find the valu of x.​

Answer:

13 boxes

Step-by-step explanation:

To calculate the minimum number of boxes that can be had with that amount of paper, they should be kept in the largest box, that is, the 27 cubic foot box, therefore, we divide:

257/27 = 9.51

Which means that we can save the paper in 9 boxes of 27 cubic feet, now we will save the rest in the next smaller box, the 9 cubic foot box.

First let's calculate how many leftover paper:

257 - 27 * 9 = 14

Therefore, we can only use 1 box of 9 cubic feet:

14 - 9 = 5

For the remaining 5 cubic feet use 1 box of 3 cubic feet and 2 boxes of 1 cubic foot.

Therefore, in total it would be:

9 of 27 ft ^ 3 + 1 of 9 ft ^ 3 + 1 of 3 ft ^ 3 + 2 of 1 ft ^ 3 = 13

a total of 13 boxes would be the minimum

Answer:

the total value of the liquid in the container is $29.4

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a cone

The volume of a cone is expressed as

V=1/3(πr²h)

Given data

Height h= 9 inches

Radius r= diameter/2= 2.5/2= 1.25in

Substituting we have

V= 1/3(3.14)*(1.25)²*9

V= 1/3*(3.14)*14.06

V= 44.156/3

V= 14.7in³

The volume of the cone is 14.7in³

Hence If 1 in³ of liquid costs $2

14.7in³ will cost $x

x= 14.7*2

x= $29.4

Based on the information given the amount of the initial investment is $8,361.

Let P represent the amount of the initial investment

Hence,

12855.94 = P(1 + .0431/12) ^12(10)

12,855.94=P(1+0.0035917)^120

12,855.94=P(1.0035917)^120

12,855.94=P(1.53760782)

P=12,855.94/1.53760782

P=$8,360.8

P=$8,361 (Approximately)

Inconclusion the amount of the initial investment is $8,361.

Transformations in geometry include translation, rotation, reflection, and dilation, which are used to change a figure's position, orientation, or size. The appropriate transformation to use depends on the changes observed between the purple pre-image and the white image in the problem.

In mathematics, specifically in geometry, we use transformations to move or change a figure in some way without altering its fundamental shape or size. The transformation of a pre-image onto an image can be achieved using transformations such as translation, rotation, reflection, or dilation.

To transform the purple pre-image onto the white image, firstly identify the type of transformation required. For instance, if the white image is the same size as the purple pre-image and only its position has changed, use translation. If the image is mirrored along a line, use reflection. If it's turned around a point, use rotation. If the image is an enlarged or reduced version of the original figure, use dilation.

Consequently, the precise steps depend on the type of transformation(s) required.

Answer:

16 times

Step-by-step explanation:

Since the sides are in the same ratio, i.e

1 : 4

The cylinders are similar

(Ratio of sides)² = Ratio of areas

4² = 16

Step-by-step explanation:

Step 1:  Make a ratio of the sides

Side of Cylinder A : Side of Cylinder B

            1                  :                4

Step 2:  Find the ratio of the area

[tex]1 : 4[/tex] ← Ratio of Side

[tex](1)^2 : (4)^2[/tex] ← Ratio of Area

[tex]1 : 16[/tex] ← Ratio of Area

Answer:  The area of Cylinder B is 16 times greater than Cylinder A

Answer:

gradient = 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the gradient and c the y- intercept )

Given

- 2x + y - 5 = 0 ( add 2x and 5 to both sides )

y = 2x + 5 ← in slope- intercept form

with gradient m = 2

Answer: A

Step-by-step explanation:

The first square is 22 inches on a side.

The second is 17.6 inches on a side

the third is 14.08 inches on a side.

We can suppose that we have a constant rate of decrease betwen the sides cubes, this means that:

22in*x = 17.6in

where x is the rate of scale.

x = 17.6/22 = 0.8

Now we test this with the second and third:

17.6in*0.8  = 14.08in

Ok, this works.

then the side of n-th cube can be found with the equation

L = 22*0.8^(n-1)

we can try the different options and see which one gives a value smaller than 10.

