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,,,,,,

How do I find b of the traingal

V125BC [204]

Answer:

Pythagorean Theorum:

16ft

Step-by-step explanation:

pythagorean theorum states a^2+b^2=c^2

it only works for right triangles, c is the hypotenuse, a and b are the legs

so to find b we plug in the info we have!

7.8^2+b^2=17.8^2

next we simplify:

60.84+b^2= 316.84

subtract 60.84 from both sides to isolate the variable:

b^2=256

square root both sides

b=16

16ft is the answer

I hope this helps!

Sandra recieved 15 $20 bills for her birthday. She spent 3/5 and saved 2/5 how much did Sadra spend and how much did she save.

julia-pushkina [17]

The first step to solving this problem is to find out how much money Sandra received for her birthday. We can find this out by multiplying 15 by 20,, which will look like the following:
15 x 20 = 300
Now that we know that Sandra received a total of $300 for her birthday,, we need to multiply the 300 by $\frac{3}{5}$ to see how much she spent.
300 x $\frac{3}{5}$
First we need to reduce the numbers with 5
60 x 3
Then multiply the numbers together to find out how much money Sandra spent
180
Now,, we need to multiply 300 by $\frac{2}{5}$ to see how much of her money she saved
300 x $\frac{2}{5}$
Reduce the numbers with 5
60 x 2
Then multiply the numbers together to see how much money Sandra saved.
120.
This means that Sandra spent $180 and saved $120.

Step-by-step explanation:

you know how to multiply fractions ?

a/b × c/d = (a×c)/(b×d)

the 2 top parts are multiplied and the 2 bottom parts are multiplied.

the existing answers in "Model" are wrong.

when we multiply the actual size by the scaling factor, we get the model size.

2 1/3 = (6+1)/3 = 7/3

7/3 × 2/5 = 14/15

this is s little bit smaller than 1, and definitely not 1 1/3 (more than 1).

similar with the width.

1 3/7 = (7+3)/7 = 10/7

10/7 × 2/5 = 20/35 = 4/7 (and not 3/4)

so, this is all wrong.

the question is, if maybe the specified scaling factor of 2/5 is wrong.

so, let's see what the scaling factual is for the given model sizes.

7/3 × f = 1 1/3 = (3+1)/3 = 4/3

7f = 4

f = 4/7

now let's try this scaling factor for the width :

10/7 × 4/7 = 40/49

no, this is also not 3/4 (not even close). this is much closer to 4/5.

therefore, I assume now that the actual and scale numbers are correct, and we calculate all the correct model numbers.

so, again

the model length is actually 14/15

the model width is 4/7

the model height is

(8+1)/8 × 2/5 = 9/8 × 2/5 = 18/40 = 9/20

the model door width is

6/7 × 2/5 = 12/35

the model door height is

7/8 × 2/5 = 14/40

and because the scaling factor (2/5) is smaller than 1, actually smaller than 1/2, the model numbers will be smaller then even half the actual numbers. as our results above show.
