I have 4 times as many hats as my brother. Together we have 50 hats. How many hats do we each have?

Answers

Answer 1
x = ur hats, y = ur brothers hats
x + y = 50
x = 4y

4y + y = 50
5y = 50
y = 50/5
y = 10 <== ur brother has 10 hats

x + y = 50
x + 10 = 50
x = 50 - 10
x = 40 <== u have 40 hats
Answer 2
x=your number of hats
y=number of hats bro has

x is 4 times y
x=4y
together (x+y) it is 50

x+y=50
since x=4y, replace x with fy
4y+y=50
5y=50
divide both sides by 5
y=10
x=4y
x=4(10)
x=40

you have 40 and bro has 10

A dime weighs about 1/12 ounce jody has 1 pound of dimes (16 ounces) about how many dimes does jody have

Answers

1/12 is what a dime weighs so that's means 12 dimes weighs 1 ounce so if 16 oz is one pound do 12x16 and you will get the answer

Jody has approximately 192 dimes in 1 pound, calculated by first determining that 1 ounce equates to 12 dimes and then multiplying by the total ounces in a pound.

To determine how many dimes Jody has in 1 pound (16 ounces), we'll use the given information that a dime weighs about 1/12 ounce. First, we find the total number of dimes in one ounce:

1 ounce / (1/12 ounce per dime) = 12 dimes.

Now, since there are 16 ounces in a pound, we multiply the number of dimes in one ounce by the total ounces:

12 dimes per ounce * 16 ounces = 192 dimes.

Therefore, Jody has approximately 192 dimes in 1 pound.

a graph shows the elements found in earths crust. what fraction of earths crust is silicon.

Answers

The fraction of Earth's crust that is silicon is 0.28, which can also be written as 28/100 or 28%.

To determine the fraction of Earth's crust that is silicon, we need to convert the percentages into fractions.

The percentages:

Oxygen: 47%

Silicon: 28%

Aluminum: 8%

Other: 17%

To convert these percentages into fractions, we divide each percentage by 100:

Oxygen fraction = 47/100 = 0.47

Silicon fraction = 28/100 = 0.28

Aluminum fraction = 8/100 = 0.08

Other fraction = 17/100 = 0.17

Now, to find the fraction of Earth's crust that is silicon, we divide the silicon fraction by the sum of all the fractions:

Silicon fraction / (Oxygen fraction + Silicon fraction + Aluminum fraction + Other fraction)

0.28 / (0.47 + 0.28 + 0.08 + 0.17)

0.28 / 1

Therefore, the fraction of Earth's crust that is silicon is 0.28, which can also be written as 28/100 or 28%.

The ratio of Joey's Rope to chads rope is 16:6 . Joeys rope is 112 cm long . How long is chads rope ?

Answers

the answer would be 17.920 because 112 multiplied by 16.6 would equal 17.920
Final answer:

To find the length of Chad's rope, the ratio of 16:6 was simplified to 8:3, and using Joey's rope length of 112 cm, we found out that Chad's rope is 42 cm long.

Explanation:

The question asks to find out the length of Chad's rope given the ratio of Joey's rope to Chad's rope is 16:6 and Joey's rope is 112 cm long. To solve this, we should first simplify the given ratio to its lowest terms. The ratio can be simplified to 8:3, by dividing both numbers by 2. If Joey's rope is 112 cm (which corresponds to 8 parts of the ratio), then each 'part' of the ratio represents 112 cm divided by 8, which is 14 cm. Since Chad's rope corresponds to 3 parts of this ratio, the length of Chad's rope is 3 times 14 cm, which equals 42 cm.

the cost of peanuts varies directly with the number of pounds bought.If 5 pounds costs $7.50, find the cost of 3 pounds.

Answers

3 pounds of peanuts must cost $4. 50 because the unit price is $1. 50 times 3 equals $4. 50

The cost for 3 pounds of peanuts is found by first determining the cost per pound from the 5 pound price, which is $1.50 per pound. Multiplying this rate by 3 pounds gives us the total cost of $4.50.

If the cost of peanuts varies directly with the number of pounds bought, this means you can find the cost per pound and then use it to calculate the price for any amount of peanuts. Given that 5 pounds costs $7.50, first we calculate the cost per pound:

Cost per pound = Total cost / Number of pounds = $7.50 / 5 pounds = $1.50 per pound.

Now, to find the cost of 3 pounds of peanuts, we multiply the cost per pound by the number of pounds:

Cost of 3 pounds = $1.50 per pound * 3 pounds = $4.50.

Therefore, the cost of 3 pounds of peanuts is $4.50.

2. Find the Least Common Denominator (8).
31/4 * 2/2 becomes 62/8

1. There is a total of 62 tennis balls. A long tube can hold 5 balls. A short tube can hold 3 balls. How many tubes are there?
2. Find the consecutive numbers whose sum is 465.
I'm awarding 35 points, with a Brainliest Answer.

Answers

1. I assume that you must have full tubes of 5 balls and of 2 balls. I also assume you are looking for the least number of tubes.

To fit the balls in only tubes of 5, you'd need:
62/5 = 12.4, or more than 12 tubes, but fewer than 13.

If you used 12 tubes of 5, you'd fit 60 balls. Then one tube of 3 balls would only have 2 balls.

Try 11 tubes of 5. That fits 55 balls. There are 7 left, but 7 is not divisible by 3.

