The cost of pen and colored pencils per piece is =10.85
The new total length of both Betty and Beth is =227.2cm
Total number of pens Randy needs to buy = 5
Total number of colored pencils Randy needs to buy= 3
The both items are bought at the same prize = a
The cost of five pens is = 5× a = 5a
The cost of colored pencils is = 3 × a= 5a
The money needed to spend on the items= 86.78
To find the cost of each item which is a ,
5a + 3a = 86.78
(5+3) a= 86.78
8a = 86.78
therefore a = 86.78/8
= 10.85
Therefore the prize of each item is = 10.85. That is option B
Betty's height = 119.2 cm
Beth's height = 105.6cm ( which remained the same)
But Betty's height after 6 months = (6× 0.4) + 119.2
= 2.4 + 119.2
= 121.6 cm
Therefore, the total new height= 121.6 + 105.6
= 227.2cm
That is option A.

Answer:
the answer is 7.2 cm
Step-by-step explanation:
14^2 is 196
12^2 is 144
196 - 144 = 52

Answer:
31
Step-by-step explanation:
sum of the bordering angles is 180° so
(5x-16) + (x+10) = 180
5x - 16 + x + 10 = 180
6x - 6 = 180
6x = 186
x = 186 ÷ 6
x = 31
Answer:
The answer is x=31.
5x-16+x+10=180
6x-6=180
6x=186
x=31
Then, 5(31)-16=
155-16= 139
Also, x+10=
31+10=41
Solution check:
139+41=180, so x=31 is correct.
is a/b +b/c rational number
Answer:
Yes.
Step-by-step explanation:
Yes.
Assuming a, b and c are integers (not = 0)
a/b + b/c
= (ac + b^2) / bc which is a rational number.

3. Find the slope of the line passing through the points (-4,-8) and (2,-8)
2. Find the slope of the line passing through the points(6,6) and (6,-4)
Answer:
2. undefined
3. 0
Step-by-step explanation:
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
3.
( x1, y1 ) = ( - 4, - 8 )
Here,
x1 = - 4
y1 = - 8
( x2, y2 ) = ( 2, - 8 )
Here,
x2 = 2
y2 = - 8
Slope = ( - 8 - ( - 8 ) ) / ( 2 - ( - 4 ) )
= ( - 8 + 8 ) / ( 2 + 4 )
= 0 / 6
Slope = 0
2.
( x1, y1 ) = ( 6, 6 )
Here,
x1 = 6
y1 = 6
( x2, y2 ) = ( 6, - 4 )
Here,
x2 = 6
y2 = - 4
Slope = ( - 4 - 6 ) / ( 6 - 6 )
= - 10 / 0
Slope = not defined
Note : -
Any number who denominator is 0 is undefined.

Answer:
Mr. Pandya's class has 12 boys and 18 girls.
Mr. Chapman's class has 5 girls and 25 boys.
Step-by-step explanation:
The graph of y=f(x) is shown below. find all the values of x where f(x)=4
f(x) = 4 means "y=4".
If you draw in y=4 as a line on the graph, you're looking for points where the f(x) graph hits y=4. (see picture below)
This happens at one point and the x-value of that point is -2.
-2 is the only x-value where this happens.
Find x (in degrees) in the following quadrilateral.
Answer:
x = 110°
Step-by-step explanation:
The sum of the interior angles in a quadrilateral is 360°. This means:
x + x + x - 30 + 1/2x + 5 = 360° - we can simplify this
3 1/2x - 25 = 360° - now add 25 to both sides
3 1/2x = 385 - finally divide both sides by 3 1/2
x = 385 ÷ 3.5 = 110
x = 110°
Hope this helps!

How would Newton’s second law of motion impact the fitness routine of someone who is significantly overweight? Is there any type of fitness activity that a significantly overweight person could do where Newton’s second law of motion would not be a factor?
Answer: The rate of change of momentum of a body over time is directly proportional to the force applied and occurs in the same direction as the applied force.
We can write the law as:
Where F is a force, and P is the momentum.
Remember that the momentum is defined as the quantity of motion, such that:
P = M*V
Where M is the mass of the moving object and V is the velocity of the moving object.
Or we can write the second law as:
F = M*a
M = mass
a = acceleration
