Answer:

x = positive or negative \sqrt{2 (3x+8)}

Step-by-step explanation:

Because it is impossible to simplify this with rational numbers, it is needed to use the quadratic formula. When doing this, you will find that x = positive or negative \sqrt{2 (3x+8)}. Hope this helps! :)

Which fraction represents the decimal 0.12<br> a) 1/12<br> b) 3/25<br> c) 4/33 <br> d ) 33/4
almond37 [142]

Answer:

The fraction that represents the decimal  0.12  is  3/25

Step-by-step explanation:

step 1: find the  place value  of the last digit in 0.12

Since they are 2 digits in 0.12 the   place  value  of last  digit is  the  100 th, therefore  0.12 is the same as  12/100

step 2: simplify 12/100  by dividing both the denominator and numerator  by 4

that is   <u>1</u><em><u>2 divide by 4   = 3  and 100 divide by 4  =25</u></em>

therefore  the fraction = 3/25

1/2 full

Vcylinderthisone=(1/2)hpir^2
given
h=250
r=100

so

V=(1/2)(250)pi(100)²
V=125pi10000
V=1250000pi
aprox pi=3.141592
V=3926990 cm^3

divide by 1000

Tina is saving to buy a notebook computer. She has two options. The first option is to $400 away initially and save $30 every mo
LuckyWell [14K]

Answer:

Let n represent the number of months after Tina would save the same amount using either option.

400 + 30n = 100 + 50n

400 + 30n − 30n = 100 + 50n − 30n Subtraction Property of Equality

400 = 100 + 20n            Combine like terms.

400 − 100=100 + 20n − 100 Subtraction Property of Equality

300 =20n

300

20

 =  

20n

20

15 months=n

After 15 months, Tina will save the same amount using either option.

400 + 30(15)=100 + 50(15)

400 + 450=100 + 750

850 = 850

After 15 months, Tina will save $850 with either option.
