If you multiplied the equation by 2 it's gonna be 2x^2-12x-24=0 which is the same if you factor it as <span>x^2-6x-12=0</span>
Answer:
3927 cm² wrapping paper will be required.
Step-by-step explanation:
Lateral surface area of a cone shaped wrapper = πrl
where, r = radius of the waffle cone
and l = slant height of the cone
It has been given in the question, radius 'r' = 5cm
and lateral height 'l' = 10 cm
Lateral surface area of the cone = π(5)(10)
= 50π
= 157.08 cm²
If they plan to make 25 waffles then wrapper paper required
= 25×157.08
= 3927 cm²
Therefore, 3927 cm² wrapping paper will be required.
Answer:
Question 2
x is approximately 15.038 or 15 days
Question 3
$3.41
Question 4
31.1
Step-by-step explanation:
Question 2
5.2 km/1 day =78.2 km/x days
Multiply both sides by x
5.2x=78.2
divide by 5.2
x is approximately 15.038
or 15 days
Question 3
350-(262.94+83.65)
$3.41
Question 4
22(1.3)+2.5
31.1 m
Step-by-step explanation:
A straight line adds up to 180°
m+3m=180°
4m=180°
m=45°
3m=45°
angle CBD=3(45)
=135°
The answer
<span>the third rope to counterbalance Sam and Charlie is F
and vectF +vectF1 +vectF2 =vect0
let's consider axis
y'y </span>vectF = -F
vectF 1= F1cos60
vectF 2= F2cos45
-F = -F1cos60-F2co45
so F= F1cos60+F2co45= 350x0.5+400x0.7=457.84 pounds
