The floor plan of a factory is dilated by a factor of 4 to create a new, larger floor plan.
The area of the new floor plan is _______ times larger than the area of the original floor plan?
a. 4
b. 8
c. 16
d. 64
e. 256
Answers
The original floor could be rectangle in shape.
If we consider the length of floor to be 'L' and width of floor to be 'W',
then area of original floor = length x width = LW.
And if its dimensions are dilated by scale factor of 4 to make new floor, then new length and width would become four times of older values. So new length would be '4L' and new width would be '4W'
Now area of new floor = length x width = 4L x 4W = 16LW.
It is clear that the area of new floor is 16 times of the area of original floor.
So, option C i.e. 16 is the final answer.

56.4 and 33.6
Answers
Answer: 39.8 and 50.2
Step-by-step explanation:
Here, the triangles has the legs 2.5 ft and 3 ft.
Since, by the Pythagoras theorem,
Hypotenuses of the triangle,
[tex]=\sqrt{2.5^2+3^2}=\sqrt{6.25+9}=\sqrt{15.25}\text{ feet}[/tex]
Now, let [tex]\theta_1[/tex] and [tex]\theta_2[/tex] are the angles opposite to the sides 2.5 and 3 respectively,
Hence, by the law of sine,
[tex]\frac{sin\theta_1}{2.5}=\frac{sin\theta_2}{3}=\frac{sin90^{\circ}}{\sqrt{15.25}}[/tex]
When,
[tex]\frac{sin\theta_1}{2.5}=\frac{sin90^{\circ}}{\sqrt{15.25}}[/tex]
[tex]\implies sin\theta_1=\frac{2.5}{\sqrt{15.25}}=0.64018439966 [/tex]
[tex]\implies \theta_1=39.8055710923 \approx 39.8^{\circ}[/tex]
Similarly,
[tex]\frac{sin\theta_2}{3}=\frac{sin90^{\circ}}{\sqrt{15.25}}[/tex]
[tex]\implies sin\theta_2=\frac{3}{\sqrt{15.25}}=0.76822127959 [/tex]

Explain how to find the range of a data set. what is an advantage of using the range
Answers
To find the range you would have to but the data(numbers) in order from least to greatest, then subtract the smallest number from the largest. The disadvantage of using range is that it does not measure the spread of the majority of values in a data set it only measures the spread between highest and lowest values. As a result, other measures are required in order to give a better picture of the data spread.

For all the overlaps, 5% of the total surface area is required extra. If the cost of the cardboard is Rs.4 for 1000cm(square), Find the cost of cardboard required for supplying 250 boxes of each kind.
Answers
Explanation:
1) The statement is incomplete. The complete statement contains the information of the dimensions of both bigger and smaller cardboard boxes.
2) The dimesions of bigger cardboard boxes are 25cm * 20 cm * 5 cm
3) The dimensions of smaller cardboard boxes are 15 cm * 12 cm * 5cm
4) For bigger cardboard boxes:
length, l = 25 cm
width, w = 20 cm
height, h = 5 cm
surface of each bigger carboard box = 2 [ l*w + l*h + w*h] = 2 [25*20 + 25*5 + 20*5] cm^2 = 1450 cm^2
total surface of 250 bigger cardboard boxes = 250 * 1450 cm^2 = 3625,500 cm^2
5% of the total surface area extra = 362,500cm^2 * 5 / 100 = 18,125 cm^2
Total area for bigger cardboard boxes= 362,500 cm^2 + 18,125 cm^2 = 380,625 cm^2
5) Smaller cardboard boxes
length, l = 15 cm
width, w = 12 cm
height, h = 5 cm
surface of each smaller cardboard box = 2 [l*w + l*h + w*h] = 2 [ 15*12 + 15 * 5 + 12 * 5] cm^2 = 630 cm^2
total surface of 250 smaller cardboard boxes = 250 * 630 cm^2 = 157,500 cm^2
5 % extra = 157,500 cm^2 * 5 / 100 = 7,875 cm^2
total area for smaller cardboard boxes = 157,500 cm^2 + 7,875 cm^2 = 165,375 cm^2
6) total area of cardboard required = 380,625 cm^2 + 165,375 cm^2 = 546,000 cm^2
7) Cost of cardboard required
unit cost per area * total area = (Rs 4 / 1000cm^2) * 546,000 cm^2 = Rs 2,184.
Answer: Rs 2,184

