a varies jointly as the square root of the product of b and c. if a = 24 when b = 8 and c= 2 , find v when a = 48 and c = 4
Answer:
b = 16
Step-by-step explanation:
× stands for varies
a × √bc,
a = k√bc,
when a = 24, b = 8, c= 2
a = k√bc
24 = k√8•2
24 = k√16
24 = 4k
dividing both sides by 4
k = 24/4
k = 6
a = 6√bc (standard equation)
find b when a = 48 and c = 4
a = 6√bc
48 = 6√b•4
dividing both sides by 6
48/6 = √b•4
8 = √b•4
squaring both sides
8^2 = b•4
64 = b•4
b = 64/4
b= 16.
Thrrefore when a = 48, c = 4, b = 16.

Nick decides to play "Spin to Win" at a fundraiser event. He has a 25% chance of winning on any individual spin.
Individual spins are independent. Nick decides to play the game 10 times.
What is the probability that Nick wins at least once?
Round to 2 decimal places,
Answer:
0.015625
Step-by-step explanation:
The probability that Nick wins at least once is 2.5
What is probability?"Probability is finding out the possibilities of the occurrence of an event."
Formula to find the probability of an event:"P(A) = n(A) / n(S)
where, n(A) is the number of favorable outcomes of an event A
n(S) is the total number of outcomes for an experiment"
What is percent?"It is a number that can be expressed as a fraction of 100."
For given example,
Nick has a 25 percent chance of winning on any individual.
This means, his chances of winning on any individual spin are 0.25
Individual spins are independent and Nick decides to play the game 10 times.
So the probability that Nick wins at least once is 10 × 0.25 = 2.5
Therefore, the probability that Nick wins at least once is 2.5

with three cans of paint u can paint 2 walls with 2 layers. How many cans do u need to paint 10 walls with 3 layers?
Answer:
22.5 cans of paint
Step-by-step explanation:
[tex]n=3*10*\frac{3}{2*2} =30*\frac{3}{4} =22.5 cans[/tex]
Answer:
You need 22.5 cans of paint to paint 10 walls with 3 layers.
Step-by-step explanation:
[tex]\frac{3}{2*2}[/tex] = 0.75 (Represents how many cans of paint it takes to paint 1 wall with 1 layer)
0.75 * 10 * 3 = 7.5 * 3 = 22.5 (The number of paint needed for 1 wall with 1 layer multiplied by 10 walls with 3 layers to get the total amount of paint needed)

A mountain bike originally priced at $960.00 is up for sale at a discount of 14%. What is the price of the mountain bike after the discount?
Answer:
$825.60
Step-by-step explanation:
Since the price of it is $960.00, it means that it's 100%.
100% = 960
1% = 960 ÷ 100 = 9.6
14% = 9.6 x 14 = 134.40
Since they asked for after the discount, deduct the price of the discount with the original price.
Mountain bike after 14% discount =
960 - 134.40 = 825.60
1. Maggie keeps track of daily bird sightings. The table below shows the number and type of swans that were seen in one day. What percent of the swans were mute swans? Round your answer to the nearest tenth of a percent.
Answer:
hello! i just did this problem and the answer is 12.2%
Step-by-step explanation:
first we need to add all of the swans together, then from there you take the amount of mute swans and divide it by the sum of all the swans! finally, multiply by 100 to convert into a percent and round it to 12.2%
hope this helped plz give me brainliest! <3
The solution is 12.2 %
The percentage of mute swans is given by the equation A = 12.2 %
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the percentage of mute swans be represented as A
Now , the equation will be
Let the total number of swans be S
The number of mute swans = 5 swans
The number of Trumpeter swans = 34 swans
The number of Tundra swans = 2 swans
So , the total number of swans S = 5 + 34 + 2 = 41 swans
And , the percentage of mute swans A = ( number of mute swans / total number of swans S ) x 100
Substituting the values in the equation , we get
The percentage of mute swans A = ( 5/41 ) x 100
On simplifying the equation , we get
The percentage of mute swans A = 0.1219 x 100
The percentage of mute swans A = 12.19
The percentage of mute swans A = 12.2 %
Therefore , the value of A is 12.2 %
Hence , the percentage is 12.2 %

Option c = [tex]\sqrt[9]{3}[/tex]
Step-by-step explanation:
One side = 18
Bottom side = 18 (equalateral triangle)
we can use phytagorues theorum:
a = the altitude (unknown)
b= one side (half of the bottom side) = 18/2 = 9
c = hypothenus = 18 (given)
a^2 + b^2 = c^2
a^2 + 9^2 = 18^2
a^2 = 18^2 - 9^2
a^2 = 243

if a ball is rolling down hill and accelerating at a rate of 2m/s^2 because of a 2N net force. What is the mass of the ball?
Answer:
1kgStep-by-step explanation:
According to Newton's second law
Force = mass * acceleration
Given
Force = 2N
acceleration = 2m/s^2
Mass =Force/Acceleration
Mass = 2/2
Mass =1kg
Hence the mass of the ball is 1kg
a line with a slope of 1 passes through the point (-7,-5). what is its equation in slope- intercept form? (y=mx+b)
Answer:
y = x + 2Step-by-step explanation:
Equation of line with a given slope of a and containing a given point (x₀, y₀):
y - y₀ = a(x - x₀)
a = 1, x₀ = -7, y₀ = -5
Therefore:
y - (-5) = 1(x - (-7))
y + 5 = x + 7
y = x + 7 - 5
y = x + 2

Answer:
0
Step-by-step explanation:
Answer:
All Real Numbers
Step-by-step explanation:
[tex]4(x + 6) = 2(2x + 12)[/tex]
divide both sides by 2
[tex]2(x + 6) = 2x + 12[/tex]
[tex]2x + 12 = 2x + 12[/tex]
this is enough to prove that it's all real numbers, but it can be simplified even more
[tex]2x=2x[/tex]
subtract 2x from both sides
[tex]0=0[/tex]
0 will always equal 0, so x is all real numbers
