how do i make a area model of 4.6 and 3
Answer:
Area model is one of a simple step to understand the given situation. So to make it simple, we need to decompose the number.
given number = 4.6 and 3
First we need to get the whole number and start multiplying:
Whole number of 4.6 => 4
whole number of 3 => 3
Now, let’s start multiplying the whole number
=> 4 x 3
=> 12
Then let’s multiply the remaining decimal:
=>.6 x 3
=> 1.8
Then add
=> 12 + 1.8
= 13.8
we know that
The area model for multiplication is a pictorial way of representing
multiplication. In the area model, the length and width of a rectangle
represent factors, and the area of the rectangle represents their product
So
in this problem
the factors are
l e n g t h 4.6 w i d e 3
decompose the number
4.6
4.6 = ( 4 + 0.6 ) A r e a o f r e c t an g l e = A r e a r e ct a n g l e 1 + A r e a re c t a n g l e 2 = ( 4 + 0.6 ) ∗ 3 = 4∗ 3 + 0.6 ∗ 3 = 12 + 1.8 = 13.8
see the attached figure to better understand the problem
therefore
the answer is
the product of
4.6
and
3
is equal to
13.8

1. Write in interval notation: 2|3-4x|+5>4
2. Write in set builder notation: |2-3x|=|x-3|
Answer:
See bolded below
Step-by-step explanation:
1. First solve the inequality:
2|3-4x|+5>4 [subtract 5 from both sides]
2|3-4x| > - 1 [divide both sides by 2]
|3-4x| > - 1/2
Since all absolute values are always greater than or equal to 0, the solution would be: All Solutions. Respectively in interval notation we have (- ∞, ∞)
2. Start by solving the equation:
|2-3x|=|x-3|,
2-3x = x-3, 2-3x = -(x - 3)
x = 1.25, x = -0.5
In set builder notation: { x | x ∈ {1.25, -0.5} }

An item is regularly priced at $60 . Lucy bought it on sale for 60% off the regular price. How much did Lucy pay?
Answer:
$24
60% of 60 is 36 so to subtract 60% from the total $60 you would do 60-36=24
Oceanside bike rental shop charges seventeen dollars plus seven dollars an hour for renting a bike. Jason paid eighty dollars to rent a bike. How many hours did he have to pay to have the bike checked out?
Answer:This is a linear equation.
y = mx+b
y is the total cost.
The slope m is the rate: that's 9 dollars per hour.
x is the number of hours.
b is the initial value: that's 16 dollars.
y = 9x+16
The problem states that the cost was 79 dollars.
Substitute that for y and solve for x.
79 = 9x+16
63 = 9x
x = 7 hour
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
80-17=63
63/7 = 9
7 times 9 = 63

Step-by-step explanation:
Function f approximately represents the trajectory of an airplane in an air show, where x is the horizontal distance of the flight, in kilometers. What is the symmetry of the function?
Answer:
[tex](\frac{3}{2},102)[/tex]
Step-by-step explanation:
Given
[tex]f(x)=88x^2-264x+300[/tex] --- Missing from the question
Required
The symmetry
First, we express f(x) as: [tex]f(x) = a(x - h)^2 + k[/tex]
Where the symmetry is: (h, y) and x = h
Equate f(x) to 0
[tex]88x^2-264x+300 = 0[/tex]
Subtract 300 from both sides
[tex]88x^2-264x+300 - 300= 0 - 300[/tex]
[tex]88x^2 - 264x= - 300[/tex]
Factorize
[tex]88(x^2 - 3x) = -300[/tex]
On the left-hand side, the coefficient of x is -3.
Divide by 2 and add the square to both sides.
So, we have:
[tex]88(x^2 - 3x) + (\frac{3}{2})^2 = -300 + (\frac{3}{2})^2[/tex]
Multiply the new terms by 88 (to make it factorizable)
[tex]88(x^2 - 3x ) +88* (\frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]
Factorize
[tex]88(x^2 - 3x + (\frac{3}{2})^2) = -300 + 88 * (\frac{3}{2})^2[/tex]
The quadratic expression in the bracket is a perfect square. This gives:
[tex]88(x - \frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]
[tex]88(x - \frac{3}{2})^2 = -300 + 88 * \frac{9}{4}[/tex]
[tex]88(x - \frac{3}{2})^2 = -300 + 22 * 9[/tex]
[tex]88(x - \frac{3}{2})^2 = -102[/tex]
Add 102 to both sides
[tex]88(x - \frac{3}{2})^2 +102= -102 + 102[/tex]
[tex]88(x - \frac{3}{2})^2 +102= 0[/tex]
Equate to y
[tex]y = 88(x - \frac{3}{2})^2 +102[/tex]
Recall that:
The symmetry is: (h, y)
By comparison with [tex]f(x) = a(x - h)^2 + k[/tex] and x = h
[tex]h = \frac{3}{2}[/tex]
So: [tex]x = \frac{3}{2}[/tex]
Substitute [tex]x = \frac{3}{2}[/tex] in [tex]y = 88(x - \frac{3}{2})^2 +102[/tex]
[tex]y = 88(\frac{3}{2} - \frac{3}{2})^2 +102[/tex]
[tex]y = 88(0)^2 +102[/tex]
[tex]y = 0 +102[/tex]
[tex]y = 102[/tex]
So, the symmetry is: [tex](\frac{3}{2},102)[/tex]

What is the measure of angle LMN ?
Answer:
g = 9°
hence LMN = 135 + 18 = 153°
Step-by-step explanation:
straight line is 180°
180 - 18 = 162
162 = 18g
g = 9
Answer:
Step-by-step explanation:
So try to find the total angle so
15g+18+3g=180
18g=180-18
18g=162
g=9
angle LMN=15x9+18
=135+18
LMN=153 degrees
angle PMN=3x9
= 27 degrees
the volume of a soap bubble is 2,308.4 mm ^3. Find the radius and diameter of the soap bubble. Use 3.14 for pi
Answer:
r = 8.2mm
d = 816.4mm
Step-by-step explanation:
Let the soap be spherical in nature
Volume of a sphere = 4/3 πr³
r is the radius
Given that V = 2308.4mm^3
Substitute
2308.4 = 4/3 πr³
2308 = 4/3 (3.14)r³
2308.4 * 3 = 12.56r³
6,925.2 = 12.56r³
r³ = 6,925.2 /12.56
r³ = 551.37
r = 8.2mm
diameter = 2r
diameter = 2(8.2)
diameter = 16.4mm

Can someone please help me with math
Answer:
B
Step-by-step explanation:
they want us to find the equation in slope intercept form
which is y= mx + b
where m = slope and b = y intercept
the slope is change in y over change in x
as y goes up 1 x goes up 1 so the slope is 1 or m=1
the y intercept is at point (0,1)
so the y intercept is 1
now we add it all together and get that the equation Is
y=x+1
