Mrs. Jones bought 250 apples for $22 500. She sold 50 for $120 each, and the remain she sold 5 for $1 000 a parcel. (a) State whether she made a profit or loss. (b) Calculate her percentage profit or percentage loss.
Answer:
(a) yes
(b) 104% profit
Step-by-step explanation:
250 apples for $22,500 (were they gold?)
Part 1:
50x$120=$6000
Part 2:
200 sold at $1000 per 5 apples=200/5x1000=$40,000
$40,000+$6000=$46,000
A profit of $23,500
23500/22500=1.044 or 104% profit

A chemical company makes two brands of antifreeze. The first brand is 20% pure antifreeze, and the second brand is 45% pure antifreeze. In order to obtain 30 gallons of a mixture that contains 30% pure antifreeze, how many gallons of each brand of antifreeze must be used?
Answer:
First brand = 18 gallons
Second brand = 12 gallons
Step-by-step explanation:
Let the first brand brand be A and the second brand be B.
Thus, since he wants to obtain 30 gallons of a mixture that contains 30% pure antifreeze, then we have;
A + B = 30 - - - (eq 1)
Also; The first brand is 20% pure antifreeze, and the second brand is 45% pure antifreeze. Thus;
0.2A + 0.45B = (0.3 × 30)
0.2A + 0.45B = 9 - - - (eq 2)
From eq 1, we have; A = 30 - B
Put 30 - B for A in eq 2;
0.2(30 - B) + 0.45B = 9
6 - 0.2B + 0.45B = 9
0.25B = 9 - 6
0.25B = 3
B = 3/0.25
B = 12
Thus, A = 30 - 12 = 18 gallons

for what value of the variable the value of the expression 4(5x-8) is 4 more than the value of the expression 2(4-x)
Answer:
For x=2, the expression 4(5x-8) will be 4 more than the expression 2(4-x)
Step-by-step explanation:
Given expressions are;
4(5x-8) and 2(4-x)
For 4 more than the second expression, we will add 4 with second expression.
4(5x-8) = 2(4-x) + 4
20x - 32 = 8 -2x +4
20x + 2x = 12 + 32
22x = 44
Dividing both sides by 22
[tex]\frac{22x}{22}=\frac{44}{22}\\x=2[/tex]
Hence,
For x=2, the expression 4(5x-8) will be 4 more than the expression 2(4-x)

Gasoline price changed from $3.25/gallon to $1.30/gallon in one week. What is the percent of change? PLZ I need it fast!! I will give 10 points
Answer:
The percent of change is -60%.
Step-by-step explanation:
To find the percentage of change, we find the percentage of the final value, considering the initial valuie is 100%, and then we subtract 100% by the percengate found.
In this question:
Initial price of $3.25 per gallon, which is 100% = 1.
Final value of $1.30, which is x. So
$3.25 - 1
$1.30 - x
[tex]3.25x = 1.30[/tex]
[tex]x = \frac{1.30}{3.25}[/tex]
[tex]x = 0.4[/tex]
The initial value of 0.4 = 40% of the initial value.
So the percent of change is a decrease of 100% - 40% = 60%, that is, -60%.

TA
Answer:
[tex]\frac{5}{6}[/tex]
Step-by-step explanation:
Fraction Models
Given a number N, to model the process of sharing N into M equal parts we use the division N/M or the fraction
[tex]\frac{N}{M}[/tex]
There are N=5 cakes to be shared between M=6 people, thus the fraction that represents or models the situation is
[tex]\mathbf{\frac{5}{6}}[/tex]

Chuck and holly are saving money to buy a car. Chuck has $500.00 already and is going to save $100.00 a month. Holly has $1000.00 and plans on saving 50 a month and it takes 10 months for their savings to equal. Write anequation
Answer:
500 + 100m = 1000 + 50m
Step-by-step explanation:
In order to form an equation we need atleast on variable which in this scenario would be the number of months (m). We can say that we know that sooner or later their savings will equal. Therefore, we can create the following equations for each of their savings progress which are equal to one another...
500 + 100m = 1000 + 50m
This equation if solved would give us the value of 10 for the variable m, meaning that their savings will equal in 10 months. To find out how much each will have in 10 months we can simply grab one half of the equation and substitute 10 for m
500 + 100(10) = x
500 + 1000 = x
1500 = x
Finally, we can see that after 10 months they would both have $1500 saved up.

Answer:
a = 66⁰
b = 33⁰
Step-by-step explanation:
Given;
∠ABC = 114⁰
To calculate a⁰;
a + 114 = 180⁰ (opposite angles of a quadrilateral are supplementary)
a = 180 - 114
a = 66⁰
To calculate b⁰;
Line AB = Line BC, thus, ∠BAC = ∠BCA
∠BAC = b, then ∠BCA = b
b + b + 114 = 180 (sum of angles in a triangle)
2b = 180 - 114
2b = 66
b = 66/2
b = 33⁰
Determine the 25th term in the sequence defined by a= 8 + 2(n - 1)
Answer:
The 25 th term in the sequence
a₂₅ = 56
Step-by-step explanation:
Explanation
Given that the [tex]n^{th}[/tex] term of sequence
aₙ = 8 + 2 ( n-1)
put n =1
a₁ = 8 + 2( 1-1) = 8+0 =8
first term a₁ = 8
put n=2
a₂ = 8 + 2( 2-1) = 8+2 =10
Second term
a₂ = 10
and so on
put n =25
a₂₅ = 8 + 2( 25-1) = 8+2(24) = 8 + 48 = 56
Given sequence
8 , 10 ,.......56,....

2.5m + 10 = 1.6m - 6
Answer:
m = 17.78.
Step-by-step explanation:
Given the algebraic expression;
2.5m + 10 = 1.6m - 6
To find the value of m;
First of all, we would collect like terms.
2.5m - 1.6m = -6 - 10
0.9m = -16
m = -16/0.9
m = 17.78

Answer:
Hope it works for U
Step-by-step explanation:
As given to convert first 2 days in to months
we know that,
1 day=0.0329 months
2day= 2*0.0329 months
2 day= 0.0657 months
now convert to nearest hundred
Rounded to the nearest 0.01 or
the Hundredths Place, we get
2 day = 0.06 months Ans.....The side lengths are 9,12,18. is this a right triangle?
