There are a total of 68 cars in the parking lot (sum of all values on the table).
Selecting blue OR a chevy, means all blue and all chevies are valid choices...there are 7+9+8+7+5 (blue cars and chevy cars) = 36:
36/68 = 9/17
Selecting blue AND a chevy - There are 8 blue chevies:
<span>8/68= </span>2/17
GIVEN that the car is blue means we're <em>only selecting from </em>the 7+9+8 = 24 blue cars on the lot which are chevies...and there are 8 blue chevies:
8/24 = 1/3
Answer:
- 24 cm²
- 6400 -1600π ≈ 1373.45 square units
Step-by-step explanation:
1. You can look at this several ways.
It can be considered to be a stack of 1+2+3 = 6 squares that are 2 cm on a side, so have a total area of 6 × (2 cm)² = 24 cm².
You can lop off one of the squares sticking out and put it into the empty corner to form a 6 cm by 4 cm rectangle with an area of (6 cm)(4 cm) = 24 cm².
You can consider it to be a 6 cm square with 3 squares cut out of it that are 2 cm on a side: (6 cm)² -3(2 cm)² = (36 -12) cm² = 24 cm².

2. The shaded area is the difference in areas of a square 80 units on a side and a circle of 40 units radius. If we let d represent the side dimension of the square, then the area formulas are ...
Square area = d²
Circle area = π(d/2)²
So the difference area is ...
shaded area = d² -(π/4)d² = d²(1 -π/4)
For d=80, the shaded area is ...
shaded area = 80²(1 -π/4) = 6400 -1600π ≈ 1373.45 square units
Answer:
a
Step-by-step explanation:
I believed it is "401"
1-9 = 9 digits
10-99 = 90 which is 180
100-200 = 100 which is 300 digits
9+180= 189
1392-189= 1203
1200÷300=400 which 1200 digits
401 is the 1392 number scanned
