Step-by-step explanation:
15/3 = 5
z^-5 gets moved to the top, and made positive z^5
x^-3 gets moved to the bottom, and made positive x^3
z^5 + z^5 = z^10
x^7 + x^3 = x^10

The length of an alligator is 12.8 feet. The length of a replica toy alligator is 3 2/5 inches what scale was used?
Answer:
128 : 1
Step-by-step explanation:
Given that:
The length of an alligator = 12.8 feet.
The length of its replica toy = 3 2/5 inches = 1.2 inches
Since;
1 foot = 12 inches
Then the scale used is:
(12.8 × 12 ) inches = 1.2 inches
153.6 inches = 1.2 inches
Thus, the scale used is 128 : 1

Lindsey earns 5% commission off all sales in the clothing boutique she works at. If a customer bought $124.50 in merchandise, how much commission did she earn?
I NEED THIS ASAP
Answer:
Lindsey earned a commission of $6.23
Step-by-step explanation:
Given that:
Commission rate = 5%
Amount of merchandise bought by customer = $124.50
Commission amount = 5% of 124.50
Commission amount = [tex]\frac{5}{100}*124.50[/tex]
Commission amount = 0.05 * 124.50
Commission amount = $6.225
Rounding off to nearest cent
Commission amount = $6.23
Hence,
Lindsey earned a commission of $6.23

Each pair of polygons is similar. Find the value of x.
Answer:
The value of x is 1.5
Step-by-step explanation:
In similar figures, corresponding sides have the same ratio
In the given figure
∵ There are 2 similar polygons
∴ We must write their names with corresponding angles
∵ ∠A = ∠L, ∠B = ∠M, ∠C = ∠N, ∠D = ∠P
∴ Their names are ABCD and LMNP
→ By using the rule above
∴ Their corresponding sides have the same ratio
∴ [tex]\frac{AB}{LM}[/tex] = [tex]\frac{BC}{MN}[/tex]
∵ AB = 14 and LM = x + 9
∵ BC = 10 and MN = x + 6
→ Substitute them in the ratio up
∴ [tex]\frac{14}{x+9}[/tex] = [tex]\frac{10}{x+6}[/tex]
→ By using the cross multiplication
∵ 14 × (x + 6) = 10 × (x + 9)
∴ 14(x) + 14(6) = 10(x) + 10(9)
∴ 14x + 84 = 10x + 90
→ Subtract 10x from both sides
∵ 14x - 10x + 84 = 10x - 10x + 90
∴ 4x + 84 = 90
→ Subtract both sides by 84
∵ 4x + 84 - 84 = 90 - 84
∴ 4x = 6
→ Divide both sides by 4 to find x
∴ x = 1.5
∴ The value of x is 1.5
A bike cost 8$ plus 3$ Per hour. Ravi spent 29$ for a bike rental. For how many hour did Ravi rent the bike
Answer: 7 hours
Step-by-step explanation:
Let the number of hours used be represented by h.
Since a bike cost 8$ plus 3$ Per hour and Ravi spent 29$ for a bike rental.
This can be represented in an equation as:
8 + 3h = 29
Collect like terms
3h = 29 - 8
3h = 21
h = 21/3
h = 7 hours
Ravi rented the bike for 7 hours

