Answer:

The common difference is $11$

Step-by-step explanation:

we know that

In an <u>Arithmetic Sequence</u> the difference between consecutive terms is a constant called the common difference

so

In this problem we have

$-15,-4,7,18,29,...$

Let

$a1=-15\ a2=-4\ a3=7\ a4=18\ a5=29$

Find the difference between consecutive terms

$a5-a4=29-18=11$

$a4-a3=18-7=11$

$a3-a2=7-(-4)=11$

$a2-a1=-4-(-15)=11$

therefore

The sequence is an Arithmetic Sequence

The common difference is $11$

90 percent as a fraction in simplest form

inysia [295]

Whenever a number is followed by percent, you can turn it into a fraction by simply moving the decimal places two places to the left:

90.0 % becomes .90

As a fraction, this is 90 over 100. To reduce it to its simplest form, divide by 10:

9/10

Evaluate.<br> 3/4<br> minus<br> 3/8<br> Divided by <br> 2/3

user100 [1]

Answer:

3/16 or 0.1875

Step-by-step explanation:

3/4 - ((3/8)/2/3))

= 3/4 - 3/8 * 3/2

= 3/4 - 9/16

= 12/16 - 9/16

= 3/16 or 0.1875

Hope this help you :3

Maya has 3 times as many dimes as nickels. She has 4 more quarters than nickels. if she has a total of $9.40, how many of each t

puteri [66]

Answer: nickels = 14, dimes = 42, quarters = 18

<u>Step-by-step explanation:</u>

Let n represent nickels <em>which has a value of $0.05 </em>

Let d represent dimes <em>which has a value of $0.10</em>

Let q represent quarters <em>which has a value of $0.25</em>

It is given that:

n = n

d = 3n

q = n + 4

and their total value is $9.40 ⇒ n + d + q = $9.40

Use substitution to find the quantity of nickels:

.05(n) + .10(3n) + .25(n + 4) = 9.40

5n + 10(3n) + 25(n+4) = 940 <em>multiplied by 100 </em>

5n + 30n + 25n + 100 = 940 <em>distributed</em>

60n + 100 = 940 <em>added like terms</em>

60n = 840 <em>subtracted 100</em>

n = 14 <em>divided by 60</em>

n = 14

d = 3n

= 3(14)

= 42

q = n + 4

= (14) + 4

= 18

Formulate the situation as a system of inequalities. (Let x represent the number of goats the farmer can raise and y represent t

Firdavs [7]

Answer: He can raise up to 40 goats and 100 llamas.

Step-by-step explanation:

Hi, to answer this question we have to write system of equations with the information given:

The space each goat needs (4) multiplied by the number of goats (x); plus The space each llama needs (10) multiplied by the number of llamas must be less or equal to the acre land available (800)

4x +10y ≤ 800 (acres)

The amount of veterinary care (in $) each goat needs (110) multiplied by the number of goats (x); plus The amount of veterinary care each llama needs (88) multiplied by the number of llamas (y)must be less or equal to the Rancher's budget.(14520)

110x +88y ≤ 14,520 (cost)

Multiplying the first equation by 27.5, and subtracting the second equation to the first one:

110x + 275y ≤22,000

-

110x +88y ≤ 14,520

____________

187y ≤ 7480

y ≤ 7480/187

y ≤ 40

Replacing y in the first equation

4x +10(40) ≤ 800

4x +400 ≤ 800

4x ≤ 800-400

4x ≤ 400

x ≤ 400/4

x ≤ 100
