Harry pays $3.50 sales tax on a $70 item. What is the sales tax rate?

16 should be your answer, because 112 divided by 7 equals 16!

When you convert this improper fraction 112/7 to a whole number is just 16.

x=0    y=6

x=1     y=8

x=2    y=10

x=3    y=12

x=4    y=14

You can use the definition of sin to solve it.

sin(45 deg) = x/13

sin(45 deg) is known to be [tex]\frac{\sqrt{2}}{2}[/tex] so

[tex]x = \frac{13\sqrt{2}}{2}[/tex]

Let me know if you have questions.

As given,

Current value = [tex]1.2\times10^{7}[/tex] dollars

Twenty years ago value was = [tex]9.6\times10^{5}[/tex] dollars

suppose x times the investment has increased, so,

[tex]9.6\times10^{5}[/tex]*x=[tex]1.2\times10^{7}[/tex]

x = [tex]\frac{1.2\times10^{7}} {9.6\times10^{5}}[/tex]

this gives x = 12.5 times.

Hence, option B is the correct answer.

The answer is

[tex]\sqrt{x}[/tex]

because,

[tex]a^{x/n} = \sqrt[n]{x}[/tex]

First, you need to convert the minutes into hours, to do this you divide the minutes by 60 (the amount of minutes in an hour). Once you've gotten the value (which is 2.5), you divide that by the amount of miles drove, then you get the unit rate, or in other words      the kilometers per hour, which equals 49.6 km/h

Answer:

The length of the bee in the second image is 100 times the original.

Step-by-step explanation:

A science teacher showed an image of a carpenter bee on a wall. The image is 10 times as large as the actual bee.

Let the size of the actual bee be = x

So, the first image is = 10x

Then he showed another image of the bee that is 10 times as large as the first image.

Now as the length of the carpenter bee is not given, you can multiply the given length by 100 to get the answer.

The second image will be = [tex]10\times10x=100x[/tex]

So, the length of the bee in the second image is 100 times the original.

Smallest: 9

Largest: 30

In order to get the largest possible sum using the digits 4, 5, 6, 7, and 8, you should order the digits from largest to smallest (87654). For the smallest possible sum, you should order the digits from smallest to largest (45678).

Here's how you can arrange the digits 4, 5, 6, 7, and 8 to get the largest and smallest possible sums. If you're aiming for the largest sum, you should place the largest digit in the hundreds place, the next largest in the tens place, and so on. That means that you'd arrange the digits as 87654.

For the smallest sum, you should do exactly the opposite, placing the smallest digit in the hundreds place. That would result in 45678. Therefore, the largest possible sum of these digits is 87654 and the smallest possible sum is 45678.

The reason being is that we need to find it out of 100. So, we divide 400 by 4 and because we did that to the denominator we have to do it to the numerator so 16 divided by 4 is well 4. So we found out that is 4/100 we just divide that by 650 and we get 26.

TL;DR it’s $26

Tax is the price charged on an object. This shows that the tax on a $650 TV is $26

If the sales tax on a $400 stereo is $16, this can be written as:

$400 = $16

To get the sales tax on $650 TV, we can write;

$650 = x

x is the required tax;

Divide both expressions to have:

[tex]\frac{400}{650} =\frac{16}{x} \\400x = 16 \times 650\\400x = 10400\\x = \frac{10400}{400}\\x= \$26[/tex]

This shows that the tax on a $650 TV is $26

To find the result, you need to multiply the two binomials (the picture shows how to multiply them).

( -9 + 6i )( 3 - 2i )

= -27 + 18i + 18i - [tex]12i^{2}[/tex]

Combine like terms.

= -27 + 36i - [tex]12i^{2}[/tex]

Rearrange your solution into standard form.

We are given

equation of position

[tex]s(t)=(t)ln(3t)[/tex]

Calculation of velocity:

we can find derivative

[tex]s'(t)=1*ln(3t)+t*\frac{3}{3t}[/tex]

[tex]s'(t)=ln(3t)+1[/tex]

so, velocity is

[tex]v(t)=ln(3t)+1[/tex]

now, we can set it to 0

and then we can solve for t

[tex]v(t)=ln(3t)+1=0[/tex]

[tex]t=\frac{1}{3e}[/tex]

Calculation of acceleration:

we can find derivative again

[tex]v'(t)=\frac{3}{3t} +0[/tex]

[tex]v'(t)=\frac{1}{t} [/tex]

so, acceleration is

[tex]a(t)=\frac{1}{t} [/tex]

now, we can plug value of t

[tex]a(\frac{1}{3e})=\frac{1}{\frac{1}{3e}} [/tex]

[tex]15015=30\times 495 +165[/tex]

[tex]495=3\times 165 +0[/tex]

The last remainder before zero is the greatest common divisor.

Answer,

R = 1

Explanation,

Subtract 10 from both sides,

-3r + 10 - 10 = 15r - 8 - 10

Simplify,

-3r = 15r - 18

Subtract 15r from both sides,

-3r - 10 = 15r - 18 - 15r

Simplify,

-18r = -18

Divide both sides by -18,

-18r/-18 = -18/-18

Simplify,

R = 1

Hope this helps :-)

To solve the equation −3r+10=15r−8 for r, we first move all r terms to one side and constant terms to the other to get -18r = -18. We then divide both sides by -18 to find that r = 1.

The question is asking us to solve the equation −3r+10=15r−8 for the variable r. To do this, we first combine all terms involving r on one side of the equation and constant terms on the other side. Therefore, the equation becomes:

−3r - 15r = -8 - 10

which simplifies to:

-18r = -18.

We then divide both sides of the equation by -18 to solve for r:

r = 1.

Answer:

6.1 miles per hour

Step-by-step explanation:

That is 9 feet per second.

There are 3600 seconds in an hour.

9 x 3600 is 32400

That is 32400 feet in an hour.

32400 feet is about 6.1 miles. (rounded)

The airplanes speed is 6.1 miles per hour.

The speed of the airplane will be 6.13 miles/hour. It is obtained by the unit conversion.

Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. its si unit is m/sec.

Unit conversion;

1 ft/sec=0.681818 miles/hr

The speed in ft /sec;

v=d/t

v=18 feet/2 second

v=9 ft/sec

1 ft/sec=0.681818 miles/hr

9 ft/sec=9×0.681818 miles/hr

9 ft/sec=6.13  miles/hr

Hence, the speed of the airplane will be 6.13 miles/hour.

three times x = 3 × x = 3x

less 5 means subtract 5 from 3x, hence

3x - 5 → A

Answer:

[tex]3x-5[/tex]

Step-by-step explanation:

"five less than three times x"

The unknown number is x

Three times x means we multiply 3 with x

So the expression becomes 3x

5 less than 3x means we subtract 5 from 3x

To get the expression we use variables and operators like +,- . x or divide

So the final expression becomes
