The pointer on a voltmeter is 6 in length. Find the number of degrees through which the pointer rotates when it moves 2.1 centimeters on the scale.
Anyone know?
Answer:
The number of degrees through which the pointer rotates is approximately 20°.
Step-by-step explanation:
If the pointer moves, then it is moving in form of an arc. Since the length of the pointer is 6cm, then radius formed with the pointer is 6cm in length.
When it moves 2.1cm on the scale, an arc with length of 2.1cm is formed.
Using the formula for the length of an arc, we can get the desired number of degrees, angle in degrees, needed.
Length of an arc = 2πrA/360°
Length of the arc = 2.1cm
r = 6cm
A = the angle in degrees.
Therefore we have:
2.1 = 2xπx6xA/360
2.1 = πA/30
(2.1x30)/π = A
A ≈ 20°
The number of degrees through which the pointer rotates when it moves 2.1 centimeters on the scale is; 20°
When the pointer moves 2.1 centimetres on the voltmeter scale;
This means that the length of the arc formed is; 2.1 cm.In essence, since the length of an arc is given by;
L(arc) = (p/360) × 2 × π × Rwhere, R = radius = 6cm
p = angle subtended = ?π = 3.142.Therefore;
2.1 = (p/360) × 2 × 3.142 × 6p = (360×2.1)/(2×3.142×6)p = 20°.

Answer:
Total weight is 150 kg
Step-by-step explanation:
Firstly, we need the weight of the diagonal
To get this, we shall use the Pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the squares of the two other sides
The diagonals stand for the hypotenuse
Thus, we have that;
d^2 = 5^2 + 12^2
d^2 = 25 + 144
d^2 = 169
d^2 = 13^2
d = 13
The 6 sides technically includes the whole rectangle sides, then the two diagonals
The total length here is;
2(5 + 12 + 13) = 60 meters
Steel weight is 2.5 kg per meter
Weight of 60 m will be ;
60 * 2.5 = 150 kg

Step-by-step explanation:
Prime numbers are those numbers in which they can be divided by itself and 1. They are formed by two natural numbers higher than 1 but not by multiplying natural numbers that are smaller.
So; using index notation to writing 512 as a product of primes; we have:

Dennis can walk about 2 5/6 miles each hour. About how far can he walk in 3 hours 15 minutes?
Answer:
24 13/34
Step-by-step explanation:
The distance covered by Dennis will be 9.23 miles.
What is speed?Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is a scalar quantity and does not require any direction to represent it.
Given that Dennis can walk about 2(5/6) miles each hour. The distance covered by Dennis in 3 hours 15 minutes will be calculated as:-
Distance = 2 ( 5 / 6) x 3 hour 15 minute
Distance = 2.84 x 3 ( 1 / 4)
Distance = 2.84 x 3.25
Distance = 9.23 miles.
Therefore, the distance covered by Dennis will be 9.23 miles.

An ice cream shop is choosing a milk delivery service. The Spotted Cow charges $2.80 per gallon, plus a $2 delivery fee. Dairy Farms charges $2.10 per gallon, plus a $10 delivery fee. If the ice cream shop uses 20 gallons a milk per week, which service is a better deal? Group of answer choices
Answer:
The Dairy Farm is better deal.
Step-by-step explanation:
Given that:
Per gallon charges of the Spotted Cow = $2.80
Delivery fee = $2
Let,
x be the gallons of milk.
S(x) = 2.80x + 2
Putting x = 20
S(20) = 2.80(20) + 2 = 56 + 2
S(20) = $58
Per gallon charges of the Dairy Farms = $2.10
Delivery fee = $10
D(x) = 2.10x + 10
Putting x = 20
D(20) = 2.10(20) + 10 = 42 + 10
D(20) = $52
Hence,
The Dairy Farm is better deal.

Use the drop-down menus to complete each equation so the statement about its solution is true.
Answer:
See below
Step-by-step explanation:
Equation given
2x + 9 + 3x + x = 6x + 9No solution ⇒ 6x + a, a≠9
Parallel lines, same slope and different y-interceptOne solution ⇒ ax + b, a≠6
Lines with different slopeInfinitely many solutions ⇒ a(6x + 9), a≠ 0
Overlapping lineswhat is the percent rate of change in function y = (0.98) ^ x? determine whether the function represents exponential growth or exponential decay
C. 2%; exponential decay
You can use the fact that increasing power of values lying between 0 and 1 results in less and less values.
The percent rate of change in given function is -2%
The function represents exponential decay.
Given that:The function: [tex] y = (0.98) ^ x[/tex]To find:Percent rate of change in given function.Is it representing exponential growth or exponential decay?Finding percent rate of change in given function:
For finding this, first find how much the output y changes if we change x from x to x + 1.
Output when x = x: [tex]y = (0.98)^x[/tex]
Output when x = x+1: [tex]y = (0.98)^{x+1}[/tex]
Difference in output if x goes from x to x+1: [tex](0.98)^{x+1} - (0.98)^x = (0.98)^x(0.98 - 1) = -0.02 \times (0.98)^x[/tex] (this change occurs if we increase input x by 1 unit, thus this also represents the rate)
Rate of change of function per unit increment = [tex]-0.02 \times (0.98)^x[/tex]
The percentage of rate of change is found as:
[tex]\text{Percent rate of change\:} = \dfrac{\text{Rate of change} \times 100}{\text{previous value}} = \dfrac{-0.02 \times (0.98)^x \times 100}{(0.98)^x} \\\\ \text{Percent rate of change\:} = -2\%[/tex]
Thus, the percent rate of change is -2%
The negative sign shows that the value is decreasing, thus showing that function shows exponential decay.
