<span>When you write a number in expanded form you show how much each digit values, according its place in the number. For example, in the number 123, 3 values 3, 2 values 2*10 = 20 and 1 values 1*100 = 100, so the expanded form is 100 + 20 + 3. Using this with 84,000, you have the 8 is in the place of ten thousands, 4 is in the place of one thousand, 0 is in the place of hundreeds, 0 is in the place of tens, and 0 is in the place of units. So, the expanded form is: 80,000 + 4000. </span>
Answer:
Step-by-step explanation:
Radius = r = 9 cm
Angle = θ = 200° = 3.5 radians
Now,
Area = 1/2 (9)²(3.5)
Area = 1/2 (81)(3.5)
Area = 282.7 / 2
Area of sector = 141.4 cm²
1/2 + 1/4= 3/4
1/2 + 1/2 = 2/4
2/4+ 1/4= 3/4
Answer:
3/25
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
0.12=0.121
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 10^2 = 100
0.12/1×100/100=12/100
Find the Greatest Common Factor (GCF) of 12 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 4,
12÷4/100÷4 = 3/25
Therefore
0.12 = 3/25
