**One box** of oaties will be **enough** for two groups of children.

We can state the box of oaties is enough for everyone, if the amount required by number of children in each group is less than or equal to 12.

So, amount of cereal required by **younger/****o****lder** children = amount required by **one child** × number of** children**

Amount of cereal required by younger children = 1/3 × 11

Amount of cereal required by younger children = 11/3 cups of cereal

Amount of cereal required by older children = 3/4 × 10

Amount of cereal required by younger children = 15/2 cups of cereal

Amount of cereal = 12 - (11/3 + 15/2)

Taking LCM in the bracket, we get 6

Amount of cereal = 12 - (11×2 + 15×3/6)

Solving the bracket

Amount of cereal = 12 - (22 + 45/6)

Performing **addition** = 12 - (67/6)

Amount of cereal = (12×6 - 67)/6

Amount of cereal = 72 - 67/6

Performing **subtraction** in numerator

Amount of cereal = 5/6

As **5/6 cups** of cereal is remaining, thus, a box of oaties will be **enough** for 11 younger children and 10 older children.

35% = 0.35

“of” means multiplication, so multiply 0.35 • 279.99 = 97.996

Jack and Jill took a trip to Grandma’s house. It took them 8 hr to get to Grandma’s house but on their way back home they took the scenic route, which is 20 mi longer. If their speed going home was 10 mi/hr less than their speed going to Grandma’s house, and if it took them 10 hr to get home, how far did they travel going to Grandma’s and what was their average speed on the trip there?

**Answer:**

Let s be the distance to Grandma’s and v the speed they went to get to Grandma’s.

So s=8v, because it took them 8 hours to get there.

Coming back they travelled s+20 miles. Since s=8v we can write this as 8v+20 miles.

Their speed was reduced by 10mph so that’s v-10. It took them 10 hours to return so:

8v+20=10(v-10); 8v+20=10v-100; 120=2v

so v=60mph. This is their average speed going to Grandma’s.

**Answer:**

A. The total number of hours it takes to make dresses and skirts each month

**Step-by-step explanation:**

By multiplying the amount of time to make an item by the amount of items made, you get the total amount of time spent on making those items. Therefore the total time spent making dresses is 8x, and the total time spent making skirts is 3y, which means that the total time to make both is 8x+3y.

15. Write an equation that goes through point (-6, 8) and has a y-intercept of -4.

**Answer:**

y = -2x - 4

**Step-by-step explanation:**

First, substitute the known values into the slope-intercept form, y = mx + b, where m represents the slope of the line and b represents the y-coordinate of the point of intersection of the line and the y-intercept. We are given that the graph has a y-intercept of -4, so substitute -4 for b. The graph contains the point (-6, 8), so substitute -6 for x and 8 for y.

8 = -6m - 4

12 = -6m

m = -2

Finally, substitute -2 for m and -4 for b to write the equation of the line in the form, y = mx + b.

y = -2x - 4

1. Which kind of model do you think best represents the profit for each business?

2. Find a function that models the profit you can expect, based on your projections, for each business. You can round your values to the nearest thousandth, as needed.

**Answer:**

Please see below for answers and explanation and attachments

**Step-by-step explanation:**

These models are best figured out using regression analysis which is a rather complicated computation but luckily there are calculators that can solve

1. The best way to approach this problem is to plot the values and see whether the model is a linear equation or a higher degree equation.

For all three cases it appears that the equations are not linear which would have suggested a model of the form y = mx + b where y = profit in $, x = hours, m is the slope (rate of increase in profit) and b a constant, the y-intercept

For example if you look at the data for the dog walker table, the increase in $ for every additional hour of service is not constant eliminating a linear model. For the first hour, the increase is $7, the second hour it is $11, the third it is $27

So i assumed a quadratic model of the form y = ax² + bx + c where y = profit in $ and x is the number of hours of service for all three businesses

There are plenty of online calculators out there which can rapidly compute the quadratic regression model parameters fitting the data and provide a level of goodness of fit of the equation through a statistic known as the correlation coefficient, r

I entered the data for all 3 rows and came up with the following results

In all the equations, y represents the profit in $ and x the hours

I have also attached screenshots of the computation results which should be self explanatory

Dog Walker

Equation:

y = 1.05357x² + 8.3964x - 6.7

Correlation Coefficient r:

How many pounds of apples will he get if he goes to David’s orchard?

The pounds of **apples** that he get if he goes to David’s orchard is 20 pounds.

Let the assumed **amount** with him be $40.

It should be noted that for David's orchard, the first ten pounds are $2 per round and each additional round is $1 per **pound**.

Therefore, the expression to illustrate this will be:

($2 × 10) + ($1 × r)

where r = additional **pounds**

Therefore,

($2 × 10) + ($1 × r) = $40

find the circumference and area if its 56 cm

If the diameter of the circle is **56cm² **then the **circumference **of the circle is 176cm and the **area **of the circle is **2464cm²**.

A circle's area is equal to pi times the radius squared (A = πr). Discover how to apply this formula to determine a circle's area given its diameter.

Area of Circumference: What Does It Mean?The length of a circle's outline is referred to as its circumference, while the length of a form with straight sides is referred to as its perimeter. Circle circumference equals 2πr.

Low flow showerheads use 2 1/2 gallons of water per minute. If family members shower a total of 2 1/3 hours per week, how much water does the family use for showers each week? Write an expression that represents the problem. Then solve the problem

The **expression** that represents the situation is **(5/2)x = y** and the family uses **350 gallons** of water for each week.

First, we convert the given fractions into improper fractions as follows;

2 1/2 = 5/2

2 1/3 = 7/3

As the **showerhead **uses 5/2 gallons of water per minute an expression for this situation can be given as;

(5/2)x = y

Here x is the amount of time in minutes and y represents the gallons of water used by the family each week

As the family uses the showerhead for 7/3 hours per week, we first convert the hours into minutes as follows;

(7/3) × 60 = 140 minutes

Now substituting this value in the equation (5/2)x = y;

(5/2)x = y

(5/2)140 = y

y = 350 gallons

Therefore, 350 gallons of **water **is used by the family per week.

find the lcm:- x⁴+x³-x²-x, x⁴-x and 4x²-4.

The** LCM **of both the **factors** x⁴+x³-x²-x, x⁴-x and 4x²-4 is discovered to be x(x+1)²(x-1).

The LCM of any two numbers is the value that is evenly divisible by the two given numbers. Least Common Multiple is an abbreviation for Least Common** Multiples.** It's also known as the Least Common** Divisor** (LCD).

The **smallest** integer that is a multiple of two or more numbers is known as the LCM. For **instance,** the LCM of 4 and 6 is 12, and the LCM of 10 and 15 is 30.

The two given expressions are:

x⁴+x³-x²-x, x⁴-x and 4x²-4

Let us simplify both these factors.

x⁴+x³-x²-x = x(x³ + x² -x -1)

= x(x+1)(x+1)(x-1)

= x(x+1)²(x-1)

4x²- 4 = 2²(x+1)(x-1)

Multiplying each factor with the highest power,

4x²- 4 = 2²x(x+1)²(x-1)

= 4x(x+1)²(x-1)

Thus x(x+1)²(x-1) is the least common factor of both factors.

As a result, it is **discovered** that the **LCM** of x⁴+x³-x²-x, x⁴-x and 4x²-4. is x(x+1)²(x-1).
