Can someone help explain this to me?​

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.

This is an obtuse angle.

Answer:

i hope you understand this answer

[tex]3x : 8 = 9 : 2[/tex]

[tex] \frac{3x}{8} = \frac{9}{2} [/tex]

[tex]3x × 2 = 8 × 9[/tex]

[tex]3x = \frac{8 \times 9}{2} [/tex]

[tex]3x = 4 \times 9[/tex]

[tex]x = \frac{4 \times 9}{3} [/tex]

[tex]x = 4 \times 3[/tex]

[tex]x = 12[/tex]

Answer:

$50.50

Step-by-step explanation:

From the above question, we are to find the total cost of the tickets Mr Montes bought

An adult ticket to the school play cost $14.75.

A child ticket cost $5.25.

Mr. Montes bought 2 adult tickets and 4 child tickets.

Hence, the total cost is

= 2 × $14.75 + 4 × 5.25

= $29.5 + $21

= $50.50

Step-by-step explanation:

I think the answer is B

sorry if I am wrong

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.

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

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

There are 27 girls and 18 boys in the class.

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

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

Factors of  12a are; a, 1, 2, 3, 4, 6, 12, 1a, 2a, 3a, 4a, 6a, 12a

Factors of  9a² are; 1, 3, 9, 1a, 3a, 9a

The greatest factor that is common to both 12a and 9a² is 3a

Answer:

Percentage

Step-by-step explanation:

The higher the probability number or percentage of an event, the more likely is it that the event will occur. If an event has only one possible outcome, the probability for this outcome is always 1 (or 100 percent).

Answer:

It is the first answer

Step-by-step explanation:

Because you are multiplying which also means (product of something).

The x variable is for the number of books she buys to read so when x is 0!the cost would be what she paid for the reader.

The answer is B. The cost of the reader

Step-by-step explanation:

The width of the cylinder might also be the diameter of its circular faces, and half of the diameter is the radius. So, dividing the width by 2 might give you the radius.

[tex] \frac{19}{6} \pi \times \frac{360}{75} = \frac{19}{6} \pi \times \frac{24}{5} = \frac{76}{5} \pi[/tex]

Answer:

75%

Step-by-step explanation:

You pick a card at random. 6 7 8 9 What is P(not 9)? Write your answer as a percentage. %

Given the following

Total cards = 4 (6,7,8,9)

If the card is not 9, the required card will be (6,7,8)

Number of cards that are not 9 is 3

Probability = expected/total

Pr(not 9) = 3/4

express as percent

Pr(not 9) = 3/4×100

Pr(not 9) = 75%

Answer:

50%

Step-by-step explanation:

There are 4 cards, numbered 6, 7, 8, and 9. The numbers greater than 7 are 8 and 9. There are 2 numbers greater than 7.

P(greater than 7)  =  

2

4

Write your answer as a decimal. Then convert your answer to a percentage.

2

4

 =  0.5  =  50%

P(greater than 7) = 50%

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

basically 1 of 80 is 1.25 and multiply 1.25 times the money jaylon spent sorry i am really bad at explaining only good at solving

Answer:

34.5%

Step-by-step explanation:

to find the percent of money that was spent, you turn it into a fraction-

27.60/80

=0.345

then to get the percent you multiply-

0.345*100

=34.5%

good luck :)
