Answer:
Correct answer = 20 miles
Step-by-step explanation:
The mistake she made was that she made was that she multiplied the amount with 3 instead of dividing it.
The incorrect way -
$60 = 3 × 60 = 90 (Her multiplication is also incorrect as 3 × 60 = 180)
Corrected method -
$60 =
= 20 miles

Answer:
8 Weeks
Step-by-step explanation:
First let's collect the given data:
• <u>Class A:</u>
- Starts at 8 cm
- grows at 3.5 cm/week
• <u>Class B:</u>
- Starts at 10cm
- grows at 3.25 cm/week
Class B's plant starts out 2 cm taller and Class A's plant grows 1/4 cm faster. So, to find when these two will be at an equal height, divide 2 cm by 1/4.
2 ÷ 1/4 =
2 × 4/1 =
2 × 4 =
8
It will take 8 weeks for the plants to be at an equal height.
Answer:
A: Designing the layout.
Step-by-step explanation:
Remember this: Geometry uses shapes.
Let's use the process of elimination.
D is eliminated because it does not use shapes.
C is eliminated because it uses numbers, not shapes.
B is eliminated because it uses science, not math or shapes.
A uses shapes in order to design a structure.
The circle equation is in the format (x – h)² + (y – k)² = r², with the center being at the point (h, k) and the radius being "r".
QUESTION 11.
Equation x²+y²+10x-14y-7 =0 can be rewritten as: x²+10x+25 + y² -14y + 49 -7 - 25 - 49=0
It can be factories as (x + 5)² + (y – 7)² = 9²
Therefore the radius equals 9 and the center is (-5,7)
QUESTION 12.
From equation (x + 4)² + y² = 121
The radius equals √121 = 11 and the center is (-4,0)
QUESTION 13.
As there are missing information in the question, I can't assist. However, you can use the general circle equation (x – h)² + (y – k)² = r² to solve the question.
Finally equations 14 & 15 aren't linear.
Hope that helps you :)
