Answer:
true
Step-by-step explanation:
if an object is losing heat energy, it turns cold, and can turn into a solid, for example, water turning into ice. If you apply heat on ice, it's turns back to water. IF you apply heat to water, it vaporizes, and turns into gas.

The junior class sold 120 turkey dinner plates and 200 chicken dinner plates for a total of $2,150. The senior class sold 100 turkey plates and 300 chicken plates, raising $2,625. What was the cost of each turkey dinner plate? What is the cost of each chicken plate?
Answer:
Write the system of equations with 2 unknowns x and y denoting the prices of two types of chickens:
(1) 120x + 200y = 2150
(2) 100x + 300y = 2625
Solving the system of equations above we have 2 solutions:
x = 15/2 = $ 7.5 and y = 25/4 = $ 6.25

solve for x
7(8-x) = 210
Answer:
x=266
Step-by-step explanation:
I'm sure if this is correct but this is how I did it seven times eight is 56 and you have to subtract that number by x so x would have to be bigger so it would be 56 minus 266
will give you 210
Answer:
x=-22
Step-by-step explanation:
7(8-x)=210
you would use the distributive property
56-7x=210
then subtract both sides by 56
-7x=154
then divide both sides by -7
x=-22

C) y= 1/2x +2; -4 ≤ x ≤ 6
D ) y=-2x+2; -∞
Answer:
1. C
2. C
Step-by-step explanation:
1. x = [tex]\sqrt{t}\\[/tex], y = 4t +3
Solve for t:
t = [tex]x^{2}[/tex]
Plug in t:
y = 4([tex]x^{2}[/tex] ) +3
y = 4[tex]x^{2}[/tex] +3
2. x = 2t, y = t + 2
Solve for t:
t = x/2
Plug in t:
y = 1/2x + 2
The sketch of this crayon represents an irregular polygon. Find the area of the figure. 21.75 cm²
75 cm²
37.5 cm²
40.5 cm²
The total area of the sketch will be 40.5 cm².
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
Given, The sketch of this crayon represents an irregular polygon.
Dimension of the polygon are given in the figure,
To calculate the area of the given figure first we need to break this into two parts:
The first one will be rectangular form with a length of 12.5 cm and a width of 3 cm
The second one will be in triangular form with a height of 2 cm and a base of 3 cm.
Area of rectangle = length * width
in our case,
Area of rectangle = 12.5*3
Area of rectangle = 37.5 square cm
Area of triangle = 1/2 base *height
In our case,
Area of triangle = 1/2* 3 * 2
Area of triangle = 3 square cm
So,
The total area of the sketch = area of rectangle +area of the triangle
The total area of the sketch = 37.5 + 3
The total area of the sketch = 40.5 Square cm
Therefore, the total area of the sketch will be 40.5 cm².

Answer:
x= 9, x= 2
Step-by-step explanation:
x^2- 2x- 9x+ 18= 0
x (x-2) -9 (x-2)
(x-9) (x-2)
x-9= 0, x-2= 0
Therefore, x= 9, x= 2

hope this helps you i am taking the test now LOL
plz mark me brainlist i think its called
Answer:
Its 16
Step-by-step explanation:
Because 180 - 109 is 71, and 71 plus 90 is 164, and 180 - 164 is 16 therefore that is your missing angle.
Find the angle of this sector.
6 cm
NEED ASAP
5 cm
Answer:
x ≈ 68.8°
Step-by-step explanation:
The length of the arc of a sector is calculated as
arc = circumference × fraction of circle , that is
6 = 2πr × [tex]\frac{x}{360}[/tex] = 2π × 5 × [tex]\frac{x}{360}[/tex] = 10π × [tex]\frac{x}{360}[/tex] ( multiply both sides by 360 )
2160 = 10πx ( divide both sides by 10π )
68.7549... = x , that is
x ≈ 68.8° ( to 1 dec. place )

Helllllp
9514 1404 393
Answer:
74
Step-by-step explanation:
The recursive definition is for an arithmetic sequence with a first term of -6 and a common difference of 4.
The general term of such a sequence is ...
a(n) = a(1) +d(n -1)
This sequence is ...
a(n) = -6 +4(n -1) = 4n -10
Then for n = 21, the term is ...
a(21) = 4(21) -10 = 84 -10
a(21) = 74
