Answer:
1. k=2
2. b=2f
3. 68

Explanation

1. y=kx (replace x&y with 2 values)

12=k(6) (isolate k)
/6 /6

2=k *check with another value to see if k truly is 2

2. since the constant of variation is 2, we can see that 2x the number of flowers make up the birds. so...

b(birds/y-value)=2(constant)f(number of flowers)

b=2f

3. input 34 into f, since there are 34 flowers

b=2*34 (use mental math)

b=68
in other words, there will be 68 birds.

a jeweler buys a ring from jewelry maker for $125. he marks up the price by 135% for sale in his store. what is the selling pric
lukranit [14]
You wouls do 125 times 135% and that would be 168.75 then you would do 125 add 168.75 which would equal 293.75 then you would do 293.75 times 7.5% which equals 22.03 then you would do 22.03 add 293.75 and the answer would be 315.78

Solve for y -5y+8=-3y+10 what is the answer
masha68 [24]
-5y + 8 = -3y + 10
We need to get y on one side.
Add 3y to both sides.
-2y + 8 = 10
We need to get 2y by itself.
Subtract 8 from both sides.
-2y = 2
Divide both sides by -2 to solve for y.
y = -1

I hope this helps!

Two integers will be randomly selected from the sets above, one integer from set A and one integer from set B. What is the proba
Fittoniya [83]

Question:

A = {2, 3, 4, 5}

B = {4, 5, 6, 7, 8}

Two integers will be randomly selected from the sets above, one integer from set A and one integer from set B. What is the probability that the sum of the two integers will equal 9?

A. 0.15

B. 0.20

C. 0.25

D. 0.30

E. 0.33

Answer:

Option B: 0.20 is the probability of the sum of the two integers.

Explanation:

The sample space for selecting 2 numbers is given by

4\times 5 = 20

We need to determine the probability that the sum of two integers will be equal to 9.

Hence, we need to add the two integers from the sets A and B such that their sum will be equal to 9.

Hence, the sets are (2,7),(3,6),(4,5),(5,4)

Thus, the total number of sets whose sum is equal to 9 = 4

The probability that the sum of the two integers will equal 9 is given by

P=\frac{4}{20}

P=\frac{1}{5}

P=0.20

Thus, the probability that the sum of the two integers will equal 9 is 0.20

Hence, Option B is the correct answer.

How do you determine the number of zeros to annex in the product of 0.002 and 0.003?
Marat540 [252]
<span>0.002 x 0.003 = 0.000006

the zeroes are multiplied by the power of 10 which is 1/10 in particular.
For example.
The product of a whole number and a decimal number less than 1 will be greater than the whole number multiplied into. For this theorem to be proven. Let us state the mathematical expression into numbers such that </span><span><span>
1. </span> N x 0.1 = N/0.1 < N</span> <span><span>
2. </span> 1 x 0.5 = 0.5 </span><span><span>
3. </span> 2 x 0.1 = 0.2</span> <span><span>
4. </span> 100 x 0.55 = 55</span><span>  </span>

<span>These three examples and stances then suggest the claim that the product is not equal to the whole number used in the equation.<span>
