This function is in the form y=mx + b where m is your slope, so the slope is -2
Answer:
x = 6 and the +4x is wrong
Step-by-step explanation:
2x + 4x + 4 = 4(x + 4)
6x + 4 = 4x + 16
+4x +4x <--( <u>This part is wrong</u> )
10x + 4 = 16
-4 -4
10x = 12
10 10
x = 1.2
Correct steps
2x + 4x + 4 = 4(x + 4)
6x + 4 = 4x + 16
-4x -4x
2x + 4 = 16
-4 -4
2x = 12
2 2
x = 6
I think it’s either D or A,
So sorry if I’m wrong
Answer:
1. 39
2. 15
3.329
4. 16
5. 300
Step-by-step explanation:
Just divide the first two numbers and then multiply the quotient by the last number. You'll be ok, you've got this, keep your head up!
1. 52/4 = 13 and 13 x 3 = 39
2. 45/9 = 5 and 5 x 3 = 15
3. 470/10 = 47 and 47 x 7 = 329
4. 10/2.5 = 4 and 4 x 4 = 16
5. 125/2.5 = 50 and 50 x 6 = 300
Answer:
(1 ) Inner curved surface area of the well is 109.9 sq. meters.
(2) The cost of plastering the total curved surface area is 4396.
Step-by-step explanation:
The inner diameter = 3.5 m
Depth of the well = 10 m
Now, Diameter = 2 x Radius
⇒R = D/ 2 = 3.5/2 = 1.75
or, the inner radius of the well = 1.75 m
CURVED SURFACE AREA of cylinder = 2πr h
⇒The inner curved surface area = 2πr h = 2 ( 3.14) (1.75)(10)
= 109 sq. meters
Hence, the inner curved surface area of the well is 109.9 sq. meters.
Now, the cost of plastering the curved area is 40 per sq meters
So, the cost of total plastering total area = 109.9 x(Cost per meter sq.)
= 109.9 x (40)
= 4396
Hence, the cost of plastering the total curved surface area is 4396.
