The quantity of paint will be 2 litres for 20 square meters area.
What is an expression?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.

in a class of 60 student, the number of student who passed biology is 6 more than the number who passed chemistry every student passed both at least one of the two subjects and 8 student passed both subject
Firstly we need to find how many students passed chemistry or biology
60-8=52 studdnts passed biology or chemistry
Let number of students who passed chemistry is x, than number of students who passed biology is 52-x.
[tex]52 - x - x = 6 \\ - 2x = - 46 \\ x = 23[/tex]
So, 23 students passed chemistry, than
23+6=29 students passed biology
Answer: 23 students passed chemistry and 29 students passed biology
Answer:

Choose all answers that apply:
A 33x-33=33x+25
B 33x+33=33x+25
C 33x+25=33x+25
D 33x-25=33x+25
Answer:
Brainliest Please
A, B, D
Step-by-step explanation:
Because if you subtract one of the constants from both sides then you should only have equal variables. In other words, both sides have to be identical in this situation.
33x-33= 33x + 25
33x = 33x + 58 No matter what you make x, the right will be 58 bigger than the right so there is no solution.
33x+33=33x+25
33x+8= 33x nope no solution
33x+25=33x+25
33x = 33x both sides identical so there is a solution
33x-25 = 33x +25
33x= 33x+50
A new phone costs $450. There is a 40% discount on the price of the phone and an 8% sales tax on the discount price. What is the final cost of the phone after the discount and the sales tax?
Answer:
291.60 is the final cost
Step-by-step explanation:
First find the cost of the phone before tax
Discount
450*.40
180
Price after discount
450-180
270
Now find the tax
270* 8%
270 *.08
21.60
Add this to the price after discount
270+21.60
291.60
Answer:
291.60
Step-by-step explanation:
40% of 450 is 270 and 8% of 270 is 21.6 so add 21.6 to 270 and you get 291.60

Find the 12th term of the geometric sequence 8, 16, 32, ...
Answer:
Step-by-step explanation:
\[a_{n}=a{1}r^{n-1}\]
r=16/8=2
a_{12}=8(2)^{12-1}
[tex]a_{12}=8(2)^{11}=16384[/tex]
The 12th term of the geometric sequence is 16384.
What are arithmetic and geometric sequence?An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference
d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.
In a geometric sequence numbers are written in the same common ratio(r).
It means every next number is a multiple of a common constant and the previous number.
r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.
Given, a geometric sequence 8, 16, 32,... which has a common ratio(r)
= 16/8 and first term a₁ = 8.
We know nth term of a geometric sequence is aₙ = a₁rⁿ⁻¹.
∴ 12t term of the geometric sequence is a₁₂ = 8.2¹²⁻¹
= 8.2¹¹.
= 8.2048.
= 16384.

Answer:
number five: 37.065 number six 241
Step-by-step explanation:
FOR NUMBER FIVE:
so for the rectangles, the formula is L * W. L for length W for width
so 5×3 = 15. and there are 2 rectangles with the same measurment so its
15 + 15 which is 30 (for both rectangles)
and for the circle formula its pi r^2 where pi is 3.14 and r is radius
so 3.14 × 3^2 = 28.26. but since its a quarter of a circle, divide it by four which is 7.065.
so 30 + 7.065 = 37.065
FOR NUMBER SIX:
the area of a triangle formula is b * h ÷ 2 where b is base and h is height
so its 22 * 8 / 2 = 88
and for the trapezoid the formula is [tex]\frac{a+b}{2} h[/tex] where a and b are the bases and h is height
so its[tex]\frac{12+22}{2} *9[/tex] = 153
88+153= 241

Which expression represents the area of the base of the cone? A cone with diameter 12 inches, height 8 inches, and slant height 10 inches. B = pi r squared (pi) (5 squared) (pi) (6 squared) (pi) (10 squared) (pi) (12 squared)
Answer: (pi) (6 squared)
Step-by-step explanation:
Hi, the base area of a cone is a circle, so, to answer this question we have to apply the next formula:
Area of a circle: (pi) radius^2
The diameter (d) of a circle is equal to: 2 radius
So:
D = 2r
Replacing with the value given:
12 =2r
12/2=r
radius= 6 inches
Back with the Area formula:
A = (pi) 6^2

An equilateral triangle has a side length of 7 cm. If a perpendicular is dropped from a corner, what is the length of the perpendicular?
Answer:
6.06cm
Step-by-step explanation:
An equilateral triangle is a triangle that has all its sides equal. If the given equilateral triangle has a side length of 7 cm, then all its sides are 7cm each. To get the length of the perpendicular dropped from a corner. we will use the Pythagoras theorem.
According to the theorem,
hyp² = opp²+adj²
Lets take the height as the opposite side of one of the right angled triangle as shown in the attachment.
hyp = 7cm and adj = 7/2 = 3.5cm
opp² = 7² - 3.5²
opp² = 49 - 12.25
Opp = √36.75
Opp = 6.06cm
This shows that the length of the perpendicular is 6.06m

What is the probability of landing on a 3 and then landing on a 2?
Simplify your answer and write it as a fraction or whole number.
Answer: 1/9
Step-by-step explanation:
You have 3 possible options. The probablility of the spinner landing on 3 is 1/3. The probability of it landing on 2 is also 1/3. For them to happen together, you multiply them. 1/3 * 1/3 = 1/9.
The probability of landing on a 3 and then landing on a 2 is,
⇒ 1/9
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one
Given that;
You spin the spinner twice.
Now, The probability of the spinner landing on 3 is,
⇒ 1/3.
And, The probability of it landing on 2 is,
⇒ 1/3.
Hence, The probability of landing on a 3 and then landing on a 2 is,
⇒ 1/3 × 1/3
⇒ 1/9.
