Four different positive integers are to be chosen so that they have a mean of 2017.

What is the smallest possible range of the chosen integers?

Answers

The smallest possible range of the chosen integers is; 2015

What is the smallest possible Integer?

First of all, the range of a set of numbers is the difference between the largest and smallest numbers in the set.

The smallest range of a set of four different positive integers is 3. This occurs when the integers are consecutive, and only in this case. We first show that we cannot have four consecutive integers

with a mean of 2017.

Assume, to the contrary, that n is a positive integer such that the consecutive integers n, n + 1, n + 2 and n + 3 have 2017 as their mean.

Thus;

[n + n + 1 + n + 2 + n + 3]/4 = 2017

4n + 6 = 2017 * 4

n = 2015.5

Since n is an integer, then this can't be true. However, with a little tweaking of this, we can tell that we can use 2015 as our least integer.

A trail mix recipe calls for 1 cup of nuts for every 2 cups of granola. If you want to make 12 cups of trail mix, how many cups of granola will you need? Use a tape diagram to help organize your thinking.(1 point)
cups.

PLEASE HELP ITS DUE IN 30 MINUTES!! IM GIVING TEN POINTS AWAY

Answers

Answer:

  8 cups

Step-by-step explanation:

Given a recipe for trail mix that calls for 1 cup of nuts for each 2 cups of granola, you want to know the number of cups of granola required for 12 cups of trail mix.

Fraction

The fraction of the total volume of trail mix that is granola is ...

  granola / (trail mix) = granola / (nuts + granola)

  (2 cups)/(1 cup +2 cups) = 2/3

Applied to the quantity 12 cups of trail mix, we find the volume of granola to be ...

  granola = (2/3)×(12 cups) = 8 cups

You need 8 cups of granola for 12 cups of trail mix.

1/4 of a certain number is removed from two fifth of that number if the result is 3 find the number ​

Answers

Answer:

2/5--1/4=3

Step-by-step explanation:

lcm is 20 =8-5=3/20=3 =20

Answer is N = 20

Step by step

1/4 of a number means 1/4n
Is removed from is subtract
2/5 of that number means 2/5n
Result is 3 means equal = 3

Put this into an equation

2/5n - 1/4n = 3

Our common denominator is 20

2/5 = 8/20 ( multiplying top and bottom by 4)
1/4 = 5/20 (multiply top and bottom by 5)

8/20n - 5/20n = 3

Subtract

3/20n = 3

Divide both sides by 3/20 to solve for n
When we divide fractions we flip the divisor and multiply

3/20 * 20/3 n = 3 * 20/3

Multiply

n = 20

given that 133 base n = 43base 10, find the value of n​

Answers

Answer:

n = 5

Step-by-step explanation:

Any 3-digit number to the base n will have its rightmost digit have a place value of n⁰, its next rightmost digit a place value of n¹ and the leftmost digit will have a place value of n²

This means 133can be represented as follows
n²     n¹     n⁰

1       3      3

The actual value in terms of a base of 10

= 3 x n⁰ + 3  x n¹   + 1 x n²

= 3 x 1 + 3 x n + 1 x n²      (n⁰ = 1 and n¹ = n)

= 3 + 3n + 1n²

Since we are given the information that 133ₙ = 43₁₀
3 + 3n + 1n²  = 43

subtract 3 from both sides
3n + 1n² = 40

Rewrite as

n² + 3n = 40

Factoring n on the left side=>
n(n + 3) = 40

If we look at the factors of 40:
1 x 40

2 x 20

4 x 10

5 x  8

5 and 8 satisfy the condition n(n + 3) = 40

So n = 5

The remaining number of socks S a store has is modeled
by S(p) = 14 - 2p, where p is the number of pairs of
socks sold.
A. What do S(0) and S(6) represent?

Answers

Considering the numeric values of the function, we have that:

a) S(0) represents the remaining number of socks after 0 pairs are sold, and S(6) represents the remaining number of socks after 6 pairs are sold.

b) S(0) = 14, S(6) = 12.

c) The domain is not all real numbers, as the remaining number of socks cannot be negative, hence the domain is of 0 ≤ p ≤ 7.

How to find the numeric value of a function or of an expression?

