Answers

Figure B is not a scale copy of figure A. The answer is NO. The corresponding lengths of both figures have different ratios.

How to Determine a Scale Copy of a Figure?

If a figure is the scale copy of another figure, the corresponding side lengths of both figures would be proportional to each other, which means their ratios would be the same.

From the figure given, the ratios of their side lengths are:

18/9 = 2

12/12 = 1

30/15 = 2

This shows that their ratios are not the same.

Therefore, we can conclude that figure B is not a scale copy of figure A. The answer is NO. The corresponding lengths of both figures have different ratios.

Solve the system of equations.
3x + 48 + 32 = 9
3x+3y +32=3
2x + 4y + 32 = 8

Answers

Answer:

It will be (x=1.y=6.z=-6

Answer:

Choice b

(x = 1,  y = 6, z = -6)  

Step-by-step explanation:

The system of equations is

3x + 4y  + 3z = 9     (1)
3x + 3y +  3z =  3      (2)

2x + 4y + 3z =  8      (3)

Subtract (2) from (1) to eliminate the 3x and 3y terms and solve for y

(1) - (2)

==> 3x + 4y  + 3z - (3x + 3y +3z) = 9 - 3

==> 3x + 4y + 3z - 3x - 3y - 3z = 6

(3x-3x) + (4y-3y) + (3z-3z) = 6

4y - 3y = 6

y = 6

Subtract (3) from (1) to isolate the x term

(3x - 2x) + (4y-4y) + (3z-3z) = 9 -8

x = 1

Divide equation (2) on both sides by 32 to eliminate the coefficients

Equation (2) ÷ 3

==> (3x + 3y + 3z) / 2 = 3/3

==> x + y + z = 1    (4)

Substitute the values of x and y in Equation (4)

1 + 6 + z = 1

7 + z = 1

Subtract 7 from both sides

==> z = 1-7 = 6

Answer:
(x = 1,  y = 6, z = -6)

The area of a square is the square of the length of a side is a^2.

The quantity of space occupied within the square can be used to calculate the size of a square using mathematics. We'll go over the equation for calculating the square's area below. It is mainly known for its geometric quadrilaterals. The simplest definition of a square is a regular polygon with four equal sides. A square has all the same facts and characteristics as regular polygons.

The number of square units that are anticipated to fill a square is used to describe the area of a square. The area is typically defined as the area included by the confines of a level article or 2D figure.

At its farthest, the earth is about 9.52 * 10 ^ 7 miles from the sun. Light travels from the sun at a speed of around 1.2 * 10 ^ 6 miles per minute. How many minutes does it take for the light to travel from the Sun to the Earth? Show your calculations and write in standard form.

Answers

The number of minutes to take for the light to travel from the sun to the earth is 7.93×[tex]10^{1}[/tex] minutes.

The distance between the earth and sun=9.52×[tex]10^{7}[/tex] miles

The speed of the light from sun=1.2×[tex]10^{6}[/tex] miles per minutes

Speed=Distance/Time

Time= Distance/Speed

Substitute the values in the equation

Time taken for the light to travel from the sun to the earth = The distance between the earth and sun ÷ The speed of the light from sun

Substitute the values in the equation

=9.52×[tex]10^{7}[/tex]÷ 1.2×[tex]10^{6}[/tex]

=(9.52÷1.2)×[tex]10^{7-6}[/tex]

The cost of a taxi ride, in dollars, is $2 for the first quarter mile plus $0.40 for each quarter mile after that. Jameel cannot
afford to spend more than $20 on a taxi ride.
The equation 2 + 0.4(4m - 1) = 20 can be used to find m, the distance, in miles, that Jameel can travel for $20. What
is the maximum distance?
A) 13.5 miles
B 16.0 miles
C11.5 miles
(D) 14.0 miles

Answers

The maximum distance Jameel can travel is 11.5 miles

How to determine the maximum distance?

The equation that determines the distance is given as

2 + 0.4(4m - 1) = 20

Subtract 2 from both sides of the equation

So, we have

0.4(4m - 1) = 20 -2

Evaluate the like terms

So, we have

0.4(4m - 1) = 18

Divide both sides by 0.4

So, we have

(4m - 1) = 18/0.4

Evaluate the quotients

So, we have

(4m - 1) = 45

Remove the bracket

So, we have

4m - 1 = 45

Add 1 to both sides of the equation

4m = 46

Divide both sides of the equation by 4

So, we have

x = 11.5

Hence, the maximum distance Jameel can travel is 11.5miles

Answers

The function of  f(x) = (x+4)³ + 3 is one-to-one  then the value of

[tex]f^{-1} (x) = \sqrt[3]{x} - 4[/tex] and,

[tex]f^{-1} (2) = -2.7401[/tex]

The function f(x) = (x+4)³ + 3

Let us assume,

y = (x+4)³ + 3

What is Invertible function?

