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]

The surface area of a rectangular prism is 174 square inches. The rectangular base has one side length 3 times the other. The height of the prism is 5 inches. What are the maximum lengths of the sides of the base?
The maximum lengths of the sides of the rectangular base are approximately 7.616 inches and 22.847 inches.
How to find the maximum lengths of the sides of the baseThe surface area of the rectangular prism ([tex]A_{s}[/tex]) is equal to the product of two lengths of triangle. The area formula for the base is:
[tex]A = x\cdot (3\cdot x)[/tex]
[tex]A = 3\cdot x^{2}[/tex]
If we know that [tex]A = 174[/tex], then the least length of the base of the rectangle is:
[tex]x = \sqrt{\frac{A}{3} }[/tex]
[tex]x \approx 7.616\,in[/tex]

During the health check of a man of two weeks, it was observed that he had fever on 11 days, morning or evening. When he had fever in the evening, he had no fever in the morning. He had fever 9 days in the evening. How many days did he have no fever in the morning?
Step-by-step explanation:
2 weeks = 14 days.
on 11 days of these 14 he had fever.
that means on 14-11 = 3 days he did not have a fever.
on 9 of these 11 fever days he had the fever in the evening.
and we know, when he had fever in the evening, he had no fever in the morning.
so, the number of days without fever in the morning is :
9 + 3 = 12
as he had no fever in the morning when he had a fever in the evening, AND when he did not have any fever at all ...

Answer:
2 autos per hour
f(h) = 2h
Step-by-step explanation:
The graph in the interval 0 ≤ h ≤ 4 is a straight line through the origin, so represents a proportion. The constant of proportionality is the slope of the line, which is the ratio of vertical change to horizontal change.
On the interval [0, 4], we see that 8 automobiles are completed in 4 hours, so the slope is ...
(8 autos)/(4 hours) = 2 autos/hour
Then the completion rate function in that interval is ...
f(h) = 2h

If 50 percent of Q is 20 percent of P, then P is what percent of Q
Answer:
P is 250% of Q
Step-by-step explanation:
50/100 Q = 20/100P Multiply both sides by 100
50Q = 20 P Divide by 20
50/20 Q = P
2.5 Q = P
So P is 2.5 times the size of Q.
2.5 as a percent is 250 %

And since the symbol is greater than, we use a closed circle. Also, since the inequality is like an arrow pointing to the right, we draw the arrow going to the right.
Here are what the inequality symbols mean:
> = Greater than
≥ = Greater than or equal to
< = Less than
≤ = Less than or equal to
Open circles are used for numbers that are less than or greater than (< or >). Closed circles are used for numbers that are less than or equal to and greater than or equal to (≤ or ≥).
Mario has a fair coin. He conducts an experiment to determine how many times the coin lands on heads or tails. The results are shown in the table below.
Using Mario's experiment, what is the difference between the experimental and the theoretical probability that the fair coin lands on heads?
20%20 percent
30%30 percent
50%50 percent
70%
The difference that exist between the experimental and theoretical probability that the fair coin will lands on heads is A. 20%.
How to calculate probability?Your information is incomplete as the table isn't given. Therefore, an overview will be given.
It should be noted that theoretical probability describes how likely an event will occur. In this case, the probability of getting a head is 50%.Now, let's assume that the experimental probability that given is 70%.
In they case, the difference between the experimental and the theoretical probability that the fair coin lands on heads will be:
= 70% - 50%
= 20%
In conclusion, the correct option is 20%.

What is the x-intercept of the line 3x – 7y = 42?
PLEASE HELP
Answer: x-intercept = 42/3 = 14
Step-by-step explanation: y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
Notice that when x = 0 the value of y is 6/-1 so this line "cuts" the y axis at y=-6.00000
y-intercept = 42/-7 = 6/-1 = -6.00000
When y = 0 the value of x is 14/1 Our line therefore "cuts" the x axis at x=14.00000
x-intercept = 42/3 = 14
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -6.000 and for x=2.000, the value of y is -5.143. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -5.143 - (-6.000) = 0.857 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 0.857/2.000 = 0.429
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 3x-7y-42 = 0 and calculate its properties
x-intercept = 42/3 = 14

The missing length is the question mark on the top side.
Look at the bottom side. Its length is 10 yd.
Now look at the next horizontal side up from the bottom. Its length is 6 yd.
The missing length is the difference between 10 yd and 6 yd.

A group of friends wants to go to the amusement park. They have no more than $140 to spend on parking and admission. Parking is $5.75, and tickets cost $39.75 per person, including tax. What is the maximum number of people who can go to the amusement park?
Answer:
3
Step-by-step explanation:
Let the number of people be n.
39.75n + 5.75 ≤ 140
39.75n ≤ 134.25
n ≤ 3.37
The greatest integer less than or equal to 3.37 is 3.
Answer: 3
The maximum number of people who can go to the amusement park will be 3.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that the group has $140 to spend on parking and admission. Parking is $5.75, and tickets cost $39.75 per person, including tax.
For the inequality, we have to apply the arithmetic operation in which we do the multiplication of x and apply the inequality for the given data.
Suppose the number of people will be n.
39.75n + 5.75 ≤ 140
39.75n ≤ 134.25
n ≤ 3.37
The greatest integer value should be less than or equal to 3.37 is 3.
Thus, the maximum number of people who can go to the amusement park will be 3.

Qualitative answer. As x grows larger and larger, the contribute of lower degree terms (and constants) becomes irrelevant, and you rewrite everything picking the highest term for both numerator and denominator
[tex]\lim\limits_{x \to \infty} \frac{\sqrt{9x^4}}{x^2} $\lim\limits_{x \to \infty} \frac{3x^2}{x^2}=3[/tex]
Analitically.
Collect [tex]9x^4[/tex] in the numerator under the square root, [tex]x^2[/tex] in the denominator.
[tex]\lim\limits_{x \to \infty} \frac{\sqrt{9x^4(1+\frac{1}{9x^4})}}{x^2(1-\frac{3}{x}+\frac{5}{x^2})} = \lim\limits_{x \to \infty}\frac{3x^2\sqrt{(1+\frac{1}{9x^4})}}{{x^2(1-\frac{3}{x}+\frac{5}{x^2})}} = 3[/tex]
