then
815/35= 23.28
Which sentence is correct?A.B.C.D.
Answer: B is correct
Step-by-step explanation:
if you do 2 ÷ 5 you get 0.4. But that isn't an option. So, the only other possibility would be -2 ÷ 5 which gives us -0.4, and that makes sense.
I'm not the greatest at explaining this one but hopefully, this helps!

Aiko types at a rate of 50 words per minute.
After typing at the same rate for 3 minutes, he has typed a total of 150
words.
This situation can be represented with a linear equation written in point- slope form, where x represents the number of minutes and y represents the number of words.
Use this information to complete each statement about the linear equation.
Answer:
Slope: 50x
One point will be: (1,50)
Equation: y = 50x
Step-by-step explanation:
Answer:
The slope of the linear equation is *50
One point on the graph of the linear equation will be *(3, 150)
This linear equation can be written as *y – 150 = 50(x – 3)

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)
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.

Order: abc 1500 mg. stock: abc 2.2 g/3 ml. how many ml(s) will you give? (round the answer to the nearest tenth)
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

Factor −1/4 out of −1/2x−5/4y..ㅤ
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
- 1/2x - 5/4y = - 1/4 (2x + 5y)Part A Are squares also rectangles? Explain.
Answer:

Find the volume of the sphere. radius is 1/2
Answer:
The answer is 11/21 or 0.52 cubic units
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
Thus, The volume of sphere is 11/21 or 0.52 cubic units.
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?
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.

A student solves the following equation for all possible values of x: startfraction 8 over x 2 endfraction = startfraction 2 over x minus 4 endfraction his solution is as follows: step 1: 8(x – 4) = 2(x 2) step 2: 4(x – 4) = (x 2) step 3: 4x – 16 = x 2 step 4: 3x = 18 step 5: x = 6 he determines that 6 is an extraneous solution because the difference of the numerators is 6, so the 6s cancel to 0. which best describes the reasonableness of the student’s solution? his solution for x is correct and his explanation of the extraneous solution is reasonable. his solution for x is correct, but in order for 6 to be an extraneous solution, both denominators have to result in 0 when 6 is substituted for x. his solution for x is correct, but in order for 6 to be an extraneous solution, one denominator has to result in 0 when 6 is substituted for x. his solution for x is incorrect. when solved correctly, there are no extraneous solutions.

What is the slope-intercept formula?
Answer:
To find slope intercept, you must use the substitute term for slope, m, and then use the following equation. ↓
[tex](y = mx+b)[/tex]
Next, you want to use these terms to help you solve for b. ↓
[tex]Slope = m\\Points = x, y\\y-intercept = b[/tex]
Answer:
y=mx+b
Step-by-step explanation:
The slope intercept form is y=mx+b
M = slope
B = y-intecept
and when you substitue the numbers for the variables then you have it in slope-intercept formula

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.
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!
Answer:
Speed of the wind was
25 miles per hour.
Speed of Mighty Dragon 125 was
miles per hour.
