Answer:
True
Step-by-step explanation:
2(x+3) = 5x+6-3x
2x+6=5x-3x+6
2x+6=2x+6
Answer:
(i) The surface(sheet) of a conical tent is circular so we must use the formula for the area of a circle to find out;
Given the diameter 14, we must find the radius.
To find the radius we must do 1/2 of the diameter to get the radius.
14 x 1/2 = <u>7</u>, is the radius
Formula for area of a circle;
a = πr^2
where pi is 3.14 or 22/7, r is the radius which is being squared
Plug in the actual values:
a = πr^2
a = 3.14 x 7^2
a = 3.14 x 49
a = 153.86 square meters, is the area of the conical tent's sheet.
(ii) Since there are 153.86 meters in one sheet, we should multiply that by $12(because $12 per meter) to get the total cost.
So,
153.86 meters x $12 = $1,846.32, it would cost 1,846.32 dollars.
Answer:
D
Step-by-step explanation:
you use the Pythagorean theorem
It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
so mathematically
a2+b2=c2
a and b being the short sides and C being the Hypotenuse
so in our case
a= 10 cm
b= ?
c= 18
a2+b2=c2
(10cm)2+(b)2=(18cm)2
100cm2+b2=324cm2
b2=324cm2-100cm2
b2=224cm2
*putting both sides under a square root*
b=4sqrt14cm
Answer:
S(n)=[50]
Step-by-step explanation:
52-2=50
so the S(n)=50
