Answer: Yes, they receive more than $82 for their job

Step-by-step explanation:

First, take 70 times 0.05% = $3.50

Then add them to equal $73.50 is their charge for the job!

Now it says that the homeowner tip 15%

So take 73.50 times 0.15% = $11.03

Then add 73.50 with 11.03 = $84.53

Yes, they receive more than $82 for their job

The investment firm's total profit is $4,000

Step-by-step explanation:

The Profit from Company A = 11% * $8,000

= 11 * $8,000/100

= $880

The Profit from Company B = 13% * $24,000

= 13 * $24,000/100

= $3,120

The total profit = $880 + $3120

= $4,000

Thus, the investment firm's total profit is $4,000

Answer:

3

Step-by-step explanation:

The right response is 21 days, minus any days that the location was unavailable or inaccessible.

This is due to the fact that taxpayers have 21 days starting from the date of the Notice of Deficiency to file a petition with the Tax Court, as per the Internal Revenue Service. However, the taxpayer can be given longer time to submit the petition if their place of residence or business was inaccessible or unavailable as a result of a natural disaster..

Upon receiving a Notice of Deficiency, the Internal Revenue Service (IRS) gives taxpayers 21 days to file a petition with the Tax Court. This petition is a formally filed motion asking the court to consider the proposed assessment of the IRS and resolve the taxpayer's disagreements with the agency.

Therefore, the right response is 21 days, minus any days that the location was unavailable or inaccessible.

After converting \(4.5 * 10^4\) to decimal format, one gets 45,000 as an answer. Thus, option (A) is the correct answer.

To convert numbers multiplied by 10 with having an exponent number to decimal format, one first needs to check the sign on the exponent.

If the sign is positive, we must shift the decimal to the right with each power of 10. The exponent indicates the number of zeros added after the number in case no decimal is used.

And if the sign is negative, we have to shift the decimal to the left with each power of 10. One has to divide the number by the number one gets after multiplying 10 by itself as many times as the exponent.

Therefore, to convert \(4.5 * 10^4\) to decimal format, we shift the decimal by 4 places and we get 45,000 as the answer.

Step-by-step explanation:

The value for x is 7π/6 and 11π/6.

sin2xsecx+2cosx=0

(2sinxcosx)(1/cosx)+2cosx=0

sinxcosx/cosx+2cosx=0

So,

2sinx+2cosx=0

2(sinx+cosx)=0

(2(sinx+cosx))²=0

4(sin²x+cos²x+2sinxcosx)=0

hence,

(sin²x+cos²x+2sinxcosx)/4=0/4

sin2x+cos2x+2sinxcosx=0

1+sin2x=0

sinx=−1/2

The final image will fit in a similar portfolio with an area of 160 square inches.

To obtain the area of a rectangle, you need to multiply its length by its width. The formula for the area of a rectangle is:

Area = Length x Width.

The dimensions for this problem are given as follows:

24 inches, 36 inches.

With the reduction with a scale factor of 1/3, the dimensions are given as follows:

8 inches,  12 inches.

With the enlargement by a factor of 1.25, the dimensions are given as follows:

10 inches and 15 inches.

Hence the area is given as follows:

15 x 10 = 150 square inches.

As the area of 150 square inches is less than 160 square inches, the final image will fit in a similar portfolio with an area of 160 square inches.

Answer:

4.00 - 0.50 = 3.50

Step-by-step explanation:

The value of p that satisfies the equation is 10. Option D

To find the value of p in the equation "One-fourth (8 minus 4p) + 2p = 12," we need to solve for p. Let's break down the steps to find the solution:

Distribute the 1/4 to the terms inside the parentheses:

(1/4) * (8 - 4p) + 2p = 12

Simplify the expression:

2 - p + 2p = 12

Combine like terms on the left side of the equation:

-p + 2p = 12 - 2

Simplify further:

p = 10

Therefore, the value of p in the equation is 10.

