It is the second line after 2. the number line goes up in 0.2
Step-by-step explanation:
it is -12.5°C outside when the temperature starts increasing by 2.5°C each hour. How long will it take for the temperature to reach -5°C?
Answer: 3 hours
Step-by-step explanation:
The span between -12.5 and -5 is 7.5. Divide that by 2.5 (since that’s the change) and that’ll give you the amount of time it takes.

Answer:
carry across the-5
minus turns into a +
looks like this
+5+15=m
can someone help me please what is m
Answer:
m = 20
Step-by-step explanation:
We have two fractions and are asked to find m.
When we have a question like this, cross multiplying is our key, to find m, we need to first find the value of the denominator of the other fraction and the numerator of the same fraction m is in.
Therefore :
[tex]\frac{8}{m} = \frac{6}{15}[/tex]
[tex]\frac{8*15}{m*6}[/tex]
What is 8 * 15?
120.
Now we need to find what times 6 equals 120 to get m.
Divide 120 by 6
20
Therefore, m is equal to 20

Joe would like to paint a rectangular shaped wall. The measures of dimensions of the wall are 8 inches by 4 inches. Every 1 inch represents 3 feet of the actual wall. If the cost of the painting is $2.50 per square feet, find the total cost of paint needed for the entire wall.
Answer:
$90
Step-by-step explanation:
8 + 4 = 12
12 x 3 (3 feet for each inch) = 36
36 x 2.50 (cost per square foot) = $90
Answer:
$240
Step-by-step explanation:
8 x 4 is 32
32 x 3 is 96
96 x 2.5 is 240

Find the 44th term.
Answer:
The 44th term is 23
Step-by-step explanation:
Arithmetic Sequences
The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
[tex]a_n=a_1+(n-1)r[/tex]
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
If at least two consecutive terms are given, we can find the common difference by subtracting them.
We are given the terms 152, 149, 146,...
The common difference is
r = 149 - 152 = -3
The first term is a1=152.
Now we apply the general formula to find the term n=44
[tex]a_{44}=152-3(44-1)[/tex]
[tex]a_{44}=152-3(43)[/tex]
[tex]a_{44}=152-129=23[/tex]
The 44th term is 23

Find x
16 ft
х
12 ft
Answer:
x = 20
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
x² = 12² + 16² = 144 + 256 = 400 ( take the square root of both sides )
x = [tex]\sqrt{400}[/tex] = 20

The cost of holding a children's birthday party at a rollerskating rink is a function of n, the number of people in the party. The cost function C can be represented with this set of rules:
Question: How much will it cost with 20 people?
Answer: It would cost $150 for a party of 9 people and it would cost $260 for 20 people
Step-by-step explanation:
The number 9 falls in between 0<n<_ 12 so the cost is 150
The number 20 falls in between 12<n<_ 20 so the cost is 260

What is the classification of the triangle by its angle and by its sides?
[tex]\color{plum}\tt\bold{(A) \: acute , \: equilateral}[/tex]
○=> Steps to derive correct option :▪︎In this triangle all angles are less than 90°. We know that angles of a triangle which are less than 90° in measure will be called acute angles. Thus, this triangle is an acute angle when we classify it by it's angles.
▪︎All sides of this triangle are equal. We know that when all sides of a triangle are equal, it is to be called an equilateral triangle. Thus, this triangle is an equilateral triangle when we classify it by it's sides.
Therefore, the correct option is (A) acute, equilateral

What was the total amount of water in the tank before it was drained
450 gallons
510 gallons
560 gallons
570 gallons
Total amount of water before it was drained will be 510 gallons.
What is rate?"It is a ratio in which the two terms being compared have different units."
For given question,
We have been given a table for the number of gallons of water left in the tank after being drained for two amounts of time.
First we find the rate at which the water was drained from the tank.
[tex]r=\frac{450-330}{30-10}\\\\ r=\frac{120}{20}\\\\ r=6~gallons~per~minutes[/tex]
Let the amount of water in the tank before it was drained = 'x' gallons
And the initial time = 0
Using the rate formula,
[tex]r=\frac{x-450}{10-0}\\\\ 6=\frac{x-450}{10}\\\\ 60=x-450\\\\x=450+60\\\\x=510~gallons[/tex]
Therefore, total amount of water before it was drained will be 510 gallons.

The freezing point of water is 32°F. When water is at or below this temperature, it is in solid form. Which statements are true about the inequality that represents the temperatures at which water is in solid form, and its graph? Check all that apply. The number 32 is part of the solution set. The circle on the graph is open. The circle on the graph is closed. The arrow on the graph points to the left. The arrow on the graph points to the right.
Answer:
The number 32 is part of the solution set
The circle on the graph is closed
The arrow on the graph points to the left
Step-by-step explanation:
The number 32 is part of the solution because it said that water freezes at 32 degrees when it is at or below 32
The circle on the graph is closed because 32 is part of the answer , when the solution is showed then the circle is closed.
Last but not least the arrow on the graph points left because water freezes when it is at 32 or below 32 degrees, so when it points left the numbers become lower.

The aspect ratio, the ratio of the width to the height, of various computer monitors is listed in the table below.
Answer: Monitor C is the different one.
Step-by-step explanation:
The aspect ratio is the relationship between width and height.
So we only need to see the quotients between width and height for each monitor and see which quotient is different.
Monitor A:
Quotient = 1152/864 = 1.333....
Monitor B:
Quotient = 800/600 = 1.333...
Monitor C:
Quotient = 1920/1080 = 1.777...
Monitor D:
Quotient = 1600/1200 = 1.333...
We can see that the one with a different aspect ratio is monitor C.
