Answer:
Step-by-step explanation:
You can't do this without some conversion of units. You can do it with just the definition of a Liter
1 Liter has 1000 mL
1000mL > 800 mL
5 Liters requires a conversion
5 Liters = 5 * 1000 = 5000 mL
Difference = Sara - Teresa use to determine how much more Sara has
Difference = 5000 - 800
Difference = 4200
Sara has 4200 more mL than Teresa

Set the function = 0, factor, and use the zero product property to find the zeros of the function.
f(x) = x2 + 7x - 60
Answer:
-12; 5
Step-by-step explanation:
x^2 + 7x - 60 = 0
D = b^2 - 4ac
D = 7 * 7 + 60 * 4 * 1 = 289
sqrt(D) = sqrt(289) = 17
x₁ = (-b - √D) / 2a = (-7 - 17) / 2 = -24 / 2 = -12
x₂ = (-b + √D) / 2a = (-7 + 17) / 2 = 10 / 2 = 5

If 2/3x - 1=4, then x =?
express x^2-8x+5 in the form (x-a)^2-b where a and b are intergers
Answer:
(x - 4)^2 - 11
Step-by-step explanation:
Here, the question asks you to complete the square. The steps to do so are the following:
ax^2 + bx + c = a(x - b/2 x)^2 -(b/2)^2 + c
1. halve the x coefficient and put it with x as a binomial squared
2. minus the new coefficient squared
3. collect like terms
so let's do it for this question:
x^2 - 8x + 5
step 1:
half of -8, is -4, so we'll get:
= (x - 4)^2 + 5
However this isn't equal to x^2 - 8x + 5, but to x^2 - 8x + 16 + 5. Therefore we must get rid of 16 (step 2). You will notice 16 = (-4)^2 (from the first formula I gave.)
= (x - 4)^2 - 16 + 5
step 3:
= (x - 4)^2 - 11
Answer:
(x - 4)² - 11
Step-by-step explanation:
x² - 8x + 5
using the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² - 8x
x² + 2(- 4)x + 16 - 16 + 5
= (x - 4)² - 11
a manufacturer sells an article to a wholeseller at a profit of 18%,the wholesaler sells it to a retailer at a profit of 20%.the retailer sells it to a customer at a profit of 25%.if the customer pays ₹30.09 for it,find the cost of the manufacturer
Answer:
the cost price of manufacturer = RS. 14.80
Step-by-step explanation:
the retailers profit = profit percent of sold amount
= 25% of 30.09
= 25/100 × 30.09
= 7.5225
here, the cost price of retailer =
sold amount- profit amount
or, CP = 30.09 - 7.5225
= 22.5675
now, profit of whole seller =
profit% of sold amount
or, 20% of SP
20/100 × 22.5675
= 4.5135
CP = SP - Profit
or, CP = 22.5675- 4.5135
CP = 18.054
now, profit of manufacturer = profit℅ of SP
= 18% of 18.054
= 18/100 × 18.054
= 3.24972
or, CP of manufacturer = SP - profit amount
= 18.054 - 3.24974
= 14.80428
Therefore, cost price of manufacturer = 14.80

The area of a rectangle is 32 inches squared. If the length is 8 inches, what is the *perimeter* of the rectangle?
Answer:
Step-by-step explanation:
w (width) = 32/8
w = 4
p (perimeter) = 2w + 2l
p = (2 x 4) + (2 x 8)
p = 8 + 16
p = 24

Hey there!
2/3x + 5 = 1
SUBTRACT 5 to BOTH SIDES
2/3x + 5 - 5 = 1 - 5
SIMPLIFY IT!
2/3x = 1 - 5
2/3x = -4
MULTIPLY 3/2 to BOTH SIDES
2/3x * 3/2 = -4 * 3/2
SIMPLIFY IT!
x = -4 * 3/2
x = -6
Therefore, your answer is: x = -6
Good luck on your assignment & enjoy your day!
~Amphitrite1040:)
Answer:
2/3x + 5=1
To solve for x, we must isolate it by administering inverse operations.
In this equation, we can see 2/3x is being added to 5.
We should discard the constants first.
The inverse operation of addition, is subtraction.
So we subtract 5 from both sides;
-5 -5
2/3x = -4
Now, we are left with a coefficient, so to get rid of the coefficient we utilize the inverse operation of multiplication, which is division.
Dividing by 2/3 is the same as multiplying by 3/2.
So multiply both sides by 3/2;
*3/2 *3/2
x = -4(3)/2
x = -12/2
x = -6

A group of 125 teenagers were asked which of the following activities they would most likely choose to spend their free time doing: reading a book, watching television, playing video games, or listening to music. The results are displayed in the circle graph below.
What is the difference in percent between those who chose reading a book and those who chose to listen to music?
a. 16%
b. 8%
c. 12%
d. 4%
Answer:
12%
Step-by-step explanation:
Read a book = 16%
Listen to music = 28%
We can read the question in different ways:
1. The simple difference between the two is 12%
2. Out of the sample, the two groups include:
15 chose books
35 chose music
Within this sample of 50 teenagers,
(15/50) or 30% chose books, and
(35/50) or 70% chose music
That makes a difference of 40%
I would chose the first interpretation, 12% [Especially since 40% is not an option.]
