Answer:
The rate of change of each circular surface of the dough is approximately 150.796 in.²/minute
Step-by-step explanation:
The given parameters are;
When the radius of the dough, r = 12 inches, the radius is increasing at 2 inches per minute
Therefore, we have;
dr/dt = 2 in./min
The area of the circular surface of the dough, A = π·r²
The rate of change of each (top or bottom) circular surface area of the dough dA/dt is given as follows;
dA/dt = d(π·r²)/dt = π·2·r·dr/dt
Where;
r = 12 in.
dr/dt = 2 in./min
Substituting, we have;
dA/dt = π·2·r·dr/dt = π × 2 × 12 in. × 2 in./min ≈ 150.796 in.²/minute.
The rate of change of each circular surface of the dough = dA/dt ≈ 150.796 in.²/minute.
I do draws a blueprint of a house using the scale 1 in equals 6 ft in the kitchen has a length of 24 ft what is the length of the kitchen on the blueprint
Answer:
Length of kitchen on blueprint = 4 in.
Step-by-step explanation:
Scale used to draw a blueprint of a house :
6 feet = 1 in.
Therefore, 1 feet = [tex]\frac{1}{6}[/tex] in.
If the length of kitchen = 24 feet
Then the length of kitchen on the blueprint will be
= [tex]\frac{1}{6}\times 24[/tex]
= 4 in.
Therefore, length of kitchen on blueprint is 4 in.

Answer:
a = 4
Step-by-step explanation:
[tex] \sin(theta) = \frac{opposite}{hypotenuse} [/tex]
[tex] \cos(theta) = \frac{adjacent}{hypotenuse} [/tex]
[tex] \tan(theta) = \frac{opposite}{adjacent} [/tex]
hypotenuse = a
opposite = 2√3
adjacent = b
theta = 60°
the best formula to use is the first formula cause we have all the values to substitute in it in order to find the value of a
[tex] \sin(60) = \frac{2 \sqrt{3} }{a} [/tex]
[tex] \frac{2 \sqrt{3} }{ \sin(60) } = a[/tex]
[tex]4 = a[/tex]
[tex]a = 4[/tex]

Step-by-step explanation:
In each empty table square, fill in the value that is computed by replacing 'n' in the rule to the left with the value of 'n' above that square.
For example:
The upper left empty square will be filled with ...
n -5 . . . . with n replaced by 1
1 - 5 = -4 . . . . the value that goes in the upper left square.
__
Another example:
The lower right square will be filled with ...
4n -3 . . . . with n replaced by 100
4·100 -3 = 400 -3 = 397 . . . . the value that goes in the lower right square
_____
Additional comment
When there are numerous table values to fill, it can be convenient to let a spreadsheet do the calculations. Here, each formula was entered once, then filled to the right.

Use the diagram to prove that ∆CAS≅TAS.
The two-column proof that shows that ΔCAS ≅ ΔTAS by HL Congruence Theorem is shown in the table attached below.
What is the HL Congruence Theorem?The HL Congruence Theorem is used to prove two right triangles congruent if both triangles have a pair of congruent hypotenuse and a pair of congruent legs.Thus, ΔCAS and ΔTAS both have a pair of congruent legs and a pair of congruent hypotenuse. Therefore, the two-column proof that shows that ΔCAS ≅ ΔTAS by HL Congruence Theorem is shown in the table attached below.

-81 = 5x + 3x + 3x - 1
solve the multi step equation
Answer:
x= -7.27
Step-by-step explanation:
-81 = 5x + 3x + 3x - 1
combine all like terms
-81=11x-1
add 1 on both sides
-81=11x-1
+1 +1
-80=11x
divide by 11 on both sides to get x by itself
-80/11=11x/11
x=-7.27

Answer:
The time he spent at his friend's house is represented by the horizontal line, from .5 to 1.5 hours, which means he stayed at his friend's house for 1 hour.
Answer:
1 hour
Step-by-step explanation:
1) so lets look at the various aspects of this graph,
the first thing we see is a downhill spike from(0,4) to (0.5,2)
we can assume this segment is from riding to his friends house from school, as thats the first thing stated in this scenario. Next we notice a horizontal line(note: horizontal line means 0 slope, AKA no distance travelled) since Joey is not travelling at this time(hence the horizontal line) we can assume that thats when he was at his friends house. to find the amount of time he was at his friends house simply subtract the endpoints of the horizontal line
so: 1.5-0.5=1
he was at his friends house for 1 hour

The area of a rectangle is 276.9 m². If the length is 15 m, what is the perimeter of the
rectangle?
Answer:
[tex]66.92\:\mathrm{m}[/tex]
Step-by-step explanation:
The area of a rectangle is given by [tex]l\cdot w[/tex] where [tex]l[/tex] is the length of the rectangle and [tex]w[/tex] is the width of the rectangle. Therefore, based on the information given, we can write the following equation to solve for the width:
[tex]15\cdot w=276.9,\\w=\frac{276.9}{15},\\w=18.46\:\mathrm{m}[/tex].
The perimeter of a rectangle is given by [tex]p=2w+2l[/tex]. Therefore, the perimeter of the rectangle is:
[tex]2(15)+2(18.46)=\fbox{$66.92\:\mathrm{m}$}[/tex].
