Answer:
4
Step-by-step explanation:
Given the expression 2/? > 4/12, to find the value of ? that will make the expression true, we will cross multiply first
On cross multiplying:
2×12 > 4 × ?
24 > 4 × ?
Divide both sides by 4
24/4 > 4×?/4
6 > ?
This means that ? < 6
The answer will be a value that is less than 6. According to the option, the only value less than 6 is 4. Hence the correct answer is 4.
Answer: 4
Step-by-step explanation:
solve for the indicated variable A=r+rvf for v
Answer:
[tex]v = \frac{A - r}{rf}[/tex]
Step-by-step explanation:
Given
[tex]A = r + rvf[/tex]
Required
Solve for v
[tex]A = r + rvf[/tex]
Subtract r from both sides
[tex]A - r = r - r + rvf[/tex]
[tex]A - r = rvf[/tex]
Divide both sides by rf
[tex]\frac{A - r}{rf} = \frac{rvf}{rf}[/tex]
[tex]\frac{A - r}{rf} = v[/tex]
Reorder the expression
[tex]v = \frac{A - r}{rf}[/tex]
At this point, we;ve solved for v

What is the absolute value of |5+8a|=53?
Answer:
a = 6 or a = -58/8
Step-by-step explanation:
I think you meant to ask us to solve for a.
There are two cases to solve for:
5 + 8a = 53 or -(5 + 8a) = 53
8a = 48 or 5 + 8a = -53
a = 6 or 8a = -58
a = 6 or a = -58/8

Laura says that the distance between (4,-2) and (4,-7) in the coordinate plane is equal to |-2-(-7)|units Ryan say that the distance between (2,3) (-9,3) in the coordinate plane is equal to |2+9| units is either Laura or Ryan correct explain
Answer:
Both are correct.
Step-by-step explanation:
In the point (4,-2) and (4,-7), the x-coordinates are same. So, the distance between these points is the absolute difference between the y-coordinates of these points.
[tex]Distance=|-2-(-7)|=5\text{ units}[/tex]
So, Laura is correct.
In the point (2,3) and (-9,3), the y-coordinates are same. So, the distance between these points is the absolute difference between the x-coordinates of these points.
[tex]Distance=|2-(-9)|=|2+9|=11\text{ units}[/tex]
So, Ryan is correct.
Hence, both are correct.

Jason has 144 feet of material to build a fence around a rectangular garden on his property. If the width of the fence must be 9 feet, what is the length of the fence in yards if he uses all 144 feet of material
Answer:
Length = 63 feet
Step-by-step explanation:
concept used:
perimeter of rectangle = 2( length + width)
____________________________________________
Given that Jason has 144 feet of material and all is used in building fence.
It means that perimeter of fence is 144 feet.
2. Width of fence = 9 feet
let the length be x
perimeter of rectangle = 2( length + width)
then perimeter of fence will be = 2(9+x)
As given above perimeter of fence is 144 feet.
2(9+x) = 144
=> 9 + x = 144/2 = 72
=> x = 72 - 9 = 63
Length = 63 feet.
Answer:
21 yards

6. Give the slope of each line. Also, state if the lines are parallel (yes or no).
Hint: rewrite to slope intercept form.
AB: 2y + 2x = 8 and CD: y + x = 2
Slope of line AB:
Slope of line CD:
Are the lines parallel (yes or no):
Step-by-step explanation:
Hey there!!
Let me simply clear you.
Given,
AB: 2y+2x =8.
Let's take the equation in slope intercept form.
2y = -2x +8
[tex]y = \frac{ - 2x}{2} + \frac{8}{2} [/tex]
[tex]y = - 1x + 4[/tex]
Comparing the equation with y= mx+c, we get;
Therefore, slope of AB is -1.
Now,
Again, the another equation is,
y + x = 2
y = -x+2
Comparing, the equation with y = mx + c.
Therefore, slope of CD = -1
For parallel lines, m1=m2.
slope of AB (m1) = -1
slope of CD(m2)= -1
As m1= m2 {True}.
Therefore, They are parallel to eachother.
Hope it helps...

the price of gravel is $24 for every 3/8 ton. Kate wants to know the price of 2 tons of gravel. at that rate, what is the price of 2 tons of gravel
Answer:
$128Step-by-step explanation:
This problem is on rate.
firstly we have to find the rate at which 1 ton is sold
given that 3/8 ton is sold for $24
hence 1 ton will be sold for X
cross multiply
X = 24/3/8
inverse the denominator and multiply the result with the numerator we have
X= 24*8/3
X= $64
Now having found out that 1 ton cost $64
2 tons will cost =64*2
= $128
Therefore at this rate two tons will cost $128
Answer:128

Answer:
Answer: Option D.
Step-by-step explanation:
Hey there!!
Here, To find the equation of a st.line passing through point (3,1) is :
[tex](y - 1) = m1(x - 3)[/tex]
It is the first equation.
Given, Another equation is:
[tex]y = \frac{2}{3} x + 1[/tex]
It is 2nd equation.
Comparing the 2nd equation with y = mx+c we get,
Slope (m2) = 2/3.
As per the condition of parallel lines,
m1 = m2 = 2/3.
Putting, the value of m1 in equation 1st we get,
[tex](y - 1) = \frac{2}{3} (x - 3)[/tex]
or, 3 (y-1) = 2(x-3)
or, 3y - 3 = 2x - 6
[tex]y = \frac{2x - 6 + 3}{3} [/tex]
[tex]y = \frac{2}{3} x - 1[/tex]
Diving-3/3 = -1.
Therefore, y = 2/3 x - 1 is the required equation.

6) Suppose the length of your running shoe is 28.4 cm,
a) How many of your shoes would it take (heel to toe) to make 1 meter? (round to the nearest tenth)
b) How many shoes would it take to make 1 kilometer? (round to the nearest whole number)
Answer:
About 4.
Step-by-step explanation:
28.4 * 4 is equal to 113. 6, so about four shoes would be equal to a meter, since a meter is equal to 100cm.

Tiana has already taken 1 page of notes on her own, and she will take 1 page during each hour of class. In all, how many hours will Tiana have to spend in class before she will have a total of 43 pages of notes in her notebook?
Answer:
42 Hours.
Step-by-step explanation:
As an equation where y is the total pages and x is hours of class:
y=1+1x since she started with 1 page and does 1 page per hour.
Setting the total pages she needs as 43 (y=43) we get:
43=1+1x
Subtract one on both sides
42=1x
The 1 doesn't need to be written so
x=42
Therefore, it'll take her 42 hours to write all those notes.
