How do you solve y=5/8b + 10 for b

Mathematics

joja [24]4 years ago

Answer:

b = \frac{8y-80}{5}

Step-by-step explanation:

Given

y = \frac{5}{8} b + 10

Multiply through by 8 to clear the fraction

8y = 5b + 80 ( subtract 80 from both sides )

8y - 80 = 5b ( divide both sides by 5 )

\frac{8y-80}{5} = b

What is the area of the trapezoid ?
Helga [31]

Answer:

<h2>432 ft²</h2>

Step-by-step explanation:

The formula of an area of a trapezoid is:

A=\dfrac{b_1+b_2}{2}\cdot h

<em>b₁, b₂</em><em> - bases</em>

<em>h</em><em> - height</em>

<em />

We have:

<em>b₁ = 20 ft, b₂ = 16 ft, h = 24 ft</em>

Substitute:

A=\dfrac{20+16}{2}\cdot24=\dfrac{36}{2}\cdot24=18\cdot24=432\ ft^2

Consider the diagram and the derivation below. Given: In △ABC, AD ⊥ BC Derive a formula for the area of △ABC using angle C. It i
Sedbober [7]

Answer:

A=\frac{1}{2}a*b*sin(C)

Step-by-step explanation:

First consider the diagram:

Now, we know that

Sin(C)=\frac{AD}{AC} \\ Sin(C) =\frac{h}{b} \\h=bsin(C)

Now, the area of the triangle ABC is given by,

A=\frac{1}{2}*BC*AD\\\\A=\frac{1}{2}*a*h\\\\A=\frac{1}{2}*a*c*sin(C)\\\\A=\frac{1}{2}a*b*sin(C)

Which of the lines is perpendicular to the line shown in the graph
Nitella [24]

Answer:

The line passing through (-8, 10) and (-1, 4).

Step-by-step explanation:

Two lines are perpendicular if the product of their slopes is -1. The slope of the line in the picture is 7\over 6, so we should find a line with slope of -6\over 7.

Note that the slope of the line in the last option is -7\over 6.
