Y is directly related to X, and Y is 81 when X is 27.
The constant of variation is ___
(there are no answer choices, it's just a type in box so i need an exact answer please! :))
Answer:
y=3x or x=y/3
Step-by-step explanation:
81, y divided by 3 is equal to 27.
Evaluate the function for f(3).
f(x) = -3x - 8
Answer:
-17
Step-by-step explanation:
-3(3)-8
-9-8=-17
Answer:
f(3) = - 17
Step-by-step explanation:
To evaluate f(3), substitute x = 3 into f(x) , that is
f(3) = - 3(3) - 8 = - 9 - 8 = - 17

Answer:15
Step-by-step explanation: So we have this triangle but it's not a right triangle right so we can't just Pythagorean theorem our way out. So we have to treat the sizes as ratios. 2:12 is the ratio of the smaller triangle. 12 increases to 78 which means side 2 has to increase as well by the same ratio so 78/12 = 6.5 and 6.5*2=13 so PQ is 13 and to find NQ just add NP and PQ or 2+13 = 15
Hope it helps :)
You notice a hot air balloon descending. The elevation h (in feet) of the balloon is modeled by the function h(x)=−6x+330, where x is the time (in seconds) since you first noticed the hot air balloon. ANSWER FASTTTTT!!!
Answer:
55 secsStep-by-step explanation:
Given the elevation h (in feet) of the balloon modeled by the function h(x)=−6x+330, we can calculate the time it takes the balloon to reach the ground. The hot air balloon hits the ground at h(x) = 0.
Substitute h(x) = 0 into the modeled expression and find x as shown;
h(x)=−6x+330
0 = −6x+330
6x = 330
Divide both sides by 6
6x/6 = 330/6
x = 55 seconds
Hence the hot air balloon hits the ground after 55 seconds
. William fills 1/3 of a water bottle in 1/6 of a minute. How much time will it
take him to fill the bottle?
Answer:
1/2 minute
Step-by-step explanation:
We can use a ratio to solve
1/3 bottle 1 bottle
------------ = --------------
1/6 minute x minutes
Using cross products
1/3x = 1/6 *1
1/3 x = 1/6
Multiply each side by 3
3 * 1/3x = 3 * 1/6
x = 3/6
x = 1/2
1/2 minute
Answer:
30 seconds (1/2 minute)
Step-by-step explanation:
We are given that,
Amount of water filled in 1/6 minute = 1/3
Now, Let the time taken to fill the whole bottle with water be x
Hence,
Through the ratio method we get,
1/3:1/6 : : 1:x
Hence, we need to multiply the extremes and the means together and equalize them.
Hence,
x/3=1/6
x=(1/6)×3
x=(1/2) minute or 30 seconds

Answer:
∠ JHF = 69°
Step-by-step explanation:
Since HJ is a midline then it is parallel to EG , thus
∠ JHF and ∠ GEH are corresponding and congruent, then
7x + 62 = 79 - 10x ( add 10x to both sides )
17x + 62 = 79 ( subtract 62 from both sides )
17x = 17 ( divide both sides by 17 )
x = 1
Thus
∠ JHF = 7x + 62 = 7(1) + 62 = 7 + 62 = 69°
Answer:
7x + 62 = 180
7x= 180 - 62
x = 118 / 7
x = 16
7 × x = 7 × 16
112 + 62 = 174
Step-by-step explanation:
HOPE ITS CORRECT..

Find the measure of the indicated angle. Round to the nearest tenth of a
degree.
Step-by-step explanation:
Using trignometry, we have cosθ = Adjacent / Hypotenuse = 3/5.
Hence θ = cos-1(3/5) = 53.1° (A).

A woman sold a typewriter for Rs 13718 in the system of compound depriciation at the rate of 5 percent .If she had purchased it 3 years before how much did she pay for it by that time?
Answer:
Rs 16000
Step-by-step explanation:
Given that :
Price at which typewriter was sold = Rs 13718
Compound Depreciation rate = 5%
Time = 3 years
Amount paid for typewriter 3 years ago
Using the relation :
Final amount = Initial amount(1 - r/n)^nt
n = number of compounding times per period
Rate = r = 5% = 0.05
t = time
A = Final amount = 13718
Initial amount = original purchase price (p)
Therefore ;
13718 = p(1 - 0.05)^3
13718 = p(0.95)^3
13718 = p * 0.857375
13718 = 0.857375p
p = 13718 / 0.857375
P = Rs 16000
Amount paid at the time of purchase = 16000

A color printer prints 21 pages in 9 minutes. How many pages does it print per minute? Round your answer to the nearest hundredth.
? = pages per minute
Answer:
2.33 = x
Step-by-step explanation:
pages minutes
21 9
x 1
Cross multiply.
21×1 = 9×x
21 9x
9 9
9 cancels 9 leaving x. and 21 divided by 9 equals 2.33 pages. NB. both sides are divided by 9 because we want x by itself and what you do to one side, you have to do to the other.

The diagonals of rhombus ABCD intersect at E. Given that m∠CAD=20° and CE=4, find the m∠CDA.
Given :
The diagonals of rhombus ABCD intersect at E.
∠CAD = 20°.
To Find :
The angle ∠CDA.
Solution :
We know, diagonals of a rhombus bisects each other perpendicularly.
So, ∠DEA = 90°.
In triangle ΔEAD :
∠EAD + ∠AED + ∠EDA = 180°
20° + 90° + ∠EDA = 180°
∠EDA = 70°
Now, we know diagonal of rhombus also bisect the angle between two sides .
So, ∠CDA = 2∠EDA
∠CDA = 2×70°
∠CDA =140°
Therefore, ∠CDA is 140°.
Rosalina is driving to visit her family which live 150 km away her average speed is 60 km/h the cars tank is 20 L of fuel at the beginning of the drive and its fuel efficiency is 6 km perL fuel cost $.60 per liter how long can Roselene drive before she runs out of fuel
Answer:
With the amount of fuel she has, she can drive 120 km which will take 2 hours.
Step-by-step explanation:
You need to figure out which information is necessary for this problem and which is not.
The fuel tank has 20 L.
The car drives 6 km per L.
20 L * 6 km/L = 120 km
She can drive 120 km with the amount of fuel she has.
She is driving at 60 km/h.
speed = distance/time
time * speed = distance
time = distance/speed
time = (120 km)/(60 km/h) = 2 hours
Answer: With the amount of fuel she has, she can drive 120 km which will take 2 hours.
