Answer:
14/21
Step-by-step explanation:
1. Find the value of x
Step 1: Write it as an equation.
Step 2: Cross-multiply.
Step 3: Divide both sides by 3.
2. Now that we know the numerator is 14 and the denominator is 21, we can write it as a fraction: 14/21.
Use the Pythagorean Theorm for right triangles where the squares of the two legs equal the square of the hypotenuse.
Plug in the known leg and hypotenuse.
Simplify by squaring.
Isolate b by square rooting both sides.
The result is rounded
The third answer has a y-intercept of 4.
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) =
If the calcium carbonate solution contains 1250 mg per 5 mL,
Then, Ratio of amount of calcium carbonate to amount of solution =
By using proportion we have :-
Hence, 2.5 mL solution were given to the patient.
20 carnations
divide 28 roses by 7 to find one part of the ratio
= 4 ← 1 part of ratio
5 parts = 5 × 4 = 20 ← number of carnations
