the operation * is defined on the set R of all real number by 2a +3b ÷ a +b evaluate 2*(3*4)
9514 1404 393
Answer:
2*(3*4) = 41/16
Step-by-step explanation:
Your function is not carefully defined.* We assume you intend ...
f(a, b) = (2a +3b)/(a +b)
and you want to find ...
f(2, f(3, 4))
__
Filling in the values and doing the arithmetic, we have ...
[tex]2*(3*4)=\dfrac{2\cdot2+3\cdot\dfrac{2\cdot3+3\cdot4}{3+4}}{2+\dfrac{2\cdot3+3\cdot4}{3+4}}=\dfrac{4+3\cdot\dfrac{18}{7}}{2+\dfrac{18}{7}}\\\\=\dfrac{4\cdot7+3\cdot18}{2\cdot7+18}=\dfrac{82}{32}=\boxed{\dfrac{41}{16}}[/tex]
_____
* We have assumed that the definition is describing the result of using the infix operator * in an expression of the form a*b. We have also assumed that your use of the ÷ symbol means ...
a*b ≡ (2a+3b)/(a+b)
as opposed to the strict Order of Operations interpretation ...
a*b ≡ 2a + (3b/a) +b

Answer:
B
Step-by-step explanation:
√16/25 = 4/5 = 0.8-> (4/5 x 4/5 = 16/25)
(2/5)^3 = 8/125 = 0.064
-(-0.3)^3 = 0.027 (an odd exponent mantains the same sign of the number and minus x minus = +)
-√169 = -13
-13 is a negative number so it is surely the smallest
2 is minor than 6 so we have that 0.027 is minor than 0.064
8 is major than 0, so 0.8 is the greatest number
we have
-√169 ; -(-0.3)^3 ; (2/5)^3 ; √16/25

The movement of moving particles is described in the equation r=ht22 −2vt−2c. Solve the equation for v.
Pls help
Answer:
[tex]v=\dfrac{r-ht^2+2c}{-2t}[/tex]
Step-by-step explanation:
The given equation is :
[tex]r=ht^2 -2vt-2c[/tex]
We need to solve the above equation for v.
Subtract ht² from both sides.
r-ht²= ht²-2vt-2c-ht²
r-ht² = -2vt-2c
Adding 2c both sides,
r-ht² +2c= -2vt-2c+2c
r-ht² +2c = -2vt
Dividing both sides by (-2t)
[tex]v=\dfrac{r-ht^2+2c}{-2t}[/tex]
So, the value of v is equal to [tex]\dfrac{r-ht^2+2c}{-2t}[/tex].

Answer:
The answer is D
Step-by-step explanation:
Because both when we multiply we will get the same answer
Answer:
It would be B. 8x3/5
Step-by-step explanation:
So when multiplying fractions, you multiply the denominator of one fraction by the denominator of the other. You then multiply the numerator of one fraction by the numerator of the other.
The 8, can be turned into fraction form by thinking of it as 8/1 x 3/5.
And thinking about how we do denominator x denominator, numerator x numerator, it will look like:
[tex]\frac{8*3}{1*5}[/tex]
There is one more thing we need to simplfy before we will get our answer.
When you multiply a number by 1, what do you get? The same exact number as before.
Sp tecnically, 1*5 would just be 5:
[tex]\frac{8*3}{5}[/tex]
This looks like answer b!
Hope this helps!

What is the measure of x.
Answer:
x=140°
Step-by-step explanation:
the 40° angle and x are supplementary, so:
x=180°-40°
x=140°
7) what is the approximate value of x? (Hint: there are two right angle triangles here, round to the nearest tenth)
Answer:
x= 8.2
Step-by-step explanation:
first we need to find the hypotenuse of the smaller triangle
3² + 4² = C
9 + 16 = 25
√25 = 5
now that we found the hypotenuse of the smaller triangle then we now find the hypotenuse of the larger one (x)
6.5² + 5² = C
42.25 + 25 = 67.25
√67.25 = 8.2
Wally blew 1/4 of his income last week on video

income last week?
games and
Answer:
(hope this is right)
$224
Step-by-step explanation:
If he spent 1/4 on video games and 1/8 on food then Wally spent 3/8 of his income.
84 divided by 3 is 28
28 times 8 would be 224 dollars total of his income.

A bookstore costs $75 a day to keep open, and spends $10 for each book it
sells. The store charges $15 for each book it sells. If n represents the number
of books sold, which equation represents the revenue function for this
bookstore?
A. r= 15n
B. r= 25n
C. r= 10n
D. r= 75n
Answer: A. r= 15n
Step-by-step explanation: took the quiz.
The solution is, The cost function of this bookstore is 10n + 75.
What is cost function?A cost function is a formula used to predict the cost that will be experienced at a certain activity level.
here, we have,
According to the given problem,
Cost to open bookstore for a day - $75
Price for selling each book = 10
Considering number of books to be n,
Total cost for selling each book = $(10×n)
Therefore total cost price = $( 10n + 75)
Hence, we can conclude that the total cost function of this bookstore is represented by equation 10n + 75

A specific laptop loses half of its value every six months. If the original cost was $1, 100 and the value of the laptop is now $68.75, how many years have you owned the laptop
Answer:
2 years! :)
Step-by-step explanation:
At a store, 7 out of the first 10 people who entered were
carrying a purse. Based on this information, if 250
people enter that store in one day, how many people
could be expected to be carrying a purse?
175/250 or %70
Hope this answers your question!
Answer:
175 people would be expected to be carrying a purse.
Step-by-step explanation:
7/10 people who entered were carrying a purse and if you say 250 people entered the store in one day the number of people would now be 250 instead of 10.
Since I made it into a fraction form you would need to find a numerator that would make the ratio equal. 7/10 = ?/250 Since 10 is a factor of 250 you would divide 250 by 10 and you would get 25. Since 10 * 25 is 250 you would also multiply the numerator, which is 7, by 25. 7 * 25 is 175. The ratio 7/10 = 175/250 is now equal.
The answer would be 175 would be expected to be carrying a purse since I had made the numerator of the fraction the number of people who were expected to bring a purse and the denominator the number of people entering the store.

Answer:
x = 56°

1) Base of an isosceles triangle is five more than three times the equal sides and perimeter of the triangle is 75 cm. Find the lengths of the sides of the triangle.
Answer:
Equal sides of triangle = 14 cm
Base of an isosceles triangle = 47 cm
Step-by-step explanation:
Given:
Perimeter of the triangle = 75 cm
Base of an isosceles triangle = five more than three times the equal side
Find:
Lengths of isosceles triangle
Computation:
Assume;
Equal sides of triangle = a
So,
Base of an isosceles triangle = 3a + 5
Perimeter of the triangle = Base of an isosceles triangle + 2[Equal sides of triangle]
Perimeter of the triangle = 3a + 5 + 2[a]
Perimeter of the triangle = 5a + 5
75 = 5a + 5
5a = 70
a = 14
Equal sides of triangle = 14 cm
Base of an isosceles triangle = 3a + 5
Base of an isosceles triangle = 3(14) + 5
Base of an isosceles triangle = 42 + 5
Base of an isosceles triangle = 47 cm
