Answer:
-2.1 i guess
Step-by-step explanation:3.1 minus 5 =-2.1
The required expression will be x = 3.1 n - 5
It is given that a number is 5 less than 3.1 times a number "n" .
We have to find the expression for the given statement.
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as multiplication , division , etc.
Let's assume the number be x.
So ,
3.1 times of number n = 3.1 × n = 3.1 n
Let's subtract 5 from the above number, i.e.,
3.1 n - 5
and , the required expression will be ;
x = 3.1 n - 5
Thus , the required expression will be x = 3.1 n - 5

Answer:
The inverse is 1/2x -1/2
Step-by-step explanation:
f(x) = 2x+1
y = 2x+1
Exchange x and y
x = 2y+1
Solve for y
Subtract 1
x-1 = 2y+1-1
x-1 =2y
Divide by 2
x/2 -1/2 = 2y/2
1/2x -1/2 = y

Write the formula for the volume of a cone V = 13π r2 h in terms of h.
Find the height h of a cone with volume V = 32π cm3 and radius r = 4 cm.
Formula:
Height:
Answer:
Formula: V = 1/3πr^2h
Height: 6cm
Step-by-step explanation:
step one:
given information
volume =32π cm^#
radius=4cm
step two:
The formula is
V = 1/3πr^2h
substituting we have
32π =1/3π*4^2*h
32π=16πh/3
π cancels out
step three:
cross multiply we have
32*3=16h
divide both sides by 16 we have
96/16=h
h=6cm

Complete Question
The relationship between altitude and the boiling point is linear. At an altitude of 8300ft, the liquid boils at 194.23 ° F
At an altitude of 4200 ft , the liquid boils at 202.02° F.
Write an equation giving the boiling point b of the liquid, in terms of altitude a in feet . feet . What is the boiling point of the liquid at 2600ft
Answer:
The equation is [tex]y = -0.001943x + 210.3569 [/tex]
At 2600ft the temperature is [tex]y = 205.3051 \ °F [/tex]
Step-by-step explanation:
From the question we are told that
The temperature at 8300ft is 194.23 ° F
The temperature at 4200 ft is 202.02° F
Generally the slope for this relationship is mathematically represented as
[tex]m = \frac{ 202.2 - 194.23}{ 4200 - 8300}[/tex]
=> [tex]m = 0.001943 ^o F / ft [/tex]
Generally the according to the point slope formula is
[tex]y - y_1 = m(x -x_1 )[/tex]
=> [tex]y - 194.23 = -0.001943 (x - 8300 )[/tex]
=> [tex]y - 194.23 = -0.001943x + 16.1269 [/tex]
=> [tex]y = -0.001943x + 210.3569 [/tex]
Now we are given from the question that x = 2600 ft
Then
[tex]y = -0.001943(2600) + 210.3569 [/tex]
=> [tex]y = 205.3051 \ °F [/tex]
A librarian has 16 books that she plans to place in a specific order on her shelf: 7 of them are identical copies of The Shining, 5 of them are identical copies of Carrie, and 4 of them are identical copies of Misery. How many different orders of all 16 of these books are there?
Answer:
3
Step-by-step explanation:
Answer:
140
Step-by-step explanation:
The variables y and x have a proportional relationship, and y = 24 when x = 16.
What is the value of x when y = 36?
x = 16
x = 24
x = 36
x = 54
Answer:
b) x = 24
Step-by-step explanation:
if y is 24 and x is 16, they make the fraction [tex]\frac{24}{16}[/tex]
this can be simplified to [tex]\frac{3}{2}[/tex] if you divide both sides of the fraction by 8.
36/3 is 12, and 12 * 2 = 24.
so, x = 24
Answer:
x=24 or B is the correct answer.

A fruit stand has 200 apples. They order 19 bags with 12 apple each. They sell 42 bags that have 8 apples each. The owner says they now have about 120 apples. Is the owner's estimate reasonable? The owner's answer is reasonable. They ordered about 320 apples and sold about 240 so they should have about 80 fewer apples than they started with. The owner's estimate is not reasonable. They ordered about 320 apples and sold about 240 so they should have about 80 more apples than they started with. The owner's estimate is reasonable. They ordered about 240 apples and sold about 320 so they should have about 80 fewer apples than they started with. The owner's estimate is not reasonable. They ordered about 240 apples and sold about 240 so they should have about the same number of apples as they started with.
Answer:
The owner's estimate is reasonable. They ordered about 240 apples and sold about 320 so they should have about 80 fewer apples than they started with.
Step-by-step explanation:
Given that:
Number of apples already available with Owner = 200
Number of bags of apples ordered with 12 apples each = 19
Number of apples ordered = 12 [tex]\times[/tex] 19 = 228
OR
Rounding off 19 to 20:
Number of apples ordered = 12 [tex]\times[/tex] 20 = 240
Around 240 apples were ordered.
Number of bags of apples with 8 apples each, sold = 42
Number of apples sold = 42 [tex]\times[/tex] 8 = 336
Rounding off 42 to 40, number of apples sold = around 320
Therefore, 80 more apples were sold than that of apples bought.
So, according to the estimate, there will be 80 fewer apples left than they started with.
Correct answer is:
The owner's estimate is reasonable. They ordered about 240 apples and sold about 320 so they should have about 80 fewer apples than they started with

Equations
#1: Tell whether the function below is linear or exponential.
1 pc
y = 3x - 7
It’s it a linear or exponential
Answer:exponential
Step-by-step explanation:
The sum of 5 amd 8 terms of an A.P is 37 and its 11 term is 32 find the A.P
Sum of 5th & 8th terms of an AP = 37
11th term = 32
Find:A.P
Solution:We know that,
nth term of an AP – an = a + (n - 1)d
Hence,
⟹ a₅ + a₈ = 37
⟹ a + (5 - 1)d + a + (8 - 1)d = 37
⟹ 2a + 4d + 7d = 37
⟹ 2a + 11d = 37 -- equation (1)
Similarly,
⟹ a₁₁ = 32
⟹ a + (11 - 1)d = 32
⟹ a + 10d = 32
⟹ a = 32 - 10d
Substitute the value of a in equation (1).
⟹ 2(32 - 10d) + 11d = 37
⟹ 64 - 20d + 11d = 37
⟹ 64 - 37 = 20d - 11d
⟹ 27 = 9d
⟹ 27/9 = d
⟹ 3 = d
Substitute the value of d in equation (1).
⟹ 2a + 11(3) = 37
⟹ 2a + 33 = 37
⟹ 2a = 37 - 33
⟹ 2a = 4
⟹ a = 4/2
⟹ a = 2
Now,
General form of an ap = a , a + d , a + 2d...
⟶ Required AP = 2 , 2 + 3 , 2 + 2(3)...
⟶ Required AP = 2 , 5 , 2 + 6...
⟶ Required AP = 2 , 5 , 8...
I hope it will help you.
Regards.
Answer:
→ md - 2nd + 3md = 2 * [ a + (n - 1)d ]
→ 4md - 2nd = 2 * [ a + (n - 1)d ]
→ 2(2md - nd) = 2 * (a + nd - d)
→ 2md - nd - a + d = nd
→ 2md - nd - (md - 2nd) + d = nd
[ From equation (1) ]
→ 2md - nd - md + 2nd + d = nd
→ md + nd + d = nd
→ (m + n + 1)d = n * d
→ (m + n + 1) = n
