Answers

Answer 1

Answer:

Rs. 83.33

Step-by-step explanation:

cost of a pen = Total cost / total quantity

= 100/10

= Rs. 8.33/pen

Total cost for 10 pens = Cost per pen x quantity

= Rs.8.33 x 10

= Rs. 83.33 Ans

On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled in miles, d, to the number of hours flying, t, is . How long will it take the airplane to travel 800 miles? Do not include units (hours) in your answer.

Answers

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question

On a flight New York to London an airplane travels at a constant speed. An equation relating the distance traveled in miles d to the number of hours flying t is t= 1/500d. How long will it take the airplane to travel 800 miles?

Speed is the change in distance if a body with respect to time. It is expressed mathematically according to the question as t = 1/500 × d

To determine the time it will take to travel 800miles, we will substitute d = 800 into the modeled equation.

t = 1/500 × 800

t = 800/500

t = 8/5

t = 1.6

Answer: She can make 12 batches of brownies. There is a slight remainder, but think about it like this, if you only had a spoon full of sugar left, do you think you could make an entire batch of brownies? No. So if you see problems like this, the whole number should be the answer (unless asked otherwise).

Step-by-step explanation:  Since 3/4 is like 75 out of 100, the decimal form is .75 and we all know (or should know) that 1/2 can be put as .5. Whenever there's a whole number before the fraction, and you want to convert the fraction into a decimal, the whole number will go before the decimal. So after converting the fractions to decimals, the problem is 9.5 divided by .75 which is 12.6. Like I said before, that remainder .6 can't make an entire batch of brownies, so we just go with the whole number 12.

what is the factor of 6a2 – 19a + 10 ???

Answers

Answer:

(2a - 5) • (3a - 2)

step by step explanation:

Step-1 : Multiply the coefficient of the first term by the constant 6 • 10 = 60

Step-2 : Find two factors of 60 whose sum equals the coefficient of the middle term, which is -19 .

-60 + -1 = -61

-30 + -2 = -32

-20 + -3 = -23

-15 + -4 = -19 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -15 and -4

6a2 - 15a - 4a - 10

Step-4 : Add up the first 2 terms, pulling out like factors :

3a • (2a-5)

Add up the last 2 terms, pulling out common factors :

2 • (2a-5)

Step-5 : Add up the four terms of step 4 :

(3a-2) • (2a-5)

Which is the desired factorization

Final result :

(2a - 5) • (3a - 2)

Answer:

(2a-5) (3a-2) is your correct answer.

Solve -1/6 (3x – 9) – 9= 3.

The solution is x=

Please explain

Answers

Answer:

x=23

Step-by-step explanation:

1/6 as a decimal is 0.16666667 but i rounded it to 0.2

so the equation is the 0.2(3x-9)-9=3

then i did 0.2 times 3x =0.6x

then 0.2 times -9= -1.8

so the equation now looks like this:

0.6x-1.8x-9=3

so i add 1.8 and 9 to 3 which gives you 13.8

then the equation looks like this:

0.6x=13.8

then you do 13.8 divided by 0.6 which equals 23.

Do these pairs of values (x and y) represent two quantities that are
proportional?
A. Yes, because as x increases, y increases.
B. No, because not all of the pairs represent the same ratio.
C. Yes, because the ratios į and i are equal.
O D. No, because not all of the pairs are simplified ratios.

Answers

Answer: B) No, because not all of the pairs represent the same ratio

For each row, divide y over x

Row 1:  y/x = 5/3 = 1.67 approximately

Row 2: y/x = 7.4 = 1.75

Row 3: y/x = 10/6 = 1.67 approximately

Row 4: y/x = 15/9 = 1.67 approximately

We see that row 2 has a ratio different from the others. If we were able to ignore this row, then the answer would be "yes x and y are proportional". However, we cannot ignore this row so that's why the answer is choice B.

We want to see if the relationship between x and y is proportional or not.

We will see that the correct option is B:

"No, because not all of the pairs represent the same ratio."

Let's see how to solve this.

First, a proportional relationship is something of the form:

y = k*x

Where k is the constant of proportionality.

So to see if the relationship between x and y is proportional, we can input the pairs on the general proportional relationship.

For the first pair, we have x = 3 and y = 5, then:

5 = k*3

Now we can find the value of k:

k = 5/3 = 1.667

Now let's do the same for the second pair of points, we should get the same constant of proportionality.

7 = k*4

k = 7/4 = 1.75

So we got different constants of proportionality for two different x-y pairs, thus, the relationship is not proportional.

Because k is defined as the ratio between y and x, we can say that the relationship is not proportional because not all of the pairs represent the same ratio.

Thus the correct option is B.

How many hours of tutoring will occur before the fees are the same?
How much has each person been paid in tutoring fees?

Answers

Answer:

after 2 hours, they will have the same fee.

they will have been payed 11$

Step-by-step explanation:

if you say  h = hours of tutoring,

Rakim charges 7 + 2h

Joan charges 3 + 4h

since you want them to be the same, you can write the following equation:

7 + 2h = 3 + 4h

subtract 2h from each side

7 = 3 + 2h

subtract 3 from each side

4 = 2h

divide both sides by 2.

h = 2

after 2 hours, they will have the same fee.

they will have been payed 11$
