Answer:

2x+8

Step-by-step explanation:

The mathematical expression will be;

⇒ 2x + 8

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The algebraic expression is,

⇒ '' Eight more than the product of two and a number x''.

Now,

Since, The algebraic expression is,

⇒ '' Eight more than the product of two and a number x''.

Hence, We get the mathematical expression as;

⇒ Product of 2 and number x = 2x

And, 8 more than 2x = 2x + 8

Thus, We get the mathematical expression as;

⇒ 2x + 8

Answer:

[tex]\boxed{5 \cdot \sqrt{2} \cdot \sqrt[6]{5} }[/tex]

Step-by-step explanation:

[tex]\sqrt[3]{250} \cdot \sqrt{\sqrt[3]{10} }[/tex]

[tex]\sqrt{\sqrt[3]{10} } \implies (10^\frac{1}{3} )^\frac{1}{2} =10^\frac{1}{6} =\sqrt[6]{10}[/tex]

[tex]\therefore \sqrt{\sqrt[3]{10} }=\sqrt[6]{10}[/tex]

[tex]\text{Solving }\sqrt[3]{250} \cdot \sqrt{\sqrt[3]{10} }[/tex]

[tex]250=2 \cdot 5^3[/tex]

[tex]\sqrt[3]{250}=\sqrt[3]{2\cdot 5^3}=5 \sqrt[3]{2}[/tex]

Once

[tex]\sqrt[6]{2} \cdot \sqrt[6]{5} = \sqrt[6]{10}[/tex]

We have

[tex]5 \sqrt[3]{2} \cdot \sqrt[6]{2} \cdot \sqrt[6]{5}[/tex]

We can proceed considering the common base of exponentials

[tex]\sqrt[3]{2} \cdot \sqrt[6]{2} = 2^{\frac{1}{3}} \cdot 2^{\frac{1}{6} } = 2^{\frac{3}{6} } = 2^{\frac{1}{2} }=\sqrt{2}[/tex]

Therefore,

[tex]5 \sqrt[3]{2} \cdot \sqrt[6]{2} \cdot \sqrt[6]{5} = 5 \cdot \sqrt{2} \cdot \sqrt[6]{5}[/tex]

Answer:

x = 2

because we have the same question and i got it right its hard to explain but trust me its x = 2

The solution to the given equation is 2. Therefore, option B is the correct answer.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is x/6 = 4/12.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Now, x/6 = 4/12

By cross multiplication, we get

12x=24

⇒ x=2

The solution to the given equation is 2. Therefore, option B is the correct answer.

Answer:

314.16 metres

Step-by-step explanation:

The answer to this problem is essentially just the circumference of the circle.

The circumference, or perimeter, is denoted by C = 2πr = πd, where r is the radius (and half the diameter) and d is the diameter.

Here, the diameter is 100 metres, so plug this in for d:

C = πd

C = π * 100 ≈ 314.16 metres

The answer is about 314.16 metres.

Answer:

0.8208 ; 0.8448

Step-by-step explanation:

Given the following :

Number of tosses = 4

Probability of head on any toss :

P(head) = 0.4

Therefore ;

(1 - p(head)) = (1 - 0.4) = 0.6

Binomial probability :

P(X) = nCx * P^x * (1 - P) ^(n-x)

Where:

n = number of trials ; x = number of success ; P = probability of success.

P(X≤2) = P(0) + P(1) + p(2)

using binomial probability calculator to ensure faster computation:

P(X≤2) = 0.1296 + 0.3456 + 0. 3456

= 0.8208

B)

P(1 ≤ X ≤ 3) = P(1) + P(2) + P(3)

P(1 ≤ X ≤ 3) = 0.3456 + 0.3456 + 0.1536

= 0.8448

Answer:

Step-by-step explanation:

From the given information:

The total number of handshakes can be represented by the combination of 18 combination 2, which can be mathematically expressed as:

[tex]\mathbf{^{18}C_2}[/tex] .

where;

[tex]\mathbf{^{18}C_2}[/tex] is the number of ways two people can shake themselves from a total of 28 people without much regard about the order of arrangement of the handshakes.

