Answer:

-3n + 18

Step-by-step explanation:

an = dn + (a - d)

The difference is -3.

The first term is 15.

an = -3n + (15- (-3))

an = -3n + 15 + 3

an = -3n + 18

Answer:

aₙ= 18 -3n

Step-by-step explanation:

15, 12, 9, 6

Given AP with first term= 15 and common difference= -3

aₙ=a₁+(n-1)d= 15+(n-1)*(-3)= 15 - 3n+3= 18-3n

aₙ= 18 -3n

Convert 72° 36' 45" into centesimal measurement.

zavuch27 [327]

Answer:

Answer:

Step-by-step explanation:

x= centesimal angle (100 degrees in a

right angle)

y= sexagesimal angle (90 degrees in a

right angle)

x - y = 15

xx90/100 = y

xx9/10 = y

X - XX9/10 = 15

10x/10 - 9x/10 = 15

X/10 = 15

x= 150

y = 150x9/10 = 15x9 = 135

using centesimal system:

the sum of all external angles in a

polygon is 400 degrees (a full circle).

one external angle is the complement

of one internal angle to 200 degrees =

200-150=50 degrees.

to find the number of sides of the

polygon we need to find the number of

angles or corners. and that is how many

external angles fit into the full circle.

n = 400/50 = 8

the polygon has 8 sides

(4xy+x^2y+4)(xy+y^2)

marysya [2.9K]

If I read this right, the answer should be $x^{2y+4}y^{2}+x^{2y+5}y+4x^{2}y^{2}+4xy^{3}$ .

Hope that helped!!

The ratio of green pepper plants to red pepper plants in joes garden is 2 to 7 if joe has 20 more red peppers plants than green

PSYCHO15rus [73]

Let the number of red and green peppers be x and y respectively.

$x = y + 20$
$\frac{x}{y} = \frac{7}{2} \\ x = \frac{7}{2} y$
$\frac{7}{2}y = y + 20 \\ \frac{5}{2} y = 20 \\ y = 8$
$x = \frac{7}{2} y \\ x = \frac{7}{2} (8) \\ x = 28$

A bank teller assisted two customers with transactions. One customer made a $25 withdrawal from a savings account. The other cus

Rzqust [24]

Answer:

The withdrawal of $25 involved more money.

Step-by-step explanation:

We have been given that one customer made a $25 withdrawal from a savings account. The other customer made a $15 deposit.

We know that withdrawal stands for negative number, so withdrawal of $25 would be $-25$

The absolute value of $-25$ would be $|-25|=25$ .

We know that deposit stands for positive number, so deposit of $15 would be $15$ .

The absolute value of $15$ would be $|15|=15$ .

Since the absolute value of withdrawal is more than deposit, therefore, withdrawal involved more money.
