Answer:

Micah’s solution is wrong. The value of x=3 or -7/3

Step-by-step explanation:

First solve for the value of x

Given (1 – 3x) = 4(– + 2)

This can mean;  (1 – 3x) = 4(+ 2) or  (1 – 3x) = 4(-2)

In the first option (1 – 3x) = 4(+ 2) the value of x is ;

1 – 3x = 4(+ 2).....................open bracket

1-3x= 8...............................collect like terms

-3x=8-1

-3x=7....................................divide both sides by 3

x= -7/3  

In the second option

(1 – 3x) = 4(-2)

1-3x= -8

-3x= -8-1

-3x = -9

x= 3

Solutions  x= 3 0r -7/3

The values of x that make the statement true are 3 and -7/3

Answer:

Micah’s solution is wrong. There are no values of x that make the statement true.

Answer:

1. 15in^2

2. 3421.19in^3

3. 11494.04cm^3

4. Radius is 3.1

Hope this helps!

Step-by-step explanation:

The area of the base of first cylinder is 47.05 in², volume of a cone is 3421.2 in³, the  volume of a sphere is 11494.04 cm³ and the radius of last sphere is 3.102 cm.

Volume of cylinder is the amount of quantity, which is obtained by it in the 3 dimensional space.

Volume of cylinder can be given as,

V=πr²h

Here, (r) is the radius of the base of the cylinder and (h) is the height of the cylinder.

The area of the base of a cylinder with a volume of 240π in³ and a height of 16 inches has to be find out. The radius of this cylinder is,

V=πr²h

240π=πr²(16)

r=√(240/16)

r=3.87 in

Thus, the surface area of the base is

A=πr²

A=π(3.87)²

A=47.05 in²

The volume of a cone with a height of 27 inches and a radius of 11 inches is,

V=(πr²h)/3

V=(π(11)²(27))/3

V=3421.2 in³

The volume of a sphere with a radius of 14 cm is;

V=(4πr³)/3

V=(4π(14)³)/3

V=11494.04 cm³

The volume of a sphere is 125 π cm³. The radius of it is,

V=(4πr³)/3

125=(4πr³)/3

r=∛(93.75/π)

r=3.102 cm.

Thus, the area of the base of first cylinder is 47.05 in², volume of a cone is 3421.2 in³, the  volume of a sphere is 11494.04 cm³ and the radius of last sphere is 3.102 cm.

Step-by-step explanation:

If a ≤ b ≤ c is the length of the sides, then a + b > c.

(a)

We have a = 3cm, b = 4cm, c = 6cm.

Check:

a + b = 3cm + 4cm = 7cm

c = 6cm

7cm > 6cm → a + b > c   CORRECT :)

YES. It's possible.

(b)

We have a = 1cm, b = 3cm, c = 4cm

Check:

a + b = 1cm + 3cm = 4cm

c = 4cm

4cm = 4cm → a + b = c

NO. It's impossible.

Answer:

60 degrees

Step-by-step explanation:

Since all sides of the triangle are congruent and the angles of a triangle add to 180 degrees, divide 180 by 3 sides and you get 60 degrees.

Answer:

60°

Step-by-step explanation:

Since the sides have all got the "equal" sign, all the angles must be the same.

Angles in a triangle add up to 180°.

From this, we can set up an equation ⇔ y + y + y = 180°

⇒ y + y + y = 180°

( Simplify )

⇒ 3 y = 180°

( Divide both sides by 3 to isolate y )

y = 60°

Answer:

After how many seconds does it explode? 4 sec

At what height does it explode? 256ft

Step-by-step explanation:

The question simply asks us to find the vertex of the parabola mentioned.

Given equation : h = -16t² + 128t

Lets break this down. The equation is in its standard form : ax² + bx + c

Hence,

a = -16

b = 128

c = 0

Find the vertex when a standard form is given:

( -b/2a , f(-b/2a) )

(-128/-32, f( -128/-32 ))

(4,f( 4 ))

f(4) = -16(4)² + 128(4)

f(4) = -256 + 512

f(4) = 256

Vertex = (4,256)

.47 is 10.4% of 4.53

Option A,-10.4% is the rate of change of stock XYZ for this particular week.

How to find percentage change?

Step 1: Calculate the change (subtract old value from the new value)

Step 2: Divide that change by the old value (you will get a decimal number)

Step 3: Convert that to a percentage (by multiplying by 100 and adding a "%" sign)

Note: when the new value is greater then the old value, it is a percentage increase, otherwise it is a decrease.

Finding percentage change

We have given,On Monday, stock XYZ opened at $4.53 which is the initial value or old value

On Friday, it closed at $4.06,which will be final value or new value.

First calculate, difference between the two value using,

Explanation:

We are given that the original number of charms that Rosie has is c

We know that Ray gave Rosie 3 new charms

This means that the number of charms that Rosie originally had increased by 3

To express this increase, we use addition where we add 3 to the original number of charms that she had

New number of charms = original number of charms + 3

New number of charms = c + 3

the ones digit is 5, and the tens digit is 5 - 2, which is 3. So the 2-digit number is 35.

