Yes, the answer would only be no if they gave you the area of both and there not the same. But the answer is Yes

Let one rectangle A has dimensions 12 cm by 8 cm

Area of the rectangle A = l *w

Area of the rectangle A = 12 * 8 = 96 sq.cm

If we shade 1/2 of area of rectangle A Then area of shaded region = 96/2 = 48 sq.cm

Let one rectangle B has dimensions 8 cm by 6 cm

Area of the rectangle A = l *w

Area of the rectangle A = 8 * 6 = 48 sq.cm

If we shade 1/2 of area of rectangle A Then area of shaded region = 48/2 = 24 sq.cm

So if the dimensions of two rectangles are different then the half of each rectangle will be different.

The answer for 10 2/3×31/8 rounded to the nearest whole number?
BigorU [14]
10 \frac{2}{3} ( \frac{31}{8}) can be changed into this equation:

\frac{32}{3}( \frac{31}{8}  )

The 32 and 8 have a common factor of 8 and can be simplified to become this equation:

\frac{4}{3} ( \frac{31}{1})

Now multiply across to get \frac{124}{3} which then simplifies to 41 \frac{1}{3} which as a decimal is 41.333 (repeating 3s). Nearest whole number is 41. 

Your answer is 41

If (x,y) is a solution to the system of equations shown below, what is the product of the y-coordinates of the solutions? x^2+4y
aliina [53]

Answer:

The product of the y-coordinates of the solutions is equal to 3

Step-by-step explanation:

we have

x^{2}+4y^{2}=40 -----> equation A

x+2y=8 ------> equation B

Solve by graphing

Remember that the solutions of the system of equations are the intersection point both graphs

using a graphing tool

The solutions are the points (2,3) and (6,1)

see the attached figure

The y-coordinates of the solutions are 3 and 1

therefore

The product of the y-coordinates of the solutions is equal to

(3)(1)=3

If the sum of a number and seven is tripled, the result is three less than twice the number. Find the number
hram777 [196]

Answer:

x = -24

Step-by-step explanation:

3(x + 7) = 2x - 3

3 * x = 3x

3 * 7 = 21

3x + 21 = 2x - 3

-21            -21

3x = 2x -24

-2x   -2x

x = -24

John bought a used truck for $4,500. He made an agreement with the dealer to put $1,500 down and make payments of $350 for the n
lbvjy [14]
<span>The extra cost can be calculated by working out the total he has spent and subtracting the value of the truck. He spends $1500 on a downpayment and (350 x 10 = $3500) on monthly payments, giving him a total outlay of $5000. This means he overspent by $500. $500 interest was paid for 10 months, so at that same rate, $600 would have been paid for 12 months. $600 as a percentage of the cost of the truck minus the down payment ($3000) is 20%. </span>
