Can units subtract themselves in mathematics? Example is cm²-cm =cm? / m³-m =m²?
Answer:
No, they cannot be added or subtracted.
Step-by-step explanation:
According to the homogenity of units and dimensions, the quantities of the same units and dimensions are added or subtracted only.
So, the quantities of different units and dimensions can not be added or sutracted.
So,
[tex]cm^2 - cm = notdetremined[/tex]

Answer:
B. substitute for X in first equation
solve for x, show work please!! 20 points.
Step-by-step explanation:
Here,
13x - 5 = 11x + 15. [Since corresponding angles are similar in parallel lines]
=> 13x - 11x = 15 + 5
=> 2x = 20

Use the formula A=bhto find the area of the parallelogram.
2.1 m
6.3 m
Answer:
A = 13.23 m²
Step-by-step explanation:
A = bh
Where,
A = area of the parallelogram
b = base of the parallelogram
h = height of the parallelogram
From the question, assume
b = 2.1 m
h = 6.3 m
A = bh
= 2.1 m × 6.3 m
= 13.23 m²
A = 13.23 m²

Answer:
AC = 3.76
Step-by-step explanation:
take 70 degree as reference angle
using sin rule
sin 70 = opposite / hypotenuse
0.939 = AC /4
0.939 * 4 = AC
3.756 = AC
3.76 = AC
Answer:
AC = 3,76
Step-by-step explanation:
Sin70 = AC/AB
Sin 70 = AC/4
AC = Sin70×4
AC = 3,76

A group of students is traveling to a baseball game on a rented bus. The cost to rent the bus is $100 and each ticket to the game costs $15.
The students decide that the cost per person should be less than $25.

c

р
OD
100+15p
P
<25
Answer:
100+15p < 25p
Step-by-step explanation:
Note that
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
total cost of travelling = cost to rent a bus + total cost of ticket for p persons
100 + 15p
they want to spend less than an average cost of 25 per p people
they want to spend less than 25p
since they dont want to spend less than 25p, < would be used
100+15p < 25p

Given the building layout for Store A, Store B, Store
C, and Store D, what portion of the shared $6000
security costs should be apportioned to Store B if store A is 2500ft^2, store B is 625ft^2, store C is 625^2, and store D is 2500ft^2
Answer:
$600
Step-by-step explanation:
2500+625+625+2500=6250
625/6250=.10 or 10%
6000 x .10=600
Store B should be apportioned $600 of the shared $6000 security costs.
To apportion the shared $6000 security costs to each store based on their square footage, we need to calculate the total square footage of all the stores and then determine the proportion of each store's square footage to the total square footage.
[tex]Total square footage = 2500ft^2 (Store A) + 625ft^2 (Store B) + 625ft^2 (Store C) + 2500ft^2 (Store D)[/tex]
[tex]Total square footage = 6250ft^2[/tex]
Now, let's calculate the proportion of Store B's square footage to the total square footage:
[tex]Proportion of Store B = Square footage of Store B / Total square footage\\Proportion of Store B = 625ft^2 / 6250ft^2[/tex]
Now, find the proportion in decimal form:
[tex]Proportion of Store B = 625 / 6250\\Proportion of Store B = 0.1[/tex]
To determine the portion of the security costs for Store B, multiply its proportion by the total security costs:
Portion of security costs for Store B = Proportion of Store B * Total security costs
[tex]Portion of security costs for Store B = 0.1 * $6000\\Portion of security costs for Store B = $600\\[/tex]
Therefore, Store B should be apportioned $600 of the shared $6000 security costs.

Find the volume of the composite figure
Answer:
540m^3
Step-by-step explanation:
find volume of top + volume of bottom
bottom: l*w*h = 16*5*4 =300 m^3
top = area of side times width = area of triangle times width
area of triangle is 1/2*b*h = (6*16)/2 = 48 m^2
multiply by width = 48*5=240m^3
add top and bottom = 300+240=540m^3

Answer:

Explanation
90+38+x+1.3=180
90+38
Add these numbers
=128
128+x+1.3=180
128+x+1.3
Add these numbers
128+1.3=129.3
129.3+x
129.3+x=180
129.3+x
sort elements
x+129.3=180
129.3
convert this to a fraction
1293/10
x+1293/10=180
x+1293/10=180
Move each term from the right to the left side and change a sign of every element
x+1293/10-180=0
x+1293/10-180
subtract these number
1293/10-180=1293/10-1800/10
=-507/10
x-507/10=0
f (x)=x-507/10
a=1
b=-507/10
x-507/10=0
move each number from the left a the right side and change a sign of every element
x=507/10
therefore x=50.7
is 6,7,13 a right triangle
Answer:
No
Step-by-step explanation:
For a right triangle, according to the Pythagorean Theorem, the 2 sides squared must equal the hypotenuse squared. ([tex]a^{2} +b^{2} =c^{2}[/tex])
The hypotenuse is the longest side so [tex]13^{2}=169[/tex]
[tex]6^{2}=36\\7^{2}=49[/tex]
36 + 49 does not equal 169
What are the domain and range of the function?
Answer: Domain: (-inf,inf) Range; [-4,inf)
Step-by-step explanation: Domain is x values possible and range is y values possible. Quadratics always have a domain of (-inf,inf) and the range starts from -4 going up infinitely. and if -4 is included then we use a bracket therefore, [-4,inf). Also, infinity always has a parenthesis.

If the measure of 1 is 120°. That is the measure of 2
Answer:
60
Step-by-step explanation:
straight lines are 180
since all lines are parallel
180 - 120 = 60
For the given set of parallel lines measurement of angle 2 is equals to 60degrees.
What are parallel lines?" Parallel lines are defined as coplanar lines which do not intersect in the same plane. They are equidistant from each other in the same plane."
According to the question,
Given,
Line 'n' is parallel to line 'm'
Line 's' is parallel to line 't'
As diagram drawn we have,
AB is a part of line 'n'
BC is a part of line 't'
CD is a part of line 'm'
DA is a part of line 's'
From this we get,
AB parallel to CD
BC parallel to DA
Therefore,
ABCD is a parallelogram.
Opposite angles in a parallelogram are congruent we have,
∠1 ≅∠3 = 120°
∠2 and ∠3 are supplementary angles.
⇒∠2 + ∠3 = 180°
⇒∠2 + 120° = 180°
⇒∠2 = 180° - 120°
⇒∠2 = 60°
Hence, for given parallel lines measure of angle2 is equals to 60degrees.

Answer:
56 tests
Step-by-step explanation:
first find the amount of test he took each week. if we divide 12 by 6 (12 ÷ 6 = 2) we find out that he took 2 tests per week.
So if he continues with the same rate for the next 28 weeks of school, in order to find out how many tests he would have taken, we just need to multiply 28 by 2 (28 × 2 = 56), which will be equal to 56
