Answers
Question:
The cost of 12 kg sugar is $240 what will be the cost of 3 kg sugar.
Given:
Cost of 12 kg sugar = $240To find?
cost of 3 kg sugarAnswer :
To find cost of 3kg sugar first we have to find cost of 1 kg sugar.
Cost of 1 kg sugar = Cost of total no. of sugar ÷Total sugar Cost of 1 kg sugar = $240/12Cost of 1 kg sugar = $20Now Let's find cost of 3 kg sugar
Cost of 3kg sugar = total no of sugar ×Cost of 1 kg sugar
Cost of 3kg sugar = 3×$20
Cost of 3kg sugar = $60

What is -8(2-3w)-5
Please explain!
Answers
Answer:
24w - 21
Step-by-step explanation:
-8(2 - 3w) - 5
We first expand the -8
-16 + 24w - 5
We then add -16 to -5
-16 + -5
= -21
We get the 24w, put in in the equation and get 24w - 21
Answer:
24w−21
Step-by-step explanation:
Factoring 24w2+10w-21
The first term is, 24w2 its coefficient is 24 .
The middle term is, +10w its coefficient is 10 .
The last term, "the constant", is -21
Step-1 : Multiply the coefficient of the first term by the constant 24 • -21 = -504
Step-2 : Find two factors of -504 whose sum equals the coefficient of the middle term, which is 10 .
-504 + 1 = -503
-252 + 2 = -250
-168 + 3 = -165
-126 + 4 = -122
-84 + 6 = -78
-72 + 7 = -65
-63 + 8 = -55
-56 + 9 = -47
-42 + 12 = -30
-36 + 14 = -22
-28 + 18 = -10
-24 + 21 = -3
-21 + 24 = 3
-18 + 28 = 10 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -18 and 28
24w2 - 18w + 28w - 21
Step-4 : Add up the first 2 terms, pulling out like factors :
6w • (4w-3)
Add up the last 2 terms, pulling out common factors :
7 • (4w-3)
Step-5 : Add up the four terms of step 4 :
(6w+7) • (4w-3)
Which is the desired factorization
3. Let sin 21 = 0.358. What is the value of x for cos x=0.358?
Answers
Answer:
[tex]\cos(69)[/tex]
Step-by-step explanation:
We will use the co-function identity for sine, where:
[tex]\sin(x)=\cos(90-x)[/tex]
Since sin(21)=0.358=cos(x). This means that:
[tex]21=90-x[/tex]
Solve for x. Add x to both sides:
[tex]x+21=90[/tex]
Subtract 21 from both sides:
[tex]x=69\textdegree[/tex]
Hence:
[tex]\sin(21)=\cos(69)\approx0.358[/tex]
An investment that costs $5,000 will produce annual cash flows of $3,000 for 3 years. Using a required return of 8%, the investment will generate a NPV of $
Answers
Answer:
The investment will generate a NPV of $2,731.
Step-by-step explanation:
Cost of an investment (PV) = $5,000
Annual cash flows = $3,000
Period of investment = 3 years
Interest rate of return = 8%
Annuity Factor = 2.577 (for 3 years at 8% per year)
Present value of the annuity = $3,000 * 2.577 = $7,731
NPV = Annuity PV minus PV of investment cost
= $7,731 - $5,000
= $2,731
b) The NPV (net present value) of $2,731 is the difference between the present value of the annual cash flows $7,731 and the investment cost of $5,000. The resulting NPV is positive and the investment should be accepted.

explain how to determine if the two expressions are equivalent using x=6 and x=10
8x+40. 8(x+5)
Answers
Answer:
Step-by-step explanation:
if they're equivalent, when you plug in either 10 or 6 for x, they should both equal the same.
x=10, 8(10)+40=120.... 8(10+5)=120. so they equal. also test 6
8(6)+40=88. 8(6+5)=88
they are equivalent since they both equal each other, no matter what you plug in. reason being that the 8(x+5) is the factorized version of 8x+40
Answer:
By putting both values of x in the expression, it can be concluded that both expressions are equivalent.
Step-by-step explanation:
The expressions can be evaluated to be equivalent by putting the values given
The expressions are:
8x+40 and 8(x+5)
Putting x = 6 in both
[tex]8x+40\ and\ 8(x+5)\\8(6)+40\ \ ; \ 8(5+6)\\48+40\ \ \ \ ; \ \ 8(11)\\88\ \ \ \ \ \ \ \ \ \ \ ; \ \ 88[/tex]
The values of both expressions are same on x=6
Now putting x = 10
[tex]8x+40\ and\ 8(x+5)\\8(10)+40\ \ ; \ 8(10+6)\\80+40\ \ \ \ ; \ \ 8(16)\\120\ \ \ \ \ \ \ \ \ ; \ \ 120[/tex]
The values of both expressions are same on x = 10
Hence,
By putting both values of x in the expression, it can be concluded that both expressions are equivalent.
