ANSWER: D.180
EXPLANATION: A straight angle is 180 degrees
A straight angle changes the direction to point the opposite way. Sometimes people say "You did a complete 180 on that!" ... meaning you completely changed your mind, idea or direction.

Suppose compact fluorescent light bulbs last, on average, 11,500 hours. The distribution is normal and the standard deviation is 400 hours. What percent of light bulbs burn out within 12,300 hours?
Answer:
2.275%
Step-by-step explanation:
The first thing to do here is to calculate the z-score
Mathematically;
z-score = (x-mean)/SD
from the question, x = 12,300 hours , mean = 11,500 hours while Standard deviation(SD) = 400 hours
Plugging the values we have;
z-score = (12,300-11,500)/400 = 800/400 = 2
Now, we want to calculate P(z ≤ 2)
This is so because we are calculating within a particular value
To calculate this, we use the z-score table.
Mathematically;
P(z ≤ 2) = 1 - P(z > 2) = 1 - 0.97725 = 0.02275
To percentage = 2.275%

Find the value of c so that the polynomial P ( x ) = 4x 3 + c x 2 + x + 2 have the same remainder when it is divided by x-2 and x+1?
Answer:
Step-by-step explanation:I don't say you have to mark my ans as brainliest but if you think it has really helped you please don't forget to thank me ...
For the polynomial P (x) = 4x³ + cx² +x + 2 the value of c is -13.
What is polynomial?Polynomial is an algebraic expression that has more than two terms. In other words, it is a combination of different variables with mathematical operations.
The given equation of polynomial is,
P (x) = 4x³ + cx² +x + 2 (1)
Since, When polynomial is divided by x-2, and x+1 it gives the same remainder,
This implies that at x=2 and x=-1, the value of the polynomial will be equal.
P(2)=P(-1)
4×(2)³+c(2)²+2+2=4×(-1)³+c(-1)²+(-1)+2
32+4c+4=-4+c+1
3c=-3-36
3c=-39
c=-13
So, the value of c is -13.

the perimeter of a triangle is 12b+5. Two sides have the following length:4b and 3b+15. What is the length of the third side?
Answer:The length of the third side 2.5.
Step-by-step explanation:
We already know the length of two side but we don’t know the length of one side so we will represent it by b and we know they three lengths add up to 12b+5.
4b + 3b+15 +b =12b + 5
Solve for b.
8b +15=12b +5
-8b -8b
15+4b +5
-5 -5
4b/4=10/4
B=2.5
So the length of the third side is 2.5
4(2.5) + 3(2.5)+15+2.5=12(2.5)+5
35=35

B) V = 4/3(3.14)(4.5)2
C) V = 4/3(3.14)(4.5)3
D) V = (3.14)(4.5)3
2)
Determine the volume of the given sphere. (nearest tenth)
A) 91.1 cubic units
B) 286.1 cubic units
C) 381.5 cubic units
D) 401.6 cubic units
Step-by-step explanation:
(1) The radius of sphere is 4.5 units.
The volume of volume of sphere is given by :
[tex]V=\dfrac{4}{3}\pi r^3[/tex]
[tex]\pi=3.14\ , r=4.5[/tex]
So,

Mica and Denise are reading the same novel. Mica has read 1/2 of the novel, and Denise has read 2/5 of the novel. If Mica has read 216 pages more than Denise, how many pages are totally for this novel?
Answer:
The novel has 2160 pages.
Step-by-step explanation:
The number of pages of the novel is x.
Mica has read 1/2 of the novel, so x/2 = 0.5x.
Denise has read 2/5 of the novel, so 2x/5 = 0.4x.
Mica has read 216 pages more than Denise
This means that:
0.5x - 0.4x = 216
0.1x = 216
x = 216/0.1
x = 2160
The novel has 2160 pages.
What is the rate of change
Answer:
Slope = 0
Step-by-step explanation:
Let's use the equation [tex]\frac{y2 - y1}{x2 - x1}[/tex] for this problem.
We have two points: (2,0) and (-2, 0)
Let's plug them both into the equation shown above.
[tex]\frac{0 - 0}{-2 - 2}[/tex]
Solve.
0 - 0 = 0
-2 - 2 = -4
[tex]\frac{0}{-4}[/tex] = [tex]-\frac{0}{4}[/tex] = 0
A zero in the numerator means this equation has a slope of 0.
Any line with a slope of 0 is a horizontal line.
Slope (rate of change) = 0

Gabriel invested $900 in an account paying an interest rate of 3 1/4 % compounded daily. Daniel invested $900 in an account paying an interest rate of 3 3/8 % compounded continuously. After 19 years, how much more money would Daniel have in his account than Gabriel, to the nearest dollar?
Answer:
$40
Step-by-step explanation:
The earnings of Gabriel can be calculated with the formula:
P = Po * (1 + r/n)^(nt)
Where P = 900, r = 0.0325, n = 365 and t = 19
So we have:
P = 900 * (1 + 0.0325/365)^(365*19) = $1,668.81
The earnings of Daniel can be calculated with the formula:
P = Po * e^(rt)
Where Po = 900, r = 0.03375 and t = 19
So we have:
P = 900 * e^(0.03375*19) = $1,708.97
So the amount that Daniel will have more than Gabriel is:
1708.97 - 1668.81 = $40.16
Rounding to nearest dollar, the difference is $40

Answer:c
Step-by-step explanation:
how do I simplify this algebraic expression 3x+2a-4x
Start by changing the -4x to + -4x.
So we have 3x + 2a + -4x.
To simplify, we can only combine what are called our like terms and in this problem, we have a pair of like terms in our x terms.
3x + -4x simplifies to -x.
So our answer is -x + 2a.
Note that if you wrote your answer as -1x + 2a, it means the same thing. However, as we move farther into math, we usually tend to drop the -1 or 1 that is in front of a variable since it's implied

What is the probability of rolling a number less than 5?

An adult ticket at an amusement park costs $29.95 and a child’s ticket costs $21.95. A group of 15 people paid $353.25 to enter the park. How many were children?
Write the equations:
a +c = 15
a = 15-c
29.95a + 21.95c = 353.25
Replace a in the last equation:
29.95(15-c) + 21.95c = 353.25
Simplify:
449.25 - 29.95c + 21.95c = 353.25
449.25 - 8.00c = 353.25
Subtract 449.25 from both sides:
-8.00c = -96.00
Divide both sides by -8.00:
c = -96 / -8
c = 12
There were 12 children.
