George is comparing two different phones. The screen of phone A has a width of 5.3 cm. The width of the screen on phone B is 5 and one-third cm. Which statement explains which phone has the wider screen? The screens have the same width. Screen A is wider, because 5.3 is greater than 5 and one-third.. Screen B is wider, because 5.3 is greater than 5 and one-third.. Screen B is wider, because 5 and one-third is greater than 5.3.
Answer:
The answer is "Screen B is wider , because 5.3 is greater than 5 and one-third".
Step-by-step explanation:
The mobile display unit must be made similar. Phone A uses a decimal device, and telephone B uses a fraction in this case.
It's easier for you to use. Attempt using the decimal. The width of the phone B fraction could then be translated to decimal width. The computing is:
= 5 cm + [tex]\frac{1}{3}[/tex] cm
= 5 cm + 0.333cm
= 5.333 cm
It is evident from here that the wider screen of Phone B is than that of Phone A.
Answer:
They are all the same width

An aircraft factory manufactures airplane engines. The unit cost (the cost in dollars to make each airplane engine) depends on the number of engines made. If engines are made, then the unit cost is given by the function . What is the minimum unit cost?C(x)=x^2-520x+73458
Answer:
Minimum unit cost = 5,858
Step-by-step explanation:
Given the function : C(x)=x^2−520x+73458
To find the minimum unit cost :
Take the derivative of C(x) with respect to x
dC/dx = 2x - 520
Set = 0
2x - 520
2x = 520
x = 260
To minimize unit cost, 260 engines must be produced
Hence, minimum unit cost will be :
C(x)=x^2−520x+73458
Put x = 260
C(260) = 260^2−520(260) + 73458
= 5,858

Step-by-step explanation:
Answer:
Aight mate
Step-by-step explanation:
So every triangles angles will add up to 180 degrees no matter the triangle. Now a circle is 360 and a line is 180. Look at the line that A and C are on this line equals 180. So angle c and d added together make 180 and angles a b and c added together make 180. so if a+b+c = c+d then a+b=c. I hope thaqtmakes sense.

Answer:
3(−x−1)(x−3)
Step-by-step explanation:
the equation y=mx+b is given. solve the equation for b
Answer:
b = y - mx
Step-by-step explanation:
Given
y = mx + b ( isolate b by subtracting mx from both sides )
y - mx = b
Answer:
b=y-mx
Step-by-step explanation:
You need to get b by itself, so you subtract mx.
Suppose you work for a large coffee distributor that has a secret coffee blend it sells to local stores. You
mix the Tanzanian blend with the Queen City blend, but always in the same proportion. Yesterday, you
mixed 40 pounds of the Tanzanian blend with 8 pounds of the Queen City blend. Today, there is 20 pounds
of the Tanzanian coffee left in stock. How many pounds of the Queen City coffee should you mix with it to
get your secret blend?
Quantity of Tanzanian blend used in my secret coffee blend = 40 pounds
Quantity of Queen city blend used in my secret coffee blend = 8 pounds
The ratio of Tanzanian blend to Queen city blend in my coffee blend = 40 : 8
Quantity of Tanzanian blend with me = 20 pounds
Quantity of Queen city bend needed to make my secret coffee blend =
Let the quantity of Queen city blend I will need be x .
[tex] \frac{40}{8} = \frac{20}{x} [/tex]
[tex]8 \times 20 = 40 \times x[/tex]
[tex]160 = 40x[/tex]
[tex]x = \frac{160}{40} [/tex]
[tex]x = 4[/tex]
Therefore , I need to mix 4 pounds of queen city blend with my 20 pounds of Tanzanian blend to get my secret coffee blend .
4 pounds of the Queen City coffee should you mix with it to get your secret blend.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given that,
Yesterday If we mixed 40 pounds of the Tanzanian blend with 8 pounds of the Queen City blend.
In the same proportion, today there is 20 pounds of the Tanzanian coffee left in stock.
We need to calculate how many pounds of the Queen City coffee should you mix with it to get your secret blend.
Let x be the pounds of the Queen City coffee should you mix with it
Let us form a equation
40/8=20/x
Apply cross multiplication
40x=160
Divide both sides by 40
x=4
Hence 4 pounds of the Queen City coffee should you mix with it to
get your secret blend.

Dividing Fractions
The division of two fractions \frac{a}{b} and \frac{c}{d} is written as:
[tex]\displaystyle \frac{\frac{a}{b}}{ \frac{c}{d}}[/tex]
This division is usually easier done by multiplying the numerator by the reciprocal of the denominator:
[tex]\displaystyle \frac{\frac{a}{b}}{ \frac{c}{d}}=\frac{a}{b}\cdot \frac{c}{d}[/tex]
Jessie was dividing these two fractions:
[tex]\displaystyle \frac{\frac{1}{4}\ pounds}{ \frac{1}{8}\ quart}[/tex]
And got the incorrect result
[tex]\displaystyle \frac{1}{32}\ \text{ pound per quart}[/tex]
This mistake was probably the result of multiplying both fractions instead of dividing them.
The correct operation is:
[tex]\displaystyle \frac{\frac{1}{4}}{ \frac{1}{8}}=\frac{1}{4}\cdot \frac{8}{1}=\frac{8}{4}=2[/tex]
The correct result is 2 pounds per quart

Rory is at the local mall and her favorite type of jeggings are on sale. The jeggings are now
priced at $7 per pair, tax free. She has $27 with her, but she needs to have $6 leftover to
spend on a movie theater ticket.
Which inequality represents how many pairs of jeggings Rory can buy, where / represents
the number of jeggings?
Answer:
j ≤ 3
Step-by-step explanation:
Since she has $27 with her and needs a balance if $6, the amount of money she can spend on buying the jeggings will be $27-$6 = $21
This means that she has $21 to spend on buying the jeggins
From the question, one jeggings cost $7, so the maximum number of jeggings she can buy is 21/7 = 3
So the inequality that represents this will be;
j ≤ 3
This is because she can decide to buy less than 3, but never can she buy more than 3 because of her budgetary constraints
A delivery person uses a service elevator to bring boxes of books up to an office. The delivery person weighs 160 lb and each box of books weighs 40 lb. The maximum capacity of the elevator is 790 lb. How many boxes of books can the delivery person bring up at one time?
The delivery person can bring up
nothing boxes of books.
Answer:
15
Step-by-step explanation
So, since the weight of the delivery person is 160 lbs... and the weight limit of the elevator is 790 lbs... Then you could subtract. If you subtract 790 lbs and 160 lbs you get 630 lbs.
So, this means that 630 lbs of boxes can go in the elevator
Since each box weighs 40 lbs, then you could divide the remaining pounds that could go on the elevator and the weight of each box. If you divide 630 lbs and 40 lbs, then you would get 15.75, but you can't carry a 75th of a box. So you in this circumstance, you would round down 15.75 to 15.
In conclusion, that's how I got my answer of 15
