A seed Company planted a floral mosaic of a national flag. The perimeter of the flags 540 feet. Determine the flags length and w

stiv31 [10]

Answer:

Length of the flag is 190 feet and width of the flag is 80 feet.

Step-by-step explanation:

Given:

Perimeter of the flag = 540 feet

We need to find the length and width of the flag.

Let the length of flag be 'l'.

Let the width of the flag be 'w'.

Now given:

length is 110 feet greater than the width

Length of the flag $l = 110+w$

Now we know that,

Flag is in rectangular shape.

So Perimeter of rectangle is given by 2 times sum of length and width.

framing in equation form we get;

$2(l+w) =540$

Now dividing both side by 2 we get;

$\frac{2}{2}(l+w)=\frac{540}{2}\\\\l+w =270$

Now Substituting the value of 'l' in above equation we get;

$110+w+w=270\\\\110+2w=270$

Subtracting both side by 110 we get;

$110+2w-110=270-110\\\\2w= 160$

Dividing both side by 2 we get;

$\frac{2w}{2}=\frac{160}{2}\\\\w=80\ ft$

Width = 80 feet

Length $l =110+w =110+80 =190 \ ft$

Hence Length of the flag is 190 feet and width of the flag is 80 feet.

The number of cans in the layers of a display in a supermarket form an arithmetic sequence. The bottom layer has 28 cans; the ne

Aleksandr-060686 [28]

Answer: 145 cans

Step-by-step explanation:

arithmetic sequence

aₙ = a₁ + (n-1).r

aₙ → last term

a₁ → 1st term

n → quantity of terms

r → common difference

a₁ = 1 (one can at the top)

aₙ₋₁ = 25

aₙ = 28

To find out How many cans are in the entire display, we need the SUM of the arithmetic sequence: S = (a₁+aₙ)n/2

∴

S = (1+28).n/2

n = ?

aₙ = a₁ + (n - 1).r

r = 28 - 25 = 3

28 = 1 + (n - 1).3

27 = (n - 1).3

27/3 = (n - 1)

9 = n - 1

n = 9 + 1 = 10

S = (1+28).n/2

S = (1+28).10/2 = 29.10/2 = 29.5 = 145
