Answer:

Step-by-step explanation:

a) area of the rectangle = length × breadth

Therefore area should be = 12cm × 6cm

Which should give you the answer 72centimetre squared.

b) area of triangle A = 1/2 × b × h

So that is 1/2 × 3 × 6

Which is 18 centimetres × 1/2

Which is 9 centimetres squared

c) area of triangle B = 1/2 × b × h

So 1/2×3×6=18

Now 1/2×18 should give you 9 centimetres squared

d) therefore the area of the parallelogram = 72+9+9=90 centimetres squared

Therefore the area of the parallelogram is 90 centimetres squared

Which set of points is not coplanar?

spin [16.1K]

we know that

Coplanar points are three or more points which lie in the same plane. Remember that a plane is a flat surface which extends without end in all directions. Any three points in 3-dimensional space determine a plane.

case a) points A, B, E

Any group of three points determines a plane

so

The points A,B,E are coplanar

case b) points A, B,C,E

The four points do not belong to the same plane

so

The points A,B,C,E are not coplanar

case c) points B, C, D

Any group of three points determines a plane

so

The points B, C, D are coplanar

case d) points A,B, C, D

The base of the pyramid is a flat surface, the four points lie in the same plane

so

The points A,B, C, D are coplanar

therefore

the answer is the option

points A, B, C, E are not coplanar

Mo’s farm stand sold a total of 165 pounds of apples and peaches. She sold apples for $1.75 per pound and peaches for $2.50 per

9966 [12]

Answer: 65 pounds of Peaches were sold.

Step-by-step explanation:

Let the number of pounds of Peaches sold = X pounds

Therefore the pound of apple sold = (165 - X ) pounds

Total pounds of apple and peaches sold = 165 pounds

Sale made on Peaches at the cost of $2,50 per Peache = $2.50X

sale made on apple sold at the cost of $1.75 per apple = $1.75(165 - x )

Total sale made on the sale of both Peaches and apple = $337.50

Therefore , open the bracket, add everything together and equate to the total sale made which is $337.50

we now have

2.50x + 1.75( 165 - x ) = 337.50

2.50x + 1.75 x 165 - 1.75x = 337.50

2.50x + 288.75 - 1.75x = 337.50

collect like terms

2.50x - 1.75x = 337.50 - 288.75

0.75x = 48.75

divide through by the coefficient of x which is 0.75

x = 48.75/0.75

= 65pounds .

Therefore, Mo's farm sold 65 pounds of Peaches.

Check ;

65 x 2.50 = $162.5

subtract 65 from 165 to get the pound of the appel

165 - 65 = 100 pounds of apple was sold.

now multiply 100 x 1.75

= $175

Now add the two together to give the total sale ,

$162.5 + $175 = $337.50.
