Answer:

7/20 of the lawn still needs to be mowed.

The son mowed most of the lawn 7/20 of the lawn still needs to be mowed.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

Mrs. jones mowed 2/5 of her lawn and her son mowed 1/4 of it.

Now, Size of the lawn mowed by Miss Jones = 1/4

And, Size of the lawn mowed by her son = 2/5

To know who mowed the most lawn, find the LCM of the denominators.

The LCM of 4 and 5 = 20

Make the denominators of both fractions to be 20

Hence, Size of the lawn mowed by Miss Jones = 1/4 x 5/5 = 5/20

And, Size of the lawn mowed by her son = 2/5 x 4/4 = 8/20

Since, 8/20 > 5/20, Miss Jones son mowed more part of the lawn than Miss Jones.

Hence, The part of the lawn still needs to be mowed is,

⇒ 1 - 1/4 - 2/5

⇒ 7/20

The area of a parallelogram can be found by finding the product of its height and base. The area of  the resulting figure is 105/4 sq. ft.

A parallelogram can be defined as a quadrilateral which has equal and parallel opposite sides. The sum of the adjacent angles of a parallelogram is equal to 180° and its opposite angles are equal.

Each side of the square is given 4 1/2 ft,

And the height of each parallelogram 1 1/2 ft.

Now, the area of square is (side)^2 and the area of parallelogram is height × base.

Thus, area of given figure is given as,

Area = (4 1/2)^2 + 2×(4 1/2)×( 1 1/2)

        = 105/4 sq. ft.

Hence, the area of the given figure is 105/4 sq. ft.

Answer:

the amount that nearest to the paper cost with the discount but before tax is $12.83

Step-by-step explanation:

The computation of the amount that nearest to the paper cost with the discount but before tax is shown below:

= Cost of a photo paper - discount

= $13.50  - 5% of $13.50

= $13.50 - $0.675

= $12.83

Hence, the amount that nearest to the paper cost with the discount but before tax is $12.83

Answer:

  a) 102.4

  b) 72.6

  c) 87.5

Step-by-step explanation:

The average value of a function over an interval is the integral of that function over the interval, divided by the width of the interval.

(a) The summer average is ...

  [tex]\text{summer average}=\displaystyle\dfrac{1}{(\frac{1}{4})}\int_\frac{1}{2}^\frac{3}{4}{T(x)}}\,dx=87.5+23.4\cdot\dfrac{2}{\pi}\approx 102.4[/tex]

__

(b) The winter average is similar:

  [tex]\text{winter average}=87.5-23.4\cdot\dfrac{2}{\pi}\approx 72.6[/tex]

__

(c) The annual average is the value added to the cosine function: 87.5

_____

Additional comment

The integral of the cosine function over the period of interest is ...

  ∫cos(2πx)dx = 1/(2π)sin(2πx)

For the limits x=1/2 and x=3/4, this becomes 1/(2π)(-1 -0) = -1/(2π).

When multiplied by -23.4(1/(1/4)), we get +23.4(2/π).

Answer: 9x+6y ≤10  

Step-by-step explanation:

Let x= number of packs of hot dogs .

y =number of packs of hamburger.

Total expenditure = (Charge per hot dog) (number of packs of hot dogs ) +(Charge per hamburger) (number of packs of hamburger.)

i.e. Total expenditure =9x+6y  ( in $)

Jerry can spend a maximum of $100 on the food.

So, Total expenditure ≤ $100

i.e. 9x+6y ≤10  [Required inequality]

Answer:

100 meters is 8.6 meters longer than 100 yards.

Step-by-step explanation:

Conversion of yards to meters.

Each yard has 0.914 meters.

So 100 yards is 100*0.9144 = 91.4 meters.

How many meters longer to the nearest tenth is 100 meters than 100 yards?

100 yards = 91.4 meters

100 - 91.4 = 8.6

So 100 meters is 8.6 meters longer than 100 yards.

Step-by-step explanation:

The first thing you have to do is to look for the number of seconds in one year. You have to multiply 365 days by 86,400 seconds.

Let's solve.

Therefore, one year has 3.1536 x [tex]10^{7}[/tex] seconds.

Next, you have to know the number of seconds in 10 billion years.

The last step is to multiply the number of seconds in 10 billion years to 7 million tons of mass per second.

Answer:

5.7 meters

Step-by-step explanation:

Since the duct tape is to be placed along the diagonal of the square window, Considering the shape formed by one diagonal and two sides of the window. This shape is a right angle triangle.

The diagonal represents the hypotenuse while the sides are the opposite and adjacent. Using Pythagoras theorem, let the length of the diagonal be h

h^2 = 2^2 + 2^2

= 4 + 4

= 8

Taking the root of both sides

h = √8

= 2.828 meters

considering that the duct tape is needed for 2 diagonals, the total length required

= 2.828 * 2

= 5.656

To the nearest tenth of a meter, this becomes

= 5.7 meters

Answer:

A

Step-by-step explanation:

The area of a square is given as the side² thus the side length of the given square will be around 15 inches thus option (B) will be correct.

A square is a geometrical figure in which we have four sides each side must be equal and the angle between two adjacent sides must be 90 degrees.

Length of diagonal of square = √(2) × side

It is known that,

Area of square = Side²

Given, the area is 219 square inches.

Side² = 219

Side = √219 = 14.79 ≈ 15 in.

Hence "The area of a square is given as the side² thus the side length of the given square will be around 15 inches".
