Answer:

Area is 72 in²

Step-by-step explanation:

= Area of three triangles + area of square.

[tex]{ \bf{ = 3 \times ( \frac{1}{2} b \times h) + (s \times s)}}[/tex]

substitute:

[tex]{ \sf{ = ( \frac{1}{2} \times 6 \times 6) + 2( \frac{1}{2} \times 6 \times 3) + (6 \times 6)}} \\ = { \sf{18 + 18 + 36}} \\ = { \sf{ {72 \: in}^{2} }}[/tex]

Answer:

(x+6)(x+6)

Step-by-step explanation:

x^2 + 12x + 36

Factor

What two numbers multiply to 36 and add to 12

6*6 = 36

6+6 =12

(x+6)(x+6)

Answer:

D. 20

Step-by-step explanation:

since the given shape is a parallelogram the parallel sides' length must be equal:

2x-10 = x+30

2x-x = 30+10

x = 40

2y-10 = y+10

2y-y = 10+10

y = 20

since z = x - y

z = 40-20

z = 20

compute the range of the figures into the table

Answer:

answer is [tex]\frac{23}{63}[/tex]

Step-by-step explanation:

the equation is

[tex]\frac{5}{63}-(-\frac{6}{21} )[/tex]

=> [tex]\frac{5}{63}+\frac{6}{21}[/tex]

=> [tex]\frac{5}{63}+\frac{2}{7}[/tex] ;(divide numerator and denominator of [tex]\frac{6}{21}[/tex] by 3)

=> [tex]\frac{5+2*9}{63}[/tex]

=> [tex]\frac{23}{63}[/tex]

Answer:

4.73 - 0.35 = 4.38. Mrs Applebaum needs to pay $4.38

Step-by-step explanation:

Answer:

$4.38

Step-by-step explanation:

$4.73 is the full price. She has a coupon for 35 cents OFF which means you have to subtract .35 from 4.73. 4.73 - .35 = 4.38

Answer:

224 more flowers

Step-by-step explanation:

If the planner wants the ratio of flowers to shrubs to be 12:1, that means there will be 12 times as many flowers as shrubs.

Find what 12 times the number of shrubs is:

24(12)

= 288

So, the planner will need 288 flowers in total.

Find how many more he needs to plant by subtracting the current amount of flowers from 288:

288 - 64

= 224

So, the garden planner will need 224 more flowers.

Answer:  r = C/(2pi)

This is the same as writing [tex]r = \frac{C}{2\pi}[/tex]

=========================================================

Explanation:

pi is some number (approximately 3.14) which means 2pi is also some number (roughly 6.28)

Saying c = 2pi*r means we have 2pi times r, and the result is the circumference c. To isolate r, we'll undo the multiplication. We'll undo it by dividing both sides by 2pi like so

C = 2pi*r

C/(2pi) = r

r = C/(2pi)

in which we can write it like [tex]r = \frac{C}{2\pi}[/tex]

So whatever C is, we divide it over 2pi (aka roughly 6.28) to get the radius.

-----------------

Extra Info (Optional Section):

As an example, let's say the circumference of the circle is 628 feet. This means the distance around the circle is 628 feet. So C = 628 would lead to...

r = C/(2pi)

r = C/(6.28)

r = 628/(6.28)

r = 100

So the radius would be roughly 100 feet.

Answer:

-2.

Step-by-step explanation:

Average rate of change of the function = [ f(-1) - f(-11)] / [(-1 - (-11)]

= [(-1)^2 + 10*-1 + 18 - ((-11)^2 + 10*-11 + 18)] / 10

= (1 - 10 + 18 - (121 - 110 + 18) / 10

= (9 - (29) /10

= -20/10

= -2.

Step-by-step explanation:

The answer is +2 or 2.

Answer:

The amount of balls on each side would stay the same. The amount of balls would stay the same as long as both sides are throwing the same number of balls at the same time.

Step-by-step explanation:

Equation for east side: 20 (balls) -1 (thrown over to west) + 1 (thrown over from west) = 20 balls

Equation for west side: 40 (balls) -1 (thrown over to east side) +1 (thrown over by east side) = 40 balls

Answer:

1) 11

2) -8

3) 30

15) 80x - 128

16) 138y

Step-by-step explanation:

For these problems, you will need to use either PEMDAS or distributive property.

PEMDAS stands for parentheses, exponents, multiplication/division, addition/subtraction. Problems must be solved by going in order of the acronym, always starting with anything in parentheses first.

Example of PEMDAS:

2) 8(-3 + 2)

Solve for what's inside the parentheses first. There are no exponents, multiplication, or division within the parentheses so next would be addition and subtraction.