A function is said to be invertible when it has an inverse. It is represented by [tex]f^{-1}[/tex]. Condition for a function to have a well-defined inverse is that it be one-to-one and Onto or simply bijective.

Then,

y = (x+4)³   and    y = 3

Therefore the inverse of y = 3 is the line x = 3

We can solve,

y = (x+4)³

The solution of Inverse function,

So,

[tex]\sqrt[3]{y} = x+4[/tex]

We can get,

[tex]x = \sqrt[3]{y} -4[/tex]

So the inverse of y is [tex]\sqrt[3]{x} -4[/tex]

f(x) = (x+4)³

So the inverse of f(x) is [tex]\sqrt[3]{x} -4[/tex]

Therefore, [tex]f^{-1}( x)[/tex] = [tex]\sqrt[3]{x} -4[/tex]

Then f(x) = 2

[tex]f^{-1} (x) = \sqrt[3]{x} - 4[/tex]

We can substitute f(x) = 2

[tex]f^{-1} (2) = \sqrt[3]{2} -4[/tex]      

Since, ∛2 = 1.2599

We can substitute this value,

[tex]f^{-1} (2) = 1.2599-4[/tex]

[tex]f^{-1} (2) = -2.7401[/tex]

Therefore,

The value of ,

Find the reference angle for -7pi/5

Answers

Answer:

When the terminal side is in the first quadrant (angles from 0° to 90°), our reference angle is the same as our given angle. This makes sense, since all the angles in the first quadrant are less than 90°. So, if our given angle is 33°, then its reference angle is also 33°.

When the terminal side is in the second quadrant (angles from 90° to 180°), our reference angle is 180° minus our given angle. So, if our given angle is 110°, then its reference angle is 180° – 110° = 70°.

When the terminal side is in the third quadrant (angles from 180° to 270°), our reference angle is our given angle minus 180°. So, if our given angle is 214°, then its reference angle is 214° – 180° = 34°.

When the terminal side is in the fourth quadrant (angles from 270° to 360°), our reference angle is 360° minus our given angle. So, if our given angle is 332°, then its reference angle is 360° – 332° = 28°.

Austin rented a truck for one day. There was a base fee of $17.99, and there was an additional charge of 73 cents for each mile driven. Austin had to pay $120.92 when he returned the truck. For how many miles did he drive the truck?

Answers

The miles for which  Austin drove the truck  is 141 miles

It is given that Austin rents a truck for one day

The daily rental base fee of the truck is $17.99

It is also given that additional charge of 73 cents per mile is charged.

It is also to be noted that 1$ =100 cents

Therefore, 73 cents in the form of dollar is 0.73$

Now it is given that total bill that is paid is $120.92

Now the total number of miles travelled by Austin is total bill minus the base fee and 73 cents multiplied by miles

Let the miles travelled by Austin be 'x'

Therefore, Miles travelled by Austin = 120.92$-17.99$

                                     0.73 x =(120.92 -17.99)  $                      

                                     x= 102.93 / 0.73

                                     x=141

Hence, the miles for which Austin drove the truck is 141 miles

A medical insurance policy requires Harold to pay the first $550 of her hospital expense. The insurance company will then pay 75% of the remaining expense. Harold estimates the total bill to be about $20,500. Apart from that Harold also had to pay 12% of $450 fee for prescription medications and a $250 late fee if she pays the bill after September 30. How much will Harold's total payment be if he pays on October 2nd?

Answers

Harold's total payment is  $5,841.50.

What is Harold's total payment?

Percentage is the  fraction of a quantity that is expressed as a number out of hundred. The sign used to represent percentages is %. Percentages are a measure of frequency.

The total bill Harold would pay is the sum of the first $550, 25% of the remaining bill, 12% of the fee for prescription medications and the late payment fee since she paid after September 30.

Amount of total bill that Harold would pay = (100 - 75)% x (20,500 - 550)

25% x 19,950 = $4,987.50

Amount of the  prescription medications Harold pays : 12% x 450 = $54

Total bill - $550 + $4,987.50 + $54 + $250 = $5,841.50
