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.

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.

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.

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).

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).

The garden has a total of 14,208 plants, calculated by multiplying the area of the garden (3552 square feet) by the number of plants per square foot (4).

The student asked how many total plants are in a gardener's garden, which measures 96 feet long and 37 feet wide, with 4 plants per square foot. To determine the total number of plants, we must first find the area of the garden by multiplying the length and width.

The area of the garden in square feet is 96 feet × 37 feet = 3552 square feet. Since there are 4 plants per square foot, the total number of plants is 3552 × 4 = 14,208 plants.

Answer: The passenger will travel 17 miles.

Step-by-step explanation:

Since we have given that

Cost of a taxicab ride = $2.50

Cost of per mile = $1.10

Total cost of the trip = $21.20

Let number of miles the passenger travel be x

According to equation,

[tex]2.50+1.10x=\$21.20\\\\1.10x=\$21.20-\$2.50\\\\1.1x=18.7\\\\x=\frac{18.7}{1.1}\\\\x=17\ miles[/tex]

Hence, the passenger will travel 17 miles.

Answer:

Wax required for entire car = 3/8 bottle of wax

Step-by-step explanation:

We have given,

1/4 bottle of car wax can wax 2/3 of her car.

We need to find the wax required to wax her car completely.

Let's derive the relation between wax bottle and car waxing rate:

2/3 of car waxing needs 1/4 of bottle of wax.

for entire car waxing, i.e 1 car waxing needs (1/4) / (2/3) bottle of wax

            wax required for entire car     =    (1/4 )*(3/2)

                                                              =3/8 bottle of wax

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

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.

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.

5x+10x+25x= 1320 or 40x= 1320

Jamie has 33 nickels.

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.
