The smith family took a 2-day road trip.on the second day,they drove 3/4 the distance they traveled on the first day. What is possible distance they could have traveled over the 2 days ? Is there more than one possible distance? Justify your response

Answers

Answer:

1 1/4

Step-by-step explanation:

use mixed number calcator!

The total distance traveled by the Smith family for 2 days is given by the equation A = ( 7/4 )d , where d is the distance traveled on first day

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The distance traveled by the Smith family on first day = d miles

The distance traveled by the Smith family on second day = ( 3/4 ) of the distance of first day

On simplifying the equation , we get

The distance traveled by the Smith family on second day = ( 3/4 ) d

And , the total distance traveled A = d + ( 3/4 )d

The total distance traveled A = ( 7/4 )d

The total distance traveled A = 1.75d

Hence , the equation is A = 1.75d

A company's sales in Seattle were $330,000 in 2012, while their sales in Portland were $235,000 for the same year. Complete the following statements: a. Seattle's sales were % larger than Portland's. b. Portland sales were % smaller than Seattle's. c. Portland sales were % of Seattle's. Give answers accurate to at least one decimal place.

Answers

Answer:

A) Seattle's sales were 40.42% larger than Portland's.

B) Portland sales were 28.79% smaller than Seattle's.

C)  Portland sales were 71.21% of Seattle's.

Step-by-step explanation:

Since a company's sales in Seattle were $ 330,000 in 2012, while their sales in Portland were $ 235,000 for the same year, the following calculations must be performed to complete the sentences:

A)

235,000 = 100

330,000 = X

330,000 x 100 / 235,000 = X

33,000,000 / 235,000 = X

140.42 = X

Seattle's sales were 40.42% larger than Portland's.

B)

330,000 = 100

235,000 = X

235,000 x 100 / 330,000 = X

23,500,000 / 330,000 = X

71.21 = X

100 - 71.21 = 28.79

Portland sales were 28.79% smaller than Seattle's.

C)

330,000 = 100

235,000 = X

235,000 x 100 / 330,000 = X

23,500,000 / 330,000 = X

71.21 = X

Portland sales were 71.21% of Seattle's.

A receipt for homemade pizza states that it yields 2 pizzas with 298 calories per slice 8 slices in one pizza you instead decide to make 5 mini pizzas if you eat two mini pizzas how many calories did you consume

Answers

Answer:

1,907.2 calories.

Step-by-step explanation:

We know that with a recipe and some given ingredients, you can make 2 pizzas, such that each pizza has 8 slices, then there are:

2*8 = 16 slices

And each slice has 298 calories, then the total amount of calories is:

16*298 cal = 4,768 cal.

Now, we know that you decide to make 5 mini pizzas instead (where we assume that you use the same ingredients that you would have used for the two pizzas) then the total amount of calories in the 5 mini pizzas is the same as the amount of calories in two normal pizzas, then:

in 5 mini pizzas we have 4,768 cal.

Then if each mini pizza has C calories, we have:

5*C = 4,768 cal.

we can solve this for C.

C = 4,768cal/5 = 953.6 cal

Then if you eat two of these, the total amount of calories you consume is twice that amount:

calories consumed = 2*953.6 cal = 1,907.2 cal.

34. Find each of the following probabilities when n indepen- dent Bernoulli trials are carried out with probability of success p. a) the probability of no successes b) the probability of at least one success c) the probability of at most one success d) the probability of at least two successes

Answers

Answer:

A.) (1 - p)^n

B.) 1 - (1 - p)^n

C.) (1 - p)^n + np*(1-p)^(n-1)

D.) 1 - (1 - p)^n - np*(1-p)^(n-1)

Step-by-step explanation:

General form of a binomial probability :

P(x = x) = nCx * p^x * q^(n-x)

q = 1 - p ; n = number of trials ; x = number of successes ; p = probability of success

A.) probability of no successes ;

P(x = 0) = nC0 * p^0 * (1 - p)^(n-0)

P(x = 0) = 1 * 1 * (1 - p)^n

P(x = 0) = (1 - p)^n

Probability of atleast one success = 1 - P(no success)

P(x ≥ 1) = 1 - P(x = 0)

P(x = 0) = (1 - p)^n

P(x ≥ 1) = 1 - P(x = 0) = 1 - (1 - p)^n

Probability of at most one success

P(x ≤ 1) = p(x = 0) + p(x = 1)

P(x = 0) = (1 - p)^n

P(x = 1) = nC1 * p^1 * (1 - p)^(n-1)

P(x = 1) = n * p * (1 - p)^(n-1) = np*(1-p)^(n-1)

P(x ≤ 1) = (1 - p)^n + np*(1-p)^(n-1)

Probability of atleast two successes:

(1 - probability of at most 2 successes)

P(x ≥ 2) = 1 - P(x ≤ 1)

P(x ≥ 2) = 1 - (p(x = 0) + p(x = 1))

P(x ≥ 2) = 1 - p(x = 0) - p(x = 1))

P(x ≥ 2) = 1 - (1 - p)^n - np*(1-p)^(n-1)

Bruce wants to make 50 ml of an alcohol solution with a 12% concentration. He has a 10% alcohol solution and a
15% alcohol solution.
Which equation can Bruce use to determine how much of the 10% alcohol solution he should use?

Answers

Answer:

20 ml of 15% alcohol and 30 ml of 10% alcohol should be used to create a 12% alcohol solution.

Step-by-step explanation:

Since Bruce wants to make 50 ml of an alcohol solution with a 12% concentration, and he has a 10% alcohol solution and a 15% alcohol solution, to determine how much of the 10% alcohol solution he should make the following calculations:

0.9 x 15 + 0.1 x 10 = 14.5

0.7 x 15 + 0.3 x 10 = 13.5

0.5 x 15 + 0.5 x 10 = 12.5

0.4 x 15 + 0.6 x 10 = 12

50 x 0.4 = 20

Therefore, 20 ml of 15% alcohol and 30 ml of 10% alcohol should be used to create a 12% alcohol solution.

frank has a board that is 5/8 yards long he cuts off a piece that is 3/5 the length of the board how long is the piece of the board frank cutt off?​

Answers

Answer:

Step-by-step explanation:

If the board is 5/8 of a yard, then it is 5/8 of 36 inches (a yard is 36 inches).

5/8 * 36 = 22.5 inches.

Frank now cut's 3/5 of the length of the board. So he is going to cut off 3/5 of 22.5 inches.

(3/5) * 22.5 = 67.5 / 5 = 13.5 inches.

You don't specify what the units should be. I translate this into yards, but I think if you want something else, leave a comment.

13.5 /36 = 0.375 = 3/8 of a yard.
