1. scientific notation and percent. (based on the ideas in objective 1 and objective 4.) 6 points
two percent of sennie's skin cells were burned when she escaped from a fire. if 3.5 x 100 of her skin cells
were burned then, how many skin cells were not burned?

skin cells were not burned.

Step-by-step explanation:

Let be "x" the number of Sennie's skin cells that were not burned when she escaped from the fire.

According the the data given in the exercise, you know that 2% represents of Sennie's skin cells that were burned. This means that the percent of her skin cells that were not burned is:

With this information you can write the following proportion:

Solving for "x", you get:

To express the result in Scientific notation, the decimal point must be after the first digit; then you must  move the decimal point two places to the left:

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
