What is the value of m in the figure below?
Elena L [17]
<h3>Answer:  8.2 (choice B)</h3>

==========================================================

Explanation:

First we'll need the length of segment BD, which I'll call x for now. The similar triangles allow us to set up the proportion below to solve for x

AD/BD = BD/DC

13/x = x/4

13*4 = x^2

52 = x^2

x^2 = 52

x = sqrt(52)

Segment BD is exactly sqrt(52) units long.

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

Now focus your attention on triangle BDC. We'll use the pythagorean theorem to find BC

(BD)^2 + (DC)^2 = (BC)^2

( sqrt(52) )^2 + ( 4 )^2 = ( m )^2

52 + 16 = m^2

68 = m^2

m^2 = 68

m = sqrt(68)

m = 8.2462 approximately

m = 8.2

Twice the difference of a number and 5 is 7​
zysi [14]
The difference of a number and 5 = n - 5

Twice that = 2(n - 5)


‘is’ is the equal sign, so the expression before is equal to 7.


Equation: 2(n - 5) = 7

A countertop is 16 feet long and 3 feet wide. what is the area of the countertop in square meters.
Mrac [35]
Area=legnth times width
legnth=16 ft
width=3 ft
but wait, they want the area in squazre METERS
so convert feet to meters
1 foot=0.3048 meters

convert 16 feet and 3 feet to meters

16 feet=16 times 0.3048=4.8768
3 feet=3 times 0.3048=0.9144

so the area is now
legnth=4.8768 m
width=0.9144m

area=4.8768 m times 0.9144 m=4.45934592
round

answer is 4 square METERS
