If Jason ran 1.8 miles and Josh ran
3,200 yards, who ran the farthest?
(1 mile = 5,280 feet)

Answers

Answer 1

Answer: Josh ran the farthest.

Step-by-step explanation:

1 mile = 5,280 feet

1.8 miles = 1.8 x 5,280 feet = 9,504 feet

1 yard = 3 feet

9,504 feet = 9,504 / 3 yards = 3,168 yards

So Jason ran 3,168 yards.

Since 3,200 yards is greater than 3,168 yards, Josh ran the farthest.

Answer 2

Answer:

Josh ran further

Step-by-step explanation:

I converted Josh's yards to miles.

[tex]\frac{3200yards}{1 }[/tex] · [tex]\frac{3 feet}{1 yard}[/tex] · [tex]\frac{1 mile}{5280feet}[/tex]  cancel out the words that you see on the top and on the bottom

[tex]\frac{3200}{1}[/tex] · [tex]\frac{3}{1}[/tex] [tex]\frac{1mile}{5280}[/tex]  Now simplify by multiplying

[tex]\frac{9600 miles}{5280}[/tex] = 1.8181... This is a repeating number

1.8181... is larger than 1.8

Georgia has been saving her earnings from her lemonade stand. Georgia has 80 dollars to spend. If she buys a new hat for 22 dollars, how many bows can she buy with the remaining money if they cost 5 dollars each?

Answers

Answer:

Step-by-step explanation:

Because she bought a new hat for 22 dollars, subtract that from the 80 dollars.

1. 80-22=58

Next, each bow costs 5 dollars so you’ll have to see how many times 5 goes into 58 to get your answer.

2. 58/5= 11 with three dollars remaining.

That means Georgia can purchase 11 bows with the remaining money.

Answer:

Step-by-step explanation:

Because she bought a new hat for 22 dollars, subtract that from the 80 dollars.

2. 58/5= 11 with three dollars remaining.

That means Georgia can purchase 11 bows with the remaining money.

She can buy 11 because she has 80 minus 22 for the hat, 80-22= 58

5x11 = 55
She would have 3$ left which isn’t enough for a hat

Part A

c = 66 per dress

Part B

$396

Okay, here are the step-by-step calculations:

Part A:

You were given the number 66. So we entered that as the cost (c) per dress in the equation.

Part B:

We were asked to find the cost of 6 dresses.

So we calculate:

Cost per dress (c) = $66

Number of dresses = 6

Total cost of 6 dresses =

$66 x 6 = $396

So the final answer for Part B is: $396

In summary:

We were given: Cost per dress (c) = $66

and asked for cost of 6 dresses

So we calculated: Cost per dress (c) = $66

Number of dresses = 6

Total cost = $66 x 6 = $396

Answer:

A factor of 4 can only be 4 itself, which is one of the possible outcomes of rolling a 6-sided dice.

Therefore, the probability of getting a factor of 4 when rolling a 6-sided dice is:

P(getting factor of 4) = 1/6

probability of rolling ________
(a) a 1 and then a 6
(b) an even number and then an odd
number
(c) a number less than 3 and then a
number greater than 3


Write the probability as a reduced fraction

Answers

Answer:

Part - A = 1/36

Part - B = 1/4

Part - C = 1/6

Step-by-step explanation (Part - A):

The numbers on the cube are, 1 , 2 , 3 , 4 , 5 and 6.

Formula to calculate probability =
Total Number of the particular number / Total Number of Numbers

The probability of rolling 1 is 1/6 as there is only one 1 in a numbered cube.

The probability of rolling 6 is 1/6 as there is only one 6 in a numbered cube.

So, the probability of rolling 1 and 6 is 1/6 * 1/6.

The probability of rolling 1 and 6 = 1/36.


Step-by-step explanation (Part - B):

The numbers on the cube are, 1 , 2 , 3 , 4 , 5 and 6.

Formula to calculate probability =
Total Number of the particular number / Total Number of Numbers

The probability of rolling an even number is 3/6 = 1/2 because there are 3 even numbers in a numbered cube.

The probability of rolling an odd number is 3/6 = 1/2 because there are 3 odd numbers in a numbered cube.

So, the probability of rolling an even and an odd number is 3/6 * 3/6 = 1/2 * 1/2.

The probability of rolling an even and an odd number = 9/36 = 1/4.


Step-by-step explanation (Part - C):

The numbers on the cube are, 1 , 2 , 3 , 4 , 5 and 6.

Formula to calculate probability =
Total Number of the particular number / Total Number of Numbers

The probability of rolling a number that is less than 3 is 2/6 = 1/3 because there are 2 numbers that are less than 3 in a numbered cube.

The probability of rolling a number that is greater than 3 is 3/6 = 1/2 because there are 3 numbers that are greater than 3 in a numbered cube.

