In a sale, normal prices are reduced<br> by 25%.<br> The sale price of a calculator is<br> £8.82

Lelu [443]

Answer:

2.2050

Step-by-step explanation:

25% -> 2500.

25% is just a way of saying 25 out of 100. So we have to times 25 by 100 which gets you 2500. You the have to multiply 2500 by 8.82 which will get you 22050. Now the price is reduced by 25% so the answer will be less than 8. You have to add a decimal somewhere in the number 22050 and it has to be less than 8. You could but it after the second 2 but then it will be over 8. So the only spot you can put it is after the first 2 like this 2. so the answer will be 2.2050

Of the $2400 Mr Calvin earned, he spent 3/8 on food, 1/3 on taxes and 1/6 on other expenses. Find out how much all this is in do

sattari [20]

Answer: $300

Step-by-step explanation:

Mr. Calvin earned $\$2400$

He spent $\frac{3}{8}$ on food i.e.

$\Rightarrow \dfrac{3}{8}\times 2400=\$900$

$\dfrac{1}{3}\quad \text{on taxes i.e.}\\\\\Rightarrow \dfrac{1}{3}\times 2400=\$800$

$\dfrac{1}{6}\ \text{on other expenses i.e.}\\\\\Rightarrow \dfrac{1}{6}\times 2400=\$400$

Remaining money = $2400-900-800-400=\$300$

So, he saved $300 after expenses

What is the value of X

klemol [59]

Answer:

x ≈ 23.31

Step-by-step explanation:

We can use the law of cosines because we know 2 sides and 1 angle.

The general formula for the law of cosines if the triangle sides are a, b,c and α is the angle between sides a and b. c is the missing side.

$c = \sqrt{a^{2} +b^{2} -2*a*b* cos \alpha }$

In our problem the law of cosines is

x = $\sqrt{21^{2} +13^{2} - 2*21*13 *cos 83}$

x ≈ 23.31
