Help me answer this question

Answer:

x = 18

Step-by-step explanation:

Since 30-60-90 triangles have a side ratio of y : y√3 : 2y.

Since 2y, here, is 12√3, then y is 6√3.

This means that the side x, is 6√3 * √3, which is:

x = 6√3 * √3

= 6 * 3

x = 18

Answer:

Yes

Step-by-step explanation:

Yes, 600,000,25 is greater than 62,500.

Answer:

0

Step-by-step explanation:

If ∑aₙ converges, then lim(n→∞)aₙ = 0.

Using ratio test, we can determine if the series converges:

If lim(n→∞) |aₙ₊₁ / aₙ| < 1, then ∑aₙ converges.

If lim(n→∞) |aₙ₊₁ / aₙ| > 1, then ∑aₙ diverges.

lim(n→∞) |(100ⁿ⁺¹ / (n+1)!) / (100ⁿ / n!)|

lim(n→∞) |(100ⁿ⁺¹ / (n+1)!) × (n! / 100ⁿ)|

lim(n→∞) |(100 / (n+1)|

0 < 1

The series converges.  Therefore, lim(n→∞)aₙ = 0.

Step-by-step explanation:

6a - 4b + c + 4a + 4b + c

Solving like terms

Because - 4b + 4b = 0

Answer:

There are 5 different outcomes, $30, $21, $20, $16 and $11.

Step-by-step explanation:

Bonnie has a total of 6 bills in her pocket. If she takes 3 random bills, this means that there are 20 different possibilities but the five dollar bills and ten dollar bills are not indistinctive so the number is not 20 for this example.

She can take the 1 dollar bill and the two 5 dollar bills which would make 11 dollars.

She can take the 1 dollar bill and the two 10 dollar bills which would make 21 dollars.

She can take the 1 dollar bill, one 5 dollar bill and one 10 dollar bills which would make 16 dollars.

She can take two 5 dollar bills and one 10 dollar bill which would make 20 dollars.

She can take two 10 dollar bills and one 5 dollar bill which would make 30 dollars.

So there are 5 different outcomes, $30, $21, $20, $16 and $11.

I hope this answer helps.

Final answer:

Bonnie could have possibly drawn $11, $21, $20, or $25 by selecting any 3 bills out of 1 one-dollar bill, 2 five-dollar bills, and 2 ten-dollar bills.

Explanation:

The question concerns the amount of money Bonnie could have taken from her pocket after randomly selecting 3 bills. To answer this, let's consider her initial set of bills: 1 one-dollar bill, 2 five-dollar bills, and 2 ten-dollar bills.

Here are the possible combinations of 3 bills she could draw:

1 one-dollar bill and 2 five-dollar bills: $1 + $5 + $5 = $11

1 one-dollar bill and 2 ten-dollar bills: $1 + $10 + $10 = $21

2 five-dollar bills and 1 ten-dollar bill: $5 + $5 + $10 = $20

1 five-dollar bill and 2 ten-dollar bills: $5 + $10 + $10 = $25

Therefore, the amounts of money Bonnie could have drawn are $11, $21, $20, and $25.

Answer:

The mean for the whole group is 12.57 cm

Step-by-step explanation:

The mean of the length of each group's finger is given by the following formula:

mean = (sum of lengths from each finger)/number of people

Therefore for the first group:

8.3 = (sum1)/6

sum1 = 8.3*6 = 49.8

For the second group:

17.7 = sum2/5

sum2 = 17.7*5 = 88.5

Therefore the mean from the whole group is:

mean = (sum1 + sum2)/11 = (49.8 + 88.5)/11 = 12.57 cm

Answer:

10x-2y

Answer:

The value of y is 16.

Step-by-step explanation:

You have to substitute x = 2 into the equation :

[tex]y = {3x}^{2} + 4[/tex]

Let x = 2,

[tex]y = 3( {2)}^{2} + 4[/tex]

[tex]y = 3(4) + 4[/tex]

[tex]y = 12 + 4[/tex]

[tex]y = 16[/tex]

Answer:

y = 16

Step-by-step explanation:

Let's solve your equation together

3x^2 + 4

We have been given that x = 2

So first we must replace x by 2.

y = 3(2)^2 + 4

Now we solve the equation

2^2 = 4

y = 3(4) + 4

3 * 4 = 12

y = 12 + 4

12 + 4 = 16

y = 16

Answer:

$22500

Step-by-step explanation:

First, we have to find the total budget for this year.

They spend 10% on entertainment and $2450 will be spent on entertainment this year.

Let the total budget this year be x. Therefore:

[tex]\frac{10}{100} * x = 2450[/tex]

Simplifying:

[tex]10x = 2450 * 100 \\\\10x = 245000\\\\x = 245000 / 10[/tex]

=> x = $24500

Their total budget of this year is $24500.

Since they will spend $2000 more this year than last year, we have to deduct $2000 from this year's budget to find last year's.

This means that their budget last year was:

$24500 - $2000 = $22500

Their budget last year was $22500.

Answer:9.75304923404

Step-by-step explanation:

the system of equations corresponding to the augmented matrix is:

-8x - 2y - 1z = -15 ,0x - 9y - 6z = -11 ,-2x + 1y - 21z = -1

what is augmented matrix ?

An augmented matrix is a way of representing a system of linear equations in a matrix form. It consists of a rectangular array of numbers, where the coefficients of the variables in each equation are placed in one part of the matrix

In the given question,

To write the system of equations corresponding to the augmented matrix, we need to represent the coefficients and constants of the variables.

The given augmented matrix corresponds to the following system of linear equations:

-8x - 2y - 1z = -15

0x - 9y - 6z = -11

-2x + 1y - 21z = -1

where x, y, and z are variables.

Therefore, the system of equations corresponding to the augmented matrix is:

-8x - 2y - 1z = -15

0x - 9y - 6z = -11

-2x + 1y - 21z = -1

Answer:

x = -1 and x = 9

Step-by-step explanation:

3(x-4)^2 = 75

(x-4)^2 = 75/3 = 25

(x-4)=[tex]\sqrt25[/tex]

(x-4)= 5   or (x-4)=-5

x=9 or x= -1

Final answer:

To solve the quadratic equation 3(x - 4)^2 = 75, we isolate the squared term, take the square root of both sides, and solve for x, which gives us the solutions x = -1 and x = 9.

Explanation:

The equation given is 3(x - 4)2 = 75. To solve for x, follow these steps:

So, the solutions to the equation are x = -1 and x = 9.
