A man has a 10m X 10m square garden. In the center is a 2m X 2m square patch which he cannot use. He divides his usable space in
ra1l [238]

Answer:

4m X 6m

Step-by-step explanation:

This is because if there is a 2m square in the middle, there is 8 m of usable space left along both sides of the garden.

Because the 2m square was in the middle, there is 8/2 = 4m along each width of the 4 small rectangles.

Becuase 4m is the width, there is 10 - 4 = 6m along each rectangle's length.

Charlotte’s weekly paycheck is based on the number of hours worked during the week and on the weekend. If she works 13 hours dur
Schach [20]
X: earn per  hour during the week
y: earn per hour during the weekend

13x + 14y = 250.90
15x + 8y = 204.70

Multiply the first equation by 4 and the second equation by 7

52x + 56y = 1003.6
105x + 56y = 1432.90

Subtract the first equation from the second:

 53x = 429.30

x = 429.30/ 53
x = 8.10

Solve any of the equation for y:

15x + 8y = 204.70

y = [204.70 - 15(8.10)]/8 = 10.40

y - x = 10.40 -8.10 = 2.30

Answer: she earns $2.30 per hour more during the weekend than during the week.

We want to find a fraction that is between

\frac{1}{4}\:and\:\frac{1}{2}

There are several ways to go about this.

There are also infinitely many fractions that can be found between the given fractions.

Let us go for the one in the middle of the two fractions.

So we add the two fractions and divide by 2.

a) \frac{\frac{1}{4} +\frac{1}{2} }{2}

Find LCM for the numerator

\frac{\frac{1+2}{4}}{2}

Simplify:

\frac{\frac{3}{4}}{2}

\frac{\frac{3}{2}}{2}

\frac{3}{8}}

b) \frac{\frac{1}{3} +\frac{3}{4} }{2}=\frac{13}{24}

c)\frac{\frac{1}{2} +\frac{3}{4} }{2}=\frac{5}{8}

d)\frac{\frac{3}{5} +\frac{7}{8} }{2}=\frac{59}{80}