. SHOPPING Mrs. Williams shops at a store that has an annual membership fee of $30. Today she paid her annual membership and bought several fruit baskets costing $15 each as gifts for her coworkers. Her total was $105. Solve the equation 15b + 30 = 105 to find the number of fruit baskets Mrs. Williams purchased.
Answer: Mrs. Williams purchased 5 fruit baskets.
Step-by-step explanation:
Here , b= number of fruit baskets
Given equation: 15b + 30 = 105
Subtract 30 from both sides
15b = 105-30
⇒ 15b = 75
Divide both sides by 15 , we get
b= 5
Hence, Mrs. Williams purchased 5 fruit baskets.
A circle with a diameter 28m. Find it area and circumference Take[Π=3.4]
Diameter of a circle = 28 m
Then, radius of the circle will be :
[tex] = \tt \frac{diameter}{2} [/tex]
[tex] =\tt \frac{28}{2} [/tex]
[tex] = \tt14 \: m[/tex]
Thus, the radius of this circle = 14 m
Area of circle :
[tex] = \tt\pi {} {r}^{2} [/tex]
[tex] =\tt 3.14 \times 14 \times 14[/tex]
[tex] = \tt3.14 \times 196[/tex]
[tex] = \tt615.44 \: {m}^{2} [/tex]
Thus, the area of this circle = 615.44 m²
Circumference of circle :
[tex] = \tt2\pi r[/tex]
[tex] =\tt 2 \times 3.14 \times 14[/tex]
[tex] = \tt87.92 \: m[/tex]
The circumference of this circle = 87.92 m
Therefore, the area of this circle = 615.44m² and the circumference of this circle = 87.92m
Y=2x + 4 y= -10/3 x + 76/3 what is the sum of the x- and y-values in the solution to the system of equations?
Given:
The system of equations:
[tex]y=2x+4[/tex]
[tex]y=-\dfrac{10}{3}x+\dfrac{76}{3}[/tex]
To find:
The sum of the x- and y-values in the solution to the system of equations.
Solution:
We have,
[tex]y=2x+4[/tex] ...(i)
[tex]y=-\dfrac{10}{3}x+\dfrac{76}{3}[/tex] ...(ii)
From (i) and (ii), we get
[tex]2x+4=-\dfrac{10}{3}x+\dfrac{76}{3}[/tex]
[tex]2x+\dfrac{10}{3}x=\dfrac{76}{3}-4[/tex]
[tex]\dfrac{6x+10x}{3}=\dfrac{76-12}{3}[/tex]
Multiply both sides by 3.
[tex]16x=64[/tex]
Divide both sides by 16.
[tex]x=\dfrac{64}{16}[/tex]
[tex]x=4[/tex]
Putting x=4 in (i), we get
[tex]y=2(4)+4[/tex]
[tex]y=8+4[/tex]
[tex]y=12[/tex]
The solution of system of equations is (4,12).
[tex]x+y=4+12[/tex]
[tex]x+y=16[/tex]
Therefore, the sum of the x- and y-values in the solution to the system of equations is 16.

The length of the diagonal of the screen is 19.2 inches
What is the diagonal of a rectangle?
The diagonal of a rectangle is calculated by the formula
From the Pythagoras Theorem , The hypotenuse² = base² + height² , and
Diagonal of a Rectangle = √ ( Length )² + ( Width )²
Given data ,
The length of the screen of the monitor is L = 15 inches
The width of the screen of the monitor is W = 12 inches
Now ,
The diagonal of the screen of the monitor is calculated by ,
Diagonal of a Rectangle = √ ( Length )² + ( Width )²
So ,
Substituting the value of length L and width W , we get
Diagonal of the screen = √ ( 15 )² + ( 12 )²
= √ ( 225 ) + ( 144 )
= √ 369
≈ 19.209 inches
Therefore , the diagonal of the screen is 19.209 inches
Hence , The length of the diagonal of the screen is 19.2 inches

When f(x) = 0.5|x is graphed on a regular coordinate grid, the graph forms
Answer:
A. Right angle -- if you multiply the slopes of 2 intersecting lines and you "-1" then the lines are perpendicular - in this case the line in quadrant 3 has a slope of "1" and the line in quadrant 4 has a slope of "-1", hence their product is "-1" and the angles formed at the intersection of the lines are right angles.

Is there a proportional relationship? A salt water solution for and aquarium calls for 35 parts of salt to 1000 parts of water tareq used a ratio of 7 parts of salt and 200 parts of water
Answer:
Yes
Step-by-step explanation:
To check proportionality :
35 α 1000
35 = 1000k
k = constant of proportionality ;
Divide both sides by 1000 to obtain k
35 / 1000 = 1000k / 1000
0.035 = k
For the ratio Given :
Ratio of 7 parts of salt and 200 parts of water
7 : 200
7 / 200
= 0.035
Since,
k = 0.035 ; 7 / 200 = 0.035
Hence, a proportional relationship exists.

a.f(n)=n^2+2
b.f(n)=2n^2+1
c.f(n)=2n+1
d.f(n)=3n^2
Answer:
b. f(n) = 2n^2 + 1
Step-by-step explanation:
Thanks for explaining the nth thing to me. It all makes sense now :'D
I'll be honest I think you're at least a grade level above me in math.
It's b. because
f(n) = 2(1)^2 + 1
2(1) + 1
2 + 1 = 3 (first term)
f(n) = 2(2)^2 + 1
2(4) + 1
8 + 1 = 9 (second term) ...and so on. :)
