I got it right

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Answer:

E = 12.20(h) - 7.15

h = 6.82 hours

Given:

Pay hour = $12.20 per hour

Bus fare = $7.15

1.Equation:

Assume

She has work for "h" hours

Total earning = E

So,

E = 12.20(h) - 7.15

If,

Total earning = E = $90.45

So,

E = 12.20(h) - 7.15

90.45 = 12.20(h) - 7.15

h = 6.82 hours

Answer:

C

Step-by-step explanation:

Te unoccupied volume (V) of the cube is calculated as

V = volume of cube - volume of sphere

   = 7³ - [tex]\frac{4}{3}[/tex] πr³ ( r is the radius and r = 7 ÷ 2 = 3.5 )

   = 343 - [tex]\frac{4}{3}[/tex] π × 3,5³

   = 343 - [tex]\frac{4}{3}[/tex] π × 42.875

   = 343 - 179.59438

   = 163.4....

Answer:

Total cost of footpath = 528 m²

Step-by-step explanation:

Width of footpath is 2m.

Thus,

For longer footpath, there will be two sides. Thus; area = 2(24 + 2 + 2) × 2 = 112 m²

For shorter footpath, since the 2 longer sides have been taken care of, length remains 16m. Then area = 2(16 × 2) = 64 m²

Total area = 112 + 64 = 176 m²

cost to tile foot path is $3 per square metres.

Total cost of footpath = 176 × 3

Total cost of footpath = 528 m²

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:

1)6

2)20

3)45

Step-by-step explanation:

a=1/2 bh

1) 4*3=12/2=6

2) 8*5=40/2=20

3)15*6=90/2=45

Answer:

1) 6

2) 20

3) 45

Step-by-step explanation:

To find the area of a triangle, use the formula [tex]\frac{1}{2} bh[/tex], where [tex]b[/tex] represents the length of the base, and [tex]h[/tex] represents the height. In the first triangle, the base length is 4 and the height is 3, so the area is 6. In the second triangle, the base length is 5 and the height is 8, so the area is 20. In the third triangle, the base length is 15 and the height is 6, so the area is 45.

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:

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.
