Someone quickly hell
Elza [17]

Answer:

£3,780

Step-by-step explanation:

Total rows = 19 rows

Seats per row = 28 seats

Cost of tickets per seats = £8.75

Total number of seats at the concert = Total rows × seats per row

= 19 rows × 28 seats

= 532 seats

The tickets for 100 seats have not been sold

Total number of tickets = sold tickets + unsold tickets

532 = sold tickets + 100

532 - 100 = sold tickets

432 = sold tickets

Sold tickets = 432 tickets

Total cost estimate of sold tickets = sold tickets × cost of tickets per seats

= 432 × £8.75

= £3,780

Use technology or a z-score table to answer the question.
Romashka-Z-Leto [24]
121 of the green beans will be shorter than 13 centimeters.

First, we need to evaluate the expression below to find the z-score.
(13 - 11.2) / 2.1. = 0.86

The matching percent for this z-score is 0.8051.

Multiplying 0.8051 by 150 gives us about 121 green beans.

Sav [38]
There's a catch here, and I don't really want to go into full detail.  Because of
this catch, I think it would be unusually tough to write a simple equation for this
situation. If you wouldn't mind, let's just list it instead:

<u>After</u> . . <u>water added</u> . . <u>total in pool</u>

7 min . . . 14 gallons . . . 14 gallons
1 more . . 1 gallon . . . . . 15 gallons
7 more . . 14 gallons . . . 29 gallons
1 more . . 1 gallon . . . . . 30 gallons
5 more . . 10 gallons . . . 40 gallons, the pool is full

Add up all the minutes: <u>21 minutes</u>

How many pennies could you have if: When you break the pennies into groups of 2, you have 1 penny left over, AND when you break
dsp73

Answer:

31 pennies

Step-by-step explanation:

Given that:

Breaking the number of pennies into 2 groups, there is 1 penny left over.

Breaking the pennies into 3 groups, there is 1 penny left over.

Breaking the pennies into 5 groups, there is 1 penny left over.

Breaking the pennies into groups implies that the same number of pennies are in each group for each case. Since there is no restriction to the number of pennies in the groups for all cases, then the total number of pennies would be 31.

So that;

31 = 15 + 15 + 1 =  2 groups + 1

31 = 10 + 10 + 10 + 1 = 3 groups + 1

31 = 6 + 6 + 6 + 6 + 6 + 1 = 5 groups + 1

There are 31 pennies.
