Jessica needs to make a necklace for 3 of her friends, including her. she wants to use 4.5 inches of string for each necklace. she only has 10 inches of string. How many necklaces can she make and How many more string does she need to buy?
Answer:
She can make two necklaces with 10 inches. 8 more inches
Step-by-step explanation:
Answer:
She can make 2.2 Necklaces, and needs 3.5 more inches of string.
Step-by-step explanation:
Let's carefully read the problem for information we need.
3 Friends, 4.5 Inches per friend. She only has 10 inches.
If each necklace is 4.5 inches, we need
4.5 (friend one) + 4.5 (friend 2) + 4.5 (friend 3). We can also just take 4.5 * 3 friends and get the same result. This equals 13.5.
But wait! We only have 10 inches... Jessica needs 3.5 more inches of string to be able too complete the 3rd necklace. This is the answer to "How much more string does she need to buy"
---
For "How many necklaces can she make". Well, we know she can't make a full 3 necklaces. We can find out the answer to this by dividing the 10 inches she does have, by the 4.5 inches it takes to make one necklace.
10/4.5=2.2
This means she could make 2 necklaces, and 2/10 (.2) of another necklace before she runs out of string.

Jamie has a jar of coins containing the same number of nickels, dimes and quarters. The total value of the coins in the jar is $13.20. How many nickels does Jamie have?
Answer: 33
5x+10x+25x= 1320 or 40x= 1320
Jamie has 33 nickels.
Explanation:To find out how many nickels Jamie has, we need to set up an equation.
Let's assume Jamie has x nickels. Since Jamie has an equal number of nickels, dimes, and quarters, he also has x dimes and x quarters.
The value of x nickels is 5x cents, the value of x dimes is 10x cents, and the value of x quarters is 25x cents.
According to the problem, the total value of all the coins is $13.20, which is equal to 1320 cents.
So we can write the equation as follows: 5x + 10x + 25x = 1320.
Combining like terms, we get 40x = 1320. Dividing both sides by 40, we find that x = 33.
Therefore, Jamie has 33 nickels.

find MI if MB = x+9 and IB = 2x–7
Answer:
MI = -x+16
Step-by-step explanation:
MI + IB = MB
MI + 2x-7 = x+9
Subtract 2x from each side
MI + 2x-7 -2x = x+9-2x
MI -7 = -x+9
Add 7 to each side
MI -7+7 = -x+9+7
MI = -x+16
The length of segment MI can be found by adding the lengths of segments MB and IB together, resulting in MI = 3x + 2.
Explanation:This problem relates to the concept of line segments in geometry. Line MB and IB are parts of a straight line where M, I and B are points on the line. Given that MB = x + 9 and IB = 2x - 7, we realize that MB + IB = MI.
To solve this problem, you simply add the equations of the two line segments together because the total length segment MI would be the sum of segments MB and IB:
So, MI = MB + IB = (x + 9) + (2x - 7).
Then, simplify the equation by performing the addition:
MI = 3x + 2.

Mr Ortiz oversees the distribution centers for a shipping company. He recently introduced new processes at 2 centers which saved the company 2.4 million Mr. Ortiz plans to introduce the same cost saving processes at all 16 of the company's aistrubution centers. What is the total amount of money that the company can be expected to save
Answer:
19.2 million.
Step-by-step explanation:
Let us find the amount of savings per center by dividing 2.4 by 2.
[tex]\text{Amount of savings per center}=\frac{2.4\text{ Million}}{2\text{ Center}}[/tex]
[tex]\text{Amount of savings per center}=1.2\frac{\text{ Million}}{\text{ Center}}[/tex]
Hence, the company saved 1.2 million per center.
Let us multiply savings of each center by total number of company's distribution centers to find the total amount of money that the company can be expected to save.
[tex]\text{Total amount of company's savings}=(1.2\times 16)\text{ million}[/tex]
[tex]\text{Total amount of company's savings}=19.2\text{ million}[/tex]
Therefore, Mr. Ortiz's company will save 19.2 million.
The ratio of boys to girls in a tennis camp is 3:5. If there are 64 campers, how many are girls?
Answer:
There are 40 girls and 24 boys in the camp
Step-by-step explanation:
let [tex]b[/tex] be the number of boys and [tex]g[/tex] be the number of girls in the camp, then when know that
[tex]\dfrac{b}{g} = \dfrac{3}{5}[/tex] (this says that the ratio of boys to girls is 3: 5)
And since there are a total of 64 campers, we have
[tex]b+g =64[/tex] (this says that the total number of boys an girls must 64)
Thus, we have two equations and two unknowns:
[tex](1). \: \: \dfrac{b}{g} = \dfrac{3}{5}[/tex]
[tex](2). \: \:b+g =64[/tex]
and we solve this system by first solving for [tex]b[/tex] in equation (1):
[tex]b= \dfrac{3}{5}g,[/tex]
and substituting it into equation (2):
[tex]\dfrac{3}{5}g+g=64[/tex]
solving for [tex]g[/tex] we get:
[tex]\boxed{g=40}[/tex].
Putting [tex]g=40[/tex] into equation (2), we solve for [tex]b[/tex] to get:
[tex]b+40=64[/tex]
[tex]\boxed{b=24}[/tex]
Thus, there are 40 girls and 24 boys in the camp.

