3 0

8/12 divide by 4 top and bottom
4/6 skipping this step
2/3 to get to here

26/x this is the end number we want

26/39 here it is multiplying the number making the number equal to the 2/3

Question 1 1.1 Jane wants to make Spaghetti Bolognese for her family of 5 people, including herself. The following is a list of

Lelechka [254]

Answer:

$\begin{gathered} 1.1.1.300g\cdot\frac{0.001\operatorname{kg}}{1g}=0.3\operatorname{kg} \\ 1.1.2.400g\cdot\frac{0.001\operatorname{kg}}{1g}=0.4\operatorname{kg} \\ 1.1.3.500ml\cdot\frac{0.001lt}{1ml}=0.5\text{ lt} \\ 1.1.4.769.69\cdot0.001=0.769\text{ liters} \end{gathered}$

Step by step explanation:

1.1.1 We know that 1kg is equivalent to 1000g, then we can convert:

$300g\cdot\frac{0.001\operatorname{kg}}{1g}=0.3\operatorname{kg}$

1.1.2 For 400g of tomatoes:

$400g\cdot\frac{0.001\operatorname{kg}}{1g}=0.4\operatorname{kg}$

1.1.3. For 500ml of water, convert this into liters. We know that a 1ml is 0.001 lt

$500ml\cdot\frac{0.001lt}{1ml}=0.5\text{ lt}$

1.1.4. Since capacity is represented by the following expression:

$\begin{gathered} C=\pi\cdot\text{radius}\cdot\text{radius}\cdot\text{height} \\ C=\pi\cdot7\cdot7\cdot5=769.69cm^3 \end{gathered}$

We know that 1 cubic centimeter is equal to 0.001 liters.

$769.69\cdot0.001=0.769\text{ liters}$

1)cot a/2 -tan a/2 = 2 cot a<br>2) cot b/2 + tan b/2= 2 cosec b<br> prove

VladimirAG [237]

1)

LHS = cot(a/2) - tan(a/2)

= (1 - tan^2(a/2))/tan(a/2)

= (2-sec^2(a/2))/tan(a/2)

= 2cot(a/2) - cosec(a/2)sec(a/2)

= 2(1+cos(a))/sin(a) - 1/(cos(a/2)sin(a/2))

= 2 (1+cos(a))/sin(a) - 2/sin(a)) (product to sums)

= 2[(1+cos(a) -1)/sin(a)]

=2cot a

= RHS

2.

LHS = cot(b/2) + tan(b/2)

= [1 + tan^2(b/2)]/tan(b/2)

= sec^2(b/2)/tan(b/2)

= 1/sin(b/2)cos(b/2)

using product to sums

= 2/sin(b)

= 2cosec(b)

= RHS
