Answer:
320 minutes was her time on the previous race
Step-by-step explanation:
Let the time spent on the previous race be x minutes.
Given that at her most recent race, Sue finished in 272 minutes which is 15% less time than the previous race then
x - 15% * x = 272
x - 0.15x = 272
0.85x = 272
x = 272/0.85
x = 320 minutes

3 times the length of a field increased by 4 times the width gives 24 units. Two times the length decreased by 3 times the width is -1 unit. Find the dimensions
Answer:
width = 3
length = 4
Step-by-step explanation:
Ok so you can form a system of equations where w is the width and l is the length:
3l + 4w = 24
2l - 3w = -1
you want to eliminate one of the variables and then solve, so you can first take the top equation and multiply both sides by 2:
6l + 8w = 48
next, multiply the second equation by 3:
6l - 9w = -3
now that both include 6l, you can subtract the two equations
6l + 8w = 48
- (6l - 9w = -3)
17w = 51
divide both sides by 17
w = 3
Plug w = 3 into the equation 3l + 4w = 24:
3l + 4 * 3 = 24
3l + 12 = 24
subtract 12 from both sides
3l = 12
divide both sides by 3
l = 4

The graph which best represents graph A thus option (A) is correct.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
The graph is easy to understand the behavior of the graph.
As per the given data and graphs.
A good scatter plot will be having a reasonable scale on the x and y-axis.
In the graph, The average pain level is in the range of 2 intervals and dosage in 50 intervals as the data also have close to this range.
Thus, graph A represents the best scatter plot.
Hence "The graph which best represents graph A".

Step-by-step explanation:
A ring-shaped region is shown below. Its inner radius is 8m, and its outer radius is 11m. 8m 11m Find the area of the shaded region. Use 3.14 for π. Do not round your answer.
Your answer
Given data
inner radius= 8cm
area= πr^2
area= 3.142*8^2
area= 3.142*16
area= 50.272 cm^2
outer radius= 11cm
area= πr^2
area= 3.142*11^2
area= 3.142*121
area= 380.182 cm^2
Hence the area of the shaded part is
=380.182-50.272
=329.91 cm^2

Find the mean,median,mode, and range:5,2,5,2
Answer:
Mean = 3.5
Median = 3.5
Mode = 5, 2
Step-by-step explanation:
Hope that helps!
Mean: To find the mean, simply add the numbers together and divide by the amount of numbers in the set:
Mean: (5 + 2 + 5 + 2)/4
= (14)/4
= 3.5
Mean = 3.5
Median: To find the median, simply order from least to greatest, and find the middle number in the set. That is your median. In the case of an even amount of numbers in the set, find the mean with the two median numbers (as in this case):
Median: (2 + 5)/2
= 7/2
= 3.5
Median: 3.5
Mode: The Mode is the number that shows up the most frequently. As both given numbers show up the same amount of times (twice), there is no mode.
Mode: None.
Range: The Range is found by subtracting the greatest number with the least number:
5 - 2 = 3
Range: 3
6.) Resuelve: 6(X + 8) - 30 + 7 = 49
Answer:
x=4
Step-by-step explanation:
6(x+8)-30+7=49
6x+48-30+7=49
6x=49-48+30-7
6x=1+23
6x=24
x=[tex]\frac{24}{6}[/tex]
x=4
Step-by-step explanation:
Para resolver esto yo use una app llamada m a t h w a y
(sin los espacios) esta puede estar en varios idiomas, aunque esto se modifica segun el idioma en donde la uses.
6(x+8) -30+7 = 49 1. Simplifica 6(x+8) -30+7
6x+25 = 49 2. Mueve todos los términos que no
contengan x al lado derecho de la ecuación
6x = 24 (25 pasa restando por lo cual sería, 49-25
que es igual a 24.)
3. Divide cada término por 6 y simplifica.
x = 4

Part B: Melissa designed the kite shown and would like to know the minimum amount of fabric needed to cover the kite. Each unit is 1 inch,
48 in
69 in
286 in
572 in?
Answer:
69.4 inches
Step-by-step explanation:
A kite is a quadrilateral (has four sides and four angles) with two pairs of congruent adjacent sides. The diagonals of a kite are perpendicular to each other.
To prove that quadrilateral ADBC is a kite, the diagonals of the kite have to be perpendicular to each other.
AD ⊥ BC.
Since adjacent sides are equal to each other, hence:
BC = BD, AC = AD
The coordinate of the vertices are A(11, 0), B(11, 26), C(0, 18) and D(22, 18)
[tex]BC=\sqrt{(0-11)^2+(18-26)^2} =13.6\ unit\\\\AC=\sqrt{(0-11)^2+(18-0)^2} =21.1\ unit[/tex]
BC = BD, AC = AD
Perimeter of kite = BC + BD + AC + AD = 2BC + 2AC = 2(13.6) + 2(21.1) = 69.4 units = 69.4 inches
