u=2

Answer:

Solution given:

<h3>Relationship between base and hypotenuse is given by cos angle.</h3>

Cos 45°=base/hypotenuse

$\frac{1}{\sqrt{2}}=\frac{\sqrt{2}}{u}$

doing crisscrossed multiplication

$\sqrt{2}*\sqrt{2}=1*u$

u=2

Answer:

u = 2

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj side / hypotenuse

cos 45 = sqrt(2) / u

u cos 45 = sqrt(2)

u = sqrt(2) / cos 45

u = sqrt(2) / 1/ sqrt(2)

u = sqrt(2) * sqrt(2)

u =2

First one gram equals 1000 grams, so a 39 kilogram equals 39000 grams. Then, 1000 pillows times 300 equals a 39 kilogram sofa. I

jolli1 [7]

Answer:

Step-by-step explanation:

Kilogram is the unit of weight. Kilogram is the measure of how much matter or the mass an object has in it. Kilogram is the bigger unit of measurement while gram and milligram are the smaller units to measure the weight of any object.

We know,

1 kilogram = 1000 gram x 1

So, 1000 gram is equal to 1 kilogram

That means, 39,000 gram is equal to 39 kilogram.

In the question it is asked whether 1000 pillows times 300 is equal to 39 kilogram sofa or not.

The answer is not correct, because we do not know the weight of the 1000 pillows.

And also, 1000 x 300 will give you 300,000 and not 39 kilogram or 39,000 grams.

5. a) A business company made a profit of Rs 24,00,000 in the last year. The management decided to distribute 20 % bonus from th

viva [34]

Answer:

a) = Rs 16000

b) = 5%

c) = Rs 30,000,000

10% = 24,000,00/10 = Rs 240,000

20% = 240,000 x 2 = Rs 480,000

480,000/30 = Rs 16000

b) The bonus percentage needs to be increased by 5%

explanation:

Since every worker needs Rs 20000 we need to times it by 30

20000 x 30 = Rs 600,000

600,000 - 480,000 = Rs 120,000

Now we need to find the percentage of Rs 120,000

10% = Rs 240,000

5% = 240,000 divide by 2 = Rs 120,000

This is the best I can do for now please let me know if you understood the answer!

Rob spent 25\%25% more time on his research project than he had planned. He spent an extra hh hours on the project.

MatroZZZ [7]

Answer: 5h represents the number of hours Rob actually spent on the project.

Step-by-step explanation:

Let Rob planned that he will spend x hours in his project.

According to the question,

He spent 25% more time on his project than he planned.

That is, his actual time = x + 25% of x = 125% of x

Again according to the question,

He spent an extra h hours on his project.

That is, 25% of x = h

$\frac{25\times x}{100} = h$

$x=\frac{100h}{25}$

x = 4h

Thus, his actual time = 125% of x = 125% of 4h = $\frac{125\times 4h}{100}$ = 5h

Which is the required expression.
