Answer: 35

180 = 64 + y + 2y - 11

105 = 3y

y = 35

What is 20% of 180 please i realy need to answer this

blagie [28]

Answer:

20 percent * 180 =

(20:100)* 180 =

(20* 180):100 =

3600:100 = 36

Now we have: 20 percent of 180 = 36

Question: What is 20 percent of 180?

Percentage solution with steps:

Step 1: Our output value is 180.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$180=100\%$.

Step 4: Similarly, $x=20\%$.

Step 5: This results in a pair of simple equations:

$180=100\%(1)$.

$x=20\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{180}{x}=\frac{100\%}{20\%}$

Step 7: Again, the reciprocal of both sides gives

Step-by-step explanation:

What are the end points of the triangle called? How are they labeled?

horrorfan [7]

For this case we have that by definition:

A triangle is defined by three lines that are called sides, or by three points called vertices.

We know that:

The vertices of a triangle are labeled with capital letters.
The sides of a triangle are written with lowercase letters.
The angles of a triangle are written similarly to the vertices.

Answer:

The end points of the triangle are called vertices.

They are labeled in capital letters.

What is the slope of a line that is perpendicular to the line whose equation is ax+by=c?

Oksi-84 [34.3K]

The perpendicular line will have a slope of b/a.

To find this, we first have to solve our equation for slope intercept form.

ax + by = c ----> subtract ax

by = -ax + c ----> divide by b

y = -a/bx + c/b.

So we know the slope of this equation to be -a/b. Since perpendicular lines have opposite and reciprocal slopes, we know we can simply flip the fraction and make it a negative to get the new slope of b/a.

The area of a square is 81m square.what is the perimeter of the square?how do you know

GuDViN [60]

Answer:

36m

Step-by-step explanation:

If the area of a square is 81 m

A=81m

but we know that A=l² so l=radA

l=9m

p=4l

finally p=4•9=36m

A new car is purchased for $43,000 and over time its value depreciates by one half every 6 years. What is the value of the car 2

forsale [732]

Answer:

$1,567.62

Step-by-step explanation:

If the car depreciates 50% every 6 years, we can do the following:

$43,000 ÷ 2(year 6) = $21,500

$21,500 ÷ 2(year 12) = $10,750

$10,750 ÷ 2(year 18) = $5,375

$5,375 ÷ 2(year 24) = $2,687.5

Now, for us to know how much it depreciates in 5 years to reach 29 years:

50% = 0.5 = 1/2 ÷ 6years = 0.0833 annually * 5years = 0.4167

$2,687.5 * 0.4167 = $1,119.88

$2,687.5 - $1,119.88 = $1,567.62 is the value of the car 29 years after!
