The product of 13 and m plus the product of 2.7 and n

Answers

Answer:

13 m + 2.7 n.

Step-by-step explanation:

Given  : the product of 13 and m plus the product of 2.7 and n

To find : Write expression .

Solution : We have given

Product of 13 and m = 13 * m

Product of 2.7 and n = 2.7 * n

According to question :

Sum of Product of 13 and m and Product of 2.7 and n

13 *m + 2.7 *n

13 m + 2.7 n.

Therefore, 13 m + 2.7 n.
13m+2.7n

Suppose the circumference of a circle is 8π. What is its area?

Answers

Circumference = (π) x (diameter)
Circumference = 8π
(π) x (diameter) = 8π
Diameter = 8
Radius = 4

Area = π x (Radius)²
Area = π x (4)²
Area = π x (16) = 50.27 units² (rounded)
Well, its diameter would be 8, making its radius 4. The formula for finding the area of a circle is π x radius^2. So, the area would be ^2.

Describe the multiplication pattern and find the next two terms. 25; 100; 400; 1600; 6400; . . .

A.The first term is 25. Each term is multiplied by 5. The next 2 terms are 32,000 and 160,000.

B.The first term is 25. Each term is multiplied by 4.
The next 2 terms are 25,600 and 102,400.

C.The first term is 25. Each term is multiplied by 4.
The next 2 terms are 2560 and 10,240.

D.The first term is 25. Each term is multiplied by 5.
The next 2 terms are 3200 and 16,000.

Answers

Answer is B

25 × 4 = 100
100 × 4 = 400
400 × 4 = 1600
1600 × 4 = 6400
6400 × 4 = 25600
25600 × 4 = 102400

How do you write 72.5% as a fraction in simplest form

Answers

The 72.5% as a fraction in simplest form is (29/40)

What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We have to write 72.5% as a fraction in simplest form.

So we put 72.5 over 100

That is (72.5/100)

Now multiply the top and the bottom by 10 to get rid of the decimal, giving;

725/1000

Then divide the top and bottom by like factors,

5 (145/200)

Then another 5,

29 over 40 (29/40)

Hence, the 72.5% as a fraction in simplest form is (29/40)

So you put 72.5 over 100 (72.5/100)
Then you multiply the top and the bottom by 10 to get rid of the decimal, giving you 725/1000
Then you divide the top and bottom by like factors, starting with 5 (145/200)
Then another 5, giving you 29 over 40 (29/40)

Which is longer ; 180 seconds or 3 minutes?

Answers

Both 180 seconds or 3 minutes are equal.

What is division?

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

We have two times,

180 seconds and 3 minutes.

180 seconds in minutes,

= 180/60

= 3 minutes.

Therefore, both are the same.

how you find the answer is you divide 60 into 180 and you get 3 which means 3 minutes so their both the same 

A stadium has 55,000 seats. Seats sell for ​$28 in Section​ A, ​$16 in Section​ B, and ​$12 in Section C. The number of seats in Section A equals the total number of seats in Sections B and C. Suppose the stadium takes in ​$1,158,000 from each​ sold-out event. How many seats does each section​ hold?

Answers

A=number of seats in section A
B=number of seats in section B
C=number of seats in section C

We can suggest this system of equations:

A+B+C=55,000
A=B+C                                      ⇒A-B-C=0
28A+16B+12C=1,158,000

We solve this system of equations by Gauss Method.

1             1              1               55,000
1            -1            -1                         0
28         16           12          1,158,000 


1             1              1               55,000
0            -2             -2             -55,000                                    (R₂-R₁)
0           12             16           382,000                                    (28R₁-R₂) 


1            1                1              55,000
0           -2              -2             -55,000
0            0                4               52,000                                     (6R₂+R₃)

Therefore:

4C=52,000
C=52,000/4
C=13,000


-2B-2(13,000)=-55,000
-2B-26,000=-55,000
-2B=-55,000+26,000
-2B=-29,000
B=-29,000 / -2
B=14,500.

A + 14,500+13,000=55,000
A+27,500=55,000
A=55,000-27,500
A=27,500.

Answer: there are 27,500 seats in section A, 14,500 seats in section B and 13,000 seats in section C.
