Answer:

(a) Locker A has the better deal

Step-by-step explanation:

Given

A = \frac{\$28}{yd^2} -- monthly

B = \frac{\$1.43}{ft^2} --- weekly

1\ month = 4\ weeks

Required:

Determine which gives the better price

B = \frac{\$1.43}{ft^2} --- weekly

Convert to monthly rate:

B = \frac{\$1.43*4}{ft^2}

B = \frac{\$5.72}{ft^2} --- monthly

Convert ft^2 to yd^2

1ft^2 = 0.111yd^2

So, we have:

B = \frac{\$5.72}{0.111yd^2}

B = \frac{\$51.53}{yd^2} --- monthly

By comparing:

A = \frac{\$28}{yd^2}

B = \frac{\$51.53}{yd^2}

Locker A has the better deal

Answer:

\boxed{ \ -  \frac{3}{45} }

Step-by-step explanation:

10 3/9 - 10 2/5

we need to convert mixed fractions to improper fractions

10 \frac{3}{9}  =  \frac{10 \times 9 + 3}{9}  =  \frac{93}{9}

10 \frac{2}{5}  =  \frac{10 \times 5 + 2}{5}  =  \frac{52}{5}

Now, we have 93/9 - 52/5

We need to equate the denominators, before subtracting them.

\frac{93}{9}  -  \frac{52}{5}  =  \frac{93 \times 5}{45}  -  \frac{52 \times 9}{45}

\frac{465}{45}  -  \frac{468}{45}

\frac{ - 3}{45}

\boxed{ -  \frac{3}{45} }

The result of 10 3/9- 10 2/5 is - 3/45

Point P is the center of the circle below. What is the exact area
Ber [7]

Answer:

192π unit²

Step-by-step explanation:

Given that :

Radius = 24

Area of circle = πr²

Area = π*24²

Area = 576π in²

The Shaded area is 120°

Entire Circumference = 360°

Hence, shaded area = 120°/ 360° = 1/ 3 of the area

1/3 * 576π in²

= 192π unit²
