Answer: 12
Step-by-step explanation:
Following PEMDAS, I’ll solve the multiplication first and then add or subtract the values from left to right.
1-2+5-2+5x2
1-2+5-2+10
-1+5-2+10
4-2+10
2+10
12
Answer:
12
Step-by-step explanation:
You need to use the order of operations, PEMDAS. It stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
First, multiplication on 5x2 so now it is 1-2+5-2+10.
Next, is addition and subtraction. When it says left to right you are starting with the part of the equation closest to the left, so 1-2=-1. Then add five to get 4. Subtract 2 to get 2. Finally, add 10 to get 12.
Hope you get an A! <3

The product of the polynomial is x² - x + xy + 16y - 2y² - 30
Polynomial
Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.
Polynomials are classified based on degree as linear, quadratic, cubic and so on.
Given the polynomial:
(x + 2y - 6)(x - y + 5) = x² + 2xy - 6x - xy - 2y² + 6y + 5x + 10y - 30
= x² - x + xy + 16y - 2y² - 30

The diameter of a circle field is 40m and that of another 96m . find the diameter of the circular field whose area is equal to the sum of the area of two fields
Answer :
According to the Question
Diameter of a circle field is 40m and that of another 96m .
We have to find the diameter of the circle whose area is equal to the sum of the area of given two circular fields.
Radius of field whose diameter is 40 m
→ r = 40/2 = 20m
Radius of field whose diameter is 96 m
→ r' = 96/2 = 48m
Now, calculating the diameter of Larger circular field.
Let the radius of larger field be R m .
Now, according to the given statement
Sum of Area of given two circular fields = Area of larger field
➠ πr² + πr'² = πR²
➠ π ( r² + r'²) = π R²
➠ 20² + 48² = R²
➠ 400 + 2304 = R²
➠ 2704 = R²
➠ √2704 = R
➠ 52 = R
Therefore, Diameter = 2 × R = 2×52 = 104 m
So, the diameter of Larger circular field is 104 m .
Answer:
Diameter of the circular field=40 m[tex]r = \displaystyle{ \frac{40 \: m}{2}} [/tex][tex]r=20 m[/tex]Diameter of another circular field=[tex]96 m[/tex]r=[tex]\displaystyle{\frac{96 m}{2}}[/tex]r=48 mArea of circular field(2)=[tex]πr^2[/tex]

=[tex]400π[/tex]
Area of circular field(2)=[tex]πr^2[/tex]
=[tex]π×(48)^2[/tex]
=[tex]2304π[/tex]
The sum of the area of the two fields=[tex]400π+2304π[/tex]=[tex]2704π[/tex]Let the radius of circular field that is formed so be r meter(m).
Now,
[tex] \cancel\pi {r}^{2} = 2704 \cancel\pi[/tex]

The time,
T
(seconds), it takes for a pot of water to boil is proportional to the amount,
A
(litres), of water.
It takes 210 seconds to boil 2.5 litres of water.
Work out how long it takes (to the nearest second) to boil 2.8 litres
Answer:
2.5 liters = 2500 grams
210 ÷ 2500 = 0.084
2.8 liters = 2800 grams
2800-2500 = 300
300×0.084 = 25.2
25.2 + 210 = 235.2 to boil 2.8 liters

In a camp ,there is enough flour for 300 persons for 42 days.How long will the flour last if 20 more persons join the camp
Answer/Step-by-step explanation:
Direct proportion: If a variable increases then other variable also increases with a constant factor i.e. y = kx
Inverse proportion: if a variable increases then other variable decreases with a constant factor i.e xy = k
Assume that food will last for d days if 20 more persons join the camp.
Understand the fact that for given food number of days food last is inversely proportional to the number of persons hence product of days food lasts and number of persons is constant,
Days x number of persons = constant
Equate the product of 300 persons and 42 days with (300 + 20) person and d days to solve for d.
[tex](300+20) *d=300*42[/tex]
⇒ [tex]d = \frac{12600}{320}[/tex]
⇒ [tex]d =\frac{1260}{32}[/tex]
⇒ [tex]d=\frac{315}{8}[/tex]
⇒ [tex]d=39.375[/tex] [tex]days[/tex] [tex]or[/tex] [tex]39(\frac{3}{8} )days[/tex] [tex]in[/tex] [tex]fraction[/tex]
Hence, if 20 more people Join (320 people ) it will last 39.375 days in decimal or 39 3/8 days in fraction

