Answer:
A. Area total= 30 m2
B. 14 boxes
C. 596.40
D. 477.12
Step-by-step explanation:
A, 3.2 (1.5) A=4.8 A=6(4.2)= 30m2
B= 30/2.5= 13.95= 14 boxes
C. 12(42.6)= 596.40
D= 80/100= x/596.4 = 477.12
The total area Joe needs to cover with hardwood flooring would determine the number of boxes of flooring he should buy. Assuming the area is 100 square meters, Joe would need 49 boxes, which would cost $2,685.20 without a discount, and $2,148.16 after a 20% discount.
To determine the total area that Joe needs to floor and the number of boxes of flooring he should buy, we need to calculate the square meters of the combined living room and hallway. Unfortunately, the floor plan measurements are not provided in the question, so let's assume we have those measurements. For example, if the living room and hallway together are 100 square meters, Joe will divide the total area by the area covered by one box of flooring to find out how many boxes he needs.
The calculation for the number of boxes is as follows: total area divided by area per box. If each box contains 2.05 square meters of flooring, and the total area is 100 square meters, Joe would need 48.78 boxes. Since he can't buy a fraction of a box, he would need to purchase 49 boxes.
To find the total cost, we multiply the number of boxes by the cost per box. At $54.80 per box, the cost for 49 boxes is $2,685.20. With a 20 percent discount, the new cost is 80 percent of the original cost, which would be $2,148.16 (0.80 x 2,685.20).
A spinner is divided into four colored sections that are not of equal size: red blue purple and orange Orange : 9 red 15 blue 24 purple 12 based on these results what is the probability that the arrow will land on the purple section
Final answer:
The probability that the arrow will land on the purple section of the spinner is calculated by dividing the number of purple results (12) by the total number of results (60), resulting in a probability of 1/5 or 20%.
Explanation:
The question is asking about the probability of the arrow landing on the purple section of a spinner with four different colored sections (orange, red, blue, and purple), each with a different number of results (orange: 9, red: 15, blue: 24, purple: 12). To calculate this probability, you need to use the basic probability formula which is:
Probability of an event = (Number of ways the event can occur) / (Total number of possible outcomes)
So the probability that the arrow will land on the purple section is:
Probability of purple = Number of purple results / Total results = 12 / (9 + 15 + 24 + 12) = 12 / 60 = 1 / 5
Therefore, the probability is 0.2, or 20%.
The graph of the function f is shown. If f(x) = 4 then x could equal
A:0
B:4
C:5
D: 7
Answer: 7
Step-by-step explanation:
The question pertains to finding the x value for a given output on a graph of a function. The x value corresponds to the point where the y value is 4 on the graph.
Explanation:The subject matter in this question pertains to the interpretation of a graphical representation of a function, specifically determining the input, or x value, for a given output, y value (f(x) = 4) in this case. Without the actual graph, it's impossible to definitively identify the correct x value. However, the process involves locating the point on the graph where the y-value is 4 and then identifying the corresponding x value.
For example, if the graph is a line that passes through the point (0,4), then x would equal 0. If the graph passes through the point (4,4), then x could equal 4. Similarly, if the line goes through (5,4) or (7,4), then x could equal 5 or 7 respectively.

Combine like terms to simplify the expression below. 14x - (2x + y)
NEED THIS ASAP & STEP BY STEP!!!!
Answer:
12x - y
Step-by-step explanation:
The numbers in the brackets are being multiplied by -1. For this you can just use the opposite signs for the things in brackets and remove the brackets. (AKA 14x - 2x - y)
Then you can ignore the y for now, and just deal with the x's first.
14x - 2x = 12x
Since there's only 1 y, you don't need to do anything with it other than put it back in the equation.
The finished equation is 12x - y

number of the day can be repeated. There are 180 days in the school year. Predict how many days the
number of the day will be greater than 25.
The number of days in which a number chosen is greater than 25 is
Answer:
135 days
Step-by-step explanation:
There are 100 numbers
There are 75 numbers greater than 25 (26-100)
P(number greater than 25) =
= number of numbers greater than 100/ total outcomes
= 75/100
=3/4
There are 180 days, so multiply the number of days by the probability
3/4*180 =135
Answer:
135 of the random selections would be numbers greater than 25.
Step-by-step explanation:
Since 25 is 25% of 100, that means that 75% of the random selections would be over 25.
75% = 0.75
180*0.75 = 135
135 of the random selections would be numbers greater than 25.
In the figure, angle ABC = 2x-65° and reflex angle AOC = 3x. Find x.
Answer:
x = 70
Step-by-step explanation:
The measure arc AC is twice as angle B
The center angle that sees arc is equal to the arc it sees
<B = 2x - 65 so the measure of arc AC is 4x - 130 since this is gonna complete 3x to 360°
4x - 130 + 3x = 360°

