Answer:
2/3<9/10; I used 3/4 as a benchmark.
Step-by-step explanation:
2/3<1/2; I used 1/2 as a benchmark.
2/3 = 0.(20/3) = 0.667
1/2 = 0.(10/2) = 0.5
So this is wrong, as 0.667 > 0.5.
1/2=3/5; I used 1/4 as a benchmark.
1/2 = 0.(10/2) = 0.5
3/5 = 0.(30/5) = 0.6
0.5 != 0.6, so this is wrong.
2/3<9/10; I used 3/4 as a benchmark.
2/3 = 0.(20/3) = 0.667
9/10 = 0.(90/10) = 0.9
So this is correct, as 0.667 < 0.9
3/4<2/3; I used 1/2 as a benchmark.
3/4 = 0.(30/4) = 0.75
2/3 = 0.(20/3) = 0.667
0.75 > 0.667, so this is wrong.

Answer:
The slope is 1. It is the number before the x. If we do not see a number, we assume that the number is 1.
Step-by-step explanation:
Answer:
The slope: 1
Step-by-step explanation:
The slope is simply the number in front of the x ONLY in the form y=mx+b, which it is currently in. If it is not in that form, try and manipulate the equation to put it into that form.
Moreover, if it is just x by itself imagine there being a 1 in front of it.

Above are two different models of the same rectangular dog run. If the area of the model on the left is 54 sq cm, what is the area of the model on the right?
Answer:
48 sq cm
Step-by-step explanation:
The smaller square is 3' x 3' = 9 square feet.
The larger square is 9' x 9' = 81 square feet.
9 goes into 81 exactly 9 times (81 / 9 = 9), so we could just multiply the 54 cm by 9 and get your answer in centimetres.
54 x 9 = 486 cm

Maria makes a fruit salad. The table shows the amounts of different kinds of fruit that she uses. Kind of Fruit Amount Grapes 3 2/3 cups Melon 2 1/4 cups Pineapple 23/4 cups Strawberries? The amount of strawberries that Maria uses is 3/8 times the amount of the other fruits combined. How many cups of strawberries does Maria use?
Proportionately, the number of cups of strawberries that Maria needs to use is 3¹/₈ cups.
What is proportion?Proportion refers to a part of a whole.
Proportion is a ratio of one value to another.
Proportions are depicted as decimals, fractions, or percentages.
In this situation, we know that the amount of strawberries is a fractional value of the combined fruits.
Thus, we can multiply the fraction of strawberries against the combined value of the other fruits to determine the number of cups of strawberries needed.
Kind of Fruit Amount
Grapes 3²/₃ cups
Melon 2¹/₄ cups
Pineapple 2³/₄ cups
Total of other fruits = 8²/₃ cups
Strawberries ?
Strawberries = 3¹/₈ (8²/₃ x ³/₈)
Thus, Maria needs 3¹/₈ cups of strawberries.

C) 180°

Very confused, if you could please explain it to me, that would be great!!
The sum of the exterior angles for a parallelogram is 360°.
What is exterior angle?Exterior angles are angles that are formed outside two lines when they intersect. They are located outside the two lines, on the outside of the shape. They can be found by adding the two interior angles together, whose measurements are always equal to 180 degrees. Exterior angles are also supplementary angles, meaning that the sum of their measurements is always equal to 360 degrees.
This is because the four angles on the outside of the parallelogram are all right angles, and the sum of four right angles is 360°.
Similarly, the sum of the exterior angles for a hexagon is also 360°.
This is because the six angles on the outside of the hexagon are all 120° angles, and the sum of six 120° angles is 360°.

(URGENT) lWhich pair of functions are inverses of each other?
If the two graphs are mirror images of one another across the line y = x, then they are inverse functions.[tex]$f(x)=\frac{x}{3}+10$ \\[/tex] and [tex]$g(x)=3 x-10$[/tex]
How do you find a pair of inverse functions?As for looking at the graphs, we already knew that. You should keep in mind that inverse functions are represented by two graphs that are mirror images of one another over the line y = x. The broadest definition of an inverse function is one that "reverses" another function.
The inverse, for instance, must take b to an if a function goes from a to b. When the first and second elements of each pair in the original function are switched, a set of ordered pairs is obtained that is known as the inverse of the function. The act of switching the x and y coordinates is known as obtaining an inverse. They aren't opposites. The output of the first function is sent through an inverse function, which then generates an output whose input was the first function.
So, option A) [tex]$f(x)=\frac{x}{3}+10$ \\[/tex] and [tex]$g(x)=3 x-10$[/tex] is the appropriate response.

Sum of the measures of the interior angles of a polygon
For an n-sided polygon:

The heights of American men aged 18 to 24 are approximately Normally distributed with a mean of 68 inches and a standard deviation of 2.5 inches. About what percentage of the men are over 70.5 inches tall?
a ----2.5
b-----68
c-----16
d----5
e-----32
Answer:
Step-by-step explanation:
To find the percentage of men who are over 70.5 inches tall, we need to use the standard normal distribution table, which gives the proportion of observations that fall within a given range of standard deviation from the mean.
We first need to standardize the height of 70.5 inches by subtracting the mean (68 inches) and dividing by the standard deviation (2.5 inches) to get (70.5 - 68) / 2.5 = 0.8
This tells us that 70.5 inches is 0.8 standard deviations above the mean.
We can then look up the proportion of observations that fall within this range in the standard normal distribution table, which is approximately 0.1587 or 15.87%. So, the answer is (1-0.1587) = 84.13 or 84.13%.
So the answer is 84.13%

Step-by-step explanation: To solve f(x), g(x), or f(g(x)) problems, we place the value of x in the functions with the value that we are given. This value will be f(g(5)) or g(3) or f(27). We plug in the number in the parentheses.
In this problem, we have to first plugin 5 to g(x) then plug g(5) into f(x).
First, we do g(5)=sqrt((5^2)+2). This gives us 3. Then we plug in 3 which is g(5) into f(x). This gives us f(g(5)) or f(3)=sqrt((3^3)-2) which is 5.
Find the exact circumference of each circle

What is Circle’s Circumference?The diameter of a circle, also known as its circumference or perimeter, is the measurement of the circle's edge. As opposed to this, a circle's area indicates the space it occupies. The circumference of a circle is its length when we cut it open and draw a straight line from it. Units like centimeters or meters are typically used to measure it.The circle's radius is taken into consideration when applying the formula to determine the circumference of the circle. Therefore, in order to calculate the circumference of a circle, we must know its radius or diameter.The perimeter (or circumference) of a circle is equal to two R.where,R denotes the circle's radius.
The mathematical constant has a value that is around 3.14 (to the nearest two decimal places).Again,
As the ratio of any circle's circumference to diameter, pi () is a unique mathematical constant.and C = D
C represents a circle's circumference.D represents the circle's diameter.Calculate the circle's circumference, for instance, if its radius is 4 cm.Radius is given as 4 cm.Circumference = 2r
