Answer:
Step-by-step explanation:
a. 5/2 ÷ 1/2 =
b. 6/9 ÷ 5/6
c. 3/6 ÷ 2/5
d. 7 1/2 ÷ 6
=
e. 1 1/3 ÷ 1 2/3=
- 4/3 ÷ 5/3 =
- 4/3 * 3/5 =
- 4/5
Because the area in the drawing is 36 cm^2, one side length is 6 cm.
On the actual floor, this equates to 24 ft.
This means the area of the floor in real life is 576 square feet.
Therefore the ratio is 36 square centimetres : 576 square feet.
This is the same as 1 square centimetre : 16 square feet.
Answer:
32
Step-by-step explanation:
ratio of areas equal the ratio of corresponding sides squared (*)
ratio of corresponding sides of triangle ABC and triangle ADE = 4/1
area of triangle ADE will equal x, so then the area of triangle ABC will be x + 30 (bc the area of ADEC is 30, you just add that to x to get the area of ABC)
now let's set up our proportion:
Area of triangle ABC 4^2
--------------------------------- = ---------- <---- 4/1 is squared because of (*)
Area of triangle ADE 1^2
substitute:
A + 30 16
---------- = ----------
A 1
cross multiple to get A = 2, so then ABC = ADE + ADEC, which is 30 + 2 = 32
i did draw a diagram but after reviewing i drew it wrong so good luck drawing the diagram
also is this your 8th grade honors geometry math hw for RSM? HW 23 or something. if yes then oof.
comment if u have questions
