Sean spends 35 minutes revising for his exam. Erica spends 1 hours 15 minutes revising for her exam. Work out the total time, in minutes, spent revising by Sean and Erica. please help ASAP​

Answers

Answer 1

The total time spent in minutes is 110 minutes

How to determine the total time?

The given parameters are:

Erica = 1 hour, 15 minutesSean = 35 minutes

The total time is calculated as:

Total = Erica + Sean

So, we have:

Total = 1 hour, 15 minutes + 35 minutes

1 hour = 60 minutes

So, we have:

Total = 60 minutes + 15 minutes + 35 minutes

Evaluate the sum

Total = 110 minutes

Hence, the total time spent is 110 minutes

Answers

Answer:

a. 1

Step-by-step explanation:

The question requires us to find the value of the function g(x) when x is -3.

g(x)= -2x -5

This means that for the function of g, when the input value is x, the output value is -2x -5.

For g(-3), x takes on the value of -3. We can thus evaluate the value of g(-3) by replacing x by -3 in the expression -2x -5.

g(-3)

= -2(-3) -5

= 6 -5

= 1

Adnan began with a number. he divided his number by 2, subtracted 6 from the quotient, took the square root of the difference, added 1 to the square root, and took the square root of the sum. his final result was 3. what was adnan's original number

Answers

Answer:

140

Step-by-step explanation:

To solve this, we must reverse all the steps Adnan took to get the final number of 3.

If the last thing he did was take the square root, we need to square 3 to get the result. [tex]3x^{2} =9[/tex], so the sum they are referring to in the prompt is 9.

Before that, it says he added 1, so we need to subtract 9-1=8 to get the previous number.

It says that he took the square root before that, so we need to square 8 to get [tex]8x^{2} =64[/tex].

It says that he subtracted 6 to get this number, so we have to add 6 to get[tex]64+6=70[/tex].

Since the first thing Adnan did was divide his number by 2, we must multiply 70 by 2 to get Adnan's original number: [tex]70*2=140.[/tex]

Adnan's original number was 140.

If you roll a dice four times, what is the chance that you roll a 2?

Answers

Answer:

  about 51.77%

Step-by-step explanation:

The probability you will roll a 2 is the complement of the probability you will not roll a 2.

__

p(no 2)

A die has 6 faces, one of which is labeled with 2. The probability of rolling a 2 on any given roll is 1/6, so is 1-1/6 = 5/6 that a 2 will not be rolled. Sequential rolls of the die are presumed to be independent, so the probability of 4 rolls not showing a 2 at any time is ...

  p(no 2) = (5/6)^4 = 625/1296

p(2)

The probability that at least one 2 will show up on at least one roll is the complement of this value:

  p(some 2) = 1 -625/1296 = 671/1296 ≈ 0.517747

The chance you will roll at least one 2 is about 51.77%.

There are 4 quarters, 5 nickels and 3 dimes in a jar. One coin is randomly drawn,
replaced and then another coin is drawn.
What is the probability of getting a quarter then a nickel?
5/36
9/12
9/144
1/5

Answers

Answer:

[tex]\displaystyle\frac{5}{36}[/tex]

Step-by-step explanation:

Probability is used to find how likely an outcome is to happen. Probability can be expressed as a fraction with the total outcomes as the denominator and the number of successful outcomes (what you want to happen) as the numerator.

Sample Size

The sample size is the number of possible outcomes. In this case, the sample size will be the total number of coins. To find the sample size we need to add together all of the coins.

4 + 5 + 3 = 12

This means that the sample size is 12. For this type of probability, the sample size will serve as the denominator for each probability.

Replacement

In the question, it is stated that coins are replaced. This means that the sample size will not change at any point. So, the denominator will be the same for every probability.

Creating Probability Fractions

We are looking for the probability of getting a quarter and nickel, so we need to find the fractions that represent both situations.

First, let's find the quarter. As stated in the first paragraph, the number of successful outcomes is the numerator. There are 4 quarters, so 4 is the number of successful outcomes. Therefore, 4 will be the numerator. Then, 12 will be the denominator because 12 is the sample size.

[tex]\displaystyle\frac{4}{12}[/tex]

Next, we need to find the probability of a nickel. Since there are 5 nickels, there are 5 successful outcomes. Then, the sample size is still 12 because there is replacement.

[tex]\displaystyle\frac{5}{12}[/tex]

Complex Probability

Now we have the probability of both a quarter and nickel alone. However, this question asks about the probability of both, so this is an example of complex probability. To find complex probability, you have to multiply each probability together.

[tex]\displaystyle\frac{4}{12} *\frac{5}{12}=\frac{20}{144}[/tex]

To reach the final answer we have to simplify the answer.

[tex]\displaystyle\frac{20}{144} =\frac{5}{36}[/tex]

This means that the probability of pulling a quarter and then a nickel is 5/36.

Answer:

a) 15:7

b) 1950 ml

c) There were 10 people in the group

Step-by-step explanation:

a) In its basic form, the ratio would be 750:350. However, to get it to it's most basic form, we must find the greatest common factor (GCF) of 750 and 350, which is 50. Then, we divide both numbers by the GCF so that 750 is 15 and 350 is 7. Therefore, the basic form of the ratio is 15:7.

b) First, we can find the amount of chicken stock needed for 12 people, which is just double of the recipe since the recipe is for 6 people. (900 * 2 = 1800). Then, we need to figure out how much chicken stock is required for one person since there are 13 and not 12. We can do this by multiplying 900 by 1/6 (since it's for 1 person out of the 6 people recipe) to get 150. Then, add the amount of chicken stock needed for 12 people and 1 person together. 1800 + 150 = 1950.

c) First, we must figure out how many grams of leeks are required for just one person. We can do this by taking the amount needed in the recipe (for 6 people) and dividing it by 6 to get the amount needed for 1 person. 750 divide by 6 is 125, so 125 g of leeks are required to make soup for 1 person. Then, we take the total amount of leeks that Delia used (1250) and divide that by 125 to get 10.

Given mn, find the value of x.
(7x-7)°
(6x+11)°

Answers

Answer:

x = 18

Step-by-step explanation:

the 2 angles are alternate exterior angles and are congruent, then

7x - 7 = 6x + 11 ( subtract 6x from both sides )

x - 7 = 11 ( add 7 to both sides )

x = 18

Answer:

18

Step-by-step explanation:

(7x-7)° = (6x+11)°------ (alternate exterior angles are equal)

Alternate exterior angles are the pair of angles that are located on the outer side of the parallel lines but on either side of the transversal.

therefore,

7x-7= 6x+11

collect like terms

7x-6x = 11+7
