Jerome wants to buy grass seed to cover his whole lawn, except for the pool. The pool is 7 1/2 m by 3 1/4 m. Find the area the grass seed needs to cover.

Answers

Answer:

24 [tex]\frac {3} {8}[/tex] m

Step-by-step explanation:

[tex]\frac{15}{2}[/tex]×[tex]\frac{13}{4}[/tex]

[tex]\frac{15x13}{2x4}[/tex]

Simplify

[tex]\frac{195}{8}[/tex]

Answer: 24 [tex]\frac{3}{8}[/tex] m

The area of the grass seed Jerome needs to cover is A = 34.375 m²

What is the Area of a Rectangle?

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the grass seed needs to cover be A

Now , the area of the lawn L = ( 11 3/4 ) x 5 m²

The area of the lawn L = 58.75 m²

where the length of the pool l= ( 7 1/2 ) m = 7.5 m

The width of the pool is w = ( 3 1/4 ) m = 3.25 m

Now , Area of Rectangle = Length x Width

On simplifying , we get

Area of the pool P = 7.5 x 3.25 = 24.375 m²

Now , the area of the grass seed needs to cover A = L - P

The area of the grass seed needs to cover A = 58.75 m² - 24.375 m²

The area of the grass seed needs to cover A = 34.375 m²

Therefore , the value of A is 34.375 m²

Hence , the area of the grass seed is 34.375 m²

Answer:

[tex]y' = 5x + 4[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \frac{1}{5}x - \frac{4}{5}[/tex]

Required

The inverse relation

[tex]f(x) = \frac{1}{5}x - \frac{4}{5}[/tex]

Rewrite as:

A. (4, 11π/6)
B. (4, 5π/3)
C. (2, 5π/3)
D. (2, 11π/6)

Answers

9514 1404 393

Answer:

  B.  (4, 5π/3)

Step-by-step explanation:

If you sketch the location of the point, you find the coordinates correspond to the side lengths of a 30°-60°-90° "special" triangle. The reference angle is 60°, or π/3 radians, and the magnitude of the vector is twice the short dimension, so is 2×2 = 4.

The polar coordinates are (4, 5π/3).

Answer:

Step-by-step explanation:

1 1/5 of 1 1/2 meters  

= (1+1/5) x (1+1/2)  

= 1x1 + 1x1/2 + 1x1/5 + 1/5*1/2  

= 1 + 1/2 + 1/5 + 1/10  

= 1 + (1x5+1x2+1)/10

1 1/5 of 1 1/2 meters  

= (1+1/5) x (1+1/2)  

= 1x1 + 1x1/2 + 1x1/5 + 1/5*1/2

A right rectangular container is 10 cm wide and 24 cm long and contains water to a depth of 7cm. A stone is placed in the water and the water rises 2.7 cm. Find the volume of the stone.

Answers

Answer:

648cm³

Step-by-step explanation:

The container is a cuboid thus:

volume of water is:

v=l×w×h

=10×24×7

=1680cm³

volume of water+stone=10×24×(7+2.7)

=10×24×9.7

=2328cm³

Thus volume of stone equals

2328-1680.

=648cm³
