Final answer:

To find the answer, first multiply 9 by 8, then add 4, resulting in 76. Finally, subtract 55 to get the answer, which is 21.

Explanation:

To solve the problem, we need to first calculate the sum of 9g and 4 when g=8. This will be 9 × 8 + 4.

After calculating the sum, we will subtract 55 from this amount to get the final answer.

Following the steps:

Therefore, when g = 8, subtracting 55 from the sum of 9g and 4 results in  21.

Answer:

$114.17

Step-by-step explanation:

First we need to convert cubic yard to cubic feet.

One yard is equivalent to three feet, so one cubic yard is 3^3 = 27 cubic feet.

So the cost of one cubic feet is 64/27 = $2.3704

We also need to convert from inches to feet.

One inch is 1/12 feet, so 2 inches is 2/12 = 1/6 feet

Now we need to find the volume of the slab:

Volume = 17 * 17 * (1/6) = 48.1667 ft3

Now, to find the cost, we can use a rule of three:

1 cubic feet -> $2.3704

48.1667 cubic feet -> X

X = 48.1667 * 2.3704 = $114.1743

Final answer:

The new cost of houses after a 25% increase from the original price of £100,000 is £125,000. You calculate this by finding 25% of £100,000, which is £25,000, and then add it to the original price.

Explanation:

The student is asking how to calculate the new cost of houses after a 25% price increase from the previous year when the houses cost
£100,000. To find the new price, we need to calculate 25% of £100,000 and then add that to the original price.

First, find 25% of £100,000:

0.25
(multiplier for 25%)
× £100,000
(original cost)
= £25,000
(the increase).

Next, add the increase to the original cost:

£100,000
+ £25,000
= £125,000.

Therefore, the new cost of the houses after a 25% increase is £125,000.

Let r represent the radius of cylinder.

We have been given that the height of a right circular cylinder is 1.5 times the radius of the base. So the height of the cylinder would be [tex]1.5r[/tex].

We will use lateral surface area of pyramid to solve our given problem.

[tex]LSA=2\pi r h[/tex], where,

LSA = Lateral surface area of pyramid,

r = Radius,

h = height.

Upon substituting our given values in above formula, we will get:

[tex]LSA=2\pi r\cdot (1.5)r[/tex]  

Now we will find the total surface area of cylinder.

[tex]TSA=2\pi r(r+h)[/tex]

[tex]TSA=2\pi r(r+1.5r)[/tex]

[tex]TSA=2\pi r(2.5r)[/tex]

[tex]\frac{TSA}{LSA}=\frac{2\pi r(2.5r)}{2\pi r(1.5r)}[/tex]

[tex]\frac{TSA}{LSA}=\frac{2.5r}{1.5r}[/tex]

[tex]\frac{TSA}{LSA}=\frac{25}{15}[/tex]

[tex]\frac{TSA}{LSA}=\frac{5}{3}[/tex]

Therefore, the ratio of total surface area to lateral surface area is [tex]5:3[/tex].

Answer:

x= [tex]2-\sqrt{3}[/tex]          and          x=[tex]2+\sqrt{3}[/tex]

Step-by-step explanation:

- transfer the -1 to the other side so that the equation reads as [tex]x^{2} -4x+1[/tex]

- factor! think about what numbers add -4 but also multiply to be 1

- you may then realize that there are no numbers with those characteristics

- since that is the case, we have to use the quadratic formula, which is:

               [tex]\frac{-b+\sqrt{b^{2}-4ac }}{y}[/tex]        and         [tex]\frac{-b-\sqrt{b^{2}-4ac }}{y}[/tex]

- the equation is shown as [tex]a^{2}+b^{2}=c^{2}[/tex]

- using the numbers that correspond with those lettered values, plug it in the quadratic formulas

the solutions to the equation [tex]\( x^2 - 4x = -1 \) are \( x = 2 + \sqrt{3} \) and \( x = 2 - \sqrt{3} \)[/tex].

To find the solutions to the equation [tex]\( x^2 - 4x = -1 \)[/tex], we can follow these steps:

1. Move all terms to one side of the equation to set it equal to zero:

 [tex]\[ x^2 - 4x + 1 = 0 \][/tex]

2. We can solve this quadratic equation using the quadratic formula:

  [tex]\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \][/tex]

  where [tex]\( a = 1 \), \( b = -4 \), and \( c = 1 \).[/tex]

3. Plug in the values and simplify:

  [tex]\[ x = \frac{-(-4) \pm \sqrt{(-4)^2 - 4(1)(1)}}{2(1)} \] \[ x = \frac{4 \pm \sqrt{16 - 4}}{2} \] \[ x = \frac{4 \pm \sqrt{12}}{2} \] \[ x = \frac{4 \pm 2\sqrt{3}}{2} \] \[ x = 2 \pm \sqrt{3} \][/tex]

So, the solutions to the equation [tex]\( x^2 - 4x = -1 \) are \( x = 2 + \sqrt{3} \) and \( x = 2 - \sqrt{3} \)[/tex].

Step-by-step explanation:

Answer:

x=2 x=-2

Step-by-step explanation:

f(x)=4x^2−16

f(x)=4(x^2-4)

f(x)=4(x-2)(x+2)

x=2 x=-2

Hope this helps! Please mark brainliest :)

The zeros of the function f(x) = 4x2 − 16 are found by factoring the quadratic equation, which results in two solutions x = -2 and x = 2.

