math a scientist uses a submarine to study ocean life she begins at sea keve which is and elevation of 0 ft she travels straight down for 80 seconds at my a speed of 4.0 ft per second she travles directly up for 20 seconds at a speed if 3.4 ft per second write an integer that represent a the submarines location after 100 seconds period plz answer before 8pm

Answers

Use the formula rate x time = distance


(rate going down)(time going down) = distance going down
(4.0 ft/s)(80 s) = 320 ft

Similarly,
(3.4 ft/s)(20 s) = 68 ft

distance traveled downward + distance traveled upward = total distance or location

320 feet + 68 ft = 388 feet below sea level

The Skubic family and the Shaw family went on a safari tour in which they drove their own vehicles through the park to view the animals. 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

Fourteen percent of the town's population are above the age of 65. if there are 320 residents over the age of 65,approximately what is the town's population?

Answers

So if 14% are over 65, and 320 residents are over 65, then we can say that 14% of the town is 320. Then, we can divide by 14 to find 1%, which is 22.857142857 Now we can multiply this by 100 to get 2285.7142857, which is the answer. To double check, you'd just find 14% of 2285.7142857 (multiply by 0.14) which is equal to 320. Because you can't have fractions of people, however, you'd have to round the answer up to 2286 people. Hope this helps!
14% of the towns population is 320. Let P denote the towns population.
14/100 * P =320
14P/100 = 320
14P = 32000
divide both sides by 14
P = 2285.71
the towns population is 2286

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.

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

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.

Choose one integer just less than 232.5 and one integer just greater than 232.5.

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?"

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.

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 jet flies at an altitude of 52, 800 feet what is the height of the jet in miles

Answers

Easy. The answer is 10 miles

The jet flies at an altitude of 10 miles, which is the result of dividing the given altitude of 52,800 feet by the number of feet in a mile (5,280).

To find the height of the jet in miles, we need to convert the altitude from feet to miles. There are 5,280 feet in a mile. So we will divide the jet's altitude in feet by the number of feet in a mile to get the altitude in miles.

Altitude in miles = Altitude in feet \/ Number of feet in a mile

Altitude in miles = 52,800 feet \/ 5,280 feet per mile

Altitude in miles = 10 miles

Therefore, the jet flies at an altitude of 10 miles.

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 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.
