Answer:
x=30⁰
Step-by-step explanation:
4x-55+3x+25=180
7x-30=180
7x=210
x=30⁰
Proof
3(30)+25=115
4(30)-55=65
115+65=180⁰
A dishwasher is priced at $685. There is an 8% sales tax rate. What is the sales tax of the dishwasher in dollars and cents?
Answer:
The tax would be $54.80 !
Step-by-step explanation:
To do the problem you have to cross multiply and divide.
[tex]\frac{x}{685} = \frac{8}{100}[/tex]
685 x 8 = 5480
5480 / 100 = 54.8
Explain what each variable in the linear equation y=mx+b represents.
y represents _________________
m represents ________________
x represents _________________
b represents _________________
Answer:
y = dependent variable
m = slope of a line
x = independent variable
b = y-intercept
the equation y + 1 = 5(x + 6) equivalent to
Step-by-step explanation:
y + 1 = 5(x + 6)
y + 1 = 5x +30
y = 5x +30 -1
y = 5x + 29

Lacey pays $15 for each hour of golf lessons and $10 for equipment rental. If the lesson is more than 3 hours long, she only pays $5 for equipment rental. Is the total cost of Lacey's lesson a function of the number of hours scheduled?
Answer:
Yes, the total cost of Lacey lesson is a split function of hours scheduled
Step-by-step explanation:
The amount Lacey pays for each hour of golf = $15
The amount Lacey pays for equipment rental = $10
The amount Lacy pays for equipment rental for a 3 hours long lesson = $5
Therefore, we have
Let C represent the total cost of Lacey lesson and let t represent the number of hours, we have;
C = $10 + t × $15 for 0 ≤ t ≤ 3
C = $5 + t × $15 for t > 3
Therefore, the total cost of Lacey lesson is a split function of hours scheduled

Step-by-step explanation:
3. Volume of a square pyramid = [tex](base.edge.length)^{2}[/tex] × [tex]\frac{height}{3}[/tex]
Variables:
V = volume
x = base edge length
h = height
V = [tex]x^{2}[/tex] × [tex]\frac{h}{3}[/tex]
x = 7 ft
h = 9 ft
Plug the values in the equation:
V = [tex]7^{2}[/tex] × [tex]\frac{9}{3}[/tex]
V = 49 × 3
V = 147 [tex]ft^{3}[/tex]
4. Volume of cone = [tex]\pi r^{2} \frac{h}{3}[/tex]
Variables:
V = volume
r = radius
h = height
V = [tex]\pi r^{2} \frac{h}{3}[/tex]
r = 8ft /2 = 4 ft (radius is half of the diameter)
h = 10 ft
V = [tex]\pi 4^{2} \frac{10}{3}[/tex]
V = [tex]\pi[/tex] × 16 × [tex]\frac{10}{3}[/tex]
V = [tex]\frac{160}{3} \pi[/tex] [tex]ft^{3}[/tex]

Step-by-step explanation:
a washer and dryer cost $657 combined. The washer costs $43 less than the dryer. What's the cost of the dryer?
Answer:
The answer is $614
w + d = 657
657 divided by 2 is 328.5
328.5 - 43 285.5 (that would be washer)
Answer: 657 - 285.5 = 371.5
that should be right!(:

Describe the transformation that takes f(x) = x+1 to g(x) = -x+4.
Answer:
Reflecting over the x-axis, vertical movement up 3 units.
General Formulas and Concepts:
Algebra I
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptTransformations of graphs
Step-by-step explanation:
Step 1: Define
f(x) = x + 1
g(x) = -x + 4
Step 2: Define
Multiplying -1 to x flips it over the x-axis, or known as a reflection. There is no vertical shrink/stretch.
To get to 1 to 4, we add 3. That means we will be moving the graph up 3 units.
Answer:
The sign on the 'x' changes, this implies a reflection.
g(x) = -f(x) = -(x+1) = -x -1
Now apply a vertical translation 'up 5' to f(x)
g(x) = -f(x) + 5 = (-x-1) +5 = -x +4

SOMEONE HELP! I know the answer I just need to show the work.
What is the measure of
angle b?
Answer: 36
okay so
117° + angle a = 180° (supplementary angle)
angle a = 180 - 117
= 63°
then angle a + angle b + 81° = 180° ( angle sum property)
so... 63° + angle b + 81° = 180
144 + angle b = 180°
angle b = 180 - 144
= 36°
hope this helps.
