Which of the following is the product of the rational expressions shown below

Answer:

One effect of higher food prices in a given country is higher consumer price index (CPI) inflation.However, higher food prices affect people in different economies differently.

The impact of rapidly rising food prices on CPI inflation is substantially larger in emerging market economies than advanced economies

This effect tends to be much greater for countries that are 1) large net importers of food, and 2) where households spend a greater percentage of their income on food (meaning that they have a much larger weighting of food in their CPI basket).

In short, higher food prices don't hurt everyone equally. Poorer, developing economies feel it much worse.

Step-by-step explanation:

Oil is used in the processing of many food products. In additional, oil is used in the transportation of food. As a result, with oil price increases, the price of food increases as well.

The world population continues to grow, and with that comes increased demand of various food products. As a result, this rising demand directly leads to higher prices.

The increases in food prices have already taken effect and are not likely to improve in the near future. As of February 2011, the price of wheat has increased 83% and the price of corn has doubled since one year earlier. As feed becomes more expensive, the cost of beef products is expected to increase by almost 40%, leading to much higher prices for any meat eaters out there. With unemployment remaining at very high levels, these prices will serve to further put a dent in our wallets.

The situation is even more dire in poorer countries as many of their citizens spend about 80% of their income on basic food products. As a result, food price increases can be devastating to people in these countries, with an additional 44 million people already having been pushed into poverty. The food crisis has inspired riots in countries such as Egypt, Haiti, Tunisia, and Algeria.

Answer: 25

Assuming the dotted line touches the middle of the base of the triangle,

Using Pythagoras Theorem,

(30/2)^2 + (20)^2 = x^2

x^2 = (15)^2 + 400

x^2 = 625

x = √625 or -(√625)

x = 25 or -25

But since x needs to be a positive value,

x = 25

Answer:

x = 25 cm

Step-by-step explanation:

Given the triangle is isosceles ( 2 equal sides )

Then the line from the vertex is a perpendicular bisector of the base

We can use Pythagoras' identity on the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

where x is the hypotenuse and the legs are 15 and 20, so

x² = 15² + 20² = 225 + 400 = 625

Take the square root of both sides

x = [tex]\sqrt{625}[/tex] = 25

[tex]y-4=71(x-(-2))\\\\\bold{y-4=71(x+2)}[/tex]

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

Convert:

[tex]y-4=71(x+2)[/tex]         use the distributive property

[tex]y-4=71x+142[/tex]         add 4 to both sides

[tex]\bold{y=71x+146}[/tex]

The standard form of an equation of a line:

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

[tex]\rm Speed = \dfrac{Distance}{Time}[/tex]

Susan plans on visiting her friend in the next state the distance to her friend is 1497 miles.

If she leaves on Friday and drives 8 hours at a time at 60 mph. Then the number of days, she will be there.

The distance she covers in a day will be

D = 60 × 8

D = 480 miles

Then the number of the days will be

→ 1497 / 480

→ 3.11875

→ 3 days and 1 hour.

Answer:

Second point (-5/2, -7/2)

First point (3/2, 17/2)

Step-by-step explanation:

We have two equations, and we want to know at wich poin are equal. Hence, we have a system of equations and the solution is nothing more that the point (x,y) where those functions intercepts.

4x2+ 7x -11=y

3x+4=y

Lets use substitute method

4x2+7x-11=3x+4

This can be re arrange as the following eq:

4x2+4x-15=0

A quadratic equation, its solution can be obtained using the below eq.

[tex]x=\frac{-b+/- \sqrt{x^{2}-4ac } }{2a}[/tex]

where a=4, b=4, c=-15.

Remember, the quadratic equation as a +/- sign, meaning that you will obtain one answer using the + operator and other using the - operator.

By doing the above, we have x=-5/2 and x=3/2

By using x=3/2 in equation of line (3x+4=y)  we have y=17/2

First point (3/2, 17/2)

By using x=-5/2 in equation of line (3x+4=y) we have y= -7/2

Second point (-5/2, -7/2)

Those points are the ones where the line and the parabola intercept.

Answer:

3 more trays

Step-by-step explanation:

At 35 cookies per tray, x trays is sufficient for an output of 840 cookies.  Dividing 840 cookies by 35 cookies/tray, we get  24  trays.

But Ms. Sharp already has 21 trays.

Thus, she needs 3 more to be able to bake 840 cookies.

Ms Sharp will need to bake 3 more trays of cookies to meet the requirement of 840 cookies.

To determine how many more trays of cookies Ms. Sharp needs to bake, we first calculate the total number of cookies she has already baked. She baked 21 trays with 35 cookies on each tray:

[tex]\[21 \text{ trays} \times 35 \text{ cookies per tray} = 735 \text{ cookies}\][/tex]

Ms. Sharp needs a total of 840 cookies. Therefore, we need to find out how many more cookies are required:

[tex]\[840 \text{ cookies} - 735 \text{ cookies} = 105 \text{ cookies}\][/tex]

Each tray contains 35 cookies, so we need to determine how many more trays are required to bake 105 cookies:

[tex]\[\frac{105 \text{ cookies}}{35 \text{ cookies per tray}} = 3 \text{ trays}\][/tex]

Therefore, Ms. Sharp will need to bake an additional:

[tex]\[\boxed{3}\][/tex] trays of cookies.