Answer:
Step-by-step explanation:
Answer:
The volume of the box is 56 cm ^3
The surface area or the amount of cardboard used is 100 cm ^3
Step-by-step explanation:
for the volume you multiply the top the side and the bottom of the box together 7*4*2=56 ^3
For the amount of cardboard used we have to find the area of all the sides then add them together. 7*4=28 28*2=56. we multiply it by 2 because there is 2 sides with the same measurements for each side.
2*4=8 8*2=16
2*7=14 14*2=28

What is the sum of the given polynomials in standard form? (x2 – 3x) (–2x2 5x – 3).
Sum of standard form polynomials means adding the terms of same variable. The sum of the given polynomial in standard form is,
[tex]-x^2+2x-3[/tex]
What is polynomial equation?A polynomial equation is the equation in which the unknown variable is one and the highest power of the unknown variable is n.
Here, n is any real number.
In the polynomial equation the the terms are added or subtracted from each other only when the power of the variable is same.
Given information-
The first polynomial equations given in the problem is,
[tex](x^2 - 3x)[/tex]
The second polynomial equations given in the problem is,
[tex](-2x^2+ 5x - 3).[/tex]
To find the sum of these two polynomials, add the two terms together as,
[tex](x^2 - 3x)+(-2x^2+ 5x - 3)[/tex]
Let the result of the sum is [tex]f(x)[/tex]. Thus,
[tex]f(x)=(x^2 - 3x)+(-2x^2+ 5x - 3)\\f(x)=x^2-3x-2x^2+5x-3[/tex]
Separate the similar power variable as,
[tex]f(x)=(x^2-2x^2)+(-3x+5x)-3\\f(x)=-x^2+2x-3[/tex]
Thus the sum of the given polynomial in standard form is,

Which conclusion can best be made from this scatter plot?
According to the graph, it can be inferred that the most accurate conclusion is that the older the age, the percentage of 3 points is lower (option c).
What does the graph show?The graph shows the relationship between the percentage of 3 points and different ages from 20 years to 50 years. In general, from twenty to 35 are the most points that refer to the percentage of 3 points.
What conclusion can be obtained?According to the graph, it can be inferred that the most appropriate conclusion for this graph is that the older the age, the percentage of 3 points decreases because most of the points are in a range of 20 to 35 years of age.
After 40 years, there are only 3 points, which indicates a very significant decrease in the percentage of points at older ages.

Approximately how much fabric of each color will be needed to make a single parachute canopy? 88. 5 ft 88. 5 ft² 265. 5 ft 265. 5 ft².
The 88.5 ft² fabric of each color will be needed to make a single parachute canopy.
Given
The canopy of a parachute is a semicircle with a radius of 13 feet.
A company that is making parachutes for a Fourth of July celebration wants each parachute to be made from equal parts of red, white, and blue fabric.
What is the surface area of a semicircle?The area of a semicircle is half of the area of the circle.
The first step is the surface area of the semicircle.
The surface area of a circle is;
[tex]\rm Surface \ area=\pi r^2\\\\Surface \ area=3.14 \times 13^2\\\\Surface \ area =530.929[/tex]
Since the semicircle, we divide this by 2.
S.A of the parachute is;
[tex]\rm =\dfrac{530.929}{2}\\\\= 265.4645[/tex]
To get the fabric is needed for each color we divide this by 3.
The fabric needed for each color is;
[tex]\rm= \dfrac{265.4645}{3}\\\\=88.5[/tex]
Hence, the 88.5 ft² fabric of each color will be needed to make a single parachute canopy.
