» [tex]\dfrac{3}{20}[/tex] convert it to decimal and percentage 62.5% convert it to decimal and fraction.
[tex]\huge{\underline{\mathfrak{Solution:-}}}[/tex]
For converting [tex]\dfrac{3}{20}[/tex] into decimal simply divide 3 by 20= [tex]\dfrac{3}{20}[/tex]
= 3 ÷ 20
= 0.15
Now,
For the second part , let us convert the fraction 62.5% into decimal firstWe know that,
Any number in percentage like, 62.5% can also be written as [tex]\dfrac{625}{100}[/tex]It comes up simple now, divide 625 by 100 to obtain the decimal= 62.5%
= [tex]\dfrac{625}{100}[/tex]
= 6.25
Here, now for the fraction one,
We already have our [tex]\dfrac{625}{100}[/tex]Just make it to it's simplest form= [tex]\dfrac{625}{100}[/tex]
= [tex]\dfrac{625÷5}{100÷5}[/tex]
= [tex]\dfrac{125÷5}{20÷5}[/tex]
= [tex]\dfrac{25}{4}[/tex]
And, the answer in fraction comes [tex]\dfrac{25}{4}[/tex]

Step-by-step explanation:
You start at (1,0) And move down 2 units and left 4 units where do you end
Answer:
(-3,-2)
Step-by-step explanation:
Starting at the point (1, 0)
Now we move don 2 units (so the y-value reduces in two units) making now the point (1,0-2) which is (1, -2)
then we move to the left 4 units (so the x-value has now to be decreased in 4 units) making the point: (1-4, -2) which is (-3, -2)
Answer:
It would be -2,4.
Step-by-step explanation:
you start at (1,0) and go down 2 to -2 then left 4 you would land on -2,4

To solve such examples of we need to know about points, lines, and planes.
PointA Point can be described as an exact location in space but it has no size. A point is represented by a dot which shows the point in pictures and diagrams.
In the diagram, a line is represented by a capital letter with an arrow on the letters, such as [tex]\underset{AB}{\rightarrow}[/tex].
The examples of a point are a ball, a ball bearing, pin location on a map, etc.
LineA line is drawn when an infinite number of dots are connected together in both directions extended forever.
Examples of a line are a thread string, a wire, etc.

17 + (-31) = -48
Answer:
the positive 17 is the problem. so it should be: -17 + (-31) = -48
Step-by-step explanation:
if 17 is positive, the equation is just: -14 = -48 (which isnt correct)

change 37/7 to mixed fraction
Answer:
5 2/7
Step-by-step explanation:
First, we can find how many whole 7's would fit into 37.
We find that five 7's fit into 37.
5*7=35
37-35=2
So, our mixed number is 5 2/7
Sherie bought a beach towel that normally costs $44 but was on sale for half price. She also bought a beach hat that was on sale for $12 off. Before tax, her total cost was $38. What was the regular price of the beach hat?
$22
$28
$48
$56
Answer:
$28
Step-by-step explanation:
The towel was $44 but at 1/2 off would be $22.
Her total cost was $38 so we subtract $22 from $38 to find how much she paid for the beach hat.
$38-$22 = $16
We add $12 to $16 to find the original price of the hat.
$16+$12 = $28
Answer:
$28
Step-by-step explanation:
In the diagram, NQ is a diameter of R, mMN= (6x+33), and mNP= (5+10x). Find mMP
Answer:
MP=150
Step-by-step explanation:
MP= MN+NP
6x+33=5+10x ( NQ is the diameter)
33-5=10x-6x
28=4x
x=28/4=7
MP= MN+NP
MP=6(7)+33+5+10(7)
MP=42+38+70
MP=150

