The area of a rectangle is 72 square metres. The length of the rectangle is twice the width. Find the width of the rectangle.
Answers
Working:
Find common factors of 72:
1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
Work out which ones multiply together to make 72 and as the question states that the length is twice the width, we need to find two numbers that multiply to make 72 and one of the numbers is double the other number.
These numbers would be 6 and 12. (6 x 12 = 72)
Therefore:
Area = 72m²
Width = 6m
Length = 12m
The parallelogram shown bellow has an area of 15 units over 2
Answers
Answer:
The value of h is [tex]\frac{5}{2}[/tex] units
Step-by-step explanation:
In any parallelogram, there are two different pair of bases b1, b2 and their corresponding heights h1, h2, where h1 ⊥ b1 and h2 ⊥ b2The area of parallelogram = b1 × h1 OR b2 × h2In the given figure
∵ Every two opposite sides of the parallelogram are equal
∴ The length of the base of the height h is 3 units
∵ The area of the parallelogram = [tex]\frac{15}{2}[/tex] units
∵ Area of parallelogram = b × h
→ Substitute the values of the area and the base in the rule above
∴ [tex]\frac{15}{2}[/tex] = 3 × h
∴ [tex]\frac{15}{2}[/tex] = 3h
→ Divide both sides by 3 to find h
∵ [tex]\frac{15}{2}[/tex] ÷ 3 = 3h ÷ 3
∴ [tex]\frac{15}{6}[/tex] = h
→ Simplify the fraction by divide up and down by 3 and switch the 2 sides
∴ h = [tex]\frac{5}{2}[/tex] units

Find the x-intercept of each line defined below and compare their values.

x intercept of line b is (1,0)
The x intercept of line A is (-6, 0) and x intercept of line B is (3, 0)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Equation of line A
y=-2/3x-4
When y=0
0=-2/3x-4
4=-2/3x
-6=x
So the x intercept for line A is -6.
Let us find equation of line B by using table
Slope = -1
Now let us find y intercept
2=-1(-1)+b
b=3
So equation is y=-x+3
Now let us find the x intercept
Put y=0
0=-x+3
x=3
(3, 0) is x intercept of line B
Hence, the x intercept of line A is (-6, 0) and x intercept of line B is (3, 0)

Write the equation of the line that is parallel to y = -2x + 4 and passes through (3, 1) in slope-intercept form.
Answers
Answer:
y = -2x + 7
Step-by-step explanation:
y = -2x + 4
Slope in above equation is -2. Parallel lines share the same slope so the new equation will also have a slope of -2.
y-intercept through point (3, 1):
y = mx + b
1 = -2(3) + b
1 = -6 + b
b = 7
Equation of line that is parallel to original:
y = mx + b
y = -2x + 7

A photographer charges a sitting fee of $15 plus $3 for each pose. Write a function to describe the situation. Find a reasonable domain and range for up to 5 poses.
Please help i really don't understand how to find the domain and range.
Answers
Answer:y=3x+15
Step-by-step explanation: (1,18), (2,21), (3,24), (4,27), (5,30) domain is your x values 1,2,3,4,5. Range is your y values. I’d assume someone wouldn’t pay $15 for 0 poses.
The function for the given situation is f(x)=15+3x and a reasonable domain and range for up to 5 poses is 5 and 30 respectively.
Given that, a photographer charges a sitting fee of $15 plus $3 for each pose.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Let the number of poses be x and the total cost be y.
The function for the given situation is y=15+3x
Thus, f(x)=15+3x
For 5 poses:
Put x=5 in the obtained function, we get
f(5)=15+3(5)
= 15+15
= 30
So, the ordered pair is (5, 30)
Hence, the function for the given situation is f(x)=15+3x and a reasonable domain and range for up to 5 poses is 5 and 30 respectively.

What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that a linear model of this situation contains the values (1, 7.3) and (9, 9.7), where [x] represents the number of weeks, and [y] represents the baby's weight, in pounds.
Assume the equation of the line in slope - intercept form is -
y = mx + c
Now -
m = (9.7 - 7.3)/(9 - 1)
m = 2.4/8
m = 0.3
The equation will be -
y = 0.3x + c
For the point - (1, 7.3), we can write -
7.3 = 0.3 x 1 + c
c = 7.3 - 0.3
c = 7
Therefore, the baby's weight at the birth of the baby was 7 pounds.

Answer:
Team score in first game < 19
Step-by-step explanation:
Point Scored in Third Game =X
Points Scored in First Game = X+6 (6 more than third game)
Points Scored in Second Game = 23
Total Points ={( First Game) +( Second Game) + (Third Game)} < 55
{ ( X+6) + (23) + (X)} < 55
X+29+X < 55
2X+29 < 55
2X< 55-29
2X < 26
X <26/2
X<13
So the point scored in First game is: (X+6)
Where X < 13
So the point in First game is < 19
