Given:

Perimeter of the figure = 18.6 inches

To find:

The length of n.

Solution:

Perimeter of the figure = 18.6 inches

Perimeter = Sum of the sides

3 + 6.3 + 4.5 + n = 18.6

13.8 + n = 18.6

Subtract 13.8 from both sides.

13.8 + n - 13.8 = 18.6 - 13.8

n = 18.6 - 13.8

n = 4.8

The length of n is 4.8 inch.

Answer:

None of these solutions

Step-by-step explanation:

Substitute the values for x and y into the equation and see if they work out:

2(1)+3(4)=8

14 is not equal to 8, so (1,4) is not a solution.

2(1)+3(-4)=8

-10 is not equal to 8, so (1, -4) is not a solution.

2(4)+3(1)=8

11 is not equal to 8, so (4,1) is not a solution.

Step-by-step explanation:

Net of a cube is : Basically , a cube consists of six square faces, twelve edges, and eight vertices. When the square faces of a cube are separated at the edges and laid out flat they make a two dimensional figure( 2D figure :- Comprises of x-axis & y-axis) called a net. There are eleven different nets for a cube.

Since we have 11 nets of a cube ! According to question we have only one net given , that means there are 10 more net of a cub are left .Therefore , Correct option is D) 10 .

Answer:

-1.4

Step-by-step explanation:

h(2) = h(2-1) + 1.8

= h(1) + 1.8

= -5 + 1.8

= -3.2

h(3) = h(3-1) + 1.8

= h(2) + 1.8

= -3.2 + 1.8

= -1.4

As per the given expression h(n)=h(n−1)+1.8, then the value of h(3) is -1.4.

In this explanation, we will calculate the value of h(3) using the given recursive formula h(n) = h(n-1) + 1.8 with the initial condition h(1) = -5. We will follow the iterative approach to find the value of h(3) by step-by-step calculations.

We are given the recursive formula h(n) = h(n-1) + 1.8, where h(1) = -5. Let's find the value of h(3) using this formula.

Step 1: Calculate h(2)

To find h(2), we use the recursive formula:

h(2) = h(1) + 1.8

h(2) = -5 + 1.8

h(2) = -3.2

Step 2: Calculate h(3)

Now, to find h(3), we again use the recursive formula:

h(3) = h(2) + 1.8

h(3) = -3.2 + 1.8

h(3) = -1.4

The best estimate for what their down payment will be $5850

A conventional loan is any mortgage loan that is not insured or guaranteed by the government.

Given that, The Franzes are purchasing a home for $195,000, and they are using a conventional loan.

We know, the minimum down payment required for a conventional mortgage is 3%

Answer:

55440 different arrangements

Step-by-step explanation:

The answer is:

11 x 10 x 9 x 8 x 7

Which is equal to 55440 different arrangements

Support me by marking my answer as brainiest

Mac can create 55,440 different arrangements by using 5 out of his 11 pictures, calculated using the permutation formula P(11, 5).

The question asks how many different arrangements Mac can make using 5 out of 11 different pictures. To calculate this, we use the concept of permutations which is given by the formula P(n, r) = n! / (n-r)!, where n is the total number of items, and r is the number of items to arrange.

In this case, Mac has 11 pictures (n = 11) and wants to arrange 5 of them (r = 5). Thus, the number of arrangements (permutations) can be found by the calculation: P(11, 5) = 11! / (11-5)! = 11! / 6!, which equals 11 x 10 x 9 x 8 x 7 = 55,440 different arrangements.

Answer:

x =0

Step-by-step explanation:

3=x+3–5x

Combine like terms

3 = 3-4x

Subtract 3 from each side

3-3 = 3-3-4x

0 =-4x

Divide each side by -4

0/-4 = -4x/-4

0 =x

Answer:

x=0

Step-by-step explanation:

3=x+3-5x add like terms

3= -4x+3

3=-4x+3 subtract 3 from both sides

0=-4x divide on both sides -4/-4 and 0/-4

To find out how many cherries Rachel picked, the mixed numbers are converted to improper fractions, multiplied, and the result is converted back to a mixed number. Rachel picked 3 11/15 pounds of cherries.

The question asks how many cherries Rachel picked, given that Melissa picked 1 3/5 pounds of cherries and Rachel picked 2 1/3 times more than Melissa. To find this out, we need to convert the mixed numbers into improper fractions, multiply and then convert back to a mixed number if necessary.

First, convert Melissa's cherries to an improper fraction: 1 3/5 = 8/5. Next, convert the number of times more Rachel picked: 2 1/3 times more = 7/3. Now, calculate Rachel's cherries: (8/5) * (7/3) = 56/15. Finally, convert 56/15 to a mixed number: 56/15 is 3 11/15. So, Rachel picked 3 11/15 pounds of cherries.

Answer:

the number of caffeine still in his system by 9:00 am is 192 mg.

Step-by-step explanation:

given information

the mass of initial caffein, m₁ = 300 mg

time, t = 9 - 6 = 2 hours

metabolised = 18%/hour = 0.18/h = 0.18 x 300 mg = 54 mg/h

the student metabolised the caffeine 54 mg/h. thus from 6 am to 9 am the caffeine metabolised is

metabolised in 2 hr = 2 x 54

                                 = 108 mg

the remaining caffeine = initial caffeine - metabolised caffeine

                                      = 300 - 108

                                      = 192 mg

Answer:

The correct answer is 138 mg.

Step-by-step explanation:

To understand this problem we must first analyze it.

We know that the student's body metabolizes 18% of the caffeine ingested every hour.

Therefore we can solve that percentage to already have the number of metabolized caffeine per hour:

(300. 18): 100 =

5400: 100 = 54 mg

We now know that the student's body will metabolize 54 mg of caffeine per hour.

The question is much caffeine is still in his system by 9:00 am?

From 6:00 am to 9:00 am we have 3 hours of difference: 3 . 54 = 162

In three hours 162 mg of caffeine were already processed by his body, therefore, it still needs to be metabolized: 300 - 162 = 138 mg.

The expression which is false in determining the volume of the cylinder is given by V₁ = π . 3 . 12²

A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder. The volume of a cylinder is

Volume of Cylinder = πr²h

Surface area of cylinder = 2πr ( r + h )

where r is the radius of the cylinder

h is the height of the cylinder

Given data ,

Let the volume of the 12 cylinders be V

Let the height of the cylinder be h = 1 cm

Let the radius of the cylinder be r = 3 cm

Now , Volume of Cylinder = πr²h

On simplifying , we get

Volume of the cylinder V = 12 x ( π x 3² x 1 )

Volume of the cylinder V = π x 3² x 12 cm³

Volume of the cylinder V = 108π cm³

So , the expression V₁ = π . 3 . 12² is false and cannot be used to determine the volume of the cylinder

Hence , the volume of cylinder is 108π cm³
