Answer:

1/3

Step-by-step explanation:

So because of BODMAS / PEDMAS / whatever you call it, you do the brackets first.

(7-2) = 5

5 squared is 25

So 25 is on the top.

Then we do the bottom one. We do square/cubed/quadrupled numbers first, so 3 to the power of 4 is 81.

4+81=85

85-10=75

So the bottom number is 75.

25 / 75 is the fractions so simplified that would be 1/3

Find the value of x to the nearest tenth. (The last answer is 13.3)

Julli [10]

Your answer is the first option, 8.0. You can find this by using the sine rules for sides, so:
10/sin(90) = x/sin(53)
× sin(53)
7.98 = x
And 7.98 rounded to the nearest tenth is 8.0.
I hope this helps!

A patient is given a solution containing 0.625 g of calcium carbonate. If the calcium carbonate solution contains 1250 mg per 5

Dmitrij [34]

Answer: 2.5 mL

Step-by-step explanation:

Given : A patient is given a solution containing 0.625 g of calcium carbonate.

i.e. Patient required calcium carbonate = 625 mg [∵ 1 g = 1000 mg]

Let x be the amount of solution ( in millimeters) given to the patients.

Ratio of amount of calcium carbonate (mg) to amount of solution (ml) = $\dfrac{625}{x}$

If the calcium carbonate solution contains 1250 mg per 5 mL,

Then, Ratio of amount of calcium carbonate to amount of solution = $\dfrac{1250}{5}$

By using proportion we have :-

$\dfrac{625}{x}=\dfrac{1250}{5}\\\\\Rightarropw\ x=\dfrac{5\times625}{1250}=2.5$

Hence, 2.5 mL solution were given to the patient.