Try 10 tubes of 5. That fits 50 balls. There are 12 balls left. 12 is divisible by 3.
12/3 = 4.

That means you need 10 tubes of 5 and 4 tubes of 3 to have the smallest number of tubes possible.

2. If you are looking for 2 consecutive integers, then let the smaller integer be x. The larger integer is x + 1.
x + x + 1 = 465
2x + 1 = 465
2x = 464
x = 232
x is the smaller integer, and it is 232. The larger integer is 233.

Here is a way to solve without using an equation learned in algebra.
The sum of the two consecutive integers is 465.
Divide 465/2 = 232.5

a board is 2/3 yard long. Jenna cut the board into pieces that are 1/6 yard long. How many pieces are there?

Answers

The answer to that equation is 4.

To determine how many 1/6 yard pieces can be made from a 2/3 yard board, divide 2/3 by 1/6. After multiplying the reciprocal of 1/6, the result is 4, meaning there are 4 pieces of 1/6 yard each.

To find out how many pieces of 1/6 yard can be cut from a 2/3 yard long board, we need to divide the total length of the board by the length of each piece. This is a division of fractions problem.

The calculation is as follows:

Write down the length of the board: 2/3 yard.

Write down the length of each piece: 1/6 yard.

Divide the length of the board by the length of each piece: (2/3) \/ (1/6).

To divide fractions, we multiply by the reciprocal of the second fraction: (2/3) * (6/1).

Multiply the numerators together: 2 * 6 = 12.

Multiply the denominators together: 3 * 1 = 3.

Simplify the fraction: 12/3 = 4.

So, Jenna can cut the board into 4 pieces of 1/6 yard each.

Lisa has 2.134 buttons that need to be sorted equally into 12 jars.How many buttons will be in each jar?

Answers

Final answer:

To find the number of buttons per jar, divide the total number of buttons (2.134) by the number of jars (12). However, the count of 2.134 buttons is likely incorrect as you cannot have a fraction of a button, indicating a potential typo or miscount.

Explanation:

The question asks how many buttons will be in each jar if Lisa has to sort 2.134 buttons equally into 12 jars. To find this, we need to divide the total number of buttons by the number of jars.

First, let's set up the division equation: 2.134 buttons ÷ 12 jars = number of buttons per jar.

Now, we calculate the number of buttons per jar: 2.134 ÷ 12 = approximately 0.1778 buttons per jar. However, since we can't have a fraction of a button, Lisa likely made an error in counting, as the number of buttons needs to be a whole number. So, assuming there's a typo, and the actual number of buttons is a whole number, Lisa would need to recount her buttons before sorting them.

Once Lisa has the correct number of whole buttons, she could repeat the division process to find the exact number of buttons per jar.

Final answer:

Each jar will contain approximately 0.1785 buttons.

Explanation:

To determine how many buttons will be in each jar, you divide the total number of buttons (2.134) by the number of jars (12). The calculation is as follows: [tex]\( \frac{2.134}{12} \approx 0.1785 \)[/tex]. Therefore, each jar will contain approximately 0.1785 buttons.

In this scenario, the division represents the distribution of buttons into equal portions, with the quotient being the number of buttons per jar. It's crucial to understand the concept of division to solve such problems. In practical terms, if you were to distribute 2.134 buttons equally among 12 jars, each jar would have approximately 0.1785 buttons. This approach ensures a fair and even distribution of the given quantity among the specified number of containers.

Overall, understanding the basic arithmetic operation of division helps solve real-world problems like distributing items equally, and in this case, finding the number of buttons per jar in Lisa's scenario.

Complete question: "Lisa has 2,134 buttons that need to be sorted equally into 12 jars. How many buttons will be in each jar?"

The cost of the tour was $5.25 per vehicle plus an additional amount for each person in the vehicle. The Skubic family had 7 people in their vehicle and paid $22.75.

Answers

The total cost for the safari tour for the Shaw family is $12.75 with a vehicle cost of $5.25 and an additional amount per head of $2.5.

let us say the additional amount for each person = Z

it is given that

cost of the tour per vehicle = $5.25

number of family members in Skubic family = 7

number of family members in Shaw family = 3

total cost = $22.75

what will be the total cost for each family?

the total cost will be the sum of the additional amount for all and vehicle cost.

Total cost for Skubic family

7z + 5.25 = 22.75(given)

7z= 17.5

z=$2.5

total cost for Shaw family = 3z+5.25 = 3*2.5+5.25 = $12.75

therefore, the total cost for the Shaw family is $12.75

solve the equation 4(2+3c)=56

Answers

2+3c=14
3c=14-2
3c=12
C=4

The solution to the equation 4(2 + 3c) = 56 is c = 4.

To solve the equation 4(2 + 3c) = 56, we will follow the order of operations (PEMDAS) to simplify the expression and isolate the variable c.

First, we distribute the 4 to both terms inside the parentheses:

4 * 2 + 4 * 3c = 56

Simplifying further:

8 + 12c = 56

Next, we want to isolate the variable c by subtracting 8 from both sides:

8 + 12c - 8 = 56 - 8

Simplifying:

12c = 48

Finally, we divide both sides by 12 to solve for c:

12c/12 = 48/12

Simplifying:

c = 4

Therefore, the solution to the equation 4(2 + 3c) = 56 is c = 4.
