A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 400 feet. Determine the flag's length and width if the length is 80 feet greater than the width.
Answer:
Length-140 ft
Width-60 ft
Step-by-step explanation:
I tried many different combinations
Answer: 120 ft
Step-by-step explanation:
So the equation we start off with is
2l+2w=400 in this situation
Since we know one length is 80,
2l would be 160.
So now we have 160+2w=400
Now we can use the perimeter to find the width now that we know the 2l.
400-160=2w
2w=240
240÷2
W=120

Answer:
x = 4, y = -6
Step-by-step explanation:
u can plug it in if u don't believe me
Answer:
x = 4
Step-by-step explanation:
3x - 4y = 36
5x + 2y = 8 ( multiply all by two )
3x - 4y = 36
10x + 4y = 16
13x = 52
Divide by 13
x = 4
Which of the following is the correct representation of permutation?

The Correct option is (b) i.e. P (n , r)
What is Permutation?
A Permutation is the number of way a set can be arranged or the number of ways things can be arranged.With a permutation, the order of numbers matters.The main types of permutations are those with repetition and those without, although other less common types include permutations with multi-sets and other permutation.P (n , r) = n! ÷(n-r)!
where,
n = total items in the set;r = items taken for the permutation;"!" denotes taking the factorial.The Correct option is (b) i.e. P (n , r)

A discount sports store has been open for 17 years. For this time period, the store’s annual revenue, R (in millions of dollars), can be modeled by the function
(picture) where t represents the number of years since the store opened. Determine the number of years the store was in business when the revenue amount reached $8.2 million.
9514 1404 393
Answer:
10 years
Step-by-step explanation:
We want to find the value of t when R = 8.2. Equivalently, we want to find t when ...
0.001(-t^3 +16t^2 +900t -1400) -8.2 = 0
A graphing calculator is useful for finding real solutions to this equation. The attachment shows the store was in business 10 years when revenue reached 8.2 million.

Answer:
25 metres per second
Step-by-step explanation:
just divide 100 by 4 and you will get the answer.☺️☺️
Answer:
25 m/s
Step-by-step explanation:
train a travels at 12.5 m/s and will arrive at 100m in 7s.
train b arrives at the same distance, 100m, in 4s. so that means train b is going at 100m/4s and then simplify that
therefore train b is moving at 25m/s

The coordinates of the vertices of △DEF are D (1, 2) , E (2, 0) , and F (−1, 0) .
The coordinates of the vertices of △D′E′F′ are D′ (1, −4) , E′(2, −2) , and F′ (−1, −2) .
What is the sequence of transformations that maps △DEF to △D′E′F′ ?
Drag and drop the answers into the boxes to correctly complete the statement.
A sequence of transformations that maps △DEF to △D′E′F′ is a _____ followed by a ________.
Answer:
Step-by-step explanation:
△D′E′F′ is reflection of △DEF across y = - 1.
The transformation of the △DEF to △D′E′F′ is as follows; The △D′E′F′ is a reflection of △DEF across y = - 1.
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
As per the given triangle △DEF with vertices D (1, 2) , E (2, 0) , and F (−1, 0) .
The plot of the above triangle has been plotted below,
As per the given triangle △D′E′F with vertices D′ (1, −4) , E′(2, −2) , and F′ (−1, −2) .
The plot of the above triangle has been plotted below,
It is clear that △DEF is reflected and how much is reflected can be known by making equal distance.
Since it equals apart from y = -1 thus it will be a reflection of y = -1.
Hence "The transformation of the △DEF to △D′E′F′ is as follows; The △D′E′F′ is a reflection of △DEF across y = - 1".

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
y = -7x + 6
y = -10x
Step 2: Solve for x
Substitution
Substitute in y: -10x = -7x + 6Add 10x to both sides: 0 = 3x + 6Isolate x term: -6 = 3xIsolate x: -2 = xRewrite: x = -2Step 3: Solve for y
Define equation: y = -10xSubstitute in x: y = -10(-2)Multiply: y = 20Answer:
x = -2
y = 20
Step-by-step explanation:
y = -7x + 6
y = -10x
y = -10x
-7x + 6 = -10x
3x = -6
x = -2
y = -7x + 6
y = -7 ( -2 ) + 6
y = 14 + 6
