An albatross is a large bird that can fly 600 kilometers in 15 hours at a constant speed. Using LaTeX: dd for distance in kilometers and LaTeX: tt for number of hours, an equation that represents this situation is LaTeX: d=40td = 40 t . What are two constants of proportionality for the relationship between distance in kilometers and number of hours?
Answer:
The constant is 40Step-by-step explanation:
According to the question we are given an equation that represents the given situation as d = 40t where;
d is the distance in km
t is the time in seconds.
The given function is a direct proportionality. For example if p is directly proportional to q, this is expressed as p ∝ q where ∝ is the proportionality sign. In order to remove the sign we will introduce a constant say "k". The equation will become;
p = kq (p and q are the variables)
A direct proportionality means that as a variable is increasing, the other is increasing and vice versa. Comparing p = kq with d = 40t, we can see that k is equal to 40 and d is directly proportional to t
Hence the constants of proportionality for the relationship between distance in kilometers and number of hours is 40 on comparing.

Writing an equation from words: w+14=5
Solving for w: w=-9
Step-by-step explanation:
Writing an equation from words:
"Sum" means the answer to an addition problem, for example,
1+1=2.
2 would be the sum.
Anyways, the word problem says the sum is 5. So this is what our equation looks like: ?=5
The two numbers being added together are "w" and "14," which leads us to our answer: w+14=5
Solving for w:
w+14=5
Subtract 14 from both sides to get your answer:
w= -9

Answer:
x = 30
Step-by-step explanation:
x and 30° are alternate angles and congruent, thus
x = 30
Answer:
30 degrees
Step-by-step explanation:
according to the angle addition postulate you know that angle 30 plus angle that is 150 so you know that angle x is also equal to 30.

Algebra i P.1 Identify arithmetic and geometric sequences X76 You have prizes to re Farmer Hanson has a plot of tomato plants. There are 2 tomato plants in the first row, 8 tomato plants in the second row, 32 tomato plants in the third row, and 128 tomato plants in the fourth row. What kind of sequence is this? arithmetic geometric both neither Submit
===============================================
Explanation:
The sequence 2,8,32,128,... is geometric
To get a new term, we multiply by the common ratio 4.
2*4 = 8
8*4 = 32
32*4 = 128
To find the common ratio, you pick any term you want, and divide by its previous term
r = (term2)/(term1) = 8/2 = 4
r = (term3)/(term2) = 32/8 = 4
r = (term4)/(term3) = 128/32 = 4
The starting term is a = 2, so the nth term is
a(n) = a*(r)^(n-1)
a(n) = 2*(4)^(n-1)

Answer:
20
Step-by-step explanation:
Number of juniors = 80
Number of seniors = 100
To obtain the same and highest number of student on each float ; we find the highest common factor :
____80 ___100
_2__40___50
_2__20___25
_5__ 4____5
The highest common factor = (2 * 2 * 5) = 20

Sofia wants to rent an apartment. She visits Apartment A which charges $100 for a one-time deposit and $400 per month for rent. She also visits Apartment B which charges $500 for a deposit, but only charges $350 per month in rent. Write and solve an inequality that shows how many months it would take for the total paid to be less for Apartment B.
Answer:
It takes 9 or more months for the Apartment B to pay less than Apartment A.
Step-by-step explanation:
Apartment B:
8 x 350 = $2800
$2800 + $500 = $3300
----------------------------------------------
9 x 350 = $3150
$3150 + $500 = $3650
Apartment A:
$400 x 8 = $3200
$3200 + $100 = $3300
----------------------------------------------
9 x 400 = 3600
3600 + 100 = 3700

state the slope of a line parallel to the given line y-5 = 4 ( x+3)
Answer:
slope = 4
Step-by-step explanation:
Parallel lines have equal slopes.
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 5 = 4(x + 3) ← is in point- slope form
with slope m = 4
A parallel line has a slope of 4
What are the zeros of h (x) = 2x2 – 8x – 10?
Answer:
x=5, -1
Step-by-step explanation:
set the equation equal to 0: 2x^2-8x-10=0
divide both sides by 2 to get x^2-4x-5=0
next factor your new equation to get (x+1)(x-5)
set those equal to zero
now you have x+1=0 and x-5=0
finally, solve for x by subtracting 1 and adding 5
now you have your answer x= 5 and -1

The ratio of the bake time for a pepperoni pizza (P) and a cheese pizza (C) is modeled by the equation: P = 3C - 2. A.) If a small cheese pizza should bake for 12 minutes, how long should you bake a small pepperoni pizza? B.)If a small cheese pizza should bake for 12 minutes, how long should you bake a small pepperoni pizza?
Answer:
34 minutes
Step-by-step explanation:
Given:
Ratio of time for which Pepperoni pizza and cheese pizza should be baked is given as:
[tex]P = 3C - 2[/tex]
Where [tex]P[/tex] is the time for which pepperoni pizza should be baked and
[tex]C[/tex] is the time for which Cheese pizza should be baked.
Also, it is given that a small Cheese pizza should be baked for 12 minutes.
In other words, we are given that: [tex]C=12\ min[/tex]
To find:
For how long small pepperoni pizza should be baked ?
In other words,
[tex]P=?[/tex]
Solution:
Let us put the value of [tex]C[/tex] in the equation of the model.
[tex]P = 3C - 2[/tex]
[tex]\Rightarrow P = 3\times 12 - 2\\\Rightarrow P = 36 - 2\\\Rightarrow P = \bold{34\ min}[/tex]
Therefore, a small pepperoni pizza should be baked for 34 minutes.
