Step-by-step explanation:
4) Suppose y varies inversely with the SQUARE ROOT of x.
When x = 4, y = 100.
Which variation equation you need to use? (a) y = kx or (b) y = k/x?
Find the constant of Variation (K) and then find the Variation Equation by plugging the value of k.
Answer:
Variation equation: y = k/√x
constant of variation: 200
Variation Equation by plugging the value of k: y = 200/√x
Step-by-step explanation:
If y varies inversely with the SQUARE ROOT of x, then;
y = k/√x
If x = 4, y = 100.
100 = k/√4
100 = k/2
200 = k
k = 200
Substitute into the expression
y = k/√x
y = 200/√x

a company makes carboard cylindrical boxes with a diameter of 10 inches and a height of 8 inches.how many square inches of carboard are needed for each box? Use 3.14 for pi.
Answer:
408.2sq inches
Step-by-step explanation:
Area of the cylindrical box = 2πr(r+h)
r is the radius = diameter/2
r = 10/2 = 5in
h is the height = 8in
Substitute
Area of the cylindrical box = 2(3.14)(5)(5+8)
Area of the cylindrical box = 2 * 3.14 * 5 * 13
Area of the cylindrical box = 408.2sq inches

Answer:
Perimeter of figure = 36.3
Step-by-step explanation:
We'll begin by calculating the perimeter of the rectangle. This can be obtained as follow:
Length (L) = 9
Width (W = 4
Perimeter of rectangle (Pᵣ) =?
Pᵣ = 2(L + W)
Pᵣ = 2(9 + 4)
Pᵣ = 2(13)
Pᵣ = 26
Next, we shall determine the perimeter of semi circle. This can be obtained as follow:
Diameter (d) = 4
Pi (π) = 3.14
Perimeter of semi circle (Pₛ) =?
Pₛ = ½(πd) + d
Pₛ = ½(3.14 × 4) + 4
Pₛ = ½(12.56) + 4
Pₛ = 6.28 + 4
Pₛ = 10.28
Finally, we shall determine the perimeter of the figure. This can be obtained as follow:
Perimeter of rectangle (Pᵣ) = 26
Perimeter of semi circle (Pₛ) = 10.28
Perimeter of figure =?
Perimeter of figure = Pᵣ + Pₛ
Perimeter of figure = 26 + 10.28
Perimeter of figure = 36.28 ≈ 36.3

techwiz Electronics makes a profit of $35 for each MP3 players sold and $18 for each DVD player sold. Last week, techwiz so the combined total of 128 MP3 and DVD players let X be the number of MP3 players techwiz sold last week write an expression of the combined total profit in dollars Tech whiz made from MP3 and DVD player
Answer:
128 = 35x + 18y
Step-by-step explanation:
total = 35(MP3) + 18(DVD)
128 = 35x + 18y
A parasail is at a height of 441 feet (or 0.083 miles) above sea level. The earth's radius is 3959 miles find the distance to the horizon to the parasail.
If you answer this can you please explain how to do it? I'm confused and just want to learn, but I don't understand how to solve it!
Answer:
The distance to horizon is 25.64 miles for the parasail.
Step-by-step explanation:
The distance to horizon for a given height is given as
[tex]d=\sqrt{2hR}[/tex]
Here
d is the distance to horizonh is the height of the observer which is given here as 0.083 milesR is the radius of Earth which is given as 3959 milesSo the distance becomes
[tex]d=\sqrt{2hR}\\d=\sqrt{2\times 0.083\times 3959}\\d=\sqrt{657.194}\\d=25.6357 \text{ miles}\\d=25.64\text{ miles}[/tex]
So the distance to horizon is 25.64 miles for the parasail.
The Downtown Community Barbecue served 280 dinners. A child’s plate cost $2.60 and an adult’s plate cost $9.50. A total of $1,797.50 was collected. How many of each type of plate was served?
Round answers to the nearest whole person.
child plates were served.
adult plates were served.
Answer:
the number of child plates and adults plates were served is 125 and 155 respectively
Step-by-step explanation:
Let us assume the child plate be x
And, the adult plates be y
Now according to the question
x + y = 280 .................(1)
2.60x + 9.50y = 1797.50 .............(2)
Now multiply by 2.60x in equation (1)
2.60x + 2.60y = 728
2.60x + 9.50y = 1797.50
-6.90y = -1069.50
y = 155
So, x = 280 - 155
= 125
hence, the number of child plates and adults plates were served is 125 and 155 respectively

Answer:
(C) angles A and B and those corresponding
Step-by-step explanation:
If sides are used to show similarity, at least two sides from each triangle are required. If only two sides are used, then the angle between them must also be shown to be congruent.
A -- has 2 sides, but no angles; (SS) not sufficient
B -- has 2 sides but not the angle between; (SSA) not sufficient
C -- has 2 angles; (AA) sufficient
D -- effectively, one angle; (A) not sufficient

