------> equation 1
x + 2 = 8 --------> equation 2
Step 1 : Subtract 2 on both sides in equation 2.
x + 2 - 2 = 8 - 2
x = 6
Step 2 : Substitute the value of x is equation 1.
5 ( 6 ) - 4y = 19
( 5 * 6 ) - 4y = 19
30 - 4y = 10
Step 3 : Subtract 30 on both sides.
30 - 30 - 4y = 10 - 30
- 4y = - 20
Step 4 : Multiply - 1 on both sides.
- 1 * - 4y = - 1 * - 20
4y = 20
Step 5 : Divide 4 on both sides.
4y / 4 = 20 / 4
y = 5
Hence,
x = 6
y = 5
Answer:
x = 5, y = 3/2.
Step-by-step explanation:
5x-4y=19
x+2y =8 Multiply this by 2:
2x + 4y = 16 Adding this to first equation 1:
7x = 35
x = 5
So
5 + 2y = 8
2y = 3
y = 3/2.

• find the mean
mode
median
Answer:
mean: 2.6, mode: 1, median: 1
Step-by-step explanation:
The mean is essentially the average of the data set which can be defined as: [tex]\frac{\text{sum of data set}}{\text{amount of data in data set}}[/tex]. So adding all the values together you get: [tex]26[/tex]. and counting all the numbers in the data set you find the data set has 10 numbers. This gives you the equation: [tex]\frac{26}{10} = 2.6[/tex] which is the mean
To find the mode, you find which number occurs most frequently, this is of course 1, which can really be determined by just looking at the data set for a second. all the other numbers only occur once, while 1 is in the data set 5 times. So 5 is the mode
To find the median you sort the data, from min to max, and then find the middle number. Sorting the data set gives you. -2, 1, 1, 1, 1, 1, 4, 5, 6, 8. Since this data set has an even amount of numbers, there is not going to be an exact middle. If you go the "middle" which is the 5th and 6th number, you add these two numbers and divide the sum by 2. This gives you: (1+1)/2 = 1 So the median is 1
