Answer:
The equation that relates temperature to depth is y = 28 - 0.065·x
Step-by-step explanation:
Los parámetros dados son;
La temperatura del agua en la superficie = 28 ° C
La temperatura del agua a 200 m por debajo de la superficie = 15 ° C
Dado que la relación es lineal, tenemos;
Sea la pendiente de la relación = m, por lo tanto;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Dónde;
x₁ = 0 m, y₁ = 28 ° C, x₂ = 200 m, y₂ = 15 ° C, tenemos;
[tex]Slope, \, m = \dfrac{15^{\circ}C-28^{\circ}C}{200 \, m-0 \, m} = \dfrac{(-13)^{\circ}C}{200 \, m} = -0.065 ^{\circ}C/m[/tex]
Por lo tanto, la ecuación en forma de pendiente puntual se convierte en;
y - 28 = -0,065 × (x - 0)
y = -0.065 · x + 28 = 28 - 0.065 · x
Por lo tanto, la ecuación que relaciona la temperatura con la profundidad es y = 28 - 0.065 · x.

Evaluate for(+7)-(-3)
Answer:
10
Step-by-step explanation:
When we subtract a negative number, it's basically a double negative, kind of like how we don't use those in English. We want to turn that into a positive, and double negatives are positive.
So, instead of 7-(-3), we get 7+3, or 10
Answer:
10
Step-by-step explanation:
[remember: (+)(+) is (+) itself , (+)(-) is (-) , (-)(-) is (+) ]
(+7)-(-3)
⇒ +7+3
⇒ 10
hope you understood❤

Tangela earns the same amount each week by babysitting. When she started this job, she had $200 in her savings account. The table shows Tangela's savings account balance for her first month of work. Week 0 1 2 3 4 Balance $200 $350 $500 $650 $800 Let x represent the number of weeks Tangela has been working and let y represent Tangela's account balance. Which equation, expressed in Slope-Intercept form, represents the amount of money in Tangela's bank account over time?
y=150x+200
y=200x−150
y=150x−200
y=200x+150
Answer:
y=150x+200
Step-by-step explanation:
Given that:
Week : ____ 0___ 1 ___ 2 ____3 _____4
Balance : __200_350 _ 500 _ 650 ___800
Amount had in savings account = $200 before starting the job
x = number of weeks spent working
y = account balance
Slope intercept formula :
y = mx + c
C = intercept ; value of y when x = 0 = 200
m = slope or gradient = change in salary per month (350 - 200 = 500 - 350 = 650 - 500 = 800 - 650 = 150
Hence,
y = 150x + 200

Step-by-step explanation:
Which of these expressions is equivalent to -2(x - 5)?
-2x + 5
-2x - 10
-2x + 10
-2x-5
Question 3
Mathematics
The equivalent expression is: -2x + 10. therefore the correct option is C.
What are equivalent expressions?Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.
From the distributive property;
-2(x - 5)
Then, multiply -2 and -5
-2 * x = -2x
-2 * -5 = 10
because two negatives make a positive
Therefore the answer would be -2x+10.
Hence,The equivalent expression is: -2x + 10. therefore the correct option is C.

express the ratio 60cm to 20m
Answer:
3 cm : 1 cm
Step-by-step explanation:
1. 60 : 20
2. divide 10 on both sides = 6 : 2
3. divide by 2 on both sides = 3 : 1
4. 3 cm : 1 cm
I'm so sorry, I just read the ratio is 60 cm to 20 M
So edit:
convert both into a unit, we'll take m.
1 cm = 100 m
so 60 x 100 = 60000 m
= 60000 m : 20 m
= divide by 20 in both sides...
= 3000 m : 1 m

Penguins can swim at a speed of up to 33 ft./s use dimensional analysis to convert the speed to miles per hour 1 mile equals 5280 feet
Answer:
v = 22.5 miles/hour
Step-by-step explanation:
It is given that,
The speed of Penguins is 33 ft/s.
We need to convert the speed to miles per hour.
We know that, 1 mile = 5280 feet
Speed,
[tex]v=33\ \dfrac{ft}{s}\\\\=33\times \dfrac{\dfrac{1}{5280}\ \text{miles}}{\dfrac{1}{3600}\ \text{hour}}\\\\=22.5\ \text{miles/hour}[/tex]
So, the speed of the Penguins is 22.5 miles/hour.
