I’m not sure how your class works, but usually if they are circled it means you only have to do the circled ones. GCF always stands for greatest common factor

total of 5 flowers.

50 flowers

Tulips ratio to total flowers is 3 to 5

50 * 3/5 = 150/5 = 30

Roses ratio to total flowers is 2 to 5

50 * 2/5 = 100/5 = 20

Tulips to roses ratio on 50 flowers : 30 to 20.

Sin 0 = 7/25 and cos 0 = -24/25. Find tan 0

9966 [12]

Answer:

$tan \theta = - \frac{7}{24}$

Step-by-step explanation:

$sin \theta = \frac{7}{25} \ , \ cos\theta = \frac{-24}{25}\\\\tan \theta = \frac{sin\theta}{cos\theta}$

$=\frac{\frac{7}{25}}{\frac{-24}{25}} \\\\=\frac{7}{25} \times \frac{25}{-24}\\\\= - \frac{7}{24}$

3. The dance club at school has 22 members. The dance coach wants to send four members to a special training on

diamong [38]

Answer:

a) a combination

b) The probability = 1 ÷ [ Number of ways to select the four dancers ]

Step-by-step explanation:

a) Here it is only required to calculate the number of ways to select the four dancers and the order of the dancers is not required i.e not important for us.

Hence, we will use a combination to select 4 out of 22 dancers

i.e ²²C₄

b) Since the dancers selected are 4 predetermined individuals

therefore,

number of ways to select selecting dancers Laura, Matthew, Lakiesha, and Santos will be '1'

Hence,

The probability = 1 ÷ [ Number of ways to select the four dancers ]

= 1 ÷ ²²C₄

I will give the brainiest

weeeeeb [17]

Answers:

36 individual black socks

38 individual white socks

Check: 36+38 = 74 total individual socks

====================================================

Work Shown:

b = number of pairs of black socks

w = number of pairs of white socks

w = b+1 since he has 1 more pair of white socks compared to black socks

2b = number of individual black socks

2w = number of individual white socks

2b+2w = total number of individual socks

2b+2w = 74

2b+2(b+1) = 74 .... plug in w = b+1

2b+2b+2 = 74 ... distribute

4b+2 = 74

4b = 74-2 .... subtracting 2 from both sides

4b = 72

b = 72/4 ... dividing both sides by 4

b = 18 is the number of pairs of black socks he has

2b = 2*18 = 36 is the number of individual black socks he has

w = b+1 = 18+1 = 19 is the number of pairs of white socks he has

2w = 2*19 = 38 is the number of individual white socks he has

2b+2w = 36+38 = 74 individual socks overall
