4*(4*3)=48

The blanket is 4 feet wide and 12 feet long. The perimeter of the blanket is 32 feet and the area is 48 square feet.

The blanket is given to be 4 feet wide, and its length is 3 times its width, which means the length is 3 x 4 = 12 feet. Therefore, the blanket is 4 feet wide and 12 feet long.

For a rectangle, the formula for perimeter is 2*(length + width). Plugging in our values gives us 2*(12 + 4) = 32 feet.

The formula for the area of a rectangle is length * width. Using our dimensions, the area is 12 * 4 = 48 square feet.

Step-by-step explanation:

if 10=40%what about 100% which is total so you cross multiply and get your answer

There are a total of 25 students in Mr. Lee's class.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, There are 10 boys in Mr. Lee's class and 40% of the class are boys.

let, 'x' be the number of students in the class,

Therefore, 10 is 40% of 'x'.

(40/100)×x = 10.

0.4x = 10.

x = 10/0.4.

x = 25.

So, There are a total of 25 boys in the class.

To determine the clown's travel rate, divide the distance by time, resulting in a speed of 53 feet per second.

The student has asked how many feet per second the clown traveled if he was shot 212 feet into a net in 4 seconds. To find the rate of the clown's travel, we can use the formula for speed which is distance divided by time. So, we would take the total distance traveled, 212 feet, and divide it by the total time it took, which is 4 seconds.

The calculation would be:

Speed = Distance \/ Time

Speed = 212 feet \/ 4 seconds

Speed = 53 feet per second.

Therefore, the clown was traveling at a rate of 53 feet per second.

Answer:

Quadratic equations are actually used in everyday life, as when calculating areas, determining a product's profit or formulating the speed of an object. Quadratic equations refer to equations with at least one squared variable, with the most standard form being ax² + bx + c = 0.

Here is an example:

Antoine stands on a balcony and throws a ball to his dog, who is at ground level.

The ball's height (in meters above the ground), xxx seconds after Antoine threw it, is modeled by:

h(x)=-2x^2+4x+16h(x)=−2x

+4x+16h, left parenthesis, x, right parenthesis, equals, minus, 2, x, squared, plus, 4, x, plus, 16

What is the height of the ball at the time it is thrown?

here is another example:

Hope that was helpful.Thank you!!!

Answer:

see below

Step-by-step explanation:

Often, the simplest way to solve "ax2 + bx + c = 0" for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it doesn't factor at all, or you just don't feel like factoring. While factoring may not always be successful, the Quadratic Formula can always find the solution.

The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.

The Quadratic Formula is derived from the process of completing the square, and is formally stated as:

The Quadratic Formula: For ax2 + bx + c = 0, the values of x which are the solutions of the equation are given by:

Answer:

Phil is 16 inches tall and his shadow is 8 inches tall

Step-by-step explanation:

this is an algebra word problem.

1. Find the unknown and label it x.

Let Phil's shadow be x inches.

2. find other unknown quantities and define them with

Phil's height= 2x (phil is shadow is half as long as Phil is tall)

3. FInd the equation

if he was 4 inches taller (2x+4)

and his shadow was three inches shorter (x-3)

his height ( 2x+4) times the shadow's height (x-3) would be 100 square inches.

(2x+4) ×(x-3)=100

(2x+4)(x-3)=100

this is a quadratic equation and there are a number of ways to solve these. the two main ways are

1. quadratic equation

2. expanding and factorising

3. graphing

we will use 2. expanding and factorising for this problem. We need to make the right hand side = 0 by first factorising then rearranging.

(2x*x)+(2x*-3)+(x*4) +(4*-3)=100

2x^2 -6x+4x-3x-12=100

2x^2 -2x=112

2x^2 -2x-112=0

once factorised take out the common factor of 2

2(x^2-x-56)=0

now factorise what's in the brackets ( two numbers multiply to make 56 but add to make -1.

2(x-8)(x+7)=0

x-8=0 =>   x=8

x+7=0        x=-7 not possible

the shadow is 8 inces long. Phil is 16 inches tall.

Hope this is of help :)

Phil's height is 16 inches, and the length of his shadow is 8 inches.

To solve the problem, we will let Phil's height be denoted by h (in inches) and the length of his shadow be s (in inches).

1. Phil's shadow is half as long as Phil is tall.

2. If Phil were 4 inches taller and his shadow were 3 inches shorter, the product of his height and his shadow's length would be 100 square inches.

