Answer:
Step-by-step explanation:
He earned $15.20. Just multiply the 2.00x4 and the 2.40x3
To decrease an amount by 7% what single multiplier would you use. You want 7% less than 100%, so the answer is (100%-7%)=93% =0.93. Hope I helped!
Answer:
No, it is not a right triangle.
Step-by-step explanation:
If the triangle was a right triangle, then the Pythagorean Theorem states that a^2 + b^2 = c^2. Let's test it on this triangle:
13^2 + 14^2 = 365, or c^2. If this is a right triangle, c should equal 15.
However, sqrt(365) = 19.1, which is not 15. So, the triangle is not a right triangle.
Using proportions, the amounts received by each student are given as follows:
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
The amounts that each receive are given as follows:
- Ahmed: 6/7 of Ali, hence 6x/7.
- Amir: 1/7 of Ali, hence x/7.
The total amount shared is of Rs 1,400,000, hence we can solve for x as follows:
x + 6x/7 + x/7 = 1,400,000.
2x = 1,400,000.
x = 700,000.
Hence the amounts are:
