Answer:
f = 8
Step-by-step explanation:
21 + 5f = 61
5f = 61 - 21
f = (61 - 21) / 5
f = 8
Answer:
x+y = 50
Step-by-step explanation:
We can find the slope of the line
m = (y2-y1)/(x2-x1)
= (50-41)/(0-9)
= 9/-9
=-1
We can use the point slope form of the equation to make an equation for a line
y-y1 = m(x-x1)
y-50 = -1(x-0)
y-50 = -x
To get it in standard from, subtract y from each side
y-y-50 = -x-y
-50 = -x-y
Multiply each side by -1
50 = x+y
x+y = 50
What is being asked here is to convert the value above from units of yards per second into miles per hour. To do this, we need a conversion factor to multiply to the value for it to be converted to another units. We do as follows:
Conversion Factors
1 mile = 1760 yards
1 hr = 3600 s
<span>3 yd/s ( 1 mile / 1760 yards ) (3600 s / 1 hr) = 10.8 miles per hour</span>
Answer:
72
Step-by-step explanation:
you multiply the length and the width
He paid $1800 a month for 12 months 150 times 12 equals $1800 so the answer is $1800
