9/16x = 3/4 how do you do it if you’re solving for x

Mathematics

Answer:

$x=\frac{3}{4}$

Step-by-step explanation:

Whenever we have 2 fractions equal to each other, we first cross multiply, then take variables to one side and numbers to other side and use basic algebra to solve for the variable [here, it is x].

The process is shown below:

$\frac{9}{16x}=\frac{3}{4}\\9*4=16x*3\\36=48x\\x=\frac{36}{48}=\frac{3}{4}$

So, x = 3/4

Can someone help with this asap

Radda [10]

Answer:

There are 5⁸ blades.

Step-by-step explanation:

Given that,

The area of land $=5^{12}\ \text{acres}$

Each acre has 5⁴ blades of grass

We need to find how many blades of grass have by the entire land. It can be calculated as follows :

$n=\dfrac{5^{12}}{5^4}\\\\n=5^{12-4}\\\\n=5^8$

Hence, there are 5⁸ blades.

The perimeter of an equilateral triangle is 12\/3 cm. Find the radius, apothem and area of the equilateral triangle.

Irina-Kira [14]

Answer:

Radius - 4

Apothem - 2

Area - $12\sqrt{3}$ or 20.8

Step-by-step explanation:

Try to draw out my explanation so you know what this looks like.

~~~~

This is an equilateral triangle, so all sides are the same length. The perimeter can be divided by 3 to get each side length...

$12\sqrt{3} \div3 = 4\sqrt{3}$

Now that we know the side lengths, we can get this started!

~~~~

Now, an equilateral triangle has angles that all equal 60 degrees. We can bisect this into TWO special case triangles of measures 90-60-30.

4 times the square root of 3 will be the hypotenuse, and the smallest leg is always half of that. The larger leg is represented as the small leg times the square root of 3.

$Small=2\sqrt{3} \\Hypotenuse = 4\sqrt{3} \\Long =6$

By the way, the formula for the area can be either of the two:

$A= \frac{1}{2} bh\\or\\A = \frac{1}{2} NAS$

we can easily find the area using the first formula.

$A= \frac{1}{2} (4\sqrt{3} )(6)\\A=12\sqrt{3}$

The radius is the distance from the center to the corners & the apothem is the distance from the center to a side...

So we can divide the big triangle into a mini triangle at the bottom left/right

The height (small leg) of that triangle would be the apothem

The hypotenuse of that triangle would be the radius.

I did the math really quick because this is getting long. Anyhow, the small leg is 2 so is the apothem, and the hypotenus is 4, so is the radius

Happy April Fool's btw, lol.