I don't know how you are supposed to do it?
Answer:
[tex]35 {z}^{6} {d}^{11} [/tex]
Step-by-step explanation:
Assuming you are supposed to simplify:
[tex]7 {z}^{2} \times 5 {z}^{4} \times {d}^{3} \times {d}^{8} [/tex]
Then we need to apply the product rule of indices.
[tex] {a}^{m} \times {a}^{n} = {a}^{m + n} [/tex]
So we multiply to get:
[tex]35 {z}^{2 + 4} \times {d}^{3 + 8} [/tex]
We now simplify the exponents to get:
[tex]35 {z}^{6} \times {d}^{11} [/tex]
Therefore the required product is

Design your own fruit punch recipe for brunch! Your recipe must create
exactly 5 liters of punch and include at least three of the juices. Also be sure
to include how many containers of each juice you need. Show your work by
writing equations that show how you determined the capacity.
Answer:
Step-by-step explanation:
So, we know that 5000 milliliters = 5 liters right? So we have to add up the right juices in order to get 5000 milliliters.
Lemonade
4 containers.
Pineapple.
4 containers.
Grape juice.
6 containers.
Now we're gonna multiply them by their containers.
Lemonade.
250*4 = 1,000
Pineapple.
500*4 = 2,000
Grape juice.
250* 6 = 2,000
Now we add them up :)
1,000 milliliters + 2,000 milliliters + 2,000 milliliters = 5 liters.
Ps. I had this question on my test and got a good grade so ik what i'm doing.
The correct answer is: 800 milliliters + 800 milliliters + 2400 milliliters = 5000 milliliters.
By taking;
the volume of each juice container is 400 milliliters.
Since we know that 5000 milliliters = 5 liter
So we have to add up the right juices in order to get 5000 milliliters.
let the volume of each juice container is 400 milliliters.
Mango 2 containers=2×400=800 milliliters.
Pineapple 2 containers= 2×400=800 milliliters.
Orange juice 6 containers=6×400=2400 milliliters.
Now on adding them;
800 milliliters + 800 milliliters + 2400 milliliters = 5000 milliliters.
In equation form;
Let the volume of all containers are equal i.e 'x'
∴ 2×x+2×x+6×x=5000

The most likely indication of an association between gender and favorite meal to cook is if C) the value of B is not similar to the value of C, suggesting a significant difference in meal preferences among males for lunch and dinner.
To determine if there is an association between gender and a person's favorite meal to cook, we need to compare the conditional relative frequencies.
The value of A is similar to the value of B means that the percentage of males who prefer cooking breakfast is similar to the percentage of males who prefer cooking lunch. If these values are similar, it suggests that the meal preference might not be strongly associated with gender.The value of A is similar to the value of E implies that the percentage of males and females who prefer cooking breakfast are similar. This would suggest a possible lack of association as well.The value of B is not similar to the value of C means that a significant difference exists between males preferring lunch and males preferring dinner. This variation could indicate a potential association between gender and meal preference.The value of B is not similar to the value of F implies a difference between males preferring lunch and females preferring lunch. A difference here would suggest an association between gender and the preference for lunch.Since we are looking for an indication of association, the most likely scenario would be that c) the value of B is not similar to the value of C.

