Answer:
b = 60
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 63² = 87²
b² + 3969 = 7569 ( subtract 3969 from both sides )
b² = 3600 ( take the square root of both sides )
b = [tex]\sqrt{3600}[/tex] = 60

Consider the following pair of equations:
y = x + 4
y = - 2x - 2
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form. (20 points!)
Answers
Answer:
(-2, 2).
Step-by-step explanation:
y = x + 4
y = - 2x - 2
Substitute y = x + 4 in the second equation:
x + 4 = -2x - 2
x + 2x = -2 - 4
3x = -6
x = -2.
Now substitute x = -2 in the first equation:
y = -2 + 4 = 2.
Check the results by substituting for x and y in equation 2:
2 = -2*-2 - 2 = 4 - 2 = 2. - this checks out.
Answer:
(-2, 2).

Answers
The first step to solve for r is (J) He should divide both sides of the equation by π.
How to solve the formula for r?The equation is given as:
A= πr^2
Divide both sides of the equation by π.
So, we have:
r^2 = A/π
Hence, the first step to solve for r is (J) He should divide both sides of the equation by π.

The width of a triangle of 7 feet longer than its length. Find the dimensions of the rectangle such that the perimeter of the rectangle is 162 feet
Answers
Answer:
Length = 37 feets
Width = 44 feets
Step-by-step explanation:
Given that :
Length = l
Width, w = 7 + l
Perimeter , P of rectangle = 162
Recall:
Perimeter of a rectangle = 2(l + w)
P = 2(l + w)
162 = 2(l + (7 + l))
162 = 2(l + 7 + l)
162 = 2(7 + 2l)
162 = 14 + 4l
162 - 14 = 4l
148 = 4l
l = 148 / 4
l = 37 feets
Width = l + 7
Hence,
Width = 37 + 7 = 44 feets

Please define (provide the meaning) the following forms of rocks:
1. Igneous Rocks
2. Sedimentary Rocks
3. Metamorphic Rocks
Answers
Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon and oxygen, the most abundant elements in the Earth’s crust.

Answers
Answer:
a.) 13 students
b.) 53 members
Step-by-step explanation:
a.) In the given equation of y=4x+13, "x" represents how many years have gone by since the club had started. The number "13" in this equation represents the y-intercept, or the value of "y" when x = 0. Therefore, when "x" is 0 years, there were 13 students in the clubs, meaning that the original group that started the club contained 13 students.
b.) Since the question asks how many members that the club will have after their tenth year and you already know that "x" in the equation y=4x+13 represents the number of years since the club started, all you have to do is plug 10 in for "x" in the equation; so, the equation will now look like this: y=4(10)+13. Keeping PEMDAS in mind, you first multiply 4 and 10 to get 40, and then you add 13 to get an answer of 53 members after year 10.

Compound Interest = 9680
Step-by-step explanation:
The formula of Compound Interest: [tex]A = P(1 + \frac{r}{n} )^n^t[/tex]
Where;
A = Compound Interest
P = Principal amount
r = Rate of interest
n = amount of deposite annually
t = total time
Therefore:
[tex]A = 8000(1 + \frac{0.08}{1})^1^*^2^.^5[/tex]
[tex]A = 8000(1 + 0.08)^2^.^5[/tex]
[tex]A = 8000(1.08)^2^.^5[/tex]
A = 8000(1.21)
A = 9680
Therefore, the compound interest = 9680

OT-50 + 12 = 1-38] = -38 units
OT-50 - 12| = |-62] = 62 units
Plz help
Answers
Answer: Choice D
|-50-12| = |-62| = 62 units
================================================================
Explanation:
Draw out a number line. Mark two points on it at A = -50 and B = 12
The expression |A-B| represents the distance between the two points. So that would be....
|A-B| = |-50-12| = |-62| = 62
Note that negative distance does not make sense. The smallest distance can get is 0. So the result of an absolute value problem is never negative.
-------------------
Slightly alternative method:
If you wanted, you could plot point C on the number like such that C is at 0.
The distance from A = -50 to C = 0 is exactly 50 units
From C = 0 to B = 12 is an additional 12 units
Therefore, the total distance is AC+CB = 50+12 = 62 units
-------------------
Side note: |A-B| is the same as |B-A|. The order of subtraction doesn't matter as long as you use absolute value. If absolute value wasn't there, then A-B is different from B-A.
