The sales tax in Bill's state is 6%. Bill bought a Scion having a sales tax of $820. What was the cost of the car, rounded to the nearest dollar.

Let us say that the procedure of completely filling up the pool with water is called “1 job”. Therefore the rates of the equipment in doing the job would be:

Rate of handheld hose = 1 job / 8 minutes                  ---> 1

Rate of lawn sprinkler = r                                             ---> 2

Rate of the two combines = 1 job/ 5 minutes               ---> 3

So we are to find the equation to use, in this case, we simply have to add equations 1 and 2 to get 3:

1 / 8 + r = 1 / 5

Multiplying both sides by 5:

(5 / 8) + 5 r = 1                                                               ---> ANSWER

Answer:

In a certain town 22% of voters favor a given ballot measure for groups of 21 voters find the variance for the number who favor the measure

a. 1.9

b. 13

c. 4.6

d. 3.6

Here is my answer:

Given:

So the variance is: 21*0.22 = 4.6

We choose B

The value of cosx if "tanx cscx = 2" is 1/2. The correct option is D)1/2

From the question, we are to determine the value of cosx

From the given information,

tanx cscx=2

Recall that,

[tex]tan(x )= \frac{sin (x)}{cos(x)}[/tex]

and

[tex]csc(x) = \frac{1}{sin(x)}[/tex]

Then,

Substitute these values into the given equation

tanx cscx = 2 becomes

[tex]\frac{sin (x)}{cos(x)} \times \frac{1}{sin(x)} = 2[/tex]

[tex]\frac{1}{cos(x)} = 2[/tex]

∴ [tex]cos(x) = \frac{1}{2}[/tex]

Hence, the value of cosx if "tanx cscx = 2" is 1/2. The correct option is D)1/2

The equation that represents the number of hours the mountaineer climbed is t = 1000/V1 + 2600(V1 - 5).

Based on the information given, V1 = 1000 and V2 = 2V1 - 10.

The time taken will be:

= 1000/V1 + 5000/V2

Well substitute the equations. This will be:

t = 1000/V1 + 5000//(2V1 - 10)

t = 1000/V1 + 5000/2(V1 - 5)

t = 1000/V1 + 2600(V1 - 5).

Final answer:

To eliminate the parameter 't' from the equations x = 5 cos t and y = 5 sin t, use the Pythagorean identity which leads to the non-parametric equation of a circle: x^2 + y^2 = 25.

Explanation:

To eliminate the parameter 't' from the parametric equations x = 5 cos t, y = 5 sin t, we can use the Pythagorean identity sin^2(t) + cos^2(t) = 1. Plugging in the given expressions for x and y:

(x/5) = cos(t)

(y/5) = sin(t)

We can square both sides of these equations and then add them together:

(x/5)^2 + (y/5)^2 = cos^2(t) + sin^2(t)

As cos^2(t) + sin^2(t) equals 1, the equation simplifies to:

(x/5)^2 + (y/5)^2 = 1

Thus, the eliminated parameter equation representing the same curve without the parameter 't' is:

x^2 + y^2 = 25

This is the equation of a circle with a radius of 5, centered at the origin.

To find the volume of the solid enclosed by the given cylinder and planes, you convert to cylindrical coordinates. Then, you set up a triple integral with respect to these coordinates as ∫∫∫ dz dr dθ where the bounds of integration are 0<=θ<=2π, 0<=r<=3, and 2<=z<=14-r.

The volume of the solid can be found using a triple integral in cylindrical coordinates. First, we need to identify the boundaries of the solid. From the cylinder equation, we see that x² + y² = 9, which in cylindrical coordinates converts to r^2 = 9, so 0<=r<=3. Then, from the plane equations y + z = 14 and z=2, we can determine that in cylindrical coordinates, 2<=z<=14-r.

Therefore, the volume V can be found by:

V = ∫∫∫ dz dr dθ

with bounds for integration being 0<=θ<=2π, 0<=r<=3, and 2<=z<=14-r.

Running this triple integral will provide the volume of the solid.

To find what percent 187.05 is of 645, one can use the following formula:

[tex]\[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 \][/tex]

In this case, the Part is 187.05 and the Whole is 645. Plugging these values into the formula gives:

[tex]\[ \text{Percentage} = \left( \frac{187.05}{645} \right) \times 100 \][/tex]

Now, calculate the fraction:

[tex]\[ \text{Percentage} = \left( \frac{187.05}{645} \right) \times 100 = \left( 0.29155 \right) \times 100 \][/tex]

[tex]\[ \text{Percentage} = 29.155 \][/tex]

Therefore, 187.05 is approximately 29.155% of 645. To express this as a fraction, one can write:

[tex]\[ \text{Percentage} = \frac{187.05}{645} \times 100 = \frac{18705}{645} \approx 29.155\% \][/tex]

To get the exact fraction, we can simplify:

[tex]\[ \text{Percentage} = \frac{187.05}{645} \times 100 = \frac{18705}{645} \times \frac{20}{20} = \frac{374100}{12900} \][/tex]

Simplifying the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 300, we get:

[tex]\[ \text{Percentage} = \frac{374100 \div 300}{12900 \div 300} = \frac{1247}{430} \][/tex]

So, the exact fraction representing the percentage is:

[tex]\[ \text{Percentage} = \frac{1247}{430} \times 100 \][/tex]

[tex]\[ \text{Percentage} = \frac{1247}{4.3} \][/tex]

[tex]\[ \text{Percentage} = 29.00 \% \][/tex]

Thus, 187.05 is exactly 29% of 645.
