Answer:

19

Step-by-step explanation:

Simplify the following:

35/5 + 3 (30 - 3^3 + 1)

The gcd of 35 and 5 is 5, so 35/5 = (5×7)/(5×1) = 5/5×7 = 7:

7 + 3 (30 - 3^3 + 1)

3^3 = 3×3^2:

7 + 3 (30 - 3×3^2 + 1)

3^2 = 9:

7 + 3 (30 - 3×9 + 1)

3×9 = 27:

7 + 3 (30 - 27 + 1)

30 + 1 = 31:

7 + 3 31 - 27

| 2 | 11

| 3 | 1

- | 2 | 7

| 0 | 4:

7 + 3×4

3×4 = 12:

7 + 12

7 + 12 = 19:

t=10

Step-by-step explanation:

t+14=24

 -14   -14

t=10

Answer:

t = 10

Step-by-step explanation:

t + 14 =24

Subtract 14 from both sides:

t = 10

Check your work by substitution:

10 + 14 = 24

24=24

t = 10

Let's see what to do buddy...

_________________________________

To do this, we have to multiply the face and denominator of the fraction by the denominator conjunction, which is :

[tex](5 -\sqrt{2}) [/tex]

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

Reminder :

[tex](a + b)(a - b) = {a}^{2} - {b}^{2} \\ [/tex]

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

So we have :

[tex] \frac{1}{ 5-\sqrt{2} } \times \frac{ 5+\sqrt{2} }{ 5 +\sqrt{2} } = \frac{1 \times ( 5 +\sqrt{2}) }{(5- \sqrt{2} )( 5 +\sqrt{2}) } = \\ [/tex]

Answer:

⇛(5+√2)/23.

Step-by-step explanation:

Given,

1/(5-√2)

The denominator is 5-√2.

We know that

The rationalising factor of a+√b is a-√b.

Therefore, the rationalising factor of 5-√2 is 5+√2. To rationalise the denominator is 1/(5-√2), we multiply this by (5+√2)/(5+√2).

∴ 1/(5-√2)

= {1/(5-√2)}×{(5+√2)/(5+√2)}

= {1(5+√2)}/{(5)²-(√2)²} [∵(a-b)(a+b)=a²-b²]

= {1(5+√2)}/{(5*5)-(√2*2)}

= {1(5+√2)}/25 - 2

= {1(5+√2)}/23

= (5+√2)/23

Hence the denominator is rationalised.

Step 3

Step-by-step explanation:

Answer:

1. The independent variable is a and the dependent variable is m

2. The domain is discrete

Step-by-step explanation:

let us explain the difference between discrete or continuous domains

Discrete domain: It is a set of input values that consists of only certain numbers in an interval.

Continuous domain: It is a set of input values that consists of all numbers in an interval.

In the question

m = 3a, where

m is the amount of money m in dollars

Each customer can buy a maximum of three apps

1.

∵ m is depended on the value of 3a

∴ m is the dependent variable ⇒ (output)

∴ a is the independent variable ⇒ (input)

∴ The independent variable is a and the dependent variable is m

2.

∵ The domain the input values

∴ Each customer can buy a maximum of three apps

→ That means it is a certain numbers

∴ The domain is discrete

Answer:

61

Step-by-step explanation:

366/6

36/6 = 6

6/6 = 1

So, 366/6 = 61

The Quotient is 21.

One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things.

Given:

366 divided by 6

So, the Division is

                             6 | 3 6 6 | 21

                                   3 6

                              -  ____

                                     0  6

Step-by-step explanation:

Area of a triangle is given by

[tex]A = \frac{1}{2} \times base \times height \\ [/tex]

From the question

base = 18

height = 6

So we have

[tex]A = \frac{1}{2} \times 18 \times 6 \\ = 9 \times 6 \\ = 54 \: \: \: \: \: [/tex]

We have the final answer as

Hope this helps you

Answer:

The answer is 54 units squared

Step-by-step explanation:

This is because this triangle is made up of two triangles. The smaller one is an isosceles triangle, meaning all sides are the same length. Sense all sides are the same length each side = 6 units squared. You subtract 6 from 18 to get the length of the other triangles side.

