Answer:

1288

Step-by-step explanation:

Triangles on the top have surface area 15*14/2 there are four of them so multiply by four to get 420.

The rectangular sections all have area 12*14 except for the base. There are four of these equal sections, so the combined area is 672.

Lastly, the base has area 14*14, which is 196.

Summing all of these we get 1288

Tina has been dieting for a total of 13 weeks she lost 3 pounds on the first week of her dad but gain back a pound on the second

natima [27]

So Tina has been dieting for 13 weeks

On week 1: She lost 3 pounds, so +3 pounds

On week 2: She gained a pound, so - 1 pound

On each remaining week, she lost 2 pounds, so,

On week 3: She lost 2 pounds, so +2 pounds

On week 4: She lost 2 pounds, so +2 pounds

On week 5: She lost 2 pounds, so +2 pounds

On week 6: She lost 2 pounds, so +2 pounds

And so on,,,

So losing 2 pounds each week for 11 weeks would equal, 2 pounds x 11 weeks = 22 pounds

So, add that all up: 3 pounds - 1 pound + (2 x 11 weeks) = 24 pounds total

How to find cp if loss and sp are given

velikii [3]

Step-by-step explanation:

$\tt{ \: H \: E \: Y \: \: T \: H \: E \: R\: E \: }$ !

When Loss and Selling price ( SP ) are given , Cost price ( CP ) can be found out using the following formulae :

✰ $\large{ \boxed{ \boxed{ \tt{CP = Loss + SP}}}}$

$\text{How \: did\: we \:get \:the \: formula : \: CP \: = Loss \: + \: SP} \:$ ?

We simply derived the formula from Loss = CP - SP.

First , Swap the sides of the equation :

⟶ $\text{CP - SP = Loss}$

Move SP to right hand side and change it's sign :

⟶ $\text{CP = Loss + SP}$

This is how , CP can be obtained when we are given loss and SP.

Hope I helped ! ♡

Have a wonderful day / night ! ツ
