Janet bought same bars of choclate to share equally with her friends. she bought between 35 and 50 bars altogether. if she shares the bars of chocolate equally with 7 friends, she will have 7 bars left over. If she shares the bars equally with 6 friends she will have 5 bars left over. How many bars of chocolate did she buy?
a.47
b.45
c.46
d.48

Answers

Its letter d.48 hope i helped you , but im not sure..

For the conditions to be fulfilled number of chocolate bars Janet bought is 35.

What is an equation?

An equation is a statement in form of numbers and variables that both sides are equal.

Janet bought the same bars of chocolate to share equally with her friends and it is between 36 and 50.

There are two possible cases,

Let the number of chocolates be 'N' and no. of chocolates each friend gets be 'A'.

(i)  If she shares the bars of chocolate equally with 7 friends, she will have 7 bars left over,

∴ N = 7A + 7...(i).

(ii) If she shares the bars equally with 6 friends she will have 5 bars left over,

Let the number of chocolates be 'N' and no. of chocolates each friend gets be 'B'.

∴ N = 6B + 5...(ii)

Now, we have to equate these two equations,

7A + 7 = 6B + 5.

7A = 6B - 2.

A = (6B - 2)/7.

From here we have to find such integer value of B which also makes the value of A an integer and also when we put the values of either A or B in our equations it should lie between 35 and 50.

So,

A = (6B - 2)/7.

When B = 5 then A = 4. Or when B = 12 the A = 10.

But the B = 12 and A = 10 is inadmissible.

Now, we'll put the value of A or B in eqn (i) or (ii).

Which results in N = 35.

So, the number of chocolate bars she bought is 35.

The results of a recent survey indicate that the average new car costs $23,000 with a standard deviation on $3,500. The prices of the car are normally distributed. a. If someone buys a car for $32,000, what proportion of cars cost an equal amount or more than this? b. If someone buys a car for $16,000, what proportion of cars cost an equal amount or more than this?

Answers

Answer:

(a) 0.0051

(b) 0.9773

Step-by-step explanation:

Let X = prices of the car.

It is provided that [tex]X\sim N(23,000, 3,500^{2})[/tex].

(a)

Compute the value of P (X ≥ 32000) as follows:

[tex]P(X\geq 32000)=P(\frac{X-\mu}{\sigma}>\frac{32000-23000}{3500})[/tex]

                       [tex]=P(Z>2.57)\\=1-P(Z<2.57)\\=1-0.99492\\=0.00508\\\approx 0.0051[/tex]

Thus, the proportion of cars cost an equal amount or more than $32,000 is 0.0051.

(b)

Compute the value of P (X ≥ 16000) as follows:

[tex]P(X\geq 16000)=P(\frac{X-\mu}{\sigma}>\frac{16000-23000}{3500})[/tex]

                       [tex]=P(Z>-2)\\=P(Z<2)\\=0.97725\\\approx 0.9773[/tex]

Thus, the proportion of cars cost an equal amount or more than $16,000 is 0.9773.

what is bigger 3.14 or 3.1 repeating

Answers

Answer:

3.14

Step-by-step explanation:

compare 3.4 to 3.111111111111111111...

4 is bigger than 1

3.14 is bigger than 3.1 repeating.

The number 3.1 repeating (or 3.1 with an infinite number of decimal places of 1) is equivalent to the mathematical concept of the number 3.1111..., where the digit 1 repeats indefinitely.

When comparing 3.14 and 3.1 repeating, we can consider the decimal places:

3.14 has a hundredth place digit of 4, which is greater than the repeating decimal of 3.1, where the hundredth place digit is 1.

Therefore, 3.14 is bigger than 3.1 repeating.

Hayley and Maxwell are jogging on a track. Hayley jogs 3/4 mile in 1/6 hour. Maxwell jogs 2/3 mile in 2/15 hour. Who is faster?

Answers

Maxwell runs faster than Hayley

In order to determine who runs faster, the average speed has to be determined

Average speed is total distance travelled divided by total time travelled.

Average speed = Total distance / Total time

Hayley's average speed = [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{1}{6}[/tex]

=  [tex]\frac{3}{4}[/tex] x 6 = [tex]\frac{9}{2} = 4\frac{1}{2}[/tex] miles / hour

Maxwell's average speed = [tex]\frac{2}{3}[/tex] ÷ [tex]\frac{2}{15}[/tex]

[tex]\frac{2}{3}[/tex] x [tex]\frac{15}{2}[/tex] = 5 miles / hour

Maxwell runs faster because he has a higher average speed when compared with Hayley

Forman1911THE MATCHPLESE HELP WITH IT !!There never was a time when the world was without fire, but there was a time when men did not know how to kindle fire; and after they learned how to kindle one, it was a long, long time before they learned how to kindle one easily. In these days we can kindle a fire without any trouble, because we can easily get a match; but we must remember that the match is one of the most wonderful things in the world, and that it took men thousands of years to learn how to make one. Let us learn the history of this familiar little object, the match.Fire was first given to man by nature itself. When a forest is set on fire by cinders from a neighboring volcano, or when a tree is set ablaze by a thunderbolt, we may say that nature strikes a match. In the early history of the world, nature had to kindle all the fires, for man by his own effort was unable to produce a spark. The first method, then, of getting fire for use was to light sticks of wood at a flame kindled by natureby a volcano, perhaps, or by a stroke of lightning. These firebrands were carried to the home and used in kindling the fires there. The fire secured in this way was carefully guarded and was kept burning as long as possible. But the flame, however faithfully watched, would sometimes be extinguished. A sudden gust of wind or a sudden shower would put it out. Then a new firebrand would have to be secured, and this often meant a long journey and a deal of trouble.In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. The druggist had discovered the first friction-chemical match, the kind we use to-day. It is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. Although Walker's match did not require the bottle of acid, nevertheless it was not a good one. It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. In a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. The match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This was the phosphorus match, the match with which we are so familiar.please help with it.What is the main idea of the second paragraph Which land feature is formed by two oceanic tectonic plates diverging? *mid-ocean ridgevolcanic island arccontinental volcanoescontinental mountain range Channing Corporation makes two products (A1 and B2) that require direct materials, direct labor, and overhead.
