Answer:

To find the area of this right triangle, Diego and Jada used different strategies. Diego drew a line through the midpoints of the two longer sides, which decomposes the triangle into a trapezoid and a smaller triangle. He then rearranged the two shapes into a parallelogram.

0.7n - 1.5 + 7.3n = 14.5

Answer:

n = 6.5

0.7n - 1.5 + 7.3n = 14.5

0.7n+7.3n=8n

8n-1.5=14.5

Two numbers are in the ratio 7:8. Find the numbers if their sum is 45.
Galina-37 [17]
Let us assume the common ratio to be = x
Then
7x + 8x = 45
15x = 45
x = 45/15
  = 3
Then the two numbers are
7x :8x
7 * 3:8 * 3
21: 24
Then the two numbers are 21 and 24. I hope the procedure in which the problem is done is clear to you. This is a simple but effective way of solving such problems. In future this method will make you confident about solving these kind of problems.

Can someone help me with these questions please
il63 [147K]

Answer:

Please see the attached pictures for full solution.

For the first question, the inequality sign is \geqslant

because of the word "at least". This means that the profit can be greater or equal to $980.

2nd question part b: I saw your working on another post... you're almost there! After finding the circumference of the semi circle, add the diameter of the semicircle (2 radius) since it's part of the garden too.

For the 3rd question part b, I multiply 12.8 by 15 because we know that from part a that 1cm of the scale drawing represents 15 feet of the actual parking lot. Since the length of the parking lot on the scale drawing is given to be 12.8cm, the actual length is 12.8×15= 192 feet. (I answered this question on another post of yours but I decided to explain it again here)

If you have any questions, feel free to ask! :)
