Answer:

D) 33 degrees

Step-by-step explanation:

All interior angles of a quadrilateral must equal 360 degrees.

We have 3/4 angles, so let's write an equation:

360=x+265+32+30

simplify

360=327+x

subtract 327 from both sides

33=x

So, D is the correct option.

Answer:

◘ 12 pears

◘ 3 pineapples

◘ 10 kiwis

Step-by-step explanation:

Let \(x\) be the number of pears bought.

Therefore:

• number of pears = \(x\)

• number of pineapples = \(x - 9\)

• number of kiwis = \(x - 2\)

We know that the total cost was $13.50.

This means if she bought \(x\) pears at $0.50 each, \((x - 9)\) pineapples at $1.50 each, and \((x -2)\) kiwis at $0.30 each, the total would be $13.50.

∴  \([x \times 0.50] + [(x-9) \times 1.5] + [(x-2) \times 0.3] = 13.50\)

Expanding and multiplying:

⇒ \(0.5 x + 1.5x - 13.5 + 0.3x - 0.6 = 13.5\)

Collect like terms:

⇒ \(2.3x -14.1 = 13.5\)

Solve for \(x\):

⇒ \(2.3x = 13.5 + 14.1\)

⇒ \(2.3 x = 27.6\)

⇒ \(x = 27.6 \div 2.3\)

⇒ \(x = \bf 12\)

Therefore, she bought:

• 12 pears

•  \(x - 9\) = 12 - 9 = 3 pineapples

• \(x - 2\) = 12 - 2 = 10 kiwis

Marita bought 12 pears, 3 pineapples and 10 kiwis.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

Let x the number of pears bought,

y the number of pineapples bought,

z the number of kiwis bought,

Given that, Marita bought 9 more pears than pineapples and 2 fewer kiwis than pears,

y + 9 = x

y = x -9 and

z + 2 = x

z = x - 2

We know that the total cost was $13.50.

This means if she bought  pears at $0.50 each,  pineapples at $1.50 each, and  kiwis at $0.30 each, the total would be $13.50.

∴  0.50x + 1.50y+ 0.30z = 13.50

Substitute the values of y and z in equation,

⇒ 0.50x + 1.50(x -9)+ 0.30(x - 2) = 13.50

Expanding and multiplying terms in equation,

⇒  0.50x + 1.50x -13.50+ 0.30x - 0.60 = 13.50

Rearrange the like terms and apply the arithmetic operation

⇒ 2.3x - 14.1 = 13.50

⇒ 2.3x = 13.50 + 14.1

⇒ 2.3x = 27.6

⇒ x = 27.6/2.3

⇒ x = 12

Therefore, the number of pears bought = 12

So, the number of pineapples bought = 12 - 9 = 3

And the number of kiwis bought = = 12 - 2 = 10

Hence, Marita bought 12 pears, 3 pineapples and 10 kiwis.

Answer:

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

The least common multiple (LCM) of 6 and 9 is 18. so, the correct answer is B. 18.

To find the least common multiple (LCM) of 6 and 9, we can list their multiples and look for the smallest common multiple.

The first 5 multiples of 6 are

6, 12, 18, 24, 30.

The first 5 multiples of 9 are

9, 18, 27, 36, 45.

From these lists, we can see that the smallest common multiple of 6 and 9 is 18.

Therefore, the correct answer is B. 18.

∑ Hey, js1012201 ⊃

Answer:

(A) 4 = 10 - n

(B) 3 = n/2

(D) 8n = 48

Step-by-step explanation:

Given:

Select all the equations where n = 6 is a solution.

Choose 3 answers:
(A) 4 = 10 - n

(B) 3 = n/2

(C) 12 = n + 7

(D) 8n = 48

(E) 5 + n = 8

Solution:

Let's solve each answer choices to see where n = 6 is a solution:

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

(A) 4 = 10 - n

4 + n = 10 - n + n

4 + n = 10

4 + n -4 = 10 - 4

n = 6

(A) n = 6

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

(B) 3 = n/2

Multiply both sides by 2

2n/2 = 3 × 2

n = 6

(B) n = 6

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

(C) 12 = n + 7

Subtract both sides by 7

n + 7 -7 = 12 - 7

n = 5

(C) n = 5

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

(D) 8n = 48

Divide both sides by 8

8n/8 = 48/8

n = 6

(D) n = 6

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

(E) 5 + n = 8

Subtract 5 from both sides

5 - 5 + n = 8 - 5

n = 3

(E) n = 3

Answer:

C=48ft

I did 8*9 to get the full area, then subtracted it from the empty space area to get 48.

Answer:

48 ft^2

Step-by-step explanation:

split the figure and form two rectangles

for first rectangle

length = 8

breadth = 3

area of rectangle = l*b

=8*3

=24 ft^2

for second rectangle

length = 6 ft

breadth = 4 ft

area of rectangle = l*b

=6*4

=24 ft^2

area of the given figure = area of first rectangle + area of second rectangle

=24 ft^2 + 24 ft^2

=48 ft^2

split the figure as shown below .

check the image.

To solve this equation, you must multiply by a denominator and then subtract to isolate a variable.

Multiply by 4 on both sides of the equation.

\(\displaystyle 4(5 + \frac{k}{4}) = 4(3)\)

\(\displaystyle 20 + k = 12\)

Subtract 20 from both sides to isolate the k.

\(20 - 20 + k = 12 - 20\)

\(\boxed{k = -8}\)

The final answer is k = -8.

Answer:

Kevin is 7 years old right now.

Step-by-step explanation:

Let x be Kevin's age right now, that's what we're trying to find.

In 56 years, he'll be 9 times older than he is now, so we can say:

x + 56 = 9x

Now we can get the x values on the right side of the equation so that:

56 = 8x

Now solve for x and you have his current age which is 7.
