If their perimeters are equal, we can add up all the side lengths of each triangle, and set the perimeters equal to each other to find the value of x that satisfies the equation:

x - 2 + x + 3x + 1 = 2x - 5 + x + 4 + 6x - 7

Combine like terms:

5x - 1 = 9x - 8

And finally, solve for x:

7 = 4x

x = \frac{7}{4}

Therefore, x is equal to \frac{7}{4}.

<em>Hope this helps! :)</em>

The volume V of a right‑circular cylinder is computed using the values d = 3.1 m for the diameter and h = 6.6 m for the height.
pantera1 [17]

Answer:

6%

Step-by-step explanation:

A function f(x) can by approximated at and around a point, say x = a by,

f(x) = f(a) + f'(a)(x-a)

where,  f'(x)=\frac{df}{dx}

Here, volume V is a function of radius r and height h. In the 2 dimensional case, we have to take the partial derivatives.

Given,

V=\pi r^2h

or, dV=\frac{\partial V }{\partial r}dr+ \frac{\partial V }{\partial h}dh

at r = 1.55 m and h = 6.6 m

dr=0.02\times1.55m=0.031m

dh=0.02\times6.6m=0.132m

\frac{\partial V }{\partial r}=2\pi r h=2\pi \times 1.55\times 6.6=64.277

\frac{\partial V }{\partial h}=\pi r^2=7.5477

Therefore, dV=(64.277\times.031)+(7.5477\times0.132)=2.9889m

Also, V=\pi r^2h=49.8147m

Hence, maximum error is given by,

R=\frac{2.9889}{49.8147} \times 100

= 6%

One leg of a right triangle measures 10 inches while the other leg measure square root of 21 inches. What is the length of its h
sladkih [1.3K]

Answer:

11 inches

Step-by-step explanation:

hypotenuse² = leg₁² + leg₂²

                     =10² + (√21)²

                    = 100 + 21

                    = 121

Hypotenuse = √ 121 = √11*11 = 11 inches

(I meant to make this category be science but I accidentally clicked math)
Mekhanik [1.2K]

Answer: Physical weathering is when the physical structure of something is broken down..fast moving water is an example of this because it physically changes the structure of rocks over time. Chemical weathering is the erosion of materials from chemical reactions. Chemical weathering occurs more on a molecular level. An example of chemical weathering is when the minerals in rocks are dissolved by water, which creates a new compound

Hope this makes sense and helps!
