Noah spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -13°F. Between 9am and noon, the temperature increased by 6.3°F. Between noon and 3pm, the temperature rose 3.9°F. Between 3pm and 6pm, the temperature decreased by 16.1°F. What was the temperature at 6pm?
Answer:
-18.9 °F
Step-by-step explanation:
First, find the temperature at noon:
-13 + 6.3
= -6.7
Then, find the temperature at 3pm:
-6.7 + 3.9
= -2.8
Then, find the temperature at 6pm:
-2.8 - 16.1
= -18.9
So, the temperature at 6pm was -18.9 °F

The sum of 2 consecutive numbers is 69. What are the numbers?
Answer:
34, 35Step-by-step explanation:
z - some integer
then the consecutive integer would be:
z+1, (or z-1)
the sum is 69 so:
z + z+1 = 96
2z = 68
z = 34
z+1 = 34 + 1 = 35
(or:
z + z-1 = 69
2z = 70
z = 35
z-1 = 35 - 1 = 34)

Step-by-step explanation:
[tex] \sf{ \frac{7}{12} + \frac{5}{6} }[/tex]
Take the L.C.M of 12 and 6
To find L.C.M , first of all find the prime factors of each numbers.
12 = 2 × 2 × 3
6 = 2 × 3
Take out the common prime factors i.e 2 and 3
Also take out the other remaining prime factors : 2
Multiply those all prime factors and obtain L.C.M
L.C.M = Common factors × Remaining factors
= 2 × 3 × 2
= 12

Answer:
≈ 33.3 cm²
Step-by-step explanation:
Given the linear ratio of 2 similar cones = a : b , then
ratio of their areas = a² : b²
Here the ratio of radii = 2 : 3 , thus
ratio of areas = 2² : 3² = 4 : 9
let x be the area of the smaller cone then by proportion
[tex]\frac{4}{x}[/tex] = [tex]\frac{9}{75}[/tex] ( cross- multiply )
9x = 300 ( divide both sides by 9 )
x = 33.33333
Thus
surface area of smaller cone ≈ 33.3 cm² ( nearest tenth )

What is the relationship between the coordinates of the vertices for ABC and the corresponding vertices for A'B'C'? Explain the relationship in terms of n.
Answer:
The ratio of each vertex coordinate on ΔA'B'C to the corresponding vertex coordinate on ΔABC is equal to 2. For example, A(1, 1) → A′(2, 2). This ratio is equal to the scale factor, n.

Which of the following are appropriate names for the angle composed of the rays JK−→− and JL−→? Select the three correct answers.
A. Angle JKL
B. KJL
C. L
D. K
E. J
F. LJK
Answer: KJL, LJK and ∠J
Step-by-step explanation:
We have two rays.
JK and JL.
So the common point of bot rays is the point J.
In the angle notation, we usually write the common point in the middle.
So the possible notations for this angle are:
LJK or KJL.
Also knowing that the vertex of the angle is at the point J, we also could call this angle as:
∠J.
So the correct options are B, F and i suppose that the option D is actually ∠J (you wrote that the option D is only J)

Babysitters earn between $8 and $11 per hour.
A program at a community college can be completed in no fewer than 8 months, but must be completed in less than 11 months.
The dogs at a veterinary clinic are all 8 years old or under or are older than 11 years.
Answer:
A program at a community college can be completed in no fewer than 8 months, but must be completed in less than 11 months.
Step-by-step explanation:
1. The closed dot means the number is equal to and the open dot means the number is less/ greater than
2. The line goes right from the 8 with a closed dot, making x greater than or equal to 8
3. The line goes left from the 11 with an open dot, making x less than ll
4. This means the number must be equal to or greater than 8, and less than 11
The situation that can be represented by the graph is this:
A program at a community college can be completed in no fewer than 8 months, but must be completed in less than 11 months.What is highlighted in the number line?In the number line, numbers 8 to 11 are shaded. This is a range which can mean that the time duration for the completion of a college program cannot be lower that 8 months.
It can also be interpreted to mean that the time span cannot exceed 11 months. Therefore, option C is right.

What is the probability that the measurement of the segment is greater than 3 !!!
Answer:
Probability = [tex]\frac{3}{5}[/tex]
Step-by-step explanation:
Length of segment AD = 12 units
Since, AC = CD
Therefore, AC = CD = [tex]\frac{12}{2}[/tex] = 6 units
Since, AB = BC
Therefore, AB = BC = [tex]\frac{1}{2}AC[/tex] = 3 units
Number of total segments = 5
Number of segments having measure greater than three = 3
(AC = CD = 6 units and AD = 12 units)
Probability that the measure of a segment is greater than 3
= [tex]\frac{\text{Number of segments measuring greater than 3}}{\text{Total number of segments}}[/tex]
= [tex]\frac{3}{5}[/tex]

Step-by-step explanation:
let [tex]x[/tex] be that number[tex](\frac{3}{4} )x = \frac{41}{2}[/tex]
[tex]\frac{3x}{4} = \frac{41}{2}[/tex]
multiply both sides by [tex]4[/tex][tex]\frac{3x}{4} * 4 = 4 * \frac{41}{2} \\3x = \frac{41 }{2} * 2 * 2\\3x = 41 *2 \\3x = 82 \\[/tex]
