A jewelry maker will use 24 blue beads and 30 green beads to make necklaces. What are the possible number of necklaces she can make if each necklace has the same number of blue and green beads? How many of each type will be on each necklace?
Answers
Answer:
- 1 necklace: 24 blue, 30 green
- 2 necklaces: 12 blue, 15 green (each)
- 3 necklaces: 8 blue, 10 green (each)
- 6 necklaces: 4 blue, 5 green (each)
Step-by-step explanation:
The greatest common factor of 24 and 30 is 6. The divisors of 6 are 1, 2, 3, and 6. Those are the numbers of identical necklaces that might be made from the beads. The number of beads of each color is found by dividing the total number of beads by the number of necklaces being made.
The possible numbers of necklaces are 1, 2, 3 or 6.
The numbers of (blue, green) beads on each will be (24, 30), (12, 15), (8, 10), or (4, 5), respectively.
_____
The greatest common factor (GCF) is the product of the common prime factors.
24 = 2^3×3
30 = 2×3×5
The prime factors in common are 2 and 3, so the GCF is 2×3 = 6.

Answer:
Y= 3x-7
Step-by-step explanation:
Since the line is parallel , the slope is same i.e. 3 .
now the equation should be y= Mx + b where m is the slope and c is the y-intercept
plugging the value of m=3 and ( 3,2) into the equation
2= 3(3) + c
2= 9+ c
c= -7
hence the equation of the line is y=3x-7

3 = b + 3
b = 3 - 3
b = 0
The correct result would be d. 0.
Subtract 3 on both sides.
Your final answer is d. 0.

4. Bi-weekly mortgage is $455. Monthly phone charges are $34.95. The electric bill last month was $65.88. Groceries cost about $87/week. What is a good estimate of your monthly expenses?
A: $643.00
B: $904.00 (my answer)
C: $1,098.00
D: $1,359.00

2. If the payment is bi-weekly, and there are 4 weeks in a month, you only have to multiply by 2, because "bi-weekly" means every 2 weeks, which means the payment would come twice a month. So, the answer would be A, Multiply by 2 and then round.
3. Round each of the numbers. 978 becomes 980, 54.89 becomes 55, and 93 becomes 90. We'll assume that there are 4 weeks in a month. Add them all up. 980+55+90+90+90+90 = 1395 So, yes, your answer of D, 1,400.00 is a good estimate.
4. Again, round each of the numbers. 455 can stay the same, 34.95 becomes 35, 65.88 can stay at 65 for the sake of easy math, and 87 gets rounded up to 90.
We'll keep assuming that there are 4 weeks in a month. Now, add them all up. Be sure to remember that the rent is bi-weekly, so it has to be added in twice. 455+455+35+65+90+90+90+90 = 1370. This means that of the choices, D, 1,359.00 is a good estimate of the monthly expenses.

Answer:
Step-by-step explanation:
it is divided into 4 rectangles
first rectangle ( 100 cm ^2)
area = l × b
= 10 × 10 = 100 cm^2
second rectangle ( 60 cm^2)
area = l × b
= 6 × 10 = 60 cm^2
third rectangle ( 20 cm^2)
area = l × b
= 2 × 10 = 20 cm^2
fourth rectangle ( 12 cm^2)
area = l × b
= 2 × 6 = 12 cm^2
so total area of the rectangle = 100 + 60 + 20 + 12 cm^2
= 192 cm^2
