find the area of the rectangular prism
Answer:
384 sq ft.
Step-by-step explanation:
Given:
L = 12 ft
W = 9 ft
H = 4 ft
Required:
Surface area of the rectangular prism
SOLUTION:
Surface Area of rectangular prism = 2(LW + LH + WH)
SA = 2(12*9 + 12*4 + 9*4)
SA = 2(108 + 48 + 36)
SA = 2(192)
SA = 384 ft²
A local store, Faith Ltd has two options to choose either Big Van or Small Van or both types of van to supply bags of rice to local restaurants.
(a) Big Van has capacity of 15 tonnes at £250
(b) Small Van has capacity of 9 tonnes at £151.
If the Faith Ltd wants to supply 50 tonnes of rice what is cheapest cost £ to pay?
Answer:
Cheapest cost to pay = £906
Step-by-step explanation:
Given that:
Rice to supply = 50 tonnes
Option A:
Big van has capacity of 15 tonnes.
Number of big vans = [tex]\frac{50}{15}=3.33[/tex]
It means that 4 big vans will be needed for transporting 50 tonnes of rice.
Cost of 4 vans = 4*250 = £1000
Option B:
Small van has capacity of 9 tonnes.
Number of small vans = [tex]\frac{50}{9} = 5.55[/tex]
It means that 6 small vans will be nedded for transporting 50 tonnes of rice.
Cost of 6 vans = 6*151 = £906
Therefore,
The company can transport the rice through small vans.
Hence,
Cheapest cost to pay = £906

You roll a number cube twice. Find the probability of the events. Rolling an odd number 2 or a 4.
Answer: see below
Step-by-step explanation:
If this is a 6 sided die then the only possible roll that isnt an odd, a 2, or a 4 is 6.
The probability of something happening is also the probability of something not happening. So in order to not roll an odd, a 2 or a 4 in two rolls, you have to roll a 6 twice.
P = 1 - (1/6)(1/6) = 1 - (1/36) = (35/36)

Suppose a city with population 500,000 has been growing at a rate of 3% per year if this continues find the population of the city in 16 years will be approximately?
Answer:
740,000
Step-by-step explanation:
500,000/100 = 5,000 ×3= 15,000
15,000×16= 240,000 increase in population
500,000+240,000= 740000
Answer:260,000
Step-by-step explanation:
500,000÷3 equal 15,000 that means it’s going every year by 15,000 times that by 16 equals 260,000

g(a)=-40

139
Answer:
We conclude that:
(hog)(2) = 59Step-by-step explanation:
Given
h(a) = a² - 5
g(a) = -4x
To determine
(hog)(2)
Using the formula
(hog)(2) = h(g(2))
First determining the g(2)
substitute x = 2 in g(a) = -4x
g(a) = -4x
g(2) = -4(2) = -8
so
(hog)(2) = h(g(2)) = h(-8)
now determining the h(-8)
substitute x = -8 in h(a) = a² - 5
h(a) = a² - 5
h(-8) = (-8)² - 5
h(-8) = 64 - 5
h(-8) = 59
so
(hog)(2) = h(g(2)) = h(-8) = 59
Therefore, we conclude that:

A 41-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third piece is one inch more than five times the length of the first piece. Find the lengths of the pieces.
Answer:
Length of first piece = 5 inches
Length of second piece = 10 inches
Length of third piece = 26 inches
Step-by-step explanation:
Given that:
Length of piece of steel = 41 inch
Let,
x be the length of first piece
y be the length of second piece
z be the length of third piece
According to given statement;
x+y+z = 41 Eqn 1
y = 2x Eqn 2
z = 5x+1 Eqn 3
Putting value of y and z from Eqn 2 and 3 in Eqn 1
[tex]x+2x+5x+1=41\\8x = 41-1 \\8x = 40[/tex]
Dividing both sides by 8
[tex]\frac{8x}{8}=\frac{40}{8}\\x=5[/tex]
Putting x=5 in Eqn 2 and 3
y = 2(5) = 10
z = 5(5) + 1 = 25+1 = 26
Hence,
Length of first piece = 5 inches
Length of second piece = 10 inches
Length of third piece = 26 inches
The parent function of a graph is f(x)=3(2)x
Samantha reflected the parent function over the x-axis to get the following function: g(x)=3(2)−x
a. Describe Samantha's error (2 points)
b. Write the correct equation for g(x) after f(x) has been reflected over the x-axis. (2 points)
Part (a)
She replaced x with -x to go from f(x) = 3(2)^x to g(x) = 3(2)^(-x). This will not reflect the graph of f(x) over the x axis. Instead, it will reflect over the y axis. This is because each input is negated from positive to negative, or vice versa. For instance the old input x = 2 becomes the new input -2. Applying this idea to every x input will mirror the curve over the vertical y axis.
==============================================
Part (b)
The correct equation should be g(x) = -3(2)^x
The negative out front is the same as -1.
We can think of it as g(x) = -1*f(x). The f(x) is the output value, or y value. If we multiply each y output by -1, this will flip every point over the horizontal x axis. A point like (0,3) moves to (0,-3) after doing this operation.