A) n = 5

L = 22*0.8^4 = 9.01

Then the correct option is A

You see which number is the greatest common factor (GCF)

Answer:

x = -1

y = 1

Step-by-step explanation:

Since it gives you "y", plug in the number given into the equation:

y = -6x - 5

1 = -6x - 5

Then, add 5 to both sides:

1 = -6x - 5

+5       + 5

________

6 = -6x

Divide both sides by -6:

6 = -6x

-1 = x

So now you have, x = -1 and y = 1

The value of [tex]\(\log 12\)[/tex] is approximately 1.0792 based on the given logarithmic values. Option B [tex]$\approx 1.0791$[/tex]

Let's evaluate the logarithmic expression [tex]\(\log 12\)[/tex]. We'll use the given logarithmic values:

1. Recall that [tex]\(\log 12\)[/tex] represents the common logarithm (base 10 logarithm) of the number 12.

2. Apply the change of base formula:

  [tex]\[ \log 12 = \frac{\log 12}{\log 10} \][/tex]

Given values:

[tex]- \(\log 12 \approx 2.4849\) (from \(\log 12\))[/tex]

[tex]- \(\log 10 \approx 2.3026\) (from \(\log 10\))[/tex]

Now calculate:

[tex]\[ \log 12 \approx \frac{2.4849}{2.3026} \][/tex]

[tex]\[ \log 12 \approx 1.0792 \][/tex]

Therefore, the value of [tex]\(\log 12\)[/tex] is approximately 1.0792.

The correct answer is b. [tex]\(\approx 1.0791\)[/tex].

Answer:

314ft²

Step-by-step explanation:

A = πr²

A= π10²

A=100π

A=100*3.14

A=314

Hope this helps :)

Final answer:

To calculate the area of the circular pool's surface, use the formula A = πr² with π approximated as 3.14 and the given radius of 10 feet. The area is 314 square feet, as the calculation yields A = 3.14 × 100, which does not need adjustment for significant figures.

Explanation:

To find the area of the surface of the water in the circular pool with a radius of 10 feet, we use the formula for the area of a circle, which is A = πr². Let's use the given value for pi (π) as 3.14 and the radius (r) is 10 feet. So the calculation is A = 3.14 × (10 feet)².

Now, squaring the radius, we get (10 feet)² = 100 feet². Next, we multiply this by our value for pi, resulting in A = 3.14 × 100 feet² = 314 feet². Therefore, the area of the surface of the water in the pool is 314 square feet.

Recalling significant figures, since our given radius was precise to two significant figures, our final answer should also reflect two significant figures. However, since all the numbers in 314 are significant, there is no need for adjustments in this case, and the result remains 314 square feet.

Answer:

12 inches

Step-by-step explanation:

W = 9 + L

WL = 252

L = 12

Answer:

l = 12

Step-by-step explanation:

Let l = length

width = l+9

The area of rectangle is

A = lw

A = l * (l+9)

252 = l^2 +9l

Subtract 252 from each side

0 = l^2 +9l -252

Factor

What 2 numbers multiply to -252 and add to 9

21*-12 = 252

21-12 = 9

0 = (l+21) (l-12)

Using the zero product property

l+21=0    l-12=0

l = -21     l = 12

We cannot have a negative length

l = 12

Answer:

Unknown side = 13 in

Step-by-step explanation:

If it is a right sided triangle, then you can use the Pythagoras theoreum.

unknown side = u

x² + y² = u²

12² + 5² = u²

u² = 144 + 25

u² = 169

u = + - SQRT(169)

{Only the positive value has a meaning}.

Unknown side = 13 in

Answer:

340

Step-by-step explanation:

As it was increased by 25%, $425 is 125% of the original price, so we can get back to 100% by dividing 425 by 5 [85], so 85 is 25% of the price. We can now get the original price by subtracting 85 from 425 (or you could multiply 85 by 4) which is 340

You can check this answer by multiplying 340 by 1.25

If the answer is 425, then it is correct, else, not. [it is]
