To determine what is equivalent to 3×7.2, simply multiply 3 by 7.2 to get 21.6.
Raul used the model to calculate 3×7.2. To find what is equivalent to 3×7.2, we can multiply the two numbers directly. Multiplying 3 by 7.2 gives us 21.6, so 3×7.2 is equivalent to 21.6.
The question seems to be asking for a calculation based on a model, but without the specifics of the model, the best we can do is a straightforward multiplication. Remember, when multiplying by a whole number and a decimal, you multiply as if they were both whole numbers and then place the decimal in the product based on the number of decimal places in the original numbers.

You must use Pythagorean theorem, which is [tex]a^{2} +b^{2} =c^{2}[/tex]
a and b are both legs (the two legs are the sides that form a perpendicular right angle) while c is the hypotenuse (side opposite the right angle)
In this case...
a = y
b = 8
c = 12
^^^Plug these numbers into Pythagorean theorem
[tex]y^{2} +8^{2} =12^{2}[/tex]
Simplify as much as possible
[tex]y^{2}[/tex] + 64 = 144
Isolate y by subtracting 64 to both sides
[tex]y^{2}[/tex] + (64 - 64) = 144 - 64
[tex]y^{2}[/tex] = 80
Further isolate y by taking the square root of both sides. This will take away the square from the left side
y = [tex]\sqrt{80}[/tex]
[tex]\sqrt{80}[/tex] <<< Can be further simplified
4√5 = y

Simplify 8-{x-(5+x)}
Answer: 13
Step-by-step explanation: 1st - Distribute the -1 through to the x + -1*(5+x) first: 8 + -1*[x + -1*(5+x)] = 8 + [-1*x + -1*-1*(5+x)]
= 8 + [-x + -1*-1 *(5+x)]
Multiply the two -1s that are in front of the (5+x). Negative x Negative = positive
Minus the paranthesis
Do PEDMAS
8 + [-x + 5 + x] <- -x +x = 0
= 8 + [0 + 5] <- 0 and 5 are like terms and will be combined
= 8 + 5 = 13
Adam is 12 years older than his sister Liz. Four years ago Adam was 4 times older than his sister. How old is each now?
His sister is 8 and he is 20.
let's say z represents liz. we can make an equation where z+12=4z.
Solve for that and z is equal to 4. Now that was 4 years ago. She should be 8 now?
I hope this is correct because my brain isn't doing so well today.
Answer:
Adam is 20 years old and Liz is 8 years old.
Step-by-step explanation:
Let present age of Adam = x years
Let present age of Liz = y years
Now we will make the equations.
x = y + 12 -------------(1)
For second equation
( x-4) = (y-4) × 4
x-4 = 4y - 16
x = 4y + 4 - 16
x = 4y - 12 -----------------(2)
By substitution method, we substitute the value of x from equations (1) to equation (2).
y + 12 = 4y - 12
y - 4y + 12 = -12
-3y = -12 -12
3y = 24
y = 8
Now we put the value of y in equation (1)
x = 8 + 12 = 20
Therefore, Adam is 20 years old and Liz is 8 years old.

Is 3i a complex number
Remember that a complex number has the form a + bi. You need to figure out what a and b need to be. Since −3i is an imaginary number, it is the imaginary part (bi) of the complex number a + bi. This imaginary number has no real parts, so the value of a is 0.
ANSWER
Yes
EXPLANATION
The number
[tex]3i[/tex]
can be rewritten as
[tex]0 + 3i[/tex]This is of ty form
[tex]z = a + bi[/tex]
where 0 is the real part and 3i is the imaginary or complex part.
[tex]3i[/tex]
is therefore a complex number. It is purely imaginary because the real part is zero.

Estimate the sum by first rounding each mixed number to the nearest whole number and then adding
3 8/9 + 2 5/6
For this case we have:
[tex]3 \frac {8} {9} = \frac {27 + 8} {9} = \frac {35} {9} = 3.8888[/tex]
Round the nearest whole, that is, to 4.
[tex]2 \frac {5} {6} = \frac {12 + 5} {6} = \frac {17} {6} = 2.8333[/tex]
Round the nearest whole, that is, to 3.
So, rewriting we have:
[tex]4 + 3 = 7[/tex]
ANswer:
[tex]3 \frac {8} {9} +2 \frac {5} {6} = 7[/tex]
right triangle LMM has vertices L(7,-3), M(7,-8), and N(10,-8). the triangle is translated on the coordinate plane so the coordinates of L’ are (-1,8). which rule was used to translate the image
Answer:
(x, y ) → (x - 8, y + 11)
Step-by-step explanation:
L(7, - 3) and L'(- 1, 8)
The x-coordinate 7 → - 1 , that is a shift of - 8
The y- coordinate - 3 → 8, that is a shift of + 11
The rule to translate LMN → L'M'N' is
(x, y ) → (x - 8, y + 11 )

