Answer:
Part A
12.6 - 0.4x = y
Part B
x = 31.5
Step-by-step explanation:
Part B
12.6 ÷ 0.4 = 31.5 hours
y=12.6-0.4x is the required linear equation and it takes 31.5 hours to completely evaporate the water in glass.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that in the beginning of the experiment, the water level is 12.6 cm.
The water level in a glass decreases 0.4 cm each hour
Let x represent time, in hours, elapsed since the beginning of the experiment and let y represent the water level, in centimeters.
We need to find the linear function, using x and y from above, that determines the water level at a given time, in hours, after the experiment begins.
y=12.6-0.4x
We need to find how long will it take to for all of the water to evaporate.
12.6/0.4 = 31.5 hours
Hence, y=12.6-0.4x is the required linear function and it takes 31.5 hours to completely evaporate the water in glass.

Answer:
part A = 74 part B = 27 part C = 85.33
Step-by-step explanation:
Part A
you do 34 - 12 = 20 then you do 9 * 6 = 54 then you take 20 and 54 and add them together 20 + 54 = 74
Part B
you do 14 * -2 = 28 then you do -3 /3 = 1 then you subtract 28 and 1 = 27
Part C
you do 56 / 3 = 18.67 then you do 44 * 2 = 88+16 =104 then you subtract 18.67 and 104 = 85.33
At a bus station, buses begin their routes at 6:00 a.m. The schedule for two of the buses is
based on the time intervals listed below.
Bus A has a long route and leaves the station every 75 minutes.
Bus B has a short route and leaves the station every 15 minutes.
What is the next time Bus A and Bus B will leave the bus station at the same time?
A 7:00 a.m.
B 7:15 a.m.
C 7:30 a.m.
D 8:30 a.m
To find the next time when Bus A and Bus B leave the station at the same time, we need to find the first common multiple of the time intervals of the two buses.
The time intervals for Bus A are 75, 150, 225, 300, and so on.
The time intervals for Bus B are 15, 30, 45, 60, 75, 90, and so on.
The first common multiple of 75 and 15 is 75, so the next time when Bus A and Bus B leave the station at the same time will be 75 minutes after their last common departure time, which was 6:00 a.m.
Therefore, the next time when Bus A and Bus B will leave the bus station at the same time is 7:15 a.m., which is option B.

Step-by-step explanation:
A translation is when a geometric figure slides up, down, left or right on the coordinate plane. The figure moves its location, but doesn't change its orientation. It also doesn't change its size or shape. When you perform translations, you slide a figure left or right, up or down
basically, everything is just moving around same distance and same direction

What is the total surface area of the prism below? (Can I pls get the whole problem solved step by step, most of it!)
Answer:
672
Step-by-step explanation:
Okay so, the surface area of a figure is just all the areas of the faces added together. The front face ( 9x16 ) would be 144. The back face would be 12x9 or 109. The base would be 20x9 or 180. Now, this is where it might get tricky. The triangles will be 12x20x0.5 or 1/2. The answer for that would be 120. Now since there are two, multiply the 120 by two. ( Technically, since there are two of the same triangles you would not need to multiply by 0.5, but just to be safe i'll do it here. ) Finally, add all the areas together. The final answer is 672. Hope this helps!

Use +,-,x, ÷ and parentheses to connect the numbers 1,3,5 and 7 such that the result is 24.
Answer: (3-1)×(7+5)
Step-by-step explanation:
There are mainly several ways to get 24
- 2×12
- 3×8
- 4×6
- add all of them together
- complicated ones can include large numbers minus another large number
Use try-check-revise, to find the way that fits 24
For this question, we used 2×12, which results in (3-1)×(7+5)

Shannon plots the following points on a number line:
-25
-13
6
19
Which of these points has the lowest absolute value?
Answer: 6
Step-by-step explanation:
The absolute value of a positive number is just the number.
And the absolute number of a negative is its positive.
So absolute value of -25 is 25
Absolute value of -13 is 13
Absolute value of 6 is 6
Absolute value of 19 is 19
So the lowest absolute value is 6
6, because 6 is the amount of numbers away from 0.

Help Me With Functions Part 4.
Answer:
for this one, your answer will be B.X
Step-by-step explanation:
It is X because each element in x is mapped to exactly one element in y.
In X 6 maps to 4,2; in y 6 maps to 6,2; in Z 7 maps to 2,8.
so every element in x should map to exactly one element in y and it is possible only in the set X so the answer is X.

Answer:
Step-by-step explanation:
So you have to remember, area is LxW - Lenth x Width.
Also remember base is bxh - Base x height.
T he rectangle has a area already which is 3x3 = 6 but remember you also have to find the base. So,
you do Area = 50.4 yd²
Step-by-step explanation:
Base dimension of container = 4⅕ by 1⅓ yd
Array: 3 * 3 containers without space
Area covered by the containers
First, it'll be assumed that the container has a rectangular base.
The dimension of the base is measured out as follows:
Length, L = 4⅕ yd
Width, W = 1⅓ yd
Note that this can also be interchanged.
Next, is to calculate the area of 1 container..
Area = 4⅕ yd * 1⅓ yd
Convert mixed fractions to improper fraction
Area = 21/5 * 4/3 yd²
Area = 84/15 yd²
Area = 28/5 yd²
Area = 5.6 yd²
Next, is to calculate the area of the 3 by 3 containers.
Given that the container formed a 3 by 3 array;
This means that there 3 * 3 containers
3 * 3 = 9 containers.
Area of the 9 containers = 9 * Area of 1 container.
Area = 9 * 5.6 yd²
Area = 50.4 yd²
the area covered by the containers is 50.4 yd²

Answer:
Step-by-step explanation:
2 Ms. Salgato doesn’t want to spend more than $375 that in symbols can be expressed as [tex]\leq 375[/tex].
$100 is a constant so it doesn’t multiplies the x. The hour are instead a variable so $40 multiplies the x
so the final answer is
C [tex]100+40x\leq 375[/tex]
9 no less than $455 can expressed as [tex]\geq 455[/tex]
if we solve the inequality [tex]245+d\geq 455[/tex]
we have
[tex]d \geq 210[/tex]
so the final answer is A
13
$130 is a constant, while $3 mulplied a variable. No more means [tex]\leq 190[/tex]
we can now write and solve an inequality:
[tex]130+3x\leq 190 \\ 3x\leq 60 \\ x\leq 20[/tex]
so the answer is C : 20
14
$9 multiplies a variable, a minimum can be expressed as [tex]\geq[/tex]
so the final answer is
B : [tex]9h\geq 81[/tex]
Answer:
2 = C
9 = C
13 = C
14 = B
