A circular plate has circumference 32 inches. What is the area of this plate? Use 3.14 for pi. The area of this plate is about nothing square inches.
Answer: The area of the plate is 81.67 in^2
Step-by-step explanation:
If we have a circle of radius R, the area of this circle can be computed as:
A = pi*R^2
where pi = 3.14
And the circumference is:
C = 2*pi*R
and we know that this is equal to 32 in, then:
32in = 2*pi*R
Now we can isolate R, and we get:
32in/(2*pi) = R
32in/(2*3.14) = R = 5.1 in
Then the area of the plate is:
A = 3.14*(5.1in)^2 = 81.67 in^2
Determine how far the vehicle travels in 3 hours.
A helicopter travels 240 miles every 2 hours.
Answer:
360 miles
Step-by-step explanation:
The unit rate here is (240 miles) / (2 hours), or 120 mph.
In 3 hours the vehicle travels (120 mph)(3 hrs) = 360 miles
Answer:
360
Step-by-step explanation:
240/2 =120 So, you want to add 120 to 240 to get 360.

The price of a holiday was decreased by 12 percent to 600 . What was the price before the decrease?
Price before decrease = x
If price before decrease is 100, then price after decrease = 100- 12 = 88
100:88 = x:600
100/88=x/600
100/88 ×600 = x
681.82 =x
Price before decrease =681.82

Answer:
x = 26°
Step-by-step explanation:
for these triangles to be congruent m∡B must equal m∡E
m∡B = 180 - (114+23) = 43°
to find 'x': x + 17 = 43
x = 43 - 17 = 26

Actually Welcome to the Concept of the linear equation in two variables.
So we have to form two equations to solve this.
Let the number of children be 'x' and number of adults be 'y'.
hence, we get as,
x+y = 630 ..... (1)
and also, to their total cost spending, we get as,
1.5x + 2.25y = 1170 ...... (2)
solving (1) and (2) we get as,
Number of children were = 330
and Number of Adults were = 300

Determine the number of terms n :
a 1 = 15, a n = 79, S n = 423
Answer:
The number of terms in the sequence is 9
Step-by-step explanation:
We want to get the number of terms
Mathematically, we have the formula for the sum of terms in an arithmetic sequence as
[tex]sn = \frac{n}{2} (a + 1)[/tex]
a represents the first terms, and i represent the last term
[tex]423 = \frac{n}{2} (15 + 79) \\ \\ 423 \times 2 = 94(n) \\ \\ 94n = 846 \\ \\ n = \frac{846}{94} \\ \\ n = 9[/tex]

Does any one know how to to do Determining the GFC
solved in fully simplified slope intercept form
Answer:
-1/2
Step-by-step explanation:
Answer:
y = -1/2x + 1
Step-by-step explanation:
(0,1) and (2,0)
Slope:
m=(y2-y1)/(x2-x1)
m=(0-1)/(2-0)
m=(-1)/2
m= -1/2
Slope-intercept:
y - y1 = m(x - x1)
y - 1 = -1/2(x - 0)
y - 1 = -1/2x
y = -1/2x + 1

Solving systems of equations by graphing. how do you do this
Answer:
Solve systems of equations by graphing
A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
Example
[tex]\left \{ {{y=2x+2} \atop {y=x-1}} \right.[/tex]
Graph the equations in a coordinate plane
The two lines intersect in (-3, -4) which is the solution to this system of equations.

A rectangular fish tank is shown above. The base of the tank has an area of 58.4 feet2. What is the volume of water in the tank?
Answer:
525.6 ft^3 based on a Height of 9 ft
Step-by-step explanation:
Given data
Area of Base= 58.4 ft^2
The expression for the volume of a rectangular tank is given as
Volume= L*W*H
Volume= Area*Height
Although the question was not specific about the height, it is important that we have the height to get the volume
Say the height is 9 ft
Hence the volume is
V= 6*58.4*9
V= 525.6 ft^3

What is the measure of each angle in a pentagon if the lengths of all five sides are equal?
A. 180
B. 120
C. 108
D. 60
Answer:
C (108)
Step-by-step explanation:
Angles in a pentagon must add up to 540 degrees.
All sides equal mean all angles are equal
so all you must do is divide 540 by 5, which gets you to 108.
You can use inverse operations to check the work
108 x 5 = 540

Step-by-step explanation:
(5m^2)^3 is just an expanded way of saying 125m^6. 125m^6/5m^9 is going to get you 25/m^3, as the 6 and the 9 cancel to get you 3 on the denominator, and 125/5 gets you 25.

calculate b and a
Answer:
b=61
a=14
Step-by-step explanation:
The two lines are parallel, so
b= a+47
180- (47*2)=180-94= 86
33+86=119
b=180-119=61
a=b-47
a=61-47=14

Answer:
-64a^13 :)
I hope this helped you a bit!
Step-by-step explanation:
Apply the product rule to 4a^3.
-4^3 (a^3)
Raise -4 to the power of 3.
-64 (a^3)^3*a^4
Multiply the exponents in (a^3)^3.
Apply the power rule and multiply exponents
-64a^3*3*a^4
Multiply 3 by 3.
-64a^9*a^4
Multiply
a^9
by a^4
by adding the exponents.
Move a^4
-64 (a^4 a^9)
Use the power rule to combine exponents
-64a^4+9
Add 4 and 9.
-64a^13
