Approximately 1 gallon of 4 buckets will be needed to paint 90ft²of fences.
Formula used: N = kA / p
Given information:
N = 3 (buckets)k = constantA = area that is72p = components of a bucket (1 gallon in this case)So,
Determine k.
This is something you must work out with the units when solving for k.
3 buckets = k × 72 ft^2/1 gallon3 buckets × 1 gallon = k × 72 ft²3 bucket gallons / 72 ft² = k k = 1/24 bucket gallons / ft² = kThen, we get:
k = 0.04166666666 × bucket gallons / ft² = kNow, solve for 90 ft² as follows:
n = k × Area / pp = 1k = 0.04166666Area = 90So,
n = 0.041666666 × 90 / 1n = 3.75 bucketsAfter rounding off, the answer will be 4 buckets of 1-gallon.
Therefore, approximately 1 gallon of 4 buckets will be needed to paint 90ft²of fences.

How to find compound interest?He grand parents wanted to invest in a bank.
They have $35,000 they are willing to invest for 6 years.
The interest rate is 4% and compounded quarterly.
The amount they will have in there account after 6 years can be calculated as follows:
using compound interest formula,
A = p(1 + r/n)ⁿᵇ
Where
p = principalr = interest rateb = time in yearsn = compoundTherefore,
p = 35000
r = 4% = 0.04
n = 4
b = 6
Amount = 35,000(1 + 0.04 / 4)⁴ˣ⁶
Amount = 35,000(1.01)²⁴

2x + kx = m solve for x
Answer:
x=m/2+k , k≠-2
Step-by-step explanation:
2x+kx=m
Factor out x from the expression:
(2+k)x=m
Assume 2+k≠0 and divide both sides of the equation by 2+k:
x=m/2k , 2+k≠0
Rewrite the restriction:
x=m/2+k≠-2
Solution:
x=m/2+k , k≠-2
The value of x in the given expression is x = m / (k+2)
What is an expression?An expression is a mathematical statement containing variables, numerical, and they are related by at least one mathematical operation.
Given an expression, 2x + kx = m
We are asked to rearrange the values and find the value of x.
Therefore,
2x + kx = m
Since, two terms have same variable, therefore, taking x common from both,
x(2+k) = m
x(k+2) = m
Now, transpose (k+2) to right side, we get,
x = m / (k+2)
Hence, we get the value of x as, x = m / (k+2)

The answer to this question is (gof)(x)=2x+7
According to question:
Given: f(x)=4 x, g(x)=1/2 x+7,h(x)=-2 x+4
(gof)(x)=g(f(x))=g(4x)=1/2×4x+7=2x+7(fog)(x)=f(g(x))=f(x/2+7)=4×(x/2+7)=2x+28We always simplify everything in brackets first using BODMAS. Therefore, in order to compute f(g(x)), g(x) must first be calculated and then substituted within f(x). Similar to this, in order to determine g(f(x)), f(x) must first be computed and then substituted in g(x). In other words, the sequence is important when locating the composite functions. It implies that g(f(x)) and f(g(x)) may not be equal. The following procedures are used to obtain the composite function f(g(a)) for any two functions f(x) and g(x).
By changing x = a in g, find g(a) (x).

According to the empirical rule, ________ will be within two standard deviations of the mean.
According to the empirical rule, 95% will be within two standard deviations of the mean.
The empirical rule, also referred to as the three-sigma rule or 68-95-99.7 rule, is a statistical rule which states that for a normal distribution, almost all observed data will fall within three standard deviations (denoted by σ) of the mean or average (denoted by µ).
Under this rule, 68% of the data falls within one standard deviation, 95% percent within two standard deviations, and 99.7% within three standard deviations from the mean. Three-sigma limits that follow the empirical rule are used to set the upper and lower control limits in statistical quality control charts and in risk analysis such as VaR.
The empirical rule is used often in statistics for forecasting final outcomes. After calculating the standard deviation and before collecting exact data, this rule can be used as a rough estimate of the outcome of the impending data to be collected and analyzed.

Answer: (10, 8)
Step-by-step explanation:
To solve a substitution question, you have to make sure either x or y is alone on the other side of equal sign.
-x + y = -2
^^^this becomes y = -2 + x
Now, since you know what "y" is, you simply replace "y" with our new equation in the other equation.
-x - 2(-2+x) = -26
Then, you do order of operations to get the answer.
First, do distributive property.
-x + 4 - 2x = -26
Next, solve the equation.
-3x + 4 = -26
-3x = -30
x = 10
Since you found what "x" is, you substitute "x" and in one of your equations to find "y", it doesn't matter which one.
-(10) + y = -2
-10 + y = -2
y = 8
Finally, after you got "x" which is 10, and "y" which is 8, you put them in an ordered pair (x, y) which is (10, 8).