To find the numeric value of a function, we replace each instance of the variable in the function by the desired value.

For this problem, the function is given as follows:

S(p) = 14 - 2p.

In which S(p) is the remaining number of socks after p socks are sold.

Then the numeric values are:

S(0) = 14 - 2(0) = 14.S(6) = 14 - 2(6) = 2.

The domain of a function is the set that contains all possible input values of the function. The remaining number of socks cannot be negative, hence the domain is of 0 ≤ p ≤ 7, and the graph is given at the end of the answer.

Neil puts 1500 pounds in the bank,at a rate of 3% compound interest.
Jerry puts 1500 pounds in the bank at a rate of r % simple interest.


After 5 years they have the same amount.

Find r

Answers

When Jerry puts 1500 pounds in the bank for 5 years then the rate of interest which makes the amount equal for Jerry and Neil is 1.85%.

Given Neil puts 1550 pounds in the bank, at a rate of 3% compound interest.

we need to calculate the total amount and interest at the end of 5 years.

P=1500 pounds

r = 3%

n = 5 years.

A = P(1+r/100)ⁿ

A = 1500(1+3/100)⁵

A = 1500(103/100)⁵

A = 1500 × 103/100 × 103/100 × 103/100

A = 3278181/2000

A = 1639.09

C.I = A-P

= 1639.09 - 1500

= 139.09

From the question, After 5 years they have the same amount.

Therefore we use the amount to calculate rate of interest as :

A = 1639.09

Simple interest = 1639.09 - 1500

= 139.09

Therefore, P = 1500

I = 139.09

t = 5 yrs

R = (100×I)/(P×t)

R = (100×139.09)/(1500×5)

R = 1.85%

Hence the rate of interest is 1.85%.

the sides of a right-angled triangle are related like 3 : 7 and the height drawn on the hypotenuse is 42cm. calculate the projections of the sides on the hypotenuse

Answers

The 3 : 7 ratio of the leg lengths and the 42 cm length of the hypotenuse side using Pythagorean theorem, gives the lengths of the sides (the legs of the right triangle) as follows;

[tex]147 \cdot \sqrt{ \frac{2}{29} } [/tex] and [tex] 63 \cdot \sqrt{ \frac{2}{29} }[/tex]

What is Pythagorean theorem?

Pythagorean theorem states the square that has the hypotenuse of a right triangle as its side length is equal in area to the sum of the areas of the two squares formed by legs of the right triangle.

Given;

The possible given parameters are;

The ratio of the length of the sides (the legs) of the triangle is 3 : 7

The length of the hypotenuse side = 42 cm

Required: The lengths of the other two sides of the triangle

Solution;

The lengths of the two sides are found as follows;

Let a and b represent the lengths of the legs of the right triangle, according to Pythagorean theorem, we have;

a² + b² = 42²

The ratio of the leg lengths gives;

a/b = 3/7

Therefore;

a = (3/7)•b

Which gives;

((3/7)•b)² + b² = 42²

b²•((3/7)² + 1) = 42²

b = 42²/(((3/7)² + 1)) = 42²×(58/49)

[tex]b = 147 \cdot \sqrt{ \frac{2}{29} } [/tex]

Which gives;

[tex]a =\frac{3}{7} \times 147 \cdot \sqrt{ \frac{2}{29} }= 63 \cdot \sqrt{ \frac{2}{29} }[/tex]

The normal price of a computer game is £40
The price is reduced by 1/5 in a sale.
Work out the price of the computer game in the sale.

Answers

Answer:

£32

Explanation:

so 1/5 = 0.2

to make 0.2 a percent just multiply by 100 so 0.2 • 100 = 20%

so the discount would be 20%, meaning the game holds 80% of its value since

100-20 = 80

so to make 80% a decimal, divide by 100 so 80/100 = 0.8

so then you just multiply: 40 • 0.8 = 32

so the game is £32

hope this helps :)

The price of the computer game on sale is  £32.

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, The normal price of a computer game is £40.

The price is reduced by 1/5 in a sale.

∴ The price of the computer game on discount can be obtained if we subtract the fraction of the discount times the normal price from the normal price which is,

= {(40 - (1/5)×40}.
