The face of a clock has a circumference of 14π inches. What is its area?
Answer:
A = 49π
Step-by-step explanation:
C = πd
if d = 14 then r = 7
A = πr²
A = π · 7²
A = 49π
In the rhombus,

a. x = 12, y = 84, z = 20
b. x = 6, y = 174, z = 20
c. X= 6, y = 84, z = 10
d. x = 12, y = 174, z = 10
For the M1 angle, we can conclude the size of angle is 90°. Do the angle equation like this :
15x=90
x = 90/15
x = 6
Do the same thing in M2 :
Subtitute the x value to equation, then evaluate the value by using 90 because it's the same.
x+y=90
6+y=90
y=90-6
y=84
M3 value is same, 90°
9z=90
9z/9 = 90/9
z=10

What is the rate of change of the proportion y=9x
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The rate of change of the proportion y = 9x is 9.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
y = 4x +2 is an equation.
x + 2x + 3 = 4 is an equation.
We have,
y = 9x
The rate of change of this equation can be calculated by finding its differentiation.
Now,
y = 9x
Differentiating with respect to x we get,
dy/dx = 9dx/dx
dy/dx = 9
Thus,
The rate of change of the proportion y = 9x is 9.

Salesman Scott received $2,792.79 for selling a property. If the gross commission was 6.5 % of the sale price, the listing salesman received 12% of the gross commission and Scott received 45% of the balance, how much did the property sell for?
Answer: The property sold for $5,870.41.
Step-by-step explanation:
Let x be the selling price of the property.
Then, gross commission = 6.5% of x = 0.065x
listing salesman received = 12% of ( 0.065x) = 0.12 (0.065x) = 0.0078 x
Balance = x - ( 0.065x) - (0.0078 x)
= (1+0.065-0.0078)x
= 1.0572x
Scott received = 45% of (1.0572x)
=0.45 (1.0572x)
= 0.47574x
Now, [tex]0.47574x=2,792.79[/tex]
[tex]\Rightarrow\ x=\dfrac{2792.79}{0.47574}\\\\\Rightarrow\ x=5870.41[/tex]
Hence, the property sold for $5,870.41.

Translate X(2,3) Y(0,0) Z(4,4) 2 units right and 3 units up
Answer:
X(4, 6) Y(2, 3) Z(6, 7)
Step-by-step explanation:
If you want to translate something right on a number line, then you are essentially adding to it. Thus you would just add 2 to each of the x values of the coordinates. The same applies with translating something up, all that really means is that you are adding to each of the y values so all you have to do is add 3 to each of the y values and you get your answer.
Answer:
X:(4,6), Y:(2,3), Z:(6,7)
Step-by-step explanation:
2 units right implies a change on the x-axis, meaning you add 2 units to the x of the coordinate pair (x, y). 3 units up implies a change in Y, you apply the same rule and add 3 to the Y of the pair.
2 units right (add 2 to x pair coordinate)
X: (2,3) --> (4,3)
Y: (0,0) --> (2,0)
Z:(4,4) --> (6,4)
and 3 units up (add 3 to y pair coordinate)
X: (4,3) --> (4,6)
Y: (2,0) --> (2,3)
Z: (6,4) --> (6,7)

A weight of 6 lb stretches a spring a distance of 12 in. Find the constant k for the spring.
Answer:
Let F = the force (6 lbs) and x be the distance that the spring is stretched (12 inches).
F = kx
6 lb = k*(12 in.)
6/12 = k = 0.5 lb/in.
A weight of 6 lb stretches a spring a distance of 12 in. The constant k for the spring will be 0.5 lb/in.
How to obtain acceleration from force applied on an object?If the object is of mass m kg and force applied on it is of F N in the direction of motion, then the acceleration of that object is evaluated as:
a= F/m
Given; A weight of 6 lb stretches a spring a distance of 12 in.
Also,
Let F = the force and x be the distance that the spring is stretched
F = kx
6 lb = k*(12 in.)
6/12 = k = 0.5 lb/in.
Therefore, the constant k for the spring will be 0.5 lb/in.

Which costs more per issue, 18-issue subscription for $40.50 or a 12-issue subscription for $33.60?
Answer:
12-issue subscription
Step-by-step explanation:
18-issue sub = $40.50 ÷ 18 = $2.25/issue
12-issue sub = $33.60 ÷ 12 = $2.8/tissue
=> The 12-issue subscription costs more per issue (2.8 > 2.25)
Answer:
so you would divide the cost by the issue
the 18 issue is $2.25 per issue
the 12 issue is $2.80 per issue
the 12 issue costs more

True or False
A linear function has a graph as a straight line so the given statement is False.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
A linear function is given by
y = mx + c where m is the slope and constant.
Since it is constant it means it should be a straight line in coordinate geometry.
Therefore a linear function always makes a straight line, not a parabola.
Hence "A linear function has a graph as a straight line so the given statement is False".
