The period of a pendulum is the time the pendulum takes to swing back and forth. The function relates the length L= 0.81t in feet of a pendulum to the time t in seconds that it takes to swing back and forth. A convention center has a pendulum that is 90 feet long. Find the period.

Answers

Answer 1

Answer: 111.11 seconds

Step-by-step explanation:

Given: The period of a pendulum is the time the pendulum takes to swing back and forth

The function relates the length [tex]L= 0.81t[/tex] in feet of a pendulum to the time t in seconds that it takes to swing back and forth.

If L= 90 feet then put this in the above function, we get

[tex]90=0.81t\\\\\Rightarrow\ t=\dfrac{90}{0.81}\\\\\Rightarrow\ t=111.1111111\approx111.11\text{ seconds}[/tex]

Hence,  the period = 111.11 seconds

A tanker truck fills the gas station's reservoir at the rate of 1212 gallons per minute. If the reservoir was empty and it is now 35 gallons full, how long has the tanker been filling the reservoir? Round your answer to the nearest tenth. Enter your answer in the box.

Answers

Answer:

2.9 minutes

Step-by-step explanation:

Given

[tex]Rate = 12 gallon/minute[/tex]

[tex]Size = 35\ gallon[/tex]

Required

Determine the time spent

The rate is a ratio of size to time

So, it can be expressed as:

[tex]Rate = \frac{Size}{Time}[/tex]

Substitute values for Rate and Size

[tex]12 = \frac{35}{Time}[/tex]

Cross Multiply

[tex]12 * Time = 35[/tex]

Solve for Time

[tex]Time = 35/12[/tex]

[tex]Time = 2.9[/tex] (approximated)

For lunch, a restaurant discounts prices on their menu by 15% and then applies a
10% sales tax to the discounted price. If Jade pays $18.70 after the discount and
sales tax are applied, what was the price of Jade's lunch on the menu?
A $17.48
B $19.35
C $19.68
D $20.00

Answers

Answer:

It would be D

Step-by-step explanation:

If you do the problem backward and apply the discount and taxes to 20$, then you get 18.70

The price of Jade's lunch on the menu will be;

⇒ $17.05

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

For lunch, a restaurant discounts prices on their menu by 15% and then applies a 10% sales tax to the discounted price.

And, Jade pays $18.70 after the discount and sales tax are applied.

Now,

Let the price of Jade's lunch on the menu = x

Since, A restaurant discounts prices on their menu by 15%.

Hence, The discounted price = x - 15x/100

And, Then applies a 10% sales tax to the discounted price.

Hence, The price = 10% of (x - 15x/100) + x

                           = 10/100 × 85x/100 + x

                           = 850x/10000 + x

                           = 17x/200 + x

                           = 217x/200

Since, Jade pays $18.70 after the discount and sales tax are applied.

Hence, We get;

⇒ 217x / 200 = 18.50

⇒ x = $17.05

Thus, The price of Jade's lunch on the menu will be;

⇒ $17.05

Answers

Answer:
x=-9
Step by step:
(3x +7)/2 = x-1
Multiply both sides by 2 to cancel out the division in left side:
3x+7 = 2x- 2
Subtract 2x from both sides:
x +7= -2
Subtract 7 from bo thy sides:
x=-9

Answer:

x = -9

Step-by-step explanation:

multiply 2 on both sides which cancels out the 2 in the fraction and then do -1 times 2 and 2 times x (which is just 2x). After doing that your equation should look like 3x + 7 = 2x - 2

Collect your like terms (the numbers with an x variable go togther and the ones with an x have to be together) and rearrange it so it looks like: 3x - 2x = -2 - 7 after you have this written subtract 3 from 2 now because they're on the same side which leaves you with x (usually we leave out the one because it doesn't make a difference) so now you're left with x = -2 - 7 for this step subract -2 from 7 which leaves you with x = -9

Steps:

3x + 7 = 2x - 2

3x - 2x = -2 -7

x = -2 - 7

x = -9