Looking at the given answer choices:

A) –20

B) –2

C) 5

D) 10

We can see that the correct answer is D) 10, as determined by solving the equation. The value of p that satisfies the equation is 10.

Answer:

C.  \(f(x)=(x+1)^2-4\)

Step-by-step explanation:

A. the graph is a straight line with slope 1.  It goes up/down infinitely far so the range is all real numbers.  Not A!

B. The graph is a straight line with slope -4, so, like the function in A, the range is all real numbers.  Not B!

D. The graph is an absolute value function  y = |x|, reflected over the x-axis, shifted right 3 units, then shifted down 4 units.  So the graph starts witha "vee" shape opening up, becomes a vee opening down, then ultimately gets shifted down 4 units.  The range is all real numbers less than or equal to -4.

See the attached graphs.  image2 is the function in answer choice D.

The correct statements are:

The median is six and one-fourth.

The mode cannot be determined from the given information.

The range is five and three-fourths.

The median measures the central tendency in a dataset, which is the middle value when the data is arranged in order from lowest to highest (or highest to lowest). If the dataset has an odd number of values, the median is the middle value. If there is an even number of values in the dataset, the median is the average of the two middle values.

The median is six and fourth: This statement is true based on the given information that there are 11 marks on the line plot above 6 and fourth, and 11 marks below.

The mode is seven and two-fourths: This statement is false based on the given information. The mode is the value that appears most frequently in the dataset, and there are no values that appear more than once in the given data.

The range is five and three-fourths: This statement is true based on the given information. The range is the difference between the highest and lowest values in the dataset, which in this case is 5 and three-fourths (8 minus 2 and one-fourth).

Answer:

3 : 7

Step-by-step explanation:

Ratios are Proportinalised Numbers that we can use to compare number of units relative to the other value.

Eg. 3 : 15 = 1 : 5

Given Information from the Question:

15 Child Tickets : 35 Adult Tickets

Now we reduce them to simplest form.

(15 ÷ 5) : (35 ÷ 5) = 3 : 7.

Therefore the ratio of Child Tickets to Adult Tickets is 3 : 7.

Since the graph shows the population P in a small industrial city from 1950 to 2000, we can assume that x = 0 corresponds to 1950, x = 10 corresponds to 1960, x = 20 corresponds to 1970, x = 30 corresponds to 1980, and x = 40 corresponds to 1990.

(a) To find the average rate of change of P between x = 20 and x = 40, we can use the formula:

average rate of change = (change in P) / (change in x)

The change in P between x = 20 and x = 40 is:

P(40) - P(20) = 60 - 80 = -20

The change in x between x = 20 and x = 40 is:

40 - 20 = 20

Therefore, the average rate of change of P between x = 20 and x = 40 is:

average rate of change = (-20) / (20) = -1

(b) The value of the average rate of change that we found in part (a) is -1. This means that the population of the small industrial city was decreasing at an average rate of 1 unit per year between 1990 and 1970. In other words, for every year that passed during this time period, the population decreased by an average of 1 person. This rate of decline is relatively slow, but it could have significant long-term effects on the city's economy, infrastructure, and social dynamics if it continued for a prolonged period of time.

Answer:

A

Step-by-step explanation:

I honestly couldn't tell you how to do this, I don't understand it. I just took the test and got this question correct. The answer is A, (5-7)^2.

The average velocity from t = 2s to t = 4s would be - 48 ft/s.

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that an object is thrown upward with initial velocity of 48 feet per second from a high of 120 feet. The height of the object t seconds after it is thrown is given by h(t) = - 16t² + 48t + 120.

Average rate of change of velocity with time is called average velocity. Mathematically -

v{avg.} = Δx/Δt                                                         .... Eq { 1 }

Δx = x(4) - x(2)

Δx = - 16(4)² + 48(4) + 120 - {- 16(2)² + 48(2) + 120}

Δx = - 96

Δt = 4 - 2 = 2

So -

v{avg.} = Δx/Δt = -96/2 = - 48 ft/s

Therefore, the average velocity from t = 2s to t = 4s would be - 48 ft/s.
