Find the slope of a parallel line and the slope of a perpendicular line.
y=12x-1
Step-by-step explanation:
12x - y = 1
slope of m1 = - coefficient of x / coefficient of y
= - 12 / -1
= 12
# when it is parallel;
m1 = m2
12 = m2
# when it is perpendicular;
m1 * m2 = -1
12 * m2 = -1
m2 = -1 / 12

The wheel of a bicycle has a diameter of 70cm and makes 2revolutions per second.calculate to one decimal place the speed of the bicycle in km/h
Answer:
Step-by-step explanation:
Number of reveloutions made in 1 second = 2
Number of revolutions made in 60 seconds ( 1 minute) = 2*60 = 120
Number of revolutions made in (60 minutes) 1 hour = 120 *60 = 7200
Circumference of circle = πd
[tex]= \dfrac{22}{7}*70\\\\\\= 22*10\\\\= 220 cm[/tex]
The distance traveled in 1 revoultion = the circumference of the cirlcle
= 220 cm
The distance travelled in 7200 revoultion = 7200 * 220
=1584000 cm
= 1584000 ÷ 100000
= 15.84 km
= 15.8 km
Speed = 15.8 km/h

Answer:
mode = 6
range = 7
Step-by-step explanation:
To easily find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode!
The range is the difference between the smallest and highest numbers in a list or set. To find the range, first put all the numbers in order. Then subtract (take away) the lowest number from the highest. The answer gives you the range of the list.
A travelling wave is given by the equation y = 0.03 Sin (2.2 x - 3.5t) where y and x are in metres and t is in seconds. Find the amplitude, the wayelength, the frequency, the period and the speed of the wave.
Answer:
Amplitude 0.03m, wavelength 2.86m, frequency 0.57Hz, period 1.8s
Step-by-step explanation:
The traveling wave is described with the following equation:
[tex]y=Asin(kx-wt)[/tex]
y=0.03sin(2.2x−3.5t)
A=0.03m
λ=2π/k=2π/2.2≈2.86m
T=1/f≈1.8s

find the vertical asymptote(s).
Answer:
x = 1
Step-by-step explanation:
To find the vertical asymptote(s) we set the denominator to 0, but first we have to factor and simplify the function
[tex]f(x)=\frac{(x+1)(x-7)(x+10)}{(x-1)(x-7)(x+10)}[/tex]
step 1 the function is already factored so we just have to simplify it by canceling like terms
[tex]f(x)=\frac{x+1}{x-1}[/tex]
step 2 set denominator to 0 and solve for x
x - 1 = 0
step 3 add 1 to both sides
x = 1
Answer: x = 1
By "doing the math" from the function given:
Given:
[tex]f (x) =\displaystyle \frac{(x+1)(x-7)(x-10)}{(x-1)(x-7)(x-10)}[/tex]
Terms in both the numerator and denominator are equal to 1:
[tex]f (x) =\displaystyle \frac{(x+1)}{(x-1)}[/tex]
We cannot have a denominator equal to 0, because you cannot divide by 0, so the vertical asymptote is x = 1 since 1 - 1 = 0. This can also be found by setting the denominator equal to 0 and solving for x.
By graphing:
A vertical asymptote, put simply, is a vertical line "within" the domain, but not a part of the graph. I will graph the equation given and see what we come up with.
-> See attached
Either way, the answer to your problem is:
x = 1

Step-by-step explanation:
multiply 2 5/8 times - 2 3/5 what is the answer
Step 1: Change the Mixed Numbers into Improper Fractions
---To do so, multiply the number by the denominator and add that product to the numerator.
2 x 8 = 16 + 5 = 21
21 / 8
2 x 5 = 10 + 3 = 13
13 / 5
Step 2: Multiply the Improper Fractions
---When multiplying fractions, multiply straight across (numerator x numerator and denominator x denominator).
21 / 8 x 13 / 5 = (21 x 13) / (8 x 5) = 273 / 40
Step 3: Simplify
---Change the improper fraction back into a mixed number a simplify if necessary.
40 x 6 = 240
273 - 240 = 33
6 33/40
Answer: 6 33/40

The blue dot is at what value on the number line? -3 -1
Answer:
+2
Step-by-step explanation:
I need help with 20.
Step-by-step explanation:
why ? you did it right there already.
the numerator is the top part of the fraction, the "counting" part (how many units of a certain type or size are there).
the denominator (the bottom part) is defining the type or size of units described by the fraction.
so, we are adding 4 to the numerator of 2/5, making it (2+4)/5 = 6/5
what do we need to add to the denominator (the bottom part) to make the fraction have the value of 1/2 ?
so, what x would make 6/x = 1/2 ?
6 = x/2
x = 6×2 = 12
so, we need to get 12 in the denominator, where we have currently 5.
therefore, we need to add 12-5 = 7 to it.
so that
6/(5+7) = 6/12 = 1/2
6+8 divided by 2 simplify the expression

Answers:
T-shirt = $25
Shorts = $15
Books = $50
Shoes = $30
Cell phones = $750
===============================================
Explanation:
Taking 10% of a number is simply moving the decimal point over one spot to the left.
For example, the selling price of a t-shirt is $250.00 and taking 10% of this gets us to $25.00
As another example, 10% of 150.0 is 15.0
If a whole number ends with a 0, then taking 10% of the number means we chop that zero off.
A set of cubes, each with sides 1 cm long, is stacked 5 cubes high, 8 cubes deep and 7 cubes long.
How many cubes are in the set?
Answer:
280 Cubes
Explanation:
This problem has to do with volume. To find the number of cubes in the set, you multiply the length, width, and height of all the cubes. This would look like 7*8*5. This equals 280 cubes.
Of the 200 cows in the herd, five-eighths grazed in the field. The rest slept near the barn. How many grazed in the field and how many were sleeping near the barn?
Answer:
125 barn 75 sleeping
Step-by-step explanation:
5/8 of 200 cows
of means multiply
5/8 x 200 = 1000/8 = 125
125 cows grazing
200-125 = rest of cows
75 = rest of cows sleeping
In a group of 50 patrons, 14 patrons like lattes and espressos, 11 patrons like
espressos and cappuccinos, 7 patrons like lattes and cappuccinos, and 3
patrons like all 3 coffee drinks. Altogether, 22 patrons like lattes, 30 patrons
like espressos, and 23 patrons like cappuccinos. How many patrons don't like
any of these coffee drinks?
Answer:
B
Step-by-step explanation:
This problem can be solved using a venn diagram! Just draw bubbles and the common numbers! I attached an image below!
With these numbers we can see how many there are in common. By subtracting the common numbers we get that there are 4 that don't like any. So the answer is B.
