This the problem with non-SI units, conversion is such a
nightmare. Anyhow, given $98 per cu.yd and total cost of $72.59, the volume of
concrete is 0.7404 cu.yd. Converting the given dimensions to yards:
3.33 yd x (1/12) yd
Solving for the unknown dimension given volume and 2 other
dimensions:
.7407 cu. Yd = (3.333 yd)(1/12 yd)(x)
X = 2.6678 yd or 8 feet
Answer: 480 milligrams
Step-by-step explanation:
We can solve this by using direct proportion whereby y = kx
where,
x = patient's weight = 92 pounds
k = constant
y = milligrams of antibiotics = 320
Using y = kx
320 = 92k
k = 320/92
k = 3.4782609
The antibiotic that should be given to a patient who weighs 138 pounds will be:
y = kx
y = 3.4782609 × 138
y = 480 milligrams
The antibiotic that should be given to a patient who weighs 138 pounds is 480 milligrams.
Answer:
Step-by-step explanation:
r=13in
Perimeter of a circle is 2πr
P=2×22/7×13
P=81.71in.
If it will make 3 revolution then it will have move 3 times it perimeter
3×81.71
245.14in
The distance the wheel will traveled is 245.14in
