I don’t know what the answer is but I just came by to say I hope you have a great day
Answer:
Step-by-step explanation:
Height of wall = 10ft
Length of ladder = 12ft
Angle of elevation be x
Sin x = opp/hyp
Sin x = wall height/length of ladder
Sin x = 10/12
Sin x = 0.83
X = Sin-¹ (0.83)
X = 56.44°
Answer:
The relationship between x, Danielle's total sales for the month, and y, her monthly income is as shown;
y=0.06 x+500
Step-by-step explanation:
Step 1: Express the monthly income
The monthly income can be expressed as follows;
y=F+(R×x)
where;
y=her monthly income
F=fixed income per month
R=commission rate
x=total number of houses she sells
In our case;
Monthly income=y
F=$500 a month
R=6%=6/100=0.06
total number of houses she sell=x
replacing;
y=500+(6% of x)
y=500+(0.06×x)
y=500+0.06 x
The relationship between x, Danielle's total sales for the month, and y, her monthly income is as shown;
y=0.06 x+500
For every one second that goes by he is gaining 2 meters. So you need you last one know meter plus two for every second.
Let width = x ft then
2x + 2(2x) = 42
6x = 42
x = 7
so the width is 7 ft and length is 14 ft.
So the cost to build the pen = 14*1.25 + 14*1,25 + 7*2.50 + 7*2.50
= 70 answer
