Find two consecutive odd integers whose sum is 72

Answers

Answer 1
Answer:


Here is how you would do it:

x + (x+2) = 72     ----->     x is your first integer, and x+2 is your second integer. It isn't x+1 because that would mean that you're adding an odd and an even integer. So you would have to add 2 to your first integer to get two consecutive integers. Let's continue:

2x + 2 = 72

2x = 70

x = 35     ----->    So, 35 would be your first integer and 37 (which came from 35 + 2) would be your next consecutive integer.

Two sides of a right triangle are 8” and 12”.A. Find the the area of the triangle if 8 and 12 are legs.

B. Find the area of the triangle if 8 and 12 are a leg and hypotenuse.

Answers

Area of a right triangle = ab/2

where a and b are both legs of the triangle.

A) a = 8 inches ; b = 12 inches
A = (8in x 12in)/2 = 96/2 = 48 in²

B.) a = 8 inches ; b = ? ; hypotenuse = 12 inches

Pythagorean theorem is used to get the measurement of the hypotenuse. It can also be used to get the measurement of the missing leg.

a² + b² = c² ⇒ b² = c² - a²
b² = 12² - 8²
b² = 144 - 64
b² = 80
b = √80
b = 8.94

A = ab/2 ⇒ (8 inches * 8.94 inches)/2
A = 71.52 in² / 2
A = 35.76 in²

Solve for each expression by writing the solution in unit form and in standard form 6 ten thousands divided by 10

Answers

Solve the given equation by writing the solution inUnit form and Standard form.
Given equation = 6 ten thousands divided by 10

Unit form – place Value form
=> 6 ten thousands
=> divided = /
=10 or 1 tens
=> 6 ten thousands / 1 tens
=> 6 thousands

Standard form- Numerical form
=> 6 ten thousands = 60 000
=> divided = /
=> 10
=> 60 000 / 10
=> 6000

Thus, the answer of 6 ten thousands divided by 10 is equals to 6000
