Hope you know how to use a graph
A(3,0) B(9,0) C(9,6)

Answer:

50 squirrels, 60 inches, A'(3,0), B'(9,0), C'(9,6)

Step-by-step explanation:

Given that the ratio of birds to squirrels is 4:5 and there are 90 altogether, define a variable [tex]x[/tex], and [tex]4x + 5x = 90[/tex], and [tex]x = 10[/tex]. Since squirrels are the [tex]5x[/tex] part, [tex]5\cdot10 = 50[/tex] squirrels.

1/5 of her total height is 12 so let's say her total height is [tex]h[/tex] and [tex]\frac{1}{5}h = 12[/tex].

Solve for [tex]h[/tex] to get 60 inches.

Translating this triangle to the right 3 units just means adding 3 to all the x coordinates of the vertices. This gives you A'(3,0), B'(9,0), C'(9,6).

3. A company makes a profit of $15 per software program and $10 per video game. The company can produce

at most 70 software programs and at most 80 video games per week. Total production cannot exceed 100

items per week. How many items of each kind should be produced per week in order to maximize the profit?

Use linear programming to solve. Show all your work.

Answers

Answer:

For the profit to be maximized, 20 software programs and 80 video games should be produced

Step-by-step explanation:

Let x represent the number of the software programs and let y represent the number of video games.

We are told that the company can produce at most 70 software programs and then, at most 80 video games per week. Thus;

x ≤ 70

y ≤ 80

Also, we are told that the overall production cannot exceed 100. Thus;

x + y ≤ 100

Since the company makes a profit of $15 per software program and $10 per video game. Then, the function to be maximized is;

15x + 10y

When they produce at most 70 software programs, it means that the number of video games that can be produced is: 100 - 70 = 30.

Thus, one point of maximizing values is; (70, 30)

Also, when they produce at most 80 video games per week, the number of software programs that can be produced is; 100 - 80 = 20.

Thus, second point of maximization is;

(20, 80)

Putting these points into the objective function, we have;

At (70, 30); 15(70) + 10(30) = $1350

At (20, 80); 15(20) + 10(80) = $1100

For the profit to be maximized, 20 software programs and 80 video games should be produced

Given the equation of a line: y = (2/3)x + 1. Select the equation of the line PARALLEL to this line

Answers

Answer:

y = (2/3)x + K, where K is any number except 1

Step-by-step explanation:

In the slope-intercept form of the linear equation, y = mx +b, the 'm' is for the slope, m = 2/3.

Any line that also has a slope of 2/3 will be parallel.

y = (2/3)x - 10       will be parallel

y = (2/3)x + 12      will be parallel

y = (2/3)x - (1/2)    will be parallel

y = (2/3)x + 5,391 will be parallel

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given,

Lincoln invested $440 in an account paying an interest rate of 7 ​% compounded continuously.

Robert invested $440 in an account paying an interest rate of 5 ​ %.

We need to find how much more money would Lincoln have in his account than Robert in 11 years.

[tex]A=Pe^{rt}[/tex]

For Lincoln:

P=440,

r=7%=0.07

t=11

A=440e⁰⁰⁷ˣ¹¹

A=440e⁰⁷⁷

A=949.96

For  Robert,

P=440,

r=5%=0.05

A=440e⁰⁰⁵ˣ¹¹

A=440e⁰⁵⁵

A=761.2

Now find the difference of Albert and Robert money

949.96-761.2

188.76

Hence, After 11 years,188.76 more money would Lincoln have in his account than Robert

Answer:

8 ft

Step-by-step explanation:

By Pythagoras Theorem

[tex]x = \sqrt{ {10}^{2} - {6}^{2} } \\ \\ x = \sqrt{100 - 36} \\ \\ x = \sqrt{64} \\ \\ x = 8 \: ft[/tex]

Answer: It's 8 :)

Step-by-step explanation: Do the Pythagorean Theorem. a^2 + b^2 = c^2. In every case, c is the hypotenuse, so you do 10^2 = 6^2 + x^2. Then, it becomes 100 = 36 + x^2, then subtract 36 and you get 64. Then, you square root both sides to get 8. Have a great day!

A truck that is 10 ft. by 12 ft. by 8 ft. carries cube shaped boxes that have a
length of 1.5 ft. How many of these boxes can this truck hold?

Answers

Answer:

284.4

Step-by-step explanation:

Divide all numbers by 1.5. example: (10)1.5(12)1.5(81.5= 284.444444 but I rounded it to 284. You're welcome

284 boxes in the shape of the cubes can be fitted in the truck.

If a truck is fitted fully with the cubes, volume of the truck will be equal to the volume of cubes to be fitted.

Dimensions of the truck given in the question,

Length = 10 feet, width = 12 feet and height = 8 feet

Since, volume of a cuboid (shape of a truck) is given by the expression,

Volume = Length × Width × Height

Therefore, volume of the truck = 10 × 12 × 8

                                                   = 960 feet³

Volume of a cube is given by the expression,

Volume = (side)³

Therefore, volume of the cube with side length 1.5 feet will be,

Volume of a cube = (1.5)³

                              = 3.375 cubic feet

Let the number of cubes fitted in the truck = x

Therefore, volume of 'x' cubes = (3.375x) feet³

Since, volume of the truck = Volume of the cubes fitted

3.375x = 960

x = [tex]\frac{960}{3.375}[/tex]

x = 284.44

x ≈ 284

     Therefore, 284 boxes in the shape of the cubes can be fitted in the truck.
