The inequality is (3,∞) < x < 4.

A declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to. An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. [1] The majority of the time, size comparisons between two numbers on the number line are made. Different types of inequalities are represented by a variety of notations, including:

The symbol a b indicates that an is smaller than b.

When a > b is used, it indicates that an is bigger than b.

The perimeter of the given rectangle is 16r-14s centimeters.

Let width be represented by=w

Let length be represented by=l

Let perimeter be represented by=p

Then,

l=(r-5s)centimeters (Given in the question)

while w=(7r-2s)centimeters (Given in the question)

The formula for the perimeter of a rectangle= 2(l+b)

where l is the length while b is the breadth of the rectangle.

On putting values in the equation:

p=2(l+b)

p=2(l+w)

p=2[(7r-2s)+(r-5s)]

on opening the bracket 2 is multiplied by both terms.

p=2(7r-2s)+2(r-5s)

p=(2x7r-2x2s)+(2xr-2x5s)

p=(14r-4s)+(2r-10s)

p=14r-4s+2r-10s

p=14r+2r-4s-10s

p=14r+2r-(4s+10s)

p=14r+2r-(14s)

p=16r-(14s)

Thus,

p=16r-14s centimeters

Jared bought 7 cans of paint. Let the number of red paint cans that Jared bought be x. The number of black paint cans he bought would be 7 - x. A can of red paint costs $3.75 and a can of black paint costs $2.75.

He spent $22 in all. Therefore we can write:3.75x + 2.75(7 - x) = 22 Multiplying out the second term and collecting like terms gives:0.5x + 19.25 = 22Subtracting 19.25 from both sides:0.5x = 2.75Dividing by 0.5:x = 5.5Since Jared can't buy half a can of paint, we should round the answer to the nearest integer. Hence, he bought 5 cans of red paint and 2 cans of black paint. The total cost of the 5 cans of red paint would be 5 x $3.75 = $18.75.The total cost of the 2 cans of black paint would be 2 x $2.75 = $5.50.The total cost of all 7 cans of paint would be $18.75 + $5.50 = $24.25.We spent more than Jared's budget. The value of $24.25 exceeds Jared's budget of $22. Hence, there is a problem with this problem statement.

Answer:

its the first one I think

Step-by-step explanation:

To compare the distances of 2 miles, 4,800 feet, and 4,400 yards, we need to convert all the distances to the same unit. Let's choose feet as the common unit.

1 mile = 5,280 feet (by definition)

2 miles = 10,560 feet (since 2 miles x 5,280 feet/mile = 10,560 feet)

1 yard = 3 feet (by definition)

4,400 yards = 4,400 x 3 feet/yard = 13,200 feet

Now that we have all distances in feet, we can order them from least to greatest:

2 miles = 10,560 feet

4,400 yards = 13,200 feet

4,800 feet = 4,800 feet

Therefore, the order from least to greatest is: 4,800 feet, 2 miles, 4,400 yards.

Note that it is always important to keep track of the units when comparing or combining quantities.

Answer:

a) 144π cm²

b) 248π cm²

Step-by-step explanation:

Using the formula, curved surface area of a cone = πrl where r = radius and l = slant height,

Curved surface area of large cone = π (10) (12 + 3) = π (10)(15) = 150π

Curved surface area of small cone = π(2)(3) = 6π

a) Curved surface area of frustum = 150π - 6π = 144π cm²

b)
The frustum has a top surface which is a circle of radius 2 and a bottom surface which is also a circle of radius 10

The area of a circle is πr²

So Total area of both circles = π(2)² + π(10)² = 4π + 100π = 104π

Total surface area of frustrum = 144π + 104π = 248π cm²

Answer:

y = -2x + 7

Step-by-step explanation:

to write the equation to this problem, we need to find the the y intercept, or the point where the line intersects the Y axis

a slope of -2 means that for every x unit in the positive x direction (right) two y units are moved in the negative Y direction (downward)

so if we subtract (go to the left) 1x that means we would also have to add (go up) 2y, which would leave us at the point (0,7)

now, an equation for a line is written as Y = MX + B

M = slope

B = y intercept

our slope, as we said before, is -2, and we found the Y intercept, 7, so now we can construct our equation

Answer: x=25

Step-by-step explanation:

Simplifying

(2x + -10) = (65 + -1x)

Reorder the terms:

(-10 + 2x) = (65 + -1x)

Remove parenthesis around (-10 + 2x)

-10 + 2x = (65 + -1x)

Remove parenthesis around (65 + -1x)

-10 + 2x = 65 + -1x

Solving

-10 + 2x = 65 + -1x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add 'x' to each side of the equation.

-10 + 2x + x = 65 + -1x + x

Combine like terms: 2x + x = 3x

-10 + 3x = 65 + -1x + x

Combine like terms: -1x + x = 0

-10 + 3x = 65 + 0

-10 + 3x = 65

Add '10' to each side of the equation.

-10 + 10 + 3x = 65 + 10

Combine like terms: -10 + 10 = 0

0 + 3x = 65 + 10

3x = 65 + 10

Combine like terms: 65 + 10 = 75

3x = 75

Divide each side by '3'.

x = 25

Simplifying

x = 25

The solution for p(-2) in the function when the function p(n) = 2n is -2

From the question, we have the following equation that can be used in our computation:

p(n)=2n

To make the equation legible, we need to rewrite it

So, we have the following representation

p(n) = 2n

Also from the question, we have

p(-1)

This means that the value of n is -1, and we calculate p(n) when n = -1

Substitute the known values in the above equation, so, we have the following representation

p(-1) =  2 * -1

So, we have the following equation

p(-1) =  2 * -1

There is no constant to add or subtract to both sides of the equation

So, we have the following representation

p(-1) =  -2

Hence, the solution is -2

Answer:

x = 42 degrees

y = 37 degrees

Step-by-step explanation:

Those are right angle triangles. So you know the right angles are 90 degrees, and each triangle gives you the measurement of another angle.

So, take the triangle in the top left (x):

180 - 90 - 48 = x

Same with the other triangle (y)

180 - 90 - 53 = y

the values of the vertically opposite angles ∠ RTS and ∠ PTQ will be 40° and ∠ PTR will be 140°.

We are given the value of two vertically opposite angles as:

∠ PTQ = x + 28

∠ RTS = 2 x + 16

We need to find the value of both the angles.

So, we get that:

x + 28 = 2 x + 16

2 x - x = 28 - 16

x = 12

Substituting it to find the values of the angles:

∠ PTQ = x + 28

∠ PTQ = 12 + 28

∠ PTQ = 40°

∠ RTS = 2 x + 16

∠ RTS = 2 (12) + 16

∠ RTS = 24 + 16

∠ RTS = 40°

∠ PTR = 180 - 40 = 140°

Therefore, the values of the vertically opposite angles ∠ RTS and ∠ PTQ will be 40° and ∠ PTR will be 140°.

Expanding brackets involves removing the brackets by multiplying each term in the brackets by every term outside of the brackets. The process of expansion is also known as the distributive law. When expanding brackets be very careful of negative numbers. 

Once a set of brackets has been expanded, it is possible for several like terms to appear. 

When this is the case you can use the box method or FOIL to ensure you expand the set of brackets properly. In general:
