Answer:

a) 2800-( 28000 * 12,5%) * X

b) 7000$

Step-by-step explanation:

X = amount of year

2800-( 28000 * 12,5%) * X = value of a car after X year

Your mean like that :))

The value of the car decreases per year :

28000 * 12,5% = 3500$ per year

The value of the car after 6 years :

28000 - 3500 * 6 = 7000$

Done :))

X and y are both bigger than 30. x and y have HCF 21 and LCM 1617. Find x and y.

Sunny_sXe [5.5K]

The values of x and y are 99 and 343

The HCF of numbers is the highest common factors of the numbers

The LCM of numbers is the lowest common multiple of the numbers

The HCF and the LCM are given as:

$HCF = 21$

$LCM = 1617$

Multiply the HCF and the LCM

$HCF \times LCM = 21 \times 1617$

$HCF \times LCM = 33957$

The product of the numbers x and y equals the product of the HCF and the LCM.

So, we have:

$x \times y = 33957$

<h3>Prime Factors</h3>

Express 33957 as a prime factor

$x \times y = 3^2 \times 7^3 \times 11$

Rewrite the equation as

$x \times y = 99 \times 7^3$

$x \times y = 99 \times 343$

By comparison:

$x = 99$

$y= 343$

Hence, the values of x and y are 99 and 343

In a recent year, 22 percent of email users said they spend less time using email because of spam. what fraction of email users

Alchen [17]

Remember, percent is always out of 100. If you have 22%, you have 22 people per every 100 people, or, 22/100.

22/100 is the incomplete answer because it needs to be simplified. If you divide both numbers by two you get 11/50 which is the lowest fraction you can have because 11 is a prime number.

Ok, so I'm pretty sure this one is 11.5 I just wanted to make sure with u guys! :)

Furkat [3]

Answer:

C: 23 cm

Step-by-step explanation:

This is the answer because:

1) Area of trapezoid is: (base1 + base2)/2 x height

2) In this case, it is 14 + 8 which is 22. 22/2 is 11.

3) Now we have to do 253/11 which is 23 cm.

Hope this helps! :D
