HELP ASAP!!! Please give a step-by-step explanation, or you will be reported!
The table gives the probabilities that orphaned pets in animal shelters in six cities are one of the types listed. The probability that a randomly selected orphan pet in an animal shelter in Austin is a dog is _____ %. The probability that a randomly selected orphaned dog in the same animal shelter in Austin is a Chihuahua is _____ %. (Round to the nearest hundredth.)
For all the dogs: you have 2.65+2.46+3.67+2.91 = 11.69%
Now, the probability of getting a chihuahua would be 3.44/11.69=0.2942= 24.92
Step-by-step explanation:
there ya go!!
Answer:
The probability that a randomly selected orphan pet in an animal shelter in Austin is a dog is 11.71% .
The probability that a randomly selected orphaned dog in the same animal shelter in Austin is a Chihuahua is 29.37% .
Step-by-step explanation:
2.76% + 2.86% + 3.44% + 2.65% = 11.71%
11.71 / 3.44 = .2937
.2937 = 29.37%

9514 1404 393
Answer:
39 units
Step-by-step explanation:
The angle markings tell you this is an equilateral triangle, so all sides are the same length.
10x -11 = 2x +29
8x = 40
x = 5
Then the side length is ...
2x +29 = 2·5 +29 = 39
The length of side KL is 39 units.

The dimensions of a rectangular community garden are 47 ft by 27 ft. The gardeners plan to divide the garden into equal-sized square plots. What is the greatest possible side length of each square plot? Use pencil and paper. How many square plots will there be with this side length? What will be the total area of the square plots? Explain how you can use the total area to check your work.
Answer:
the greatest possible length of each square plot is 1 ft.
1,269 square plots
Step-by-step explanation:
Since the plots are going to be squares then the width and length need to be the same. This means that the largest size of these plots would be calculated as the largest common divisor of the length and width of the garden. In this scenario, since 47 only has two divisors 1 and 47, and 27 is not divisible by 47 then the GCD of these two numbers would be 1. Meaning that the greatest possible length of each square plot is 1 ft.
To calculate the total number of plots needed we divide the square footage of the garden by the square footage of each individual plot like so...
47 * 27 = 1,269 sq. ft.
1 * 1 = 1 sq. ft.
1,269 / 1 = 1,269 plots
Finally, we see that we need a total of 1,269 square plots to cover that same area of the garden.

Find the value of x.
2x
120
70
A. 70
B. 35
C. 25
D. 55
Answer:
Step-by-step explanation:
120 = 2x + 70
120 - 70 = 2x + 70 - 70
50 = 2x
50/2 = 2x/2
x = 25
The interior angle sum of a convex polygon is 2.520 How many sides does the polygon
have?
Complete Question
The interior angle sum of a convex polygon is 2520.How many sides does the polygon have?
Answer:
16 sides
Step-by-step explanation:
The sum of angles in a polygon formula is given as:
(n - 2)180°
Where n = Number of sides of the polygon
Hence:
(n - 2)180°= 2520°
Divide both side by 180°
(n -2) = 2520/180
n - 2 = 14
n = 14 + 2 = 16
Therefore the number of sides the convex polygon has 16 sides.

£25 = 700 rubles, how many £ are in 1,260 rubles?
£
Answer:
45
Step-by-step explanation:
25 = 700
Y = 1260
Now you need to do cross multiplication .
25 X 1260=700Y
Since it's in a multiplying form you can simplify by dividing 700 by 25
1260=700Y/25
1260=28Y
Y=45

Answer:
[tex]\sqrt{125}[/tex]
Step-by-step explanation:
Use Pythagorean theorem since you have a right triangle [tex]15^{2}[/tex] = [tex]10^{2} + x^{2}[/tex]
225 = 100 + [tex]x^{2}[/tex] so x = [tex]\sqrt{125}[/tex]
Answer:
x = 5[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
x² + 10² = 15²
x² + 100 = 225 ( subtract 100 from both sides )
x² = 125 ( take the square root of both sides )
x = [tex]\sqrt{125}[/tex] = [tex]\sqrt{25(5)}[/tex] = 5[tex]\sqrt{5}[/tex] ← in simplest radical form

Simplify: 10x+2x-3= 9
A. x=-1
B. x=-2
C. x=1
D. x=2
Answer:
C. x = 1
Step-by-step explanation:
Combine like terms
10 + 2 − 3 = 9
12 − 3 = 9
Add 3 to both sides of the equation
12 − 3 + 3 = 9 + 3
Add the numbers
12 = 9 + 3
12 = 12
[tex]\frac{12x}{12} = \frac{12}{12}[/tex]
Cancel terms that are in both the numerator and denominator
[tex]x = \frac{12}{12}[/tex]
Divide the numbers
x = 1
Therefore the correct answer is C. x = 1
Answer:
C. x = 1
