Hello!
Let's consider what the question asks for
--> value of 'y' when 'x = 0'
-7x + 3y = 30
Let's plug in '0' into x and solve for 'y'
[tex]-7x+3y=30\\\\-7(0)+3y=30\\\\y=10[/tex]
Thus y = 10 when x = 0
Answer: 10
We are given the equation:
[tex]\rm{-7x + 3y = 30}[/tex]To find the value of y when x equals 0, we need to substitute 0 for x in the equation and solve for y:
[tex]\rm{-7(0) + 3y = 30}[/tex]Simplifying the equation:
[tex]\rm{3y = 30}[/tex]Dividing both sides by 3:
[tex]\boxed{\rm{y = 10}}\quad\green{\checkmark}[/tex][tex]\blue{\overline{\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad}}[/tex]
If 7 notepads cost $4.55, what is the unit price of the notepads?
Answer:
[tex]0.65[/tex]
Step-by-step explanation:
Given the following question
7 notepads cost $4.55 what's the unit price?
Unit price is price per unit, we find the price per unit by dividing the total cost of the notepads by the total amount of the notepads which is 7.
[tex]unitp=cost\div quantity[/tex]
[tex]7n=4.55[/tex]

At the U.S. Open Tennis Championship a statistician keeps track of every serve that a player hits during the tournament. The statistician reported that the mean serve speed of a particular player was 100 miles per hourâ (mph) and the standard deviation of the serve speeds was 13 mph. If nothing is known about the shape of theâ distribution, give an interval that will contain the speeds of at least eight-ninths of theâ player's serves.
a. 74 mph to 126 mph
b. 61 mph to 139 mph
c. 48 mph to 152 mph
d. 139 mph to 178 mph
Answer:
b. 61 mph to 139 mph
Step-by-step explanation:
Chebyshev's theorem states that
For k> 1
1 - 1/k²
Where:
At least 75% or 3/4 of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.
At least 88.89% of 8/9 of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.
From the question, we are told to find an interval that will contain the speeds of at least eight-ninths of the player's serves.
Mean (μ)= 100mph
Standard deviation (σ) = 13mph
At least 88.89% of 8/9 of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.
Hence:
μ - 3σ
100 - 3(13)
= 100 - 39
= 61 mph
μ + 3σ
= 100 + 3(13)
= 100 + 39
= 139 mph
Therefore, the interval is between 61 mph to 139 mph. Option b is correct

The temperature of a cup of coffee varies according to Newton's Law of Cooling: dT dt equals negative k times the quantity T minus A, where T is the temperature of the coffee, A is the room temperature, and k is a positive constant. If the coffee cools from 100°C to 90°C in 1 minute at a room temperature of 25°C, find the temperature, to the nearest degree Celsius of the coffee after 4 minutes.
74

60
42
Answer:
67.3°C
Step-by-step explanation:
A = 25, T(0) = 100, T(1) = 90, find T(4)
dT/dt = -k(T - A)
d(T - A)/dt = -k(T - A)
d(T - A)/(T - A) = -k dt
ln(T - A) = lnC - kt
[tex]T(t) -A=Ce^{-kt}\\T(t) = A + Ce^{-kt} = 25 + Ce^{-kt}\\T(0) = 25 + C = 100\\C=75[/tex]
[tex]T(t) = 25 + 75e^{-kt}\\T(1) = 25 + 75e^{-k} = 90\\75e^{-k} = 65\\e^{-k} = \frac{65}{75}, k = ln\frac{75}{65} = 0.1431\\T(t) = 25+75e^{-0.1431t}\\T(4) = 25+75e^{-0.1431\times4} = 67.3[/tex]

QUICK PLZZZZ. |n-3|=5 solve the equation
Answer:
Step-by-step explanation:
-31 cannot equal 5 so the equation is false.
Answer:
n=8
Step-by-step explanation:
So, |n-3| means that the expression, n-3, is an absolute number (which is the difference from zero; just take off the negative sign if it has one)
Because the left side of the equation, 5, is a positive number, you would know that the equation can be solved by:
n-3=5 add 3 to both sides
n=8
You should also know that the absolute number (shown using | |) is not a negative number. (well, as long as the n is a real number)

A group of students went on a field trip. There were 3 boys for every 4 girls in the group. If there were 20 girls, how many students in all went on the field trip?
Answer:
35 students
Step-by-step explanation:
So if every 3 boys there is 4 girls you can solve that there is 5 times the amount of girls to get to 20. So to solve for the boys you do the same.
3 x 5 = 15
That means there are 15 boys and 20 girls but we want to know the total so what you do is just add 15+20=35
So 35 total students.

