She will need 9 tins to cover all the panels.

To find how many tins will she need to cover the 30 panels for her allotment and her garden, we need to calculate the total area of the panels and then, calculate how many tins will she need knowing that each liter of tin, covers 12 square meters.

We are given the dimensions of the panels:

[tex]Long=1.8m\\Hight=2m[/tex]

Now, calculating the area of one (1) panel, we have:

[tex]Area=long*height=1.8m*2m=3.6m^{2}[/tex]

So , the total area of all 30 panels is:

[tex]TotalArea=30*3.6m^{2}=108m^{2}[/tex]

Then, calculating how many tins will she need to paint all the panels, we have:

[tex]NeededTins=\frac{TotalArea}{AreaToCoverWithOneTin}\\\\NeededTins=\frac{108m^{2}}{12m^{2} }=9[/tex]

Hence, we have that she will need 9 tins to cover all the panels.

To treat 30 panels, Nancy will need 9 tins of wood preservative.

The total area of 30 panels:

Each panel is 1.8m * 2m = 3.6m²

Total area for 30 panels = 30 panels * 3.6m²/panel = 108m²

Calculate the number of tins needed:

1 litre of preservative covers 12m²

Number of tins needed = Total area / Area covered by 1 tin = 108m² / 12m² = 9 tins

Answer:

A) 5 + 2 =7 x 4= 28

B) 8

Step-by-step explanation:

A) 5 x 4 = 20 and 2 x 4 = 8 so you add 20 + 8 and you get 28

B)  so 5 x 4 is 20 and there is 8 left over and if you do 2 x 4 you get 8

To determine the number of egg salad sandwiches served, we set up an equation 5x + 2x = 28, where x is the number of egg salad sandwiches, and solve for x to find that 4 sandwiches were egg salad sandwiches.

To solve for the number of egg salad sandwiches served at the restaurant, we set up the following equation based on the proportion given: let x be the number of egg salad sandwiches, and 5 times x will be the number of tuna sandwiches since there are 5 tuna sandwiches for every 2 egg salad sandwiches.

The total number of sandwiches is 28, which gives us the following equation:

5x + 2x = 28

We then combine like terms:

7x = 28

Next, we divide both sides of the equation by 7 to solve for x:

x = 28 / 7

x = 4

This means that 4 sandwiches were egg salad sandwiches.

The last digit of 73 factorial (73!) is 0 because any factorial of a number greater than 4 ends in 0 due to the multiplication with 2 and 5.

The last digit in a factor of an integer is dependent upon the pattern of the last digits in its individual factors. We know that factorial of any number greater than 4 ends in 0 because factorial operation involves multiplication by 2 and 5. Since 2 and 5 are factors of any number greater than 4, and the multiplying them results in 10, the final digit will always be 0.

In our case, the student wants to find out the last digit in 73!, which is far greater than 4. So, the last digit of 73! is 0.

Answer:

right triangle

Step-by-step explanation:

We know that the total angles of the triangle are 180 degrees:

(x) + (4x-10) + (2x+15) = 180

7x - 10 + 15 =180

7x + 5 = 180

7x = 180 - 5

7x = 175

x = 175÷ 5 = 25

Now we calculate each angle

x=25

4x-10= (4*25) -10=100-10=90

2x+15=(2*25)+15=50+15=65

Because we have a right angle, then the triangle is right triangle

Final answer:

The volume of Kathy's stacks is 24 cm³ greater than Marco's stacks. Each cube has a volume of 8 cm³, and after multiplying by the number of cubes each person has and subtracting, we find the difference in volume.

Explanation:

To calculate how much greater the volume of Kathy's stack of cubes is compared to Marco's, we need to determine the volume of both sets of cubes and then subtract the smaller volume from the larger one. Each cube has a volume of 2 cm × 2 cm × 2 cm, which equals 8 cm³.

Kathy has 8 cubes, so her total volume is:

8 cubes × 8 cm³ per cube = 64 cm³.

Marco has 5 cubes, so his total volume is:

5 cubes × 8 cm³ per cube = 40 cm³.

To find out how much greater Kathy's volume is:

Kathy's volume – Marco's volume = 64 cm³ – 40 cm³ = 24 cm³.

Therefore, the volume of Kathy's stacks is 24 cm³ greater than Marco's stacks.

