What are the dimensions of a rectangular wall that can be constructed with 100 feet of brick that will maximize the area enclosed by that brick?
Answer:
Step-by-step explanation:
25ft x 25ft
Maximum Area with Fixed Perimeter
In order to have a perimeter of 100 feet, that means that each side needs to be 25 feet long. The area would then be 25ft x 25ft, or 625ft2.

Hey there!
The first expression is
5x+15
The equivalent expressions are
5(x+3)
- the opposite of the Distributive Property: 5(x+3)=5x+15
Plus
isn't 5*x+5*3 the same as 5x+15?
Yeah, it is :)
Hence, the equivalent expressions are
[tex]\boxed{\boxed{\bold{Option\;A \;and\;Option\;B}}}[/tex]
[tex]\rule{200}{2}[/tex]
In order to simplify this expression, we need to combine like terms:
11+12y-3-y
The y's are like terms:
11+12y-y-3
11+11y-3
Can you spot any other like terms here? That's right, 11 and -3:
11-3+11y
8+11y
Hence, the equivalent expression is
[tex]\boxed{\boxed{\bold{11y+8}}}[/tex]
Hope everything is clear.

What is Trigonometric ratio?Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled.
Given that, The angle of elevation from a boat to the top of a lighthouse is 25°, the lighthouse is 150 feet tall.
Let the distance from the boat to the lighthouse be x
tan25° = 150/x
x = 150/tan25°
x = 321.67
Hence, the distance from the boat to the lighthouse 321.67 ft.

In the addition problem below, the digits B and C represent a number different from any of the other numbers shown (that is, not 1, 4, 5, 6, or 9. B5+C9=164
B5 + C9 = 164
Split the numbers.
B0 +C0 +14 = 164.
B0 + C0 = 150
B + C = 15
B cannot be 1, 2, 3, 4, or 5 because that forces C to be a two digit number and C only represents 1 digit.
B cannot be 6 or 9 because they are present.
B can only be 7 or 8. C can also be 7 or 8.
Therefore, B = 7 and C = 8, OR B = 8 and C = 7.

Nancy made 20 ounces of a snack mix that was 1/5 peanuts, 30% raisins, and 5 ounces of chocolate chips. the rest was granola how many ounces of granola were in Nancy's snack mix?
Answer:
5
Step-by-step explanation:
First of all, we have a lot of different forms of part/whole's. We have a fraction, a percentage, and a number. How do we make this work???
Let's convert our percent and fraction to ounces, because that is what the question is talking about.
1/5 of 20
1/5=x/20
20=5x
/5 /5
4=x
Now lets convert our percent into ounces.
30% of 20
30/100=x/20
30(20)=100x
600=100x
/100 /100
6=x
Now we have our ounces, we now need to find what is the granola. To do that, we need to add the number of everything else, and then subtract that by the total ounces.
4+6+5=15
20-15=5
The answer would be 5 ounces of granola!

Which equation is equivalent to startroot x squared 81 endroot = x 10? x 9 = x 10 x 9 = x2 20x 100 x2 81 = x2 100 x2 81 = x2 20x 100
The equation [tex]\rm \sqrt{x^2 + 81} = x + 10[/tex] is equivalent to [tex]\rm x^2 + 81 = x^2 + 20x + 100[/tex]. Then the correct option is D.
What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
The equation is given below.
[tex]\rm \sqrt{x^2 + 81} = x + 10[/tex]
Squaring both sides, we have
[tex]\rm (\sqrt{x^2 + 81})^2 = (x + 10)^2\\\\x^2 \ \ +\ \ 81 \ \ = x^2 + 20x + 100[/tex]
Thus, the equation [tex]\rm \sqrt{x^2 + 81} = x + 10[/tex] is equivalent to [tex]\rm x^2 + 81 = x^2 + 20x + 100[/tex]. Then the correct option is D.

Find the perimeter of one piece of rectangle.
2. A rectangle has a length of 30 cm and a width smaller
by 5 cm. What is its perimeter?
If Karen cut her square cardboard into two equal rectangles, the perimeter of those rectangles is 180cm. On the other hand, if the rectangle is 25 cm wide, the perimeter would be 110 cm.
What is the perimeter of a geometric figure?
The perimeter of a geometric figure is the measure of the length of all its sides. In this case, if Karen has a square of cardboard with a side of 60cm, it can be inferred that she would have two rectangles with a height of 30cm and a base of 60cm, so the perimeter would be:
30cm + 60cm + 30cm + 60cm = 180cmOn the other hand, if the rectangle has a base of 30cm and a height of 25cm, the perimeter would be:

Angle Relationship: Alternate exterior angles
x = -10
Angle measurement: 51 °
Step-by-step explanation:
These angles are located "outside" the two parallel lines but on opposite sides of the transversal, therefore they are alternate exterior angles.
Alternate exterior angles are congruent, therefore the angle must be 51 °
51 = 61 + x
subtract 61 from both sides
x = 10

Answer:
<2, <5, and <7.
Step-by-step explanation:
<2 and 72°, are vertical angles. Vertical angles are congruent. Therefore, <2 ≅ 72°.
<7 and 72° are corresponding angles. Corresponding angles are congruent, therefore, <7 ≅ 72°.
<5 and 72° are alternate interior angles. Alternate interior angles are congruent, therefore, <5 ≅ 72°.
Angles that are congruent to 72° are <2, <5, and <7.
