Which mathematical statements are true?

Mathematics
1 answer:
Over [174]3 years ago
4 0

Answer:

1) If 3 is an odd number, then 3 times 3 is an even number.

False because multiplying odd number by an odd number also gives an odd number.

2) If 6 is less than 7, then 4 is greater than 7.

False because 4 is smaller than 6. As 6 is smaller than 7 then 4 must also be smaller.

3) Six is divisible by 3, and 10 is a multiple of 2.

True. 6/3 = 2 and 2 x 5 = 10. Both the conditions are true so it is also true.

4) The average of the data is greater than the largest value in the data, or it’s less than the largest value in the data.

True.

We have two conditions in this statement and an 'or' between them. One of the conditions is true that is "average is less than the largest value in the data". So the statement as a whole is true.

5) The slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value.

True.

6) If an equilateral triangle has equal angles, then all its angles will measure 45°.

False.

A triangle has 3 angles whose sum = 180 degrees.

For equilateral triangle each angle will measure 180/3= 60 degrees.

# 6 The capacity of a cylindrical fuel tank is 2.5 kl and its height 10 m. What is the area of its base?
Lina20 [59]
<h3>The area of base is 0.25 square meter</h3>

<em><u>Solution:</u></em>

Given that,

The capacity of a cylindrical fuel tank is 2.5 kl and its height 10 m

To find: area of base

<em><u>The volume of cylinder is given as:</u></em>

V = \pi r^2h

The area of base of cylinder is area of circle

Area\ of\ circle = \pi r^2

Therefore,

V = base\ area \times height

From given,

h = 10 m

v = 2.5 kl

1 kilo liter = 1 cubic meter

Therefore,

2.5 kl = 2.5 cubic meter

Substitute height = 10 and volume = 2.5

2.5 = base\ area \times 10\\\\ base\ area = \frac{2.5}{10}\\\\ base\ area = 0.25

Thus area of base is 0.25 square meter

A school bus has 25 seats, with 5 rows of 5 seats. 10 students from 2nd grade and 5 students from 1st grade travel on the bus. H
andre [41]

Answer:

(Answer in attachment, explanation below)

Step-by-step explanation:

The answer is B. 5P5 x 20P15.

This is because to make the second grade students to sit in the first row we have 5 seats and 5 students so we will permute the 5 students to those 5 seats. So 5P5.

Now we are left with 20 seats and 15 first grade students so we can simply permute those 15 students into those 20 seats. So 20P15.

Finally using the counting rule principle we will multiply both of these so 5P5 x 20P15.

No. of students from first grade = 15

No. of students from second grade = 5

There are 5 rows of seats

Each row contains 5 seats

Total seats = 25

No. of ways for second-grade students occupy the first row(i.e first 5 seats) =  

Remaining seats = 20

No. of students from first grade = 15

So, No. of ways for first-grade students occupy remaining seats =  

So,  No. of ways for the students can be seated if all of the second-grade students occupy the first row =  

So, Option B is true

Hence No. of ways for the students can be seated if all of the second-grade students occupy the first row is
