Answer 1

Answer:

The last one

Step-by-step explanation:

volume is v= [tex]\pi r^{2} h[/tex] . this means volume is mathematical number pi, times the (radius squared), times the height. the radius is marked at the yellow line, and the height on the side. this means you would have v = [tex]\pi[/tex][tex](x+2)^{2}[/tex][tex](3x+8)[/tex]

first, lets work out [tex](x+2)^{2}[/tex]. we can rewrite this as (x+2)(x+2). we are going to use a system called FOIL. this stands for First Outside Inside Last. This means we are going to take the first number from both and multiply them together, then the outside, inside, and last. so, for first, we will multiply x and x and then we have [tex]x^{2}[/tex], for outside we multiply x and 2 and we get [tex]2x[/tex], for inside we multiply 2 and x and we get [tex]2x[/tex], and for last we multiply 2 and 2 and we get [tex]4[/tex]. then we add all these together. [tex]x^{2} + 2x + 2x + 4[/tex]. then simplify like terms to get

[tex]x^{2} + 4x + 4[/tex]. now, we can't forget about our times [tex]\pi[/tex] and (3x+8)

this means we have to multiply [tex]x^{2} + 4x + 4[/tex] by those two.

it would look like this: ([tex]x^{2} + 4x + 4[/tex])(3x+8)[tex]\pi[/tex]

so now we are going to multiply the other two sets of parentheses

we multiply each number from the first set to each number in the second set.

sold this year is 125% of the cars sold last year. About how many cars were sold this year
sold this

Answers

Answer:

415,000

Step-by-step explanation:

First, find the decimal equivalent of 125%. To do this, divide 125 by 100 or move two decimal places to the right: 125/100 = 1.25

Now multiply the amount of cars sold last year, 332,000, by the percentage decimal, 1.25: 332,000 x 1.25 = 415,000

A group of 10 people is choosing a chairperson and vice-chairperson. They put all 10 people's names into a hat. The first name drawn becomes chair. The second name drawn becomes vice-chair. How many possible combinations of chair and vice-chair are there?

a.19
b.90
c.100
d.10! (10 factorial)

Answers

Answer:

Step-by-step explanation:

As there are 10 people and choosing chairperson occurs first as an independent event

=> The number of possible chairperson is 10.

After the chairperson is chosen, the number of names left in the hat is 9

=> There are 9 possible vice-chair.

However, the names left in the hat depends on which name is elected as chairperson

=> Choosing vice-chair is a an event dependent on the first event.

=> The number of possible combinations of chair and vice chair would be:

which is bigger 12 pints or 6 cups

Answers

Answer:

12 pints is bigger

Explanation: A pint is two cups, so 12 pints would be 24 cups.

The correct answer is that 12 pints is bigger than 6 cups.

To understand why, let's look at the conversion factors between pints and cups. In the United States Customary System, 1 pint is equivalent to 2 cups.

Now, let's calculate the volume of 12 pints in cups:

[tex]\[ 12 \text{ pints} \times \frac{2 \text{ cups}}{1 \text{ pint}} = 24 \text{ cups} \][/tex]

Comparing 24 cups (which is the equivalent of 12 pints) to 6 cups, it is clear that 24 cups is larger than 6 cups. Therefore, 12 pints is bigger than 6 cups.

I could really use some help right now. I have been trying to do this for a few hours and still can't seem to find the right answer. If someone could please help me out it would mean a lot to me.

