A triangular pane of glass has a height of 42 inches and an area of 546 square inches. What is the length of the base of the pane?

Answers

Answer:

Base = 26 in

Step-by-step explanation:

Recall the formula for the area of a triangle as:

Area = (Base x Height) / 2

In our case, this formula converts into:

546 in^2 = Base x 42 in /2

multiply both sides by 2 to get rid of fractions:

1092 in^2 = Base x 42 in

divide both sides by "42 in" to isolate the Base completely

1092 in^2 / 42 in = Base

Therefore Base = 26 in

What is an equation of the line that passes through the point (7,-7) and is perpendicular to the line x-2y=2x−2y=2?

Answers

Answer:

y=−2x+7

Step-by-step explanation:

The other moron doesn't understand simple math.

An equation of the line that passes through the point (7,-7) and is perpendicular to the line x - 2y = 2 will be  2x + y = 0.

What is Slope of Line ?

We have the given line x - 2y = 2 which is in form ax + by = c As we know that slope of line ax + by = c will be -(a/b).

Therefore For given line x -2y = 2 value of a will be 1 and value of b will be -2. Therefor Slope of given line will be -(a/b) = -(1/-2) = 1/2.

Now As we know that slope of two lines which are perpendicular to each other has product of there slopes as negative of unity that is -1.

Let the slope of line which we have to find be m also we have slope of given line as 1/2.

∴ m(1/2) = -1

∴ (m/2) = -1

∴ m = -1(2)

∴ m = -2.

Now as we know that line passes through the point given as (7,-7) and has slope m = -2.

Therefore equation of a line passing through a point (x₁, y₁) and have slope m will be given as

  y - y₁ = m(x - x₁)

∴ y - (-7) = -2(x - 7)

∴ y + 7 = -2x -(-7)

∴ 2x + y = 7 - 7

∴ 2x + y = 0

what is 12.5% of 40?​

Answers

Answer:

5

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

Solution for What is 12.5 percent of 40:

12.5 percent *40 =

(12.5:100)*40 =

(12.5*40):100 =

500:100 = 5

Now we have: 12.5 percent of 40 = 5

Question: What is 12.5 percent of 40?

Percentage solution with steps:

Step 1: Our output value is 40.

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

Step 3: From step 1 above,$40=100\%$.

Step 4: Similarly, $x=12.5\%$.

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

$40=100\%(1)$.

$x=12.5\%(2)$.

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

$\frac{40}{x}=\frac{100\%}{12.5\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{40}=\frac{12.5}{100}$

$\Rightarrow x=5$

Therefore, $12.5\%$ of $40$ is $5$
