If each 4 in. on the scale drawing below equals 8 feet, what is the actual area of the shape in square units?
Answers
Answer:
the answer is 40 I donk know y
Answer: 384 ft. squared
Step-by-step explanation:
Hey!
So for this problem we first need to convert our scale lengths to feet. Since 4 in. equals 8 ft. that would make the 12 in side 24 ft. long because 12 divided by 4 is 3 and 3 time 8 is 24. We do this because we need to figure out how many times 4 inches are in each length because that how many time the 8ft is in the real length.
Next, we would do the same for the next side and divide 8 by 4 which is 2 and then we multiple 8ft by 2. We then get 16 ft which is our other side length.
After that, we just do our area formula which is length x width or in this case 16 x 24. This gets us 384 and then we add our unit and squared at the end and have our answer.
Hope this helped! :D

James needs to choose a cell phone plan. Sprint costs $40 per month and $0.12 per text message. Verizon is only $25 per month, but each text message costs $0.15. Write an equation that could be used to solve for how many texts he would have to send for the Sprint plan to be the same as Verizon.
Answers
Answer:
y = 40 + 0.12x
y = 25 + 0.15x
Step-by-step explanation:
Hey Dylan! We're gonna use variable x to represent number of messages sent.
The $40 & $25 dollar payments won't be changed, so they can't have a variable applied to them.
Since it's 12 or 15 cents per text, that's where we wanna put the x.
Since both equations are equal to y, we can set them equal to each other.
40 + 0.12x = 25 + 0.15x
15 = 0.03x
x = 500 messages
Hope this helps! :)

Step-by-step explanation:
I used the elimination method to solve this. so we can see that there is 100 boxes and we need to 75 to be shaded. only C and D have 75 squares shaded so we can eliminate A and B. now we have to divide by 5. Square C is divided 3 times while square D is divided 5 times, so square D is correct.

what price did he purchese each sari if his profit is Rs. 42000 ?
please answer with explanation
if u ans with no explanation i will report your answer
Answers
Answer:
Rs. 1315
Step-by-step explanation:
He bought 300 saris
0.7(300) were sold at 1500 / piece
0.3(300) were sold at 1350/ piece
210 were sold at 1500/ piece = 315000
90 were sold at 1350/piece = 121500
Total amount = 315000+121500 = 436500
Profit = 42000
Subtract:
436500 - 42000 = 394500
394500 is the price for 300 saris
Divide by 300
394500 / 300 = 1315
He purchased one sari at 1315

A) [tex]x = y^{2}[/tex]

An equation is a function of [tex]x[/tex] when [tex]x[/tex] is the independent variable, that is:
[tex]y = f(x)[/tex] (1)
Where [tex]y[/tex] is the dependent variable.
According to this, [tex]x = y^{2}[/tex] does not represent a function of [tex]x[/tex], since the independent variable is a function of [tex]y[/tex], that is, [tex]x = f(y)[/tex]. Therefore, the correct answer is A.

C (w2 - 6)(w2 – 6)
D (w2 + 6)(w2 – 6)

The equivalent expression of [tex]w^{4} -36[/tex] is [tex](w^{2} -6)(w^{2} +6)[/tex].
What is equivalent expression?Equivalent expressions are expressions that work the same even though they look different.
According to the given question.
we have an expression [tex]w^{4} -36[/tex]
The equivalent expression of the above expression can be given by
[tex]w^{4} -36[/tex]
⇒ [tex](w^{2}) ^{2} -(6)^{2}[/tex]
⇒[tex](w^{2}-6)(w^{2} +6)[/tex] (by using the property [tex]a^{2} -b^{2} = (a-b)(a+b)[/tex] )
Hence, the equivalent expression of [tex]w^{4} -36[/tex] is [tex](w^{2} -6)(w^{2} +6)[/tex].
Thus, option D is correct.
