Answer:
1.17%
Step-by-step explanation:
23,000 divide by 19,700
15/2 if you are binging it to simplest form
2,376 square feet
**
Add the areas of all the sides of the shape.
A triangle's area: 1/2bh
The two triangles' area=24*9=216
The bottom side: 40*24=960
The two other sides: 30*40=1200
Add everything: 216+960+1200=2376
<span>answer:28/52 chance aka 54% chance
Work:
Prob(ace or black card)= Prob(ace) + Prob(black card) - P(ace and black card)
</span><span>=4/52 + 26/52 -2/52
=28/52</span>
