Answer:

4.2 × 10⁻⁵

Step-by-step explanation:

The decimal point must be after the first non-zero digit.

⇒ 4.2

Multiply 4.2 by a number that results in 0.000042. That number is 0.00001 or 10⁻⁵.

⇒ 4.2 × 10⁻⁵

Answer:

Answer 1: 0.8

Answer 2: 0.238

Answer 3: R = \frac{18.40}{2.3} = \frac{18.4 \times 10 }{2.3 \times 10} = \frac{184}{23} = 8 dollars per hour.

Step-by-step explanation:

Answer 1:  

We have to evaluate 4.8 ÷ x for the value of x = 6

Now, \frac{4.8}{6} = \frac{48}{6 \times 10} = \frac{8}{10} = 0.8 (Answer)

Answer 2:  

We have to find the quotient of 0.9 ÷ 3.78

Now, \frac{0.9}{3.78} = \frac{900}{378} \times \frac{100}{1000} = 2.38 \timers \frac{1}{10} = 0.238 (Answer)

Answer 3:

A. Emma earned $18.40 by babysitting. she worked 2.3 hours.  

Now, the rate of payment to Emma per hour for babysitting is R = \frac{18.40}{2.3} ............. (1) dollars per hour.

B. While solving this division problem we must change the divisor a whole number.

C. Hence, to change the divisor into a whole number we must multiply the numerator and the denominator by 10.

Hence, R = \frac{18.40}{2.3} = \frac{18.4 \times 10 }{2.3 \times 10} = \frac{184}{23} = 8 dollars per hour. (Answer)

The perimeter of a rectangle is 96 inches. If the
WINSTONCH [101]

Answer:

The width of the rectangle=21 inches

Step-by-step explanation:

<em>Step 1: Determine the dimensions of the rectangle</em>

Width=w

Length=l

But;

triple width=length+36

3×w=l+36

3 w=l+36

The length can be expressed as;

l=3 w-36

width=w

length=3 w-36

<em>Step 2: Determine the perimeter of the rectangle</em>

P=2(L+W)

where;

P=perimeter

L=length

W=width

In our case;

P=96 inches

W=w

L=3 w-36

replacing;

2(w+3 w-36)=96

2(4 w-36)=96

8 w-72=96

8 w=96+72=168

8 w=168

w=168/8=21

The width of the rectangle=21 inches