To find the zeros of the function f(x) = 4x2 − 16, we need to set the function equal to zero and solve for x:

0 = 4x2 - 16

To solve this quadratic equation, you can factor out the common factor of 4:

0 = 4(x2 - 4)

We now have a difference of squares, which can be factored further:

0 = 4(x + 2)(x - 2)

Set each factor in the parentheses equal to zero:

So the zeros of the function are x = -2 and x = 2.

Answer:

[tex]y = 66.25(1.11)^x[/tex]

Step-by-step explanation:

Let's plug in 9 for x and 171 for y into the given exponential equation:

y = [tex]ab^x[/tex]

171 = [tex]ab^9[/tex]

Now do the same with (10, 190):

190 = [tex]ab^{10}[/tex]

Write them both in terms of a and set them equal:

a = 171/[tex]b^9[/tex]

a = 190/[tex]b^{10}[/tex]

171/[tex]b^9[/tex] = 190/[tex]b^{10}[/tex]

Multiply both sides by [tex]b^{10}[/tex]:

171b = 190

b = 190/171 = 10/9 ≈ 1.11

Plug this in to find a:

a = 171 / (10/9)^9 ≈ 66.25

So, the exponential model is:

[tex]y = 66.25(1.11)^x[/tex]

Answer:

y = 66.25[(10/9)^x]

Step-by-step explanation:

171 = a(b⁹)

b⁹ = 171/a

190 = a(b¹⁰)

190 = a(171/a) × b

b = 190/171

b = 10/9

(10/9)⁹ = 171/a

a = 66.24890362

We have been given a sphere with radius 8.6 ft. We are asked to find the surface area of the given sphere.

We know that surface area of a sphere is equal to [tex]4\pi r^2[/tex].

[tex]A=4\pi r^2[/tex]

Upon substituting [tex]r=8.6\text{ ft}[/tex] in surface area formula, we will get:

[tex]A=4\pi (8.6\text{ ft})^2[/tex]

[tex]A=4\pi \cdot 73.96\text{ ft}^2[/tex]

[tex]A=295.84\pi\text{ ft}^2[/tex]

[tex]A=929.4087706\text{ ft}^2[/tex]

Upon rounding to nearest hundredth, we will get:

[tex]A\approx 929.41\text{ ft}^2[/tex]

Therefore, the surface of the given sphere would be approximately [tex]929.41\text{ ft}^2[/tex].

In one year, the Perseid meteor shower had a meteor appear every 1 1/5 minutes on average. That same year, the Leonid meteor shower had a meteor appear every 4 2/3 minutes on average. How many more meteors fell during the Perseid meteor shower?

Answer:

325,452 meteors

Step-by-step explanation:

We all know that :

We have 365 days in a year and in each day there are 24 hours, Likewise an hour has 60 minutes

SO, the total number of minutes in a year is :

365 × 24 × 60 = 525600 minutes

For Perseid  meteor:

[tex]1 + \frac{1}{5} \\ \\ = 1 + 0.2 \\ \\ = 1.2[/tex]

So one meteor fall at 1.2 minutes interval Thus, in a year, we will have :

1 meteor - 1.2 minutes.

x meteor - 525600 minutes.

1.2x = 525600

[tex]x = \frac{525600}{1.2}[/tex]

x = 438000

∴  438,000 meteors fell during the Perseid shower.

For  Leonid meteor shower:

[tex]4 + \frac{2}{3} = 4.67[/tex]

So one meteor fall at 4.67 minutes interval Thus, in a year, we will have :

1 meteor - 4.67 minutes.

x meteors - 525600 minutes.

[tex]4.67x = 525600[/tex]

[tex]x = \frac{525600}{4.67}[/tex]

x = 112548

112,548 meteors fell during the Leonid Shower.

Finally , the numbers of more meteors that  fell during the Perseid meteor shower is calculated by the difference in the number of Perseid meteor shower and Lenoid meteor shower. i.e

438,000 - 112,548 = 325,452

325,452 more meteors fell during the Perseid meteor shower

Answer:

For Leonid meteor shower: So one meteor fall at 4.67 minutes interval Thus, in a year, we will have : 1 meteor - 4.67 minutes. x meteors - 525600 minutes

Step-by-step explanation:

We have been an artist is creating a sculpture where a globe with a diameter of 48 inches sits in a cone like a scoop of ice cream. She wants the cone of her sculpture to be geometrically similar to an actual ice cream cone that has a diameter of 2 1/2 inches and a height of 6 inches.

We will use proportions to solve our given problem.

[tex]2\frac{1}{2}=2.5[/tex]

[tex]\frac{\text{Height of sculpture}}{\text{Diameter of sculpture}}=\frac{\text{Height of cone}}{\text{Diameter of cone}}[/tex]

[tex]\frac{\text{Height of sculpture}}{48}=\frac{6}{2.5}[/tex]

[tex]\frac{\text{Height of sculpture}}{48}\cdot 48=\frac{6}{2.5}\cdot 48[/tex]

[tex]\text{Height of sculpture}=6\cdot 19.2[/tex]

[tex]\text{Height of sculpture}=115.2[/tex]

Therefore, the height of the sculpture should be 115.2 inches.
