Answer:
x = 19.6
Step-by-step explanation:
By applying cosine rule in ΔBCD,
cos(30)° = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{BC}{BD}[/tex]
[tex]\frac{\sqrt{3}}{2}=\frac{BC}{16}[/tex]
BC = [tex]8\sqrt{3}[/tex]
Now, by applying sine rule in ΔBAC,
sin(45)° = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{AB}{BC}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{x}{8\sqrt{3}}[/tex]
x = [tex]8\sqrt{6}[/tex]
x = 19.59
x ≈ 19.6
Nolan has 4 times as many pens as Fiona, and Fiona has 6 times as many pencils as Nolan. If Nolan has a total of 23 pens and pencils, and so does Fiona, which of these is a number of pens or a number of pencils that either Nolan or Fiona has?
Nolan has 20 pens and 3 pencils, while Fiona has 5 pens and 18 pencils.
Amount determinationGiven that Nolan has 4 times as many pens as Fiona, and Fiona has 6 times as many pencils as Nolan, to determine, if Nolan has a total of 23 pens and pencils, and so does Fiona, the number of pens and pencils that either Nolan or Fiona has, the following calculation must be performed:
Pen = APencil = BN = 14A + 9B = 23 /// F = 3.5 + 19.5N = 12A + 11B = 23 /// F = 3A + 20BN = 20 A + 3 B = 23 /// F = 5 A + 18 B20 / 4 = 518 / 6 = 3Therefore, Nolan has 20 pens and 3 pencils, while Fiona has 5 pens and 18 pencils.

PLEASE PLEASE HELP, I AM TIMED! What is the equation to the function? Explain.
Step-by-step explanation:
General equation: y = 2 + c/(x - 1)
When x = 4, y = 4.
=> (4) = 2 + c/(4 - 1), c = 6.
Hence the equation is y = 2 + 6/(x - 1).

Answer: n = 0
Step-by-step explanation: Let's solve for n, according to the linear equation given, this way:
10n + 0.3 = 0.1n + 0.3
10n - 0.1n = 0.3 - 0.3 (Like terms)
9.9n = 0

When Zakir threw a beach ball to his friend, its horizontal velocity changed as it traveled through the air. The relationship between the elapsed time, t, in seconds, since Zakir threw the ball, and its horizontal velocity, V(t), in cm/s is modeled by the following function: V(t) = 4 x(5/8)^t Complete the following sentence about the rate of change of the horizontal velocity of the ball. Every second, the horizontal velocity of the ball grows/shrinks v by a factor of Report a problem Stuck? Watch a video or use a hint.
Answer:
5/8
Step-by-step explanation:
For khan the full correct answer is Shrinks by 5/8.
Every second, the horizontal velocity of the ball shrinks v by a factor of 5/8.
What is a Function?A function is a law that relates a dependent and an independent variable.
The horizontal velocity in relation with elapse time is given by
[tex]\rm V(t) = 4 x(\dfrac{5}{8})^t[/tex]
The rate of change of the the horizontal velocity of the ball is given by [tex]\rm (\dfrac{5}{8})^t[/tex]

A cyclist is travelling at an average speed of 15km/HR. How long will it take to travel a distance of 52 1/2km
Answer:
3.5hour
Step-by-step explanation:
Average speed = Distance/Time
Given
Distance = 52 1/2 km
Speed = 15km/hr
Required
Time
Substitute the given values in the formula
Time = (52 1/2)/15
Time= 105/2 * 1/15
Time = 105/30
Time = 3.5hour
hence it will take 3.5hr to travel a distance of 52 1/2km

ben earns 140 dollars by selling 70 hot dogs how much does ben need to sell to get 300 dollars
Answer:
Ben would earn $280 by selling 140 hot dogs.
Step-by-step explanation:
You do this by multiplying 140 x 2,
If this equals 280, then you would do 70 x 2 to make it even
If this equals 140,
Ben will sell 140 hotdogs, and make $280
Answer:
150 hot dogs
Step-by-step explanation:
1 hot dog is $2 so 140 hot dogs=$280 so if u add 10 hot dogs that would be $20 so $280+$20=$300 which is equal to 150 hotdogs
What is the first step you would take to solve the equation 5x - 12 = -20?
Divide 5x and -20 by 5.
Add 20 to both sides.
multiply 12 by .
Add 12 to both sides.
Answer:
The first step would be to add twelve to both sides
Step-by-step explanation:
Answer:
add 12 to both sides
Step-by-step explanation:
What we want to do, is to isolate the variable and the numbers on different sides.
if we divide 5x and -20 by 5, what about -12? It's part of the equation too.
If we add 20 to both sides, the numbers and the variable are on the same side, so we'll need to subtract it back off to isolate both.
If we multiply 12 by (what was there) it won't be isolating the variable or numbers. We'll just be increasing the value of the terms already there.
However, if we add 12 to both sides, we'll be isolating both the variable AND the numbers onto different sides.
therefore, add 12 to both sides.
Hope this helps!
