$w + 3 = w + 6 \\ w - w + 3 = w - w + 6 \\ 3 = 6$
Since 3 does not equal 6, therfore the answer is no solution.

Analyze tables use the table that shows the percents of blood types of 145 donors during a recent blood drive

Alenkinab [10]

Answer:

a. 16

b. 80

c. Blood type AB

Step-by-step explanation:

Given:

O = 45%

A = 40%

B = 11%

AB = 4%

Total number of donors = 145

a. No. of donors that had type B blood = $\frac{11}{100}*145 = \frac{1,595}{100} = 15.95$

Type B blood donors ≈ 16

b. No. of blood donors without blood type O = $\frac{40 + 11 + 4}{100}*145 = \frac{55}{100}*145 = \frac{7,975}{100} = 79.75$

Those without blood type O ≈ 80

c. Find the number of people that had type AB:

Type AB = $\frac{4}{100}*145 = 5.8$ ≈ 6. This is less than 10 donors.

Therefore, blood type AB had less than 10 donors.

Step-by-step explanation:

The explanatory is the independent variable, or the variable that goes on the x-axis of a graph. Here, that could be time or political affiliation.

A ship leaves port at 1:00 P.M. and travels S35°E at the rate of 27 mi/hr. Another ship leaves the same port at 1:30 P.M. and tr

Len [333]

To solve this problem you must apply the proccedure shown below:

1. You must apply the Law of Cosines, as you can see in the figure attached. Then:

- The first ship travels at $27 mi/hr$ in for two hours. Therefore, the side $a$ is:

$a=(27 mi/hr)(2 hr)=54mi$

- The second ship travels at $18 mi/hr$ for $1.5 hours$ . Therefore, the side $b$ is:

$b=(18mi/hr)(1.5hr)=27mi$

- Now, you can calculate $c$ :

$c=\sqrt{54^{2}+27^{2}-2(54)(27)Cos(55)}=44 mi$

The answer is: $44 miles$
