The total cost for snowboarding is $124 because: 32 + 54 + 38 = 124
Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form 
or 
Let
x-----> the speed of the elevator
y----> the weight it carries
so
<em>Find the constant k</em>
For x=10 ft/sec, y=400 lb
substitute
The equation is
Find the speed for y=500 lb
substitute in the equation
Zach bought his shoes for $39.
Austin bought his shoes for $48.
So, Austin paid $9 more for his shoes than Zach did.
Answer:
m<ADC = 107
Step-by-step explanation:
You need to know three things to solve this problem.
1) Opposite angles of an inscribed quadrilateral are supplementary.
2) The measure of an inscribed angle is half the measure of its subtended arc.
3) The sum of the measures of all the arcs of a circle is 360 deg.
From 1) we get:
m<A + m<C = 180
72 + m<C = 180
m<C = 108
From 2) we get:
m<C = (1/2)m(arc)BAD
108 = (1/2)[m(arc)AB + m(arc)AD]
216 = m(arc)AB + 122
m(arc)AB = 94
From 3) we get:
m(arc)AB + m(arc)BC + m(arc)CD + m(arc)DA = 360
94 + 120 + m(arc)CD + 122 = 360
m(arc)CD = 24
From 2) we get:
m<ADC = (1/2)m(arc)ABC
m<ADC = (1/2)[m(arc)AB + m(arc)BC]
m<ADC = (1/2)[94 + 120]
m<ADC = 107
Answer: x=11/2
Step-by-step explanation: (4x-5)+15=32
4x-5+15=32
4x+10-10=32-10
4x/4=22/4
x=11/2
