Answer:
33 ft
Step-by-step explanation:
The perimeter formula for a rectangle is ...
P = 2(L +W)
Filling in the given numbers, we have ...
146 = 2(40 +W)
73 = 40 +W . . . . . . . divide by 2
33 = W . . . . . . . . . . . subtract 40

Jeans are on sale for 25% off. The jeans Bailee wants to buy are marked with an original price of $60. What is the total cost, in dollars, for a pair of jeans at the sale price, including a 7% tax?
The total cost for a pair of jeans at the sale price including 7% tax is $96.30.
What is Percentage?Percentage, denoted by %, is defined as the parts of a number per fraction of 100.
We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
here, we have,
Given that,
Original price of the jeans = $60
Discount percentage = 25%
Amount of discount = 25% × 60
= 0.25 × 60
= $15
Price of a jean at the sales price = $60 - $15 = $45
Percentage tax = 7%
Tax amount = 7% × 45 = 0.07 × 45 = $3.15
Price of the jean after tax = $45 + $3.15 = $48.15
Total cost for a pair of jeans = 2 × $48.15 = $96.30
Hence the total cost is $96.30.

Find the measure of
Answer:
m∡GHI = 21°
Step-by-step explanation:
Since the lines are intersecting, GHI and JHK are opposite angles, so they are the same measure.
That means you can set them equal to each other
x + 7 = 3x - 21
x = 14
Now plug x into GHI
14 + 7 = 21
m∡GHI = 21°

Is it possible to form a triangle with side lengths 3.5 3.5, and 9? If so, will it be scalene, isosceles, or equilateral? Or none
Answer:
It is not possible to draw a triangle with given measurements of 3.5, 3.5, and 9.
Step-by-step explanation:
Scalene Triangle - All 3 sides have different lengths.
Isosceles Triangle - 2 sides have equal lengths.
Equilateral Triangle - All 3 sides have equal lengths.
You must be thinking that it would be Isosceles triangle, but it is not. The measurements you gave is 3.5, 3.5, and 9. Grab a piece of paper, ruler, and a pencil. First draw the length of 9 cm with your pencil and ruler (let us pretend that the measurements are in cm). Then draw 3.5 cm by placing your ruler on the end/start of your 9cm line that you drew before. Then, once again draw a 3.5 cm on the other end of the 9cm line. You will see something like the picture above. You can see that the two sides of the triangle are not intersecting on the top. This means that the triangle formation cannot be made by the given measurements of 3.5, 3.5, and 9.
I hope you understand my answer and this is an easy way to find if, from the given measurements, a triangle is able to be drawn. Thank you !!
The given side lengths, 3.5 3.5, and 9, cannot form a triangle.
The Triangle Inequality TheoremThe triangle inequality theorem states that for any triangle, the sum of any two of its side must be greater than the length of the third side.Given the side lengths, 3.5 3.5, and 9:
3.5 + 3.5 (7) is not greater than 9
Thus, we can conclude that the given side lengths, 3.5 3.5, and 9, cannot form a triangle.

How do you solve for x and y?
Answer:
x = 60°, y = 30°
Step-by-step explanation:
The sum of the triangle angles is always 180°
Therefore 90° + x + y = 180°
It is also known that x = 2y
// combine the given value of x into the previous expression
90° + 2y + y = 180°
2y + y = 180° - 90°
3y = 90°
// divide both sides by 3
y = 30°
// then combine the given value of y into the expression x = 2y
x = 2 * 30°
x = 60°

What is the value of the expression below?
1 3/4 divided by 1/2 minus (1 1/2)^3
Answer:
1/8
Step-by-step explanation:
Simplify the following:
(1 + 3/4)/(1/2) - (1/2 + 1)^3
Hint: | Write (1 + 3/4)/(1/2) as a single fraction.
Multiply the numerator of (1 + 3/4)/(1/2) by the reciprocal of the denominator. (1 + 3/4)/(1/2) = ((1 + 3/4)×2)/1:
(3/4 + 1) 2 - (1/2 + 1)^3
Hint: | Put the fractions in 1 + 1/2 over a common denominator.
Put 1 + 1/2 over the common denominator 2. 1 + 1/2 = 2/2 + 1/2:
(1 + 3/4) 2 - (2/2 + 1/2)^3
Hint: | Add the fractions over a common denominator to a single fraction.
2/2 + 1/2 = (2 + 1)/2:
(1 + 3/4) 2 - ((2 + 1)/2)^3
Hint: | Evaluate 2 + 1.
2 + 1 = 3:
(1 + 3/4) 2 - (3/2)^3
Hint: | Put the fractions in 1 + 3/4 over a common denominator.
Put 1 + 3/4 over the common denominator 4. 1 + 3/4 = 4/4 + 3/4:
4/4 + 3/4 2 - (3/2)^3
Hint: | Add the fractions over a common denominator to a single fraction.
4/4 + 3/4 = (4 + 3)/4:
(4 + 3)/4×2 - (3/2)^3
Hint: | Evaluate 4 + 3.
4 + 3 = 7:
7/4×2 - (3/2)^3
Hint: | Express 7/4×2 as a single fraction.
7/4×2 = (7×2)/4:
(7×2)/4 - (3/2)^3
Hint: | In (7×2)/4, divide 4 in the denominator by 2 in the numerator.
2/4 = 2/(2×2) = 1/2:
7/2 - (3/2)^3
Hint: | Simplify (3/2)^3 using the rule (p/q)^n = p^n/q^n.
(3/2)^3 = 3^3/2^3:
7/2 - 3^3/2^3
Hint: | In order to evaluate 3^3 express 3^3 as 3×3^2.
3^3 = 3×3^2:
7/2 - (3×3^2)/2^3
Hint: | In order to evaluate 2^3 express 2^3 as 2×2^2.
2^3 = 2×2^2:
7/2 - (3×3^2)/(2×2^2)
Hint: | Evaluate 2^2.
2^2 = 4:
7/2 - (3×3^2)/(2×4)
Hint: | Evaluate 3^2.
3^2 = 9:
7/2 - (3×9)/(2×4)
Hint: | Multiply 2 and 4 together.
2×4 = 8:
7/2 - (3×9)/8
Hint: | Multiply 3 and 9 together.
3×9 = 27:
7/2 - 27/8
Hint: | Put the fractions in 7/2 - 27/8 over a common denominator.
Put 7/2 - 27/8 over the common denominator 8. 7/2 - 27/8 = (4×7)/8 - 27/8:
(4×7)/8 - 27/8
Hint: | Multiply 4 and 7 together.
4×7 = 28:
28/8 - 27/8
Hint: | Subtract the fractions over a common denominator to a single fraction.
28/8 - 27/8 = (28 - 27)/8:
(28 - 27)/8
Hint: | Subtract 27 from 28.
| 2 | 8
- | 2 | 7
| 0 | 1:

Answer:
y = 240,000(1.048)^t
Step-by-step explanation:
Initial population: p = 240,000
Annual growth rate: 4.8% = 0.048
Number of years: t
Population in year t: y
y = p(1 + r)^t
y = 240,000(1 + 0.048)^t
y = 240,000(1.048)^t
