I think it would be 7.5!
the picture doesn't have a lot of info but to the looks of it the parallelogram is split into two equal triangles so if the parallelogram is 15 and you divide that by two since there are two triangles that look like the same it would be 7.5!

The triangle is half of the parallelogram, so that would be 7.5 cm 2

Describe the error in determining whether the lines are parallel, perpendicular, or neither.
Lina20 [59]

Step-by-step explanation:

The slopes of perpindicular lines must be negative reciprocals of each other -- while -4 and 4 are negative to each other, the negative recipricocal for -4 is 1/4 and -1/4 for 4.

The slopes of parallel lines must be the same, so these are not parallel.

Track A takes 20 minutes
Track B takes 15 minutes
In 1 minute track be will do a fraction of 1/20, while track B will do 1/15
Both tracks in a minute = 1/20+1/15
                                      = 35/300
Therefore the two tracks will take 300/35 minutes to fill the 200 cubic feet
That is 300/35
           = 8.57  minutes
           ≈ 9 minutes

<h3>What is an algebraic expression?</h3>

In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.).

<h3>How to solve algebraic expressions? </h3>

A General Rule for Equation Solving

B Remove parenthesis from either side of the equation and combine similar phrases to make it simpler.

C To separate the variable term on one side of the equation, use addition or subtraction.

D To find the variable, use division or multiplication.

Given:- The no: of package of large beads is 2

            The no: of the package of medium beads is 1

            The no: of the package of large buttons is 2

            The no: of the package of medium buttons is 2

Hence large packages

2(buttons)-2(beads)=0

For medium packages

2(buttons)-1(beads)=0

therefore, the no of more buttons than beads is 1 medium package

The father is 60 years old and his son is half his age. how old was the boy when his father was 4 times his age?
Colt1911 [192]
Let y= years ago when dad's age was 4 times son's age

60-y=4(30-y)
60-y=120-4y
-y+4y=120-60
3y=60
y=60/3
y= 20 years ago

Then 30-20= 10 yrs. old, the boys age when his dad was 40 years old.
