Answer: a) A'=(2, 3), B'=(-2,3), C'=(-2,-3) D'=(2,-3)

b) the measure of each angle is 90 degrees.

Step-by-step explanation:

a) To find the coordinates you need to know that (x,y) is changed to (-y,x). This means that they are flipped and changed from either negative to positive or positive to negative.

b) Each angle is 90 degrees because that shape is a rectangle with all equal right angles.  

The coordinates of the vertices of rectangle A'B'C'D' after rotating rectangle ABCD 90° about the origin are A'(-2,-3), B'(-2,3), C'(-2,-3), and D'(2,-3). All angles in rectangle A'B'C'D' measure 90°.

When a point is rotated 90° about the origin, the new coordinates can be found using the formula (y, -x). Therefore, applying this to each vertex of the rectangle, A'(3,-2) becomes A'(-2,-3), B'(3, 2) becomes B'(-2,3), C'(-3, 2) becomes C'(-2,-3) and D'(-3, -2) becomes D'(2,-3).

Since A'B'C'D' is a rectangle, all its angles are right angles. This means all the angles measure 90°.

Answer: 55 lbs of $0.40 and 45 lbs of $1.40

Step-by-step explanation:

Let's say that we have two buckets, one that weighs x pounds and the candies in it are $0.40 per pound and another that weighs 100-x pounds (because we know the two added together must be 100 pounds) and the candies in it are $1.40 per pound.

There is a third bucket that is made when you combine the two, it weighs 100 pounds and the candies in it are $0.85. Multiply the cents per pound by the pounds of the candy for each bucket and you get this equation:

0.4 * x + 1.4 (100-x) = 0.85 * 100

Solve!

0.4x + 140 - 1.4x = 85

-x + 140 = 85

-x = -55

x = 55

From this we get that 100 - x = 45.

So, the answer is 55 lbs of $0.40 and 45 lbs of $1.40

ANSWER: 55 lbs of $0.40 and 45 lbs of $1.40

-x = -55

x = 55

From this we get that 100 - x = 45.

So, the answer is 55 lbs of $0.40 and 45 lbs of $1.40

Answer:

49 blue marbles

Step-by-step explanation:

From the question we are given;

We need to determine the number of blue marbles;

Assuming the number of red marbles is x

Then, blue marbles will be 5x + 4

Therefore;

x + 5x + 4 = 58

6x + 4 = 58

6x = 54

  x = 9

5x + 4 = 5(9) + 4 = 49

Therefore, the red marbles are 9 while the blue marbles are 49

Hence there are 49 blue marbles

Answer:

n = 4

Step-by-step explanation:

Solve using the distributive property. This means you can multiply the number outside the brackets with each number inside the brackets. Then isolate "n" by moving all other numbers to the right side, leaving "n" alone on the left.

–2(5n + 7) + 8n = 2(1 – 3n)        Distribute

(5n)(-2) + (7)(-2) + 8n = (1)(2) – (3n)(2)  Multiply with each number in brackets

–10n + (–14) + 8n = 2 – 6n        Remove brackets around –14

–10n – 14 + 8n = 2 – 6n        Adding a negative is subtracting it's positive

–14 –2n = 2 – 6n        

–14 + 14 –2n = 2 + 14 – 6n        Add 14 to both sides

–2n = 16 – 6n        

–2n + 6n = 16 – 6n + 6n        Add 6n to both sides

4n = 16        

4n/4 = 16/4        Divide both sides by 4

n = 4        Solved for "n"

Check answer by substituting "4" whenever there is "n" in the original equation. Then solve each side.

–2(5n + 7) + 8n = 2(1 – 3n)

–2(5(4) + 7) + 8(4) = 2(1 – 3(4))         Solve inside brackets

–2(20 + 7) + 32 = 2(1 – 12)         Distribute

(20)(–2) + (7)(–2) + 32 = (1)(2) – (12) (2)        Multiply where necessary

–40 + (–14) + 32 = 2 – 24        Simplify

–22 = –22        Same answer

Answer:

Hours inequality (solution set): 0 ≤ x ≤ 7

Cost inequality: $2 ≤ y ≤ $100

Step-by-step explanation:

The babysitter charges $14 dollars per hour + bus fare

Price per hour = $14

Bus fare = $2

Mr. Tyler wants to spend no more than $100

Subtract the bus fare from the total amount, as that will not contribute to the babysitter's hours

$100 - $2 = $98

Divide by $14 per hour

$98 ÷ $14 = 7 hours

The maximum amount of time that Mr. Tyler could hire the babysitter for is 7 hours

This means that the hours cannot be greater than 7. It is given that x cannot be less than 0, because the babysitter cannot work negative hours.

0 ≤ x ≤ 7

This inequality shows that the Mr. Tyler will not have the babysitter work for less than 0 hours, or more than 7 hours. He will have to pay $2 minimum, or $100 max. Below is the inequality to represent this:

(y represents amount Mr. Tyler will pay)

$2 ≤ y ≤ $100

Total surface area of the square pyramid is 1476 cm².

Step-by-step explanation:

Total surface area of a pyramid = 12pl + B. Here p is perimeter of the base which is a square = 4 × side, l is the slant height and B is the area of the base = side²

Find perimeter of the base

⇒ p = 4 × side = 4 × 6 = 24 cm

Find the slant height of the prism. l² = height² + (side/2)² (Based on Pythagoras Theorem)

⇒ l² = 4² + (6/2)² = 16 + 9 = 25

⇒ l = √25 = 5 cm

Find the area of the base of the pyramid.

