The relationship between men's whole-number shoe sizes and foot lengths is an arithmetic sequence, where a, is the footlength in inches that corresponds to a shoe size of n. A men's size 9 fits a foot 10.31 inches long, and a men's size 13 fits a
foot 11.71 inches long. What is the explicit formula for the arithmetic sequence? Round to the nearest hundredth, if necessary.
0 6, 7,514 0 35(n-1)
O a. - 9-0 35(n-1)
O a-9-286(n-1)
O a, - 10 31-2 86(n-1)

Answers

Answer 1
Answer:

Answer:

a =7.51+ 0.35(n - 1)

Step-by-step explanation:

The arithmetic sequence has the form:

a =a_1 + d(n - 1)

When a=10.31, n=9, we substitute to get:

a_1 + 8d = 10.31....eqn1

Similarly, when n=13 and a=11.71, we get:

a_1 + 12d= 11.71....eqn2

Subtract equation 1 from equation 2 to get:

4d = 1.4

This implies that

d = 0.35

Substitute into the second equation to get:

a_1 +12(0.35) = 11.71

Solve to get

a_1 = 7.51

Hence the explicit formula is:

a =7.51+ 0.35(n - 1)

Help right away what is 136 divided by 4 in long division

Answers

The quotient is 34 and the remainder is 0.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the liketerms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

136 ÷ 4

Using longdivision,

4 ) 136 (34

    12

      16

      16

        0

Thus,

The quotient is 34 and the remainder is 0.

zoey made 5 1/2 cups of trail mix for a camping trip. she wants to divide the trail mix into 3/4 cup servings. ten people are going on the camping trip, cam zoey make enough 3/4 cup servings so that each person on the trip has one serving. plz i need these answers asap on the pic. # 13, a., b., and c.

Answers

a.) Number of 3/4 cup servings in 5 1/2 cups = 5 1/2 / 3/4 = 11/2 / 3/4 = 11/2 x 4/3 = 44/6 = 7 1/3
Therefore, Zoey did not make enough 3/4 cup serving to go round everybody.

b.) For, every one to have a serving, we have 5 1/2 cups which we want to go round ten people, so each person should get 5 1/2 / 10 = 11/2 / 10 = 11/2 x 1/10 = 11/20.
So the serving should be 11/20 cup for every one to get serving.

c.) If she uses the 3/4 cup serving, then she will need 3/4 x 10 = 30/4 = 7 1/2 cups altogether.
Therefore, she will need to make extra 7 1/2 - 5 1/2 = 2 cups of trail mix.
10 * 3/4 = 30/4 = 15/2 = 7 1/2
7 1/2 > 5 1/2
a ) Zoey can`t make enough 3/4 cup servings.
b ) 5 1/2 : 10 = 11/2 : 10 = 11/2 * 1/10 = 11/20 cup servings
c ) She 
will need 7 1/2 - 5 1/2 = 2 cups of trail mix more.
