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 equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The present age of the boy = 20 years
Three years ago, the boy's age would have been:
20 - 3 = 17
Hence , the boy was 17 years old three years ago.

What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (2, 2) and (5, 8).
Now,
Since, The equation for the line is,
y = ax + b
Put x = 2, y = 2
2 = 2a + b .. i)
Put a = 5, y = 8;
8 = 5a + b . (ii)
Subtract (ii) from (i);
3a = 6
a = 2
And, 8 = 5a + b
8 = 5 x 2 + b
8 = 10 + b
b = - 2
Hence, We get;
⇒ y = 2x - 2

S10= -341
Step-by-step explanation:
1,-2,4,-8,16,.......
Sum of first 10 terms of geometric sequence
Sn=a(r^n-1)/r-1
where, a= first term
n= number of terms
r=common ratio
common ratio (r)= second term/first term
r=-2/1
r=-2
a=first term
a=1
n= number of terms
n=10
S10=1[(-2)^10-1]/-2-1
S10=(1024-1)/-3
S10=1023/-3

It would be easier to explain if the triangle and the parallelogram have their points named.
Some first hints: The area of a tri
angle equals to 1/2 of height times length of corresponding base side. The area of a parallelogram equals to height times the corresponding base side. in addition, in a parallelogram, two opposing side have the exact same length.
Since then, we can write the area of the triangle as 1/2× h× 18= 9×h
we can write the area of the parallelogram as : 18×h
Since then, we can write the area of the compound as 9×h + 18×h= 27h.
Voila. I gues you can figure out the rest. Please ask more if you have trouble with this

PLEASE HELP ASAP NO LINKS OR WILL BE REPORTED! 1. In the figure below, a line intersects two parallel lines. Fill in the missing angles. a /b d e 42° C f f g (a)
Answer:
<a=138°
<b=42°
<c=138°
<d=138°
<e=42°
<f=42°
Step-by-step explanation:
<a is supplementary with the 42° angle:
<a=180°-42°=138°
<b and the 42° are vertical angles, so:
<b=42°
<c and <a are also vertical angles so:
<c=<a=138°
<d and <a are corresponding angles, so:
<d=<a=138°
<e and <b are corresponding angles, so:
<e=<b=42°
<f and the 42° angle are corresponding angles, so:
<f=42°
<g and <c are corresponding angles, so:
<g=<c=138°

What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as A
Now , the value of A is
f ( x ) = 4x + 4
On simplifying , we get
when x = 2
C ( 2 ) = 4 ( 2 ) + 4
C ( 2 ) = 8 + 4
C ( 2 ) = 12

Answer:
sqrt( 3V /(pi h)) =r
Step-by-step explanation:
V = 1/3 pi r^2 h
Multiply each side by 3
3*V = 3*1/3 pi r^2 h
3V = pi r^2 h
Divide each side by pi h
3V / (pi h) = pi r^2 h / ( pi h)
3V /(pi h) = r^2
Take the square root of each side
sqrt( 3V /(pi h)) = sqrt(r^2)
sqrt( 3V /(pi h)) =r

Answer:
Cylinder A: 3.58 m^3, cylinder B: 8.72 m^3, cylinder B has the greater volume
Step-by-step explanation:
Volume of a cylinder [tex]V=\pi r^2h[/tex] r is the radius, h is the height.
Cylinder A: The circumference is given, C = 3. Circumference is found by the formula [tex]C=2 \pi r[/tex]. Replace C with 3 and solve for r so it can be used in the volume formula.
[tex]3=2\pi r\\3=2(3.14)r\\3=6.28r\\r=3 \div 6.28 \approx .4777[/tex]
Volume: [tex]V=(3.14)(.4777)^2(5) \approx 3.58[/tex] cubic meters
Cylinder B:
[tex]C=2\pi r\\5=2(3.14)r\\r=5 \div 6.28 \approx .7962\\\\V=\pi r^2h\\ V=(3.14)(.7962)^2(3) \approx 8.72[/tex] cubic meters

The manufacturer of running shoes conducted a study on its newly developed jogging shoe. Listed are the type and frequency of the nonconformities and failures found. A Pareto chart to show the major problem areas is given below. (Round your answers to 1 decimal place.) Type of Nonconformity Frequency Type of Nonconformity Frequency Sole separation 36 Lace breakage 13 Heel separation 92 Eyelet failure 8 Sole penetration 60 Other 16
Answer: Hi your question is poorly structured I believe your question is construct a pareto chart to show the major problem areas
answer : attached below is the pareto chart.
Step-by-step explanation:
Rearranged table starting from highest frequency
The type of Nonconformity Frequency Percentage
Heel separation 92 40.89
sole penetration 60 26.67
Sole separation 36 16
Other 16 7.11
Lace breakage 13 5.8
Eyelet failure 8 3.5
Total = 36 + 13 + 92 + 8 + 60 + 16 = 225
Next step : determine the percentages of the various Nonconformity
sole separation = 36 / 225 ) * 100 = 16%
lace breakage = ( 13/225 ) * 100 = 5.8% = 6%
Heel separation = ( 92/225 ) * 100 = 40.89% = 41%
Eyelet Failure = ( 8 /225 ) * 100 = 3.5% = 4%
sole penetration = ( 60 / 225 ) * 100 = 26.67% = 27%
other = ( 16 / 225 ) * 100 = 7.11% = 7%