EF is 1.98, AB is 16.23 and HI is 12.22

Step-by-step explanation:

Step 1:

In figure 1, given sin 26° = 0.44 and hypotenuse = 4.5. Use trigonometric ratio sin D to find EF.

sin 26° = EF/DF

⇒ 0.44 = EF/4.5

∴ EF = 0.44 × 4.5 = 1.98

Step 2:

In figure 2, given cos 52° = 0.616 and adjacent side (AC) = 10. Use trigonometric ratio cos A to find hypotenuse (AB).

cos 52° = AC/AB

⇒ 0.616 = 10/AB

∴ AB = 10/0.616 = 16.23

Step 3:

In figure 3, given tan 42° = 0.90 and opposite side (GH) = 11. Use trigonometric ratio tan I to find adjacent side (HI).

tan 42° = GH/HI

⇒ 0.90 = 11/HI

∴ HI = 11/0.90 = 12.22

Answer:

1) 1.98 units

2) 16.23 units

3) 12.22 units

Step-by-step explanation:

Q1) sin(26) = EF/ FD

0.44 = EF/4.5

EF = 4.5×0.44 = 1.98

Q2) cos(52) = AC/AB

0.616 = 10/AB

AB = 10/0.616

AB = 16.23

Q3) tan(42) = GH/HI

0.9 = 11/HI

HI = 11/0.9

HI = 12.22

How to solve ×+6y=13. 2×+y=15

Answers

Answer:

x, y = 7, 1

Step-by-step explanation:

x+6y=13 ............ (i)

2x+y=15 ........... (ii)

We will apply substitute method.

From equation (i), we can get,

x+6y=13

or, x = 13 - 6y .......... (iii)

Putting the value of x in equation (ii), we can get,

2x+y=15

or, 2 × (13 - 6y) + y = 15

or, 26 - 12 y + y = 15 [multiplying]

or, -11 y = 15 - 26 [Subtracting 26 from both the sides]

or, -11 y = -11

or, [(-11 y) ÷ (-11)] = [(-11) ÷ (-11)] [Dividing both the sides by -11]

or, y = 1

Therefore, the value of y = 1

Putting y = 1 in equation (iii), we get,

x = 13 - 6y

or, x = 13 - 6 × 1

or, x = 13 - 6

or, x = 7

Therefore, the value of x = 7.

Answer: x, y = 7, 1

A rose garden is going to be built in the city park in the shape of a parallelogram with a rectangular walkway through it. The garden region is shown below. There will not be roes in the walkway. Find the total area where roes will be planted. Show your work.

Answers

760 sq feet

Step-by-step explanation:

Step 1 :

The sides of the given parallelogram are 60 feet and 40 feet and the height is 38 feet

The length of the rectangular walkway = 38 ft

Width of the walkway = 20 ft

The roses are planted in the park (parallelogram) except in the walkways 's area ( rectangle)

Hence the total area where the roses are planted is the park 's area (parallelogram) - the walkway's area ( rectangle.)

Step 2 :

Area of the park (parallelogram ) = b * h = 40 * 38 = 1520 sq ft

Area of the walkway (rectangle) = l * b = 38 * 20 = 760 sq ft

Area of the park where roses will be planted = 1520 - 760 = 760 sq ft.

-4x+8y=20
2x+2y=-30

Answers

Answer:

x = -13 and y = -4

Step-by-step explanation:

-4x + 8y = 20 ................... eqn 1

2x + 2y = -30 ................... eqn 2

Step 1: Multiply eqn 1 by 2 and eqn 2 by 4

(-4x + 8y = 20) × 2

(2x + 2y = -30) × 4

we will have

-8x + 16y = 40 ....................eqn 3

8x + 4y = - 120 .................. eqn 4

Step 2: Add eqn 3 and 4 together

20y = - 80

Step 3: divide all through by 20

y = -80/20

y = -4

Step 4: Substitute -4 for y in eqn 1

-4x + 8(-4) = 20

-4x - 32 = 20

-4x = 20 + 32

-4x = 52

Step 5: Divide both sides by -4

x = 52/-4

x = -13

Answer:

 {x,y} = {-35/3,-10/3}

Step-by-step explanation:

 -4x+8y=20;2x+2-30  

System of Linear Equations entered :

  [1] -4x + 8y = 20

  [2] 2x + 2y = -30

Solve by Substitution :

// Solve equation [2] for the variable  y 

[2] 2y = -2x - 30

[2] y = -x - 15

// Plug this in for variable  y  in equation [1]