From there you multiply each side as if it were a square, then divide both answers by two (because two triangles make up a square). Add them up and then Ta-daa! 54!

Answer:

Step-by-step explanation:

The age of three sisters are consecutive integers meaning they are only one year apart.

E.g. sister 1 = x yrs old

Sister 2 = (x + 1) yrs old

Sister 3 = (x + 2) yrs old

They have a sum of 180 meaning if you add all 3 of their ages, you get a total of 180.

Sister 1 + sister 2 + sister 3 = 180

x + (x + 1) + (x + 2) = 180

So gather the like terms and you get:

3x + 3 = 180

Subtract 3 from both sides

3x = 180-3 = 177

Solve for x by dividing both sides by 3.

x = 177/3 = 59

So now we know what x is so you just plug it back into the equations at the beginning for the ages of each of the sisters.

Sister 1 = x = 59

Sister 2 = x + 1 = 59 + 1 = 60

Sister 3 = x + 2 = 59 + 2 = 61

I think its b because is says loosing 1/4 lbs each week. That would be subtraction. The others are adding.

The equation that represents two Gorillas weighing the same is,

B. 135 + (1/2)x = 143 - (1/4)x.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, A mountain gorilla weighs 135 pounds and is gaining 1/2 pound each week and an eastern gorilla weighs 145 pounds and is losing 1/4 pound each week.

The weights of the two Gorillas will be the same when we'll equate their individual equations which is,

135 + (1/2)x = 143 - (1/4)x.

Solving for 'x' would give us the number of weeks required for two Gorillas

to weigh the same.

Honda made 32 cars

Step-by-step explanation:

Total no. of cars = 60

car made by ford = 3/10 of total no of cars

car made by ford = 3/10 of 60 = 3/10* 60 = 18

car made by General Motors = 1/6of total no of cars

car made by General Motors = 1/6 of 60 = 1/6* 60 = 10

No of cars made by Honda = Total no. of cars - car made by ford - car made by General Motors

No of cars made by Honda = 60 - 18 - 10 = 32

In this lot, Honda made 32 cars.

We check the triangle's inequalities if we add the third side of 20 cm:

Since one of the inequalities is not verified, the three given side lengths cannot form a triangle.

(Because the sum of two sides is equal to the third, we can say the triangle is degenerated to a segment.)

We check the triangle's inequalities if we add the third side of 15 cm:

Answer:

The correct options are;

1) The mean (average) score for each class is the SAME

2) The variance of Class B is 159.14

3) Class B has a greater spread

4) Based on the data A score of 8 is more likely in class B than in class A

Step-by-step explanation:

The given data are;

For the 1st period (Class A), we have

The mean, μ = (10 + 15 + 20 + 25 + 30 + 35 + 40)/7 = 175/7 = 25

The standard deviation σ, is given as follows;

[tex]\sigma =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{N}}[/tex]

Where;

N = The number population size = 7

[tex]x_i[/tex] = The individual data values

Solving using Microsoft Excel formula STDEV.P gives, σ = 10

[tex]\sigma _A[/tex] ≈ 10

The variance = σ² = 10² = 100

For the 2nd period (Class B), we have

The mean, μ = (7 + 12 + 17 + 25 + 33 + 38 + 43)/7 = 175/7 = 25

The standard deviation σ, is given as follows;

[tex]\sigma =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{N}}[/tex]

Where;

N = The number population size = 7

[tex]x_i[/tex] = The individual data values

Solving using Microsoft Excel formula STDEV.P gives, [tex]\sigma _B[/tex] ≈ 12.615

[tex]\sigma _B[/tex] ≈ 12.615 > [tex]\sigma _A[/tex] ≈ 10, class B has greater spread

The variance = σ² = 12.615² ≈ 159.14

A score of 8 is more likely in class B than in class A due to the availability of data before and after the a score of 8

Step-by-step explanation:
