The lengths of the two legs of a right triangle are 4 and 7. What is the length of the
hypotenuse? Express answer in Simplified Radical Form.
Answer:8.06
Step-by-step explanation:
4 x 4= 16 7 x 7 = 49
49+16=65
square root of 65 =8.06
Answer:
[tex] \sqrt{65} [/tex]
Step-by-step explanation:
To find the hypotenuese of a right angle you use the pythagreon theroem.
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
a and b are the height and base, while c is the hypotenuese. simply insert the values in the equation and find the variable.
[tex] {4}^{2} + {7}^{2} = {c}^{2} \\ 16 + 49 = {c}^{2} \\ 65 = {c}^{2} \\ \sqrt{65} = c[/tex]
The radical form answer is above, otherwise it would be a decimal.

An equation is shown below:
5(3x − 4) = 1
Which of the following correctly shows the first two steps to solve this equation? (1 point)
Group of answer choices
Step 1: 8x + 1 = 1; Step 2: 8x = 0
Step 1: 8x − 9 = 1; Step 2: 8x = 10
Step 1: 15x − 20 = 1; Step 2: 15x = 21
Step 1: 15x − 4 = 1; Step 2: 15x = 5
9514 1404 393
Answer:
(C) Step 1: 15x − 20 = 1; Step 2: 15x = 21
Step-by-step explanation:
The first step is to eliminate the parentheses, using the distributive property.
5(3x − 4) = 1
15x -20 = 1
The second step is to add 20 to both sides of the equation.
15x = 21
This pair of steps is shown in the 3rd choice.

Comment on the answers
The distributive property seems to be applied incorrectly a lot of the time. Here, you can choose the correct answer by looking at the result of properly applying the distributive property: 5(3x-4) = 15x-20. Only the correct choice has this as the first step.

Answer:
7/100 or Decimal: 0.07
Step-by-step explanation:
The product of 70 multiplied by 10 to the power of -3 is 0.07
Given that product of 70 multiplied by [tex]10^{-3}[/tex].
Scientific notation is a way to express numbers that are very large or very small in a more concise and convenient form. It is commonly used in scientific and mathematical calculations, as well as in representing values in various fields such as astronomy, physics, and chemistry.
To solve this, we can use the concept of scientific notation. When a number is expressed in scientific notation, the exponent indicates the power of 10 by which the number should be multiplied.
In this case, [tex]10^{-3}[/tex] means move the decimal point three places to the left.
Starting with 70, move the decimal point three places to the left to obtain 0.07. Therefore, the solution to 70 multiplied by [tex]10^{-3}[/tex] is 0.07.
Therefore, the product of 70 multiplied by [tex]10^{-3}[/tex] is 0.07.
