a telephone booth 7 ft tall casts a shadow 20 ft long. At the same time, a nearby fire hydrant casts a shadow 8 ft long. Find the height of the fire hydrant
Answer:
2 4/5 feet
Step-by-step explanation:
let 'x' = height of fire hydrant
7/20 = x/8
cross-multiply:
20x = 56
x = 56/20 or 14/5, which is 2 4/5

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 %

Fcator: x^2-18x+72=0
*work please*
Answer:
x = 12, 6
Step-by-step explanation:
Factor using the AC method.
Consider the form x² + bx + c. Find a pair of integers whose product is c and whose sum is b . In this case, whose product is 72 and whose sum is -18.
-12, -6
Write the factored form using these integers.
(x - 12)(x - 6) = 0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
x - 12 = 0, x = 12

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

Solve the equation.
4(x + 6) = 2(2x + 12)
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
Last weekend, Mia ran 5% of a mile and Terrel ran 5/15 of a mile. Who ran a

Use the points (2, 2485.6) and (6, 1172.5) to write an equation of the line of fit in slope-intercept form. Let x be the years since 2010 and let y be the number of CDs in millions sold.
Answer:
y = -328.275x + 1829.05
Step-by-step explanation:
In this case, we need to write an equation of this form:
y = ax + b (1) a: slope b: intercept
In order to calculate the slope, we need to use the following expression:
a = y₂ - y₁ / x₂ - x₁ (2)
So, we have two points here, so, from these points we can identify each of the elements so we can determine the slope.
Point 1: (2, 2485.6)
Point 2: (6, 1172.5)
The slope of this equation will be:
a = 1172.5 - 2485.6 / 6 - 2
a = -328.275
Now that we have the slope, to get the intercept "b", we just use any of the given points, and replace in the general equation (1) to solve for b:
2485.6 = -328.275(2) + b
b = 2485.6 - 656.55
b = 1829.05
With the value of a and b, we can write the general equation of the line for this:
y = -328.275x + 1829.05Hope this helps

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.

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

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
