30 + 40 = _(_+_)

3. Rewrite the sum of 30 and 42 by factoring out the greatest common factor.

Answers

Answer 1

Answer:

24+40=8(3+5)

30+40=10(3+4)

30+42=6(5+7)

Step-by-step explanation:

Look at 24 and 40 and determine the biggest number that goes into both of these numbers. Greatest(biggest) common(same) factor(number that goes into another number). Sometimes you can find the prime factorization to do this, or there's a method of listing factors. Both of these numbers are products found in a regular times table. You can run the factors using mental math to find the biggest one.

You consider the factors of 30 and 40. 10 is the biggest number that goes into both.

And 30 and 42, 6 goes into both.

The numbers that go inside the parentheses are the other factors of the two numbers you're given.

24 is 8×3. 8 is the common factor. 3 goes inside the parentheses.

40 is 8×5. 8 is the common factor. 5 goes inside the parentheses.

Answers

Answer:

9.85 - 1.15 = 8.70

Step-by-step explanation:

you jus subtract :)  

Answer:

  $1.90

Step-by-step explanation:

Let n represent the cost of a notebook. Jenna's purchase is ...

  4n +3(n -1.15) = 9.85

  7n - 3.45 = 9.85 . . . . . simplify

  7n = 13.30 . . . . . . . . . . add 3.45

  n = 1.90 . . . . . . . . . . . . divide by 7

The cost of a notebook is $1.90.

A map has a scale of 1 inch = 3 miles. Which of the following scales is equivalent?

Answers

12 inch=36 miles because if you multiply 11 x 3 you get 36 miles.

Answer:

Step-by-step explanation:

77 inches

Step-by-step explanation:

Given

1 inch = 3 miles in map

We are also given the actual distance between City A and City B = 231 miles.

In order to get the distance in inches = Distance between City A and City B in miles/ 3

We are dividing the distance by 3 to get the distance in inches.

So,

Distance on map = 231/3

= 77 inches

A standard number cube, numbered 1 through 6 on each side, is rolled 3 times. What is the probability of rolling a 2 on all three rolls? Enter the answer as a fraction

Answers

Rolling a 2 on a standard dice is 1/6. So multiply 1/6 *1/6 * 1/6= 1/36

Answer:

1/(6^3)

Step-by-step explanation:

Each roll of the die constitutes a separate event.

These three events are independent.

The probability of rolling a 2 on the first throw is 1/6, since there is only one '2' among the six numbers on the die.

Because each roll is independent of the others, the probability of rolling a

2                                                              1

on all three rolls is (1/6)(1/6)(1/6), or -----------

The y axis is a line of symmetry for a triangle. The coordinates of two of its vertices are (-3, 2) and (0,5)
A. What are the coordinates of the third vertex?

B. What is the area of the triangle?

Answers

Answer:

(3,2)

Step-by-step explanation:

since it symmetrical over the y axis it will be the same as the first point except the x will be the opposite

Answer:

See  below

Step-by-step explanation:

A)

One of the points on the y-axis (0, 5).

It means the other vertices are symmetrical:

(-3, 2) and (3, 2)

B)

The height of the triangle is the difference of the y-coordinates:

h = 5 - 2 = 3

The base of the triangle is the distance between the symmetric vertices:

b = 3 - (-3) = 6

Jimmy and his family are on their way to visit some family friends who live 780 miles away from them. Based on the route they chose, they expect to complete their trip in three days. The distances and average speeds for the first two days driven are shown below. • First day: 4 hours at an average speed of 60 miles per hour • Second day: 6 hours at an average speed of 65 miles per hour If the average speed on the third day is 60 miles per hour, how many more hours will it take for them to reach their family friends’ home?

Answers

Answer:

If they drive an average of 60 miles per hour the last day it will take them 2.5 hours.

4 hours at 60 miles per hour = 4*60 = 240 miles

6 hours at 65 miles per hour = 6*65 = 390 miles

This is a total of 630 miles.  There are 780-630=150 miles left; if they average 60 miles per hour, that would be 150/60 = 2.5 hours.

3. Marcia's estimation is closer

4. 690 people per year

Step-by-step explanation:

1. Marcia's estimation has a greater number of people because he estimated 600 people per year, while Adam estimated 2% of 12,500 (250 people per year).

2. (I do not understand what this question is asking)

3. marcias guess was 600 (600x50+12,500 = 42,500. 42,500 - 35,400 = 7,100) while Adam's guess was 250 per year (250x50+12,500 = 10,400). Therefore, Marcia's guess was closer to 35,400.

4. If Marcia adjusted her answer so that the population in Burbville was ACTUALLY going to be 34,500, she would need to adjust her estimation to 690 people per year.

Answer:

50, 40, 30, 250, 350

Step-by-step explanation:

1/2 = 0.5, 0.5 x 100 = 50 (0.5 -> 5 -> 50)

2/5 = 0.4 (10 / 5 [the denominator] = 2, 0.2 x 2 [the numerator] = 0.4), 0.4 x 100 = 40 (0.4 -> 4 -> 40)

3/10 = (10 / 10 [the denominator] = 1, 0.1 x 3 [the numerator] = 0.3), 0.3 x 100 = 30 (0.3 -> 3 -> 30)

5/2 = 2.5 (2 1/2), 2.5 x 100 = 250 (2.5 -> 25 -> 250)

7/2 = 3.5 (3 1/2), 3.5 x 100 = 350 (3.5 -> 35 -> 350)

Note: I'm not sure if I understand the question completely, but I changed the fraction into a decimal and multiplied it by 100. Not sure what it means by "Divide fraction".

According to the question , firstly we have to divide the fraction and then convert them into percentage

How to find that a given condition can be modeled by binomial distribution?

Binomial distributions consist of n independent Bernoulli trials.

Bernoulli trials are those trials that end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as

 

[tex]\rm X \sim B(n,p)[/tex]

The probability that out of n trials, there'd be x successes is given by

[tex]\rm P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]

The expected value of X is:

[tex]\rm E(X) = np\\[/tex]

A bag contains 6 red markers, 5 blue markers, and 4 green markers.

A marker is randomly selected, its color is recorded, and it is returned to the bag.

This is repeated 1050 times.

n = 1050

Then the value of p will be

[tex]p=\dfrac{^6C_1}{^{15}C_1} = \dfrac{6}{15} = 0.4[/tex]

Then the expected value will be

[tex]\rm E(X) = np\\\\\rm E(X) = 1050 \times 0.4 \\\\\rm E(X) = 420[/tex]

The movie ticket cost 10$

The amount of money that can be spent on food can be represented by d

the amount of money that can be spent on food plus the cost of the ticket (10) must be equal to or less that 40

Therefore 10 + d ≤ 40
