Answer:

784m^2

Step-by-step explanation:

is a rectangle with sides of 40m and 20m, in the upper right corner a right triangle has been removed with the legs of: 40 - 32 = 8m and 20 - 16 = 4m, we find the area of the rectangle (b * h).

40 * 20 = 800m ^ 2, then we find the area of the right triangle

1/2 b * h: 1/2 8 * 4 = 16 m ^ 2.

we remove the area of the triangle from the rectangle and we have the area of the figure: 800 - 16 = 784m^2

Line BC has an equation of a line Y equals 2X +3 and F has an equation of a line Y equals -1/2 x+4 these two equations represent

Masja [62]

Answer:

Lines BC and F represent perpendicular lines

Step-by-step explanation:

we have

$y=2x+3$

the slope of the line BC is $m=2$

$y=-(1/2)x+4$

the slope of the line F is $m=-1/2$

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

$m1*m2=-1$

we have

$m1=2$ -----> slope line BC

$m2=-1/2$ -----> slope line F

Find the product of their slopes

$(2)(-1/2)=-1$

therefore

Lines BC and F represent perpendicular lines

four apples and one banana cost £1.40 seven apples and one banana cost £2.00 work out the cost of an apple and the cost of a ban

beks73 [17]

Answer:

apple: £0.20
banana: £0.60

Step-by-step explanation:

Let "a" and "b" represent the costs of one apple and one banana, respectively. Then the purchases can be written ...

4a +b = 1.40

7a +b = 2.00

Subtracting the first equation from the second gives ...

(7a +b) -(4a +b) = (2.00) -(1.40)

3a = 0.60 . . . . simplify

a = 0.20 . . . . . .divide by 3

Using this in the first equation, we have ...

4(0.20) +b = 1.40

b = 0.60 . . . . . subtract 0.80

The cost of an apple is £0.20; the cost of a banana is £0.60.