The domain is an empty set

EXPLANATION

The given functions are:

[tex]f(x) = \sqrt{x - 3} [/tex]

and

[tex]g(x) =1 - {x}^{2}[/tex]

[tex](f \circ \: g)(x) = f(g(x))[/tex]

[tex](f \circ \: g)(x) = f(1 - {x}^{2} )[/tex]

[tex](f \circ \: g)(x) = \sqrt{(1 - {x}^{2} ) - 3} [/tex]

[tex](f \circ \: g)(x) = \sqrt{ - {x}^{2} - 2} [/tex]

This function is defined if and only if

[tex] - {x}^{2} - 2 \geqslant 0[/tex]

[tex] {x}^{2} + 2 \leqslant 0[/tex]

There is no real values that satisfies this inequality, because

[tex] {x}^{2} + 2[/tex]

is always positive.

The domain of this composite function is a null set.

Answer:

The domain of f, and thus the range of g, is restricted to values greater than or equal to 3.

If 1 minus x squared is greater than or equal to 3, then x squared must be less than –2.

Since x squared cannot be less than a negative number, the function is undefined for all values of x.

Answer:The decimal 4.39 equals 439%

To convert from decimal to percent, just multiply the decimal value by 100. In this example we have: 4.39 × 100 = 439% (answer).

The ease way:

1) Move the decimal point two places to the right: 4.39 → 43.9 → 439.

2) Add a % sign: 439%

Answer: 439%

The equivalent value of the percentage is A = ( 4.39/100 ) = 4.39 %

Given data ,

Let the percentage be represented as A

Now , the value of A is

Let the numerator of the fraction be p

where the value of p = 4.39

Let the denominator of the fraction be q

where q = 100

Now , the fraction is A = p/q

On simplifying the expression , we get

So , the left hand side of the equation is equated to the right hand side by the value of p/q

A = 4.39/100

A = 0.0439

On further simplification , we get

A = 0.0439 = 4.39 %

So , the percentage is 4.39 %

Therefore , the value of A = 4.39 %

Hence , the expression is A = 4.39 %

Answer:

Amount invested at 8% = $2800

Amount invested at 5.5% = $2200.

Step-by-step explanation:

Let the amount invested at 8% = x

Then the amount invested at 5.5% = 5000-x

Then we get equation:

[8% of x] + [5.5% of (5000-x)] = [6.9% of 5000]

8(x) + 5.5(5000-x) = 6.9(5000)

8x + 27500 - 5.5x = 34500

8x - 5.5x = 34500-27500

2.5x = 34500-27500

2.5x = 7000

x = 7000/2.5

x = 2800

then  the amount invested at 5.5% = 5000-x = 5000-2800 = 2200

Hence final answer is given by:

Amount invested at 8% = $2800

Amount invested at 5.5% = $2200.

Final answer:

To find the amounts of sales that will meet Liz's goal, we can set up an inequality using her salary and commission. Liz needs to earn at least $2,700 this month, and with her salary and commission, we can create the inequality $2,500 + 0.06x ≥ $2,700. Solving this inequality gives us x ≥ $3,333.33. Therefore, the amounts of sales that will meet Liz's goal are any values of x that are greater than or equal to $3,333.33.

Explanation:

To find the amounts of sales that will meet Liz's goal of earning at least $2,700 this month, we can set up an inequality. Let's represent the amount of sales as 'x'.

Liz's salary is $2,500 per month, and her commission is 6% of her sales. So her total earnings for the month can be calculated as:

Total Earnings = Salary + Commission

Total Earnings = $2,500 + 0.06x (since the commission is 6% of sales)

We want Liz to earn at least $2,700, so we can set up the following inequality:

$2,500 + 0.06x ≥ $2,700

To solve this inequality, we can subtract $2,500 from both sides:

0.06x ≥ $2,700 - $2,500

0.06x ≥ $200

Finally, we divide both sides by 0.06 to isolate 'x', the amount of sales:

x ≥ $200 ÷ 0.06

x ≥ $3,333.33

Therefore, the amounts of sales that will meet Liz's goal are any values of 'x' that are greater than or equal to $3,333.33.

Step-by-step explanation:

In this question, it is asked if 5 is equal to, less than or greater than the square root of 18. So we first need to find out the value of square root 18. We can do it manually or with a scientific calculator. If we do it with a calculator, we would come to know that the answer of square root 18 is 4. 24264068. Now we would compare it with 5. We will have to see if 5 is equal to, less than or greater than this value of square root of 18. So it is clear from the above answer of square root 18, that it is less than 5.

So the answer is C, that shows that 5 is greater than square root of 18, i-e 4.24264068.
