what is 4.5x10^-6 in standard notation?

Answers

Answer 1
It would be 0.0000045 because it is a - you go left but if it was positive you would go right and you are moving the decimal
Answer 2

The number 4.5x10⁻⁶ can be expressed in standard notation as decimal 0.0000045.

In scientific notation, numbers are expressed as a decimal number between 1 and 10 multiplied by a power of 10. In this case, 4.5 is the decimal number and 10⁻⁶ represents the power of 10.

To convert this to standard notation, we move the decimal point six places to the left to match the negative exponent of 10⁻⁶. This gives us:

0.0000045

In standard notation, this number is written as 0.0000045, where the zeros after the decimal point indicate the value of the number in the place of each digit. The last non-zero digit in this case is 5, which is in the sixth decimal place.

Answers

Answer:

see below

Step-by-step explanation:

a.  We want to see when the two snakes will be the same length.

b.   b1 + r1m= b2 + r2m  where b is the initial length and m is the number of months and r is the  growth rate

c.   for the anaconda  5.23 + 1.27 m  where m is the number of months,  and the total length is in meters

The anaconda starts at 5.23 meters and grows 1.27 meters each month for m months

d.  for the python 4.76 + 2.04m   where m is the number of months, l is the length of the python in meters

The python starts at 4.76 meters and grows 2.04 meters each month for m months

e.  5.23 + 1.27 m  = 4.76 + 2.04m   m is the number of months  Each side is the number of meters

Taino went to a professional basketball game. He spent $54.85 for a ticket, $4.99 for a hot dog, and $2.15 for a soda. What is the total amount that he spent? Use mental math to find the sum.

Answers

Answer:

$61.99

Step-by-step explanation:

To find the total, we need to add.

Let's start with the ticket and the soda.

54+2=56

0.85+0.15=1

56+1=57

Next, add the price of the hot dog.

4.99 rounds to 5, so 57+5=62

62-0.01=61.99 (here we subtracted the one cent we originally rounded up)

The price of a ring was increased by 30% to £325. What was the price before the increase?
Please answer asap!!​

Answers

Answer:

227.5

Step-by-step explanation:

Find the number that is increased by 30% to get to 325.  

100-30 = 70.

In other words, what number is 70% of 325.

325 x .70 = 227.5

The original price of the ring was 227.5.

Check your work, 227.5 = 70% of X

227.5  / .70  = 325

Answer:

The cost before the increase is £250.

Step-by-step explanation:

Given that after 30% increases, the cost of the ring is £325 so we can assume that 130% is £325. Now, we have to form an expression in term of x where x represents the original cost :

[tex] \frac{130}{100} \times x = 325[/tex]

Next, we have to solve it :

[tex]x = 325 \div \frac{130}{100} [/tex]

[tex]x = 325 \times \frac{100}{130} [/tex]

[tex]x = 250[/tex]
