Answer:
area: 454.2 sq.cm
perimeter: 77.7 cm
Step-by-step explanation:
to find area, find the area of all the separate shapes and add them together:
semi-circle:
radius is 12 cm
area =
= 226.2 sq.cm
separate the trapezoid into two right triangles and a rectangle.
area for triangles:
(5)(12) = 30
30 x 2 = 60 sq.cm (since there are two triangles)
area for rectangle:
12 x 14 = 168 sq.cm
area of whole shape: 226.2 + 60 + 168 = 454.2 sq.cm
for perimeter, just add the length of the exterior sides together.
we have some unknown sides, such as the semicircle and the sides of the trapezoid
we can find the hypotenuse of the triangles we used earlier to find the sides of the trapezoid with pythagorean theorem




c = 13 cm
to find the outside perimeter of the semi-circle, solve as if you were finding the circumference of a normal circle and divide it in half
= 37.7 cm
now add it all up:
14 + 13 + 13 +37.7 = 77.7
Answer: a=3.74
Step-by-step explanation:
first use 15 to solve for x and z. x=7.5 and z=12.99 or 13. Once you know x you can use that to solve for y and a. y=6.5 and x=7.5 and using pythagorean theorem you will find that a= the square root of 14 or 3.74.
Answer:
Fraction of drink that is water = = 0.875 = 87.5 %
Explanation:
400 ml of squash is made by mixing 50 ml of cordial with water.
Total volume of squash = 400 ml
Total volume of cordial = 50 ml
Total volume of water = 400 - 50 = 350 ml
Fraction of drink that is water = Volume of water/ Volume of squash
= 350/400
= 7/8
= 0.875 = 87.5 %
Answer:
The correct option is;
C. catalog marketing
Step-by-step explanation:
From the question, Organic designs company size = Small
Organic Designs business line = Chain store with many items
Organic Design objective = Reaching potential customers with direct marketing
Customer target of marketing campaign = Distant customers
Company long run objective is to build relationship with customers
Based on the above requirements, the catalog marketing technique is the most appropriate as it offers opportunity to sell a host of items on a platform with the ideology of an online store to distant customers who can then access items sold at Organic Designs stores through the catalog.
The general equation of the line is 3x−2y−4