The length of a rectangle is (x - 9) feet. Its width is x feet. Write an expression you could use to find the perimeter
Answer:
The expression for the perimeter of the rectangle is: [tex]P = 4x - 18[/tex]
Step-by-step explanation:
Perimeter of a rectangle:
A rectangle has length l and width w. It's perimeter is given by:
[tex]P = 2(l + w)[/tex]
In this question:
[tex]l = x - 9, w = x[/tex]
So
[tex]P = 2(x - 9 + x) = 2(2x - 9) = 4x - 18[/tex]
The expression for the perimeter of the rectangle is: [tex]P = 4x - 18[/tex]
Explain why drawing both diagonals on any rectangle will always result in two pairs of nonoverlapping congruent triangles.
Answer:
It is because not all sides of a rectangle are equal in length; unlike a square.
Step-by-step explanation:
Let's start by drawing the first diagonal.
You know already how a rectangle looks. It has 4 sides and 2 sets of parallel sides. Each pair of parallel sides has the same length.
A diagonal is a line crossing from one edge of a four-sided shape to the opposite edge; such that it divides the shape into two equal halves.
Now place your rectangle horizontally. Let the two longer sides be on the horizon while the two shorter sides go vertical.
We draw the first diagonal from the edge on the top right to the opposite edge (down left). This will divide the shape into two equal halves and each half will be a triangle; a congruent one at that.
When you fold this rectangle along its diagonal, the two triangles will not overlap! The resulting shape will be like two triangular mountains lying side by side. You can use a paper (cut in the shape of a rectangle) for this experiment.
Why does this happen, instead of the two triangles covering each other (overlapping)?
This happens because a rectangle doesn't have 4 equal sides. Check out a square and you'll see that both triangles will overlap after a diagonal is drawn across the square.
Draw the second diagonal of the rectangle (from up-left to down-right) and the same thing is observed.

> Next question You can retry this question below What is the slope of a line that is parallel to the line – 7x - y = 2 ? Write your answer as an integer or fraction. The slope is Check Answer Type here to search O
Answer:
The slope of parallel line m = -7 is an integer
Step-by-step explanation:
Explanation:-
Given that the parallel line
-7x-y = 2
we know that the slope of the two parallel lines are equal
m₁ = m₂
The given parallel line equation
- 7 x - y = 2
The slope-intercept form
y = - 7x -2
comparing
y = mx +C
slope of parallel line m = -7 is an integer
y- Intercept c = -2
Oscar is buying 4 new tires for his car. He has $240 budgeted for the tires, but can afford to pay $35 more or less than that amount. This equation represents the situation: |4t - 240 | = 35
To keep within his budget, Oscar can pay a minimum of $____ and a maximum of $___ for each tire.
Given that the dealer sells a dozen tires for $240, every 3-tire set costs $60. There are six 2-tire sets in a dozen. Thus, his total revenue should be $360. The total profit is the difference between the total revenue and the total cost. The answer is therefore, the first choice, $120.
Answer:
min: 51.25
max: 68.75
Step-by-step explanation:
240-35=205
205/4=51.25
240+35=275
275/4=68.78

If Maersk ran a total 80 trains a day with each having 180 containers per train, how many cars would they need in total?
Answer:
Assuming 1 container per train car..
180 * 80
can be done mentally as
18 * 8 = 144
add the two zeroes onto the answer
180 * 80 = 14,400

The line has a positive slope. Let's look at all the slopes:
1) -3
2) -3
3) 3
4)3
Which ones are positive? That's right, 3 and 4. We don't know which equation would be the equation of the line. That's where the other information comes in.
The line intersects the y-axis at at a point that has a negative y-coordinate. Lets write the last two equations in slope-intercept form.
1) y = -3/2x - 5/2
2) y = -3/2x + 5/2
We have to graph both of the lines now. The graphs are at the very bottom. Take a look at them. In the first one, the y-intercept is a negative and in the second one, the y-intercept is positive.
The third one AKA 3x + 2y = -5 is the equation of the line. I hope this helps! Let me know if I got it wrong or if you need any more help.
