Answer:
Let W be the width of the rectangle. The length will then be 6W (six times the width). The area is length times width. if this equals 216, then you have an equation
(6W)(W) = 216
6W2 = 216
W2 = 36
W = 6.
The width is 6 ft and the length must then be 6W = 36 ft.
To find the perimeter, use the formula
P = 2L + 2W.
Plug in:
P = 2(36) + 2(6) = 72 + 12 = 84 ft.
The perimeter is 84 ft. (Remember that area has units length units squared and perimeter has units same as length.)

Answer:
90
Step-by-step explanation:
Firstly, you divide 108 by 6, since 108 can't be divided by 5, and 108 divided by 6 gives you 18. Then you multiply 18 by 5, which gives you 90. Boom.
Answer: the answer is 90

2x + 5y= 10; (4,9)
Write answer in slope intercept form.
Answer:
y = 5x - 5/2xy + 79
Step-by-step explanation:
First we need to solve for m which is slope.
Subtract 5y from both sides
2x = 10 - 5y
Then divide each term by 2
2x/2 = 10/2 + -5y/2
Then simplify to the left
x = 10/2 + -5y/2
Then simplify the right side
x = 5 - 5y/2
Next we have to find the value of b using the formula y = mx + b
So
y = (5 - 5y/2) * x + b
y = (5 - 5y/2) * (4) + b
9 = (5 - 5(9)/2) * (4) + b
Rewrite
(5 - 5(9)/2) * 4 + b = 9
Simplify more
Multiply 5 by 9
(5 - 45/2) * 4 + b = 9
Multiply by 2/2 to write 5 as a fraction
5 * 2/2 - 45/2) * 4 + b = 9
Then combine 5 and 2/2
(5 * 2/2 - 45/2) * 4 + b = 9
Combine the numerator over the denom
5 * 2 - 45/2 * 4 + b = 9
Simplify the numerator
-35/2 * 4 + b = 9
Cancel the common factor of 2
-35 * 2 + b = 9
Multiply
-70 + b = 9
Move the terms without b to the right side
b = 9 + 70 > b = 79
Now we substitute all the values into y = mx + b
y = 5x - 5/2xy + 79
53,5_8,769 is divisible by 9

Step-by-step explanation:
Ela is buying $110 chair. She has a coupon for 15% off. How much does she pay for the chair if sales tax is 6%?
Answer:
$99.11 dollars
Step-by-step explanation:
Given the following question:
$110 dollars for a chair...
15% off from a coupon...
Then a 6% sales tax....
[tex]\frac{15\times110}{100} =15\times110=1650\div100=16.5[/tex]
[tex]110-16.5=93.50[/tex]
The chair costs $93.50 dollars after the 15% off coupon.
Now the 6% sales tax:
[tex]\frac{93.5\times6}{100} =93.5\times6=561\div100=5.61[/tex]
[tex]93.5+5.61=99.11[/tex]
[tex]=99.11[/tex]
After the 15% coupon and the 6% sales tax, the chair will cost "$99.11 dollars."
Hope this helps.
The equation shows an unknown number. PLEASE ANSWER, QUICKLY.
Solution:
Note that:
Given equation: x ÷ 3/7 = 7/15Simplify the given equation to solve for x.
x ÷ 3/7 = 7/15=> x × 7/3 = 7/15=> 7x/3 = 7/15=> 7x = 7/5=> 35x = 7=> x = 1/5Check:
1/5 ÷ 3/7 = 7/15=> 1/5 x 7/3 = 7/15=> 7/15 = 7/15 (True)Hoped this helped!

How does the graph of f(x) = (x − 9)4 − 3 compare to the parent function g(x) = x4?
Using translation concepts, we have that the graph of f(x):
Was shifted 9 units to the right and 3 units down.
The parent function is given by:
The translated function is given by:
The first transformation was that , thus, it was shifted 9 units to the right.
Then, 3 was subtracted from the function, which means that it was shifted down 3 units.

1) 2 and 2/10
2) (2*10) = 20
3) add 20 to 2, then put it on the /10
4) 22/10, then reduce the fraction
5) 11/5
Final answer: 11/5

hey I got a question what grade that math from
2(x+5)-7=3(x-2)
Pls help ! find value of x
Answer:
dasd
Step-by-step explanation:
Given:
2(x + 5)-7= 3(x - 2)
To Find:
• Value of x
Solution:
⇒ 2(x + 5)-7= 3(x - 2)
⇒ 2x+10-7= 3x - 6
Rearranging the like terms,
⇒ 3x-2x = 10 + 6-7
⇒x=16-7
⇒x=9
Verification:
⇒ 2(x + 5)-7= 3(x - 2)
Putting x = 9,
⇒2(9+5)-7= 3(9 - 2)
2(14)-7= 3(7)
⇒28-7=21
⇒ 21 = 21
→ LHS = RHS
HENCE VERIFIED!!!

When a triangle is cut by a line parallel to its base, the resulting two triangles are similar. That means corresponding sides are proportional (their ratios are equal).
There are several ways the ratios can be written, but I like to choose one that has the variable in the numerator. Here's the proportion and its solution.
[tex]\dfrac{x+5}{16}=\dfrac{30}{20}\\\\x+5=24\qquad\text{multiply both sides by 16}\\\\x=19\qquad\text{subtract 5 from both sides}[/tex]
_____
Additional comment
Technically, the corresponding sides of the triangles would be ...
entire long side of larger triangle: ((x+5) +30) and long side of smaller triangle (30)entire short side of larger triangle (36) and short side of smaller triangle (20)Since the parts labeled (x+5) and 16 are each the same fraction of their entire side, those parts are corresponding also, and will have the same proportion as other corresponding sides.

Parallel lines are preserved in which of the following types of transformations? 1. rotations II. reflections III. translations
Answer:
All of the above.
Step-by-step explanation:
Translation, reflection, and rotation are isometries, since they preserve length. Therefore translation, reflection and rotation are congruency transformations. Further if we only require that parallel lines be mapped onto parallel lines, we get the shears and stretches.

Answer: 352496
Step-by-step explanation:
First, to find 20% of 440,620, you can multiply:
0.2 x 440,620 = 88,124
Then, to find the new weight of the ship, you can subtract the 20% that was just found (88,124) from the ship's original weight (440,620) to get:
440,620 - 88,124 = 352,496
Therefore, the ship's weight is now 352496.
