The members of a singing group agree to buy at least 250 tickets for a concert. The group buys 20 fewer lawn tickets than balcon

sveta [45]

Answer:

Members of Singing group will buy minimum 135 number of balcony tickets.

Step-by-step explanation:

Given:

Minimum of tickets will be bought =250

Let number of lawn tickets be 'l'.

Also Let number of balcony tickets be 'b'

Now given

The group buys 20 fewer lawn tickets than balcony tickets.

Framing in equation form we get;

$l=b-20$

Now The Sum of Number of balcony tickets and Number of lawn tickets should be greater than or equal to Minimum of tickets will be bought by the group.

Framing in equation form we get;

$l+b\geq 250$

Now substituting the value of 'l' in above equation we get;

$(b-20)+b\geq 250\\\\b-20+b\geq 250\\\\2b-20\geq 250\\\\2b\geq 250+20\\\\2b\geq 270\\\\b\geq \frac{270}{2}\\\\b\geq 135$

Now we know the value of b which is 135 we will substitute in equation $l=b-20$ to find the value of l we get;

$l=135-20 = 115$

Hence Members of singing group will buy minimum 135 number of balcony tickets.

If polygon A is a parallelogram, and polygon B is a rectangle, which of the

Daniel [21]

Answer:

The answer is C

Step-by-step explanation:

* Lets talk about some facts in parallelograms and rectangles

- Rectangle is a parallelogram with right angles

- Supplementary angles is two angles their sum is 180°

- The opposite angles in the rectangle are equal and supplementary

- A circle can circumscribe a quadrilateral if the opposite angles of

the quadrilateral are supplementary

- In the parallelograms opposite angles are equal

- The circle can circumscribe a rectangle because its opposite

angles are supplementary

- The circle can't circumscribe a parallelogram because its opposite

angles are not supplementary they are equal

* Lets solve the problem

- Polygon A is a parallelogram

- Polygon B is a rectangle (parallelogram with right angles)

∵ The circle can't circumscribe a parallelogram because its opposite

angles are not supplementary

∴ Polygon A can't circumscribed by a circle

∵ Polygon B is a rectangle its opposite angles are equal the measure

of each one is 90°

∴ Its opposite angles are supplementary

∴ Polygon B can circumscribed by a circle

∵ The rectangle is a parallelogram with right angles

∴ Polygon B represents the only parallelogram that a circle can

circumscribed because opposite angles are supplementary

* The answer is C

Two people apply for loans of the same amount. Due to differences in their credit scores, their payments differ by $72

kati45 [8]

Answer:

$\large \boxed{\text{d) \$2592 }}$

Step-by -step explanation:

The person with the lower credit score pays $72 more each month.

Over 36 mo, they will pay an extra

$\text{Total amount} = \text{36 mo} \times \dfrac{\text{\$72}}{\text{1 mo}} = \textbf{\$2592}\\\\\text{The person with the lower credit score will have paid an extra $\large \boxed{\mathbf{\$2592 }}$}$