-3 + 2 = -1 so the problem will now look like:

8 (-1)

Next, PEMDAS says to look for exponents. There are none. Multiplication and division are next. 8 is being multiplied by -1 so lets try that:

8 × -1 = -8

-8

Distributive property is when you take the number being multiplied on the outside of the parentheses and multiply it to each individual number within the parentheses.

Example of distributive property:

2) 8(-3 + 2)

Multiply the number on the outside of the parentheses, 8, to each number within the parentheses, -3 and 2:

8 × -3 and 8 × 2

The problem should look like:

-24 + 16

Then solve:

-8

Use whichever method you are most comfortable with as both will produce the same answer. I will solve the first few and the last few to help you.

1)

11(5) - 11(4)

55 - 44

11

3)

6(9) - 4(6)

54 - 24

30

15) *You must use distributive property for these last problems as you cannot add or subtract numbers and variables*

16(5x - 8)

80x - 128

*You can only combine like terms so this is fully simplified*

16)

23y(2 + 4)

46y + 92y

138y

Answer:

n=4

Step-by-step explanation:

Let's get rid of the parenthesis first. We're left with -170=-56n+49+5. Let's move all of the numbers together so that the variable is separated from the numbers. Now we have 56n=224 using inverse operations. If we divide both sides by 56, we're left with n=4.

Hope this helped!

Answer:

n = 4

Step-by-step explanation:

-170=-7(8n-7) +5

-170=-56n+49+5

-170=-56n+54

-170+56n=54

56n=170+54

56n= 224

n=4

Answer: x + 2x - 3 = 42 is the equation and kara is 15 years old and cassies is 27 years old.

Step-by-step explanation:

Let age of kara be x years

Cassie's age will be 2x-3 years

ATQ

x + 2x-3 = 42

3x = 42+3

3x = 45

x = 45/3

x = 15

Kara's age = 15 years

Cassie's age = (15×2)-3

= 30-3

= 27 years

Answer:

?

Step-by-step explanation:

Brainly challenge.

Answer:

Half-Sphere Volume = [( π •diam³) / 6] / 2

Cylinder Volume =   ¼ • π • diam² • height

Cylinder height = 19 meters

Sphere diameter = 10 meters

Cylinder portion = ¼ • π • diam² • height

Cylinder portion volume = ¼ • π • 10² • 19

Cylinder portion volume = 1,492.26

Half-Sphere Volume = [( PI * 10^3) /6 ] / 2

Half-Sphere Volume = 261.80

Total Volume = 1,492.26 + 261.80 = 1,754.06 cubic meters

corn is $1.13 per cubic meter

total cost = 1,754.06 * $1.13 = 1,982.08

Answer is C 1,981.08

Answer:

x =56

Step-by-step explanation:

1/4 x - 1 =13

Add 1 to each side

1/4x - 1+1 = 13+1

1/4 x = 14

Multiply each side by 4

1/4x * 4 = 14*4

x =56

Answer:

Rs 2160

Step-by-step explanation:

1 dozen = 12 copies

2 dozen = 24 copies ( 2*12)

72÷12 = 6 dozen

72 copies = 6 dozen

1 dozen = Rs 720÷2

1 dozen Rs 360

6 dozen = 360*6

6 dozen = 72 copies = Rs 2160

h = 6 and j = 4

( 6 + 6² - 4 ) ÷ 2

Evaluate using PEMDAS

Parenthesis

Exponents

Multiplication and Division (left to right)

Addition and Subtraction (left to right)

First do operations inside of the parenthesis

( 6 + 6² - 4 ) ÷ 2

Exponents come first

(6 + 36 - 4) ÷ 2

Then do addition and subtraction going left to right

(6 + 36 - 4) ÷ 2

Add 6 and 36

( 42 - 4 ) ÷ 2

Subtract 42 and 4

38 ÷ 2

Finally do the division

Answer:

The answer is 782

Step-by-step explanation:

8 to the 3rd power would be 512

And if you add 270 + 512

270 + 512 = 782

Answer:

782

Step-by-step explanation:

8^3 +270

Calculate 8 to the power of three : 8 x 8 x 8 = 512

Then add 512 to 270

512+270 = 782

Answer:

Nicole should take 13 1/8 cups of snack mix.

Step-by-step explanation:

If a serving size is 7/8 and Nicole wants to take 15 serving sizes (15 7/8's), then we must multiply 7/8 by 15:

15 × 7/8

Write 15 over 1 (15 = 15/1) to make the calculations easier:

15/1 × 7/8

Multiply the numerators and denominators separately:

15 × 7 / 1 × 8

105 / 8

Instructions don't say you have to do this but I will convert this improper fraction into a mixed number:

105/8 = 13 1/8

Answer:

Area of a complete circle = PI * r^2

The shaded area is 1/3 of the circle so

Area = (PI * 9^2) / 3

Area = (254.4690049408) / 3

Area = 84.8230016469

Area = 84.82 square feet (rounded)
