The question is below

Anna35 [415]

Answer:

12) A = 27

13) B = 36

14) C = 25

15) D = 30

Step-by-step explanation:

We need to complete the ratio tables

We are given:

Footballs 15 5 20 C D

Baseballs A 9 B 45 54

The table shows the ratio of footballs to baseballs.

We are given the ratio $\frac{Football}{Baseball}=\frac{5}{9}$

All other ratios will also be simplified to get $\frac{5}{9}$

12) Calculate A

Footballs = 15

Baseballs = A

Common ratio is 5/9, we need to find a number that multiplies by 5 to get 15, same number will be multiplied by denominator to get A.

We know that $\frac{5\times3}{9\times3}= \frac{15}{27}$

So, A = 27

13) Calculate B

Footballs = 20

Baseballs = B

Common ratio is 5/9, we need to find a number that multiplies by 5 to get 20, same number will be multiplied by denominator to get B.

We know that $\frac{5\times4}{9\times4}= \frac{20}{36}$

So, B = 36

14) Calculate C

Footballs = C

Baseballs = 45

Common ratio is 5/9, we need to find a number that multiplies by 9 to get 45, same number will be multiplied by numerator to get C.

We know that $\frac{5\times5}{9\times5}= \frac{25}{45}$

So, C = 25

15) Calculate D

Footballs = D

Baseballs = 54

Common ratio is 5/9, we need to find a number that multiplied by 9 to get 54, same number will be multiplied by numerator to get D.

We know that $\frac{5\times6}{9\times6}= \frac{30}{54}$

So, D = 30

In Exercise, solve the equation for k. <br> 22 = 32e-0.02k

lesya692 [45]

Answer:

18.6

Step-by-step explanation:

We are given that

$22=32e^{-0.02k}$

We have to find the value of k.

Divide by 32 on both sides then we get

$\frac{22}{32}=e^{-0.02k}$

$\frac{11}{16}=e^{-0.02k}$

Taking ln on both sides then we get

$ln\frac{11}{16}=-0.02k$

$lne=1$

$ln11-ln16=-0.02k$

$log\frac{m}{n}=logm-logn$

$2.398-2.77=-0.02k$

$-0.372=-0.02k$

$k=\frac{-0.372}{-0.02}=18.6$

Hence, the value of k=18.6

Which two equations would be most appropriately solved by using the quadratic formula?

leva [86]

For this case we have that by definition, the quadratic formula is: $x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}$

A quadratic equation is of the form:

$ax ^ 2 + bx + c = 0$

Option A: This equation can be solved without the quadratic formula

$x ^ 2 = \frac {9} {3}\\x ^ 2 = 3\\x = \pm \sqrt {3}$

Option B:

This equation is not as easy to solve by factoring or as option A. We can use the quadratic formula.

Option C:

$-2x ^ 2 + 5x = 7$

Similarly, this equation can be solved with the quadratic formula

Option D:

$- (x - 3) (x + 9) = 0$

In this factored equation we can see that the roots are

$x_ {1} = 3\\x_ {2} = - 9$

Answer:

Option B, C
