Answer:
∠b = 88 - 5x
Step-by-step explanation:
If a and b are complementary, then sum of two angles is 90
∠a + ∠b = 90
5x + 2 + ∠b = 90
∠b = 90 - 5x - 2
∠b = 88 - 5x

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second. y=-16x^2+242x+73
Answer:
t = 15.42 s
Step-by-step explanation:
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation.
[tex]y=-16x^2+242x+73[/tex]
We ned to find the time when the rocket will the ground. For this, y = 0
[tex]-16x^2+242x+73=0[/tex]
It is a quadratic equation whose solution is given by :
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]
Here, a = -16, b = 242 and c = 73
[tex]x=\dfrac{-b+ \sqrt{b^2-4ac} }{2a}, x=\dfrac{-b-\sqrt{b^2-4ac} }{2a}\\\\x=\dfrac{-242+ \sqrt{(242)^2-4(-16)(73)} }{2(-16)}, x=\dfrac{-242- \sqrt{(242)^2-4(-16)(73)} }{2(-16)}\\\\=-0.295\ s, 15.42\ s[/tex]
Neglecting negative value.
So, it will hit the ground in 15.42 s.
Answer:
t = 15.42 s

Which theorem is not a valid theorem to show that two triangles are congruent?
A. SAS Triangle Congruence Theorem
B. SSA Triangle Congruence Theorem
C. ASA Triangle Congruence Theorem
D. AAS Triangle Congruence Theorem
Answer:
B
Step-by-step explanation:
I got 100 on my test and that was my answer
This is about Knowledge of Congruence Theorems of Triangles.
Option B is not Valid
In Congruence theorems, we have 4 major types which are;
1) SSS Congruency Theorem; This one denotes Side - Side - Side and it means that if 3 sides of a triangle are equal to corresponding 3 sides of another triangle, then they are both congruent.
2) SAS Congruency Theorem; This one denotes Side - Angle - Side and it means that if 2 sides and one angle of a triangle are equal to corresponding 2 sides and one angle of another triangle, then they are both congruent.
3) ASA Congruency Theorem; This one denotes Angle - Side - Angle and it means that if 2 angles and the included side of a triangle are equal to corresponding 2 angles and the included side of another triangle, then they are both congruent.
4) AAS Congruency Theorem; This one denotes Angle - Angle - Side and it means that if 2 angles and the non-included side of a triangle are equal to corresponding 2 angles and the non-included side of another triangle, then they are both congruent.
Looking at the options, the only one that is not Valid is Option B.

Points c (-5,8) and d (2,5) lie in line cd, if points c and d are created by translating points c and d left 6 units, what is the slope of line c’
Answer:
Step-by-step explanation:
Remark
Moving 6 points left is not going to alter the slope (or it shouldn't).
The x value has to have 6 subtracted from it. Leave the y value alone.
Givens
C: (-5-6,8) = (- 11,8)
D: (2-6,5) = (-4,5)
Formula
m = (y2 - y1)/(x2 - x1)
Solution
m = (8 - 5)/(-11 - - 4)
m = 3 / - 7
m = - 0.429
Check
Let's find the slope of the original points.
(8 -5)/(-5 - 2) = 3/-7 which is the same thing.
At Springfield Middle School, there are n 7th graders, and p% of them play at least one sport. Which expression represents the number of students who do not play any sports? 4©Success Academy Charter Schools 2020 A p n B .01np 0C 100 (100−p)nD .01 (1−p)nE 00(1 )n 1 −p
Answer:
(1-0.01p)/n
Step-by-step explanation:
Mathematically;
Percentage of student playing at least one sport = 100% - Percentage of students playing no sport
Mathematically, that would be;
Percentage playing no sport = 100% - p%
So, to find this in n 7th graders
we have;
(100-p)/100 * n
= 100-P/100n = 1/n - P/100n
= 1/n - 0.01p/n
= (1-0.01p)/n

A horse farm is developing a new indoor arena in a rectangular buliding. They want the width of the building to be 3 wide feet and the length to be 4y+8 feet. Write an expression in the simplist form to represent the are a of the building in terms of y.
Answer:
The area of the building in terms of y in its simplest form is 12(y + 2)
Step-by-step explanation:
Since the area of a rectangle is A = LW where L = length and W = width. From our question, the width of the rectangular building is 3 feet. So, W = 3 feet and its length is 4y + 8 feet. So, L = 4y + 8 feet.
So, the area of the building in terms of y is A = LW
= (4y + 8) × 3
Factorizing out 4 from the expression, we have
= 4(y + 2) × 3
= 12(y + 2)
So, the area of the building in terms of y in its simplest form is 12(y + 2)

The price of some medication was increased from $8 to $12. By what percentage was the price of the medicine increased?
Answer: 25 percent
Step-by-step explanation:
The price of the medicine was increased by 50%.
Given,
The price of some medication was increased from $8 to $12.
We need to find by what percentage the price of the medicine increased.
How do we find a percentage increase?The formula used is given as:
Percentage increase = [tex]\frac{Final~amount - Initial~amount} {Initial ~amount}[/tex] x 100
Find the initial amount.
= $8
Find the final amount.
= $12
Find the percentage increased.
= ($12 - $8) / $8 x 100
= 4/8 x 100
= 1/2 x 100
= 50%
Thus the price of the medicine was increased by 50%.

How can you use the properties of operations to evaluate
this expression?
18 + 4(28)
Answer:
Well on of the properties states that unless there are parenthesis, you multiply and divide first then you add and subtract. So, first we multiply 28*4 and that leaves use with 112, now if there is no more multiplication, division, or parentheses, and there's not. We can continue all we do is add 18+112 and we get our answer of 130.
Answer: Use the distributive property and expand 28, then distribute the 4 to 20 and the 4 to 8. Then you have 18 + 80 + 32. Use commutative property to reverse the order of 32 and 80 so that 18 and 32 are friendly numbers to add.
