To solve, first let’s define regrouping:<span>
<span>=> Regrouping involves carrying and borrowing during subtraction and addition of the given numbers.

So let us have the non-regrouping decimal number: 
=> 8.4
Next, the other regrouping decimal 
=> 5.7

So now let us show how it becomes 14.1:
  8.4
+5.7
14.1

Starting from the right, 4 + 7 is equal 11, so bring down 1 and carry 1. Now 8+5 = 13, but 13 + carry 1 = 14
<span>Thus, the answer is 14.1</span></span></span>

In a circle with a radius of 6 ft, an arc is intercepted by a central angle of 3π/2 radians.
slamgirl [31]

Answer:

Option 4 - L=9\pi ft.

Step-by-step explanation:

Given : In a circle with a radius of 6 ft, an arc is intercepted by a central angle of 3π/2 radians.

To find : What is the length of the arc?

Solution :

Length of an arc is given by:

L=r\theta

where r is the radius of the circle,  r= 6 ft.

and \theta is the angle in radian, \theta=\frac{3\pi }{2}

Substitute the value given in the formula,

L=r\theta   

L=6\times \frac{3\pi }{2}   

L=3\times3\pi

L=9\pi

Therefore, Option 4 is correct.

The arc of length is L=9\pi ft.

Question 1. Philant sleeps 3/8 of each day. He spends 1/3 of each day at work. What fraction of his day is he not sleeping or wo
Vaselesa [24]
The first question. 7/24

Explanation: first you need to get the fractions to the same denominator so you use lowest common multiples
The lowest common multiple of 8 and 3 is 24 so you times both 3 and 8 by 3 giving you 9/24 and then you times both 1 and 3 by 8 giving you 8/24
When you add these together you get 17/24 so the rest of that would be 7/24

The length of a rectangle is four more than three times the width. If the perimeter of this rectangle is at least 70 square cent
ankoles [38]

Answer:

Step-by-step explanation:

Let L represent the length of the triangle.

Let W represent the width of the triangle.

The length of a rectangle is four more than three times the width. This means that

L = 3W + 4

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

If the perimeter of this rectangle is at least 70 square centimeters, an inequality that can be solved to find the width of the rectangle is

2(L + W) ≥ 70

L + W ≥ 70/2

L + W ≥ 35
