Answers
Answer:
- 1/4 (2x + 5y)Step-by-step explanation:
Divide each term by - 1/4 first
-1/2x ÷ (- 1/4) = 1/2x × 4 = 2x-5/4y ÷ (- 1/4) = 5/4y × 4 = 5yNow facor out - 1/4

Answers
The amount of ml required for the 1500mg order is 2.1ml
Conversion of grams to milligramConversion factors are used to convert units from one form to another.
Using the conversion factor
2.2g = 2200mg
x = 1500mg
Find the ratio of the expressions
2.2/x = 2200/1500
2200x = 2.2 * 1500
2200x = 3300
X = 3300/2200
x = 1.5grams
Since the dosage is 2.2 g/3 ml, then for 1.5grams
Volume required = 1.5*3/2.2
Volume required = 2.1 ml
Hence the amount of ml required for the 1500mg order is 2.1ml

See the figure below. Which graph is the most appropriate to describe the height over time of a helium ballon that was accidentally let go and later burst?
Answers
Answer:
D
Step-by-step explanation:
We expect the height of a helium balloon to be increasing, up to the point where it bursts.
The only graph that shows consistently increasing altitude with a final drop is graph D.
_____
Additional comment
The graph of D shows the altitude increases at an increasing rate. The buoyancy force decreases with altitude, so we expect the balloon would actually have a decreasing rate of altitude increase. The actual curve would likely be concave downward.

Step-by-step explanation:
Given;Radius (r) = 1/2To Find;Volume of sphereFormula;Volume = 4/3 πr³Now,
V = 4/3 × 22/7 × (1/2)³
V = 4/3 × 22/7 × 1/8
V = 1/3 × 11/7 × 1
V = 11/21 = 0.52 cubic units

A dragon flew 300 miles from his castle to visit a friend. Flying with the wind, his trip took 2 hours. His return trip against the wind took 3 hours. What was the speed of the wind and the speed of the dragon in still air?
Please help me. I WILL mark brainliest and give lots of points.
Answers
Answer:I’m not sure about the wind but the speed of the dragon is 125mph
Step-by-step explanation:Remember,
Speed=Distance/Time
Distance=Speed x Time
Time=Distance/Speed
Knowing that the distance in both trips was the same, we can say that he flew his trip 150mph (Speed=300/2) the first time and 100mph (Speed=300/3) the second time. Next, we find the average of 150 and 100 and that is (100+150)/2 which is 125. I’m sorry I couldn’t find the speed of wind, but in my defense, I’m only in 6th grade. Hopefully that helped you, good luck!

Speed of the wind was

A. sin^2 θ
B. sin(-θ)
C. tanθ
X. -sinθ
Y. sinθ/cosθ
Z. 1-cos^2θ
Answers
The ABC and XYZ statements are trigonometric statements
The equivalent of A is ZThe equivalent of B is XThe equivalent of C is YHow to match the statements?A. sin^2 θ
To do this, we apply the following trigonometric ratio
sin^2 θ + cos^2 θ = 1
Subtract cos^2 θ from both sides
sin^2 θ = 1 - cos^2 θ
Hence, the equivalent of A is Z
B. sin(-θ)
Assume that θ is an acute angle, then we have:
sin(-θ) = -sinθ
Hence, the equivalent of B is X
C. tanθ
Using the trigonometry formula, we have:
tanθ = sinθ/cosθ
Hence, the equivalent of C is Y

what is the angle of elevation of the sun when the shadow of a pole of 18m high is 6√3m long? ( i need step by step explanation pls I'm having a class test tmr pls help)
Answers
Answer:
See diagram below
Step-by-step explanation:
arctan (angle ) = 18 / (6 sqrt3) = 60 degrees
Step-by-step explanation:
height of pole = 18m = p
length of shadow = 6[tex]\sqrt{3}[/tex] m = b
now,
tan α = p/b
= 18/6[tex]\sqrt{3}[/tex]
= [tex]\sqrt{3}[/tex]
or, tan α = tan 60
α = 60
Therefore angle of elevation of the sun is 60.
