The scale factor of the blueprint of a wall to the actual wall is 0.07. The area of the actual wall is 36ft² what is the area of the wall on the blueprint?
A) 0.01764ft²
B) 0.07ft²
C) 0.1764ft²
D) 0.252ft²
Answer:
The area of the wall on the blueprint is 0.1764 ft²
Step-by-step explanation:
The scale is the relationship that exists between the magnitudes of a drawing and the actual dimensions.
The scale factor is the ratio of the dimensions in two similar figures. The term "similar figures" refers to figures that have the same shape but different sizes.
The ratio between areas is equal to the squared scale factor. This is, the scale factor for areas is the squared scale factor,
To solve scale problems in this case, then the following proportion must be proposed:
[tex]\frac{representation area}{actual area} =scale factor^{2}[/tex]
Being:
representation area=?actual area=36 ft²scale factor=0.07Replacing:
[tex]\frac{representation area}{36 ft^{2} } =0.07^{2}[/tex]
Solving:
representation area= 0.07²*36 ft²
representation area=0.1764 ft²
The area of the wall on the blueprint is 0.1764 ft²
A jacket usually sells for $57.00. If the jacket is 40% off, and sales tax is 5%, what is the total price of the jacket, including tax?
Answer: $35.91
Step-by-step explanation:
Since the jacket is 40% off, we multiply the original price by 60% to get the price remaining. ($57 x 0.6 = $34.20)
Then, we multiply the new price by 105% (includes the 5% sales tax) to get the total price. ($34.20 x 1.05 = $35.91)

What is -5 1/3 + 2 2/3
Answer:
-2[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Answer:
-8/3 or -2 2/3
Step-by-step explanation:
-5 1/3 + 2 2/3 can be made into the improper fractions -16/3 + 8/3 if you multiply the whole number and the denominator together then add the numerator, so now you do the math:
-16 + 8 = -8
3 stays as the denominator leaving you with -8/3, or -2 2/3

Finding the Square Root of a Perfect Square
Which statements about square roots are true? Check all that apply.
The square root of a positive number cannot be negative.
All positive numbers have two square roots.
0 18 = 9 because 9(2) = 18.
49 = 7 because 7(7) = 49.
25 = 5 because 52= 25.
Answer:
Step-by-step explanation:
The square root of a positive number cannot be negative. False. There are two square roots, one positive and one negative.
All positive numbers have two square roots. True. See above.
0 18 = 9 because 9(2) = 18. Unable to answer; "0 81" is invalid. Note that
√81 = ±9
49 = 7 because 7(7) = 49. Invalid statement. 49 never equals 7. Perhaps you meant √49 = ±7
25 = 5 because 52= 25. Invalid statement. Perhaps you meant √25 = ±5.
Please, before you do any more square root problems, learn how to type the " √ " symbol or equivalent, such as "sqrt( "

How are human activities affecting global warming?
Answer:
Human activities such as driving cars, and working at factories contribute to global warming significantly because burning fossil fuels in cars releases carbon dioxide, which is the largest source of greenhouse gas emissions in the U.S. and as these gases build up, they trap heat in the atmosphere, causing climate change.

3 × (6 × 7 – 2.5 × 4)
Answer: 96
Multiply
3×6×7=126
2.5×4=10
(3)(-10)
Subtract
126-30=96
Answer:
96.
Step-by-step explanation:
Using order of operations:- we deal with the parentheses first:
3 * (6 * 7 - 2.5 * 4) Multiplying before the subtract in the parentheses:
= 3 * (42 - 10) Now do the subtraction in the parentheses:
= 3 * 32
= 96.

△GHI ≅ △KLM what is the m∠KLM
Answer:
64°
Step-by-step explanation:
Both triangles represent a right angle by the small box in the angle.
Right angles = 90°
Since the triangles are congruent, then they would have the same measurements in their angles an sides. All triangles also have a sum of 180°. So, we can just subtract (26 + 90) from 180 to get the third angle.
180 - (26 + 90)
180 - 116
64
So, the m∠KLM is 64°.
What is the solution to the system of equations?
Answer:
(3,2)
Step-by-step explanation:
Here's your given:
y = 4x - 10
y = 2
Because they both equal y, that means they equal each other:
2 = 4x - 10
Add 10 on both sides:
12 = 4x
Then, divide 4 on both sides:
3 = x
This represents the x coordinate.
Normally you would put this value into one of the equations to figure out y, but they already gave us that in the beginning:
y = 2
This represents the y coordinate.
Put the two values together to get: (3,2)

Step-by-step explanation:
(w+1)(w+1)
-------------
w+1
Cancel like terms
w+1 w≠-1
Answer:
w+1
Step-by-step explanation:
when you have a fraction that is composed of multiplied factors you can cancel out the numerator and denominator if they are equal to simplify it. in this cause (w+1) is seen on the top and bottom meaning you can cancel one of them out from the top by cancelling the one on the bottom out.

A used car dealer prices her cars so that she makes a minimum profit of 15% on each car sold. If she acquired a car for $4,500, which inequality can be used to determine the acceptable selling prices, p, of that car? 1.15 p less-than-or-equal-to 4,500 1.15 p greater-than-or-equal-to 4,500 p less-than-or-equal-to 1.15 (4,500) p greater-than-or-equal-to 1.15 (4,500)
Answer:
[tex]p\geq 1.15(4,500)[/tex]
Step-by-step explanation:
If she makes a minimum profit, we need to use the symbol [tex]\geq[/tex], which indicates minimum quality.
Let's call [tex]p[/tex] profit, so the inequality which represent this problem would be
[tex]p\geq 1.15(4,500)[/tex]
The price of the car is multiplied by 1.15, because she must add her profit comission which is 0.15 or 15%.
Therefore, the right answer is the last choice.

You pick a card at random. Without putting the first card back, you pick a second card at random.
What is the probability of picking a 3 and then picking a 3?
Simplify your answer and write it as a fraction or whole number.
Answer:
You have three card : 3, 4, 5 and 6.
You first pick one card randomly, the probability of picking a 3 is:
P = 1/4
You then pick a second card without putting the first card back, the probability of picking a 3 is:
P = 1/3
=> The probability of picking a 3 and then picking a 3:
P = (1/4) x (1/3) = 1/12

[tex]x + 50.75\geq \frac{387}{4} \\\\x\geq \frac{387}{4} -50.75\\subtract \\x\geq \frac{387}{4} - \frac{203}{4} \\solution:\\x\geq 46\\\\\\[/tex]
The answer is: C
Answer:
Yes your answer is c
Step-by-step explanation:
First convert to mixed fraction.
X + 50.75 > 387 / 4
Then subtract 50.75 from both sides
X + 50.75 - 50.75 > 387 / 4 - 50.75
Finally simplify,
X > 46
