The quantity of paint will be 2 litres for 20 square meters area.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Gia is painting her wall. 1 litre of paint can cover 10 square meters. She has a rectangular wall that measures 4 meters by 5 meters.

The total area of the wall = 4 x 5 = 20 square meters

Paint for 10 square meters area = 1 litre

Paint for 20 square meters area =  1 x 2 = 2 liters

Therefore, the quantity of paint will be 2 litres for 20 square meters area.

Answer:

-$32

Step-by-step explanation:

Given that

Overdraft fee = $30

Preston Balance = $50

Total expenditure = $52

As per the given question the solution of new balance is provided below:-

To reach the new balance of Presont's first we need to find out the overdraft balance which is as follows:-

Overdraft balance = Balance - Total expenditure

= $50 - $52

= -$2

Since there is a balance of $50 but Pretson purchased for $52 value that results -$2 overdraft balance. In order to determine the new balance we simply added the overdraft fee and overdraft balance which is shown in negative sign.

Now according to the question the New balance of Presont's = Overdraft balance - overdraft fee

= -$2 - $30

= -$32

Answer:

$44,000

Step-by-step explanation:

The statement indicates that Sandra saves 9% of her salary and she saved $4,050 this year. That means that the 9% of her salary, x, is equal to $4,050. You can write the following:

x*0.09= 4,050

Now, you can isolate x to find her salary this year:

x=4,050/0.09= 45,000

Then, you have that this year salary was 1000 more than in her previous year. As you have found her salary for this year, you can subtract 1,000 from it to find her salary in the previous year:

45,000-1,000= 44,000

According to this, the answer is that her salary in the previous year was $44,000.

Answer:

64°

Step-by-step explanation:

Both triangles represent a right angle by the small box in the angle.

Right angles = 90°

Since the triangles are congruent, then they would have the same measurements in their angles an sides. All triangles also have a sum of 180°. So, we can just subtract (26 + 90) from 180 to get the third angle.

180 - (26 + 90)

180 - 116

64

So, the m∠KLM is 64°.

Answer:

Mae Ling earns a weekly salary of $335.

She also earns 5.0% commission on sales. If she sold 4200 worth of merchandise, she would get 4200 x 5/100 = 210$

Totally, she earns 335 + 210 = 545$

Hope this helps!

:)

Answer:

$545

Step-by-step explanation:

Commission is basically the percentage of the profit made that the salesperson gets to keep. The weekly salary is a fixed amount, so that won't change.

Here, Mae Ling sells $4200 worth of merch, which is the profit made, so the commission will be 5% of that:

5% * 4200

Remember that % is just "out of 100", so 5% = 5/100:

(5/100) * 4200 = $210

Add this to the salary:

335 + 210 = $545

She would make $545.

Remember that a rectangle is a quadrilateral which have its opposite sides equal and parallel, and all its internal angles are 90°. So, those are all the characteristics we need to demonstrate.

Additionally, the diagonals of a rectangle bisect each other.

Having said that, the choices A, C and D can help to demontrate that the figure is a rectangle.

You prove that abcd is a rectangle by the options A, Cand D.

We have given that figure ABCD

we have to determine that ABCD is a rectangle.

Remember that a rectangle is a quadrilateral which have its opposite sides equal and parallel, and all its internal angles are 90°.

So, those are all the characteristics we need to demonstrate.

A rectangle is a quadrilateral with four right angles. It can also be defined as an equiangular quadrilateral, since equiangular means that all of its angles are equal or a parallelogram containing a right angle. A rectangle with four sides of equal length is a square.

Additionally, the diagonals of a rectangle bisect each other.

Having said that, choices A, C, and D can help to demonstrate that the figure is a rectangle.

Let r represent cost of each box.

We have been given that Mia bought 10 boxes of brownies. So cost of 10 boxes would be [tex]10r[/tex].

We have been given that Mia bought 10 boxes of brownies at the store for a total of $64. The tax on the purchase was $5. So the total cost of 10 boxes would be cost of 10 boxes plus tax.

We can represent this information in an equation as:

[tex]10r=64+5[/tex]

We can subtract 64 from both sides as:

[tex]10r-64=64-64+5[/tex]

[tex]10r-64=5[/tex]

Therefore, our required equation is [tex]10r-64=5[/tex] and option 'c' is the correct choice.

2h = 12 ( divide both sides by 2 )

The point N lies inside the circle

Step-by-step explanation:

A circle is centered at the point T(-6,3) and has a radius of r=1.

To determine if the point N(3,-3) is inside or outside the circle, the distance between N and the point T must be lower than 11.

To calculate the distance between points T and N you use:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

where x1 and y1 are the coordinates of T, and x2 and y2 the coordinates of N.

[tex]d=\sqrt{(3-(-6))^2+(-3-3)^2}=\sqrt{9^2+6^2}=10.81[/tex]

d < 11

The distance d is lower than the radius of the circle. Hence, the point N lies inside the circle

So

Total money = 20

Entrance fee = 1.75

Food = 2.50

Ride = 1.05

Amount spend = 1.75 + 2.05 = 3.8

Left for rides = 20 - 3.8 = 16.2

So rides = 16.2 ÷ 1.05 = 15

I think atleast 15 rides
