Answer:

Rate in simplest form = 52/3 inches in one second.

Step-by-step explanation:

We have given,

A rate is given in the form as 260 inches in 15 seconds

That means, if we need to find equivalent rate for 1 second in terms of inches then,

We can write:

15 seconds ---------> 260 inches

1 second -----------> 260/15 inches

or 1 second --------> 52/3 inches

so we can write the rate in simplest form as:

Rate = 52/3 inches in one second.

Answer:

$\frac{2}{4} inch$

Step-by-step explanation:

Step 1

List the length of the wingspan of the five butterflies

$\frac{1}{4}, \frac{1}{4}, 1, \frac{2}{4}, \frac{3}{4}$

Step 2:

The two butterflies with the shortest wingspan has a wing length of $\frac{1}{4}$ inches each.

Step 3:

Total length of the wingspan of the two butterflies with the shortest wingspan

= $=\frac{1}{4} +\frac{1}{4} \\
 = \frac{2}{4}$

Final answer:

= $\frac{2}{4} inch$

Day 4: As a landscaper, one of your clients wants a rectangular garden in which the length is five feet

liberstina [14]

Answer:

The Area of Rectangular Garden is 1044 feet²

Step-by-step explanation:

According to question

The perimeter of the garden = 82 ft

Let the length be L ft

The width be W ft

Now as per question

L = 5 + ( 2× W )

∵ Perimeter of Rectangle = 2 × ( Length + Width )

Or , Perimeter of Rectangle = 2 × ( L+ W )

Or, 82 = 2 × ( L+ W )

Or, 82 = 2 × [ 5 + ( 2 ×W ) + W ) ]

Or, 82 = 2 × ( 5 +3W )

Or, 41 = 5 + 3W

Or, 41 - 5 = 3W

So, 3W= 36

∴ W = $\frac{36}{3}$ = 12 feet

I.e Width = 12 feet

And L = 5 + ( 2× W )

Or, Length = 5 + 24 = 29 feet

Now The Area of Rectangle = Length × width

So, The Area of Rectangle = 29 ft × 36 ft

The Area of Rectangle is 1044 feet²

Hence The Area of Rectangular Garden is 1044 feet² Answer

Nataliya [291]

Answer:

(27.3692 ; 44.6308)

Step-by-step explanation:

Mean, xbar = 36

Standard deviation, s = 11

Sample size, n = 12

Tcritical at 0.2, df = 12 - 1 = 11 ; Tcritical = 2.718

Confidence interval :

Xbar ± Margin of error

Margin of Error = Tcritical * s/sqrt(n)

Margin of Error = 2.718 * 11/sqrt(12) = 8.6308

Confidence interval :

Lower boundary : 36 - 8.6308 = 27.3692

Upper boundary : 36 + 8.6308 = 44.6308

(27.3692 ; 44.6308)

We can solve using proportions.

$\frac{6 \: bags}{25.50 \: dollars} = \frac{5 \: bags}{x} \\ \\ \frac{127.5}{6} = \frac{6x}{6} \\ \\ 21.25 = x \\ 21.25 \: dollars = x$
