Solve:
12 + 5 + 3’2 x 10 - 5 =
(12 + 5) + 3'2 x (10 – 5) =

Answers

Answer 1

Answer:

1) 102

2) 62

Step-by-step explanation:

12 + 5 + 3² × 10 - 5

12 + 5 + 9 × 10 - 5

12 + 5 + 90 - 5

17 + 90 - 5

107 - 5

102

(12+5) + 3² × (10 - 5)

(17) + 9 × (5)

17 + 45

Answer 2

Hi :)

12 + 5 + 3^2 x 10 - 5 = 102

(12 + 5)+ 3^2 x (10 - 5) = 62

12 + 5 + 3^2 x 10 - 5

Add 12 and 5 to get 17
17 + 3^2 × 10−5

Calculate 3 to the power of 2 and get 9
17 + 9 × 10 − 5

Multiply 9 and 10 to get 90
17 + 90 − 5

Add 17 and 90 to get 107
107−5

Subtract 5 from 107 to get 102

(12 + 5)+ 3^2 x (10 - 5)

Add 12 and 5 to get 17
17 + 3^2 x (10 - 5)

Calculate 3 to the power of 2 and get 9
17 + 9 x (10−5)

Subtract 5 from 10 to get 5
17+ 9 × 5

Multiply 9 and 5 to get 45
17+45

Add 17 and 45 to get 62.

Hope this helps :)

A bag contains 120 marbles. Some are red the rest are black. There are 19 red marbles for every black marble. How many red marbles are in the bag?

Answers

Answer:

114

Step-by-step explanation:

Ratio of red marbles to black marbles is 19:1. (Data from 3rd sentence)

19+1= 20

20 units= 120 (Data from 1st sentence)

1 unit= 120/20= 6

19 units= 120-6= 114 (Values solved in working above)

Ans: There are 114 red marbles.

Step-by-step explanation:

In his motorboat, Bill Ruhberg travels upstream at top speed to his favorite fishing spot, a distance of 264 mi, in 6 hr. Returning, he finds that the trip downstream, still at top speed, takes only 5.5 hr. Find the rate of Bill's boat and the speed of the current. Let x = the rate of the boat in still water and y = the rate of the current.

Answers

Answer:

The values are [tex]x = 46 miles /hr [/tex]

[tex]y = 4 \ miles / hr[/tex]

Step-by-step explanation:

From the question we are told that

The distance covered is d = 264 miles

The time taken is [tex]t_1 = 6 hours[/tex]

The time taken for the return trip is [tex]t_2 = 5.5 \ hours[/tex]

Generally during the trip toward fishing spot , the velocity is mathematically represented as

[tex]v_t = \frac{d}{t_1 } = x - y[/tex]

=> [tex]v_t = \frac{264}{6 } = x - y[/tex]

=> [tex]x - y = 44 \cdots 1 [/tex]

Generally during the return trip , the velocity is mathematically represented as

[tex]v_r = \frac{d}{t_2} = x+ y[/tex]

=> [tex]v_r = \frac{264}{5.5} = x+ y[/tex]

=> [tex]48 = x+ y\cdots 2[/tex]

add equation 1 and 2

[tex]2x = 92[/tex]

=> [tex]x = 46 miles /hr [/tex]

substituting this into equation 1

[tex] 46 - y = 44 \cdots 1 [/tex]

=> [tex]y = 4 \ miles / hr[/tex]

The equation for line w is y = 2x – 3. Line d contains the point (4, -1) and is parallel to line w. Which equation
describes line d?

Answers

Answer:

y = 2x - 7

Step-by-step explanation:

y = 2x - 3

Gradient of line w = 2

Gradient of line d = 2

i.e line w and d are parallel.

Equation of line d is:

y - (-1) = 2(x - 4)

y + 1 = 2x - 8

y = 2x - 7

What is mean by Function?

A function is a relation in which each element of the domain, or x-value, is mapped to one element of the range, or y-value. This means that no x can be mapped to more than one y, so if we have the same number used twice for x, we do not have a function.

Now, For given function is,

This means that 5 cannot be used for x in the other ordered pair.

Since there is no restriction on y in order to be a function, y can be any real number.

Thus, The correct answer is:

⇒ Any real number for x except 5, and any real number for y.

Which equation shows a proportional relationship between x and y?

y = 16

y = 7x

y=−7x−2

y = 9x + 1

Answers

The equation that shows a proportional relationship is y = 7x.

How to find the equation that is proportional?

Two variables have a proportional relationship if all the ratios of the variables are equivalent.

In other words, a proportional relationship is one in which two quantities vary directly with each other.

Therefore, a proportional relationship can be represented as y = kx.

where

k = constant of proportionalitythe variables are x and y

Therefore, y varies directly as x in a proportional relationship.

Hence, the equation that shows proportional relationship is y = 7x as 7 is the constant of proportionality. y and x are the variables.

Penelope and the Suitors from Book II of The Odyssey by Homer "Telemachus, insolent braggart that you are, how dare you try to throw the blame upon us suitors? It is your mother's fault not ours, for she is a very artful woman. This three years past, and close on four, she had been driving us out of our minds, by encouraging each one of us, and sending him messages without meaning one word of what she says. And then there was that other trick she played us. She set up a great tambour frame in her room, and began to work on an enormous piece of fine needlework. 'Sweet hearts,' said she, 'Ulysses is indeed dead, still do not press me to marry again immediately, waitfor I would not have skill in needlework perish unrecordedtill I have completed a pall for the hero Laertes, to be in readiness against the time when death shall take him. He is very rich, and the women of the place will talk if he is laid out without a pall.' "This was what she said, and we assented; whereon we could see her working on her great web all day long, but at night she would unpick the stitches again by torchlight. She fooled us in this way for three years and we never found her out, but as time wore on and she was now in her fourth year, one of her maids who knew what she was doing told us, and we caught her in the act of undoing her work, so she had to finish it whether she would or no. The suitors, therefore, make you this answer, that both you and the Achaeans may understand'Send your mother away, and bid her marry the man of her own and of her father's choice'; for I do not know what will happen if she goes on plaguing us much longer with the airs she gives herself on the score of the accomplishments Minerva has taught her, and because she is so clever. We never yet heard of such a woman; we know all about Tyro, Alcmena, Mycene, and the famous women of old, but they were nothing to your mother any one of them. It was not fair of her to treat us in that way, and as long as she continues in the mind with which heaven has now endowed her, so long shall we go on eating up your estate; and I do not see why she should change, for she gets all the honour and glory, and it is you who pay for it, not she. Understand, then, that we will not go back to our lands, neither here nor elsewhere, till she has made her choice and married some one or other of us." 2 Select the correct answer. Which detail is present in the painting but not in the passage itself? A. The suitors are kind and romantic, eager to win Penelope's heart. B.
