A geologist visits 80 volcanoes in Alaska and California. What if the 70% of the volcanoes were in California? How many would the geologist have visited in California and how many are in Alaska?

Answers

Answer 1

30 % of the Volcanoes would be going to Alaska so.... 24 volcanoes are in Alaska while 76 are in California

Answer 2

56 in California, 24 in Alaska. First you've got to divide 100 by 80 to get 1.25. Then multiply it by 30 and 70 to get 24 and 56. Hope this helped! If you need it clearer, let me know! :)

Distance to be covered by the runner is given as [tex]\frac{7}{8}.[/tex] miles.

Speed of runner= [tex]\frac{3}{8}.[/tex] miles per minute.

The Time taken can be calculated by the formula Time = Distance ÷speed.

Time taken =[tex]\frac{7}{8}.[/tex] ÷[tex]\frac{3}{8}.[/tex]

Time = [tex]\frac{7}{8} x \frac{8}{3} =\frac{7}{3}.[/tex]

the library is 4 blocks north and 9 blocks east of the school. The museum is 9 blocks east and 11 blocks south of the school. How far is it from the library to the museum?

Answers

Summary: Solve[tex] \sqrt{90} [/tex]
Starting at (0,0), the school's location, at least for the definition I will use, you add 4 to the y value (0,4), 9 blocks east, so you add 9 to the x value (9,4), and there is the library's location. Adding 9 to the x value and subtracting 11 from 4 you get (18,-7). You'll need the distance formula for the rest, which is: [tex] \sqrt({ x_{1} - x_{2})^2 + ({y_{1} - y_{2})^2[/tex]. So, plugging in the numbers, the first x becomes 9, and the second one becomes 18, so the first portion of the equation is (9-18)^2. As for the second part of the equation, you plug 4 into the first y, and -7 into the second "y", ending up with (4-7)^2. So, the equation now becomes [tex] \sqrt{(9-18)^2 + (4-7)^2} [/tex]. Using that, (-9)^2 is 81, and (-3)^2 is 9, so 81+9 is 90, and now, for the final portion of the equation, you find the square root of 90, which is about 9.49. So, the distance between the library and museum is about 9.49 (or 9.5) blocks.

A turtle walks at a rate of 1/5 mile in 45 minutes. If the turtle continues at the same rate, how much of a mile will the turtle walk in 1 hour?

Answers

Final answer:

The turtle walks at a rate of 1/5 mile in 45 minutes. By calculating the turtle's speed as 1/225 miles per minute, we find that the turtle will walk 4/15 of a mile in 1 hour.

Explanation:

The student asked how much of a mile the turtle will walk in 1 hour if the turtle walks at a rate of 1/5 mile in 45 minutes. To solve this, we calculate the speed of the turtle in miles per minute and then find out how far the turtle can go in 60 minutes (1 hour).

First, we find the turtle's speed:

The turtle walks 1/5 mile in 45 minutes. Therefore, the turtle's speed is (1/5) mile per 45 minutes. To find the speed in miles per minute, divide 1/5 by 45: Speed = (1/5) mile / 45 minutes = 1/225 miles per minute. Now we want to know how far the turtle will go in 60 minutes, so we multiply the speed by 60: Distance in 1 hour = 1/225 miles/minute * 60 minutes = 4/15 mile.

Therefore, if the turtle continues at the same rate, it will walk 4/15 of a mile in 1 hour.

Final answer:

To find out how much of a mile the turtle will walk in 1 hour, divide 1/5 by 45 to find the distance walked in 1 minute. Then multiply the distance walked in 1 minute by 60 to find the distance walked in 1 hour. The turtle will walk 1/3 of a mile in 1 hour.

Explanation:

To find out how much of a mile the turtle will walk in 1 hour, we first need to determine the distance the turtle walks in 1 minute. Since the turtle walks 1/5 mile in 45 minutes, we can divide 1/5 by 45 to find the distance walked in 1 minute:

1/5 mile ÷ 45 minutes = 1/225 mile per minute

Now, we can multiply the distance walked in 1 minute by 60 to find the distance walked in 1 hour:

(1/225 mile per minute) × 60 minutes = 1/3 mile

Therefore, the turtle will walk 1/3 of a mile in 1 hour.

Toilet paper is sold in cases of 36 rolls for $14.99. What is the price per roll (unit cost)?

Answers

Alright, so the unknown value here we want to know is the price of one roll of TP. Let's call it "x".
36x=14.99
Divide both sides by 36 to get the price of a single roll.
x=.41638888....
We have to round this to hundredths because we're talking in cents, so...
x=.42
Each roll of toilet paper costs 42 cents.

A unit cost of approximately $0.42 per roll.

To calculate the price per roll of toilet paper, we need to divide the total cost of the case by the number of rolls in the case. Here is the calculation:
Price per roll = Total cost of the case \/ Number of rolls in the case

Price per roll = $14.99/ 36

Price per roll = $0.4163888889

Therefore, the unit cost or price per roll is approximately $0.42 when rounded to the nearest cent.

A bathtub, measures 60 inches long by 30 inches wide, holds approximately 35 to 50 gallons of water.

Calculate the amount of water in your tub with a few clicks of your calculator. There is no way to calculate the “average” tub size because average means knowing about every tub everywhere, but there are typical tub sizes. The best way to know how much water your tub holds is to measure your own tub. Use the calculations to administer your hot tub chemicals or to know how much Epsom salts to add for that relaxing soak.

6 times what equals 324

Answers

6 times 54 is 324. you just have to divide 324 by 6 and to check you multiply it by the product (54) .

6 times 54 equals 324.

To find the number that, when multiplied by 6, equals 324, you can set up the equation:

6x = 324

To solve for x, you divide both sides of the equation by 6:

6x / 6 = 324 / 6

Simplifying this equation, you get:

x = 54

Therefore, 6 times 54 equals 324.
