Given an = 3n-5, what is the common difference?

Answers

Answer:

3

Step-by-step explanation:

A common difference is found in arithmetic sequences. The simplified formula for arithmetic sequences, which is what is used here, is [tex]a_{n}=dn-a_{0}[/tex]. Where d is the common difference and [tex]a_{0}[/tex] is the zeroth term. So, in the given equation 3 must be the common difference.

Answers

Answer:

3a

Step-by-step explanation:

the common factors are what make up the terms. 12a is divisible by 3a

9a^2 is divisible by 3a

12a/3a = 4

9a^2/3a

(9a × 9a) / 3a = (9a × 3)

The greatest factor of both 12a and 9a² is; C: 3a

What is the Greatest Common Factor?

We want to find the greatest common factor of 12a and 9a². Now, let us first list the factors of both expressions;

there are 45 students In a class. if 60% of them are girls. find the numbers of girls and boys​

Answers

Step-by-step explanation:

No. of students in class = 45 .

Percentage of girls = 60% .

No . of girls = 45 × 60/100 = 45 × 3/5 = 18 .

No. of boys = 45 - 18 = 27

Answer:

27 girls

18 boys

Step-by-step explanation:

Convert 60% to a decimal.

60% · .01 =  0.6

Multiply 45 students by 0.6 to find the number of girls in the class.

45 * 0.6 = 27 girls

Subtract this amount from the total number of students in the class.

45 - 27 = 18 boys

There are 27 girls and 18 boys in the class.

A cylindrical water towers has a diameter of 15 meters and a height of 5 meters. About how many gallons of water can the gallon contain?

Answers

Answer:

233445.54 gallons

Step-by-step explanation:

Given data

Diameter= 15m

Radius= 7.5m

Height= 5m

Let us first find the volume

the volume of a cylinder is given as

V= πr^2h

substitute

V= 3.142*7.5^2*5

V= 3.142*56.25*5

V=883.6875 m^3

Hence the volume in gallons is

233445.54 gallons  (from conversion tables)

whats the measure of angle E ?

Answers

Answer:

57degrees

Step-by-step explanation:

The triangle is an isosceles triangle, hence m<D = m<E (base angles are equal)

Taking the sum of the angles and equating to 180

5x-4 + 4x+1 + 4x+1 = 180

5x+4x+4x-4+1+1 = 180

13x - 2 = 180

13x = 180 + 2

13x = 182

x =182/13

x = 14

Get m<E

m<E = 4x+ 1

m<E = 4(14)+ 1

m<E = 56+1

m<E = 57degrees

Hence the measure of m<E is 57degrees
