Evaluate. Pay close attention to all brackets and signs.|4| - |-5|
a. 9
c. 1
b. -9

Answers

|4| - |-5|
all the absolute numbers are always positive.
when you will open the brackets positive will remain positive and negative will change to positive so we get
4 - 5
= -1 Ans
The answer to this equation is 9.

David waits by the crosswalk sign on his way to school. The angle outlined on the sign turns through 50 one-degree angles. Find the measure of the angle.

Answers

Answer:

7(1)/(5)th turns

Step-by-step explanation:

An angle that turn through n one-degrees is said to have an angle measure of n degree.  An angle that turns through 1/360 of a circle is called a one degree angle, this is used to measure angles

:. measure of the angle turns through 50 one degree angles

= (360)/(50)   =  7(1)/(5)th turns.

HELP PLEASE 15 POINTS!!A student is attempting to simplify the exponent shown below. Which statement best applies to the sample mathematical work?
given (2x/y)^9* (x/3)^2
Step 1: I first apply the exponent in the left term, which gives the quantity 8x^3/y^3
Step 2: I next apply the exponent in the right term, which gives the quantity x^2/9
Step 3: I combine the two terms from Step 1 and Step 2 and simplify to get a final answer of 8x^6/9y^3

A.
The student incorrectly applies the exponent in Step 1.
B.
The student incorrectly applies the exponent in Step 2.
C.
The student incorrectly combines the results from Steps 1 and 2 in Step 3.
D.
The mathematical work shown is correct.

Answers

first step is wrong

In a right triangle, if the length of the hypotenuse is 5 and the length of one of the other sides is 3, what is the length of the third side?​

Answers

Answer:

a^2+b^2=c^2

a^2+9=25(5*5)

therefore ,a^2=25-9=16

√16=4

   sides are 4 cm,3 cm,5 cm

Step-by-step explanation:

4.

Step-by-step explanation:

Pythagoras theorem says that "In a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides". As the Hypotenuse side is already yet given and one of the side of a triangle value is given. Now we should find the value for other side of a triangle. In order to find the value of other side, we should use the Pythagoras theorem formula.

AC²=AB²+BC²

Let AC be the Hypotenuse side, AB and BC be the other two sides of a triangle.

Given:-

AC=5,AB=3,BC=?

Use Pythagoras theorem formula

AC²=AB²+BC²

5²=3²+BC²

25=9+BC²

25-9=BC²

16=BC²

√16=BC

BC=4.
