One limitation of pre-operational thought is the belief that non-living objects have life-like qualities?
Answer:
Animism
Step-by-step explanation:
Animism is often a major idea or thought which is developed in a child preooperational stage according to paiget's theory of cognitive development where a child's learning is driven and derived from by symbols. At this stage, a child often relates with their toys, and other inanimate objects they come across as though they were real, manipulating and transforming them to form different things including relating with these manipulated objects like they were living. This is because at this stage, a child cannot use cognitive or logic to make distinctions.

please help im desperate no. 48 and 49
Answer:
48. option C : Substitution
49. Option D : ( 3, 6)
Step-by-step explanation:
3x + y = 15 ------------- ( 1 )
y = 2x ------------------- ( 2 )
Substitute ( 2 ) in ( 1 ) :
3x + y = 15
3x + 2x = 15
5x = 15
[tex]x = \frac{15}{5} = 3[/tex]
Substitute x in ( 2 ) :
y = 2x
y = 2 × 3 = 6
The solution to the system of equation is ( 3 , 6 )
Answer:
C and (3, 6 )
Step-by-step explanation:
(48)
Since given y = 2x the best method of solving is by substitution C
(49)
Given the 2 equations
3x + y = 15 → (1)
y = 2x → (2)
Substitute y = 2x into (1)
3x + 2x = 15
5x = 15 ( divide both sides by 5 )
x = 3
Substitute x = 3 into (2) and evaluate for y
y = 2x = 2 × 3 = 6
solution is (3, 6 )
Estelle hosted a banquet for her extended family that cost $480.93. Estelle paid 9.25% sales tax and left an 18% tip on $480.93. What was the total cost?
Answer:
$563.89: total cost of the banquet
Step-by-step explanation:
Here we can to find the total cost, including tax and tip, by adding 9.25% and 18% together first. We obtain 17.25%, which translates into the decimal fraction 0.1725 and results in the amount added to the original cost, $480.93. The result is added to $480.93:
1.0000($480.93) + 0.1725($480.93) = $563.89
A shortcut would be to find the total cost, including the original $480.93 and the additional 17.25%, by multiplying $480.93 by 1.1725:
1.1725($480.93) = $563.89: total cost of the banquet

28. Barrett's mom has a flower vase that is shaped like a perfect cylinder.
The vase has a height of 9 inches, and its radius is 4 inches. What is the
total volume of water that the flower vase can hold?
Answer:
Vase volume is 452.16 in³
Step-by-step explanation:
The question asks for the volume of a cylinder of radius r and height h. The relevant formula is V = (pi)(r)^2*h
With h = 9 in and r = 4 in, that max volume (of water) is
V = (3.14)(4 in)^2*(9 in) = 452.`16 in³

if the sum of a number and half of it is 30. find the number.
Answer:
20
Step-by-step explanation:
Let us represent the number as x. In a similar sense, half the number would be [tex]\frac{x}{2}[/tex]. We know that their sum is 30, so we can write the following equation:
[tex]x+\frac{x}{2} =30\\2x+x=60\\3x=60\\\fbox{x=20}[/tex]

A regulation-size women's basketball has a diameter of 9.07 inches. What is the surface area of the basketball? Use 3.14 for π and round to the nearest tenth.
Answer:
258.3 sq inches
Step-by-step explanation:
Use the sphere surface area formula, SA = 4[tex]\pi[/tex]r²
The diameter is 9.07 inches, so the radius is 4.535 inches.
Plug in 3.14 as pi and 4.535 as r, and solve:
SA = 4[tex]\pi[/tex]r²
SA = 4(3.14)(4.535)²
SA = 258.3
So, the surface area is approximately 258.3 sq inches

E The cost for renting a car for 5 days is $200, plus the per mile fee multiplied by the number of miles driven.The cost for renting a car for 5 days is $200, plus the per mile fee multiplied by the number of miles driven.
F The cost can be calculated by multiplying the total miles driven by 0.25 and adding 200.
Answer:
A, C, E, F
Step-by-step explanation:
...............
C= 0.25x + 200 represents the rental cost of renting a car with rental fees of $200 and additional fees per 'x' mile as $ 0.25.
What is equation?" Equation is defined as the representation the relation of variables with the sign of equality."
According to the question,
'x' represents the number of miles
'C' represents the rental cost
Rental fees of a car = $200
Additional fees per 'x' miles = $0.25
As per the condition given we have,
C = 0.25x +200
The given model states that total cost of the car is equals to the rental fees of the car is $200 and the additional fees per 'x' miles is $0.25.
Hence, Option(C), Option(E) and Option(F) are the correct answer.

Answer:
D
Step-by-step explanation:
To check this answer, you could obviously graph the points, but without graphing, you can tell the line would be straight because each x value is multiplied by the same number to get the corresponding y value.
3 x 5 = 15, 4 x 5 = 20, etc. This shows linear growth. If each x value were multiplied by twice itself (3 x 6, 4 x 8, and so on), you wouldn't have a straight line because the number that x is multiplied by changes depending on the value of x.

Determine a function a(w) that models the area of the top surface of the swimming pool in terms of the width , w
Answer:
[tex]A(w) = (40 - w) * w[/tex]
Step-by-step explanation:
Given
[tex]P = 80[/tex] ---- perimeter
Required
Write the area as a function of width
The perimeter of a rectangle is:
[tex]P =2(l + w)[/tex]
Where
[tex]l \to length\\ w \to width[/tex]
So, we have:
[tex]80 = 2*(l+w)[/tex]
Divide by 2
[tex]40 = l + w[/tex]
Make l the subject
[tex]l =40 - w[/tex]
The area of a rectangle is:
[tex]A = l * w[/tex]
Substitute: [tex]l =40 - w[/tex]
[tex]A = (40 - w) * w[/tex]
Hence, the function is:
[tex]A(w) = (40 - w) * w[/tex]