Solve by factoring:
5x^2 + 19x + 12 = 0
When solving polynomial equations, first set the equation
equal to zero, then check for a Greatest Common Factor.
Since there is no greatest common factor, this will make life a
little bit more difficult because we will have to factor the trinomial.
First, find all possible factors for constant term.
I have listed these in red below.
Make sure to reverse the factors since in each binomial,
the first term is different so we need to reverse the factors.
The factors of 5x² will just be 5x and z.
After finding factors for the constant and the leading
coefficient for your trinomial, we can eliminate some factors.
If you have an odd coefficient on the middle term,
you can eliminate any pairs of even factors.
So the group I crossed out in purple below will be eliminated.
Another strategy is to use factors a little closer together.
So I would go with the 4 and 3 group.
Surely enough, our trinomial does factor with the 4 and 3.
Now set the factored trinomial equal to 0.
Then use zero product property and you have your answer.
Answer:
-0.27
Step-by-step explanation:
5x^2=25x
25x+19x=44x
44x+12=0
-12=0-12
44x=-12
44x/44=-12/44
x=-0.27
The gravitational potential energy, ‘G’ of an object is directly proportional to its height, ‘h’ above
the surface of Earth. When the object is at a height of 40 meters above Earth, its gravitational
potential energy is 2200 joules. Find
I. An equation connecting G and h.
II. The gravitational potential energy of the object when it is at a height of 22 meters above the
surface of Earth.
III. The height of the object above the surface of Earth when it has a gravitational potential
energy of 3025 joules.
Answer:
see explanation
Step-by-step explanation:
Given that G is directly proportional to h then the equation relating them is
G = kh ← k is the constant of proportion
To find k use the condition h = 40 when G = 2200, then
2200 = 40k ( divide both sides by 40 )
55 = k
1
G = 55h ← equation of proportion
11
When h = 22, then
G = 55 × 22 = 1210 joules
111
When G = 3025, then
3025 = 55h ( divide both sides by 55 )
h = 55 m
7) Tom is deciding whether or not he should become a member of the gymſto use their basketball courts. The
membership cost is $135. Members pay $2 to rent out the basketball courts. Non-members can rent the court also, but
they have to pay $11 each time. How many times would Tom need to rent the court in order for it be cheaper to be a
member than a non member?
Answer:
15 times for it to be equal, 15+ to be cheaper
Step-by-step explanation:
135+2x=11x
135=9x
135/9=x
15=x
135+2(15)=165$
11(15)=165$
Answer:
16 times
Step-by-step explanation:
Create an inequality where x represents the number of times he rents out the court:
2x + 135 < 11x
Solve for x:
135 < 9x
15 < x
So, Tom would have to rent the court out 16 times for it to be cheaper
Given
m2 ABD is a straight angle.
m ABC = 8x - 41°
mZCBD = 9x + 17°
Find m2CBD:
А
B
D
Answer:
∠CBD = 125°
Step-by-step explanation:
The angle sum theorem tells you that ...
∠ABC +∠CBD = ∠ABD
8x -41° +9x +17° = 180° . . . . . . a "straight angle" has a measure of 180°
17x -24° = 180° . . . simpify
17x = 204° . . . . . . add 24°
x = 12° . . . . . . . . . . divide by 17
Now the measures of the angles can be found from their expressions.
∠ABC = 8(12) -41° = 55°
∠CBD = 9(12) +17° = 125°

Answer:
7) refer to d=rt triangle so answer is t= d/r
8) rearrange by dividing so it should be PV/nR = T
9) move 5r to other side which become 2p = q - 5r then divide by 2. final answer is p = q-5r/2
10) multiply both side by b/1 so b got cancel on left side
right side become c(b/1) which is same as cb
then you divide both side by c to isolate b on the right side
final answer is a/c=b

This illustrates a shortcut for multiplying by 9 that can be convenient for mental arithmetic. The idea is to multiply by 10, which just involves adding 0 (or moving the decimal point), then subtract the original number.

Answer:
g(x) = x - 7
Step-by-step explanation:
g(x) is the same as saying "y".
you need to move the y-intercept down 7 units, therefore putting the term - 7 into the expression.
Answer:
g(x) = x-7
Step-by-step explanation:
First find f(x)
f(x) is the function y =x
f(x) = x
g(x) = f(x) + C C < 0 moves it down
We want to move it down 7 units
g(x) = f(x) -7
g(x) = x-7
