9)Lareina understands factors. Sometimes she has trouble finding all of the factors of a number. What advice would u give Larein a to help her find all of the factors of a number? Demonstrate by finding all of the factors of 110. 10) a. Find two numbers that have 2,3,and 5 as factors. What other factors do the two numbers have in common?
b. Find three numbers that have 2,4,and 8 as factors. What do these numbers have in common?
1 answer:
9. It is a very good idea to divide by the smallest numbers. First divide by 2 as many times as you can, then by 3, and so on: 110=2*55 (2 is an obvious factor, since the number ends with 0) 2*55=2*5*11 (5 is an obvious factor since the number ends with 5) 10.a to find a number with factors 2, 3, 5, just multiply these numbers with any other number you want. number 1: 2*3*5*4=120 number 2: 2*3*5*9=270 The greatest common factor of these 2 numbers is 2*3*5 any combination of these numbers is a common factor to number 1 and number 2, so these numbers have in common the factors: 2*3=6, 3*5=15, 2*5=10, 2*3*5=30 that is {6, 10, 15, 30} b. a number with 8 as a factor, has also 2 and 4 as factors. so a number with factors 2, 4 and 8 can be found by simply multiplying 8 by any number. number 1: 8*5=40 number 2: 8*11=88 number 3: 8*500=4,000 these numbers have in common that they all are multiples of 8 (their greatest common divisor is 8)

Answer:
No
Step-by-step explanation:
For the adults:
$12 times the 14 adults which is: $168
Then for the kids:
$5 times the 9 kids which is: $45
Add next:
$168 plus the $45 equals $213
A(14)+b(5)=c
Answer:
73 and -23 hope this helped hon :)
Step-by-step explanation:
y=-8x+9
plug in -8
y=-8(-8)+9
y=64+9
y=73
y=-8x+9
plug in 4
y=-8(4)+9
y=-32+9
y=-23
Answer:
Step-by-step explanation:
<u>It is assumed the angles A and C are congruent:</u>
3x + 40 = x + 50 3x - x = 50 - 40 2x = 10 x = 5 m∠A = 3*5 + 40 = 55°
