Answer:

<h2><u><em>9 mm</em></u></h2>

Step-by-step explanation:

A triangle has a height of 6mm and an area of 27mm2. What is the length of the base of the triangle?

----

To calculate the area of a triangle, multiply the height by the width (this is also known as the 'base') then divide by 2.

We use the inverse formula

base = 2A : height

2 * 27 : 6 = 9

------------------------

check

6 * 9 : 2 = 27

the answer is good

A rope 8 feet long is cut into two pieces. One piece is used to form a circle and the other used to form a square. Find a functi

shtirl [24]

<span>1st piece: x feet
2nd piece: 8-x feet
--------------------------
Use the "x" piece to form a circle:
Circumference = "x".
2(pi)*radius = x

radius = x/(2pi)
So, Area = pi[x/(2)]^2 = x^2/(4pi) = (1/4pi)x^2
=========================================================
Use the 10-x piece to form square:
side = (1/4pi)(10-x)
Area = side^2 = (1/16)(10-x)^2

Hope this helps! :)</span>

Step-by-step explanation:

This is a right triangle with two congruent angles. so this is a isoceles right triangle or called a

45-45-90 triangle. This means that the legs are equal to each other so

$3(x + 2) = 24$

$3x + 6 = 24$

$3x = 18$

$x = 6$

Mrs. Miller wants to estimate the widths the steps in front of her house . Best bench mark for her to use is ?

Arisa [49]

The best bench mark to use is an inch. She should use an inch because centimeters are too small and the steps might be less than a foot.