The question requires us to find a 2-digit number where the tens digit is two less than the ones digit and the sum of the digits is 8. To figure this out, let's call the ones digit 'x'. Since the tens digit is two less than the ones digit, the tens digit would be 'x - 2'. The sum of these two digits equals 8, so we can write the equation:

x + (x - 2) = 8

Solving for x gives us:

2x - 2 = 8

2x = 8 + 2

2x = 10

x = 10 / 2

x = 5

Therefore, the ones digit is 5, and the tens digit is 5 - 2, which is 3. So the 2-digit number is 35.

The probability of drawing the coin labeled '1' from a bag containing coins labeled '1', '2', and '3' is 1/3, or roughly 0.333. This represents a 33.3% chance.

The question is asking you to calculate the probability of drawing the coin labeled '1' in one draw from a bag of three coins, each labeled '1', '2', or '3'. In probability, we define an event's likelihood as the number of ways that event can occur divided by the total number of possible outcomes.

Here, the event we're interested in is picking the coin labeled '1'. Since there is only one coin labeled '1', there is just one way this event can occur. The total number of possible outcomes is defined by the number of coins in the bag, which is 3 – the coins labeled '1', '2', and '3'.

Therefore, the probability of drawing the coin labeled '1' is calculated as 1/3, or roughly 0.333 when rounded to three decimal places. That means there is approximately a 33.3% chance that the coin labeled '1' will be the next drawn from the bag.

3 times a number is 4 less than the square of that number. The negative solution is  -1

What are quadratic equations?

Quadratic equations are of the form ax² + bx + c where a ≠ 0.

Factorization, often known as factoring, is the process of expressing a number or another mathematical object or mathematical equations as a product of several factors.

Now, In the given question let's first assume that the unknown number is a variable x.

So, 3 times that number is (3 × x)

And then, 4 less than the square of that number is (x² - 4)

Now, as the question states that 3 times a number is 4 less than the square of that number,

So we can write,

3x = x² - 4

Now, we have to solve this quadratic equation with the help of factorization.

To solve the quadratic equation we first bring all the terms to any of the sides and after rearranging a little the equation is as follows:

x² - 3x - 4 = 0

Now, if we want to find the factors in the form ax² + bx + c we need to multiply a and c and then we have to identify what two numbers sum up to b and multiply to ac.

Here, a = 1, b = -3 and c = -4

Now, ac = -4

So, we have to identify what two numbers sum up to b and multiply to ac. The numbers are -4 and 1 and we can check that they sum up to -3 and multiply to -4.

So first we have to split the equation: x² - 3x - 4 = 0

x² - 4x + 1x - 4 = 0

Now, we have to group the above equation,

(x² - 4x) + (1x - 4) = 0

Taking x common from the first group and taking 1 common from the second group we get,

(x)(x - 4) + (1)(x - 4) = 0

Now, again taking (x - 4) common from the equation we get,

(x - 4) × (x + 1) = 0

So, we set each factor to zero now,

(x - 4) = 0

Adding 4 to each side of the equation we get,

x - 4 + 4 = 4

Simplifying we get,

x = 4

(x + 1) = 0

Adding -1 to each side of the equation we get,

x + 1 - 1 = -1

Simplifying we get,

x = -1

So, we now have two solutions of x that is 4 and -1

But according to the question we only need the negative one.

Therefore, the negative solution is  -1

The paddle wheel takes approximately 967 seconds to complete 100 full revolutions.

To calculate the time it takes for the paddle wheel to complete 100 full revolutions, we need to determine the distance traveled by the fins and divide it by their speed. The diameter of the paddle wheel is given as 4 feet, so the radius is half the diameter, or 2 feet. The distance traveled by one fin along the outer edge is equal to the circumference of a circle, which is 2π times the radius. In this case, the distance is 2π * 2 feet, or approximately 12.57 feet.

Since we want to find the time it takes for 100 full revolutions, we need to multiply the distance traveled by one fin by 100. So the total distance is 12.57 feet * 100, which equals 1257 feet.

Now we can divide the total distance by the speed of the fins to find the time it takes. The speed is given as 1.3 feet per second, so the time is 1257 feet divided by 1.3 feet per second, which is approximately 967 seconds. Rounding to the nearest second, it takes the paddle wheel approximately 967 seconds to complete 100 full revolutions.

The paddle wheel takes approximately 392 seconds to complete 100 full revolutions.

To find the time it takes for the paddle wheel to complete 100 full revolutions, we need to calculate the circumference of the wheel and divide it by the speed at the outer edge.

The circumference of the wheel is the diameter (4 feet) times π. So, the circumference is 4π feet.

Dividing the circumference by the speed of the fins (1.3 feet per second) gives us the time it takes for one revolution. To find the time for 100 revolutions, we multiply this time by 100 and round to the nearest second.

Therefore, the paddle wheel takes approximately 392 seconds to complete 100 full revolutions.
