Answer:
Movements of tectonic plates create volcanoes along the plate boundaries, which erupt and form mountains. A volcanic arc system is a series of volcanoes that form near a subduction zone where the crust of a sinking oceanic plate melts and drags water down with the subducting crust.

Answer:
42.25/6.5=6.5 per hour
Step-by-step explanation:
Hi! I'm happy to help!
To solve this, we need to divide the amount of money by the number of hours.
You earned $42.25, over the course of 6.5 hours.
42.25/6.5
6.5
So, you earned $6.50 per hour cleaning a community park.
I hope this was helpful, keep learning! :D

16 The cost for parking at a city airport is shown in the table.
Price for first day
$16.60
For every
2
day afterwards
$9
Yuri pays $124.60 to park his car.
How many days does he park his car for?
Show your working.
Answer:
He paid $9 twelve times
12× 2= 24 days
Step-by-step explanation:
1st day = $16.60
3rd day=$ 9 (i.e for every 2days afterwards)
5th day=$ 9
Yuri pays : 124.60
124.60-16.60
= $108.00
After paying the first day he paid 108.00
108.00÷ 9 = 12
He paid $9 twelve times
12× 2= 24 days

Regular pyramid
B=
P=
H=
l=
LA=
SA=
V=
Answer:
B (Base surface area) = 16 [tex]m^{2}[/tex]
P (Perimeter of the base) = 16 m
H (Height) = 6 m
L (Not sure what L means. I assume it's the slant height??) = 6.32 m
LA (I assume lateral surface area) = [tex]50.59 m^{2}[/tex]
SA (I assume total surface area) = [tex]66.59 m^{2}[/tex]
V (volume) = [tex]32 m^{3}[/tex]
Step-by-step explanation:
Sorry if anything is wrong. It would be more helpful to put the names, instead of acronyms.
Perimeter of base=4(4)=16m
Area of base=4²=16m²
Height=6m
Slant height=6.3m
Lateral surface area=4(1/2(4)(6.3))=8(6.3)=50.54m²
Total surface area=50.54+16=66.54m²
Volume=a²h/3=4²/(6)/3=16(2)=32m³

State one form of the Law of Cosines and provide a trick for writing the other two forms and explain when Law of Cosines should be used to solve a triangle.
Solving for Angles
[tex]\displaystyle \frac{a^2 + b^2 - c^2}{2ab} = cos∠C \\ \frac{a^2 - b^2 + c^2}{2ac} = cos∠B \\ \frac{-a^2 + b^2 + c^2}{2bc} = cos∠A[/tex]
* Do not forget to use the inverse function towards the end, or elce you will throw your answer off!
Solving for Edges
[tex]\displaystyle b^2 + a^2 - 2ba\:cos∠C = c^2 \\ c^2 + a^2 - 2ca\:cos∠B = b^2 \\ c^2 + b^2 - 2cb\:cos∠A = a^2[/tex]
You would use this law under two conditions:
One angle and two edges defined, while trying to solve for the third edgeALL three edges defined* Just make sure to use the inverse function towards the end, or elce you will throw your answer off!
_____________________________________________
Now, JUST IN CASE, you would use the Law of Sines under three conditions:
Two angles and one edge defined, while trying to solve for the second edgeOne angle and two edges defined, while trying to solve for the second angleALL three angles defined [of which does not occur very often, but it all refers back to the first bullet]* I HIGHLY suggest you keep note of all of this significant information. You will need it going into the future.

simply this equation
Answer:
b= x
Step-by-step explanation:
[tex]\boxed{ {x}^{m} \times {x}^{n} = {x}^{m + n} }[/tex]
Applying the law of indices above:
[tex]b = {x}^{ \frac{1}{4} } \times {x}^{ \frac{3}{4} } [/tex]
[tex]b = {x}^{ \frac{1}{4} + \frac{3}{4} } [/tex]
[tex]b = {x}^{ \frac{4}{4} } [/tex]
[tex]b = {x}^{1} [/tex]
∴b= x
Answer:
It is b = x
Step-by-step explanation:
From law of indices:
[tex] {a}^{b} \times {a}^{c} = {a}^{(b + c)} [/tex]
for, multiplication: same coefficients, we sum up the powers.
[tex]b = {x}^{ \frac{1}{4} } \times {x}^{ \frac{3}{4} } \\ b = {x}^{( \frac{1}{4} + \frac{3}{4} ) } \\ b = {x}^{ \frac{4}{4} } \\ b = {x}^{1} \\ b = x[/tex]
Find three consecutive even numbers
such that the sum of three times the
smaller number and five times the larger
number is 40 more than twice the median
number.
Answer:
1, 4, 9
Step-by-step explanation:
1 x 3 = 3
9 x 5 = 45
total = 48
median = 4
twice median = 4×2
= 8
sum = 8 + 40 = 48
48=48
simplify -2(x-4)-8(6-8x)
The simplified form of the expression is 2(31x-20).
Given the expression is -2(x-4)-8(6-8x).
Expressions in mathematics are mathematical statements containing at least two terms containing numbers or variables or both connected by an intermediate operator.
The given expression is solved by using the distributive property a(b+c)=ab+bc, we get
-2(x-4)-8(6-8x)=-2x-4(-2)-8(6)-8(-8x)
-2(x-4)-8(6-8x)=-2x+8-48+64x
Now, we will simplify the above expression by adding or subtracting like terms, we get
-2(x-4)-8(6-8x)=62x-40
-2(x-4)-8(6-8x)=2(31x-20)
Hence, the simplified form of the given expression -2(x-4)-8(6-8x) is 2(31x-20).

The sum of three numbers is 62. The second number is triple the first, and the third is six more than the
second. Find the numbers.
Answer:
The numbers are 8, 24 and 30
Step-by-step explanation:
Let x be the first number.
If the second number is triple the first, then the second number is 3x
If the third number is the second number plus six, then the third number is 3x + 6
So therefore the equation is:
[tex]x + 3x + (3x + 6) = 62[/tex]
Solving for x,
[tex]x + 3x + 3x + 6 = 62\\7x = -6 + 62\\7x = 56\\x = 8[/tex]
But why is the second number 24?
[tex]3x = 24\\3(8) = 24\\24 = 24[/tex]
And why is the third number 30?
[tex]3x + 6 = 30\\24 + 6 = 30\\30 = 30[/tex]

How Does 2 / 0.1 become 20?
The decimal value 0.1 converts to the fraction 1/10
This is because the 1 in 0.1 represents "one tenth", as its in the tenths place.
So this means 2/0.1 is the same as 2/(1/10) or [tex]2 \div \frac{1}{10}[/tex]
Then we can follow these steps:
[tex]2 \div \frac{1}{10} = \frac{2}{1} \div \frac{1}{10}\\\\\\2 \div \frac{1}{10} = \frac{2}{1} \times \frac{10}{1}\\\\\\2 \div \frac{1}{10} = \frac{2*10}{1*1}\\\\\\2 \div \frac{1}{10} = \frac{20}{1}\\\\\\2 \div \frac{1}{10} = 20\\\\\\[/tex]
Note in the second step, we flip the second fraction to go from a division problem to a multiplication problem. The general rule is [tex]\frac{A}{B} \div \frac{C}{D} = \frac{A}{B} \times \frac{D}{C}[/tex]. The first fraction does not flip.
