Answer:

The fraction that represents the decimal 0.12 is 3/25

Step-by-step explanation:

step 1: find the place value of the last digit in 0.12

Since they are 2 digits in 0.12 the place value of last digit is the 100 th, therefore 0.12 is the same as 12/100

step 2: simplify 12/100 by dividing both the denominator and numerator by 4

that is 12 divide by 4 = 3 and 100 divide by 4 =25

therefore the fraction = 3/25

Nikolay [14]

The system of inequalities models correctly the number of cookies is c + b ≥ 125 and 8c + 12b ≤ 2000

Let c represent the number of cookies and let b represent the number of brownies.

Since Genie want to make more than 125 cookies and brownies altogether, hence this is given by:

c + b ≥ 125 (1)

Also, Genie has a total of 2,000 grams of flour, hence:

8c + 12b ≤ 2000 (2)

Therefore the system of inequalities models correctly the number of cookies is c + b ≥ 125 and 8c + 12b ≤ 2000

Answer:

7 fiction and 23 non- fiction

Step-by-step explanation:

The number of non-fiction read was 5 less than 4 times the number of fiction books.

Assume fiction books are x.

An equation representing this would be:

x + (4x - 5) = 30

5x - 5 = 30

5x = 30 + 5

x = 35 / 5

x = 7 fiction books

Non-fiction books:

= 4x - 5

= 4 * 7 - 5

= 23 non - fiction books

RSM wants to send four of its 18 Math Challenge teachers to a conference. How many combinations of four teachers include exactly

tatiyna

Answer:

1120 combinations of four teachers include exactly one of either Mrs. Vera or Mr. Jan.

Step-by-step explanation:

The order in which the teachers are chosen is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

1 from a set of 2(Either Mrs. Vera or Mr. Jan).

3 from a set of 18 - 2 = 16. So

$C_{2,1}C_{16,3} = \frac{2!}{1!1!} \times \frac{16!}{3!13!} = 1120$

1120 combinations of four teachers include exactly one of either Mrs. Vera or Mr. Jan.

Answer:

C and D

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

= 2πr × $\frac{60}{360}$

= 2π × 10 × $\frac{1}{6}$ = $\frac{20\pi }{6}$ = $\frac{10\pi }{3}$ cm → C

-----------------------------------------------------

The area (A) of a sector is calculated as

A = area of circle × fraction of circle

= πr² × $\frac{60}{360}$

= π × 10² × $\frac{1}{6}$ = $\frac{100\pi }{6}$ = $\frac{50\pi }{3}$ cm² → D
