Answer:
38.4
Step-by-step explanation:
We have 8/2.5=3.2 What does this mean? Well, it means that (if the miles are porportional to the dogs) that means he will see 3.2 as many dogs. So, we have 12*3.2=38.4, or 38 if the homework is asking for a rounded number. Hope I helped!
Larry sees 12 dogs per 2.5 miles.
Your trying to find out how many dogs Larry sees in 8 miles.
[tex]\frac{2.5}{12} = \frac{8}{x}[/tex]
So you want to find x.
To go from 2.5 to 8, you have to multiply by 3.2
So do the same thing to the denominator; 12 × 3.2=38.4
Since there are 38.4 dogs, you have to round down because 0.4 dogs is no dog.
Larry sees 38 dogs in 8 miles.

A shop has a 3 for 2 offer on chocolate bars The normal price of a chocolate bar is 72p Sian gets 3 chocolate bars from the shop using this offer How much does she spend Give your answer in pounds
Answer:
1.44 pounds
Step-by-step explanation:
From the above question, we are told that:
The shop has 3 for 2 offer on chocolate bars going on .This means a customer can buy 2 chocolates get 1 free, for the price of 2 chocolates, a customer can get 3 chocolates.
If the price of 1 chocolate bar = 72p
2 chocolate bars =
72p × 2
= 144p
Hence, Sian spends 144p
We are asked to convert our answer to pounds
The symbol p represent pence in money form
Hence,
100p(pence) = 1 pound
144p(pence) = x
100p × x = 144p × 1
x = 144p/100p
x = 1.44 pounds
Therefore, Sian spends 1.44 pounds

Suppose the population of a town is 8,200 and is growing 4% each year, what is the population expected to be in 10 years
Answer:
12,138 people
Step-by-step explanation:
Create an equation using the basic exponential growth equation:
y = a(1 + r)^t, where a is the initial amount, r is the growth rate as a decimal, and t is the amount of time in years.
Plug in the values we know
y = a(1 + r)^t
y = 8200(1 + 0.04)^10
y = 8200(1.04)^10
= 12,138 people
Can someone answer these three questions? Thank you
Answer:
D, B, B
Step-by-step explanation:
Question 1: D
We need to solve for x.
z = 2π * (x / y)¹/²
z = 2π * (x¹/² / y¹/²)
z = 2π * (√x / √y)
z = √x * 2π / √y
√x = √y * (z / 2π)
x = y(z /2π)²
Question 2: B
(x⁵ + x⁴) / (x³ + x²)
= x⁴(x + 1) / x²(x + 1)
= x⁴ / x² = x⁽⁴⁻²⁾ = x²
Question 3: B
Let's try out A. Substituting p = 1, q = 1:
√1 * √1 = √(1 + 1)
1 * 1 = √2
1 = √2 FALSE
Let's try B. Substituting p = 2, q = 2:
√2 * √2 = √(2 + 2)
√4 = √4 TRUE so the answer is B.

Mr. and Mrs. Nelson are going to build a new home. They need to have working drawings of their house plans created by a design firm. They will choose between Rock the House Digital Designs and Elegant Home Architects. Rock the House Digital Designs charges $500.00 for the initial consultation with the Nelsons, plus $50.00 for every additional hour of work for the house plans. Elegant Home Architects charge $75.00 per hour for the house plans. Let ℎ represent the number of hours for which Mr. and Mrs. Nelson hire the design firm. Which of the following statements are true? Select all that apply. he expression 50ℎ represents the total charge for Rock the House Digital Designs.
a.The expression 75ℎ represents the total charge for Elegance Home Architects.
b.The expression 500 + 75ℎ + 50ℎ represents the total amount the Nelsons will spend working drawings of their new house plans.
c.If the Nelsons hire the design firm for 15 hours, then Elegance Home Architects will be cheaper.
d.If the Nelsons hire the design firm for 25 hours, then Rock the House Digital Designs will be cheaper.
Answer:
The correct statements are (a), (c) and (d).
Step-by-step explanation:
The information provided is:
Rock the House Digital Designs charges $500.00 for the initial consultation with the Nelsons plus $50.00 for every additional hour of work for the house plans.Elegant Home Architects charge $75.00 per hour for the house plans.The variable h represent the number of hours for which Mr. and Mrs. Nelson hire the design firm.The total charge for Elegance Home Architects, if the Nelsons choose them will be:
Total for Elegance = 75 × h = 75h.
Suppose the Nelsons hire the design firm for 15 hours.
Total for Elegance = 75 × h = 75 × 15 = $1,125
Total for Rock = 500 + (50 × h) = 500 + (50 × 15) = $1,250
So, the Elegance Home Architects will be cheaper.
Suppose the Nelsons hire the design firm for 25 hours.
Total for Elegance = 75 × h = 75 × 25 = $1,875
Total for Rock = 500 + (50 × h) = 500 + (50 × 25) = $1,750
So, the Rock the House Digital Designs will be cheaper.
Thus, the correct statements are (a), (c) and (d).