Which fraction is equivalent to 5/12 + 2/3
Answer:
5/12 + 8/12 = 13/12 = 1 1/12
Step-by-step explanation:
This is the answer because:
1) You have to add the fractions, in order to add the fractions you have to find the common denominato.
2) The common denominato is 12 because 2 x 4 = 8 and 3 x 4 = 12. Therefore, 2/3 = 8/12.
3) Finally, once you add 5/12 and 8/12, you should get 13/12 which is also equal to 1 1/12.

A large wooden box, as shown, has a volume of 4352 ft3. The box is a right square prism with a base with sides that each measure 16 ft. What is h, the height of the box?
To find the volume of a prism, we can use the following formula:
[tex]V=base\hspace{3}area*height[/tex]
Although this formula is typically used to find the volume of a prism, we can also use it to find the base area or height, as long as we re-arrange it accordingly.
For a rectangular prism, the base area is solved using the following formula:
[tex]A=lw[/tex] ⇒ where l is the length and w is the width
Solving the QuestionWe're given:
V = 4352 ft³l = 16 ftw = 16 ftWe need to solve for the height of the box.First, find the base area:
[tex]A=lw\\A=16^2\\A=256[/tex]
Therefore, the base area is equal to 256 ft².
Now, modify the volume formula to isolate the height:
[tex]V=base\hspace{3}area*height[/tex]
⇒ Divide both sides by the base area:
[tex]\dfrac{V}{base\hspace{3}area}=\dfrac{base\hspace{3}area*height}{base\hspace{3}area}\\\\\dfrac{V}{base\hspace{3}area}=height\\\\height=\dfrac{V}{base\hspace{3}area}[/tex]
⇒ Plug in the given values:
[tex]height=\dfrac{4352}{256}\\\\height=17[/tex]
Therefore, the height of the box is 17 ft.
AnswerThe height of the box is 17 ft.

Which graph represents the following system of inequalities? y < -3x+5 y < x+2 y < -1
Answer:
The attached graph represents the system
Step-by-step explanation:
Let us describe the graph of each line
In y < -3x + 5
∵ The sign of inequality without =
∴ The line represents it must be dashed
The slope-intercept form of the inequality is y < m x + b, where m is the slope and b is the y-intercept
∵ y < -3x + 5
∴ m = -3 and b = 5
∴ The direction of the line is to the left and intersect the y-axis at (0, 5)
∴ y < -3x + 5 represented by the green line
∵ The sign of inequality is <, then the shading is under the green line
In y < x + 2
∵ The sign of inequality without =
∴ The line represents it must be dashed
∴ m = 1 and b = 2
∴ The direction of the line is to the right and intersect the y-axis at (0, 2)
∴ y < x + 2 represented by the blue line
∵ The sign of inequality is <, then the shading is under the blue line
In y < -1
∵ The sign of inequality without =
∴ The line represents it must be dashed
∴ m = 0 and b = -1
∴ The line is horizontal and intersects the y-axis at (0, -1)
∴ y < -1 represented by the red line
∵ The sign of inequality is <, then the shading is under the red line
∵ The shading of the three inequalities is under the lines
∴ The solutions of the system of inequalities lie in the common
shaded part under the three lines
∴ The attached graph represents the system

Answer:
1.333
Step-by-step explanation:
Distance travelled (or displacement) will be the antiderivative of Velocity.
Antiderivative of -t^2 + 2 =
d(t) = -t^3/3 +2t
Now plug in t=2 and t=0 and subtract them.
(-8/3+4)- (0/3 +0)= -8/3+4 = 1.333
Answer:
1.333
Step-by-step explanation:
We know that the displacement function is the integral of the velocity function. We are also given our bounds, 0 seconds to 2 seconds.
x(t) = [tex]\int\limits^2_0 {t^{2} +2} \, dt[/tex] = -t³/3 + 2t (evaluated from zero to two)
= [-2³/3 + 2(2)] - [-0³/3 + 2(0)] = 4/3 = 1.333...