From the first condition:

[tex]\[ s = \frac{h}{2} \][/tex]

From the second condition, we can write the equation involving the modified height and shadow:

[tex]\[ (h + 4) \times (s - 3) = 100 \][/tex]

Next, substitute [tex]\( s = \frac{h}{2} \)[/tex] into the equation:

[tex]\[ (h + 4) \times \left(\frac{h}{2} - 3\right) = 100 \][/tex]

Simplify inside the parentheses:

[tex]\[ (h + 4) \left(\frac{h - 6}{2}\right) = 100 \][/tex]

Multiply both sides by 2 to eliminate the fraction:

[tex]\[ 2(h + 4) \left(\frac{h - 6}{2}\right) = 2 \times 100 \][/tex]

[tex]\[ (h + 4)(h - 6) = 200 \][/tex]

Expand the left-hand side:

[tex]\[ h^2 - 6h + 4h - 24 = 200 \][/tex]

[tex]\[ h^2 - 2h - 24 = 200 \][/tex]

Move 200 to the left side to set the equation to zero:

[tex]\[ h^2 - 2h - 224 = 0 \][/tex]

Now, we solve the quadratic equation using the quadratic formula [tex]\( h = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \) where \( a = 1 \), \( b = -2 \), and \( c = -224 \):[/tex]

[tex]\[ h = \frac{-(-2) \pm \sqrt{(-2)^2 - 4(1)(-224)}}{2(1)} \][/tex]

[tex]\[ h = \frac{2 \pm \sqrt{4 + 896}}{2} \][/tex]

[tex]\[ h = \frac{2 \pm \sqrt{900}}{2} \][/tex]

[tex]\[ h = \frac{2 \pm 30}{2} \][/tex]

This gives us two potential solutions:

[tex]\[ h = \frac{32}{2} = 16 \][/tex]

[tex]\[ h = \frac{-28}{2} = -14 \][/tex]

Since height cannot be negative, we discard ( h = -14 ).

Thus, Phil's height is:[tex]\[ h = 16 \text{ inches} \][/tex]

Using [tex]\( s = \frac{h}{2} \)[/tex]:

[tex]\[ s = \frac{16}{2} = 8 \text{ inches} \][/tex]

Answer:

x=-2

Step-by-step explanation:

1. Convert base

(1/64) to (4^-3)

2.Apply exponent rule

4^-3(2x+10)

3. 4x-10=-3(2x+10)

4.Expand

4x-10=-6x-30

4x-10+10=-6x-30+10 (add 10 to both sides)

4x=-6x-20 (simplify)

4x+6x=-6x-20+6x (add 6 to both sides)

5. 10x=-20 (divide both side by 10)

6. Then you get x= -2.

At the given rate, it would take 1.2 hours to fill the tank described.

To find out how many hours it will take to fill the water tank, we need to calculate the volume of the tank and then determine the time it takes to fill it at a rate of 10 gallons per minute.

The volume of the tank can be calculated using the formula for the volume of a rectangular prism.

Volume = 6 feet x 4 feet x 4 feet = 96 cubic feet

Convert this volume to gallons, knowing that 1 cubic foot is about 7.5 gallons:

So, the tank has a capacity of approximately 720 gallons.

To find the time it takes to fill the tank at a rate of 10 gallons per minute:

Time (minutes) = Volume (gallons) / Rate (gallons per minute)

Time (minutes) = 720 gallons / 10 gallons per minute = 72 minutes

Now, to convert this to hours, divide by 60 (since there are 60 minutes in an hour):

Time (hours) = 72 minutes / 60 minutes per hour ≈ 1.2 hours

Rounded to the nearest tenth, it will take about 1.2 hours to fill the water tank.

To determine the time to fill the tank, calculate the tank volume in cubic feet, convert that to gallons, and then divide by the rate of water flow and 60 to get the time in hours.

To determine how long it will take to fill the tank, we first need to calculate the volume of the tank in cubic feet. The tank is shaped like a cylinder, so the volume V of a cylinder is given by V = πr²h, where r is the radius and h is the height. In this case, the tank has a radius of 3 feet (half of the 6 feet diameter) and a height of 4 feet, so V = π(3)²(4) = π(9)(4) = 36π cubic feet.

Next, we need to consider that 1 cubic foot is equivalent to 7.5 gallons of water. Therefore, the tank capacity in gallons is 36π * 7.5.

We are told the tank is being filled at a rate of 10 gallons per minute. To determine how long it will take to fill the tank, we divide the total number of gallons the tank holds by the rate at which the tank is being filled. This will give the total time in minutes. To convert this time to hours, we then divide by 60, as there are 60 minutes in an hour.

So, the number of hours to fill the tank is (36π * 7.5) / 10 / 60, rounded to the nearest tenth.
