Answer:

172.70 sq. ft.

Step-by-step explanation:

The surface area of a circular cone is

SA = \pi r^{2} + \pi rl       r = radius of base         l = slant height

r = 4.4    and     l = 8.1

SA = 3.14 (4.4^{2}) + 3.14(4.4)(8.1)\\

SA = 3.14(19.36) + 111.9096

     = 60.7904 + 111.9096

     = 172.70 sq. ft.

Mr.bonds math class starts at 11:30 if the class ends at 1:00 how long is his teaching.
Irina-Kira [14]
11:30 and 1:00
assuming that it is
11:30 AM to 1:00 PM and not 11:30 AM to 1:00 AM

11:30 to 1:00 cannot be directly counted
the hours go like  this
1,2,3,4,5,6,7,8,9,10,11,12=AM
then after 12AM then
1,2,3,4,5,6,7,8,9,10,11,2=PM

60 minutes in 1 hour so
11:30=11 hours and 30 mins
how far to 12 AM?
12 AM=12 hours=11 hours and 60 minutes
11 hours and 60 minutes-(11 hours and 30 mins)=30 minutes

then from 12 AM to 1 PM=1 hour so
time total difference is 1 hour and 30 minutes

pickupchik [31]

Answer:

a) 55 degrees

b) 350 ft.

Step-by-step explanation:

a- the sum of angles of triangle=180

( since it is right angle , one angle is 90 degrees), x be the acute angle

x+35+90=180

x=180-125

x=55 degrees

b) tan 35= height of a tree/ length of a shadow

height of a tree=tan35*500=350.103≅350 ft ( rounded to nearest tens)

c)  hypotenuse²=350.1²+500²

c=√350.1²+500²

c=610.385 ft

d) no because the distance is more than 500

Please help me and I’ll give you brainiest make sure to explain :)
Korolek [52]

Answer:

1. So, it's basically y=mx + b, you put the b first like y= 2/3x -1, and the b is negative, so you go down on the y-axis one time and the 2/3x is rise over run 2 is the rise and 3 is the run.

for y=-x -4 you put a denominator for -x like -1/1x you keep the denominator positive.

2. If the 2x is in the incorrect spot you put it on the other side and it's a positive, so you put is as a negative on the other side, so you're left with

-y=-2x-1, but you can't have a sign on them, so you divide it with -1 and on the other side as well, so it comes down to y=2x+1 and if the x doesn't have a denominator you add a one to it, like this y=2/1x+1 and you put the 1 on the y-axis and its a positive so you go up one time and the rise or run is 2/1, so you start at 1 on the y-axis and you rise 2 times, so 3-axis and run 1 time and it's 1-axis.

For the last one ill do it on paper.