So, the probability of rolling a number that is less than 3 and a number that is greater than 3 is 2/6 * 3/6 = 1/3 * 1/2.

The probability of rolling a number that is less than 3 and a number that is greater than 3 is 6/36 = 1/6.

Construct a triangle with a 70 degree angle, a 85 degree angle, and a 105 degree angle. Did you construct a triangle, if so what type of trianlge is it?

Answers

Answer:

no triangle

Step-by-step explanation:

The sum of the measures of a triangle is 180°.

70° + 85° + 105° = 260°

Since the sum of the given measures is 260°, no triangle with these angle measures can be constructed since it cannot exist.

No because a triangle is 180. These three numbers equal 260.

The names of the months of the year
were written on separate papers and
placed in a hat. Two papers are ran-
domly drawn one at a time, replacing
the first before the second draw. What
is the probability of drawing. ?
(a) April and then June
(b) a month ending in r and then a
month ending in y
(c) May and then not drawing May


Write the probability as a reduced fraction

Answers

Step-by-step explanation:

There are 12 months of the year, so there are 12 possible choices for each draw. Since the first paper is replaced before the second draw, each draw can be considered as independent and with replacement.

(a) To draw April and then June, we need to draw April on the first draw (with probability 1/12), and then June on the second draw (with probability 1/12). The probability of both events happening is the product of their probabilities:

P(April and then June) = (1/12) x (1/12) = 1/144

(b) To draw a month ending in r and then a month ending in y, we can choose from the following months: April, June, July, September, and November. There are 5 months that end in r, so the probability of drawing one of them on the first draw is 5/12. After replacing the first paper, there are still 12 months left in the hat, but now we want to draw a month ending in y. There are 4 months that end in y, so the probability of drawing one of them on the second draw is 4/12. Again, the probability of both events happening is the product of their probabilities:

P(month ending in r and then month ending in y) = (5/12) x (4/12) = 5/36

(c) To draw May on the first draw and not draw May on the second draw, the probability of drawing May on the first draw is 1/12, and the probability of not drawing May on the second draw is 11/12 (since there are 11 months left in the hat after May is drawn on the first draw). Again, the probability of both events happening is the product of their probabilities:

P(May and then not drawing May) = (1/12) x (11/12) = 11/144

Therefore, the probabilities are:

(a) 1/144

(b) 5/36

(c) 11/144

Step-by-step explanation:

There are 12 months of the year, so there are 12 possible choices for each draw. Since the first paper is replaced before the second draw, each draw can be considered as independent and with replacement.

(a) To draw April and then June, we need to draw April on the first draw (with probability 1/12), and then June on the second draw (with probability 1/12). The probability of both events happening is the product of their probabilities:

P(April and then June) = (1/12) x (1/12) = 1/144

(b) To draw a month ending in r and then a month ending in y, we can choose from the following months: April, June, July, September, and November. There are 5 months that end in r, so the probability of drawing one of them on the first draw is 5/12. After replacing the first paper, there are still 12 months left in the hat, but now we want to draw a month ending in y. There are 4 months that end in y, so the probability of drawing one of them on the second draw is 4/12. Again, the probability of both events happening is the product of their probabilities:

P(month ending in r and then month ending in y) = (5/12) x (4/12) = 5/36

(c) To draw May on the first draw and not draw May on the second draw, the probability of drawing May on the first draw is 1/12, and the probability of not drawing May on the second draw is 11/12 (since there are 11 months left in the hat after May is drawn on the first draw). Again, the probability of both events happening is the product of their probabilities:

P(May and then not drawing May) = (1/12) x (11/12) = 11/144

Therefore, the probabilities are:

(a) 1/144

(b) 5/36

(c) 11/144

O (D) charismatic. A sports car travelling at uniform speed of 30 m s- passes a police van which is cruising at 15 m s-. The van, accelerating at the rate of 1.2 m s-2, immediately begins to chase the car. (i) Write down expressions for the distance, s, travelled by each vehicle in t second, and hence (ii) calculate the time required for the van to overtake the car. The equilibrium constant for the reaction A(g) B(g)is 102. A reaction mixture initially contains [A] = 22.4M and [B] = 0.0M. Which statement is true at equilibrium?a. The reaction mixture contains[A] = 1.0M and [B] = 21.4M. b). The reaction mixture contains [A] = 22.2M and [B] = 0.2M. c). The reaction mixture contains [A] = 0.2Mand [B] = 22.2M. d). The reaction mixture contains [A] = 11.2M and [B] = 11.2M. the active ingredient in a common treatment for upset stomach is sodium bicarbonate, nahco3. calculate the percent, by mass, of sodium in sodium bicarbonate. List the variables that lead to (a) band broadening and (b) band separation in gas-liquid chromatography.
