me this is for test 85 points.

you are lost deep in a forest and haven’t eaten for two days, when you find a patch of toadstools in a clearing between the trees. your mouth waters as you count all 50 toadstools, but you decide that you should check your guidebook to see if they are safe to eat. the guidebook says that in this forest 60% of the toadstools are poisonous, 80% taste terrible, and 56% are both poisonous and taste bad. unfortunately, all of the toadstools kind of look the same, and you are too hungry too even see straight. how many of the toadstools are both non-poisonous and don’t taste bad? • what is the problem asking? what do we know? work out the problem showing each step of your process.

8

Step-by-step explanation:

What is the problem asking : It is asking for the number of toadstools that are both non-poisonous and dont taste bad.

GIVEN : (what we know)

so we have 50 toadstools...

60% are poisonous, 80% taste terrible, 56% are both

this is the equivalent of a venn diagram without the circles :

only poisonousbothonly taste terrible

60% - 56% = 4%                  56%                         80% - 56% = 24%

only poisonous + both + only taste bad + non-poisonous/dont taste bad = 100%

4% + 56% + 24% + x = 100%

84% + x = 100%

x = 100% - 84%

x = 16%so 16% of the toadstools are neither poisonous or dont taste bad.

And we have 50 toadstools16% of which are non-poisonous and dont taste bad

so 16% of 50 = 0.16(50) = 8 <=== non-poisonous / dont taste bad

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
