Answer: 38.31 inches
Step-by-step explanation:
We can think on the round lamp as a circle, then the inches of beads that she will need to go around the lamp is equal to the perimeter of the lamp.
The perimeter of a circle of diameter D, is:
Perimeter = pi*D
where pi = 3.14
In this case, we know that the diameter is 12.2 inches.
Replacing that in the above equation we get that the diameter of the lamp is:
Perimeter = 3.14*12.2 in = 38.31 in
Then Michelle needs 38.31 inches of the beads to go around the lamp.
pls help.........with the help of pic

Step-by-step explanation:
Sam had 225 grams of raisins. After buying another two bags of raisins he then had
175 grams of raisins
He writes this equation where r represents number of bags of raisins to describe how
225r+2=1475
Is he correct? Explain your answer.
How many grams of raisins were in one bag?
Answer: No, he is not correct, the correct equation is:
225 + 2*r = 1475
Solving that, we can find that each bag of raisins has 625 grams of raisins.
Step-by-step explanation:
I suppose that the problem is as follows:
"Sam had 225 grams of raisins. After buying another two bags of raisins he then had 1475 grams of raisins"
Then, if each bag of raisings has r grams of raisings, two bags will have two times that, or:
2*r grams of raisings.
Then if we take what he had at the beginning, and we add these 2*r grams, we should get the 1475 grams that he has at the end:
225 + 2*r = 1475
This is what he should get.
and we can solve it for r, to get:
2*r = 1475 - 225 = 1250
r = 1250/2 = 625
r = 625
This means that each bag of raisins has 625 grams of raisins.
But instead, he got:
225*r + 2 = 1475
In this case, he multiplied his previous amount of raisings by the amount that each bag has, so his equation is wrong.

The drama club is selling gift baskets to raise money for new costumes. During the fall play, they sold a combined 18 regular gift baskets and 19 deluxe gift baskets, earning a total of $1,158. During the spring musical, they sold 15 regular gift baskets and 12 deluxe gift baskets, earning a total of $804. How much are they charging for the different sized gift baskets?
Answer:
The cost of
Regular baskets = x = $20
Deluxe baskets = y = $42
Step-by-step explanation:
The drama club is selling gift baskets to raise money for new costumes.
Let us represent:
The cost of
Regular baskets = x
Deluxe baskets = y
During the fall play, they sold a combined 18 regular gift baskets and 19 deluxe gift baskets, earning a total of $1,158.
Hence:
18x + 19y = 1158....... Equation 1
During the spring musical, they sold 15 regular gift baskets and 12 deluxe gift baskets, earning a total of $804.
15x + 12y = 804...... Equation 2
Combining them two Equations
18x + 19y = 1158....... Equation 1
15x + 12y = 804...... Equation 2
Multiplying Equation 1 by 15 and Equation 2 by 18 to Eliminate x
270x + 285y = 17370..... Equation 3
270x + 216y = 14472...... Equation 4
We Subtract Equation 4 from Equation 3.
69y = 2898
y = 2898/69
y = $42
Solving for x
18x + 19y = 1158....... Equation 1
18x + 19 × 42 = 1158
18x + 798 = 1158
18x = 1158 - 798
18x = 360
x = 360/18
x = $20
Therefore,
The cost of
Regular baskets = x = $20
Deluxe baskets = y = $42

Answer:
how to add and subtract fractions
Step-by-step explanation:
ok so we can start with adding so when you add fractions you can first start out by making the denominators the same number to make it easier so here is an example
7/9 + 3/10 you could make the denomonatiers the same or just do 9x10 and 7x10 + 3x9 and 10x9 and then if you multiply the numbers and added up all the sums you would get to fractions 70/90 + 27/90 so you add them up and science the denominators are the same you just leave them the same number so it would just be 70+27 so you would get 97/90 and because the denominator is 90 and we have 97 for the numerator 97 fits into 90 1 time with 7 left over so the whole number would be 1 and then 7/90
Step-by-step explanation:

Answer:
C, 42 degrees
Step-by-step explanation:
Considering angle BAD is 60 degrees, that makes angle BCD also 60 degrees. Since parallelograms have 360 degrees in total, we're still missing 240 degrees. Since angles BAD and BCD are congruent (equal), that means that angles ABC and ADC also have to be congruent. To find their angles, we do 240 divided by 2, which equals 120. Now that we know all of the angles, lets focus on angle ADC. Since angle 1 has been given to us, all we need to do is subtract 78 from 120 which turns out to be 42 degrees, which is the answer.

Step-by-step explanation:
Your grandmother has given you a gift of $1500 for your birthday. You are thinking about your future and
considering two different options on how to manage your money. Option A: You take all of your $1500 and
deposit it into a savings account that has a 5% interest rate per year. Option B: You spend $500 on a new
Apple Watch and deposit the remaining $1000 in a savings account that has a 5.5% interest rate per year.
.
Which account would have the most in 10 years? 20 years? Mathematically, explain your reasoning.
Which option would you choose and why?
.
Answer:
B
Step-by-step explanation:
if you put the rest of your money in a savings account you can use that money for your college fund or maybe buy a car ect.
Answer:
OPTION A yields the most money at 10 and 20 years. Hence Option A is the better choice for "thinking about your future"
Step-by-step explanation:
In the absence of any more information, I am going to assume that Simple Interest applies. (see attached)
hence the applicable formula is:
A = P(1+rt), where
A = final amount after t years
P = Principal (beginning) amount ($1500 for option A and $1000 for option B)
r = annual interest rate (5% = 0.05 for option A and 5.5% = 0.055 for option B)
t = time (we are asked to evaluate t = 10 years and t = 20 years)
For option A :
P = $1500 and r = 5% = 0.05
A = P(1+rt)
A = 1500 [ 1 + (0.05)t]
at 10 years: A = 1500 [ 1 + (0.05)(10)] = $2,250
at 20 years: A = 1500 [ 1 + (0.05)(20)] =$3,000
For option B :
P = $1000 and r = 5.5% = 0.055
A = P(1+rt)
A = 1000 [ 1 + (0.055)t]
at 10 years: A = 1000 [ 1 + (0.055)(10)] = $1,550
at 20 years: A = 1000 [ 1 + (0.055)(20)] = $2,100
Comparing all the 4 results above, we can see that OPTION A yields the most money at 10 and 20 years. Hence Option A is the better choice for long term returns.
