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

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
y = 20

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.

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".

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

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)
