Answer: 7
Step-by-step explanation:
2−(−4)+3+(−6)−(−2)2
solution:
– x – = +
– x + = –
= 2−(−4)+3+(−6)−(−2)2
= 6 + 3 + ( – 6) – ( 2 ) 2
= 9 + ( –6 ) – ( –2 ) 2
= 3 – (–2)2
= 3 – ( –4 )
= 7
To solve any expression the BODMAS priority rule is applicable. Thus, the solution of the expression is 7.
The given expression is [tex]2-(-4)+3+(-6)-(-2)2[/tex]
Apply the BODMAS priority rule to the above expression.
To set the priorities of mathematical operations, the BODMAS is applied. BODMAS rule can be explained below:
B stands for brackets.
O stands for of, and or terms.
D stands for divide.
M for multiply.
A for addition.
S for subtraction.
Therefore, apply the BODMAS and solve the expression further.
[tex]\begin{aligned}2-(-4)+3+(-6)-(-2)2&=2-(-4)+3+(-6)-(-4)\\&=2+4+3-6+4\\&=7\end{aligned}[/tex]
Thus, the solution of the expression is 7.

square feet of stone does Amir need to cover on his patio?
Answer: 108ft^2
Step-by-step explanation:
First, at the top we have two triangle rectangles.
The area of a triangle rectangle is equal to the product of their cathetus divided by two.
We know that one common cathetus for both triangles is 6ft.
And both share the bottom line that is 14ft long, so half of that corresponds to each triangle.
14ft/2 = 7ft
Then each triangle has a cathetus of 6ft and one of 7ft.
Then the area of each triangle rectangle at the top is:
6ft*7ft/2 = 21ft^2
And we have two of them, so the area for now is:
A1 = 21ft^2 + 21ft^2 = 42ft^2.
Now let's look at the bottom part, we can divide this into two triangle rectangles and one rectangle.
First, bottom side is 8ft, then the difference between this side and the 14ft one is:
14ft - 8ft = 6ft
(We calculate this because we are making a rectangle, then the bottom side length must be equal than the top one).
Then we have a surpass of 6ft, which we will divide into both triangle rectangles (3ft for each, this is one of the cathetus).
And we can see that the cathetus shown of this triangle rectangle is 6ft (this is also the other side of our rectangle)
Then we have two triangles with cathetus 6ft and 3 ft, the area is:
A = 6ft*3ft/2 = 9ft^2
And we have two of them, then A2 = 18ft^2.
And the rectangle is 8ft by 6ft, the area is:
A3 = 8ft*6ft = 48ft^2
Then if we add all the areas that we found, we have:
A1 + A2 + A3 = 42ft^2 + 18ft^2 + 48ft^2 = 108ft^2

Television sizes are described by the length of their diagonal measure. What would be the listed size of the TV shown? (to the nearest whole inch)
1,424
32
38
20
Answer:
38 inches
Step-by-step explanation:
since we are finding the diagonal we are going to use the equation a^2+b^2=c^2
so if we do substitution we would have 32^2+20^2=C^2
32^2= 1024
20^2= 400
so,
1024 + 400 = C^2
1424 = C^2
to get rid of the C^2 we have to take the square root of it. But whatever we do on one side of the equation we have to do on the other side so,
C = sqrt(1424)
C = 37.73
C = 38 inches

A bag contains 39 colored marbles. There are 6 blue marbles, 14 red marbles, 8 yellow marbles, and 11 clear marbles. What is the ratio of blue to red marbles?
Answer:
3 to 7
Step-by-step explanation:
blue to red
6 to 14
Divide each side by 2
6/2 to 14/2
3 to 7
Answer:
The ratio would be 6:10 or 6/10 ( 3/5) or 0.6.
Step-by-step explanation:
Why? A ratio is comparing two numbers with a fraction, colon or decimal or percent.
Well there are 6 blue marbles out of the 35 colored marbles. And there are 10 clear marbles.
The question is asking for a blue/clear. It is easy to get confused and put clear/blue. So that is why 6:10 is the ratio.

if a circle's circumference is 15 inches what is its radious? leave the symbol pi in your answer
Answer:
the radius is 2.38
Step-by-step explanation:
use the formula c=2pi r
Answer:
15/2π
Step-by-step explanation:
If the circumference is 15 inches, we can create an equation using the following formula:
Circumference of circle = 2 x π x radius
which is C = 2πr
Now, substituting our value of the circumference (15) into the equation, we get:
15 = 2πr
In order to find r, the radius, we must divide both sides by 2π, which makes r the subject. This cancels out the 2π on the right side, leaving us with:
15/2π = r
So the radius is 15/2π.

A statue at the park needs to be moved. Workers need to move it 7 yards north and 20
yards west. Which of the following represents the job they must do?
a) ( − 20, + 7)
b) ( + 7, + 20)
c) ( + 20, + 7)
d) ( − 7, − 20)
Answer:
the answer is a) (-20, +7)
Step-by-step explanation:
This because by moving the statue north, they are moving it up, and bye moving west they move it to the left. You can tell what is positive and negative by visualizing a graph. Going north is like moving up the y-axis, so you add 7 to the y coordinates. And moving it west would be like moving the statue towards the negative side of the x-axis, thus subtracting 20.

Aiden is a spice trader. He charges $5 for 1 kilogram of cumin seeds, which is the smallest amount he sells. The largest amount of cumin seeds Aiden can sell is 1000 kilograms, which cost $2000 . P(w) models the price (in dollars) of 'w' kilograms of cumin seeds in Aiden's shop. Which number type is more appropriate for the domain of p ?
Integers/Real Numbers
A. 1≤w≤1000
B. 5≤w≤1000
C. 1≤w≤2000
Answer:
[tex]1 \leq\ w\leq\ 1000[/tex]
Step-by-step explanation:
Given
Charges: $5 for 1 kg
Charges: $2000 for 1000 kg
w represents kilograms
P(w) represents Price
Required
What's the domain of P
Start by representing P as a function of w
When
[tex]w = 1\ kg[/tex]
[tex]P(1) = \$5[/tex]
[tex]w = 1000\ kg[/tex]
[tex]P(1000) = \$2000[/tex]
The domain of P are the values of w and is represented as follows;
[tex]1 \leq\ w\leq\ 1000[/tex]
Hence;
Option A answers the question
The number type most appropriate for the domain of p is real numbers and the domain of p is A. 1 ≤ w ≤ 1000
Since Aiden charges $ 5 for 1 kilogram of cumin seeds, which is the smallest amount he sells. and the largest amount of cumin seeds Aiden can sell is 1000 kilograms, which cost $2000.
Since P(w) models the price in dollars of w kilograms of cumin seeds in Aiden's shop.
We see that P(1) = $ 5 and P(1000) = $ 2000.
So, $ 5 ≤ P(w) ≤ $ 2000 which is the range and the domain is
1 ≤ w ≤ 1000
And since w is a continuous variable, the number type most appropriate for the domain of p is real numbers and the domain of p is A. 1 ≤ w ≤ 1000
So, the number type most appropriate for the domain of p is real numbers and the domain of p is A. 1 ≤ w ≤ 1000

Sort the following objects by length. Place the shortest object at the top.
Answer:
Ok, here we have two points A and B.
The shorter object will be the second option, AB with a line on top, this is a segment, so the length of this object is equal to the distance between A and B.
The next one is AB with an arrow pointing to the right, this is ray, is a line that starts in A and passes through B, and continues infinitely.
The third will be the bottom option, AB with a double-arrow on top, this is the notation for a line that passes through A and B, and it extends to infinity in both directions.
