Answer:

  4. m = 3, n = 7

  5. a) 2.0272; b) 72.4; c) 372

Step-by-step explanation:

4. 56 = 8×7 = 2^3 × 7

Comparing to 2^m × n, we see that m=3, n=7.

5. It's all about scale factors. One way to work this problem is to write all of the numbers in terms of the numbers of the original "given."

a) 0.724 × 2.8 = (724×10^-3) × (28×10^-1) = 20272×10^-4

  0.724 × 2.8 = 2.0272

__

b) 202.72 ÷ 2.8 = (20272×10^-2) ÷ (28×10^-1) = 724×10^(-2-(-1)) = 72.4

  202.72 ÷ 2.8 = 72.4

__

c) 20272 ÷ 56 = (20272 ÷ 28) ÷ 2 = 724 ÷ 2 = 362

  20272 ÷ 56 = 372

Answer:

4, 5, 6

Step-by-step explanation:

The only three consecutive positive integers that fits the criteria is 4, 5, and 6 since the product of the two larger integers, 5 and 6, is 30 and 4, 5, 6 is consecutive.

Answer:

n = 7

Step-by-step explanation:

3 = 10 - n

-10   -10              subtract 10 from both sides

---------------

-7 = -n                -n is the same as -1n so let's divide both sides by -1

/-1    /-1

Answer:

[tex]a_n=9n+5[/tex]

Explanation:

[tex]a_n=9n+5[/tex] will find any term in the sequence, just replace "n" with the term you want.

Example:

If you wanted to find the 9th term, replace [tex]a_n[/tex] with [tex]a_9[/tex], and you'll get

[tex]a_9=86[/tex]

86 is the 9nth term.

Answer:

No; Because 9 is a factor of 4554. By divisibility rules sum of digits of 4554 is 18, which is a number divisible by 9. Hence 4554 is divisible by 9.

Answer:

Option A.

Step-by-step explanation:

A rational number is a number that can be expressed in a fraction (ratio of integers).

Option A is rational since both quantity are rational

Option B is irrational since

[tex]\sqrt{3}\cdot\sqrt{9}=\sqrt{27}[/tex]

where 27 is not a square of any fractions/ integers. Hence, it cannot be expressed as a fraction and is irrational.

Option C is irrational. Note that PI is irrational. Any rational multiples of an irrational number must also be irrational.

Option D is irrational. Similar to Option B.

The domain of the function is [tex]x \in [0,3][/tex]

The range of the function is [tex]f(x) \in [1, 4][/tex]

The intercept of the function is [tex](x,y) = (0, 1)[/tex]

The minimum of the function is [tex]y = 1[/tex]

The maximum of the function is [tex]y = 4[/tex].

Given a closed interval, the minimum and maximum values for the function are contained in its extremes. The domain of the function represents the set of values of [tex]x[/tex] within the interval, where the range is for the set of values of [tex]y[/tex] within the interval. The intercepts of the linear function have the following two forms: (i) [tex](x, 0)[/tex], (ii) [tex](0, y)[/tex]

Domain - The domain of [tex]f(x) = x + 1[/tex] is [tex]x \in [0,3][/tex].

Range - The range of [tex]f(x) = x + 1[/tex] is found below:

Lower bound

[tex]f(0) = 0 + 1[/tex]

[tex]f(0) = 1[/tex]

Upper bound

[tex]f(3) = 3 + 1[/tex]

[tex]f(3) = 4[/tex]

The range of [tex]f(x) = x + 1[/tex] is [tex]f(x) \in [1, 4][/tex].

Intercepts - We proceed to find all intercepts:

x = 0

[tex]f(0) = 1[/tex]

[tex]y = 0[/tex]

[tex]0 = x + 1[/tex]

[tex]x = -1[/tex]

This intercept does not belong to given interval.

(0, 1) is the only intercept of  [tex]f(x) = x + 1[/tex].

Minimum - The minimum value of the interval is [tex]y = 1[/tex].

Maximum - The maximum value of the interval is [tex]y = 4[/tex].

the gcf of 13 and 65 is 13

13 + 65 can be rewritten using the gcf as

13( 1 + 5)

The greatest common factor of 13 and 65 is 13.

The 13 + 65 could be written using the gcf as 13(1 + 5).

Given that,

Answer:

= 3.65.

Step-by-step explanation:

You know that Tom has 23 coins in total. That means the number of dimes and the number of quarters equals 23.

D + Q = 23

You also know that the total value of the coins is $3.65. A dime is worth $0.10 and a quarter is worth $0.25, so:

0.10*D + 0.25*Q = 3.65

That says that 10 cents per dime times the number of dimes, plus 25 cents per quarter times the number of quarters is three dollars and sixty-five cents.

So you have a system of linear equations:

D + Q = 23

0.10D + 0.25Q = 3.65

I'm going to multiply the bottom row by 100 to clear the decimals.

D + Q = 23

10D + 25Q = 365

Now I can multiply the top row by -10 to eliminate the D terms

-10D - 10Q = -230

10D + 25Q = 365

________________

0D + 15Q = 135

15Q = 135

Q = 9

Tom has 9 quarters.

If D + Q = 23, and Q = 9, then:

D + 9 = 23

D = 14

Tom has 14 dimes.

Always good to double check:

9 quarters is worth $2.25. 14 dimes is worth $1.40. These should sum to $3.65.

2.25 + 1.40

Answer: Radius is 3 ft

Step-by-step explanation:

Formular:

[tex]{ \boxed{V = \frac{4}{3} \pi {r}^{3} }} \\ [/tex]

substitute:

[tex]36\pi = \frac{4}{3} \pi {r}^{3} [/tex]

multiply all sides by 3:

[tex](36\pi \times 3) = ( \frac{4}{3} \pi {r}^{3} ) \times 3 \\ \\ 108\pi = 4\pi {r}^{3} [/tex]

divide all sides by π :

[tex] \frac{108\pi}{\pi} = \frac{4\pi {r}^{3} }{\pi} \\ \\ 108 = 4 {r}^{3} [/tex]

divide all sides by 4:

[tex] \frac{108}{4} = \frac{4 {r}^{3} }{4} \\ \\ {r}^{3} = 27[/tex]

take a cube root:

[tex] \sqrt[3]{ {r}^{3} } = \sqrt[3]{27} \\ r = \sqrt[3]{(3 \times 3 \times 3)} \\ r = \sqrt[3]{ {3}^{3} } \\ \\ r = 3[/tex]

Answer:

Range = 5

Mode = 7

Step-by-step explanation:

To find range we first need to find the highest number and the lowest number

3 , 4 , 4 , 7 , 7 ,7 ,7 7, 8

least number = 3

highest number = 8

now substract the lowest number from the highest to get the range

= 8-3

= 5

range = 5

Mode : the most common number in the list will be our mode

7 is our mode as it came 5 time in the list

Answer:

76

Step-by-step explanation:

Firstly I called the original number 'y'

Then i formulated an equation by adding in the processes mentioned in the question: (y + 14) x 2/3 = 60

Then i solved the equation

First I multiplied (y + 14) by 2/3: (y + 14) x 2/3 = (2/3 x y) + (14 x 2/3) = 2y/3 + 28/3

I simplified that to 2y + 28/3 = 60 since you can add fractions which have the same denominator

Then to get rid of the fraction i multiplied both sides by 3 to get 2y + 28 = 180

Then i took away 28 from both sides to get 2y = 152

Then i divided both sides by 2 to get 'y'(the original number) on its on: y = 76

Answer:

x - 44 > 5x - 5 is the simplified version. hope this helps
