The correct option is A. 0.156. The number (1.092×10¹) is 156 times larger than number (7×10⁻¹).
What is defined as the scientific notations?Scientific notation is a method of writing extremely large or extremely small numbers. Whenever a number among 1 and 10 is multiplied by a power of 10, it is written in scientific notation. 650,000,000, for example, can be composed in scientific notation as 6.5× 10⁸.Scientific notation is a method of writing extremely large or extremely small numbers in a way that makes them easier to read as well as work with. A number is expressed as the product of an amount that is equal to one but less than ten and an integral power of ten.For the given number;
The number 1.092×10¹ can be written as; 10.92 after multiplication with 10.
Similarly, the number 7×10⁻¹ can be written as 0.7 after diving with 10.
Now, divide larger number by 0.7
= 10.92/0.7
= 156
Thus, the number 1.092×10¹ is almost 156 time greater than (7×10⁻¹).

Given (x,7) and (−1,y) find x and y such that the midpoint between these two points is (3,5)
The solution to the system of linear equations is (x, y) = (7, 3).
How to find the missing coordinates of the two ends of a line segmentHerein we find that the coordinates of the midpoint and part of the coordinates of the ends of the line segment are known. We must determine the values of the missing coordinates by the midpoint formula:
0.5 · (x, 7) + 0.5 · (-1, y) = (3, 5)
Which is equivalent to the system of linear equations:
0.5 · x - 0.5 = 3 (1)
3.5 + 0.5 · y = 5 (2)

4.338 × 101 mg
4.3 × 101 mg
4 × 101 mg
3.62 × 100 mg
Taking into account the definition of Scientific notation, the correct answer is the first option: the total mass of the paperclips in the box is 4.338×10¹ mg.
Scientific notationScientific notation is a quick way to represent a number using powers of base 10.
The numbers are written as a product:
a×10ⁿ
where:
a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.n is a whole number, which is called an exponent or an order of magnitude. Represents the number of times the point decimal is shifted. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.Total mass of the paperclips
In this case, you know that:
The mass of a paperclip is 6.0×10⁻⁴ mg. A box of paperclips has 7.23×10⁴ paperclips.To know the total mass of the paperclips in the box, you must multiply the number of paperclips in the box by the mass of each paperclip:
7.23×10⁴×6.0×10⁻⁴
To multiply numbers in scientific notation, you multiply the numbers that are not powers of 10 (the numbers previously called "a") and add the exponents of 10.
(7.23×6.0)×10⁴⁻⁴= 43.38×10⁰= 4.338×10¹ mg

Given the lease terms below from a local car dealership, what is the total cash due at
signing if the dealership requires down payment, security deposit, first month's
payment and the acquisition fee at signing?
Length of lease = 24 months
MSRP of the car = $22, 750
Purchase value of the car after lease = $16, 900
Down payment = $1,800
Monthly payment = $425
Security deposit = $375
Acquisition fee = $300
The total cash due at signing if the dealership requires down payment, security deposit, first month's payment and the acquisition fee at signing is 2400 + 375 + 500 = 3275
When you buy a car, you don't make monthly payments at the beginning. Plus, you don't care how much the buyout costs when you close the lease, that's after you've had it for two years.
You must take care of the deposit, this is your good faith commitment to the rental car. In addition, you may have to pay a deposit based on your credit, and the acquisition fee is what you would pay a broker or dealer to get the car to you if you wanted it from somewhere else.

