Jack is learning how to save,spend,and give his money away. He has determined to give away 10% if his summer job earnings. If he

romanna [79]

Answer:

Jack earned $2560 this summer.

Step-by-step explanation:

Given:

Money given away = $256

Percentile of money give away = 10%

We need to find the total money he earned this summer.

Solution:

Let the total money he earned this summer be 'x'.

So we can say that;

Money given away is equal to Percentile of money give away multiplied by total money he earned this summer and then divided by 100.

framing in equation form we get;

$\frac{10}{100}\times x = 256\\\\\frac{x}{10}=256$

Now multiplying both side by 10 we get;

$\frac{x}{10}\times 10=256\times 10\\\\x=\$2560$

Hence Jack earned $2560 this summer.

A triangle has sides with length of 12 miles 16 miles 20 miles Is it a right triangle

svetlana [45]

Answer:

Yes! This is a right triangle.

Step-by-step explanation:

To solve this problem, you need to use the Pythagorean Theorem, which is: $a^2+b^2=c^2$ . In this equation, "A" represents the smallest length, "B" represents the next smallest length, and "C" represents the largest length. If a triangle is a right triangle, then the A squared + B squared equals C squared.

In this equation:

A = 12

B = 16

C = 20

1. Insert the values: $12^2+16^2=20^2$

2. Simplify: $144+256=400$

$144+256=400$ , and $20^2=400$ , so this is a right triangle.

Hope this helps! Please feel free to give Brainliest if you feel this helped. :)
