Answer:

scale factor = 1/2

Step-by-step explanation:

for AC: 4 + 4 = 8

8 is the AC of the red triangle

4 is the AC of the blue triangle

to get from 8 to 4, we divide by 2 or multiply by 1/2 (they mean the same thing)

10 is the CB of the red triangle

5 is the CB of the blue triangle

to get from 10 to 5, we divide by 2 or multiply by 1/2

Help please i am stuck on what to do
nikklg [1K]

Answer:

These are confusing Beth , b/c you have to remember that they will add to 100%

Step-by-step explanation:

so

green = 3*  yellow

100% = green + yellow + 35% + 25%

100% = 3* yellow + yellow +60%

40% = 4* yellow

10% = yellow

30% = green

there are 14 purples in the bag , which is 35% of total

14/.35 = 40

there are a total of 40 pins

so

4    are yellow  (10% of 40  or 40* 0.1)

12 are green    (30% of 40  or 40*0.3)

14  are purple  (35% of 40 or 40*0.35)

10  are grey  (25% of 40  or 40*0.25 )

Leila says that 75% of a number will always be greater than 50% of any other number. Complete one inequality to support Leilas c
Greeley [361]
If a number is positive, Leila's theory that 75% of a number will always be greater than 50% of another number is <em>true</em>;<em> </em>however, if both numbers are negative, or if the number of which she finds 50% is much greater than the number of which she finds 75%, Leila's theory could be incorrect.

This inequality shows that Leila is correct: 100(0.75) \geq 50(0.50) (which simplifies to 75 \geq 25)

This inequality shows that Leila is incorrect: 50(0.75) \geq 100(0.50) (which simplifies to 37.5 \geq 50)

Hope this helps!