To manufacture an automobile requires painting, drying, and polishing. Epsilon Motor Company produces three types of cars, the Delta, the Beta, and the Sigma. Each Delta requires 11 hours for painting, 5 hours for drying, and 3 hours for polishing. A Beta requires 17 hours for painting, 8 hours for drying, and 4 hours for polishing, and a Sigma requires 4 hours for painting, 5 hours for drying, and 1 hour for polishing. If the company has 253 hours for painting, 149 hours for drying, and 63 hours for polishing per month, how many of each type of car are produced?
Step-by-step explanation:
d = number of Delta cars
b = number of Beta cars
s = number of Sigma cars
253 = 11d + 17b + 4s
149 = 5d + 8b + 5s
63 = 3d + 4b + 1s
s = 63 - 3d - 4b
149 = 5d + 8b + 5(63 - 3d - 4b) =
= 5d + 8b + 315 - 15d - 20b = -10d - 12b + 315
-166 = -10d - 12b
-83 = -5d - 6b
83 = 5d + 6b
5d = 83 - 6b
d = (83 - 6b)/5
with these 2 "identities" we are going into the 3rd equation and solve for the third variable (b), followed by solving the first 2 identities :
253 = 11((83 - 6b)/5) + 17b + 4(63 - 3((83 - 6b)/5) - 4b)
1265 = 11(83 - 6b) + 85b + 20×63 - 12(83 - 6b) - 80b
1265 = -(83 - 6b) + 5b + 1260
5 = -83 + 6b + 5b
88 = 11b
b = 8
d = (83 - 6b)/5 = (83 - 48)/5 = 35/5 = 7
s = 63 - 3d - 4b = 63 - 3×7 - 4×8 = 63 - 21 - 32 = 10

*
Answer: m∠B=53°
Step-by-step explanation:
A property that is inherent in a trapezoid of any kind: the sum of the angles adjoining a side is equal to 180°
Hence,
(32x-1)+(14x-3)=180
32x-1+14x-3=180
46x-4=180
46x-4+4=180+4
46x=184
Divide both parts of the equation by 46:
x=4
m∠B=14x-3
m∠B=14(4)-3
m∠B=56-3
m∠B=53°

What is the conjugate?
a √a-1
Step-by-step explanation:
In maths, Conjugates are defined as a pair of binomials with identical terms but parting opposite arithmetic operators in the middle of these similar terms. For example, p – q is the conjugate of p + q.
complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but opposite in sign. That is, the complex conjugate of {\displaystyle a+bi} is equal to {\displaystyle a-bi.}
The math conjugate of a number is a number that when multiplied or added to the given number results in a rational number. For example,
The conjugate of a surd 6 + √2 is 6 - √2.
The conjugate of a complex number 5 - 3i is 5 + 3i.
You are the owner of four Taco Bell restaurant locations. You have a business loan with Citizens Bank taken out 60 days ago that is due in 90 days. The amount of the loan is $50,000, and the rate is 9.5% using ordinary interest.
You currently have some excess cash: $35,000. Due to situations beyond your control, you, as the owner, must make an immediate business decision now to pursue only one of these two choices:
1) sending all of the $35,000 to Citizens Bank as a partial payment on your loan, or
2) using the $35,000 to purchase serving supplies such as food containers, cups, and plastic dinnerware for your inventory. This is the last day to take advantage of the opportunity to save some money due to a special discount price that is "10% off" the normal cost of $35,000 for these items.
Consider these calculations:
(a)
How much interest (in $) will you save on this loan if you make the partial payment and don't purchase the additional serving supplies? (Round your answer to two decimal places.)
$
(b)
How much money (in $) will you save if you purchase the serving supplies with the discount and don't make a partial payment on the loan? (Round your answer to two decimal places.)
$
(c)
How much (in $) will you save by purchasing the discounted serving supplies rather than making the partial payment? (Hint: Find the difference between the savings on the supplies found in part (b) and the savings on the loan interest found in part (a). Round your answer to two decimal places.)
$
(d)
What other factors should you consider before making this decision?
The amount saved by repaying the loan early is $831.25
The amount of discount received by purchasing supplies is $3,500
The net amount saved by purchasing supplies rather than repaying loan is $2,668.75
What is ordinary interest?
Ordinary interest is the interest computation that is based on 360-day a year count rather than 365-day year count, hence, in determining the amount saved by paying $35,000 out of the amount due to Citizens Bank, we time-apportion the interest for 90 days with respect to 360 days not 365 days.
Amount saved in interest=$35,000*9.5%*90/360
Amount saved in interest=$831.25
Using the $35,000 to purchase serving supplies, 10% discount is given off the normal cost of $35,000
Amount saved with discount=10%*$35,000
Amount saved with discount=$3,500
The difference between discount on supplies and interest saved=$3,500-$831.25
The difference between discount on supplies and interest saved=$2,668.75
The other factors to consider before making the final decisions include, the fact the loan is more important than the supplies because the loan relates to the firm's financing rather than operational needs of supplies
Secondly, the amount saved in interest may be more if another loan of $35,000 can be borrowed elsewhere with significant lower interest rates
