Answers:

The lengths of sides PQ and RS are <u> 13 </u>
The lengths of sides QR and SP are <u> </u><u>20 </u>

This is a 13 by 20 rectangle.

============================================================

Explanation:

Refer to the drawing below.

Let x be the length of side SP. Since we're dealing with a rectangle, the opposite side is the same length. Side QR is also x units long.

We're told that RS = SP - 7 which is the same as saying RS = x-7

We also know that PQ = x-7 as well because PQ is opposite side RS.

In short, we have these four sides in terms of x

PQ = x-7
QR = x
RS = x-7
SP = x

as shown in the drawing. The four sides add up to the perimeter of 66.

PQ+QR+RS+SP = perimeter

PQ+QR+RS+SP = 66

(x-7)+x+(x-7)+x = 66

4x-14 = 66

4x = 66+14

4x = 80

x = 80/4

x = 20

Use this x value to find the unknown side lengths.

PQ = x-7 = 20-7 = 13
QR = x = 20
RS = x-7 = 20-7 = 13
SP = x = 20

In short, this is a 13 by 20 rectangle.

-----------------

Check:

perimeter = side1+side2+side3+side4

perimeter = PQ+QR+RS+SP

perimeter = 13+20+13+20

perimeter = 33+33

perimeter = 66

The answer is confirmed.

Find the integers that correspond to the given description. fewer than 28 people Select the correct choice below and fill in the

Naily [24]

Answer:

The interger is up to 27

Step-by-step explanation:

let X represent the number of people.

For fewer than 28 people, we have;

(X ∠28)

Meaning,

(X ∠28) = (X ≤27)

(X = 1) + (X = 2) + (X = 3) ............+ (X = 27)

1 +1 + 1 +...............(27 times)

Therefore, the interger is up to 27

The function D =25+0.3 X represents the daily dental charge D in dollars for X miles driven

Lady_Fox [76]

Answer:

See Explanation

Step-by-step explanation:

Given

$D = 25 + 0.3X$

The question has missing details; as what's required is not stated.

However, since it is a linear equation, possible questions could be

1. Determine the slope

2. Determine the D-intercept

3. Calculate the amount in dollars for (say) 5 miles

An equation is represented as:

$D = b + mx$

Where

$b = D\ intercept$

$m = slope$

By comparing: $D = 25 + 0.3X$ to $D = b + mx$

$b = 25$ and $m = 0.3$

This means that the slope is 0.3 and the d intercept is 25

To get the amount for 5 miles, we substitute 5 for x in $D = 25 + 0.3X$

$D = 25 + 0.3 * 5$

$D = 25 + 1.5$

$D = 26.5$

<em>The cost of 5 miles is $26</em>

Make use of the above explanation to solve the question

Devante buys 1/1/4 pounds of cashews 7 ounces of almonds and 3/4 pounds of pecans how much do the nuts weight in

liberstina [14]

Answer: $39\ \text{Ounces}$

Step-by-step explanation:

Given

The amount of cashews is $1\frac{1}{4}\ \text{Pounds}$

Amount of almonds $7\ \text{ounces}$

The amount of pecans is $\frac{3}{4}\ \text{Pounds}$

We know, $1\ \text{Pound}=16\ \text{Ounces}$

Converting pounds to ounces and adding them

$\Rightarrow 1\dfrac{1}{4}\times 16+7+\dfrac{3}{4}\times 16\\\\\Rightarrow \dfrac{5}{4}\times 16+7+3\times 4\\\\\Rightarrow 20+7+12=39\ \text{ounces}\ or\ \dfrac{39}{16}\ \text{Pounds}$

Thus, the nuts weigh $39\ \text{Ounces}$
