Answer:

A rational number is a number that can be made by dividing two integers (an integer is a number with no fractional part).  The word rational includes the word "ratio." Rational numbers are basically numbers, either positive or negative that you get by dividing 2 numbers. Any number is a rational number, even fractions and decimals, except pi due to the fact that it's a irrational number.

Step-by-step explanation:

Examples of rational numbers include, 1, which you get by dividing 1 by 1, 2 which you get by dividing 2 by 1 and 2.12, which you get by dividing 212 by 100.

Hello,

Looking at the data, you should go with the second and fourth results.

On the second one, Dr. Appiah's M.A.D. is only 9.7 which is less than Dr. Singh's M.A.D. of 14.1

On the fourth one, Dr. Cantwell and Dr. Singh both have a M.A.D. that is only 0.1 from 14, so their ages vary by about the same amount.

Best of luck,

Find g(x), where g(x) is the translation 7 units up of f(x)=x2.
AfilCa [17]

Answer:

g(x)=x^2+7

g(x) in the form a(x-h)^2+k would be:

g(x)=(x-0)^2+7

Step-by-step explanation:

Given:

Parent function:

f(x)=x^2

Translation occurs 7 units up to get g(x)

Translation Rules:

f(x)\rightarrow f(x)+c

If c>0 the function shifts c units to the up.

If c the function shifts c units to the down.

So, from the above rules g(x) can be represented as:

g(x)=f(x)+7     [7 units up]

g(x)=x^2+7

Writing g(x) in the form a(x-h)^2+k where a, h, and\ k are integers.

g(x)=1(x-0)^2+7

g(x)=(x-0)^2+7

Giselle works as a carpenter and as a blacksmith.
seropon [69]

Step-by-step explanation:

$20/hr carpenter pay

$25/hr blacksmith pay

Let c = hours working carpentry

Let b = hours working as blacksmith

c + b = 30 {equation 1}

20c + 25b = 690 {equation 2}

In equation 1 solve for one variable in terms of the other.

c = 30-b

Substitute that into equation 2:

20(30-b) + 25b = 690

600 - 20b + 25b = 690

5b = 90

b = 90/5

b = 18 hours working as a blacksmith

c = 30-b = 30-18 = 12 hours as a carpenter

A freight company has shipping orders for two products. The first product has a unit volume of 10 cu ft and weighs 50 lb. The se
nydimaria [60]

Answer:

Number of units of first product = 112

Number of units of second product = 400

Step-by-step explanation:

Given that there are two products which are to be shipped.

<em>First product details:</em>

Unit volume = 10 cu ft

Weight of one unit = 50 lb

<em>Second product details:</em>

Unit volume = 3 cu ft

Weight of one unit = 40 lb

Total volume that can be carried by a truck = 2320 cu ft

Total weight that can be carried by a truck = 21600 cu ft

To find:

The number of units of each product that can be transported in one shipment in the truck?

Solution:

Let number of units of first product = x

Let number of units of second product = y

We can write down two linear equations in two variables here and solving them will give us the answer we are required to find.

As per question statement, the equations can be written as:

10x+3y = 2320 ...... (1)\\50x+40y = 21600\\\Rightarrow  5x+4y = 2160...... (2)

Multiplying equation (2) with 2 and subtracting equation (1) from it:

8y - 3y = 4320-2320\\\Rightarrow 5y = 2000\\\Rightarrow \bold{ y = 400}

By equation (1):

10x+1200 = 2320\\\Rightarrow 10x = 1120\\\Rightarrow \bold{x = 112}

Answer is:

Number of units of first product = 112

Number of units of second product = 400
