Answer:
[tex]2360m^2[/tex] of sheet steel are needed
Step-by-step explanation:
Given
The missing dimensions are:
[tex]Length = 5m[/tex]
[tex]Width = 6m[/tex]
[tex]Height = 8m[/tex]
[tex]n=10[/tex] --- number of containers
Required
The surface area of all containers
First, we calculate the surface area (A) of 1 container
[tex]A=2*(Length * Width + Length * Height + Width * Height)[/tex]
[tex]A=2*(5m* 6m+ 5m* 8m+ 6m * 8m)[/tex]
[tex]A=2*(30m^2 + 40m^2 + 48m^2)[/tex]
[tex]A=2*(118m^2)[/tex]
[tex]A=236m^2[/tex]
The surface area of 10 is:
[tex]Area = 10 * A[/tex]
[tex]Area = 10 * 236m^2[/tex]
[tex]Area = 2360m^2[/tex]

Christine(C) and two of her friends. Bianca B) and Travis(7), won first place for a marketing case competition. They received an amount of $3,600, however,
they decided to share the prize in the ratio of the amount of time each of them spent on the marketing case. If Christine spent 4 hours, Bianca spent 6 hours.
and Travis spent 8 hours, what would be each person's share of the prize?

c
C:800.B:1200.T:1600
Answer: C:800.B:1200.T:1600
Step-by-step explanation: If the ratio is proportional to the time spent on the marketing competition, then we can add the hours up: 4+6+8=18. Total amount divded by total hours -> 3600/18=200. So each hour worked is 200 dollars. Christine worked 4 hours, 4*200=800, Bianca worked 6 hours, 6*200=1,200, and Travis worked 8 hours, 8*200=1,600.
Someone pls help…. We need to find m angle f
Answer:
m<F = 95°
Step-by-step explanation:
We'll begin by calculating the value of x. This can be obtained as follow:
m<C = 50
m<A = (10x – 5)
m<B = m<G = (2x + 15)
m<C + m<A + m<B = 180 (Sum of angles in a triangle)
50 + (10x – 5) + (2x + 15) = 180
50 + 10x – 5 + 2x + 15 = 180
50 – 5 + 15 + 10x + 2x = 180
60 + 12x = 180
Collect like terms
12x = 180 – 60
12x = 120
Divide both side by 12
x = 120 / 12
x = 10
Finally, we shall determine the value of m<F. This can be obtained as follow:
m<F = m<A
But
m<A = 10x – 5
x = 10
Therefore,
m<F = 10x – 5
m<F = 10(10) – 5
m<F = 100 – 5
m<F = 95°

The formula for the area of a parallelogram is A = bh, where b is the base and h is the height.
A parallelogram that is not drawn to scale. The height is labeled (x minus 4) centimeters. The base is labeled (2 x squared + 2 x minus 6) centimeters.
Which simplified expression represents the area of the parallelogram?
Answer:
Area = 2x^3 - 6x^2 - 14x + 24
Step-by-step explanation:
h = x - 4
b = 2x^2 + 2x - 6
Area = b * h
Area = (x - 4)(2x^2 + 2x - 6) Multiply through by x
Area = 2x^3 + 2x^2 - 6x - 8x^2 - 8x + 24 Multiply through by -4
Area = 2x^3 + (2x^2 - 8x^2) - 6x - 8x + 24 Collect like terms.
Answer
Area = 2x^3 - 6x^2 - 14x + 24

Answer:
Total cost = $6.61
Step-by-step explanation:
Given the following data;
Cost of breaded chicken = $5.68/lb
Quantity of breaded chicken = ¼
Baked chicken = $6.92/lb
Quantity of baked chicken = ¾
To find the total cost;
First of all, we would determine the cost of breaded chicken and baked chicken.
Cost of breaded chicken = ¼ * 5.68
Cost of breaded chicken = $1.42
Cost of baked chicken = ¾ * 6.92
Cost of baked chicken = 20.76/4
Cost of baked chicken = $5.19
Total cost = Cost of breaded chicken + Cost of baked chicken
Total cost = 1.42 + 5.19
Total cost = $6.61

