Answer: 25%
Step-by-step explanation:
first you would take 500/20
Answer:
4.2 x 10⁶
Step-by-step explanation:
The problem says that there are 6x 10² times as many red blood cells as white blood cells. This means that you will need to multiply the given number of white blood cells, which is 7 x 10³ by 6x 10².
To do this, first you multiply the coefficients:
7 x 6 = 42
Next you combine the exponents of the 10s, because their bases are the same, we just add the exponents when you multiply them and copy the base:
10² x 10³ = 10⁵
So the result would be:
42 x 10⁵
However the following the form of scientific notation, you need to move the decimal one more time so that means you add one more to the exponent of 10.
4.2 x 10⁶
Answer:
650
Step-by-step explanation:
so the way I did this was by adding how much he works per week which is 35 per week. so he works 70 hours in 2 weeks. he earns 10 dollars per hour. so 10 times 70 you get 700 but he spends 50. so 700 minus 50. you get 650. he has 650 dollars left.
Answer:
x=77
Step-by-step explanation:
Since both triangles are congruent, the angles will also be equal. Hence, x=77 degrees.
