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.

Answer:

Step-by-step explanation:
Answer:
1.)
A.) The graph does represent a proportional relationship because if you calculate the slope, it's 2/3, which is consistent throughout the line and with the given points.
Slope calculation:
[tex]\frac{y2-y1}{x2-x1} \\\\\frac{6-4}{9-6} \\\\\frac{2}{3}[/tex]
B.) The coordinate (0,0) represents that no laps have been completed nor has the time started
C.) The coordinate I chose is (6,4). It represents that 4 laps were completed in 6 minutes
2.) The values to represent a proportional relationship because once calculating the slope, which is 13, you can try it with other points. Even though there's some values missing between (6,78) and (10,130), the slope remains the same.
Slope Calculation:
[tex]\frac{y2-y1}{x2-x1} \\\\\frac{130-39}{10-3} \\\\\frac{91}{7} \\\\\frac{13}{1}[/tex]
3.)
A.) The constant of proportionality is 7/4 or 1.75
B.) y = 7/4x
4.) She'll run 8 miles because since 3/4 of an hour equates to 6 miles and there's 1/4 missing, 2 miles is 1/3 of 6 miles and 1/4 is 1/3 of 3/4 , so 1/4+1/4+1/4 = 3/4. She can run 8 miles (4*2) in 1 hour (4*1/4 hour)

The sum of two integers is 21. Fifteen less than double the square of the smaller integer is equal to the larger
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

x=
Answer:
We can fine x by using the pythagoras formula
a²+b² = c²
Which C is X
And
a= 17
b= 15
So
a² + b² = c²
(17)² + (15)² = c²
289 + 225 = c²
514 = c²
√514 = c
22.67 = c
So basically X is (22.671)

200 people got an email 37 people clicked on it how do you get 18.5%
Answer:
37/200
Step-by-step explanation:
Event/Sample Space = .185 = 18.5%
Answer:
Step-by-step explanation:
If 37 people out of 200 people opened an e-mail, you can write it as 37/200.
The number above the bar is the numerator: 37
The number below the bar is the denominator: 200
Divide the numerator by the denominator to get fraction's value:
Val = 37 ÷ 200
Val = 0.185
To calculate the percent value:
0.185 = (Calculate fraction's value.)
0.185 × 100/100 =
(0.185 × 100)/100 = (Multiply that number by 100.)
18.5/100 =
18.5%; (Add the percent sign % to it.)
So that's how you get 18.5%
