Y'all don't make fun of me or anything my brains not working but this is a real question a triangle is 3 sides and a square has 4 right or is the other way around?

Answer: B. 6

Step-by-step explanation:

Let x be the [certain number]

Rephrase the expression

13 less than fourteen times a certain number is twenty-nine more than 7 times that number

14x-13=7x+29

Calculate

Given

14x-13=7x+29

Add 13 on both sides

14x-13+13=7x+29+13

14x=7x+42

Subtract 7x on both sides

14x-7x=7x+42-7x

7x=42

Divide 7 on both sides

7x/7=42/7

x=6

Hope this helps!! :)

Answer:

680,000

Step-by-step explanation:

Population before growing rate: 400,000

Growing rate: 7%

Duration: 10 years

___

First, you will have to calculate how much does the population increase each year with the said rate, so you will have to multiply the rate by the population to determine that amount.

400,000 x 7/100 = 28,000

So the population increases by 28,000 each year, now you will have to multiply that amount by the amount of years to determine how much the amount of increase.

28,000 x 10 = 280,000

This means that the population has increased by 280,000 in these 10 years. Finally, you will have to add that number to the population amount to get the answer.

400,000 + 280,000 = 680,000

Answer:

$142 ; 0.749 ; Normal ; 0.090938

Step-by-step explanation:

Mean and standard deviation :

The mean of the distribution x = $142, because the sample size is sufficiently large, the distribution will be approximately normal (central limit theorem).

Standard deviation of distribution : σ/ sqrt(n)

= 29 / sqrt(1500)

= 0.749

B.)

Shape of sampling distribution of X.

The shape of the sampling distribution will be approximately normal due to the large sample size used. This is according to the central limit theorem whereby distribution of sample converges to normal with increasing sample size. Mean ~ N(142, 0.749²)

C.)

P(X > 143)

Using the relation :

Z = (x - mean) / standard error

Z = 143 - 142) / 0.7489

Z = 1.335

P(Z > 1.335) :

Using the Z probability calculator :

P(Z > 1.335) = 0.090938

Answer:

a) A = 36π in² ≈ 113.09 in²

b)  $0.98 per slice

c) $0.09 per square inch

Step-by-step explanation:

a) area = πr²

    r= diameter/2 = 12/2 = 6

    A = π(6)²

    A = 36π in² ≈ 113.09 in²

b) s = price per slice

   s = 9.75 ÷ 10

   s = $0.975 ≈ $0.98

c) price per square inch = price ÷ area

   = 9.75 ÷ 113.09

   = $0.086 ≈ $0.09 per square inch

Answer:

3:5 = 30:50 because it is ratio 3 x 10 = 30 5 x 10 = 50

Answer:

Number is 4536

Step-by-step explanation:

Assume;

Same number = a

Multiply of 7 = b

So,

a+a+a+b = 39

3a + b = 39

Use b = 7

3a + b = 39

3a + 7 = 39 (Not possible)

Use b = 14

3a + b = 39

3a + 14 = 39 (Not possible)

Use b = 21

3a + b = 39

3a + 21 = 39

a = 6

So,

Number is 6 x 6 x 6 x 21

Number is 4536

Answer:

S is also 13

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

The incenter is the point where all of the angle bisectors meet in the triangle

Using that definition, since point S is the incenter, we know segments RS and SQ are congruent.

1. We can use the Pythagorean Theorem to solve for segment RS first.

a^2+b^2=c^2      or           MR^2+RS^2=MS^2

12^2+b^2=13^2

144+b^2=169

b^2=169-144

b^2=25

b=5                    or                  RS=5

Since segment RS is congruent to segment SQ, SQ=5

Answer:

a^4 - 2a^2b^2 + b^4

Step-by-step explanation:

Here, we want to expand the given expression

Mathematically, we have this as follows;

(a^2-b^2)^2

= (a^2(a^2 - b^2) -b^2(a^2-b^2)

a^4-a^2b^2 - a^2b^2 + b^4

= a^4 - 2a^2b^2 + b^4

Answer:

11

Step-by-step explanation:

) f(x) = 3x2 + 5 and y = 3x2 + 5 ... You read this problem like this: “given f of x equals 4x plus one, find f of 2. ... Given f(x)= 3x – 4, f(5) = 11.

Answer:

x = 1

Step-by-step explanation:

( 6^2 + 1 ) 6^x = ( 36 + 1 ) x " multiply by "  6^x = 222

so 37 x 6^x = 222

divide by 37

6^x = 6^1

so

x = 1

Answer:

we conclude that:

Step-by-step explanation:

Given

u = {1,2,3,4,5,6,7,8,9, 10}

X= {1,2,4,6,7,8,9}

Y= {1,2,3,4,7,9)

Z= {2,3,4,7,9)

To determine

X∩Y∩Z = ?

We know that the intersection of three given sets represents the largest set which consists of all the elements that are common to all the sets.

The intersection of sets is denoted by the symbol '∩'.

Thus,

X= {1,2,4,6,7,8,9}

Y= {1,2,3,4,7,9)

Z= {2,3,4,7,9)

X∩Y∩Z = {2, 4, 7, 9}

Therefore, we conclude that:

Answer: 7.3x + 5

Step-by-step explanation:

For us to solve the question, we have to solve 5.2x+8+2.1x-3 and the answer gotten will allow us know the equivalent expression.

= 5.2x+8+2.1x-3

= 5.2x + 2.1x + 8 - 3

= 7.3x + 5

Therefore, the correct answer is 7.3x + 5

The slope in the first, second, third, and fourth cases will be 2, -3, 5, and 1, respectively. Then the correct options are A, B, F, and H.

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

The slope of the line is given as,

m = (y₂ - y₁) / (x₂ - x₁)

The slope in the first case will be given as,

m = (1 + 1) / (1 - 0)

m = 2

The slope in the second case will be given as,

m = (1 - 4) / (2 - 1)

m = - 3

The slope in the third case will be given as,

m = (28 - 18) / (4 - 2)

m = 5

The slope in the fourth case will be given as,

m = (-3 + 4) / (1 - 0)

m = 1

The slope in the first, second, third, and fourth cases will be 2, -3, 5, and 1, respectively. Then the correct options are A, B, F, and H.
