A seed company planted a floral mosaic of a national flag. The perimeter of flag is 2,340 ft determine the flag’s width and length if the length is 270ft greater than the width.
Answer:
Width: 450 feet
Length: 720 feet
Step-by-step explanation:
So we start with the equation to find the perimeter -
2l + 2w = p
l = length
w = width
p = perimeter
We insert the 2,340 ft as the perimeter -
2l + 2w = 2,340 ft
Now we find another equation for the "length is 270 ft greater than width" -
l = 270 ft + w
Using substitution, we substitute the y in the first equation with 270 ft + w -
2 (270 ft + w) + 2w = 2,340 ft
540 ft + 2w + 2w = 2,340 ft
540 ft + 4w = 2,340 ft
4w = 2,340 ft - 540 ft
4w = 1,800 ft
w = 1,800 ft / 4
w = 450 ft
Now to find the width we substitute the w with 450 ft -
l = 270 ft + w
l = 270 ft + 450 ft
l = 720 ft
Check -
2 * 720 ft + 2 * 450 ft = 2,340 ft
1,440 ft + 900 ft = 2,340 ft
2,340 ft = 2,340 ft (Correct)

Step-by-step explanation:
Mary has 2 1/5 hours before she needs to meet her friend. She needs to take care of 7 chores before then. How much time can she allocate to each chore?
around 19 minutes ^^
(18.85 minutes)
Mary can allocate to each chore around 18.85 minutes.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
It is given that Mary has 2 1/5 hours before she needs to meet her friend. She needs to take care of 7 chores before then.
Hence, we get
2 and 1/5 hours = 132 minutes (120 + 12)
thus, Mary will have 132/7 = 18.85714285714286 minutes for each chore.
Or around 18.85 minutes for each chore
Therefore, she can allocate to each chore around 18.85 minutes.

10x + 8 = 3(x – 2)
10x + 8 = 3x
Answer:
dfq
Step-by-step explanation:
1.
10x + 8 = 3(x – 2)
10x + 8 = 3x - 6
10x - 3x = -8 -6
7x = -14
x = -14/7
x = -2
2.
10x + 8 = 3x
10x - 3x = -8
7x = - 8
x = -8/7

Find the equation of the straight line passing through the point (3,5) which is perpendicular to the line y=3x+2
Answer:
the desired equation is y = (-1/3)x + 6
Step-by-step explanation:
Let the given line be A: y=3x+2
The slope of line A is m = 3.
The slope of any line B which is perpendicular to line A is the negative reciprocal of the slope of A: m = -(1/3).
The particular perpendicular line that passes through (3, 5) is then
5 = (-1/3)(3) + b, which simplifies to 5 = -1 + b, or b = 6.
Thus, the desired equation is y = (-1/3)x + 6

1. The amount of Kelly's paycheck varies directly with the number of hours
she works. Kelly receives $139.80 for 12 hours of work.
(a) Write a direct variation equation that relates the amount of Kelly's paycheck, y, to the number of hours, x,
that Kelly works.
(b) Use the equation to find the amount of Kelly's paycheck when she works 40 hours.
Answer:
Step-by-step explanation:
y = kx ; k = [tex]\frac{y}{x}[/tex]
~~~~~~~~~~
(a). 139.8 = k × 12
k = 139.8 ÷ 12 = 11.65 ⇒ Kelly earns $11.65 per hour
y = 11.65x
(b). y = 11.65 × 40 = 466
Kelly's paycheck when she works 40 hours is $466.00

Which number is a rational number? OA √15 OB. 2.6457513110... O c. 17.156 OD. 3√85
Answer:
"O c. 17.156"
Step-by-step explanation:
A is not a rational number because it cannot be written as a fraction [with two integers] or an integer (the square root of 15 is equal too 3.87298334...)
B is not a rational number because it also goes on forever, just like A.
C is a rational number because it does not go on forever.
D is like A and B, it goes on forever.

: Is the relation a function? If so, is it one-to-one or not one-to-one?
Answer:
Linear Function
Step-by-step explanation:
Ok, so this is a function. This is because none of the X's repeat with a different Y. "Every Input has EXACTLY one Output"
BUT: I don't know what a One-to-one is. I would guess it means linear, which means it's a straight line on a graph. If that's the case, then it would be infact a Linear Function.
Answer:
Step-by-step explanation:
honestly, it's most likely a function. I know it's a function, but I don't understand what not one-to-one means, so, I guess it's just a function and nothing else?
