Length = 34 cm
Width= 9 cm
Step-by-step explanation:
Let the width of the rectangle to be.........w
Length is 7 more than three times the width..........3w+7
Perimeter = 86 cm
Perimeter of a rectangle = 2(l+w)
Perimeter of the rectangle = 2 (w + 3w +7)
= 2w +6w + 14
86= 8w +14
86-14 =8w
72=8w
72/8 =8/8w
9=w
Width= 9 cm
Length = 3*9 + 7= 27+7 = 34 cm

Answer:
$32.55
Step-by-step explanation:
8.95 + c = 41.50
subtract 8.95 from 41.50 to get 32.55
this makes c = 32.55
so the cost of the sandals is $32.55

Heres the full question
The following is a histogram showing the distribution per year of the cumulative property damage caused by tornadoes over the period 1950 to 1999 in each of the 50 states and Puerto Rico. The data are in millions of dollars, and the class intervals are 0 to < 10, 10 to < 20, and so forth. The percent of the data with average property damage of under $20M dollars is about:
Data is in the attachment below.
Solution
The frequency below 20 is = 25+6
Total frequency = 50
The percent of the data with average property damage of under $20M dollars is about: = 31/50 = 62%
Answer:
third answer
Step-by-step explanation:
The end behavior of the function indicates that the leading coefficient of x is negative (as x approaches infinity, f(x) approaches negative infinity for cubic functions with negative leading coefficients). This eliminates the first 2 answers. Next, factor out the common factor from the 3rd answer and set it to 0 to see if the roots of the polynomial shown on the graph (x=-3, x=2) match that of the answer.
- factor out -2x since each term in the 3rd answer is divisible by -2x => -2x(x^2+x-6)
- set the factored polynomial equal to 0 => -2x(x^2+x-6)
- divide both sides by -2x => 0 = x^2+x-6
- factor => (x+3)(x-2) = 0
- find zeros by setting both factors equal to 0 => x=-3, x=2
This means that the 3rd answer is correct. The last answer, while having the correct leading coefficient, will produce roots of 3 and -2 instead of -3 and 2, which is shown on the graph.
