Answers

you have the area of the squares
100 in^2
area of a square = l*w
so length and width of the square both equal 10in
there are 4 squares going across the semi circle so...
diameter of semicircle is 10+10+10+10 =40in and radius is 20in
to find area of semicircle the formula is 1/2 pi r^2
so plug in the numbers 1/2(3.14) (20)^2 = 628 in ^2
now add that to area of big square part of window
40 inches length * 40 inches width = 1600in^2 (or you can just add them all up )
add up the areas now 1600+628= 2228 in^2
i think that is right

a) We know that the radius of the top of the window is two side lengths of a square. Since each square has a side length of 10 inches, the radius of the half-circle portion is 20 inches. The area of a half-circle is (pi*r²)/2 (r being radius and pi being 3.14). There are 16 squares as well. So the equation is ((3.14*20²)/2) + (16*100)=2,228 in²
b) The next part's a little tricky, but just add 4 inches to the radius and 4 inches to all of the affected outer-rim squares. You should get 3016.32 in²

What is 109 percent as a decimal?

Answers

1.09

Hope I Helped You!!! :-)

Have A Good Day!!!

Answer:

1.09

Step-by-step explanation:

"Percent" means "per 100" or "over 100". To convert 109% to a decimal rewrite 109 percent in terms of per 100 or over 100.

109% = 109 over 100 or,

109%=109100109 over 100 is the same as 109 divided by 100. Completing the division we get:

109 ÷ 100 = 1.09

Therefore, we have shown that

109% = 1.09

Simplified Conversion:Remove the percent sign % and divide by 100.

109 ÷ 100 = 1.09

Shortcut Conversion:Move the decimal point 2 places to the left and remove the percent sign %

109% becomes 1.09

At the end of a snow storm,Allison saw there was a lot of snow on her front lawn.The temperature increased and the snow began to melt at a steady rate.After the storm,the snow started to melt at a rate of 0.75 inches per hour and is known that 4 hours after the storm ended,the depth of snow was down to 9inches.Write an equation for the function S(t),representing the depth of snow on Allison lawn,in inches,t hours after the snow stopped falling

Answers

The equation for the snow in the lawn after t hours and melting at a rate of 0.75 inches per hour will be equal to S = x - 0.75(t).

What is an expression?

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the given information in the question,

Let the initial amount of snow in the lawn is x inches.

Rate of melting of snow per hour = 0.75 inches per hour.

The equation for t hours, after melting of ice,

S = x - 0.75(t)

Here, t is the time in hours and x is the initial amount of ice in the lawn.

Last summer, karl went to the beach every 5 days. Antonia went to the beach every 7 days. how often did they get see each other at the beach?(need the answer asap!)

Answers

The day is 35 when they get to see each other at the beach after finding the LCM of the numbers 7 and 5.

What is LCM?

It is defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.

It is given that:

Last summer, Karl went to the beach every 5 days.

Antonia went to the beach every 7 days.

To find the day they get to see each other at the beach:

Find the LCM(lowest common factor) of 7 and 5:

7: 7, 14, 21, 28, 35,

5: 5, 10, 15, 20, 25, 30, 35

The common number is 35.

Thus, the day is 35 when they get to see each other at the beach after finding the LCM of the numbers 7 and 5.
