Answer: I think the problem is telling you to add the fractions, so 4/50 + 3/5 = 34/50 which simplifies to 17/25

Step-by-step explanation: First in order to add the fractions, you need to make the both of the fractions denominators the same. So 5*10=50, and whatever you do to the bottom you have to do to the top, so 3*10=30. So the problem will now be 4/50 + 30/50 = 34/50, and 34/50 silified is 17/25.

how many 4 digit numbers n have the property that the 3 digit number obtained by removing the leftmost digit is one ninth of n

Tom [10]

Answer:

Step-by-step explanation:

We want to find the number 4-digit of positive integers n such that removing the thousands digit divides the number by 9.

Let the thousands digit be 'd'. Then we want to find the integer solutions to ...

n -1000d = n/9

n -n/9 = 1000d . . . . . . add 1000d -n/9

8n = 9000d . . . . . . . . multiply by 9

n = 1125d . . . . . . . . . divide by 8

The values of d that will give a suitable 4-digit value of n are 1 through 7.

When d=8, n is 9000. Removing the 9 gives 0, not 1000.

When d=9, n is 10125, not a 4-digit number.

There are 7 4-digit numbers such that removing the thousands digit gives 1/9 of the number.

A projector was sold after allowing 10% discount on the marked price and levying 13% VAT .If the selling price of the projector

Tom [10]

The marked price of the projector is $50,000.

<h3>What is the marked price?</h3>

The price of the projector after the discount can be represented with:

(100 - 10%)x - 90%x = 0.90x

Where x is the marked price

The price of the projector after the VAT is : (1.13) x 0.90x = 1.02x

Difference in price = 1.02x - 0.90x = 5850

0.12x = 5850

x = 5850 / 0.12

x = $50,000

Solve in degrees. 0 < θ < 360<br> 1. tan θ = 3.5134

Temka [501]

Answer:

Therefore,

$\theta=74.11\°\ or\ \theta=254.11\°$

Step-by-step explanation:

Given:

0° < θ < 360°

tan θ = 3.5134

To Find:

θ in degrees = ?

Solution:

0° < θ < 360° .............Given

Means ' θ ' is between 0° and 360°

$\tan \theta=3.5134$ .............Given

Therefore,

$\theta=\tan^{-1} (3.5134)$

Also,

$\tan (180+\theta)=\tan \theta$

So ' θ ' will have Two values for tan θ =3.5134

$\therefore \theta=74.11\°\ or\ \theta=180+74.11=254.11\°$

Therefore,

$\theta=74.11\°\ or\ \theta=254.11\°$
