David earned a raise of an additional $2.00 per hour. Initially, he started at $14.00 an hour. What is the percent increase in David’s hourly pay? Round percentage to the tenths place.
2.1%
Step-by-step explanation:
I don't really know how to explain what I did on paper But I got it right on the assignment : D
The percent increase in David’s hourly is;
14.3%
Percent increaseDavid's initial pay per hour = $14 per hourIncrease per hour = $2Thus;
New amount paid per hour = $14 + $2 = $16
Thus;
Percent increase in David's hourly pay = (2/14) × 100% = 14.3%

Halla la ecuación de la circunferencia con r=10 y cuyo centro es el punto medio que une los puntos del segmanto A=(-7,-6) B(3,14). Escribe la ecuación en la forma ordinaria.
Responder:
(x + 2) ² + (y-4) ² = 100
Explicación paso a paso:
La ecuación de un círculo se expresa como (x-x0) ² + (y-y0) ² = r²
r es el radio
(x0, y0) es el centro
Dado que el centro representa el punto medio de (-7, -6) y (3,14)
x0 = -7 + 3/2
x0 = -4/2
x0 = -2
y0 = -6 + 14/2
y0 = 8/2
y0 = 4
Sustituir en la expresión
(x - (- 2)) ² + (y-4) ² = 10²
(x + 2) ² + (y-4) ² = 100
Por lo tanto, la ecuación requerida del círculo es (x + 2) ² + (y-4) ² = 100
y= -3x + 1 and y= x - 3
Answer:
x= 1
y= -2
Step-by-step explanation:
equation (1): y= -3x+1
equation (2): y=x-3
solve the system of equations by substitution:
step1: sub ( x-3 ) for y in equation 1:
y = -3x+1
x-3 = -3x+1
step2: simplify the equation to get x:
(add 3 for both sides)
x = -3x+4
(add 3x for both sides)
4x = 4
(divide 4 from both sides)
x = 1
step3: sub the value of x (x=1) in equation 2:
y = x-3
y = 1-3
step4: solve the equation to get y:
y = -2

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
By the figure, the coordinate of triangles are,
D = (- 5, 1)
E = (- 2, 3)
F = (- 3, - 2)
Hence, By using distance formula;
DE = √ (- 5 + 2)² + (1 - 3)²
= √9 + 4
= √13
EF = √ (- 2 + 3)² + (3 + 2)²
= √1 + 25
= √26
FD = √ (- 5 + 3)² + (1 + 2)²
= √4 + 9
= √13
Thus, We have;
⇒ DF ≅ FD

PLS HELP WILL GIVE BRAINLIEST!! Identify this set of lines as parallel, perpendicular, or neither.
Answer:
neither
Step-by-step explanation:
Answer:
neither
Step-by-step explanation:
parallel lines have the same slope
perpendicular lines have the opposite of the reciprocal of the slope of the other line
The slope of the first line is 3 and the slope of the second line is -3.
If the lines were parallel, the slopes would be the same, so 3 = -3 which is not true, so they aren't parallel.
If the lines were perpendicular, the slope of the second line would be the opposite reciprocal of 3, or -1/3. -1/3 does not equal 3, so these lines are not perpendicular

Noah and Lin are marketing paper cones to hold popcorn to hand out at parent math night. They want the cones to hold 9 cubic inches of popcorn. What are two different possible values for height h and radius r for the cones?
if h=3, then r=
if r=2, then h=
Answer: r = 1.69 inches
h = 2.15 inches
Step-by-step explanation: Volume of a solid is the amount of space contained within a solid.
Volume of a cone is directly proportional to radius and height:
[tex]V=\frac{1}{3}\pi r^{2}h[/tex]
They want the cones to hold the same volume of 9 cubic inches.
If height is 3:
[tex]9=\frac{1}{3}\pi r^{2}3[/tex]
[tex]\pi r^{2}=9[/tex]
[tex]r^{2}=2.864[/tex]
r = 1.69 inches
When height is 3, radius is 1.69 inches for a cone to have 9 cubic inches of volume.
If radius is 2:
[tex]9=\frac{1}{3}\pi (2)^{2}h[/tex]
[tex]h=\frac{9(3)}{4 \pi}[/tex]
h = 2.15 inches
If radius is 2 inches, height of the cone is 2.15 inches.

Ashleigh wants to double her money. She put $5,000 in a bank account that pays 4% compounded continuously. How long will it take her to double her money? (Round to
Answer:
approximately 17.3 years
Step-by-step explanation:
Compound interest is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + r/n)^{nt}[/tex]
The formula used to find continuously compounded is:
t = log (A/P) / r
The time it will take to double her money is 17.329 years.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + r/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
P = $5,000
r = 4%
Amount = 2 x 5000 = $10,000
n = infinite number of times.
Now,
Solve the equation for t
The formula used to find for continuously compounded is:
t = log (A/P) / r
t = log (10,000.00/5,000.00) / 0.04
t = 17.329 years
Thus,
The time it will take to double her money is 17.329 years.

Josh and Raheem both invest some money.
Josh invests £1200 at Banks’R’us, who pay 4% simple interest per year.
Raheem invests £1250 at Bank World who pay 3% compound interest per year.
They invest the money for 5 years.
Who has the most money in their account after 5 years?
;v;
Answer:
Raheem
Step-by-step explanation:
Josh :
using simple interest formula :
Final amount = P(1 + rt)
Final amount = 1200(1 + 0.04*5)
Final amount = 1200(1.2)
Final amount = £1440
Raheem :
Using compound interest formula :
Final amount = P(1 + r/n)^nt
Final amount = 1250(1 + 0.03)^5
Final amount = 1250(1.03)^5
Final amount = £1449.09
Raheem has more money

help pls
The solution is 32 1/3 , 33 1/3 and 34 1/3
The three consecutive numbers which have a sum of 100 is given by the equation A = 32 1/3 + 33 1/3 + 34 1/3
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first number be = n
Let the second number be = n + 1
Let the third number be = n + 2
So , the sum of all the three consecutive numbers is 100
Substituting the values in the equation , we get
n + ( n + 1 ) + ( n + 2 ) = 100 be equation (1)
On simplifying the equation , we get
3n + 3 = 100
Subtracting 3 on both sides of the equation , we get
3n = 97
Divide by 3 on both sides of the equation , we get
n = 32 1/3
So , the first number n = 32 1/3
Second number = n + 1 = 33 1/3
Third number = n + 2 = 34 1/3
Therefore , A = 32 1/3 + 33 1/3 + 34 1/3 = 100
Hence , The three consecutive numbers which have a sum of 100 is given by the equation A = 32 1/3 + 33 1/3 + 34 1/3

Three numbers A, B and C are in the ratio 7: 2: 4. The sum of the three numbers is 104. What is the number C?
Answer:
C = 32
Step-by-step explanation:
The numbers are in the ratio 7 : 2 : 4 = 7x : 2x : 4x ( x is a multiplier ) , then
7x + 2x + 4x = 104
13x = 104 ( divide both sides by 13 )
x = 8
Thus C = 4x = 4 × 8 = 32
