Solve a = d+c ÷b for d

inna [77]

<em>Assuming the question is:</em>

$a=d+\frac{c}{b}$

we need to solve for d.

We keep "d" to one side and simplify the other side for a formula for d. Shown below:

$\begin{gathered} a=d+\frac{c}{b} \\ d=a-\frac{c}{b} \\ d=\frac{ab-c}{b} \end{gathered}$

The base of a pyramid is a square with dimensions 12 in by 12 in. The height of the pyramid is 10 in. What is the slant height o

zmey [24]

The slant height is the hypotenuse of the right triangle formed by the height and half the base length. Use the Pythagorean Theorem.

a² + b² = c²

6² + 10² = c²

36 + 100 = c²

136 = c²

√136 = √c²

c = 11.66 in

Can you multiply exponents? Please help

Greeley [361]

When you're multiplying exponents used to rule add powers together when multiplying like bases 52×56=? The bases of the equation stay the same and the values of the exponent get out of together and exponents together is just a shortcut to the answer

Answer:

B) 0.45

Step-by-step explanation:

The total number of students is:

4 + 5 + 4 + 6 + 10 + 8 + 2 + 1 = 40

The number of students with brown hair is 10 + 8 = 18.

So the probability is:

P = 18/40 = 0.45

Lines AB and CD are parallel. If 6 measures (3x - 33)°, and 5 measures 123°, what is the value of x?

Andrews [41]

The value of x from the figure is 30 degrees

<h3>Parallel lines</h3>

Parallel lines are lines that have the same slope and have 0 degrees as the angle between them.

The sum of angle 5 and angle 6 are supplementary. Hence;

m<5 + m<6 = 180

3x - 33 + 123 = 180

3x + 90 = 180

3x = 180 - 90

3x = 90

Divide both sides by 3

3x/3 = 90/3

x = 30

Hence the value of x from the figure is 30 degrees
