Jill bought a pound of strawberries for $4.00. What is the price, in dollars, per ounce of strawberries? (1lb = 16 oz)

Kasey has $53.63 withheld from her weekly paycheck of $865 for Social Security, which is calculated by multiplying her weekly pay by the Social Security tax rate of 6.2%.

The question asks us to calculate how much is withheld from Kasey's paycheck for Social Security.

With a weekly pay of $865, we need to find 6.2% of that amount since that is the percentage deducted for Social Security taxes.

To find this amount, we multiply $865 by 0.062.

Calculation: $865 × 0.062 = $53.63

Therefore, $53.63 is withheld from Kasey's paycheck each week for Social Security.

The other endpoint V of the line segment is found by doubling the coordinates of the midpoint M and subtracting the coordinates of the known endpoint W. Applying this method, the coordinates of V are (10, 10).

In Mathematics, the midpoint formula allows us to find the midpoint coordinates of a line segment. Given that M(9, 8) is the midpoint and W(8, 6) is one endpoint, you can find the coordinates of the other endpoint V using the formula:
V = (2M - W).

So, simply double the coordinates of the midpoint and subtract the coordinates of the known endpoint. This determines the coordinates of the other endpoint. For the given question, we apply this to get:

Vx = 2*9 - 8 = 10,
Vy = 2*8 - 6 = 10.

Answer:

x= 2.2​

Step-by-step explanation:

-0.45х + 0.33 = -0.66

Subtract .33 from each side

-0.45х + 0.33-.33 = -0.66-.33

Step-by-step explanation:

We have the following expression [tex]\frac{2}{8} = \frac{n}{20}[/tex] and we must solve for variable n.

To solve the equation multiply by 20 on both sides of the equality and you will get the following

[tex]20*\frac{2}{8} = 20*\frac{n}{20}[/tex]

Answer:

Step-by-step explanation:

f(0) - f(-3) = area under f'(x) from x=0 to x=3.

We can find the area under f'(x) in this interval by finding the area of the triangle formed by the line.

A = 1/2 b h

A = 1/2 (3) (3)

A = 4.5

f(0) - f(-3) = 4.5

Since f(0) = 7:

7 - f(-3) = 4.5

f(-3) = 7 - 4.5

f(-3) = 2.5

Answer:

$20(.85)(1.06) = $18.02

Answer:

Their point of intersection will always be on the line y = x.

Step-by-step explanation:

We have a function f(x) and its inverse is the function f⁻¹(x).

The domain and range of a function replaces each other for the inverse of that function.

So if f(x) and f⁻¹(x) are inverse of each other

and f(a) = b

then a = f⁻¹(b)

Another example to make it clear is that

f(5) = 25

f⁻¹(25) = 5

The function and its inverse will intersect each other at the point where f(x) = f⁻¹(x) which is only possible when a = b.

Hence, a function and its inverse will always intersect at a point on the line x=y.

Complementary means they add to 90°

f=90-g

f=4g

4g =90-g

5g=90

g=18

f=4g=4(18)=72

Answer: f=72°, g=18°

Angles (2x + 14)° and (x + 7)° are complementary angles.

If two angles are complementary, then they add up to 90°.

Answer:

296 inches

Step-by-step explanation:

The perimeter is the sum of sides of a rectangle

As the length is in feet while the width is in inches, a unit conversion must take place

As 1  feet  equals to 12 inches

9 feet would be equal to 12*9=108 inches

The perimeter of a rectangle= 2(width)(length)

= 2(108)(40)

=296 inches

By applying the principle of inclusion-exclusion and considering students in History, we find that 3 students are in neither Math Competition classes nor Geometry.

To determine how many students are in neither Math Competition classes nor Geometry, we can use the principle of inclusion-exclusion. We have 50 students in total, with 25 in Math Competition classes and 29 in Geometry. However, since 19 students are in both classes, they were counted twice when we added the students in Math Competition classes and Geometry together. Thus, we subtract the number of students in both to avoid double-counting:
(25 + 29 - 19) = 35 students are in at least one of the math classes. Additionally, 12 students are in a History class and no math classes. Therefore, the number of students in at least one class (math or history) is 35 + 12 = 47.

Finally, to find the number of students in neither class, we subtract the number of students in at least one class from the total number of students:
50 - 47 = 3 students are in neither Math Competition classes nor Geometry.

Answer:

$6240

Step-by-step explanation:

Find the rate by dividing property tax by the appraisal value.

[tex]\frac{3840}{160000}=0.024[/tex]

Now multiply the appraised value by this rate to find the property tax.

[tex]260000*0.024=6240[/tex]

The property tax on a home appraised at $260,000 is $6,240.

To find the property tax on a home appraised at $260,000, we can set up a proportion using the given information. The property tax on a $160,000 home is $3,840, so we have:

$160,000 : $3,840 = $260,000 : x

Using cross-multiplication, we can solve for x:

x = ($260,000 * $3,840) / $160,000

Calculating this, we find that the property tax on a home appraised at $260,000 is $6,240.

Answer:

A. y - 7 = -4(x + 2)

Step-by-step explanation:

Insert the coordinates into the formula with their CORRECT signs. Remember, in the Point-Slope Formula, y - y₁ = m(x - x₁), all the negative symbols give the OPPOSITE term of what they really are. In addition, I recall that perpendicular lines have OPPOSITE MULTIPLICATIVE INVERSE [RECIPROCAL] rate of changes [slopes], so -4 really should be replaced with ¼, but if your assignment says otherwise, then this is the answer.

To find the equation of a line perpendicular to y=-4x -1 that passes through (-2, 7), we take the negative reciprocal of -4 to find the slope of the perpendicular line. Plugging in the values (-2, 7) and 1/4 for the slope, we get the equation y - 7 = 1/4(x + 2). Therefore, the correct answer is A. y - 7 = -4(x + 2).

To find the equation of a line perpendicular to a given line, we need to determine the slope of the perpendicular line. The given equation is in the form y = mx + b, where m represents the slope. The slope of the given line is -4. To find the slope of the perpendicular line, we take the negative reciprocal of -4, which is 1/4. Now that we have the slope, we can use the point-slope form of a linear equation, which is y - y1 = m(x - x1), where (x1, y1) is a point on the line. Plugging in the values (-2, 7) for (x1, y1) and 1/4 for the slope, we get the equation y - 7 = 1/4(x + 2). Therefore, the correct answer is A. y - 7 = -4(x + 2).

Final answer:

The student missed the conversion from minutes to hours. The correct conversion is 26 hours × 60 minutes/hour × 60 seconds/minute, which equals 93,600 seconds.

Explanation:

Identifying the Missed Conversion Step

The student was attempting to convert 26 hours into seconds but arrived at an incorrect result of 1560 seconds. The error occurred because the student skipped the correct conversion ratio between minutes and hours. For such conversions, it is essential to use the correct conversion factors: 60 minutes per hour and 60 seconds per minute.

Correct Conversion Process

To convert 26 hours to seconds:

First, convert hours to minutes: 26 hours × 60 minutes/hour = 1560 minutes.

Then, convert minutes to seconds: 1560 minutes × 60 seconds/minute = 93,600 seconds.

Therefore, the correct number of seconds in 26 hours is 93,600 seconds.
