It takes George 16 minutes to sew one pillowcase. If he sews 6 pillowcases, how many minutes will
he have spent sewing? Do not include any units in your answer.
Answer: The answer is 96 minutes (or 1 hr 36 minutes)
Step-by-step explanation:
Since it takes George 16 minutes to sew one pillowcase, it would take him 96 minutes/1 hr 36 minutes to sew 6 pillowcases (16x6 or 16+16+16+16+16+16/6+6+6+6+6+6+6+6+6+6+6+6+6+6+6+6)

Ashima has a Cumulative or Recurring Deposit Account in a bank for 5 years at 9% p.A. At the time of maturity, she gets 51,607.50. Find the monthly instalment.
Answer:
Monthly deposit= $684.23
Step-by-step explanation:
Giving the following information:
Number of periods= 5*12= 60 months
Interest rate= (0.09/12)= 0.0075
Future value= $51,607.5
To calculate the monthly deposit, we need to use the following formula:
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (51,607.5*0.0075) / [(1.0075^60) - 1]
A= $684.23

Step 1: Define
Identify variables
Angle θ = 33°
Opposite Leg = x
Hypotenuse = 29
Step 2: Find Angle
Substitute in variables [sine]: sin33° = x/29[Multiplication Property of Equality] Multiply 29 on both sides: 29sin33° = xRewrite: x = 29sin33°Evaluate: x = 15.794512. Given triangle ABC with sides a, b, and c
opposite angles A, B, and C, respectively,
determine which side is the longest if
MZA = 49°, mZB = 24°, and mZC = 107°.
If you need, construct this triangle on a sheet of paper.
side c
side a
side b
Impossible to determine
Answer:
Side c
Step-by-step explanation:
Generally triangles can be classified with respect to their sides, or their angles. And there is a relationship between the length of the sides and the measure of the opposite angles of a given triangle. The relationship is that; the longest length of side is the one that is always opposite to the greatest angle.
In the given question, the longest side given that m<A = 49°, m<B = 24°, and m<C = 107° of the internal angles of the triangle is side c. Since side c is opposite the greatest angle, <C.

An 8 in by 8 in square air vent is shown where AG = 8 inches. BF is the midsegment of AADG and CEis the midsegment of ADBF. Which of the
following is measure of CE2
Answer:
2
Step-by-step explanation:
if BF is the mid-segment of the triangle ADG then its measure will be half of the measure of AG so 0.5*8=4 by the (mid-segment theorem)
then CE is the mid-segment of triangle BDF, so its measure is will be half of BF, so 0.5*4=2
Answer:
CE = 2
Step-by-step explanation:
The midsegment is half the length of the third side of the triangle, then
BF = [tex]\frac{1}{2}[/tex] × DG = [tex]\frac{1}{2}[/tex] × 8 = 4 , and
CE = [tex]\frac{1}{2}[/tex] × BF = [tex]\frac{1}{2}[/tex] × 4 = 2

O x = 13.6
O x = 26
Answer:
X = 3°
Step-by-step explanation:
Since O and T are parallel you can use alternating lines
7x + 5° = 5x + 11° (alt. angles, O||T)
Move the 5x and the 5°
7x - 5x = 11° - 5°
2x = 6°
Divide both sides by 2
x = 3°
This is assuming 11 is an angle
Differentiate with respect to t
Assume x = x(t)
Assume y = y(t)
Assume z = z(t)
x^2 - y^3 + z^4 = 1
Answer:
[tex]\displaystyle 2x\frac{dx}{dt}-3y^2\frac{dy}{dt}+4z^3\frac{dz}{dt}=0[/tex]
Step-by-step explanation:
We want to differentiate the equation:
[tex]x^2-y^3+z^4=1[/tex]
With respect to t, where x, y, and z are functions of t.
So:
[tex]\displaystyle \frac{d}{dt}\left[x^2-y^3+z^4\right]=\frac{d}{dt}\left[1\right][/tex]
Implicitly differentiate on the left. On the right, the derivative of a constant is simply zero. Hence:
[tex]\displaystyle 2x\frac{dx}{dt}-3y^2\frac{dy}{dt}+4z^3\frac{dz}{dt}=0[/tex]
what is meaning of volume
Step-by-step explanation:
Volume is the measure of the capacity that an object holds. For example, if a cup can hold 100 ml of water up to the brim, its volume is said to be 100 ml. Volume can also be defined as the amount of space occupied by a 3-dimensional object or solid shape.
Answer:
the amount of space that a substance or object occupies.
basically the volume of a container, like space in a container.
Which of the following transformations
carry this regular polygon onto itself?
Each of the five lines of symmetry can be used to map the pentagon to itself in reflection.
Which transformation will carry a regular Pentagon onto itself?A polygon can change without changing its shape when it undergoes a transformation. Examples include rotation, reflection, and translation. A figure's translation is a change in position that necessitates knowledge of both the direction and the distance. The picture is the final shape that emerges from a transformation.
Five lines of symmetry make up a regular pentagon. Each of the five lines of symmetry can be used to map the pentagon to itself in reflection. Rotate the point 144 degrees in order to convert (0, -2). As a result, the 144° transformation translates the standard pentagon with the coordinates (0, -2) onto itself.
Putting a point, line, or other shape on top of a line. A regular polygon needs to be reflected over a symmetry line in order to map onto itself.
Therefore, the correct answer is option c) Reflection across L.

What is the area of the circle?
Answer:
Step-by-step explanation
radius=diameter/2
=16/2
=8 ft
area of circle=πr^2
=π*8^2
=π64 ft^2
Answer:
The area of the circle is 64π^2
Explanation:
the diameter is 16, so you divided it by 2 to get the radius, which is 8. The equation that is used to solve for area of circle is A = πr^2. So the equation that I used was A = π8^2.

Answer:
f(x) +g(x) = 4x^2 +3
f(x) -g(x) = 4x^2 -6x +1
f(x)·g(x) = 12x^3 -5x^2 +3x +2
Step-by-step explanation:
Substitute for f(x) and g(x) and simplify.
(a) f(x) +g(x) = (4x^2 -3x +2) +(3x +1)
f(x) +g(x) = 4x^2 +3

Suppose that the dollar cost of producing x ratios is c(x)=800+40x-0.2x^2. Find the average cost per radio of producing the first 40 radios.
Answer:
24radios
Step-by-step explanation:
Given that the dollar cost of producing x ratios is c(x)=800+40x-0.2x^2. Find
Average cost is expressed as dC(x)/dx
dC(x)/dx = 40-0.4x
C'(x) = 40 - 0.4x
If x = 40
C'(40) = 40 - 0.4(40)
C'(40) = 40 - 16
C'(40) = 24
Hence the average cost per radio of producing the first 40 radios is 24radios
