For the sequence of numbers

Work out the position to term rule

22, 23, 24, 25, .......

Answers

Answer:

The term rule will be:

[tex]a_n=n+21[/tex]

Step-by-step explanation:

Given the sequence

[tex]22, 23, 24, 25, ...[/tex]

Computing the common difference of all the adjacent terms

[tex]22,\:23,\:24,\:25[/tex]

[tex]23-22=1,\:\quad \:24-23=1,\:\quad \:25-24=1[/tex]

As the difference between all the adjacent terms is the same and equal to

[tex]d=1[/tex]

The first element of the sequence

[tex]a_1=22[/tex]

We know that  An Arithmetic sequence has a constant difference 'd' and is defined by

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substituting [tex]a_1=22[/tex], and [tex]d=1[/tex] in the nth term to get the term rule

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=\left(n-1\right)+22[/tex]

[tex]a_n=n+21[/tex]

Therefore, the term rule will be:

[tex]a_n=n+21[/tex]

Marie uses 2.3 oz of nuts for each bag of trail mix she makes. She uses 27.6 oz of nuts in all.


How many bags of trail mix does Marie make?


Enter your answer in the box.

Answers

Marie makes 12 bags!
This is because she has 27.6 oz nuts, and if she uses 2.3oz for each bag that means we can divide it to get the answer. 27.6 divided by 2.3=12

the number of girls on the school's basketball team decreased by 20% this year. if there were 25 girls on the team last year. how many girls are on the team this year

Answers

Answer:

Step-by-step explanation:

okay so to get 10% of 20 you just move the decimal to the right one so 25.0 would become 2.5 then to find 20% of that you multiply by 2 so 2.5 x 2 = 5 so that means the team lost 5 girls. 25-5=20 therefor there are 20 players on the team this year

y= -2x-2

Step-by-step explanation:

y=mx + b

y=-2x -2

slope -2 (m=-2) thats your slope

Points are (-3,4) (1,-4)

y2 -y2   -4 - 4 = -8

x2 -x1     1 - -3 =  4

-8/4    simplify

-2/1  

   

Write the equation of the line that has y-intercept of 4 and goes through the points (0,4) & (2.0) (Hint: use those points
to calculate slope first and write answer using y = mx + b)

Answers

Answer:

y = -2x + 4

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of a line passing through (0, 4) and (2, 0) will be,

m = [tex]\frac{4-0}{0-2}[/tex]

   = -2

Y-intercept of the line 'b' = 4

Therefore, equation of the line will be,

y = -2x + 4

Toby skated from his house to the beach at a constant speed of 888 kilometers per hour, and then skated from the beach to the park at a constant speed of 777 kilometers per hour. The total distance Toby skated was 202020 kilometers, and it took him twice as long to get to the park. Let bbb be the number of hours it took Toby to skate from his house to the beach, and ppp the number of hours it took him to skate from the beach to the park. Which system of equations represents this situation?

Answers

Answer:

8b+7p=20

p = 2b

Step-by-step explanation:

Given that there is a constant speed of 8 km per hour and the number of hours be b so here 8b signifies the distance

Now on the other hand there is a constant speed of 7 km per hour and the number of hours be p so here 7p signfies the distance

So the total distance would be

= 8b + 7p

And, the total km is 20

Now the whole equation would be

8b + 7p = 20

Also it is mentoined that for getting into the park it is twice for getting into the beach

So, it would be

p = 2b

Therefore the system of equations are as follows

8b+7p=20

p = 2b

Your recipe must meet the following contest guidelines:1. It must have at least five different ingredients.2. The amount of each ingredient should be represented by a different mixed number.3. The recipe must make exactly 10 cups of trail mix.After you write your recipe, complete the following for your contest entry: Prove that your recipe makes exactly 10 cups. Explain the most efficient method for measuring each ingredient using onlythe following two measuring cups: 31 cup and 41 cup. You can use one or both of the measuring cups. Note: Depending on the fractions that you chosefor your ingredient amounts, it may not be possible to create each exact amount using only 13 and 14 measuring cups. If you need to, you can round your ingredient amounts using benchmarks and then explain how you would estimate that amount. For example, if you need 74 cup of an ingredient, 74cup is slightly more than 12 cup. You could fill up your 14 measuring cup twice to make 12 cup of that ingredient, and then add just a tiny bit more to estimate 74 cup.
