Answer:
Hence, 0.0000087 can be expressed as 
.
Step-by-step explanation:
- Given 0.00000871
- Move the decimal point so that the factor is greater than or equal to 1 but less than 10 .
- Then count n and write no. as product with a power of 10 .
Step 1 of 1
Consider 0.00000871,
8.71
Decimal has moved 6 places to right.
The power will be negative as the original no. is less than 1 .
Answer: 4 buffalos and 20 chickens (i think)
Step-by-step explanation:
2x+4y= 8
Ducks have 2 legs and buffalos have 4.
x= ducks y=buffalos
2(24-y)+4y=24
48-2y+4y=40
2y=8
y=4
4 buffalos
x+y=24
x=24-y
x=24-4
x=20
20 ducks
Answer:
6x<100-15
6x<85
x<85/6
x<14.17
Step-by-step explanation:
Answer:
Step-by-step explanation:
substitute and solve:
100 = bh
100 = b(2b)
100 = 2b²
50 = b²
b = √50
b = √(25 * 2)
b = 5√2
solve for h:
h = 2b
h = 2(5√2)
h = 10√2
if you are told to round to 1 DP :
b ≈ 7.1 m
h ≈ 14.1 m
