Answer:

7f - 3

Step-by-step explanation:

We'll combine like terms to simplify this. Adding anything with an f (the variable) to anything else with an f, and adding just plain numbers to just plain numbers.

2f + 5 + 5f - 8

= 2f + 5f + 5 - 8

= 7f - 3

Answer:

$66.35

Step-by-step explanation:

To find this answer with y=mx+b, we should first explain what it is. Y is our output or answer. M is our variable and x is the slope of our variable or how often it occurs. B, is our y intercept, our initial starting amount. Knowing this, we must figure out y. To do this we must multiply his hourly wage by the hours he works which is $12.50x5. This will get us $62.50. Now that we know how much he makes hourly, we add his initial wage of $3.85 to get us $66.35

This means he will make $66.35 if he works a full 5 hour shift.

Answer:

1x+1y= 9

x= adults y= children 9= the amount they have to pay to play a game if its 1 adult and 1 child

The expression represents the total cost for adults and children:-

Ca = $3.75 + 5g

Cc = $2.50 + 4g

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that for adults, a bowling alley charges $3.75 for shoe rental and $5 per game. For children, the cost is $2.50 for shoe rental and $4 per game.

For adults the expression will be:-

Ca = $3.75 + 5g

For children, the expression will be:-

Cc = $2.50 + 4g

Hence, the expression are Ca = $3.75 + 5g and Cc = $2.50 + 4g.

Answer:

10 feet

Step-by-step explanation:

Perimeter of rectangle = 2l+2b

Area of the rectangle = l x b

Area of the rectangle = 4 square feet

possible factors of 4 = 2x2/4x1

So sides of the rectangle are 4 & 1 as 2&2 would make it a square

So perimeter= 2x4+2x1

= 8+2

= 10 feet

Answer:

x^2 - 9

Step-by-step explanation:

The square root of the quadratic equation [tex](x^2 -6x+ 9)[/tex] if x<-3 would be equal to (x-3).

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

The given quadratic equation is

[tex](x^2 -6x+ 9)[/tex]

We have to find the square root of the quadratic equation

[tex]\sqrt{(x^2 -6x+ 9)} \\\\\sqrt{(x^2 -3x-3x+ 9)} \\\\\sqrt{x(x-3)-3 (x-3)} \\\\\sqrt{(x-3) (x-3)} \\\\\sqrt{(x-3)^2} \\\\(x-3)[/tex]

Thus, the square root of the quadratic equation [tex](x^2 -6x+ 9)[/tex] if x<-3 would be equal to (x-3).

Answer:

1) yes  2) no  3) yes

Step-by-step explanation:

The lengths of the two shorter sides must be greater than the length of the longest side.

1) 8 + 9 > 10    yes

2) 1 + 1 = 2      no

3)  6 + 8 > 9    yes

The lengths which can be side of triangle are:

Apply the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

1. 8, 9, 10:

The sum of the lengths of the two smaller sides is 8 + 9 = 17 > 10

Therefore, these numbers can be the lengths of the sides of a triangle.

2. 1, 1, 2:

The sum of the lengths of the two smaller sides is 1 + 1 = 2.

No, 2 is equal to the length of the longest side.

So these numbers cannot be the lengths of the sides of a triangle.

3. 6, 9, 8:

The sum of the lengths of the two smaller sides is 6 + 8 = 14 > 10

Therefore, these numbers can be the lengths of the sides of a triangle.

Answer:

If D = 0, then the quadratic equation has 1 solution x = − b/2a

Step-by-step explanation:

If we have a quadratic equation x² +3x-4= 0

Then the corresponding values of a= 1, b=3, c= -4

Finding the discriminant gives

D=  b2 - 4ac.

D= 3²- 4(1) (-4)

D= 9 + 16

D= 25  

Here a> 0

But if a< 0  e.g a= -1

D=  b2 - 4ac.

D= 3²- 4(-1) (-4)

D= 9 - 16

D= -7  

Here a < 0 so we get the answer -7  < 0

D=  b2 - 4ac.

D= 4²- 4(-1) (-4)

D= 16 - 16

D= 0  

Here a< 0 and b= - c so that D= 0

When D < 0 roots do not exist.

If D = 0, then the quadratic equation has 1 solution x = − b/2a

This can be found out by using the quadratic formula

x= -b±√b²- 4ac/ 2a

But D= 0

x= -b±0/ 2a

x= -b/2a

Answer:

4(4)

Step-by-step explanation:

1.25 (4(4) - 10) = 7.5

1.25(16 - 10) = 7.5

1.25(6) = 7.5

1.25 + 1.25 = 2.5 + 2.5 = 5 + 2.5 = 7.5

   1    +   1   =  2   +   2  =  4  +  2  = 6    

An equation is formed of two equal expressions. The value of x that will make the given equation true is 4.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The value of x that makes the equation true can be found by finding the value of x in the given equation. Therefore, the value of x is,

1.25(4x - 10) = 7.5

Multiply 1.25 inside the parenthesis,

5x - 12.5 = 7.5

Add 12.5 on both sides of the equation,

5x - 12.5 + 12.5 = 7.5 + 12.5

5x = 20

Divide both sides of the equation by 5,

5x/5 = 20/5

x = 4

Hence, the value of x that will make the given equation true is 4.

Pyramid

Step-by-step explanation:

I think it's called a pyramid

Answer:

a) Lateral surface area = 1225.2 m²

b) Total surface area = 1756.2 m²

Step-by-step explanation:

We are to find the Lateral and Total surface area of the cone in the diagram

Slant height = l = 30m

Diameter = 26 m

Radius = Diameter /2 = 26m/2 = 13m

a) The Lateral surface area of a cone when given the slant height is calculated as:

πr × l

= π × 13 × 30

= π × 13 × 43

= 1225.2211349 m²

Approximately = 1225.2 m²

b) The Total Surface area of the cone when given the slant height is calculated as:

πr( r + l)

= π × 13 × (13 + 30)

= π × 13 × 43

= 1756.1502934 m²

Approximately = 1756.2 m²
