The diametric size of cell H is 3.86 times larger the diametric size of cell K.
How is a ratio determined?
Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. A ratio is a comparison or condensed version of two quantities of the same type. We may determine how many times one quantity is equal to another using this relationship. The ratio can be defined as the number that can be used to represent one quantity as a percentage of another.
Given, the diametric size of cell H, say y = 3.52×10⁻³ cm
The diametric size of cell K, say x = 9.1×10⁻⁴ cm = 0.91×10⁻³ cm
The ratio of the diametric size of H to K, y/x = 3.52×10⁻³/0.91×10⁻³ = 3.86
Thus, y = 3.86x, the diametric size of cell H is 3.86 times the diametric size of cell K.

What is the area of this trapezoid 13 cm 15cm 29cm
Answer:315
Step-by-step explanation:
Suppose a shipment of 150 electronic components contains 4 defective components. To determine whether the
shipment should be accepted, a quality-control engineer randomly selects 4 of the components and tests them. If 1 or
more of the components is defective, the shipment is rejected. What is the probability that the shipment is rejected?
The probability that the shipment will be rejected is 2/75.
What is probability?The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a proposition to be true. A number between 0 and 1 is the probability of an event, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes its certainty. Simply put, probability measures how likely something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. is the study of events subject to probability.So, the probability that the shipment is rejected:
Probability formula: P(E) = Favourable events/Total events.Where favorable events are 4 and total events are 150.Now, substitute the values in the formula and solve as follows:
P(E) = Favourable events/Total eventsP(E) = 4/150P(E) = 2/75Therefore the probability that the shipment will be rejected is 2/75.

A parasail is $\frac{3}{100}$
mile above the water. After 5 minutes, the parasail is $\frac{1}{50}$
mile above the water. Find the change in height of the parasail.
The change is height is
mile.
The change in height of the parasail = 1/100
What is height?Height of defined as the measurement that is taken for an object which starts from its base to the topmost point. This is usually measured in meters.
From the question,
The height of the parasail above the water level= 3/100
The height of the parasail above the water level after 5 minutes= 1/50
The change in height of the parasail is determined by finding the difference between the two heights.
That is, = 3/100 - 1/50
= 0.03- 0.02 = 0.01
When changed to fraction is = 1/100

Answer:
The second option: f(x) = -(200/x)
Step-by-step explanation:
We can see that the input of the function is 20 and the output is -10. For the inverse, these values will swap: -10 will be the input and 20 will be the output.
Given that, we can substitute -10 into each equation and use trial and error to find out which one gives 20 as the output.
The first one, f(x) = -(0.5/x) will give an output of -(0.5/-10) = 1/20, which is incorrect.
The second one, f(x) = -(200/x) will give an output of -(200/-10) = 20, which is correct. Therefore, this must be the inverse. There will only be one inverse, so we don't need to try the rest.

(-1, 9) \text{ and } (4, -3)
(−1,9) and (4,−3)
The distance between the given points will be 13 square units.
A triangle may be defined as a closed figure having three sides and three interior angles. A right triangle may be defined as a triangle which has one interior angle as 90°. The right triangle consists of a base, an altitude and a hypotenuse. We have the coordinates of the hypotenuse as (-1, 9) and (4, -3). If we plot these points on graph paper, we get the other point as (-1, -3). Also, the distance between the points (-1. 9) and (4, -3) is given by
Distance = √(-3 - 9)² + (4 + 1)²
Distance = √(-12)² + (5)²
Distance = √144 + 25
Distance = √169

Mr. Fillbach will be able to have orange juice before having to buy more juice for 16 mornings.
The gallon is a unit of volume in imperial units and us a customary device. 3 one-of-a-kind variations are in modern use: the imperial gallon.
A clean manner to discern from liters to gallons, for an instance, is that a quart is a bit much less than a liter and 4 liters is a touch extra than 1 gallon. To be specific, 1 liter is 0.264 gallons (a bit greater than a quart), and four liters is 1.06 gallons. Q-I need to shop for a 35 mm. A gallon is equal to approximately 3.78541 liters. consequently, a gallon is larger than 3 liters.
Cups and liters each measure the extent of beverages, so whether or not you need to know how many cups are in a liter or water, oil or a bottle of soda, there will constantly be approximately four.3 cups in a liter! The liter is a metric measurement closest to the quart in imperial measurements.

The line with m as the slope, and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.
The slope, m, is a measure of how steep a line is. Sometimes, the gradient of a line is referred to as its slope. A line's y-intercept, ab, denotes the y-coordinate of the location where the line's graph crosses the y-axis.
Given, the first equation is 5x - 6y = 30

Answer:
x = $3.5
y = $2.25
z = $1.5
Step-by-step explanation:
let x = price of a hotdog
y = price of a drink
z = price of a pretzel
according to the question:
Davis family spends: 3x+2y+z = $16.50 (equation 1)
Ruiz family spends: 4x+4y+2z = $26 (equation 2)
Cho family spends: 2x+y+3z = $13.75 (equation 3)
from eq. 1
z = 16.50-3x-2y
substituting in eq.2
4x+4y+2(16.50-3x-2y) = 26
4x+4y+33-6x-4y=26
-2x=26-33
thus x = $3.5
from eq. 3
y = 13.75-2x-3z
y = 13.75-2(3.5)-3z
y = 13.75-7-3z
y=6.75-3z
thus,
z = 16.50-3(3.5)-2(6.75-3z)
z = 16.50-10.5-13.5+6z
z-6z = -7.5
-5z = -7.5
thus z = $1.5
thus
y = 6.75-3(1.5)
y = $2.25

The solution of the inequality is x ≤ 3 or x > 18.
An inequality in mathematics is a relation that compares binary number or other mathematical in an unequal way.
The majority of the time, size comparisons between two figures on the number line are made. Different types of inequalities are represented by a variety of notations . The symbol for "larger than" that is divided in half by the word "not" can also be used to denote the relationship not greater than. For not fewer than and and a b, the same holds true.Now let us solve the inequality:
6x - 10 ≤ 8
adding 10 on both sides:
or, 6x -10+10 ≤ 8+10
or, 6x ≤ 18
dividing both sides by 6 we get :
or, 6x ÷ 6 ≤ 18 ÷ 6
or, x ≤ 3
For the second inequality:
1/3x+6>12
subtracting 6 from both sides :
or, 1/3x+6 - 6 > 12 - 6
or, 1/3 x > 6
Multiplying both sides by 3
or, x > 18
Therefore the complete solution is x ≤ 3 or x > 18 .