B) were trained over the past two years, and they had
C) were trained over the past two years and they have
D) had been trained over the past two years and that they had
E) had been trained over the past two years and that they have
Answer:
D) had been trained over the past two years and that they had
Step-by-step explanation:
In the context, the sentence speaks of something that happened in the past, so 'had been' is required and also it speaks of parallelism of events, as an estimation is being made so, parallelism should be maintained.
Hence, option (D) satisfies the two requirements. And eliminate option A, B, C and E.
Thus, (D) is correct.

Find the measure of b+d. A. 74 B. 90 C. 32 D. 58
Answer:
B. 90°
Step-by-step explanation:
Quadrilateral inscribed in the circle with center O is a cyclic quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
Therefore,
(b + d) + (32° + 58°) = 180°
b + d + 90° = 180°
b + d = 180° - 90°
b + d = 90°

Determine the domain of the function. f as a function of x is equal to the square root of x plus one divided by x plus four times x minus six.
Answer:
a)
Step-by-step explanation:
We have been given a function . We are asked to find the domain of our given function.
We can see that our given function is a rational function and numerator of our given function is a square root.
To find the domain of our given function, we will find the number that will make our denominator 0 and the domain of square root function will be the values of x that will make our numerator non-negative.
Undefined points for our given function:
The domain of denominator is all values of x, where x is not equal to negative 4 and positive 6.
Non negative values for radical:
The domain of numerator is all value of x greater than or equal to negative
Upon combining real regions and undefined points for our given function, the domain of our given function will be all values of x greater than or equal to negative 1, where x is not defined for 6.
Therefore, domain of our given function is .
A book sold 35,300 copies in its first month of release. Suppose this represents 6.3 of the numbers sold to date. How many copies have been sold to date?
Answer:
560,317.460
Step-by-step explanation:
The computation of copies that have been sold is shown below:-
we assume the number of copies is x
So, the number of copies in the first month is
= [tex]\frac{6.3}{100} x[/tex]
As per the situation the number of sold copies is 35,300 so the equation will be
[tex]\frac{6.3}{100} x = 35,300[/tex]
[tex]6.3x = 35,300\times 100[/tex]
[tex]x = \frac{35,300\times 100}{6.3}[/tex]
after solving the above equation we will get the number of copied that have been sold to date
= 560,317.460

In Ms. Ford's classroom 13 students are able to fit comfortably into a 5 by 5 square.
Use this value to estimate the size of a crowd that is 10 feet deep on both sides of the street standing
along a 1-mile section of a parade route.
Answer:
Estimate of crowd is 27456.
Step-by-step explanation:
Given that a square of 5 by 5 can have 13 students.
Area of a square = [tex]side^2[/tex] = 25
Area of 25 can have 13 students.
Now, it is given that 10 feet square are used for crowd.
Area of square of side 10 feet = 100
So, area of 100 can have 13 [tex]\times[/tex] 4 = 52 people from crowd
Now, it is given that the parade route is 1 mile long.
1 mile = 5280 feet
1 mile = 528 [tex]\times[/tex] 10 feet
It means that there are 528 number of such squares on the 1 mile section of the parade route.
Kindly refer to the attached image as well.
So, number of people or the estimate of the size of crowd is:

Suppose that a spotlight is used for lighting objects at many different distances and that the area A of the light circle produced is related to the distance x to the lighted object by A=0.1x^2.
a. If the spotlight produces 250 lumens of light energy, what function gives the intensity of the light I, (in lumens per square foot) as a function of the distance x in feet from the spotlight to its target?
b. Write and solve equations that match these questions about the light intensity from the spotlight.
i. What is the intensity of light on an object that is 20 feet from the spotlight source?
ii. How far from the spotlight is an object that recieves 100 lumens of light per square foot?
Answer:
Intensity = 2500/x^2
6.25 lumem
5 Feets
Step-by-step explanation:
Given the following :
Area (A) = 0.1x^2
Intensity, Energy and Area are related by the formular :
Intensity = power / Area
A) If 250 lumens of light energy is produced :
Intensity (I) = 250 / 0.1x^2
Intensity = 2500/x^2
x = distance
B) USING THE EQUATION :
1) What is the intensity of light on an object that is 20 feet from the spotlight source?
x = 20
Intensity = 2500/x^2
Intensity = 2500/20^2
Intensity = 2500/400
Intensity = 6.25 lumen
11) How far from the spotlight is an object that recieves 100 lumens of light per square foot?
Intensity = 100
100 = 2500 / x^2
100x^2 = 2500
x^2 = 2500/ 100
x^2 = 25
x = 5 Feets