Jack bought two sweaters for $17.99 and a pair slacks for $25.50. including a 5 1/2% tax, how much was his total purchase?
Answers
5 ½ = 5 + (1 ÷ 2) = 5 + 0,5 = 5,5%
⓶ Then, once you got rid of that fraction, I usually transform a percentage into a decimal because, again, I find it easier to work with :
5,5% = 5,5 ÷ 100 = 0,055
⓷ The next step would be to add both prices together in order to get one unique price to work with instead of two :
$17,99 + $25,50 = $43,49
⓸ Next, you need to multiply the total price you calculated at #3 by the decimal of the pourcentage that you calculated at #2 in order to find the tax amount on his purchase :
5 ½% of $43,49
↓
5,5% of $43,49
↓
0,055 × $43,49 = 2,39195
Since we are calculating money, you need to round up this number at the hundredths, wich means that you’ll end up with about $2,39 of taxes on your total purchase!
⓹ The last and final step is to add the tax amount that you just calculated in #4 to the total price you calculated at #3 in order to find the total of his purchase including the 5 ½% taxes :
$43,49 + $2,39 = $45,88
If you wanted to be a tiny bit more precise, you could have decided not to round up the tax amount in #4 and just round up the final amount ↠
$43,49 + 2,39195 = 45,88195
Wich would, in this case, given you the same exact answer which is : $45,88
But it is important to keep in mind that sometimes the answer might vary if you round up only at the end, depends on your teacher’s exigences more than anything!
→ So the final answer is that his total purchase including a 5 ½% tax is : $45,88!
I really hope this helps, if there’s anything just let me know! ☻
The total cost of purchase of Jack is $ 45.88
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The cost of two sweaters is = $ 17.99
The cost of pair of slacks is = $ 25.50
So ,
The cost of two sweaters and pair of slacks = $ 17.99 + $ 25.50
= $ 43.49
Now the equation will be ,
The tax percentage on the cost of purchase = 5 1/2 %
= 5.5 %
The cost of purchase including the tax percentage =
The cost of two sweaters and pair of slacks x tax percentage
The cost of purchase including the tax percentage = 43.49 x ( 5.5/100 )
= $ 2.39195
So the equation will be ,
The total cost of purchase =
The cost of two sweaters and pair of slacks + cost of purchase including the tax percentage
The total cost of purchase = $ 43.49 + $ 2.39195
= $ 45.88195
≈ $ 45.88
Hence , the total cost of Jack's purchase is $ 45.88

Answers
Answer:
A) 3
Step-by-step explanation:
The notation f(x)=[x] represents the greatest integer function, with the integer being less than or equal to x.
Since we have to find the nearest integer smaller than the given number, we can say that greatest integer function always rounds down its input to the nearest integer.
We have to find the value of [3.6]. So we have to round down 3.6 to its nearest integer, which will be 3.
Therefore, the option A gives the correct answer.
Answer: Hello mate!
the function f(x) = [x] is equal to the closest smaller or equal integer to the number x.
for example:
[1] = 1
[1.3] = 1
[1.9998] = 1
then, the closest smaller or equal integer to the number 3.6 is the number 3.
this means that f(3.6) = [3.6] = 3, then the right option is the first one.

Explanation:
____________________________________________________
[AC] / [DF] = 12 cm / 9 cm ;
[BC] / [EF] = x / 15 cm ;
12 / 9 = x / 15 ; Solve for "x" ; {Note: "x" is the length of BC (in cm) ;
Simplify the " (12/9) " ;
→ " 12 / 9 = (12 ÷ 3) / (9 ÷ 3) " ;
= 4 / 3 ;
And rewrite:
→ 4 / 3 = x / 15 ; Solve for "x" ;
_____________________________________________________
Note: Cross-multiply:
Given: "(a/b)" = (c/d)" ; { b[tex] \neq [/tex]0 ; d[tex] \neq [/tex]0 } ;
" a*d = b*c " .
_____________________________________________________
As such:
→ 3x = 15 * 4 ;
→ 3x = 60 ;
Divide EACH SIDE of the equation by "3" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
__________________________________________________
→ 3x / 3 = 60 / 3 ;
→ x = 20 .
____________________________________________________
Answer: The length of BC is: " 20 cm " .
