Answer:  B.Start with 45 tiles and separate them into 15 same-sized groups.


Step-by-step explanation:

To evaluate 45 divided by 15 using integer tiles .

Here dividend = 45

Divisor =15

First we need to start with the dividend number, therefore we have to start with 45 tiles .

For the second step we need to separate them into same sized group and the size of the group must be same as the divisor.

Thus, we need to separate 45 tiles into 15 same-sized groups, we will get 3 groups which will be the answer.

Therefore, B is the right option.

In the function f(x)=5(x^2-4+___)+15, what number belongs in the blank to complete the square?
Maurinko [17]

Answer:

2² = 4

Step-by-step explanation:

\text{Use}\\(a-b)^2=a^2-2ab+b^2\\\\f(x)=5(x^2-4x+\underline{\ \ \ })+15\\\\x^2-4x\\\\x^2-2(x)(2)\\\\x^2-2(x)(2)+2^2=x^2-4x+4\\\\\text{Therefore}\\\\f(x)=5(x^2-4x+4)+15=5(x-2)^2+15

Answer:

Q1

<u>The exponential growth model for frogs:</u>

  • F(x) = 100(1.22)ˣ,

F- number of frogs, x- number of years, 1.22 - growth factor

<u>Calculations</u>:

  • F(5) = 100(1.22)⁵ = 270
  • a) F(10) = 100(1.22)¹⁰ = 730
  • b) F(20) = 100(1.22)²⁰ = 5335

Q2

<u>The exponential growth model for bacteria:</u>

  • B(x) = 10(1.8)ˣ

B- number of bacteria, x- number of hours, 1.8 - growth factor

<u>Calculations:</u>

  • a) B(5) = 10(1.8)⁵ = 189
  • b) B(24) = 10(1.8)²⁴ = 13382588
  • c) B(168) = 10(1.8)¹⁶⁸ = 7.68 * 10⁴³

, Hayley sold 20 tickets to the school play for a total of $225 early bird tickets were $10 and regular price tickets were $15 w
Lady_Fox [76]

Answer:

15 early tickets were sold and 5 regular tickets were sold.

Step-by-step explanation:

Let x be the number of early bird tickets sold and y be the number of regular tickets sold.

Total number of tickets sold = 20

Thus, we can write the equation,

x + y = 20

Cost of early bird ticket = $10

Cost of regular tickets = $15

Total cost = $225

Thus, we can write the equation,

225 = 10x + 15y

We solve the equation by elimination method by multiplying first equation by 10 and subtracting.

10x + 15y-(10x+10y) = 225 - 200\\5y = 25\\\Rightarrow y=5\\x + 5 = 20\\\Rightarrow x = 15

Thus, 15 early tickets were sold and 5 regular tickets were sold.
