Answer:

B. 88.8

Step-by-step explanation:

let x represent class y

(x+71.2)/2=80   multiply each side by 2

x+71.2=160      subtract 71.2 by both sides

x=88.8

or

trial an error

replace x with each of the numbers and see if it plugs in.

example:

(80.5+71.2)/2=80

151.7/2=80

75.85=80?

false. incorrect

another example:

(88.8+71.2)/2=80

160/2=80

80=80?

true. correct

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:

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!

Answer:

1/132

Step-by-step explanation:

1/3 ÷ 44 would be solved by multiplying 1/3 and 1/44 which is 1/132

Answer:

b

Step-by-step explanation:

There are 2 sequences with a₁ = 47, b and d

The common difference of both is

(b)

d = a₂ - a1 = 29 - 47 = - 18

(d)

d = a₂ - a₁ = 65 - 47 = 18

The the sequence with first term 45 and common difference - 18 is b

The required sequence which has a first term equal to 47 and a common difference of -18 is {47, 29, 11, -7, …}. Option B is correct.

Arithmetic progression is the series of numbers that have common differences between adjacent values

Geometric progression is a sequence of series whose ratio with adjacent values remains the same.

Here,
An arithmetic sequence has a first term equal to 47 and a common difference of -18,
a = 47
d = -18

The sequence formed given as,
⇒ a, a + d, a + 2d, a + 3d
⇒ 47, 47 - 18, 47 + 2(-18), 47 + 3(-18)
⇒ 47 , 29, 11, -7 . . . . .

Thus, the above sequence matches the sequence given in option b.

Answer: A. r= 15n

Step-by-step explanation: took the quiz.

The solution is, The cost function of this bookstore is 10n + 75.

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

Answer:

El precio de la falda es 50 €.

Step-by-step explanation:

Lo que sabemos:

[tex] F = 5 + B [/tex]   (1)

En donde F es por falda y B por blusa.

Si compras 6 faldas y 4 blusas y pagas 480 €:

[tex] 6F + 4B = 480 [/tex]  (2)

Entonces, al introducir la ecuación (1) en (2) podemos hallar el precio de cada falda.

[tex] 6F + 4B = 480 [/tex]

[tex]6(5 + B) + 4B = 480[/tex]

[tex] 10B = 480 - 30 [/tex]

[tex]B = \frac{450}{10} = 45[/tex]  

Finalmente, el precio de la falda se puede encontar con la ecuación (1):

[tex]F = 5 + 45 = 50[/tex]

Por lo tanto, el precio de la falda es 50 €.

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

Step-by-step explanation:

first we need to find the hypotenuse of the smaller triangle

3² + 4² = C

√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

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

Step-by-step explanation:

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].
