Answer:

No solutions

Step-by-step explanation:

If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations. ... When the lines are parallel, there are no solutions, and sometimes the two equations will graph as the same line, in which case we have an infinite number of solutions.

You can buy shampoo in a 5-ounce bottle for $2.49 or in a 15-ounce bottle for $9.69.
xz_007 [3.2K]
The 5 ounce bottle for $2.49 is a better deal because the unit price is .49 cents PER ounce, where as the 15 ounce bottle for $9.69 is .64 cents PER ounce.

$9.69/15 = $0.64
$2.49/5 = $0.49

Nookie1986 [14]

Answer:

29

Step-by-step explanation:

We can use the pythagorean theorem to find the length of the ladder

{20}^{2}  +  {21}^{2}  = c {}^{2}

400 + 441 =  {c}^{2}

841 =  {c}^{2}

c = 29

The answer is 29

The art museum had a total of 224 visitors on Tuesday. Visitors older than 18 paid $12 for admission. Visitors 18 years or young
dimaraw [331]
Given:
total of 224 visitors
older than 18  paid $12
18 and below paid $8
total collection 2,520

Let l be visitors older than 18 and m be visitors 18 and below.

l + m = 224
12l + 8m = 2,520

l = 224 - m
12(224 - m) + 8m = 2520
2688 - 12m + 8m = 2520
-4m = 2520 - 2688
-4m = -168
m = -168/-4
m = 42    number of visitors 18 and below.

l = 224 - m
l = 224 - 42 
l = 182 number of visitors older than 18.

12(182) + 8(42) = 2520
2184 + 336 = 2520
2520 = 2520

Snow Dome Ski Resort has 75 inches of snow. It is currently snowing there at a rate of 1 inch per hour. Mt. Winterpark Ski Resor
Nastasia [14]

Answer:

a. See explanation for table

b. The 7th hour

Step-by-step explanation:

Given

Ski Resort

Base\ Snow = 75in

Rate = 1in hourly

Mt. Winterpark

Base\ Snow = 68in

Rate = 2in hourly

First, we need to illustrate the amount of snow as an equation in both cases.

Amount = Base\ Snow + Rate * Time

Let x be number of hours. and y be the amount of snow

So:

Ski Resort

y= 75 + 1* x

y= 75 + x

Mt. Winterpark

y= 68 + 2 * x

y= 68 + 2x

Next, we make a table to show the data.

When x = 0

Ski Resort: y = 75 + 0 = 75

Mt. Winterpark: y = 68 + 2(0) = 68

When x = 1

Ski Resort: y = 75 + 1 = 76

Mt. Winterpark: y = 68 + 2(1) = 70

When x = 2

Ski Resort: y = 75 + 2 = 77

Mt. Winterpark: y = 68 + 2(2) = 72

When x = 3

Ski Resort: y = 75 + 3 = 78

Mt. Winterpark: y = 68 + 2(3) = 74

When x = 4

Ski Resort: y = 75 + 4 = 79

Mt. Winterpark: y = 68 + 2(4) = 76

When x = 5

Ski Resort: y = 75 + 5 = 80

Mt. Winterpark: y = 68 + 2(5) = 78

When x = 6

Ski Resort: y = 75 + 6 = 81

Mt. Winterpark: y = 68 + 2(6) = 80

When x = 7

Ski Resort: y = 75 + 7 = 82

Mt. Winterpark: y = 68 + 2(7) = 82

When x = 8

Ski Resort: y = 75 + 8 = 83

Mt. Winterpark: y = 68 + 2(8) = 84

When x = 9

Ski Resort: y = 75 + 9 = 84

Mt. Winterpark: y = 68 + 2(9) = 86

When x = 10

Ski Resort: y = 75 + 10 = 85

Mt. Winterpark: y = 68 + 2(10) = 88

Hence, the table is:

x ---- Ski Resort ---- Mt. Winterpark

0 --------75 ----------- 68

1 --------76 ----------- 70

2 --------77 ----------- 72

3 --------78 ----------- 74

4 --------79 ----------- 76

5 --------80 ----------- 78

6 --------81 ----------- 80

7 --------82 ----------- 82

8 --------83 ----------- 84

9 --------84 ----------- 86

10 -------85 ----------- 88

(b)

From the table, the amount of snow is the same at the 7th hour and the snow is 82 inches
