If we plug in the known information into the formula, we will get the answer.

d=2.75 ind=2.75in

We know radius is half of d, so r=0.5*2.75=1.375 inr=0.5∗2.75=1.375in

The height is given as 4 in.

Pluggin all of these in the original formula gives us:

V=\frac{1}{3} \pi (1.375)^{2} (4)=7.919 cubic inchesV=

The Correct choice is :

D. Both ll and lll

[tex] \sf{ \red{ \underline{Solution - }}} \\ [/tex]

Given equation is 1/(x+2) - 1/(x-2) = 1

=> [(x-2)-(x+2)]/(x+2)(x-2) = 1

=> (x-2-x-2)/(x²-4) = 1

=> (-2-2)/(x²-4) = 1

=> -4/(x²-4) = 1

=> x²-4 = -4

=> x²-4+4 = 0

=> x² +0 = 0

=> x² = 0

The standard form is x² = 0 or x²+0x+0 = 0

Here I have used this formulae in your all questions.

The standard quadratic equation is ax²+bx+c = 0

Answer:

72

Step-by-step explanation:

We will first have to find the fraction of the whole land goats use. If we add 2/5 and 1/4, we will get 13/20. Simplifying the expression 1-13/20 gets 7/20, which is the total fraction of land the goat and sheep has. The goat will then get 7/20*1/7 of the whole land, which is 1/20. The sheep will then get 7/20*6/7 of the entire land, which is 3/10. Because 1/20 of the whole land is 12 acres, the farmer has 240 acres. SImplifying the expression 240*3/10 gets 72 acres

Answer:

C ) 1/3

Step-by-step explanation:

In the given equation, y = 1/3x, where it represents a proportional relationship:

1/3 represents the constant of proportionality which shows that as x increases, y also increases at the same rate. The constant of proportionality in this given instance is also the rate of change, or the slope.

The constant of proportionality under the direct proportion condition is the slope of the line when plotted for two proportional constants x and y on a graph.

Therefore, the correct answer is C) 1/3.

Answer:

b1= 2A/h - b2

Step-by-step explanation:

You have to multiply each side by 2, then divide each side by h. after that you subtract b1 from both sides and then you will get your answer.

Answer:

b1 = 2A / h - b2

Step-by-step explanation:

A = h(b1 + b2) / 2

[cross multiply]

h(b1 + b2) = A × 2

b1h + b2h = 2A

[divide both sides of the equation by h]

b1h / h + b2h / h = 2A / h

b1 + b2 = 2A / h

[make b1 the subject of the formula]

b1 = 2A / h - b2

a) x + y = 421

b) 2x + 5y = 1,244

a) x = 421 - y

b) 2 (421 - y) + 5y = 1,244 (substitution)

842 - 2y + 5y = 1244

Answer:

C

Step-by-step explanation:

Can't be B or D because the slope is negative but B and D have positive slopes. It's not A because slope is y2-y1/x2-x1. Take points (0,8) and (6,5) to plug into equation.

5-8/6-0= -3/6=-1/2

Therefore the answer is C since the y-intercept is 8 and the slope is -1/2

Let the height of rectangle be = x,

Area of rectangle = base × height

so, there are two cases now,

Case - 1 :

here, value of x (length) is negative, measure of length can't be negative, so length is not equal to -4/3

Case - 2 :

here, value of x = 4, and satisfys the condition so

The rectangle's height is 4 inches and the rectangle's base is also 4 inches.

Let's assume the height of the rectangle is 'h' inches.

According to the given information, the base of the rectangle is 8 inches shorter than three times its height. This can be expressed as:

Base = 3h - 8

The area of a rectangle is given by the formula:

Area = Length * Width

In this case, the area is given as 16 square inches. We can set up the following equation:

16 = h * (3h - 8)

Expanding the equation:

[tex]16 = 3h^2 - 8h[/tex]

Setting the equation equal to zero:

[tex]3h^2 - 8h - 16 = 0[/tex]

To solve this quadratic equation, we can use factoring, completing the square, or the quadratic formula. Let's solve it using the quadratic formula:

[tex]h = (-b \± \sqrt{b^2 - 4ac}) / (2a)[/tex]

For this equation, a = 3, b = -8, and c = -16. Plugging in the values:

[tex]h = (-(-8) \± \sqrt{(-8)^2 - 4 * 3 * (-16)}) / (2 * 3)\\\\h = (8 \± \sqrt{64 + 192}) / 6\\\\h = (8 \± \sqrt{256}) / 6\\\\h = (8 \± 16) / 6[/tex]

We have two possible values for h:

h₁ = (8 + 16) / 6 = 4

h₂ = (8 - 16) / 6 = -1

Since the height of a rectangle cannot be negative, we can discard the value h₂ = -1.

Therefore, the rectangle's height is 4 inches.

Now, we can find the base of the rectangle:

Base = 3h - 8

Base = 3 * 4 - 8

Base = 12 - 8

Base = 4

Therefore, the rectangle's base is also 4 inches.

Answer:

A candy bar costs $0.80

A bag of chips costs $6.20

Step-by-step explanation:

Let's call candy bars x, and bags of chips y.

Ruben ought 2x and 4y for $24

Lucis bought 2x and 2y for $14

This means that 2x+4y = 24 and 2x+2y = 14

Now we have a system of equations that we can solve.

2x + 2y = 14

2(x + y) = 14

x + y = 7

y = 7 - x

Plug this into the next equation to get:

2x + 4y = 24

2x + 4(7 - x) = 24

2x + 28 - 7x = 24

28 - 5x = 24

-5x = -4

x = -4/-5

x = 4/5 = 0.8

plug that x value into y = 7 - x to find y

y = 7 - x

y = 7 - (4/5)

y = 245/35 - 28/35

y = 217/35 = 6.2

now we can check our work:

2(x + y) = 14

2(6.2 + 0.8) = 14

2(7) = 14

14 = 14

^ this means our values are correct

Answer:

A candy bar costs $0.80

A bag of chips costs $6.20

Answer: 360

Step-by-step explanation:

If you double 18 and then multiply by 10 will be 360.

It is also known as the product. If the object n is given to m times then we just simply multiply them.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The expression is given below.

⇒ 18 x 20

The product of the numbers 18 and 20 will be 360.

If you double 18 and multiply the number by 10 will be

2(18) x 10 = 36 x 10 = 360

If you double 18 and then multiply by 10 will be 360.
