75,575 how do the values of the digit differ in the number?

Vsevolod [243]

Answer:

75,575 - ten-thousands place; this 7 is worth 70,000

75,575 - thousands place; this 5 is worth 5,000

75,575 - hundreds place; this 5 is worth 500

75,575 - tens place; this 7 is worth 70

75,575 - ones place; this 5 is worth 5

A plumber has a 2.5 metre long copper pipe

Anastaziya [24]

We have an object measured in Meters, and we want to cut sections of it off in Centimeters, a different unit of measurement.

Because we're subtracting sections of the pipe, we want to make the units the same, this will make our calculations easier.

1 Meter = 100 Centimeters, so, 2.5 Meters = 250 Centimeters

We're cutting ( 60 Cm + 35 Cm + 90 Cm ) off, which totals 185 Cm.

250 Cm Pipe - 185 Cm Cuts = 65 Cm Pipe Left

Brett is joining a new gym. He can join Power Plus or Heavy Hulk. At Power Plus, it will cost $34.14 per month, plus a sign-up f

Reil [10]

After 19 months, the cost will be same for both memberships.

Step-by-step explanation:

Given,

Sign up fee at Power Plus = $22.00

Per month fee = $34.14

Let,

x be the number of months.

P(x) = 34.14x + 22

Sign up fee at Heavy Hulk = $34.50

As they have cut the cost into half.

Sign up fee = $\frac{34.50}{2}=\$17.25$

Per month fee = $34.39

H(x) = 34.39 + 17.25

For same cost ;

P(x) = H(x)

$34.14x+22=34.39x+17.25\\22-17.25=34.39x-34.14x\\4.75= 0.25x\\0.25x=4.75\\$

Dividing both sides by 0.25

$\frac{0.25x}{0.25x}=\frac{4.75}{0.25}\\x=19$

After 19 months, the cost will be same for both memberships.

Cos(theta) = - 3/4 and is in the 3rd quadrant, find the following:

elena-14-01-66 [18.8K]

Answer:

$\begin{gathered} sin(\theta)=\frac{-\sqrt{7}}{4} \\ cos(\theta)=-\frac{3}{4} \\ tan(\theta)=\frac{\sqrt{7}}{3} \\ csc(\theta)=-\frac{4}{\sqrt{7}} \\ sec(\theta)=-\frac{4}{3} \\ cot(\theta)=\frac{3}{\sqrt{7}} \end{gathered}$

Step-by-step explanation:

If theta is in the third quadrant, draw the diagram to easily identify the other trigonometric relations:

Solve for the missing leg of the triangle, using the Pythagorean theorem:

$\begin{gathered} \text{ adjacent}^2+\text{ opposite}^2=\text{ hypotenuse}^2 \\ -3^2+\text{ opposite}^2=4^2 \\ \text{ opposite=}\sqrt{16-9} \\ \text{ opposite=}\sqrt{7} \end{gathered}$

Therefore, for the trigonometric relationships:

$\begin{gathered} \text{ sin\lparen}\theta)=\frac{opposite}{hypotenuse} \\ \text{ cos\lparen}\theta)=\frac{adjacent}{hypotenuse} \\ tan(\theta)=\frac{opposite}{adjacent} \\ csc(\theta)=\frac{hypotenuse}{opposite} \\ sec(\theta)=\frac{hypotenuse}{adjacent} \\ cot(\theta)=\frac{adjacent}{opposite} \end{gathered}$

Now, substitute and solve for the relations:

$\begin{gathered} sin(\theta)=\frac{-\sqrt{7}}{4} \\ cos(\theta)=-\frac{3}{4} \\ tan(\theta)=\frac{\sqrt{7}}{3} \\ csc(\theta)=-\frac{4}{\sqrt{7}} \\ sec(\theta)=-\frac{4}{3} \\ cot(\theta)=\frac{3}{\sqrt{7}} \end{gathered}$
