80% of the species are insects.
4/5 x 100, comes out to 80.
Answer:
210/240 simplified is 7/8
Step-by-step explanation:
Experimental probability is based on whats already being tested hope this helps!
13x-8≤-32
add 8 to both sides to get 13x≤-24
divide by 13 to get x ≤ -24/13
Answer:
2.389 x 10^5
Step-by-step explanation:
First, write both numbers out. Move the decimal point right however many times the exponent says. For 8.9, we move the decimal right 3 times, and we would move it right 5 times for 2.3.
230000
<u>+ 8900</u>
238900
Now let's convert this to scientific form. The beginning number in scientific form has to be between 1 and 10, so move the decimal point left until you get a number that fits. Here, we will move it 5 times.
2.38900
Because we've moved it left 5 times, we make the exponent 5.