What is a counterexample for the conjecture?
Conjecture: Any number that is divisible by 2 is also divisible by 4.
A: 32
B: 12
C: 40
D: 18
Let's go through the list of values and test the claim
Is 32 divisible by 2? Yes because 16*2 = 32. Is it also divisible by 4? Yes because 8*4 = 32. So we can cross choice A off the list
Is 12 divisible by 2? Yes because 6*2 = 12. Is it also divisible by 4? Yes because 3*4 = 12. So we can cross choice B off the list.
Is 40 divisible by 2? Yes because 2*20 = 40. Is it also divisible by 4? Yes because 4*10 = 40. Choice C is also crossed off the list.
Is 18 divisible by 2? Yes because 2*9 = 18. Is it also divisible by 4? No. We can see that by dividing 18/4 = 4.5 which is not a whole number result. Or you can list out the multiples of 4 which are 4, 8, 12, 16, 20 and we see that 18 is not on the list.
So choice D) 18 is the answer. This is a counter example to show that the claim "if number is divisible by 2, then it is also divisible by 4" is a false statement.
The required counterexample for the conjecture is 18. which is the correct answer that would be an option (D).
What is the divisibility rule?The divisibility rule states that " Divisible By, implies that when two numbers are divided, the result would be a whole number.
For example divisibility rule of 3 is that the sum of the digits should be 3.
A counterexample for the conjecture is 18. This is a counterexample because 18 is divisible by 2 (it is an even number), but it is not divisible by 4.
Therefore, the statement "any number that is divisible by 2 is also divisible by 4" is false, because there are some numbers (like 18) that are divisible by 2 but not by 4.
Thus, the required counterexample for the conjecture is 18.
Hence, the correct answer would be an option (D).

find two irrational numbers between 0.3 and 0.7?
Answer:
0.3101001000......
0.410100100010000....
Step-by-step explanation:
To find irrational number between any two numbers, we first need to understand what a rational and irrational number is.
Rational number is any number that can be expressed in fraction of form [tex]p/q[/tex]. Since q can be 1, all numbers that terminate are rational numbers. Example: 1, 12.34, 123.66663
Irrational number on the other hand can't be expressed as a fraction and do not terminate. Also, there is no pattern in numbers i.e. there is no repetition in numbers after the decimal point.
For example: 3.44444..... can be expressed as rational number 3.45.
But 3.414114111.... is an irrational number as there no pattern observed. Also,it does not terminate.
We can find infinite number of irrational numbers in between two rational numbers.
Irrational numbers in between 0.3 and 0.7:
0.3101001000......
0.410100100010000....
0.51010010001.......

A metalworker has a metal alloy that is 20% copper and another alloy that is 60% copper. How many kilograms of each alloy should the metalworker combine to create 80 kg of a 52% copper alloy?
Answer:
16 kg of I type and 64 kg of II type should be mixed.
Step-by-step explanation:
Given that a metal alloy in original has 20% copper and 80% other metals.
Another mixture contains 60% copper and 40% other metals.
We have to get a new alloy of 80 kg which has 52% copper.
Let us assume that we mix x kg of I alloy and y kg of second alloy.
Then we have x+y = total weight = 80 kg.
x+y = 80 ... (i)
Next condition is that new alloy has 52% copper in it
When we mix x kg of I, and y kg of II, copper content would be
0.2x+0.6y. This equals 52% of 80 = 41.6
Or Dividing by 0.2 we get
x+3y =208 ... (ii)
(ii)-(i) gives 2y = 128 or y =64 kg
x = 16 kg
16 kg of I type and 64 kg of II type should be mixed.
Verify:
Copper in new alloy = 16(0.2) + 64(0.6) = 3.2+38.4 = 41.6
= 52% of 80

These points are connected by a line. The label on the x axis is Bunches of Thyme. The title on the y axis is Price of Bunches. sorry i dont know how to put pictures in
True
False
Answer:
False that the answer
Proportional relationships occur when the ratio between two quantities is constant. The provided details of the graph suggest a proportional relationship, but there could be an error— the point (8,27) doesn't follow the same ratio. Please double-check this point.
Explanation:Based on the provided details of the graph, we can infer that we have a proportional relationship, which exists when the ratio of the values of two quantities always remains the same. For example, in the graph, every two 'Bunches of Thyme' corresponds to a $6 increase in the 'Price of Bunches'. This constant ratio (1 bunch: $3) is characteristic of a proportional relationship.
So, the graph indeed represents a proportional relationship. The coordinates of the points (2, 6), (4, 12), (6, 18), and (8, 24), etc., fit the pattern y = 3x, which is another typical sign of a proportional relationship along the axis.
But it looks like there might be a mistake in your graph details because the point (8,27) doesn't fit the pattern y=3x. For x = 8, y should be 24 instead of 27. If that's not a typo, the graph doesn't represent a proportional relationship.

A taxicab ride costs $2.50 plus $1.10 per mile. If the total cost of the trip is $21.20, how many miles did the passenger travel? Let x represent the number of miles
Answer: The passenger will travel 17 miles.
Step-by-step explanation:
Since we have given that
