Answer:
17 cm²
Step-by-step explanation:
First I cut this figure into 2 rectangles. One big and small one. (the big one is on top of the small rectangle).
For the big rectangle, I multiplied its length by its width.
The area of the big rectangle: 3cm * 5cm = 15cm²
For the smaller rectangle, I also multiplied its length and width.
The area of the small rectangle: 1cm * 2 cm = 2cm²
Add up its areas: 15+2
To get 17cm² as your final answer

ignore this I need more letters lol
Answer:
1/4h
Step-by-step explanation:
If the time for the car trip is x, then given that a car trip is 1/2h shorter than a bus trip, it means that adding 1/2h to the time for a car trip gives the time for the bus trip.
Hence, the time for the bus trip
= (1/2 + x)h
since the bus trip is 3/4h, it means that
1/2 + x = 3/4
collecting like terms,
x = 3/4 - 1/2
= 3/4 - 2/4
= 1/4
Hence the car trip is 1/4h.
Answer:
a. 5/32
b. 5/28
Step-by-step explanation:
a. Probabilities in First Pick:
Mystery: 5/8
Science: 2/8
Biography: 1/8
Probabilities in Second Pick: Since books are replaced after the first pick, the probabilities will stay the same:
Mystery: 5/8
Science: 2/8
Biography: 1/8
Hence combined probability = 5/8 * 2/8 = 10/64 = 5/32
b. Probabilities in First Pick:
Mystery: 5/8
Science: 2/8
Biography: 1/8
Probabilities in Second Pick: Probabilities will change since books are not being replaced after the first pick
Mystery: 4/7 <em>(Since mystery book is in the first pick, only 4 books will remain)</em>
Science: 2/7
Biography: 1/7
Hence combined probability = 5/8 * 2/7 = 10/56 = 5/28