Answer:
[tex]{\text{C. }y=5x+29[/tex]
Step-by-step explanation:
The slope-intercept form of a line is given by [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope of the line and [tex]b[/tex] is the y-intercept.
The slopes of parallel lines are always equal. Therefore, the slope of the equation we want to find will also be [tex]5[/tex]. The equation of the line must be true for any point it passes through. Thus, we can plug in the point [tex](-6,-1)[/tex] to solve:

When a triangle is inscribed in a semicircle where a diameter of the circle is a side of the triangle, the triangle formed is always a right triangle. If an isosceles triangle (two equal sides) is inscribed in a semicircle with a radius of 9 inches, find the length of the two legs of the triangle.
Answer:
Step-by-step explanation:
diameter = 18 inches
each leg = 18/√2 = 9√2 ≅ 12.7 inches
The length of the two legs of the isosceles triangle is 9√2.
What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of the angles of a triangle is always 180°
Given that,
When a triangle is inscribed in a semicircle with one side being the diameter of the circle, a right triangle is always created.
Also, the radius of semicircle is 9 inches,
Since, the isosceles triangle inscribed in the semicircle.
Sides of an isosceles triangle are equal, therefore the corresponding angle will also equal.
The sum of all three angles of a triangle is 180°
x+x+90 = 180
2x = 90
x=45
radius of circle is 9 inches, therefore diameter of circle = 18 inches
Apply sin rule,
18/sin90 = x/sin45
18/1 = x/1/√2
x= 9√2
The length of the side of the isosceles triangle is 9√2.

This is a rhombus. Solve for x, Then label each angle with its correct measures:
Answer:
Step-by-step explanation:
In the given rhombus, the value of x is 18.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We know that;
Diagonal bisect the angles of a rhombus.
Hence, We can formulate;
⇒ (2x + 16)° = (3x - 2)°
Solve for x as;
⇒ 2x + 16 = 3x - 2
Subtract 2x both side,
⇒ 2x + 16 - 2x = 3x - 2 - 2x
⇒ 16 = x - 2
Add 2 both side,
⇒ 16 + 2 = x - 2 + 2
⇒ 18 = x
⇒ x = 18
Thus, The value of x in rhombus = 18

A sample of 340 students in a high school were asked how many times they go to their locker each day. 137 of those surveyed said that they go to their locker at least 3 times each day. Calculate the sample proportion of students who go to their locker at least 3 times each day. Either give the exact fraction or decimal, or round to three decimal places.
Answer:
The sample proportion of students who go to their locker at least 3 times each day is 0.403.
Step-by-step explanation:
Sample proportion of students who go to their locker at least 3 times each day.
The sample proportion of students who go to their locker at least 3 times each day is the number of students who do this divided by the size of the sample.
In this question:
137 go to their locker at least 3 times each day, sample of 340 students. So
137/340 = 0.403
The sample proportion of students who go to their locker at least 3 times each day is 0.403.

According to a government study, among adults in the 25- to 34-year age group, the mean amount spent per year on reading and entertainment is $2,020. Assume that the distribution of the amounts spent follows the normal distribution with a standard deviation of $456. Use Appendix B.3. (Round your z-score computation to 2 decimal places and final answers to 2 decimal places.) What percent of the adults spend more than $2,600 per year on reading and entertainment
Answer:
z = x-u/s
z = 2600 - 2020/456
z = 1.27
= .897
1-.898 = .102
z > 1.27 = 10.2%
The percentage of adults spending more than $2,600 per year on reading and entertainment is 10.2%.
What is the z-score?The standard score in statistics is the number of standard deviations that a raw score deviates from or exceeds the mean of the phenomenon being observed or assessed. Standard scores are positive for raw scores above the mean and negative for raw scores below the mean.
Given that according to a government study, among adults in the 25- to 34-year age group, the mean amount spent per year on reading and entertainment is $2,020. Assume that the distribution of the amounts spent follows the normal distribution with a standard deviation of $456.
The percentage will be calculated as,
z = x-u/s
z = 2600 - (2020/456)
z = 1.27
The value of z=1.27 in the table is 0.897. The percentage will be calculated as,