⇒ B = side² = 6² = 36 cm²

Calculate total surface area of the pyramid.

⇒ TSA = 12 × 24 × 5 + 36 = 1440 + 36 = 1476 cm²

Answer:

A parabola with an x-intercept of (3, 0)  

Step-by-step explanation:

We can immediately rule out the first and third options, because the equation of a second degree function is a parabola.

Your equation is

ƒ(x) = x² - 6x + 9 = 0

We can factor this equation as

ƒ(x) = (x - 3)²

The parent parabola, y = x², has its x-intercept at (0,0).

Your function subtracts three from x, so the intercept is shifted three units to the right.

The graph of your function is a parabola with an x-intercept of (3, 0).

The figure below shows the graph of your function shifted three units by subtracting three from x.

To find out how long it took Juan to finish, we add the time differences to Jesse's time. Tim finished 12 seconds faster than Jesse and Juan finished 8 seconds faster than Tim.

To find out how long it took Juan to finish, we need to add the time differences to Jesse's time. First, we know that Tim finished 12 seconds faster than Jesse, so we can add 12 seconds to Jesse's time which becomes 2 minutes and 19 seconds. Next, we know that Juan finished 8 seconds faster than Tim, so we can add 8 seconds to Tim's time which becomes 2 minutes and 27 seconds. Therefore, it took Juan 2 minutes and 27 seconds to finish the race.

Answer:

d=2

Step-by-step explanation:

We can use the given information to write down two equations that describe the ages of Kevin and Daniel.

Let Kevin's current age be k and Daniel's current age be d.

k=4d

k=d+6

Now we have two independent equations, and we can solve for our two unknowns.

Since we are looking for d, and both of our equations have k alone on one side, this is a convenient time to use elimination.

Subtracting the second equation from the first equation, we get:

0=4d-(d+6)

which combines the information about d from both of our original equations.

Solving for d, we get: 3d = 6.

Answer:

The value of given expression is 1.

Step-by-step explanation:

Consider the given expression is

[tex]\dfrac{e}{4}+2f-3[/tex]

When e=12 and [tex]f=\dfrac{1}{2}[/tex].

Substitute e=12 and [tex]f=\dfrac{1}{2}[/tex]  in the given expression.

[tex]\dfrac{12}{4}+2(\dfrac{1}{2})-3[/tex]

On simplification we get

[tex]3+1-3[/tex]

[tex]1[/tex]

Therefore, the value of given expression is 1.

The evaluated result of the expression e/4 + 2f - 3, given specific values e = 12 and f = 5, is 13.

To evaluate the expression e/4 + 2f - 3, we need to follow a systematic procedure. First, we replace 'e' and 'f' with their respective values or expressions, if provided. Once these values are substituted, we perform the mathematical operations in the given order: division, multiplication, and subtraction.

Assuming we have specific values for 'e' and 'f', let's say e = 12 and f = 5. Substituting these values into the expression, we get:

e/4 + 2f - 3

= 12/4 + 2 * 5 - 3

Now, we simplify each part of the expression step by step:

12/4 = 3 (division)

2 * 5 = 10 (multiplication)

3 - 3 = 0 (subtraction)

Summing up the simplified components, we get:

3 + 10 - 0

Finally, performing the remaining additions and subtractions:

3 + 10 = 13

13 - 0 = 13

So, when e = 12 and f = 5, the evaluated result of the expression e/4 + 2f - 3 is 13.

Answer:

The values of x and y in the diagonals of the parallelogram are x=0 and y=5

Step-by-step explanation:

Given that ABCD is a parallelogram

And segment AC=4x+10

From the figure we have the diagonals AC=3x+y and BD=2x+y

By the property of parallelogram the diagonals are congruent

∴ we can equate the diagonals AC=BD

That is 3x+y=2x+y

3x+y-(2x+y)=2x+y-(2x+y)

3x+y-2x-y=2x+y-2x-y

x+0=0 ( by adding the like terms )

∴ x=0

Given that segment AC=4x+10

Substitute x=0  we have AC=4(0)+10

=0+10

=10

∴ AC=10

Now (3x+y)+(2x+y)=10

5x+2y=10

Substitute x=0, 5(0)+2y=10

2y=10

[tex]y=\frac{10}{2}[/tex]

∴ y=5

∴ the values of x and y are x=0 and y=5

12.5 = 3.5 (3)+2

12.5 = 3 (2.5)+5

Step-by-step explanation:

The distance at which the cost of each taxi is the same is 6 miles.

The trip would cost $23.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 - 9 is an equation.

We have,

Taxi A:

c = 3.5d + 2

Taxi B:

c = 3d + 5

Where c is the cost of the taxi after d distance.

Now,

The cost of the taxi is the same.

3.5d + 2 = 3d + 5

3.5d - 3d = 5 - 2

0.5d = 3

d = 3/0.5

d = 30/5

d = 6

The cost of the taxi at d = 6.

c = 3.5d + 2 = 3.5 x 6 + 2 = 21 + 2 = 23

c = 3d + 5 = 3 x 6 + 5 = 18 + 5 = 23
