A box has 4 sides, two short sides which are width by height and two long sides which is length by height.
A) Surface area = 2(LxH) + 2(WxH)
Surface area = 2(10x4) +2(6x4)
Surface area = 2(40) +2(24)
Surface area = 80 + 48
Surface area = 128 square inches for each box.
128 square inches x 100 boxes = 12,800 square inches.
B) 1 can covers 14,000 square inches which is greater then the total of the 100 boxes, so she will need to buy 1 can of paint.

given m||n, find the value of x. see attachment.
Answer:
6x-8=5x+14
x=22
this is the solution
(6x-8)°=(5x+14)°
_ _ _ _ _ +14= _ _ _ _ _ _-8= x=14+8=22°
(6×22-8)°=124°
(5×22+14)=124°

Answer:
The expression that represents the table is
y=4+2x
when x=3
y=4+2(3) = 10
When x=6
y=4+2(6)= 16.
Do this for all the values of x and you'll get the corresponding value for y

Identify the angle pair as adjacent, vertical, or neither.
3 and 5
Given:
A figure.
To find:
Whether the pair of angle 3 and angle 5 is adjacent, vertical, or neither.
Solution:
Adjacent angle: If two angles are adjacent to each other, it means they have a common vertex, one common side and they are not overlapping each other, then they are called adjacent angles.
Vertical angles: If two lines intersect each other then the opposite angles are known an vertical angles.
From the given figure it is clear that the angle 3 and angle 5 are neither adjacent nor vertical angles.
Therefore, the correct option is B.

You went to a bake sale and bought a whole bunch of
yummies!
Cookies were $1 and Brownies were $2. You spent
$13 total.
What are three combinations of cookies and brownies
that you could have gotten?
Write an equation that represents this situation.
Answer:
If cookies are for $1 and brownies are for $2, let number of cookies = x and number of brownies = y
∴ $1*(x*1) + $2*(y*1) = $13
Step-by-step explanation:
1) You can buy 4 brownies for $2 each = 2*4 = $8
The rest you can buy cookies = 5 cookies = $5
$8+$5=$13
2) You can buy 5 brownies and 3 cookies = $10+$3 = $13
3) You can buy 3 brownies and 7 cookies = $6+$7=$13
Equation: -
If cookies are for $1 and brownies are for $2, let number of cookies = x and number of brownies = y
∴ $1*(x*1) + $2*(y*1) = $13
A rhombus is cut along the diagonals to make four triangles. Which three statements are correct for any rhombus? 1) All four triangles are right-angled. 2) All four triangles are isosceles. 3) All four triangles are congruent. 4) Area of a rhombus = 4 x area of one triangle. 5) Perimeter of rhombus = 4 x perimeter of one triangle.
Answer:
1). All four triangles are right-angled.
3.) All four triangles are congruent.
4) Area of a rhombus = 4 x area of one triangle.
Step-by-step explanation:
If a rhombus is cut into four triangles using diagonals, the three statements that would apply to any rhombus would be that 'all those four triangles would be right-angled,' 'the triangles would be congruent to one another,' and 'area of one triangle * 4 would be equal to the area of the rhombus.'
As we know, the diagonals bisect one another in a rhombus at 90° and the angles opposite to one another are equal. This proves that all four triangles constructed through the diagonals would be ≅ through SSS congruency and perpendicular to one another because the corresponding edges of the congruent triangles are also ≅ . Since the rhombus is divided into four equal parts, the area of one triangle into four would be equals to the area of the rhombus. Thus, options 1, 3, and 4 are the correct answers.

The half-life a particular radioactive
substance is 1 year. If you started with
50 grams of this substance, how much
of it would remain after 3 years?
First, complete the equation:
Remaining Amount =
Answer:
Remaining amount is 6.25 gram
Step-by-step explanation:
After one year what you would be left with is 50/2 which is 25 gram
After the second year, you would be left with 50/4 which is 12.5
After the third year what's left is 50/8 i.e 6.25

the sum of two positive numbers is 588. minimize the sum of the first and three times the second
9514 1404 393
Answer:
{587, 1}
Step-by-step explanation:
The sum will be minimized when the second number is as close to zero as is allowed. If the numbers must be positive integers, the sum is minimized when the numbers are {587, 1}.
If the numbers may be real numbers, then the values that minimize the sum are {588-, 0+}
_____
The "cost" of taking a unit from the sum 588 and assigning it to the second number is that the sum of first and 3 times the second goes up by 3. In order to minimize that sum, the second number must be minimized.

[tex]\frac{1}{14}[/tex] is half of [tex]\frac{1}{7}[/tex]
This would be true because half of a number can be found by multiplying by [tex]\frac{1}{2}[/tex]
If you multiplied [tex]\frac{1}{7} * \frac{1}{2}[/tex]
The numerator is 1 * 1 which is 1
And then the denominator is 7 * 2 which is 14
That would give you [tex]\frac{1}{14}[/tex]

The products of two reciprocals is 0
This is not true
Reason being, reciprocals are just the number flipped. If you times the number by itself, you don't get 0, you get 1.
Ex: [tex]\frac{2}{8}[/tex]
Its reciprocal is [tex]\frac{8}{2}[/tex]
So multiply them together
[tex]\frac{2}{8}* \frac{8}{2}[/tex]
2 * 8 = 16
8 * 2 = 16
[tex]\frac{16}{16} = 1[/tex]

A whole number does not have a reciprocal
This is incorrect. If you think about it, a whole number is just the number, over 1
Ex: [tex]\frac{6}{1}[/tex]
This is still a whole number even though its written in fraction form because if you divide 6 by 1, your still going to get 6.
If you an write it as a fraction, it has a reciprocal.
The reciprocal in this case would be [tex]\frac{1}{6}[/tex]

Find the base of a triangle with an area of 45 square yards and a height of 20 yards.
Answer:
Base, b = 4.5 yards
Step-by-step explanation:
Given the following data;
Area of triangle = 45 square yards
Height = 20 yards
To find the base of the triangle;
Mathematically, the area of a triangle is given by the formula;
Area of triangle = ½ * b * h
Where;
b is the base of the triangle.
h is the height of the triangle.
45 = ½ * b * 20
90 = 20b
Base, b = 90/20
Base, b = 4.5 yards
