Romeo shot 15 free-throws in last night's game. His coach told him he had an 80% free-throw percentage. How many did he make? (c

Fofino [41]

Answer:

30 throws

Explanation:

Given

Total throw shot by Romeo = 15 throws

If he had an 80% free-throw percentage;

additional throw = 80% of 15

additional throw = 0.8 * 15

additional throw = 12 throws

Toal throws made = 15 + 12

Total throws made = 30 throws

Hence the made 30 throws

Which table does not show a direct variation?

stiv31 [10]

Answer:

Table J

Step-by-step explanation:

A direct variation is a simple relationship between x and y.

When you are looking for the direct relationship you should use the formula for it y=kx, or you could just divide y over x ( $\frac{y}{x}$ ).

Analysing Table F:

The relationship between x and y is 4.

$\frac{-8}{-1}=4\\\\\frac{-4}{-1}=4\\\\\frac{0}{0}= origin\\\\\frac{4}{1}=4$

The origin is fine and doesn't ruin the relationship.

Analysing Table G:

The relationship between x and y is 5.

$\frac{5}{1}=5\\\\\frac{10}{2}=5\\\\\frac{15}{3}=5\\\\\frac{20}{4}=5$

Analysing Table H:

The relationship between x and y is $\frac{1}{3}$ .

$\frac{0}{0}=origin\\\\\frac{1}{3}=\frac{1}{3}\\\\\frac{2}{6}=\frac{1}{3}\\\\\frac{3}{9}=\frac{1}{3}$

Like I said before the origin doesn't ruin the relationship so it's fine.

Analysing Table J:

This one doesn't have a direct relationship between x and y.

$\frac{1}{1}=1\\\\\frac{4}{2}=2\\\\\frac{9}{3}=3\\\\\frac{16}{4}=4$

How many mEq of KCI will the patient receive in 24 hours?

Brilliant_brown [7]

10% = 10g/100ml. Ergo, 15ml/100ml (10g) = 1500mg of KCL
.9% NACL = 9g/1000mL, Ergo = 9000mg NaCl
Now we have to figure out how many mEqs of each salt we have.
MW of NaCl = 58.5
MW of KCl = 74.5
So, in moles, we have:
1500 KCl / 74.5 = 20.13 mmol KCl
9000 NaCl / 58.5 = 153.85mmol NaCl
Because the valence of both ions is one, as an example, it would be both 20.13 mEq of Cl- and K+ from 20.13 mmoles of KCL.
So, just add the two together, 20.13 + 153.85 = 174-ish.
