Answer: 9
Step-by-step explanation:
the formula for the area of a triangle is a=bh/2, since the area is 54 we would need to multiply it by 2 which would be 108 to reverse the division. then we would divide it by 12 which would be 9 to reverse the multiplication.
Answer:
[tex]beinggreat78~here.[/tex]
The base is 9
Multiply 9 by 12, which is 108, and divide by 12, which is a way of giving you 9.

Nicole and Ian generate two patterns. Nicole uses the rule multiply by 3 then add 2 starting with 1. Ian uses the rule add 1/2 then multiply by 2 starting from 0. Complete the table to show the numbers in each pattern. Then create the ordered pairs.
Answer:
Nicole: 1, 5, 17, 53, 161, 485
Ian: 0, 1, 3, 7, 15, 31
Pairs: 1,0- 5,1- 17,3- 53,7- 161,15- 485,31
Step-by-step explanation:
The coordinate pairs of Nicole and Ian's rule are (5,1),(17,3),(53,5),(161,10),(485,20)
What is coordinate?A coordinate is a system that uses one or more number to show the position of the points. It is in (x, y) form where x shows value on x axis and y shows value on y-axis.
How to determine coordinates?We have been given that Nicole's rule is multiplied by 3 then add 2 starting with 1.
Values of Nicole's rule are 5,17,53,161,485.
Ian's rule is given as add 1/2 then multiply y 2 starting from 0. The values will be:
1,3,5,10,20.
Hence the coordinates are (5,1),(17,3),(53,5)(161,10),(485,20).

what are the angles of a triangle with 73, x, x-11?
Answer:
The angles of the triangle are 73, 59, and 48
Step-by-step explanation:
The sum of a triangle's angles must always add up to 180
In order to find out the measure of x we must make an equation where 180=the sum of the angles
180=2x+62
We got the 2x and the 62 from combining like terms
x+x=2x
73-11=62
Now we simply use algebra and try to solo out the x
First, subtract 62 from both sides
118=2x
Then, divide both sides by 2
59=x
x=59
Then plug in 59 with x and this gives you
73, 59, and 48 which all together add up to 180

Answer:
[tex]y = 2(x + 3) ^{2} - 1[/tex]
should be it. good luck!
Answer: y = 2 (x+3)^(2) -1
Step-by-step explanation:
y=mx+b formula
inside parentheses as (x+n) or (x-n) brings the graphed line left or right on the x-axis (+ is left, - is right). thus, we have (x+3), which is then squared to create the u shaped curve.
to bring the point curve to a -1 in the y-axis (-3,-1), a -1 is added to the end, outside of the parentheses. thus we now have [(x+3)^2] -1
to narrow the curve, the part parentheses is multiplied, here by two. thus, the final answer is y=[(x+3)^2]-1

Answer:
πr + 2r
Step-by-step explanation:
Perimeter of Semicircle
The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.
Step-by-step explanation:
1. d = 22mm
circumference = πr + d
= 22/7 × 11 + 22
= 56.57 mm
2. r = 4 inches
circumference = πr + d
= 22/7 × 4 + 8
= 20.57 Inches
3. d = 10 yards
circumference = πr+d
= 22/7 × 5 + 10

The origin is located in Quadrant |.
True
The ordered pair (2,-5.2) is located in Quadrants IV.
To Plot points in Quadrant |||, move left and down from the origin.
Step-by-step explanation:
The ordered pair (2,-5.2) is located in Quadrants IV. True
True, because Quadrants IV contains order pairs of the form of (+,-)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Quadrant || contains ordered pairs of the form (Positive number, Negative number False
False, because Quadrant || contains order pairs of the form (-,+)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The point (-6,0) is located on the y-axis False
False, the abscissa or x-coordinate is −6 and the ordinate or y-coordinate is 0. We know, any point on the x-axis has the form (a,0) and any point on the y-axis has the form (0,a), where a is any number.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The origin is located in Quadrant |. False
Origin always in the middle.
We know, the origin is the point of intersection of the x-axis and the y-axis. That is, when x=0 and y=0, we get the origin.
