The temperature at 2 am was -12 degrees. At noon the temperature had risen 16 degrees. At 4 pm the temp dropped 8 degrees. What was the temperature at 4 pm
Answer: - 4
because The temperature at 2 am was -12 degrees and At noon the temperature had risen 16 degrees
=> the temperature at noon was -12 + 16 = 4 (degrees)
At 4 pm the temp dropped 8 degrees => the temperature at 4 pm was:
4 - 8 = -4 (degrees)

Does Anybody Know Anything About Angle Bisectors?
Answer:
I know a bit about Angle Bisectors. (the line that splits an angle into 2 equal angles)
Answer:
In geometry, the angle bisector theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle. It equates their relative lengths to the relative lengths of the other two sides of the triangle.

Given a term in a geometric sequence and the common ratio. Find the explicit formula . A) a 3 =-36 , r = 6 b) a 6 =64 , r = 2
Answer:
Step-by-step explanation:
The explicit formula for a GP is expressed as
Tn = ar^{n-1}
a is the first term
n is the number of terms
r is the common ratio
a) If a3 = 36 and r = 6
a3 = ar^3-1
a3 = ar^2 = 36
ar^2 = 36
a(6)^2 = 36
36a = 36
a = 1
Get the nth term
Tn = 1(6)^{n-1}
Tn = 6^{n-1}
b) If a6 = 64 and r = 2
a6 = ar^6-1
a6 = ar^5 = 64
ar^5 = 64
a(2)^2 = 64
4a = 64
a = 16
Get the nth term
Tn = 16(2)^{n-1}
Tn = 16*(2^n/2)
Tn = 8(2^n)

The answer to this question is B, No solution
∠A is complementary to ∠B. The measure of ∠A is (8x+12)∘. The measure of ∠B is half the measure of ∠A.
Write an equation that can be used to determine the value of x. Then solve for x.
The equation that can be used to solve for x is 8x + 12 + 4x + 6 = 90.
The value of x is 6.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
∠A and ∠B are complementary.
This means,
∠A + ∠B = 90
Now,
∠A = 8x + 12
∠B = (8x + 12)/2 = 4x + 6
Now,
8x + 12 + 4x + 6 = 90
12x + 18 = 90
12x = 90 - 18
12x = 72
x = 72/12
x = 6
Thus,
The value of x is 6.

Nathan is using his grandmother's recipe to make pies
On Monday, he used 15 3/4 cups of sugar to make 9 pies
On Tuesday, he used 23 3/4 cups of sugar to make 13 pies
Which of the following must be true? (Select all that apply)
A) He used 1 cup of sugar for every 1 3/4 pies he made
B) He would use 14 cups of sugar to make 8 pies
C) The number of cups of sugar is proportional to the number of pies he made because he used the same number of cups of sugar for each pie
D) The number of cups of sugar is not porptional to the number of pies he made because the increase in the number of cups of sugar between Monday and Tuesday is greater than the increase in the number of pies
E) if Nathan uses 8 3/4 cups of sugar to make 5 pies on Wednesday and then graphs the points, for all the three days, to represent the relationship between the cups of sugar used and the number of pies made, the points would not fall on a straight line

(BRAINLIEST + 30 POINTS) Gumballs cost $0.50 each, and jawbreakers cost $0.30 each. Bob has $3.00 to spend on candy.
Create an inequality that represents the number of gumballs and jawbreakers Bob can buy.
Answer:
3 gumballs and 5 jawbreakers = $3.00
Step-by-step explanation:
30 x 5 = $1.50 (One dollar and 30 cents)
50 x 3 = $1.50 (One dollar and 30 cents)
and if you add those together you get $3.00 because
50 + 50 = 100 or in this question $1.00 and when you add
$1.50 + $1.50 = $3.00

What is the distance between point (3,2) and line y=1/4x-9
Answer:
9.94
Step-by-step explanation:
y = [tex]\frac{1}{4}[/tex] x - 9
y - 2 = - 4(x - 3)
y = - 4x + 14
- 4x + 14 = [tex]\frac{1}{4}[/tex] x - 9
16x - 56 = - x + 36
17x = 92
x = [tex]\frac{92}{17}[/tex]
y = (-4) [tex]\frac{92}{17}[/tex] + 14 = - [tex]\frac{368}{17}[/tex] + [tex]\frac{238}{17}[/tex] = - [tex]\frac{130}{17}[/tex]

20 POINTS An electrician charges a set fee for every house call and then charges an hourly rate depending on how long the job takes. The total cost of the electrician's services can be determined using the equation C=65+60t, where t is the number of hours the electrician spends at the house working. What is the slope of the equation and what is its interpretation in the context of the problem?
Answer:
[tex]the \: slope \: is \to \boxed{60}[/tex]
Step-by-step explanation:
[tex]if \to C=65+60t \\ C=60t + 65 \\ but \: the \: \boxed{ c - intercept} \: is \: in \: the \: form \to \\ c = mt + b \\ hence \to \\ 60t = mt \\ m = \frac{60t}{t} \\ m = 60 \\ the \: slope \: is \to \boxed{60}[/tex]
We want to analyze the given linear equation, we will find that the slope is 60, and it means that he charges 60 per hour.
Linear equations:
A general linear equation is written as:
y = a*x +b
Where a is the slope and b is the y-intercept.
In this case, we have the equation:
c(t) = 60*t + 65
Is easy to identify that the slope is equal to 60.
Given that we know that he charges per hour, and that t represents the number of hours that the electrician worked, we can assume that the slope represents how much the electrician charges per hour.
