9514 1404 393
Answer:
Repeating decimals:
3/72/938/6 = 6.3_3 (repeating 3)
Step-by-step explanation:
[tex]\dfrac{3}{7}=0.\overline{428571} \quad\text{repea}\text{ting decimal}\\\\\dfrac{2}{5}=0.4\\\\\dfrac{3}{4}=0.75\\\\\dfrac{2}{9}=0.\overline{2}\quad\text{repea}\text{ting decimal}[/tex]
The improper fraction 38/6 = 19/3 = 6 1/3. As a decimal, this is ...

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!(:

Answer:
3. 147 [tex]ft^{3}[/tex] 4. [tex]\frac{160}{3} \pi[/tex] [tex]ft^{3}[/tex]
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]

three numbers have a sum of 112. The first number is twice the second, and the third number is twice the first. What is the smallest of the three numbers?
Answer:
The second number is the smallest of the three numbers with
value n = 16.
Step-by-step explanation:
Let n represent the second number, then the first number is 2n and the third number is 4n.
so
[tex]n+2n+4n=112[/tex]
Solving for n
[tex]n+2n+4n=112[/tex]
[tex]7n=112[/tex]
[tex]\frac{7n}{7}=\frac{112}{7}[/tex]
[tex]n=16[/tex]
As n = 16 is the second number.
The first number = 2n = 2(16) = 32
The third number = 4n = 4(16) = 64
Therefore, the second number is the smallest of the three numbers with value n = 16.

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.
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

Step-by-step explanation:
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
