Okay so the first thing you for for is to see if you can reduce your numbers and you can in this problem. You can reduce the 8 and 12 by 4, meaning that you can divide them by 4. So your problem would now be 2x7/3. Now to calculate your product you just times 2x7 and you’re answer is 14/3 :)
7.5cm
lets take point K represent lenght from M to perimeter of circle.
r is radius
KM= r-OM= r-4.5cm
now lets draw line from O to A (OA)
we get triangle.
hypotenuse is OA and it equals r(radius)
ab=12 cm. so another side of the triangle (AM) is 12/2=6cm. and the last side of the triangle is 4.5(OM)
use pythaghorean theorem
squares of sides added = square of hypotenuse
20.25+36=r^2(our hypotenuse is radius)
56.25=r^2
r=√56.25=7.5cm
90 grams are equivalent to 0.09 kilograms and 55 grams are equivalent to 0.055.
So 0.09 + 0.055 = 0.145.
0.145 * 12 = 1.74
So 1.74 kilograms of sugar is needed to make 12 crisps.
Answer:
D)
Step-by-step explanation:
I think that the response is d), because there is only a single path between any 2 nodes. Like in a tree, a leaf cannot belong to 2 branches.