[tex]\mathbf{^{18}C_2 = \dfrac{18!}{2!(18-2)!}}[/tex]

[tex]\mathbf{= \dfrac{18!}{2!(16)!}}[/tex]

= 153

From these 6 companies, the possibility that there will be handshakes from within the company is [tex]\mathbf{^3 C_2}[/tex]

[tex]\mathbf{^3 C_2} = \dfrac{3!}{2!(3-2)!}[/tex]

[tex]= \mathbf{ \dfrac{3 \times 2!}{2!(1)!}}[/tex]

= 3

However, number of companies = 6

∴ the number of handshakes within companies = 3 × 6 = 18

But we are being told that :

If the representatives did not shake hands with people from their own company, how many handshakes took place

Therefore, the number of handshakes that took place in regard to the given criteria = 153 - 18

Answer:

There are 20 cups of coffee in two pots of coffee and 36 donuts in 3 boxes of donuts

Step-by-step explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other), the direct rule of three must be applied as follow:

a ⇒ b

c ⇒ x

So [tex]x=\frac{c*b}{a}[/tex]

In this case, the rule of three can be applied as follows:

[tex]amount of cups of coffe=\frac{2coffe pots*10 cups of coffee}{1 coffe pot}[/tex]

amount of cups of coffe= 20

[tex]amount of donuts=\frac{3 boxes*12 donuts}{1 box}[/tex]

amount of donuts= 36

There are 20 cups of coffee in two pots of coffee and 36 donuts in 3 boxes of donuts

Addition and Subtraction of Fractions · 1. Add: (i) 7/ 10 + 2/15 (ii) 2²/₃ + 3¹/₂ · 2. Simplify: (i) 15/16 – 11/12 (ii) 11/15 – 7/20 · 3. Simplify: 4⁵/₆ – 2³/₈ + .

Answer:

7/10 + 2/15= 5/6

2 3/3 + 3 1/2= 6 1/2

15/16 - 11/12= 1/48

11/15 - 7/20= 23/60

Step-by-step explanation:

When adding or subtracting fraction with different denominators, we must find there LCM to be their new denominators. Then divide the new denominator by the old denominator, do for both fractions, then multiply the answer with the numerator, do for both fractions to get their new numerators. Then add or subtract the fractions. Then simplify the answer if needed.

Ex 1:

The LCM of 10 and 15 is 30

7/10 + 2/15

(30 ÷ 10=3, 3 × 7= 21)(30 ÷ 15= 2, 2 × 2=4)

=21/30 + 4/30= 25/30 or 5/6

With whole numbers, add the two whole numbers together. Then n add the fractions. Lastly add both of the answers together.

Ex:

The LCM of 3 and 2 is 6

2 3/3 + 3 1/2

=2 + 3= 5

= 3/3 + 1/2= 9/6 or 1 3/6 or 1 1/2

= 5 + 1 1/2

= 6 1/2

Always remember to simplify if possible or necessary.

Answer:

x = -6

Step-by-step explanation:

36 + x = 12 - 3x

36 + x - 36 = 12 - 3x - 36

x = -3x - 24

x + 3x = -3x - 24 + 3x

4x = -24

4x / 4 = -24 / 4

x = -6

Answer:

x = -6

Step-by-step explanation:

36 + x = 12 - 3x

We need all terms with x on the left side.

Add 3x to both sides.

36 + x + 3x = 12 - 3x + 3x

36 + 4x = 12

We need all terms that are just numbers on the right side. Subtract 36 from both sides.

36 - 36 + 4x = 12 - 36

4x = -24

We have 4x, which means 4 multiplied by x, on the left side. We want x alone. Divide both sides by 4.

x = -6

We know that 2 * 3 = 6 and x * x² = x¹ * x² = x⁽¹⁺²) = x³ so the final answer is 6x³y.

Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

2r + 3s = - 5 → (1)

6s = 2r → (2) ( divide both sides by 2 ), then

r = 3s

Substitute r = 3s into (1)

2(3s) + 3s = - 5

6s + 3s = - 5

9s = - 5 ( divide both sides by 9 )

s = - [tex]\frac{5}{9}[/tex]

Substitute this value into either of the 2 equations and evaluate for r

Substituting into r = 3s, then

r = 3 × - [tex]\frac{5}{9}[/tex] = - [tex]\frac{5}{3}[/tex]

Solution is r = - [tex]\frac{5}{3}[/tex] and s = - [tex]\frac{5}{9}[/tex]

Answer:

a) The perimeter of a rectangle is written as:

P = 2*L + 2*W

where L is the length amd W is the width (broad in this case).

here we have:

L = 8cm and W = b

then the perimeter is:

P = 2*8cm + 2*b

And we know that:

18cm ≤ P ≤ 50cm

where ≤ is used because there is written "not more" and "not less", so the equalities are allowed

now we can replace P by the above equation:

18cm ≤ 16cm + 2*b ≤ 50cm

now we can subtract 16cm in each side and get:

18cm - 16cm ≤ 2*b ≤ 50cm - 16cm

2cm ≤ 2*b ≤ 34cm

Now we can divide each side by 2.

1cm ≤ b ≤ 34cm/2 = 17cm

1cm ≤ b ≤ 17cm.

b) Here we have missing information, so this can not be answered.

(only knowing that one side length is x, and another side length is x + 3cm, we can know that x > 0cm, so the minimum value of x is really close to 0cm)
