Total surface area is: 21 ft²
Lateral area is: 12π ft²
The total surface area of this cone is 21π square feet.
What is the total surface area of the cone?The total surface area of the cone is given by the following formula;
[tex]\rm Surface \ area=\pi r(r+l)[/tex]
Where h denotes the height of the cone and r is the radius and l is the slant height.
The radius of the cone = 3
The height of the cone = 4
Substitute all the values in the formula
[tex]\rm Surface \ area=\pi r(r+l)\\\\\rm Surface \ area=\pi 3(4+3)\\\\\rm Surface \ area=3\pi \times 7\\\\\rm Surface \ area=21\pi[/tex]
Hence, the total surface area of this cone is 21π square feet.

A local hotel has 158 rooms. Due to a scouting event, the entire hotel booked except for two rooms. If the girls scouts are using three times as many rooms as the boy scouts, how many rooms are the boy scouts using?
Answer:
39
Step-by-step explanation:
Let, total rooms girls booked be x and total rooms girls booked be y.
entire hotel was booked except two rooms.
so, total = 158-2 = 156
x+ y = 156
this is equation 1.
also, girls are using three times more room than boys.
so, y=3x
substituting y=3x in 1st equation,
x+ 3x = 156
or, 4x = 156
or, x= 156/4
x= 39

Answer:
D
Step-by-step explanation:
since it tells you y is=1 plug that into the top equation
-1=5x+4
-1=x
and you already have y=-1
so its(-1,-1)
this is simple
since y = -1
y = 5x + 4
-1 = 5x + 4
5x = -5
x = -1
therefore answer is (-1, -1)

What is the slope of the line that passes through the points (-2, 8)(−2,8) and (-22, 8) ?(−22,8)? Write your answer in simplest form.
Answer:
0Step-by-step explanation:
The slope of the line passing through two given points: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
(-2, 8) ⇒ x₁ = -2, y₁ = 8
(-22, 8) ⇒ x₂ = -22, y₂ = 8
So, the slope:
[tex]m=\dfrac{8-8}{-22-(-2)}=\dfrac{0}{-20}=0[/tex]

simplify: 10 (3x-4)=30-5x
Answer:
x=2
Step-by-step explanation:
10(3x−4)=30−5x
Step 1: Simplify both sides of the equation.
10(3x−4)=30−5x
(10)(3x)+(10)(−4)=30+−5x(Distribute)
30x+−40=30+−5x
30x−40=−5x+30
Step 2: Add 5x to both sides.
30x−40+5x=−5x+30+5x
35x−40=30
Step 3: Add 40 to both sides.
35x−40+40=30+40
35x=70
Step 4: Divide both sides by 35.
35x 70

During a hone run hitting contest Joe D hit 5 more home runs then ted w, ted w hit 8 more home runs then willie M. Altogether the three baseball players hit 105 hone runs, how many home runs did Ted W hit
Answer: 36
Step-by-step explanation:
Let Willie number of home run he represented by x.
Since ted w hit 8 more home runs than willie M, Ted home runs = x + 8
Since Joe D hit 5 more home runs than ted w, Joe D home run will be: = x + 8 + 5 = x + 13
Since they hit 105 home runs together, this will be represented as:
x + (x+8) + (x+13) = 105
x + x + 8 + x + 13 = 105
3x + 21 = 105
3x = 105 - 21
3x = 84
x = 84/3
x = 28
Number of Ted home run will be:
= x + 8
= 28 + 8
= 36
YOU JUST OPEN YOUR FIRST BUSINESS YOU HAVE RENT $1,000 YOUR FIRST ORDER OF PRODUCT WAS $10,000 YOU PHONE BILL IS $120 FOR 4 LINES, ELECTIRC BILL FOR THE FIRST MONTH IS $150, AND YOUR HEAT BILL IS $200 HOWEVER, SPRING IS NEAR SO YOU CAN CUT YOUR HEAT OFF.

Total costs are all the expenses that have to be paid by your business to keep it producing.
In this case that figure is:
Total cost = Rent + Phone bill + Electric bill + Heat bill + own salary + Wages

= $26,470
Paper clips are sold in boxes of 1000.
Each box costs £15.40
The table below shows the discount offered for large orders.
Ethan orders 5 boxes of paper clips.
Work out the amount of discount Ethan gets.
Answer:
6.5%
Step-by-step explanation:
1000 in a box and he orders 5 boxes.
1000x5= 5000
So he orders 5000 paper clips
1 box is £15.40 and he order 5, so £15.40x5= £77
£77 is between £55 and £79.99 so he will get 6.5% discount.
After the discount he will pay £71.99