The volume formula of a sphere is V = 4/3 π r^3.

Radius of this problem = 7.5.

So, V = 4/3 π (7.5) ^3.

Answer: -125p12z18u3

Reason:

Square negative five twice, so: -5 x -5 x -5 = -125

The first squaring is -5 x -5, which is 25. The second squaring is 25 x (-5), which is - 125.

When it comes to the letters, they act like they are being multiplied.

(p4)3 = p12

(z6)3 = z18

(u)3 = u3

So the answer is -125p12z18u3.

Answer:

(f * g)(2) =  -11√2 +66

Step-by-step explanation:

Points to remember

Let f(x) and g(x) be the two functions, then (f * g) can be written as,

(f * g) = [f(x)][g(x)]

To find the value of (f * g)(2)

we have,

f(x) = -5x - 1 and g(x) =√x - 6

f(2) = -5*2 - 1 = -11

g(2) = √x - 6 = √2 - 6

(f * g)(2) = [f(2)][g(2)]

 = -11 (√2 - 6)

= -11√2 +66

Therefore (f * g)(2) =  -11√2 +66

Answer:

45 years

Step-by-step explanation:

First, lets break the problem down, step-by-step.

Jeremy's age can be represented using the varibale, j.

His father's age is 53, or 11 less than j squared.

Jeremy's father's age can be represented using the following equation:

j^2 - 11 = 53

Now, solve for j.

j^2 - 11 = 53

j^2 = 64

j = 8

That means Jeremy is 8 years old. Now, find the difference between his age and his father's age.

53 - 8 = 45.

So, Jeremy's father is 45 years older than his son.

I hope this helps! :)

To find how many years older Jeremy’s father is than Jeremy, we determined that Jeremy is 8 years old and his father is 45 years older than him. We did this by solving the equation derived from the problem statement. Thus, Jeremy's father is 45 years older than Jeremy.

To solve the problem, let's denote Jeremy's age by x. According to the problem, Jeremy’s father’s age is 11 less than Jeremy’s age squared. The given information states that Jeremy’s father is 53 years old.

We can write this as an equation:

[tex]x^2 - 11 = 53[/tex]

[tex]x^2 = 53 + 11[/tex]

[tex]x^2 = 64[/tex]

Taking the square root of both sides, we get:

x = 8

So, Jeremy is 8 years old. Now, to determine how many years older Jeremy’s father is than Jeremy:

53 (father's age) - 8 (Jeremy's age) = 45

Thus, Jeremy’s father is 45 years older than Jeremy.

Given function,

[tex]f(x)=(x^4-16)(x^2+3x-18)[/tex]

[tex]=((x^2)^2-(4)^2)(x^2+(6-3)x-18)[/tex]

[tex]=(x^2-4)(x^2+4)(x^2+6x-3x-18)[/tex]

[tex]=(x-2)(x+2)(x^2-(2i)^2)(x(x+6)-3(x+6))[/tex]

[tex]=(x-2)(x+2)(x+2i)(x-2i)(x-3)(x+6)[/tex]

For zeros of function f(x),

f(x) = 0

[tex]\implies (x-2)(x+2)(x+2i)(x-2i)(x-3)(x+6)=0[/tex]

By zero product property,

We get,

x = 2, -2, -2i, 2i, 3, -6

Hence, the real roots of f(x) are 2, -2, 3, -6.

Also, the roots lie at the point where a function intersects the x-axis.

Hence, the positions of the roots of f(x) in the graph are ,

(2, 0), (-2, 0), (3, 0) and (-6, 0)

(180-30)/2 would be the equation and the answer is 150/2

The value of x (the perpendicular side) in the given right triangle is approximately 21.2137.

In a right triangle with a 45° angle, we can use the trigonometric function sine (sin) to find the value of the perpendicular side (x) when the hypotenuse is given.

sin(angle) = opposite / hypotenuse

Here the angle is 45°, and the hypotenuse is 30.

Therefore, we can write the equation as:

sin(45°) = x / 30

To solve for x, we can rearrange the equation:

x = sin(45°) × 30

Using the value of sin(45°) = 0.7071 (approximately), we can calculate x:

x = 0.7071 × 30

x = 21.2137

Therefore, the value of x (the perpendicular side) in the given right triangle is approximately 21.2137.