Answer:
The area of rectangle C is 2
Step-by-step explanation:
Using a scale factor of [tex]\frac{1}{5}[/tex] yields the side lengths of 1 and 2
[tex](1)(2)=2[/tex]
Answer:
2 square units
Step-by-step explanation:
hello
The scale factor or linear scale factor is the ratio between the length of the same side in two similar figures.
in the graph we have a rectangle with width 5 units and long 10 units, and we know the scale factor is 1/5
[tex]S_{f}=\frac{width(C)}{width(B)}\\ \\Width(B)*S_{f} =width(C)=5 units *\frac{1}{5} \\\\Width(C) =\frac{5}{5} units =1 unit[/tex]
[tex]S_{f} =\frac{length (C)}{length(B)} \\\\\\length(C)=length(B)*S_{f}\\length(C)=(10*\frac{1}{5})[/tex]
[tex]Length(C) =2 units\\\\ the area is A=w*l\\\\A=1 unit * 2 units\\\\\\[/tex]
A=2 square units

line q and line M are cut by transversal lines J&K the lines and the measures of some of the angles created by the intersections of the lines are shown in the diagram below. What is the measure of angle 5?
The angle of 110° and the angle labelled as 1 form 180°, so we have
[tex]<1> = 180-110=70[/tex]
The same holds for the angle labelled 2 and the 115° angle:
[tex]<2> = 180-115=65[/tex]
Angle 1, 2 and 7 are the interior angles of a triangle, so they sum to 180. We can deduce
[tex]<7> = 180-70-65=45[/tex]
Angles 5 and 7 are corresponding angles, so they have the same measure.
Zula has a conical bird feeder with a volume of 64.3 cubic centimeters and a height of 7 centimeters. Which equation can be used to find the area of the circular lid needed to cover the bird feeder?
Answer:
[tex]64.3=\frac{1}{3}(B)(7)[/tex]
Step-by-step explanation:
we know that
The volume of a cone (bird feeder) is equal to
[tex]V=\frac{1}{3}Bh[/tex]
where
B is the area of the base
h is the height of the cone
In this problem we have
[tex]V=64.3\ cm^{3}[/tex]

[tex]64.3=\frac{1}{3}(B)(7)[/tex]
[tex]192.9=(B)(7)[/tex]
[tex]B=192.9/(7)=27.56\ cm^{2}[/tex]
The equation that can be used to determine the area of the circular lid needed to cover the bird feeder is 64.3 = 1/3 x b x 7.
What is the equation?A cone is a three-dimensional shape that consists of a circular base and a vertex.
Volume of a cone = 1/3πr²h
Area of a circle = πr²
πr = 64.3 = 1/3 x b x 7

Give an example of a function with a domain of (-infinity,0)
You may consider a function with domain [tex](0,\infty)[/tex] and switch [tex]x\mapsto -x[/tex]
For example, we know that
[tex]y=\log(x)[/tex]
can only be evaluated for positive values of the argument. This means that
[tex]y=\log(-x)[/tex]
can also be evaluated only for positive values of the argument, i.e.

652 ft²Step-by-step explanation:
Look at the picture.
It's a net of right rectangular prism.
We have three pairs of rectangles:
7ft × 8ft
7ft × 18ft
8ft × 18ft
The formula of an area of a rectangle l × w:
A = lw
Calculate the areas:
A₁ = (7)(8) = 56 ft²
A₂ = (7)(18) = 126 ft²
A₃ = (8)(18) = 144 ft²
The Surface Area :
S.A. = 2A₁ + 2A₂ + 2A₃
Substitute:
S.A. = 2(56) + 2(126) + 2(144) = 652 ft²
Which of the following could be the graph of this equation?
Answer: OPTION C.
Step-by-step explanation:
Given a function f(x), the range of the inverse of f(x) will be the domain of the function f(x) and the range of the domain of f(x) will be the range of the inverse function.
For example, if the point (2,1) belongs to f(x), then the point (1,2) belongs to the inverse of f(x).
Observe that in the graph of the function f(x) the point (-3,1) belongs to the function, then the point (1,-3) must belong to the inverse function.
Therefore, you need to search the option that shown the graph wich contains the point (1,-3).
Observe that the Domain f(x) is (-∞,0) then the range of the inverse function must be (-∞,0).
This is the graph of the option C.

B.
0.2525
C.
0.8125
D.
1.0000
Answer:
C. 0.8125
Step-by-step explanation:
The probability to sell 5 or more DVDs in a day is the complement of the probability of selling less than 5 DVDs in a day, since sales <5 DVDs + sales >= 5 DVDs = 100% of the sales.
So, we know what's the probability of selling less than 5 DVDs in a day is... it's 0.1875
So, to find the possibility of selling 5 or more DVDs in a day, we take 100% of the chances (1.0) and we subtract the probability of selling <5 DVDs in a day:
P = 1.0 - 0.1875 = 0.8125
C. 0.8125 is your answer.
