Answer:

Some quadrilaterals have two pairs of parallel sides
All trapezoids are four-sided polygons

Step-by-step explanation:

It wouldnt be the first one because all rectangles have two pairs of parallel sides

It wouldn't be the second one because no rhombuses have right angles

<h2><u>Solution 1</u> :</h2>

Cost of $1\frac{1}{3}$ pounds of gummy bears = $4.40

Cost of 1 pound of gummy bears :

$= 4.40 \div 1 \frac{1}{3}$

$= \frac{440}{100} \div \frac{4}{3}$

$= \frac{440}{100} \times \frac{3}{4}$

$= \frac{1320}{400}$

$= \frac{1320 \div 20}{400 \div 20}$

$= \frac{66}{20}$

$= \frac{66 \div 2}{20 \div 2}$

$= \frac{33}{ 10 }$

$= 3 \frac{3}{10}$

$= \color{plum}\bold{\$3.3}$

Therefore, 1 pound of gummy bears = <u>$3.3</u>

<h2><u>Solution 2</u> : </h2>

Cost of 1 pound of gummy bears = $3.3

Money Daniel has = $1.00

Quantity of gummy bears he can afford :

$= 1 \div 3.3$

$= 1 \div 3 \frac{3}{10}$

$= 1 \div \frac{33}{10}$

$= 1 \times \frac{10}{33}$

$= \frac{10}{33}$

$= 0.30$

Therefore, Daniel will be able to buy <u>0.30 pounds</u> of gummy bears from Jio.

Lisa is 6 centimeters taller than her friend Ian. Ian is 10 centimeters taller than Jim. Every month, their heights increase by

Temka [501]

Lan is 146 centimeters tall now.

<u><em>Explanation</em></u>

Let, Lan's current height is $h$ centimeters

As Lisa is 6 centimeters taller than Lan and Lan is 10 centimeters taller than Jim, so Lisa's current height = $(h+6)$ centimeters and Jim's current height = $(h-10)$ centimeters.

Every month, their heights increase by 2 centimeters.

So, after 5 months.....

Lan's height = $h+(2*5)=(h+10)$ centimeters,

Lisa's height = $(h+6)+(2*5)= (h+16)$ centimeters and

Jim's height = $(h-10)+(2*5)= h$ centimeters

Given that, the sum of Ian's and Jim's heights will be 140 centimeters more than Lisa's height in 5 months. So the equation will be....

$(h+10)+h= (h+16)+140\\ \\ 2h+10=h+156\\ \\ 2h-h=156-10\\ \\ h=146$

So, the current height of Lan is 146 centimeters.
