Answer:
Quick Market is the better buy.
...........................
To solve this in your head:
1) You can see that "6 apples for (about) $1.20" is about 20 cents each.
2) For the other apples to be 20 cents each, the price for 8 would have to be about $1.60
3) Because the cost of 8 apples is less than $1.60, then the Quick Market apples are cheaper than the other ones.
The Quick Market will be the place for better buy than Stop and Save.
Comparison of rates for better buy: Find the rate of one unit. Compare the rates to decide the better buy.Given in the question,
Total amount paid for 8 apples at The Quick Market = $1.45 Total amount paid for 6 apples at Stop and Save = $1.22Rate of apples at The Quick Market = [tex]\frac{\text{Total amount paid}}{\text{Number of apples}}[/tex]
= [tex]\frac{1.45}{8}[/tex]
= $0.18125
≈ $0.18 per apple
Rate of apples at Stop and Save = [tex]\frac{1.22}{6}[/tex]
= $0.20333
≈ $0.20 per apple
Since, $0.18 is less than $0.22, The Quick Market will be the place for better buy than Stop and Save.

given g(x) √x-4 and h(x) = 2x - 8
what are the restrictions on the domain of g • h?
x ≥ ____
Answers
Answer:
6
Step-by-step explanation:
Given : g(x) = and h(x)=2x-8.
g*h(x) =(2x-8).
We have square root(x-6) in composite function f*h(x).
So, we need to find the domain, we need to check for that values of x's, square root(x-4\6) would be defined.
Square roots are undefined for negative values.
Therefore, we can setup an inequality for it's domain x-6≥0.
Adding 4 on both sides, we get
x-6+6≥0+6.
x≥6.

At a department store, the price of a freezer is marked up 15% to $450.50.
What was the price of the freezer BEFORE the mark up?
Answers
Answer:
The price was $391.30.
Step-by-step explanation:
We can answer this using algebra:-
Let the original price be $x, then:
x + 15% of x = 450
x + 0.15x = 450
1.15x = 450
x = 450/1.15
x = 391.304

A rectangular park is 135 yards long and 90 yards wide.
Give the length and width of another rectangular park that has the same perimeter but a smaller area.
Answers
Answer:
l = 140 yards , w = 85 yards
Step-by-step explanation:
1). l = 135 yards , w = 90 yards
P = 2 × 135 + 2 × 90 = 450 yards
A = 135 × 90 = 12,150 yards²
2). l = 140 yards , w = 85 yards
P = 2(140 + 85) = 450 yards
A = 140 × 85 = 11,900 yards²

It is a trinomial because it follows the pattern of x^2 + bx + c. In this case, x^2 - 10x + 25. Also, it only has three numbers and two operation symbols, signifying a trinomial (three = tri).

In △ACD, if AC ≅ AD, m∠A = (3x – 4)°, m∠C = (5x + 1)°, and m∠D = (7x – 27)°, find x and the measure of each angle. *
Answers
Answer:
x = 14
A = 38
B = 71
C = 71
Step-by-step explanation:
Since we have a triangle, the addition of the measure of all the measure of the angles give 180
Thus;
3x-4 + 5x + 1 + 7x-27 = 180
15x-30 = 180
15x = 180 + 30
15x = 210
x = 210/15
x = 14
To get the measure of each of the angles, we substitute for x
A = 3x-4 = 3(14) - 4 = 38
B = 5x + 1 = 5(14) + 1 = 70 + 1 = 71
C = 7x - 27 = 7(14) - 27 = 98-27 = 71
A.) how much does it cost to buy 5 tickets?
B.) How many tickets can buy with $130?
Answers
Answer:
A) $77.50
B) 8 tickets
Step-by-step explanation:
A) c(x) = 17.5x - 10
Substitute 5 for x
c(x) = 17.5(5) - 10
Multiply
c(x) = 87.5 - 10
Subtract
c(x) = 77.5
B) 130 is the cost, so substitute 130 for c(x)
130 = 17.5x - 10
Add 10 to each side to move the constants to one side
140 = 17.5x
Divide each side by 17.5 to isolate the variable

Step-by-step explanation:
0.8 - 3.2x < -2 - 2.8x
Add 2.8x to both sides.
0.8 - 0.4x < -2
Subtract 0.8 from both sides.
-0.4x < -2.8
Divide both sides by -0.4. Remember that when you multiply or divide both sides of an inequality by a negative number, the inequality symbol changes direction.
