What is LCM?

It is defined as the common number of two integers, which is the lowest number that is a multiple of the two or more numbers. The full name of LCM is the least common multiple.

It is given that:

Two boats leave the jetty at the same time. one of them returns to the jetty every 25 minutes and the second one returns every 30 minutes.

Take the LCM of 25 and 30:

Using a tree diagram, the prime factors of 25 provide 52 and 30, which are 2 x 3 x 5. The result of multiplying all the factors together is 5 x 5 x 2 x 3 = 150.

Thus, the answer is after 150 mins or 2 hours and 30 minutes if two boats leave the jetty at the same time.

Answer:

150 mins or 2 hrs 30 mins

Step-by-step explanation:

This is simply the LCM ( lowest common multiple)

therefore, you find all the prime factors of 25 using a tree diagram resulting in 5^2 and 30 which will be 2 x 3 x 5. Then you multiply all the factors together and you will get 5 x 5 x 2 x 3 = 150

so....

the answer is after 150 mins

or 2 hours and 30 minutes

In the past, 25% of the town residents participated in the school board elections. The town officials recently undertook an extensive campaign to encourage registered voters to participate in the election process. They are interested in determining whether the promotional campaign actually increased the proportion of voters. The correct set of hypotheses is _____. a. H0: p < .25; Ha: p ≥ .25
b. H0: p ≥ .25; Ha: p < .25
c. H0: p > 25; Ha: p ≤ 25

Answers

Answer:

H0: p ≤.25 Ha: p >.25

Step-by-step explanation:

One choice is missing. Correct choices are:

a. H0: p > 25 Ha: p ≤ 25

b. H0: p ≥ .25 Ha: p .25

If the sample proportion is found significant under null hypothesis at a specified significance level, then null hypothesis can be rejected and can be concluded that there is significant evidence that the promotional campaign actually increased the proportion of voters.

2x +8y =20
-5x-20y=-50

Answers

System of Equations.
You can either substitute or eliminate a variable.

Substitue:
2x +8y =20
÷2 ÷2 ÷2
x +4y =10
x = -4y +10 (plug this into the second equation)
-5(-4y +10) -20y = -50 (distribute)
20y -50 -20y = -50
-50 = -50
0 = 0
Ax + by =12; 2x + 8y = 60. ax + by = 12; 2x + 8y = 60

The students at Midtown Middle school sold flowers as a fundraiser in September and October. In October, they charged $1.50 for each flower. The October price was a 20% increase of the September price. Part A What was the price of the flowers in September?
Enter your answer in the box.
$___


Part B
The seventh-grade class earned 40% of the selling price of each flower. In September, they sold 900 flowers. In October, they sold 700 flowers. Select a choice from each drop-down menu to make a true statement.

The seventh-grade class earned more money in ___ by ___

First Blank Choices: September, October
Second Blank Choices: $30, $75, $90

Answers

Part A) $1.25
Part B) September, $30

Explanation

Part A)
Let x be the amount the flowers sold for in September.  Since the October selling price is a 20% increase, this is 0.20x.  We add this to x, the price of September, since it is an increase:
x+0.2x

This is equal to October's selling price, 1.50:
x+0.2x = 1.50

Combine like terms:
1.20x = 1.50

Divide both sides by 1.20:
1.20x/1.20 = 1.50/1.20

x = 1.25

This means the flowers sold for $1.25 in September.

Part B)
We first find out how much money they collected from selling flowers in September.  The September selling price was $1.25, and they sold 900:
1.25(900) = 1125

They earn 40% of this:
0.40(1125) = $450

They earn $450 in September.

The October selling price was $1.50, and they sold 700 flowers:
1.50(700) = 1050

They earn 40% of this:
0.40(1050) = 420

They earn $420 in October.

This means they earn more money in September, and they earned 450-420 = $30 more.

Is it true that the order when dividing three real numbers does not affect the answer

Answers

let's take a peek if that's so.


27 ÷ 3  = 9

27 ÷ 3 ÷ 9 => 9 ÷ 9 = 1

let's now change the order

9 ÷ 3 ÷ 27

9 ÷ 3 = 3, so 9 ÷ 3 ÷ 27 is 3  ÷ 27 = 0.1111111111111....

low and behold, we changed them about, and notice the different quotient.

recall, by order of operations, divisions are done from left-to-right.

What is the missing number in the equation.. 35.4 x □ = 3.54. A. 100 B. 10 C. 1/10 D. 1/100

Answers

The correct answer is 1/10.
This equation can be solved using simple algebra.
Let's say that the missing is A, hence replacing the box with the A, giving:

35.4 x A = 3.54

We then could divide both sides of the equation- left hand side (35.4 x A) and the right hand side (3.54)- with 35.4, as we would want to get rid of this number from the left to leave us with A only. The equation then becomes:

A = (3.54/35.4)
Simply use the calculator and you'd get 1/10.
Which is C!
