Answer:

The simplified algebraic expression to represent the height, h, of a stack in cm of n flower pots is h = 6·n + 22

Step-by-step explanation:

The given information are;

The rim height of one kind of flower pot = 6 cm

The planting height of the flower pot = 22 cm

Therefore, the total height of the flower pot = 22 + 6 = 28 cm

Stacking the flower pots of a single kind will give a linear relationship of the form, y = m·x + c between the height of the stack and the number of flower pots in the stack

Where;

m = The slope or the rate of change of the height with the number of flower pots in a stack which can be found from two points in the given table of values

c = The y-intercept or height at the start of the first stack

From the table of  values, for the first and the last points, we have;

m = (52 - 28)/(5 - 1) = 24/4 = 6

Which gives;

h - 52 = 6×(n - 5)

h = 6·n - 30 + 52 = 6·n + 22

h = 6·n + 22

Where;

h = The height of stack in cm

n = The number of flower pots

Therefore, by comparing to the general form of the equation of a straight line, y = m·x + c, the y-intercept, c = 22

The simplified algebraic expression to represent the height of a stack of n flower pots is therefore given as h = 6·n + 22.

Got it right on EDGE 2022

The total money earned by Marcus in the week is $315.1875.

Given that, Marcus works at a coffee shop. He earns $10.25 each hour.

Decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point. The dot present between the whole number and fractions part is called the decimal point.

1) Number of hours =

6.15+7.15+6+6.45+5 =30.75

2) Money earned in the week

= 30.75×10.25

= $315.1875

Therefore, the total money earned by Marcus in the week is $315.1875.

Answer: -22, -28 -34

Step-by-step explanation:

Subtract 6 from every number

Answer:

We subtract 6 each time

-22,-28,-34

Step-by-step explanation:

8,2,-4,-10,-16

8-2 = 6

We subtract 6 each time

2-6 = -4

-4-6 = -10

So it is verified

-16-6 = -22

-22-6 = -28

-28-6 = -34

Step-by-step explanation:

Answer:X + Y ≥ 4

$2.20X + $2.95Y ≤ $10.00

Strawberries cost $2.20 per pound

Raspberries cost $2.95 per pound

Jada only has $10.00 to spend

She wants to buy at least 4 pounds

Assumption: She buys X pounds of strawberries and Y pounds of raspberries.

Solution:

Number of pounds can't be less than 4

i.e X + Y ≥ 4

The cost of buying strawberries and raspberries has to be $10.00 or less than $10.00

i.e $2.20X + $2.95Y ≤ $10.00

So the system of equations is;

X + Y ≥ 4

$2.20X + $2.95Y ≤ $10.00

B. Point B

Answer:

a- (x-7)(x+9) | b- 193*207 | c- 242*258

Step-by-step explanation:

a)

x^2+2x-63.

the middle number is 2 and the last number is -63.

You would have 2 numbers that add to 2 and multiply to -63.

Those numbers are -7 and 9.

so (x-7)(x+9).

b)

((200)-7)((200)+9)

(193)(209).

You can check this by multiplying 193 by 209 and then doing (200)^2+2(200)-63. Both would equal 40337.

c)

2(x-7)+2(x+9)=1000

(2x-14)+(2x+18)=1000

4x+4=1000

4x=996

x=249.

((249)-7)((249)+9)

(242)(258)

Answer:

10x

Step-by-step explanation:

Since 4x and 6x are like terms you add the numbers as normal then put the x behind it. So it would be 4 + 6 = 10. Now add the x. 10x

6 days ; 2300 calories

Step-by-step explanation:

Given the following :

Current consumption :

Simba = 1520 calories per day

Increases by 130 calories per day : After d days ;

S(d) = 1520 + 130d

Where ; d = number of days

Cuddle = 3380 calories

Decreases by 180 calories each day; after d days ;

S(d) = 3380 - 180d

Pattern continues until they both consume same number of calories each day

S(d) = C(d)

1520 + 130d = 3380 - 180d

130d + 180d = 3380 - 1520

310d = 1860

d = 6

Number of calories they will be consuming them ;

Using : S(d) = 3380 - 180d

S(6) = 3380 - 180(6)

S = 3380 - 1080

S = 2300

They will be consuming 2300 calories by then.

Answer:

If she is 120 feet below the surface she is -120 feet below the surface. If she goes up by 83 feet she will be 37 feet below the surface. Therfore the answer is -37 feet.

The current dept is 37 feet below the water surface.

A negative sign or minus sign is a mathematical symbol to represents the subtraction between to numbers. It is also used to represent a negative numbers.

The negative or minus sign also indicates movement in the opposite direction on a number line.

According to the given question

Scuba diver is 120 feet below the water surface.

On number line 120 feet below is  represented by -120.

She ascends 83 feet means , she goes up 83 feet up

So, the current depth is calculated as

-120feet + 83feet

= -37 feet.

The negative sign represent that Scuba is 37 feet below the water surface.

Hence, the current dept is 37 feet below the water surface.

Answer:

Pat's score is 1.67 standard deviation above the mean

Step-by-step explanation:

We solve using z score formula

z score tells us how much a score deviates from the mean

The formula for calculating a z-score is is z = (x-μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation.

x = 83

μ = 75

σ = 4.8

z score = 1.66667

Therefore, Pat's score is 1.67 standard deviations above the mean
