The park i 45 feet long . How long is park yard ? (1yard=3feet)
Answer:
135 yards
Step-by-step explanation:
There are 135 yards in 45 feet.
Our information:
The park is 45 feet long
There is (3 feet= 1 yard)
Since there is 3 feet in 1 yard. You have to multiply 45 x 3.
So, The answer is 135 yards.
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?
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 feetSince, 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.

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

The vertices of ∆ABC are A (0,0), B (6,0) and C (6,6). Draw the triangle and its
image ∆ A’B’C’ translated to the right 3 units. What are the coordinates of the
vertices of ∆ A’B’C’?
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.
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

integer. What are the two numbers?
Answer:
2x^2+x-36=0
(4,0)
2*4^2+4-15=21
Step-by-step explanation:
The addition is one of the four fundamental mathematical operations. The two integers are 4 and 17.
What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
Let the two unknown integers be represented by x and y, where x
Given that The sum of two integers is 21. Therefore, we can write,
x + y = 21
y = 21 - x
Also, Fifteen less than double the square of the smaller integer is equal to the larger integer.
2(x²) - 15 = y
Substitute the value of y from the first equation,
2(x²) - 15 = 21 - x
2x² - 15 = 21 - x
2x² + x - 15 - 21 = 0
2x² + x - 36 = 0
2x² + 9x - 8x - 36 = 0
x(2x + 9) -4(2x + 9) = 0
(x-4)(2x+9) = 0
x = (-9/2), 4
Since it is given that the number are integers, therefore, the only option is 4.
Further, the two integers are,
x = 4
y = 21 - x = 21 - 4 = 17
Hence, the two integers are 4 and 17.

Answer:
y < 1/4x + 6
Step-by-step explanation:
So the first thing I found was the slope so using rise over run you could see it was going down one and to the right 4 times which gave me 1/4 for the slope, then i needed to find the y intercept which was positive 6 I got I knew it was less than because it is shaded under the line and i knew it was less than opposed to less then or equal to because its a dotted line.
So to make the equation we first do y = slope (x) + y intercept
(if your y intercept was -6 you would change the + to a -)
our slope is 1/4 so y = 1/4x
our y intercept is 6 so we get y = 1/4x + 6