As you can see, ABCD is similar to FECG which means its just a bigger or smaller version of the other. The sides change by a specific amount like times 2 or divided by 2
In this case abcd is 2x bigger thab fecg. You can see this by the side BC being 10 and it is the same side on the other shape being 5 so you know FECG is just ABCD x 1/2
Because of this since we know what FG is (4) on FECG we know y is 2x that side so it is 8.
please help lolllllll

Represent each of these temperatures in degrees Fahrenheit with a positive or negative number. 5 degrees above zero 3 degrees below zero 6 degrees above zero 234 2 3 4 degrees below zero Order the temperatures above from the coldest to the warmest.
Answer:
5 degrees above Zero = greater than 0 = + 5
3 degrees below Zero = less than 0 = - 3
6 degrees above Zero = greater Than 0 = + 6
2 3/4 degree below Zero = less than 0 = - 2 3/4
-3 ; - 2 3/4 ; + 5 ; + 6
Step-by-step explanation:
5 degrees above Zero = greater than 0 = + 5
3 degrees below Zero = less than 0 = - 3
6 degrees above Zero = greater Than 0 = + 6
2 3/4 degree below Zero = less than 0 = - 2 3/4
The least temperature value implies the coldest while the highest implies the warmest :
Therefore.
Least temperature = - 3 ; then - 2 3/4 ; then + 5 ; then + 6
-3 ; - 2 3/4 ; + 5 ; + 6
When confronted with an in-flight medical emergency, pilots and crew can consult staff physicians at a global response center located in Arizona. If the global response center is called, there is a 4.8 percent chance that the flight will be diverted for an immediate landing. Suppose the response center is called 8,465 times in a given year.
This question is not complete, the complete question is;
When confronted with an in-flight medical emergency, pilots and crew can consult staff physicians at a global response center located in Arizona. If the global response center is called, there is a 4.8 percent chance that the flight will be diverted for an immediate landing. Suppose the response center is called 8,465 times in a given year.
a) What is the expected number of diversions
b) What is the probability of at least 400 diversions
c) What is the probability of fewer than 450 diversions?
Answer:
a) expected number of diversions μ is 406.32
b) the probability of at least 400 diversions is 0.6368
c) the probability of fewer than 450 diversions is 0.9861
Step-by-step explanation:
Given the data in the question;
n = 8465
π = 4.8% = 0.048
so expected number of diversions μ = nπ = 8465 × 0.048 = 406.32
and
σ = √(π(1 - π ) = √(8465 × 0.048(1 - 0.048 ) = √( 406.32 × 0.952 )
σ = √386.81664
σ = 19.6677
b) the probability of at least 400 diversions
P(at least 400 diversion ) = P( X ≥ 400 )
= P( X ≥ 399.5 )
so
z = (X - μ) / σ
we substitute
z = (399.5 - 406.32 ) / 19.6677
z = -6.82 / 19.6677
z = -0.35
so
P(Z > -0.35 ) = 0.500 + p( -0.35 ≤ z ≤ 0 )
= 0.5000 + p( 0 ≤ z ≤ 0.35 )
= 0.5000 + 0.1368
= 0.6368
Therefore, the probability of at least 400 diversions is 0.6368
c) the probability of fewer than 450 diversions
P(fewer than 450 diversion ) = P( X ≤ 450 )
= P( X ≤ 449.5 )
so
z = (X - μ) / σ
we substitute
z = (449.5 - 406.32 ) / 19.6677
z = 43.18 / 19.6677
z = 2.20
so
P(Z ≤ 2.20 ) = 0.500 + p( 0 ≤ z ≤ 2.20 )
= 0.5000 + 0.4861
= 0.9861
Therefore, the probability of fewer than 450 diversions is 0.9861

Airlines monitor the causes of flights arriving late. A total of 75% of flights are late because of weather, while 35% of flights are late because of ground operations. A full 10% of flights are late because of weather and ground operations. What is the joint probability that a flight arrives late because of weather and ground operations
Answer:
36% is the joint probability that a flight arrives late because of weather and ground operations
Step-by-step explanation:
Given
% of flight late because of weather = 0.75
% of flight late because of ground operation = 0.35
% of flight late because of both weather and ground operation = 0.10
The probability of joint probability that a flight arrives late because of weather and ground operations is equal to
p (A and B) + {P(A) * P(B)}
0.10 + (0.75 * 0.35)
0.36
or 36%
Answer:36%
Step-by-step explanation:0.10 + (0.75 * 0.35)=0.36 then turn it to a percent which is 36%.

Someone please answer this
Answer:
8 m is the answer.
Step-by-step explanation:
a = ?
b (Brennan and Hannah) = 6 m
c (Jayce and Hannah) = 10 m
According to the Pythagoras theorem,
a² + b² = c²
a² + 6² = 10²
a² + 36 = 100
a² = 100 - 36
a² = 64
a = 8 m
∴ Jayce and Brennan are 8 m apart.
