The area of the lot with a shape of a parallelogram if its base measures 20 meters and the distance given is 160m².
How to calculate the area?Area of a parallelogram will be:
= Base × Height
= 20 × 8
= 160m²
The area of the triangular landscape that has a base of 24 meters and a height of 12 meters will be:
= 1/2 × base × height
= 1/2 × 24 × 12
= 144m²
The area of the trapezium will be:
= 1/2 × (a + b) × h
= 1/2 × (16 + 30) × 10
= 1/2 × 46 × 10
= 230m²
The area of the rectangular banner has a length of 5 meters and a width of 3 meters will be:
= Length × Width
= 5 × 3
= 15m²

NO LINKS!! Find the perimeter of the figure
Answer:
178
Step-by-step explanation:
Perimeter = distance all the way around the outside of a 2D shape
Missing vertical length = 45 - 14 - 17 = 14
Missing horiztonal length = 44 - 8 - 29 = 7
⇒ perimeter = 45 + 8 + 17 + 29 + (45 - 14 - 17) + (44 - 8 - 29) + 14 + 44
= 45 + 8 + 17 + 29 + 14 + 7 + 14 + 44
= 178
Answer:
First finding the perimeter of rectangle

To decide if it's feasible to do this by investing in an account that compounds annually, he needs to determine the annual interest rate such an account would have to offer for him to meet his goal. What would the annual rate of interest have to be?

given: tangent TA is parallel to KM. Prove: KS = MS
When tangent TA is parallel to KM, it can be proved that KS = MS since they're congruent.
How to prove the tangent?It should be noted that when the tangent line TA is parallel to chord KM, it simply means that segment KS and MS are congruent.
Therefore, since they're congruent, SKM and SMK are equal. By the theorem of inscribed angle, we will have:
SKM = 1/2m(MS)
SKM = 1/2m(KS).
Since SKM = SMK
1/2m(MS) = 1/2m(KS).
MS = KS

I just made a purchase of $130.00 but once I got my car and looked at the receipt, I realized the salesperson who helped me did not apply the 15% discount
Answer:
Guessing you want me to figure out what your cost should have been. On it!
Step-by-step explanation:
130 * .15 = 19.5
130 - 19.5 = $110.5
That should be the new cost.
The price of the thing after applying 15% discount is $110.50.
What is percentage?Percentage is a measurement to find value of given number out of hundred.
Given that,
The price at which thing is purchased = $130.
Since, The salesperson forgot to give a discount of 15%.
The discounted price = 130 x 15 %
= 130 x 15/100
= 1950/100
= $19.5
The price after discount = 130 - 19.5 = 110.5
The required price after discount is $110.5.

x = –3.5 or x = 4
x = 2 or x = –7
x = –2 or x = 7
x = –4 or x = 3.5
Answer:
The value of x = 3.5 or -4
Step-by-step explanation:
=> 2x² = 28 – x
=> 2x²+ x - 28 = 0
=> 2x² + 8x - 7x - 28 = 0
=> 2x ( x + 4 ) - 7 ( x + 4 ) = 0

A company collects data on its employees. It finds that
. 20% of employees in each department are part-time,
80% of employees in each department are full-time, and
• each of the company's four departments has 45 employees.
How many part-time and full-time employees does the company have?
Answer:
9 Part-time employees
36 full-time employee
Step-by-step explanation:
20% multiply by 45 = 9
80% multioly by 45 =36
therefore to check if your answers are correct add 9 + 36 which gives you 45, the total number of employees in each company's four department.
Answer:
The company has 144 full-time employees and 36 part-time employees.
Step-by-step explanation:
The company has 144 full-time employees and 36 part-time employees because you have to do .20*45 to get 9 part-time employees per department. Then you can do 45-9 to get 36 full-time employees per department or you can do .8*45, either way is fine. Then you have to multiply 36 by 4 and 9 by 4 to get 144 full-time employees and 36 part-time employees.

Answer:
136
Step-by-step explanation:
First you multiply 7•5 which is 35, and sense there is 2 squares with that unit, you multiply 35•2 which is 70. After that you get the middle value by multiplying 6•7, which is 42. Then you add 42+70, and that's 112. Now you have to find the area of the triangle, so you multiply 6•4, and that's 24, but sense there are 2 of them with the same unit you don't need to divide by 2. Then after that you add 112+24 and the total area is 136
Answer:
136 square units
Step-by-step explanation:
A "net" is a map of the surfaces of the prism. If you cut it out and fold along the solid lines, you can shape it into the triangular prism it represents. The area of the net is the area of the prism.
As with any composite figure, its area can be found by decomposing it into parts whose area formulas you know. Here, the net can be cut along the horizontal lines to form a rectangle and two triangles.
__
rectangleThe rectangle has an overall length of 5+6+5 = 16 units, and a width of 7 units. Its area is ...
A = LW
A = (16)(7) = 112 . . . . square units
trianglesEach triangle has a base of 6 units and a height of 4 units. Its area is ...
A = 1/2bh
A = 1/2(6)(4) = 12 . . . . square units
total areaThe composite figure shown has been decomposed into one rectangle and two triangles, so its total area is ...
rectangle area + 2 × triangle area
= 112 + 2×12 = 136 . . . . square units
The surface area of the triangular prism is 136 square units.

SM 4 - 7 A shoe store marks up
its merchandise by 8%. What is the
selling price of a pair of shoes
whose wholesale price was
$34.50?
Assuming $34.50 is the price after the 8% price increase, we can set up this equation (if 34.50 is the old price, scroll down):
34.50=[tex]\frac{108}{100} x[/tex]
Where x ( or 100/100 x) is the original price.
We can simply the fraction, or just multiply by 100 on both sides.
3450=108x
x=31.9444 (4 repeating).
If the old price is 34.50, then we can set up this equation:
34.50+ [tex](\frac{8}{100} *34.50)[/tex] = x
34.5 + 2.76 = x
x = 37.26
The new selling price would be $37.26.
