Answer:
A=q-n
Step-by-step explanation:
To get A by itself you have to subtract n from both sides of the equation
A+n=q
-n=-n
A=q-n

A Wonsan has 30 coins in her pocket, all of which are dimes and quarters . If the total value of the coins is $4.50 ,how many dimes and how many quarters does she have ?
Answer:
The number of
Dimes = d = 20 dimes
Quarters = q = 10 quarters
Step-by-step explanation:
Let us represent
The number of :
Dimes = d
Quarters = q
Note that:
A dime is worth 10 cents = 0.10d
A quarter is worth 25 cents = 0.25q
A Wonsan has 30 coins in her pocket, all of which are dimes and quarters .
d + q = 30...... Equation 1
d = 30 - q
If the total value of the coins is $4.50
0.10d + 0.25 q = 4.50.....Equation 2
We substitute 30 - q for d in Equation 2
0.10(30 - q) + 0.25q = 4.50
3 - 0.10q + 0.25q = 4.50
- 0.10q + 0.25q = 4.50 - 3
0.15q = 1.5
q = 1.5/0.15
q = 10 quarters
Solving for d
d = 30 - q
d = 30 - 10
d = 20 dimes
Therefore:
The number of
Dimes = d = 20 dimes
Quarters = q = 10 quarters

Sissy wants to enlarge a picture of a constellation so that she can put it on the wall in her daughter’s room. What will be the area of the enlarged picture on the wall?
24 in.2
108 in.2
224 in.2
486 in.2
Answer: 486 in
Just did this on edge
The enlargement transformation applied to the rectangular figure gives
a rectangle that is enlarged and similar to the figure.
Correct response:
The area of the enlarged picture is 486 in.²The given dimensions of the picture are;
Height, [tex]\overline{MN}[/tex] = 6 in.
Width, [tex]\overline{LP}[/tex] = 4 in.
The length of QL' = 12 + 42 = 54
By similar triangles, we have;
[tex]\dfrac{\overline{L'P'}}{\overline{LP}} = \mathbf{ \dfrac{\overline{QL'}}{\overline{QL}}}[/tex]
Which gives;
[tex]\dfrac{\overline{L'P'}}{6} = \mathbf{ \dfrac{54}{12}}[/tex]
[tex]\overline{L'P'} = \dfrac{54 }{12} \times 6 = \mathbf{27}[/tex]
Given that an enlargement gives similar figures, we have;
[tex]\dfrac{\overline{L'P'}}{\overline{LP}} = \mathbf{\dfrac{\overline{L'M'}}{\overline{LM}}} = Scale \, factor \ of \ the \ enlargement[/tex]
Therefore;
[tex]\dfrac{27}{6} = \dfrac{\overline{L'M'}}{4}[/tex]
Which gives;
[tex]\overline{L'M'} = \dfrac{27}{6} \times 4 = \mathbf{ 18}[/tex]
The area of the enlarged picture is, A = [tex]\overline{L'M'}[/tex] × [tex]\overline{L'P'}[/tex]
Which gives;
A = 27 × 18 = 486
The area of the enlarged picture on the wall is A = 486 in.²

Answer: 69.12
Step-by-step explanation: circumference=2*pi*radius
Answer:
The circumference of the circle is 69.12 m
Step-by-step explanation:
Circumference of a Circle
Given a circle of radius r, the circumference or perimeter of the circle is calculated by the formula:
[tex]C=2\pi\ r[/tex]
The circle shown in the image has a radius of r=11 m, thus the circumference is:

Answer:
Simplified form of [tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex] is [tex]\mathbf{\frac{1}{(x+3)(x+4)} }[/tex]
Option A is correct answer.
Step-by-step explanation:
We need to find simplified form of [tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex]
Solving the given expression:
[tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex]
First we find factors of [tex]x^2+x-6[/tex]
[tex]x^2+x-6 \\= x^2+3x-2x-6\\= x(x+3)-2(x+3)\\=(x-2)(x+3)[/tex]
So, factors of [tex]x^2+x-6[/tex] are [tex](x-2)(x+3)[/tex]
Now, fining the factors of [tex]x^2+5x+4[/tex]
[tex]x^2+5x+4\\=x^2+4x+x+4\\=x(x+4)+1(x+4)\\=(x+1)(x+4)[/tex]
So, factors of [tex]x^2+5x+4[/tex] are [tex](x+1)(x+4)\\[/tex]
Now the given expression will become:
[tex]\frac{x+1}{(x-2)(x+3)}\div \frac{(x+1)(x+4)}{x-2}[/tex]
Now, converting division sign into multiplication sign:
[tex]=\frac{x+1}{(x-2)(x+3)}\times \frac{x-2} {(x+1)(x+4)}\\Cancelling, \:common\:terms\\=\frac{1}{(x+3)(x+4)}[/tex]
So, simplified form of [tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex] is [tex]\mathbf{\frac{1}{(x+3)(x+4)} }[/tex]

A water tank holds 522 gallons but is leaking at a rate of 4 gallons per week. A second
water tank holds 696 gallons but is leaking at a rate of 7 gallons per week. After how many
weeks will the amount of water in the two tanks be the same?
The amount of water in the two tanks will be the same in
weeks.
Answer:
58 weeks
Step-by-step explanation:
Water tank A = 522 - 4x
Water tank B = 696 - 7x
Where,
x = number of weeks
Equate both equations
522 - 4x = 696 - 7x
Collect like terms
522 - 696 = -7x + 4x
-174 = -3x
Divide both sides by - 3
x = -174/-3
x = 58 weeks
The amount of water in the two tanks will be the same in 58
weeks
The area of a circular mouse pad is 64 square inches. Use 3.14 for 7. Estimate its radius to the nearest integer.
Answer:
about 4.52
Step-by-step explanation:
Since pi times radius squared is the formula for area, you would first divide 64 by 3.14 to get about 20.4. Then since you square the radius, you would do the opposite and find the square root which is about 4.52.

determine a similarity transformation that maps the primage to the image.
Answer:
Step-by-step explanation:
From the figure attached,
ΔABC has been dilated to form another triangle ΔA'B'C'.
Therefore, ΔA'B'C' is the image triangle of preimage ΔABC.
Coordinates of preimage ΔABC are,
A(3, 3), B(2, 0) and C(5, 2)
Coordinates of ΔA'B'C',
A'(6, 6), B'(0, 4) and C'(10, 4)
Since, dilation of a triangle is a similarity transformation which produces the similar image of the preimage.
Rule for the dilation is,
(x, y) → (kx, ky)
Here, k = scale factor of dilation
By this rule,
A(3, 3) → A'(6, 6)
→ A'(2×3, 2×3)
Scale factor = 2
Therefore, "Triangle (ABC) is dilated by a scale factor 2 about the origin to form triangle (A'B'C') ".