2. x = 8; m<GDH = 126°; m<FDH = 200°; m<FDE = 137°
How to Find the Measures of Angles?1. Since QS bisects angle PQT, therefore:
measure of angle PQS = measure of angle SQT
Given:
m<SQT = 8x - 25
m<PQT = 9x + 34
m<SQR = 112°
Thus:
m<PQT = 2(m<SQT)
Substitute
9x + 34 = 2(8x - 25)
9x + 34 = 16x - 50
9x - 16x = -34 - 50
-7x = -84
x = 12
m<PQS = m<SQT = 8x - 25
Plug in the value of x
m<PQS = 8x - 25 = 8(12) - 25
m<PQS = 71°
m<PQT = 9x + 34 = 9(12) + 34
m<PQT = 142°
m<TQR = m<SQR - m<SQT [angle addition theorem]
m<TQR = 112 - 71
m<TQR = 41°
2. Given:
m<GDE = 8x - 1
m<EDH = 6x + 15
m<CDF = 43
m<GDE = m<EDH [reason: DE bisects GDH]
Substitute
8x - 1 = 6x + 15
8x - 6x = 1 + 15
2x = 16
2x/2 = 16/2
x = 8
m<GDH = 2(m<GDE)
m<GDH = 2(8x - 1)
m<GDH = 16x - 2 = 16(8) - 2
m<GDH = 126°
m<FDG = 180 - m<CDF - m<GDE
m<FDG = 180 - 43 - (8x - 1)
m<FDG = 180 - 43 - (8(8) - 1)
m<FDG = 180 - 43 - 63
m<FDG = 74°
m<FDH = m<FDG + m<GDH
m<FDH = 74 + 126
m<FDH = 200°
m<FDE = m<FDG + m<GDE
m<FDE = 74 + 63

f(x)=x+3, g(x)=x-5
A composite function exists as a function that depends on another function. The value of f(g(x)) = x-8 and g(f(x)) = x-2.
What is meant by composition function?In mathematics, function composition exists as an operation ∘ that takes two functions f and g, and has a function h = g ∘ f such that h(x) = g. In this operation, the function g exists used to the result of applying the function f to x.
Function composition is a mathematical procedure where two functions, f, and g, are taken and a function, h = g ∘ f, is produced such that h(x) = g(f(x)). The function g exists used in this operation on the outcome of applying the function f to x.
Let the two functions be f(x) = x+3 and g(x) = x-5
f(g(x)) = f(x-5)
simplifying the above equation, we get
f(x-5) = x-5+3
f(g(x)) = x-8
g(f(x)) = g(x+3)
simplifying th above equation, we get
g(x+3) = x+3-5
g(x+3) = x-2
Therefore, the value of f(g(x)) = x-8 and g(f(x)) = x-2.

The length of a road on the map is 4 cm.
What is the length of the road in real life?
Give your answer in kilometres.
According to the solving the length of the road in real life will be = 8 km.
What is a map scale?The relationship (or ratio) between the distance on a map and the comparable distance on the ground is referred to as map scale. For example, on a 1:100000 scale map, 1cm on the map represents 1km on the ground.
Why is a scale used on maps?You've probably seen maps with just a scale bar representing equal sections, each marked with kilometres or miles. These divisions have been used to calculate ground distance on a map. In other words, a map scale specifies the relationship between the map and indeed the entire or a portion of the earth's surface depicted on it.
According to the given data:scale on a map is 1 : 200,000.
= 1 : (200,000/(100*1000))
= 1:2
= 2km
So,
length of a road on the map is 4 cm.
= 4*2
= 8km

Trapezoid WXYZ has vertices at W(–5, –1), X(–3, –1), Y(–2, 1), and Z(–6, 1). Trapezoid WXYZ is translated so that the coordinates of Y' are (0, 3). What will be the coordinates for W′?
Solution :
the coordinates for W′ = (-1,3)
Trapezoid :
A trapezoid is necessarily a convex quadrilateral in Euclidean geometry. The parallel sides are called the bases of the trapezoid. The other two sides are called the legs (or the lateral sides) if they are not parallel; otherwise, the trapezoid is a parallelogram, and there are two pairs of bases). A scalene trapezoid is a trapezoid with no sides of equal measure
Y = (-2,1)
Y' = (0,3)
Unit shift for Y to Y'
By distance formula :
yy' = [tex]\sqrt{{(x2-x1})^{2} +( y2-y1)^{2} }\\[/tex]
= root of (2)^2 +(2^2)
= root of 4+4
Root of 16
= root of 4
Unit shift for Y to Y' = 4
then
w = (-5,-1)
shift by adding 4
W' = (-5+4, -1+4)
W' = (-1,3)
the coordinates for W′ = (-1,3)
