Answer:

110 walnuts

Step-by-step explanation:

There are 330 walnuts in 6 bags.

Each bag has the same number of walnuts

Hence, the number did walnuts in one bag=

6 bags = 330 walnuts

1 bag = x walnuts

Cross Multiply

6 × x = 1 × 330 walnuts

x = 330 walnuts/6

x = 55 walnuts

Each bag contains 55 walnuts

The number of walnuts that are in 2 bags is calculated as:

1 bag = 55 walnuts

2 bags =

2 × 55 walnuts

= 110 walnuts

There are 110 walnuts in 2 bags.

[tex]a : 4^2\\\\b: 4ft[/tex]

Step-by-step explanation:

[tex]\sqrt{16} = 4\\a : 4^2\\\\b: 4ft[/tex]

The area of the solar panel written as a power is 4 square feet.

The side lengths of the solar panel are 4 feet.

Area of square is the square of its side.

It is given that a square solar panel has an area of 16 square feet.

By simply using this formula;

[tex]\sqrt{x} = x^\frac{1}{2}[/tex]

Taking root square we get;

[tex]\sqrt{16} = 4[/tex]

Thus, power = [tex]4^{2} ft[/tex]

Answer:

            y  =  [tex]\frac{1}{2}[/tex] x - 5

Step-by-step explanation:

 Given expression:

        2x + y  = -5

Find the equation of the line perpendicular

Solution:

A line perpendicular to this line will have a negative inverse slope;

  Equation of any line is given as;

           y  = mx + c

y and x are the coordinates

 m is the slope

  c is the intercept

 Re-write;

         2x + y  = -5

                y  = -2x - 5

Now,

          we know that the slope is -2

A line perpendicular will have a slope of [tex]\frac{1}{2}[/tex] ;

  So;

   Equation of the line is;

            y  =  [tex]\frac{1}{2}[/tex] x - 5

Answer:

a=2.42, b=2.16

16.94>10

Step-by-step explanation:

We are given: 2a+b =7 and 3a-2b=3 , We need to find how much is 7a greater than 10.

First we need to solve equations to find value of a

[tex]2a+b =7---eq(1)\\ 3a-2b=3---eq(2)[/tex]

Multiply eq(1) by 2 and add both equations

[tex]4a+2b =14\\ 3a-2b=3\\------\\7a=17\\a=\frac{17}{7}\\a=2.42[/tex]

Putting value of a in eq(1) to find b

[tex]2a+b=7\\2(2.42)+b=7\\4.84+b=7\\b=7-4.84\\b=2.16[/tex]

Now, a = 2.42 and b=2.16

Finding by how much is 7a  greater than 10

[tex]7a>10[/tex]

Putting a = 2.42

[tex]7a>10\\7(2.42)>10\\16.94>10[/tex]

Answer:

B

Step-by-step explanation:

24 - 7 = 17.

If there are 365 days in a year, sometimes 366, you would multiply 17 by 365 or 366.

17 x 365 = 6205

17 x 366 = 6222.

if 3/4 years aren't leap year, then there answer would be B, 365.

Please mark brainliest! I had to make a new account. Hope this helps! <3

Answer and Step-by-step explanation:

The computation is shown below;

As we know that

The simple interest is

Simple interest = Principal × rate × time

For Account A, the principal would be

2 = Principal × 3.2% × 3

So, the principal is $20.83

For account B, the principal would be

38.50 = Principal × 2.2% × 30

So, the principal is $58.33

Now the interest for both the accounts are as follows

For account 1

= $20.83 × 3.2%

= $0.67

And, for the account 2

= $58.33 × 2.2%

= $1.28

As it can be seen that the account 2 has the highest interest

I hope that helped you!! sorry if not!!

Answer: a = -8

3(2x - a) = 2(3x + 12)

⇔ 6x - 3a = 6x + 24

⇔ - 3a = 24

⇔ a = -8

Step-by-step explanation:

Answer:

X=24

Step-by-step explanation:

3(2x-a)=2(3x+12)

6x-3a=6x+24

-6x both sides.

-3a=x+24

Get rid of the -3a.

x+24

divide by x both sides.

x=24

Answer:

[tex]g(x) = -0.1x^2 + 0.5x + 3.6[/tex]

Step-by-step explanation:

Given

[tex]h(x) = -0.1x^2 + 0.7x + 3[/tex]

Required

Determine the new function

From the question, we understand that the new function wants the water to hit the ground 1 ft farther.

1 ft farther implies x + 1

So, in the given function, we substitute x + 1 for x in [tex]h(x) = -0.1x^2 + 0.7x + 3[/tex]

This gives:

[tex]h(x + 1) = -0.1(x + 1)^2 + 0.7(x + 1) + 3[/tex]

Expand Bracket

[tex]h(x + 1) = -0.1(x + 1)(x + 1) + 0.7(x + 1) + 3[/tex]

[tex]h(x + 1) = -0.1(x^2+2x+1) + 0.7(x + 1) + 3[/tex]

[tex]h(x + 1) = -0.1x^2-0.2x-0.1 + 0.7x + 0.7 + 3[/tex]

Collect Like Terms

[tex]h(x + 1) = -0.1x^2-0.2x + 0.7x + 0.7 + 3-0.1[/tex]

[tex]h(x + 1) = -0.1x^2 + 0.5x + 3.6[/tex]

Hence, the new function is:

[tex]g(x) = h(x + 1) = -0.1x^2 + 0.5x + 3.6[/tex]

[tex]g(x) = -0.1x^2 + 0.5x + 3.6[/tex]

The new model for path of water will be, [tex]h(x+1)=-0.1x^{2} +0.5x+3.6[/tex]

To understand more, check below explanation.

The height h (in feet) of water spraying from the garden house can be modeled by,

                 [tex]h(x)=-0.1x^{2} +0.7x+3[/tex]

where x is the horizontal distance (in feet) from where you are standing.

Since, you raise the hose so that the water hits the ground 1 foot farther from where you are standing.

So that, new function will be,

              [tex]h(x+1)=-0.1(x+1)^{2} +0.7(x+1)+3\\\\h(x+1)=-0.1(x^{2} +2x+1)+0.7x+0.7+3\\\\h(x+1)=-0.1x^{2} -0.2x-0.1+0.7x+0.7+3\\\\h(x+1)=-0.1x^{2} +0.5x+3.6[/tex]