  [1] -4x + 8•(-x -15) = 20

  [1] -12x = 140

// Solve equation [1] for the variable  x 

  [1] 12x = - 140 

  [1] x = - 35/3 

// By now we know this much :

  x = -35/3

  y = -x-15

// Use the  x  value to solve for  y 

  y = -(-35/3)-15 = -10/3 

Solution :

 {x,y} = {-35/3,-10/3}

Find the distance between -2x + y = 6 and x = 1/2x - 4. Round your answer to the nearest tenth.
Please I need help and answer in a decimal

Answers

The distance between the two lines,-2x + y = 6 and x = 1/2x - 4, is approximately 4.5 units

Calculating the distance between two lines

To find the distance between two lines, we can use the formula:

Distance = |(Ax + By + C)| / sqrt(A^2 + B^2)

Where A, B, and C are the coefficients of the standard form equation of the first line

and x and y are the coordinates of a point on the second line.

Let's first convert the equations of the lines into the standard form (Ax + By + C = 0):

-2x + y - 6 = 0 --> 2x - y + 6 = 0 (Line 1)

x - 2x/2 - 4 = 0 --> -x + 4 = 0 --> x - 4 = 0 (Line 2)

Now, we can use the formula to find the distance between the two lines:

distance = |(Ax + By + C)| / sqrt(A^2 + B^2)

Let's take a point on Line 2, for example, (4,0). Then:

Distance = |(24 - 10 + 6)| / sqrt(2^2 + (-1)^2)

Distance = |10| / sqrt(4 + 1)

Distance = 10 / sqrt(5)

Distance = 4.472

Distance ≈ 4.5

Hence, the distance is approximately 4.5 units

Sorry mam I use mental math

Answer: X = —5 and Y = —2

Step-by-step explanation: What we have is a pair of simultaneous equations;

3X + Y = —17 —————-(1)

6X — 6Y = —18 ————(2)

We shall use the substitution method as instructed. Looking at equation (1),

We shall make Y the subject of the equation, hence

Y = —17 —3X

We shall now substitute for the value of Y into equation (2)

6X — 6Y = —18

6X — 6(—17 —3X) = —18

6X + 102 + 18X = —18

By collecting like terms we now have

24X = —18 —102

(Note that when a positive value crosses to the other side of the equation it becomes negative and vice versa)

24X = —120

Divide both sides of the equation by 24

X = —5

Having calculated the value of X as —5, we can now calculate Y as follows

From equation (1)

3X + Y = —17

3(—5) + Y = —17

—15 + Y = —17

Add 15 to both sides of the equation

—15 + 15 + Y = —17 + 15

Y = —2

Therefore, X = —5 and Y = —2

The IntNode constructor has been defined inline (within the class declaration). Do not write any other functions for the IntNode class. Use as is.struct IntNode {int data;IntNode *next;IntNode(int data) : data(data), next(0) {} };IntList class Encapsulated (Private) Data Fieldshead: IntNode *tail: IntNode *Public Interface (Public Member Functions)IntList(): Initializes an empty list.~IntList(): Deallocates all remaining dynamically allocated memory (all remaining IntNodes). void display() const: Displays to a single line all of the int values stored in the list, each separated by a space. This function does NOT output a newline or space at the end.void push_front(int value): Inserts a data value (within a new node) at the front end of the list.void pop_front(): Removes the value (actually removes the node that contains the value) at the front end of the list. Does nothing if the list is already empty.bool empty() const: Returns true if the list does not store any data values (does not have any nodes), otherwise returns false. main.cpp test harness for labUse this main.cpp file for testing your IntList:. #include using namespace std; #include "IntList.h" int main() {//tests constructor, destructor, push_front, pop_front, display { cout When its 75 kW (100 hp) engine is generating full power, a small single-engine airplane with mass 700 kg gains altitude at a rate of 2.5 m/s (150 m/min, or 500 ft/min).
