Answer:
D) 31
Step-by-step explanation:
2x-7+2x+63=180

4x=180-56
4x=124
x=124/4
x=31
Answer:
(d) x = 31
Step-by-step explanation:
(2x)° + (2x - 7)° + 63° = 180°
4x - 7 + 63 = 180
4x = 180 - 56
4x = 124

The cost of a hamburger is $1.15 more than an order of large fries. Bill bought two hamburgers and an order of fries for a total of $8.60. What is the price of each item? Give your answer in full sentences.
Answer:
The order of large fries costs $ 2.10, while each hamburger costs $ 3.25.
Step-by-step explanation:
Given that the cost of a hamburger is $ 1.15 more than an order of large fries, and Bill bought two hamburgers and an order of fries for a total of $ 8.60, to determine what is the price of each item, the following calculation must be performed:
X + X + 1.15 + X + 1.15 = 8.60
3X + 2.30 = 8.60
3X = 8.60 - 2.30
X = 6.30 / 3
X = 2.10
Thus, each order of large fries costs $ 2.10, while each hamburger costs $ 3.25.

A survey was conducted to find the frequency with which people go to the movies. A group of 120 people in a mall were asked about how often they go out for a movie and It was found that 36 people go to movies at least once in a month. Which of these is an example of descriptive statistics
Answer:
30% of the people surveyed in the mall go to movies at least once in a month
Step-by-step explanation:
A descriptive statistic would refer to a summary where it explain in quantitative way from the information collected also it it is used to analyze it. The parameter and descriptive statistics would be the percentage for the surveyed people that goes to the mall for watching out the movies at least for one time in a month
Here 30% come from
= 36 ÷ 120
= 30%

A rectangular piece of tin has an area of 1056 square inches. A square of 3 inches is cut from each corner, and an open box is made by turning up the ends and sides. If the volume of the box is 2052 cubic inches, what were the original dimensions of the piece of tin. PLEASE SHOW WORK
Answer:
44 inches and 24 inches
Step-by-step explanation:
Let [tex]l,b[/tex] denotes length and breadth of a rectangle.
[tex]lb=1056[/tex]
A square of 3 inches is cut from each corner, and an open box is made by turning up the ends and sides.
New length [tex]=l-6[/tex] inches
New breadth [tex]=b-6[/tex] inches
Height of box [tex]=3[/tex] inches
Volume of box = length × breadth × height
[tex](l-6)(b-6)3=2052[/tex]
[tex]lb-6l-6b+36=684\\6(l+b)=408\\l+b=68\\b=68-l[/tex]
Put [tex]b=68-l[/tex] in [tex]lb=1056[/tex]
[tex]l(68-l)=1056\\l^2-68l+1056=0\\l^2-44l-24l+1056=0\\l(l-44)-24(l-44)=0\\(l-24)(l-44)=0\\l=24,44[/tex]
At [tex]l=24,b=\frac{1056}{24}=44[/tex] inches
At [tex]l=44,b=\frac{1056}{44}=24[/tex] inches
7 more than a number ?
A)n+7
B)7+n
C)7-n
Answer:
B)7+n
Step-by-step explanation:
Answer:
A but see below.
Step-by-step explanation:
A is likely the best answer, although B is also correct. However you should write things in the other they are given.
n + 7 is the very best way to answer.
7 + n is not wrong but maybe not wanted.
from the top of a tower 80m high, 2 boats are
seen in a direction due south. The angles of
depression of the boats from the top of the tower
are 30°and 45°respectively, find the distance
between the boat
Step-by-step explanation:
Height of tower - 80m
Distance between foot of tower and boat 1 = x
Distance between boat 1 and boat 2 =y
Tan 45 = 1 = 80/x
x = 80
Tan 30 = 1 / root 3 = 80 / 80 + y
y = 80 root 3 + 80

To solve this you would do 1350/2700 which is 50%
Two chemical plants, one at Macon and one at Jonestown, produce two types of fertilizer, low phosphorus (LP) and high phosphorus (HP). At each plant, the fertilizer is produced in a single production run, so the two types are produced in fixed proportions. The Macon plant produces 1 ton of LP and 3 tons of HP in a single operation, and it charges $600 for what is produced in one operation, whereas one operation of the Jonestown plant produces 1 ton of LP and 1 ton of HP, and it charges $1,000 for what it produces in one operation. If a customer needs at least 100 tons of LP and 180 tons of HP, how many production runs from each plant should be ordered to minimize the cost.
Answer:500
Step-by-step explanation:
There are 100 production runs from each plant should be ordered to minimize the cost.
What is Production?
The process of making or manufacturing goods and products from raw materials or components is called Production.
The Macon plant produce 1 ton of LP and 3 tons of HP in single operation, and it charge $600 for what is produced in one operation.
And, One operation of Jonestown plant produce 1 ton of LP and 1 ton of HP, and it charges $1,000 for what it produces in one operation.
And, A customer needs at least 100 tons of LP and 180 tons of HP,
Now, A graph of the requirements shows the feasible region is bounded by a polygon with vertices (Macon and Jonestown) as,
= (0, 180), (40, 60), (100, 0).
Hence, By checking costs of these solutions, we find the lowest cost to be obtained when 100 production runs should be ordered from Macon.
So, There are 100 production runs from each plant should be ordered to minimize the cost.

Solving linear equations
Answer:
1. P = [tex]\frac{I}{rt}[/tex]
2. y = [tex]\frac{6 - 3x}{11}[/tex] or [tex]\frac{-3x +6}{11}[/tex] (depending on how you want the equation arranged)
3. c = [tex]\frac{a-bd}{b}[/tex]
4 t = [tex]\frac{A - p }{pr}[/tex]
Step-by-step explanation:
1. I =Prt for P:
I = Prt divide both sides by rt to isolate P
P = [tex]\frac{I}{rt}[/tex]
2. 3x + 11y = 6 for y
3x + 11y = 6 subtract 3x from both sides
11y = 6 - 3x divide both sides by 11
y = [tex]\frac{6 - 3x}{11}[/tex] or [tex]\frac{-3x +6}{11}[/tex] depending on how you want the equation arranged
3. a = b(c + d) for c
a = b(c + d) distribute b to (c+d)
a = bc + bd subtract bd from both sides
a - bd = bc divide both sides by b
c = [tex]\frac{a-bd}{b}[/tex]
4. A = p + prt for t
A = p + prt subtract p from both sides
A - p = prt divide both sides by pr
t = [tex]\frac{A - p }{pr}[/tex]
