Samantha is making flower arrangements. She has 32 roses and 96 daisies. If she wants to make all the arrangements identical and
-Dominant- [34]

Answer:

3 daisies.

Step-by-step explanation:

Given that,

Samantha has 32 roses and 96 daisies.

She wants to make all the arrangements identical and have no flowers left over. We need to find the no of daisies in each flower arrangement.

For this, we need to first find the HCF of 32 and 96.

The factors of 32 are: 1, 2, 4, 8, 16, 32

The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96

HCF = 32

No of daisies = 96/32 = 3

Hence, there are 3 daisies in each flower arrangement.

Can you help me solve
Sloan [31]
The angle measures tell you the triangles are similar, so corresponding sides will have the same ratio.
  GX/BX = UH/NH
  GX = BX·UH/NH
  GX = 7·18/(3√11)
  GX = (42/11)√11

  GB/BX = UN/NH
  GB = BX·UN/NH
  GB = 7·15/(3√11)
  GB = (35/11)√11

Let f(x)= log x
marshall27 [118]

Answer:

The average rate of change of f(x) from 2-3 is 0.176

Step-by-step explanation:

Rate of change= change in y / change in x

                        = log 3 - log 2 / 3-2

                        = 0.477-0.301 / 1

                        = 0.176

What is an equation for the linear function whose graph contains the points (9, 7) and (4, −8) ?
aalyn [17]
Y=mx+b where m=slope which is change in y divided by change in x                 m=(-8-7)/(4-9)=-15/-5=3 so we have                                                                 y=3x+b now we can use either point, I'll use (9,7), to solve for b or the y-intercept...                                                                                                         7=3(9)+b                                                                                                           7=27+b                                                                                                         b=-20so our line is:                                                                                              y=3x-20

How many 12 x 12 pavers for 600 square feet?
34kurt
First, we calculate the area of one paver. This is:
12 x 12 = 144 square feet
Now, the number of pavers required may be determined by dividing the total surface area to be covered by the surface area of one paver, as:
number of pavers = 600 / 144
Number of pavers = 4.2

Because 0.2 pavers can not be obtained, 5 pavers are needed to completely cover 600 square feet.
