Answer:

21 cards left to be signed

Step-by-step explanation:

1/3 of 72 is 24

So Harrison signed 24

3/8 of 72 is 27

Sp Alwine signed 27

24+27=51

So 72-51=21

Answer:

21 cards left

Step-by-step explanation:

We know that:

72 - (Harrison + Alwine) = Cards left to sign
Harison = 1/3 x 72
Alwine = 3/8 x 72

Solution:

72 - {(1/3 x 72) + (3/8 x 72)} = Cards left to sign
=> 72 - {24 + 27} = Cards left to sign
=> 72 - {51} = Cards left to sign
=> 72 - 51 = Cards left to sign
=> 21 cards left

Hence, 21 cards are left when Harrison signs 1/3 of the cards and Alwine signs 3/8.

A theatre has the capacity to seat two levels. The circle and the stalls. The ratio in the number of seats in the circle compare

Nady [450]

Answer:

76.19% is the percentage of occupancy on last Friday.

Step-by-step explanation:

The question is incomplete, so the complete question is below:

$A\ theatre\ has\ the\ capacity\ to\ seat\ two\ levels.$ $\ The\ circle\ and\ the\ stalls.\ The\ ratio\ in\ the\ number\ of\ seats\ in\ the\ circle\$ $compared\ to\ the\ number\ of\ seats\ in\ the\ stalls\ is\ 2:5.$ $\ Last\ Friday,\ the\ audience\ occupied\ all\ the\ 528\ seats\ in\ the\ circle$ $\ and\ 2/3\ of\ the\ seats\ in\ the\ stalls.$ $\ What\ is\ the\ percentage\ of\ occupancy\ of\ the\ theatre\ last\ Friday?$

Now, to get the percentage of occupancy of the theatre last Friday.

Let $x$ be all the seats in the stalls.

Total number of seats in the circle occupied by audience last friday = 528.

According to question, 2 : 5 is the ratio in the number of seats in the circle compared to the number of seats in the stalls.

So, 2 is equivalent to 5.

And, 528 is equivalent to $x$ .

Now, to get the number of stalls by using cross multiplication method:

$\frac{2}{5} =\frac{528}{x}$

By cross multiplying we get:

$2x=2640$

Dividing both sides by 2 we get:

$x=1320.$

Total number of seats in the stalls = 1320.

Now, to get the people occupied seats in the stalls on last friday:

$\frac{2}{3} \ of\ 1320\\\\=\frac{2}{3} \times 1320\\\\=880.$

Thus, people occupied 880 seats in the stalls on last friday.

So, the total number of seats in the circle and stalls:

$1320+528\\\\=1848.$

And, the total number of seats people occupied last friday:

$528+880\\\\=1408.$

Now, to get the percentage of occupancy of the theatre last Friday:

$\frac{1408}{1848} \times 100$

$=\frac{140800}{1848} \\\\=76.19\%.$

Therefore, 76.19% the percentage of occupancy on last Friday.

Write a quadratic function f whose only zero is 11

Stells [14]

$\qquad\qquad\huge\underline{{\sf Answer}}$

Here's the solution ~

To write a quadrilatic function, we have to use its roots, like we have to subtract the roots from x and multiply them ~ then we will get our required function !

Since our only root is 11 here, we have to do t double

$\qquad \sf \dashrightarrow \:(x - 11)(x - 11)$
