1. Which expression is equivalent to 60m 2n6 for all values of m and n where the 5m-on-2 expression is defined? A. 12mns 12n B D. 55m?n mo
Given:
The expression is:
[tex]\dfrac{60m^{-2}n^6}{5m^{-4}n^{-2}}[/tex]
To find:
The equivalent expression.
Solution:
We have,
[tex]\dfrac{60m^{-2}n^6}{5m^{-4}n^{-2}}[/tex]
It can be written as:
[tex]=\dfrac{60}{5}\times \dfrac{m^{-2}}{m^{-4}}\times \dfrac{n^6}{n^{-2}}[/tex]
[tex]=12\times m^{-2-(-4)}\times n^{6-(-2)}[/tex] [tex][\because \dfrac{a^m}{a^n}=a^{m-n}][/tex]
[tex]=12\times m^{-2+4}\times n^{6+2}[/tex]
[tex]=12m^{2}n^{8}[/tex]
Therefore, the correct option is A.

HELP IM DOIN A MATH TEST AND IM STUCK!!!!! Tim knows the volume In bass area of a wooden chest that is in the shape of a rectangular prism. If the volume is 5/24 Of a cubic unit and the base area is 1/5 of a square unit, What is the height of the chest?
Answer:
Height is 1 1/24 unit.
Step-by-step explanation:
Given:
volume = 5/24 unit³
base area = 1/5 unit²
Rectangular prism:
volume = length * width * height
base area = length * width
Volume = base area * height
height = volume / base area
h = 5/24 ÷ 1/5
h = 5/24 * 5/1 = 5*5 /24*1 = 25/24 = 1 1/24 unit

Find the volume of a cone with a height of 6cm and a base radius of 4cm. Use the value 3.14 for π, and do not do any rounding.
Answer:
100.48 cm³
Step-by-step explanation:
Volume of a cone, V = 1/3 * pi * r² * h
Radius, r = 4 cm ; h = 6cm
V = 1/3 * 3.14 * 4² * 6
V = 1/3 * 3.14 * 16 * 6
V = 3.14 * 16 * 2
V = 3.14 * 32
V = 100.48 cm³
Hence, the volume of the cone is 100.48 cm³

What's the answer to 10-10x100-23? I got -1013, and the one is screaming that it's wrong.
Answer:
ur right
it's -1013
bc you need to do multiplication first so the equation turns out to be
10 - 1000 - 23
so then that turns to -1013 if you calculate left to right

For the graph - just copy my graph
Step-by-step explanation:
The equations are fully simplified already so all we have to do is graph them and find the solution
The solution being where the two lines graphed intersect
As you can see in the graph below the two lines intersect at point (2,1) therefore the solution to the system of equations is (2,1)

Answer:
The angle between the ramp and the horizontal is 11.54 degrees
Step-by-step explanation:
Here, we want to get the angle between the ramp and the horizontal
What we have to do here is to bring the measure of 2 m near to the edge leftwards, so we can have a right triangle
Now, the angle we want to calculate is the angle that faces the measure 2 m
The given measure of 10 m will represent the hypotenuse of the right triangle
The trigonometric ratio that links the hypotenuse and the opposite is the sine
The sine is the ratio of the opposite to the hypotenuse
Thus, we have it that;
sin theta = opp/hyp
sin theta = 2/10
sin theta = 0.2
theta = sin^-1 0.2
theta = 11.54

Awad claims that when m is a negative integer and n is a positive integer, n - m is always negative. Is Awad’s claim true or false? Explain your reasoning. If it is true, give an example to support his claim. If it is false, give a counterexample. Explain your reasoning..
Answer:
False
Step-by-step explanation:
False, because whenever you subtract a negative number, you always end up adding because two negatives make a positive. Lets say n is 4 and m is -3, 4-(-3) is going to turn into 4+3=7.
The Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.
Awad claims that when m is a negative integer and n is a positive integer, n - m is always negative.
The above claim is false because subtracting a negative integer always results in an addition because two negatives equal a positive.
For example, n is 6 and m is -2; 6 -(-2) will equal 6 + 2 = 8.
Hence, the Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.

