Answer: 3/5
Step-by-step explanation:
concept to know: the slope of perpendicular line is always opposite reciprocal
----------------------
Step 1. Find the slope of line t
(y2-y1)/(x2-x1)
=(4-9)/(10-7)
=-5/3
-------------------
Step 2. Apply the concept
Opposite reciprocal of (-5/3)=3/5
Hope this helps!! :)
Please let me know if you have any question
Using a system of equations, it is found that there are 10 baskets that hold 4 meals in the shop.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are given by:
- Variable x: Number of baskets that hold 2 meals.
- Variable y: Number of baskets that hold 4 meals.
There are 25 baskets in the shop, hence:
x + y = 25 -> x = 25 - y
They can hold a total of 70 meals, hence:
2x + 4y = 70
2(25 - y) + 4y = 70
2y = 20
y = 10
There are 10 baskets that hold 4 meals in the shop.

Substitute it in with the pythagorean theorem. you’ll end up getting 6^2 + 12^2 + 13^2. this equation isn't true though, because 6^2 + 12^2 = 36 + 144 = 180 and 13^2 = 169.
1) The error occurred when you moved the decimal place one spot to the left without changing the exponent of 10 to go along with it.
Not changing the exponent will change the entire value of the answer. By changing 10.35 to 1.035, we made our answer 10 times smaller, so in order to compensate for that, we need to make 10^10 ten times bigger by changing it to 10^11.
2) 10.35 x 10^10 gets changed to:
1.035 x 10^11
3) The strategy we used is to apply proper scientific notation to our answer. We should recognize when we drastically change the value of our original answer.
