<span>10.1, 20.1 ,
30.1 are the decimal where the value of digit 1/10 had existed.</span>
<span>“Decimal”
comes from the Latin root decem, which simply means “ten.” The
number system we use is called the decimal
number system, because the place value units go in tens: you have ones,
tens, hundreds, thousands, and so on, each unit being 10 times the previous
one.</span>
In common language, the word
“decimal number” has come to mean numbers which have digits after the decimal
point, such as 5.8 or 9.302. But any number within the decimal number system
could be designate a decimal number, involve whole numbers such as 12 or 381.
<span>A Decimal Number (<span>based on the number 10</span>) contains a Decimal Point.</span>
<span>Here is the number "forty-five and six-tenths" written as
a decimal number:</span>
The decimal point goes between Ones and
Tenths.
45.6 has 4 Tens, 5 Ones and 6
Tenths, like this:<span>40+5+6/10</span>
Answer:
Step-by-step explanation:
30t - 5t² = 10
5t² - 30t + 10 = 0
t = [30 ± √(30² - 4 ⋅ 5 ⋅ 10)] / [2 ⋅ 5]
= [30 ± √700] / 10
= [30 ± 10√7] / 10
= 3 ± √7
≈ 0.35 seconds and 5.65 seconds
Answer:7
Step-by-step explanation:
There is a gap of 7 in between each number
Answer:
The equation of the boundary of the region is (x+2)² + (y-1)² = 25
Step-by-step explanation:
The satellite is positioned at (-2,1) and can sense the presence within 5 miles of its position.
The boundary of the region is a circle with center (-2,1) and radius 5.
The equation of the circle with center (h,k) and radius r is given by
(x-h)²+(y-k)²=r²
The equation of the circle with center (-2,1) and radius 5 is given by
(x+2)²+(y-1)²=5²=25
(x+2)² + (y-1)² = 25 is the required equation of the boundary of the region.