39) Ben builds a fence around a
rectangular garden. The perimeter of
the garden is 64 ft. The width is 12 ft
less than the length. Find the width
of the garden.
The width of the garden is 10 feet, if the perimeter of the garden is 64 feet and the width of the garden is 12 feet less than the length.
Step-by-step explanation:
The given is,
Shape of garden is rectangular
Perimeter of garden - 64 feet
Width of the garden is 12 feet less than the length.
Step: 1
Formula to calculate the perimeter of the rectangle,
[tex]P = 2(l+w)[/tex]........................(1)
Where, l - Length of rectangle
w - Width of rectangle
Step: 2
From the given data,
Let, x = Length of the garden
P = 64 feet
w = x - 12 feet
Equation (1) becomes,
64 = 2 ( x + (x - 12) )
[tex]\frac{64}{2}[/tex] = ( x + x - 12 )
32 = ( 2x - 12 )
32 + 12 = 2x
44 = 2x
[tex]x = \frac{44}{2}[/tex]
l = x = 22 feet
width, w = x - 12 = 22 - 12
w = 10 feet
Step: 3
Check for solution,
64 = 2 ( 12 + 22 )
= 2 (32)
64 = 64
Result:
The width of the garden is 10 feet, if the perimeter of the garden is 64 feet and the width of the garden is 12 feet less than the length.
The volume of the triangular pyramid is 110 cubic centimeters. The base of the triangle is
10cm and the height of the triangle is 6cm. Find the height of the pyramid.
The height of the pyramid is 11 cm
Step-by-step explanation:
Let the height of the pyramid be 'h'
Volume of the triangular pyramid= (1/3) (base area) (height of the pyramid)
110 = (1/3) (1/2) (10) (6) (h)
110 = (1/6) (60) (h)
110 = (10) h
h = 110/10
h = 11 cm
The height of the pyramid is 11cm

Please help
Answer:
x = 4
Step-by-step explanation:
Assuming these are similar triangles,we can use ratios to solve
3x+8 25
---------- = ------
4 5
Using cross products
5(3x+8) = 4*25
Distribute
15x +40 = 100
Subtract 40 from each side
15x+40-40 = 100-40
15x= 60
Divide each side by 15
15x/15 = 60/15
x =4
First, find the scale factor between both triangles.
25 / 5 = 5
15 / 3 = 5
Second, multiply to find the missing side length.
4 * 5 = 20
Third, solve for x.
3x + 8 = 20
3x + 8 - 8 = 20 - 8
3x = 12
3x/3 = 12/3
x = 4

diameter of the can is 3 inches, find the height of the can.
Given: r=1.5
Given: 51.84=2pi(1.5)(h)+2pi(1.5squared)
Answer:
The height of the can is 4 inches.
Step-by-step explanation:
Cylinder:
It is a three dimension shape.The lateral surface area is = 2πrh, r= radius, h= height.The total surface area is= (2πrh+2πr²)=2πr(r+h)The volume is = πr²h.Given that, the surface area of the soup can is 51.84 in².
The diameter of the can is 3 inches.
Then, radius of the can [tex]=\frac{Radius}{2}[/tex]
[tex]=\frac32[/tex] inches
=1.5 inches
Total surface area of the cone is = 2πrh+2πr²
[tex]=2\pi (1.5)h+2\pi (1.5)^2[/tex] in².
[tex]=2\pi (1.5)(h+1.5)[/tex] in².
=3π(h+1.5) in².
So,
3π(h+1.5)=51.84
[tex]\Rightarrow (h+1.5)=\frac{51.84}{3\pi}[/tex]
[tex]\Rightarrow h=\frac{51.84}{3\pi}-1.5[/tex]
⇒h=5.5-1.5
⇒h=4 inches
The height of the can is 4 inches.

Choose one type of power plant. Describe how electricity
is generated at this type of plant.
Answer:
Let's us talk about the Hydro Power Plant that generates electricity by energy possessed in a mass of flowing water by virtue of it height.
Step-by-step explanation:
The hydo power plant utilizes
an hydraulic turbine which converts the energy of flowing water into mechanical energy of it rotating shaft . A hydroelectric generator (alternator) converts this mechanical energy into electricity. The operation of this alternator is based on the principles of Electro magnetic induction, that when a coil of conductor is moved past a magnetic field, it causes electricity generation. So when high energy water impinges on the blade of a turbine the energy is transformed to rotational motion of the shaft which is connected to the the alternator
When the alternator turns, coils attached to it move past the magnetic field hence this causes electricity to flow and a voltage to develop at the generator output terminals."
Answer:
Sample Response: Power plants generate electricity by turning a turbine. The turbine spins a generator, which produces electricity. Fossil fuels are burned to heat water, producing steam that turns the turbine. Nuclear power plants use fission to produce the thermal energy needed to produce steam. Wind and falling water are also used to turn turbines, which spin generators that produce electricity.
