Answer: Dark Chocolate = 2.5 lbs, Milk Chocolate = 0.5 lbs
<u>Step-by-step explanation:</u>
Qty % Qty * %
Dark Chocolate: x 0.25 0.25(x) = 0.25x
Milk Chocolate: <u> 3 - x </u> 0.75 0.75(3 - x) <u>= 2.25 - 0.75x</u>
Mixture: 3 100% = 1
Part A: 0.25x + 2.25 - 0.75x = 1
2.25 - 0.50x = 1
<u> -2.25 </u> <u> -2.25 </u>
-0.50x = -1.25
<u> ÷ -0.50 </u> <u>÷ -0.50 </u>
x = 2.5
Milk Chocolate: 3 - x = 3 - 2.5 = 0.5
Answer:
5 cakes
Step-by-step explanation:
13 1/3 ÷ 2 2/3
40/3 x 3/8
= 5 cakes
Answer:√5 - √2
Step-by-step explanation:
= √(5 + 2 - 2√10 )
= √{(√5)² +(√2)² - 2.√5.√2}
= √(√5 - √2)² (by identity a² + b² -2ab = ( a-b)²)
= √5 - √2
Answer:
2nd option
Step-by-step explanation:
given an exponential function in the form y = a
to find a and b use the coordinate points it passes through
using (0, 4 ) , then
4 = a [ = 1 ] , that is
a = 4 , so
y = 4
using (2, 100 )
100 = 4b² ( divide both sides by 4 )
25 = b² ( take the square root of both sides )
= b , that is
b = 5
then exponential function is
y = 4 .
