The recipe makes 8 pancakes.
He wants to make 12 pancakes.
First, find out how many times what he needs is compared to the recipe.
He wants 12 pancakes; the recipe makes 8 pancakes.
12/8 = 1.5
He wants to make 1.5 times the recipe.
Now multiply every ingredient amount by 1.5 to find what he needs to make 12 pancakes.
240 g of plain flour.
240 g * 1.5 = 360 g of plain flour
2 egs
2 eggs * 1.5 = 3 eggs
600 ml milk
600 ml * 1.5 = 900 ml
Answer: 360; 3; 900
1/4 of 1 minute would be 1/4 * 60(seconds in a minute)
so that would be 60/4=15 seconds.
X^2+10x+29=0
Quadratic Formula:
−b±√b^2−4(ac)/2a
Substitute the values :
a=1, b=−10, and c=29
into the quadratic formula and solve for
x.
10±√(−10)^2−4•(1•29)/ 2•1
Simplify.
Answer: x=5±2i
50 bc since all the angles in a triangle are 180 degrees the other angle in the complete triangle is 40 degrees and since the lines are parallel it would be a corresponding angle to the angle beside x, then you would take 90+40 +x= 180 bc it’s a straight angle
you would get 50
ANSWER:
<u>On solving equation by quadratic formula method, we get</u>
D = b² – 4ac
- (–5)² – 4 × 1 × 3
- 25 – 12
- 13
D > 0, so it has real roots.
Now, x = – b ± √D/2a
So, <u>Correct choice</u> - [A] & [C].
