Answer:

**Answer:**

**use f(x)=y=mx+b**

**let snow = S, time = t instead of y and x**

**S(t)=mt+b**

**The rate of inches per hour represents the slope of the graph, m.**

**The y-variable would be the amount of snow, S.**

**The x-variable would be the time, t, in hours.**

**The function has three pieces:**

**i) S(t)= 2t (slope = 2)**

**ii) S(t) = 3t (slope = 3)**

**iii) S(t) = 0.75t (slope = 0.75)**

**For the first piece, i), t=3, so the amount of snow is 6 inches.**

**For the second piece, ii) t=5, so the amount of snow is 15 inches.**

**For the third piece, iii) t=1, so the amount of snow is 0.75 inch.**

**In total, it snowed 21.75 inches.**

**total snow**

To find the total accumulation of snow during the nine-hour snowstorm, we calculate the snow accumulation for each hour and then sum them up. The total accumulation of snow from the storm is 21.75 inches.

To find the **total accumulation of snow **during the nine-hour snowstorm, we need to calculate the amount of snow that fell during each hour and then sum them up. First, we calculate the snow accumulation for each hour:

- For the first 3 hours, it snowed at a rate of 2 inches per hour, so the accumulation is 3 * 2 = 6 inches.
- For the next 5 hours, it snowed at a rate of 3 inches per hour, so the accumulation is 5 * 3 = 15 inches.
- For the final hour, it snowed at a rate of 0.75 inch per hour, so the accumulation is 1 * 0.75 = 0.75 inches.

Finally, we sum up the accumulations for each hour: 6 + 15 + 0.75 = **21.75 inches**. Therefore, the total accumulation of snow from the storm is 21.75 inches.

b. you add 6000 kilograms of water to the pool. what is the depth of the water in the pool? write your answer as a fraction. the water is about meters deep.

Answer:

1). Mass of water present= 18000 kg

2).4/3 meters deep

Step-by-step explanation:

Area of the rectangle= 6*3= 18m²

Volume of water in the pool

= Deepness of water*area of rectangle

= 1*18

= 18 m³

density of water is about 1 gram per cubic centimeter

In kg per m³= 1000 kg/me

Mass of water present= density*volume

Mass of water present= 1000*18

Mass of water present= 18000 kg

2)6000 kilograms of water is added to 18000 of

Total mass present= 6000+18000

Total mass present=24000 kg

If density= 1000kg/m³

Volume present= mass/density

Volume present= 24000/1000

Volume present= 24 m³

Area of the rectangle= 18 m²

deepness of the pool= volume/area

deepness of the pool= 24/18

deepness of the pool= 4/3 meters deep

**PAYE Stands for pay as you earned.**

**Answer:**

**The first four terms of the sequence are: {-10,-23,-62,-179}**

**Step-by-step explanation:**

Given recursive formula is:

First term = a1 = -10

The first term is already known. In order to find the next terms, we will put n=2,3,4 in the recursive formula.

Putting n=2

Putting n=3

Putting n=4

Hence,

**The first four terms of the sequence are: {-10,-23,-62,-179}**

ok hola bro graicas por los punto qui :

The caterer’s fixed **cost **and the rate per student served is $6 and $150

This method is actually called method of elimination to solve a system of linear **equations**.

We make one specific variable's coefficients of equal magnitude so that we can subtract or add the **equations** and eliminate that variable to make it easy to get the value of the other variable which will then help in getting the value of the first variable (if working in dual variable system).

If we have equations:

then, if we want to eliminate variable x, then we have to multiply equation 1 with

which will make coefficient of x in first equation as

Then adding both equation will eliminate the variable x.

Given;

Cost of 100 students= $750

Cost of 150 students= %1050

Let the fixed **cost** of caterer be x

and the cost per student be y

x+100y=750...(1)

x+150y=1050...(2)

solving the above equations;

50y=300

y=6

x=750-600=150

The fixed **cost** is $150, while the per-student cost is $6.

**Step-by-step explanation:**

the price charged for 100 students reflects the cost per student that applies to the order as a whole.

100 * 6 = $600, so the fixed cost is 750-600 = 150.

...

We can check this by substituting in the other equation.

Does 150*6 + 150 = 1050?

150*6=900

900+150 = 1050.

Yes, it does

...

We can express this relationship by the equation:

y = mx + b

where

y = total cost

m = $6 per student

x = number of students

b = fixed costs = 150

y = 6x + 150

-7 - (-9)

**Answer: The answer is 2.**

**Step-by-step explanation: If you have 2 minuses together, then that actually means a plus. -7+9 is 2.**

**Answer:**

-7-(-9) a negative and a negative makes a positive so the new question will be -7+9 which should equal -16?
