Marcie Bruno received a 4.2% merit increase and a 2.75% cost-of-living increase
after her quarterly review. Her new weekly salary was $788.92. What was her
weekly salary prior to the increases?
Answer:
734.1
Step-by-step explanation:
100%=788.92
4.2%=33.13
2.75%=21.69
33.13+21.69=54.82
788.92-54.84=734.1

Claude has 7 paintings and he can paint 2 every week.
Clint has 10 paintings and he takes 2 weeks to paint
1 picture. How many weeks (w) will it be before Claude
has as many paintings as Clint?
Representing the word problem as an equation, it will take 2 weeks for them to have the same number of painting.
Representing the problem with equationnumber of weeks = w
Claude's painting after w weeks can be written thus ;
7 + 2w
Clint's painting after w weeks can be written thus ;
10 + 0.5w
Equating both expression:
7 + 2w = 10 + 0.5w
Collect like terms :
2w - 0.5w = 10 - 7
1.5w = 3
w = 3/1.5
w = 2
Hence, it will take 2 weeks for them to have the same number of painting.

after 7 years, an initial investment of $600 earned $84. Find the interest rate
Answer:
2%
Step-by-step explanation:
Solving our equation
r = 84 / ( 600 × 7 ) = 0.02
r = 0.02
converting r decimal to a percentage
R = 0.02 * 100 = 2%/year
The interest rate required to
accumulate simple interest of $ 84.00
from a principal of $ 600.00
over 7 years is 2% per year.

Kind of confused, can someone help?
A DVD with a radius of 6 centimeters rotates at a speed of 243 revolutions per minute. Find the liner speed in centimeters per second.
Answer:
152.7 cm/s
Step-by-step explanation:
The radius of DVD, r = 6 cm
The angular speed of DVD, [tex]\omega=243\ rev/min=25.45\ rad/s[/tex]
We need to find the linear speed of the DVD.
The relation between linear speed and angular speed is given by :
[tex]v=r\omega\\\\v=0.06\times 25.45\\\\v=1.527\ m/s[/tex]
or
v = 152.7 cm/s
So, the linear speed of the DVD is 152.7 cm/s.
factorise 3(x-y)^2 - 2(x-y)
Answer:
[tex](x - y) [3(x - y) - 2][/tex]
Step-by-step explanation:
[tex]3(x - y)^{2} - 2(x - y)[/tex]
Lets take [tex](x - y)[/tex] common from the expression.
[tex]=> (x - y) [3(x - y) - 2][/tex]
The factors of the expression 3(x - y)² - 2(x - y) will be (3x - 3y - 2) and (x - y).
What is factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The expression is given below.
⇒ 3(x - y)² - 2(x - y)
Simplify the expression, then we have
⇒ 3(x - y)² - 2(x - y)
⇒ (x - y)[3(x - y) - 2]
⇒ (x - y)(3x - 3y - 2)
The factors of the expression 3(x - y)² - 2(x - y) will be (3x - 3y - 2) and (x - y).

given f(x)= 1/3(4-x)^2, what is the value of f(16)
Answer:
48
Step-by-step explanation:
f(x)= 1/3(4 - x)^2
f(16) = (1/3)(4 - 16)^2
f(16) = (1/3)(-12)^2
f(16) = (1/3)(144)
f(16) = 48
The value of [tex]f(16)[/tex] is 48.
Solve: [tex]f(x)=1/3(4-x)^2[/tex],
Solution:
1. Write the equation
[tex]f(x)= 1/3(4 - x)^2[/tex]
2. Substitute 16 into the x
[tex]f(16) = (1/3)(4 - 16)^2[/tex]
3. Simplify
[tex]f(16) = (1/3)(144)[/tex]
4. Multiply
[tex]f(16) = 48[/tex]
Therefore, the value of [tex]f(16)[/tex] is 48.

Use the shapes to answer the question.
Which name describes all of the shapes?
O A. parallelogram
O B. quadrilateral
C. rectangle
D. rhombus
O E trapezoid
Answer: B. quadrilateral
Step-by-step explanation:
A quadrilateral is used to describe polygons with four sides. Polygons are two dimensional shapes that are closed. and have sides that are straight.
Parallelograms, rectangles, rhombuses, trapezoids are all four sided polygons as they are closed and have straight sides and so fall under the umbrella term for shapes with four sides, Quadrilateral.
In AABC, m_A = 45°, m_B= 89º and AC = 15. To the nearest tenth what is the measure of BA? ANSWER RN PLz!!
O A. 10
O B. 11.34
O C. 10.8
O D. 11

============================================================
Work Shown:
The triangle has the given angles A = 45 and B = 89
Let's find angle C
A+B+C = 180
C = 180-A-B
C = 180-45-89
C = 46
----------------
Segment BA, or side c, is opposite angle C
Segment AC, or side b, is opposite angle B
So we have this known info:
angle B = 89side b = 15angle C = 46Apply the law of sines to find c. Make sure your calculator is in degree mode.
sin(B)/b = sin(C)/c
sin(89)/15 = sin(46)/c
c*sin(89) = 15*sin(46)
c = 15*sin(46)/sin(89)
c = 10.7917406394501
c = 10.8

What is the inequality that represents the graph shown?
Given:
The graph of an inequality.
To find:
The inequality that represents the graph shown.
Solution:
From the given graph it is clear that the boundary line passes through the points (0,-1) and (2,0). So, the equation of boundary line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-(-1)=\dfrac{0-(-1)}{2-0}(x-0)[/tex]
[tex]y+1=\dfrac{1}{2}x[/tex]
[tex]y=\dfrac{1}{2}x-1[/tex]
The boundary line is a dashed line and the shaded portion is below the boundary line so the sign of inequality must be <.
[tex]y<\dfrac{1}{2}x-1[/tex]
Therefore, the required inequality is [tex]y<\dfrac{1}{2}x-1[/tex].
