Find a 12 in the sequence -1, -3, -9, -27, ...

Answer:

7/3

Step-by-step explanation:

Since you have seven donuts to share with three brothers, you can calculate that each one of you will get 2 donuts and there will be a spare one left. You know that you also have to share that one so you split it into thirds. 7/3 = 2 1/3

Hope I helped!

B is correct...

Answer:

44.68 m²

Step-by-step explanation:

Area of a sector = θ/360*πr²

Where,

θ = 80°

r = 8 m

Plug in the values into the equation

Area of the sector = 80/360*π*8²

= 44.6804288 ≈ 44.68 m² (nearest hundredth)

try posting this same question just zoomed in a bit more :)

Answer:

multiply 36 by .20 and subtract that from 36

Step-by-step explanation:

20% is the amount off. if you multiply .20 and subtract it you'll get $7.20 so 36-7.20 which is $28.80.

Answer:

28.80 is 36 dollars 20 percent off.

Step-by-step explanation:

take the original price

divide the original price by 5

alternatively, divide the original price by 100 and multiply it by 20

subtract this new number from the original one

the number you calculated is the discounted value.

more simple steps:

1. subtract the final price from the original price

2. divide this number by the original price

3. multiply the result by 100

other explanation: a 20 percent discount is 0.20 in decimal format. secondly, multiply the decimal discount by the price of the item to determine the savings in dollars. for example: if the original price of the item equals 24$, y I u would multiply 0.2 by 24$ to GET $4.80

hope this helps!

Answer:

<J, <k, <L

Step-by-step explanation:

Automatically we know that L is the largest because it is a right triangle making it 90 degrees. Next we know J is the smallest because looking at the opposite side the 13 is the shortest side making that the smallest angle putting K in the middle.

Answer:

√729=√27*27=√27^2=27

Answer:

[tex] 3 \sqrt{3} [/tex]

Step-by-step explanation:

[tex]tan \: 60 \degree = \frac{y}{3} \\ \\ y = 3tan \: 60 \degree \\ \\ y = 3 \sqrt{3} [/tex]

Answer:

y = 3[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the tangent ratio in the right triangle and the exact value

tan30° = [tex]\frac{1}{\sqrt{3} }[/tex]  , then

tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{3}{y}[/tex] = [tex]\frac{1}{\sqrt{3} }[/tex] ( cross- multiply )

y = 3[tex]\sqrt{3}[/tex]

Answer:

A) 15

Step-by-step explanation:

20 x 0.75= 15

Answer: See explanation

Step-by-step explanation:

The value of the digit 3 in the number 63,297 is 3,000 while the value of the digit 3 in the number 60,325 is 300.

The difference between value of the digit 3 in the number 63,297 and the value of the digit 3 in the number 60,325 will be:

= 3000 - 300

= 2700

Answer:

$13,577.22

Step-by-step explanation:

Multiply 18,500 by 0.94 for each year

Answer:

Assume the number is X. What is given can be written as the following:

X < (1/4)*(8X+4)

Multiply 4 on both sides

4X< 8X+4

Subtract 4X+4 from both sides

-4 < 4X

-1<X i.e., X>-1 the number is greater than -1.

Answer:

k = ±[tex]\frac{10}{11}[/tex]

Step-by-step explanation:

121k² - 100 = 0

(11k + 10)(11k - 10) = 0

Answer:

(x-3)^2 + (y+2)^2 = 25

Step-by-step explanation:

Center is (3,-2) Radius is 5

3=h -2=k r=5

Formula (x-h)^2 + (y-k)^2 = r^2

Plug it in and switch the signs inside the ( )

(x-3)^2 + (y+2)^2 = 25

Answer:

The mean is 30

Answer:

4096pi/3

Step-by-step explanation:

Volume is pi * r^2 * h/ 3

r (radius) = 16

h (height)= 16

pi * 256 * 16/3 = 4096pi/3

Answer:

52.36 rounded to hundredth place

Step-by-step explanation:

8 is the height and radius is half of the diameter. Just plug those into the equation

Answer:

360:480

We know the total (840) so add the ratio: 3 + 4 =7

Divide 840 by 7 = 120

Multiply each part of the ratio by 120

3 x 120 = 360

4 x 120 = 480

Step-by-step explanation:

Answer:

A ratio of 1/2 can be entered into the equivalent ratio calculator as 1:2. 2/10 would be 2:10, 3/4 would be 3:4 and so on.

Answer:

234

Step-by-step explanation:

300 x .78 = 234

Answer:

234 pages.

Step-by-step explanation:

Remark

78% = 78/100

78% of 300 = 78/100 * 300 = 23400/100 = 234

Step-by-step explanation:

Answer:

x = 11

Step-by-step explanation:

x + 2(2x-2) = 51

x + 4x - 4 = 51

5x - 4 = 51

5x = 55

x = 11

Answer:

x = 11

Step-by-step explanation:

2x - 2 + 2x - 2 + x = 51

5x - 4 = 51

5x = 55

x = 11