Prove Quadrilateral P(-2, 3) L( 2, 6) U (7,6) S(3, 3) is a rhombus
Answer:
The quadrilateral is a rhombus
Step-by-step explanation:
Prove Quadrilateral P(-2, 3) L( 2, 6) U (7,6) S(3, 3) Is a rhombus
A rhombus is a quadrilateral with all its sides equal to each other.
We prove this using the formula
√(x2 - x1)² + (y2 - y1)²
When given vertices (x1, y1) and (x2, y2)
For sides PL
P(-2, 3) L( 2, 6)
√(2 - (-2))² + (6 - 3)²
= √4² + 3²
= √16 + 9
= √25
= 5 units
For sides LU
L( 2, 6) U (7,6)
√(7 - 2)² + (6 - 6)²
= √5²
= √25
= 5 units
For side US
L( 2, 6) U (7,6)
= √(7 - 2)² + (6 - 6)²
= √5² + 0²
= √25
= 5 units
P(-2, 3), S(3, 3)
= √(3 - (-2))² + (3 - 3)²
= √5² + 0²
= √25
= 5 units
From the above calculation,
PL = LU = US = PS = 5 units
Hence, the above quadrilateral is a rhombus
An airport has enough space for 16 planes to park. There are 9 planes parked at the airport right now.
Let x represent how many more planes can park at the airport. Write an inequality that best describes the problem?
Answer: x=16-9

hi can someone help me with this?
Answer:
h = 4.5 units
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here A = 6.75 and b = 3 , then
[tex]\frac{1}{2}[/tex] × 3h = 6.75
1.5h = 6.75 ( divide both sides by 1.5 )
h = 4.5
we have
base [b]=3 units
height [h]=x units
area of triangle =6.75 square units
we have
area of triangle =1/2 b×h
6.75 square units =1/2×3×x
x=6.75×2/3=4.5units
so height is 4.5 units.

After 20,% discount a mobile set is bought at rupees 13920 find the marked price of the mobile set. Maths question
Step-by-step explanation:
First of all, let us lay down the clues;
●There is a 20% discount on the mobile set.
●The price after the discount is Rs 13 920
●We need to find the original price.ie.(100% stands for original price)
Now let's start;As there is a 20% Discount on the m.Set, we need to find the exact percentage decrease.
So,
100%-20%= 80%
Now let's do Direct Proportion,
80%= Rs 13 920
1%= 13 920/80
100%= 13 920/80*100=Rs 17 400
Your FINAL ANSWER;RS 17 400

Find the area of the regular polygon. Round your answer to the nearest whole number of square units.
Answer:
total area = 39.6 square units
Step-by-step explanation:
determine the inside angle
360 / 5 = 72°
half of the triangle = 36°
given:
adj = 3.3
Ф = 36°
length of the opp of a small triangle is = adj. tan Ф
opp = 3.3 * tan 36 = 2.4
area of a triangle = 1/2 b * h x 2 tringles
area =( 1/2 * 2.4 * 3.3 ) * 2
area = 7.92 multiplied by 5 equal shapes
total area = 7.92 * 5
total area = 39.6 square units
hope this helps
mark me as a brill please
good luck
The total area of the regular polygon should be considered as the 39.6 square units.
Calculation of the total area of the regular polygon:But before that following things should be calculated
first determine the inside angle i.e.
[tex]= 360 / 5[/tex]
= 72°
Now
half of the triangle = 36°
Since
adj = 3.3
Ф = 36°
So,
opp =[tex]3.3 * tan 36[/tex] = 2.4
Now
area of a triangle =[tex]1/2 b * h * 2[/tex]
[tex]=( 1/2 * 2.4 * 3.3 ) * 2\\\\= 7.92 * 5[/tex]
= 39.6 square units
hence, The total area of the regular polygon should be considered as the 39.6 square units.
