Solve the equation 1/4p-5n=12 solve for n

Mathematics

kvasek [131]3 years ago

Solve the equation:

1 / 4p - 5n = 12 ========> n = 1 / 20p + -12 / 5

Let's solve for n:

1 / 4p - 5n = 12

Step 1: Add (-1) / 4p to both sides:

−5n + 1 / 4 p + −1 / 4 p = 12 + −1 / 4 p

-5n - 1 / 4p + 12

Step 2: Divide both sides by -5.

-5n / - 5 = - 1 / 4p + 12 / -5

n = 1 / 20p + -12 / 5

Answer: 1 / 4p - 5n = 12 ========> n = 1 / 20p + -12 / 5

Hope that helps!!!! : )

The balloon reaches a height of 7 feet at 0.1 seconds and 2.13 seconds

<h3>How to determine the time the balloon is at the height?</h3>

The equation of the function is given as

h(t)= -16t^2 + 35t + 5

The above equation is a quadratic equation

When the balloon is at a height of 7 feet, we have

h(t) = 7

So, we have the following equations

h(t)= -16t^2 + 35t + 5

h(t) = 7

Next, we plot the equations on a graph (see attachment)

The equations intersect at

t = 0.059 and t = 2.129

Approximate

t = 0.1 and 2.13

Hence, the times are 0.1 seconds and 2.13 seconds

Triangle ABC
Virty [35]

Answer:

15 cm

Step-by-step explanation:

Similar triangles are triangles which have the same shape but not the same size. This means their angle measures are equal but their side lengths are not instead they are proportional. To solve, we will set up a proportion and solve.

A proportion is two equal ratios set equal to each other. We form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). Out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

\frac{BC}{EF} =\frac{AC}{DF}.

\frac{18}{x}=\frac{12}{10}

To solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

\frac{18}{x}=\frac{12}{10}\\ 18*10 = x*12 \\ 180 = 12x \\ 15 = x
