8. If 5/12.5 is equivalent to -4/2x, what is the value of x?

egoroff_w [7]

Answer:

-5

Step-by-step explanation:

$\frac{5}{12.5} = \frac{-4}{2x}$

$5 \cdot 2x = 12.5 \cdot -4$

$10x = -50$

$x=-5$

PLEASE HELP WILL GIVE BRAINLIEST AND 20 POINTS

15 inches.

The side length of the base is 4. Find the surface area of the base only by squaring the side length - 4² - which is 16. The surface area of the base is 16 in².

The surface area of the entire pyramid can be found using this equation:

$SA = B + \frac{1}{2} nbl$

Where:
- SA is the surface area (136 square inches)
- B is the area of the base (16 square inches)
- n is the number of triangles (4, because it's a square pyramid)
- b is the base length (4 inches)
- l is the slant length

Note that we have many parts of this equation, and all we need is the slant length. So, let's format the equation with what we have:

$136 = 16 + \frac{1}{2} * 4 * 4 * l$

So then we want to solve for l, the slant height. So, start by subtracting 16 from each side. This would give us:

$120 = \frac{1}{2} * 4 * 4 * l$

Now, multiply both sides by 2 to get rid of the fraction:

$240 = 4 * 4 * l$

Finally, divide both sides by four, twice (divide by 16):

$15 = l$

So, we know that the slant height of this pyramid is 15 inches.

Write 30 in equality to describe this graph show your work will mark brainiest

Paul [167]

Well a closed circle means greater than or less than or equal to. This means that if x which is the number we dont know, is higher than 5 than we can say that x is greater than or equal to 5. I cannot draw it on a computer so that is it.

A godown is 40m long,30m wide and 9m high. How many cuboidal boxes can be stored in it, if the dimension of each box is 2mx1.2x4

sergiy2304 [10]

Answer: There are 10000 cuboidal boxes can be stored in the godown.

Step-by-step explanation:

Since we have given that

Dimensions of godown will be

40 m, 30 m, 9 m .

Dimensions of cuboidal boxes will be

2 m, 1.2 m, 45 cm

As we know Number of cuboidal boxes is given by

$\frac{\text{ Volume of godown }}{\text{ Volume of cuboidal box}}\\\\=\frac{40\times 30\times 9}{2\times 1.2\times 0.45}\\\\=10000$

Hence, there are 10000 cuboidal boxes can be stored in the godown.
