A packaging company is planning is in the planning stages of creating a box that include a three dimensional support inside the box.The box has a width of 5 feet a length of 6 feet and a height of 8 feet. How long will the diagonal support need to be
Answer:
The length of the diagonal support is 69 feet.
Step-by-step explanation:
Dimensions of the box: length = 6 feet
width = 5 feet
height = 8 feet
The diagonal support relates with the diagonal of the base and the height.
From the base of the box, let the length of its diagonal be represented by x. Applying Pythagoras theorem;
[tex]/Hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]x^{2}[/tex] = [tex]6^{2}[/tex] + [tex]5^{2}[/tex]
[tex]x^{2}[/tex] = 36 + 25
= 61
x = [tex]\sqrt{61}[/tex]
= 7.81
let the length of the diagonal support be represented by l. So that;
[tex]/Hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]l^{2}[/tex] = [tex]x^{2}[/tex] + [tex]8^{2}[/tex]
= [tex]\sqrt{61}[/tex] + 64
l = [tex]\sqrt{\sqrt{61} + 64 }[/tex]
= 61 + 8
= 69
Thus, the length of the diagonal support is 69 feet.

Colin and Brian were playing darts. Colin scored 141. Brian scored 154 more than Colin. What was their combined score?
Answer:436
Step-by-step explanation:
Since Colin scored 141 and Brian scored 154 more than Colin that would be (154+141). So Brian scored 295, so you add Brian's score and Colin's so 295+141, the total score is 436

1/2 - (3/4 - 3/8)
full answer is needing pls with steps!
Answer:
1/8
Step-by-step explanation:
First, take 3/4 and make a common denominator with 3/8. You can make 3/4 into 6/8. Now, subtract 3/8 from 6/8 which is 3/8.
Second, find the common denominator between 3/8 and 1/2. You can make 1/2 into 4/8.
Third. Now subtract 3/8 from 4/8. You get 1/8.
The answer therefore is 1/8

Answer:
-19k³ + 9k² + 17
Step-by-step explanation:
Given expression;
(-9k³ + 12k² + 9) - (10k³ + 3k² + 4k - 8)
To simplify, expand the brackets.
In the second bracket, the negative sign multiplies through;
= (-9k³ + 12k² + 9) - 10k³ - 3k² - 4k + 8
= -9k³ + 12k² + 9 - 10k³ - 3k² - 4k + 8
= -9k³ - 10k³ + 12k² - 3k²+ 9+ 8
= -19k³ + 9k² + 17

solve x^2+9=0
Answer:
x = {-3, 3}Step-by-step explanation:
Simplifying
x2 + -9 = 0
Reorder the terms:
-9 + x2 = 0
Solving
-9 + x2 = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '9' to each side of the equation.
-9 + 9 + x2 = 0 + 9
Combine like terms: -9 + 9 = 0
0 + x2 = 0 + 9
x2 = 0 + 9
Combine like terms: 0 + 9 = 9
x2 = 9
Simplifying
x2 = 9
Take the square root of each side:
x = {-3, 3}
Answer:
10^2=0
Step-by-step explanation
Because x by it self always means one it would technically be 1^2+9 which would equal 10^2=0

Identify the equation in point-slope form for the perpendicular bisector of the segment with endpoints B(6,9) and C(8,−7).
Answers are one of the following
1.y − 1 = −8(x − 7)
2.y − 7 = 8(x − 1)
3.y−1=−18(x−7)
4.y−1=18(x−7)
Answer:
[tex]y-1=\frac{1}{8}\left(x-7\right)[/tex] is the equation in point-slope form for the perpendicular bisector of the segment with endpoints B(6,9) and C(8,−7).
Step-by-step explanation:
The endpoints:
B(6,9)C(8,−7)Calculating the Midpoint M of BC:
[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
[tex]\left(x_1,\:y_1\right)=\left(6,\:9\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)[/tex]
The Midpoint M of BC [tex]=\left(\frac{8+6}{2},\:\frac{-7+9}{2}\right)[/tex]
[tex]=\left(7,\:1\right)[/tex]
Calculating the slope of BC:
[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(6,\:9\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)[/tex]
[tex]m=\frac{-7-9}{8-6}[/tex]
[tex]m=-8[/tex]
Given a line with slope [tex]m[/tex] then the slope of a
line perpendicular to it is:
[tex]m_{prependicular}=-\frac{1}{m}=-\frac{1}{-8}=\frac{1}{8}[/tex]
Equation of line using point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-1=\frac{1}{8}\left(x-7\right)[/tex]
Therefore, [tex]y-1=\frac{1}{8}\left(x-7\right)[/tex] is the equation in point-slope form for the perpendicular bisector of the segment with endpoints B(6,9) and C(8,−7).

Answer:

Step-by-step explanation:
Three sisters have ages that are consecutive odd integers. The sum of the age of the youngest and three times the age of the oldest is five less than five times the middle sister's age. (a) If x represents the age of the youngest child, then write an equation that models this scenario. (b) Determine the ages of the three sisters.
Answer:
(a) x + 3(x + 4) = 5(x + 2) - 5
(b) youngest: 7 years old
middle: 9 years old
oldest: 11 years old
Step-by-step explanation:
(a)
We know that x is the youngest child's age. Since the sisters' ages are consecutive odd integers, we know that the ages differ by 2. So, the middle sister's age is x + 2 and the oldest sister's age is x + 4.
Our equation to model the sentence "the sum of the age of the youngest and three times the age of the oldest is five less than five times the middle sister's age" would be:
x + 3 * (x + 4) = 5 * (x + 2) - 5
x + 3(x + 4) = 5(x + 2) - 5
(b)
Now, we can just solve the equation above:
x + 3(x + 4) = 5(x + 2) - 5
x + 3x + 12 = 5x + 10 - 5
4x + 12 = 5x + 5
x = 12 - 5 = 7
So, the youngest sister is 7 years old.
That means the middle sister is 7 + 2 = 9 years old, and the oldest sister is 9 + 2 = 11 years old.
The ages, then, are:
youngest: 7 years old
middle: 9 years old
oldest: 11 years old

You are Miguel Cervantes de Navas y Colon, captain in the Royal Spanish Army in Sevilla in the year 1842. Outside your barracks window is a stack of cannonballs, as shown in the illustration. On an idle afternoon you decide to calculate the number of cannonballs in the stack. What is the number of cannonballs?
In Sevilla in the year 1842, you are Miguel Cervantes de Navas y Colon, a captain in the Royal Spanish Army. The total number of cannonballs in the stack is 385.
Given that,
In Sevilla in the year 1842, you are Miguel Cervantes de Navas y Colon, a captain in the Royal Spanish Army.
A pile of cannonballs is seen outside the window of your barracks.
The total number of cannonballs can be calculated using the steps below:
The following is a general formula to determine how many cannonballs are altogether in the stack:
Total number of cannonballs is n(n+1)(2n+1)/6
where "n" represents the overall number of layers.
Change the value of "n" in the formula above.
1st layer is stack of cannonballs is 1²=1 cannonball.
2nd layer is stack of cannonballs is 2²=4 cannonballs.
3rd layer is stack of cannonballs is 3²=9 cannonballs.
last layer is stack of cannonballs is 10²=100 cannonballs.
n is 10.
Substitute in the formula
=10(10+1)(2×10+1)/6
=10×11×21/6
=385
Therefore, the total number of cannonballs in the stack is 385.
