The length of the measure of YZ is 80cm
<h3>Perpendicular lines</h3>
Perpendicular lines are lines that are at angle 90 degrees to each other. From the given diagram;
WX = 82cm
Required
Length. of YZ
Using the pythagoras theorem
YV = VZ = √41²-9²
YV = VZ = √1600
YV = VZ = 40
Since YZ = YV + VZ
YZ = 40cm + 40cm
YZ= 80cm
Hence the length of the measure of YZ is 80cm

Answer:
92 inches
Step-by-step explanation:
When a tire's size = P220/65 R 18, it means that:
- the rim is 18 inches wide (or 457 millimeters)
- the width of the tire is 8.7 inches (or 220 millimeters)
- the sidewall of the tire is 5.65 inches (or 144 millimeters)
- the 65 shows the relationship between tire width and sidewall (65%)
the total diameter of the tire = 5.65 + 18 + 5.65 = 29.3 inches
the circumference = 2 x π x radius or diameter x π = 29.3 x 3.141592 = 92 inches
Answer:
b= 10 miles/hr and c= 5 miles/hr
Step-by-step explanation:
Let it's downstream and upstream speed be d and u respectively
also speed of the boat be b and speed of stream be c.
as per question d = 150/10= 15 miles/hr
and, u= 150/30= 5 miles/hr
also we know d= b+c = 15.....i and u = b-c= 5....ii
solving i and ii we get b= 10 miles/hr and c= 5 miles/hr
Answer:
$120.
Step-by-step explanation:
The amount he sells the tool kit for = 80 + 20% of 80
= 80 + 16
= $96.
Let m be the marked price, then
m - 0.20m = 96
0.8m = 96
m = $120.
Y=-3x+23
distribute -3, get y alone (add 2 to both sides)
