Compare 7/8 with 14/16 using (<,>,=)

Answers

The correct answer is 7/8=14/16

7/8 already reduced to lowest terms, numerator and denominator have no common prime factors, So if you reduce 14/16 it simplifies to 7/8. 

The required 7/8 is equal to 14/16, or we can write 7/8 = 14/16.

What is simplification?

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.

Here,
To compare 7/8 and 14/16, we can first convert both fractions to a common denominator. The least common multiple of 8 and 16 is 16, so we can convert 7/8 to 14/16 by multiplying both the numerator and denominator of 7/8 by 2,

7/8 = (7 × 2) / (8 × 2) = 14/16

Now we can see that both fractions have the same denominator, so we can compare their numerators directly:

7/8 = 14/16

Therefore, 7/8 is equal to 14/16, or we can write 7/8 = 14/16.

Final answer:

To evaluate the expression a³ - b/c for a = 3, b = 2, and c = 4, substitute the values and simplify to get 27 - 1/2, which equals 53/2 in simplest form.

Explanation:

To evaluate the expression a³ - b/c when a = 3, b = 2, and c = 4, you need to substitute these values into the expression and simplify.

Step 1: Substitute the given values. The expression becomes 3³ - 2/4.

Step 2: Calculate the power of 3. The expression is now 27 - 2/4.

Step 3: Simplify the fraction 2/4, which is equivalent to 1/2.

Step 4: The expression now reads 27 - 1/2.

Step 5: To subtract, convert 27 to a fraction which has the same denominator as 1/2. This gives us 54/2 - 1/2.

Step 6: Subtract the fractions which results in 53/2, which is the simplest form.

Cindy has 26 nickels. She is getting rolls of nickels from the bank. She has enough money to get up to 10 rolls of nickels and each roll contains 40 nickels. The bank will not give partial rolls. The function that models the number of nickels Cindy will have after leaving the bank is f(r)=40r+26, where r is the number of rolls of nickels she gets.

We know that the domain is actually the number of rolls that she gets because it is the input variable in the equation  f (r) = 40 r + 26. The number of rolls that she can get can never be a negative number nor a zero nor a decimal number. However she can only get up to 10 rolls. Therefore the answer is:

Is this function even, odd, or neither?

Answers

when a function is even, they have symmetry with respect to the y-axis, what does that mean?  well, the graph to the right-side of the y-axis is just a mirror image of the graph to the left-side of the y-axis.

when a function is odd, the symmetry is with respect to the origin, meaning, the graph to the right-side of the y-axis, is a mirror image of the one on the left-bottom-upside-down.  So, you take a photo of the right-side graph,flip it over the x-axis, and then flip it again over the y-axis.

You can get some great new space for $23/square foot per year. You will be leasing 3,200 square feet. What will your MONTHLY rent be? a) $139 b) $3,200
c) $6,133 d) $73,600

Answers

since it is by square foot, and you are paying by square foot, just multiply the two numbers together

23 x 3200 = 73600

your answer is D) 73600

hope this helps
Final answer:

The calculation for the monthly rent involves firstly finding the annual rent by multiplying the cost per square foot per year with the total square footage, and then dividing this annual cost by 12 to get the monthly cost. The correct answer is c) $6,133.

Explanation:

To calculate the monthly rent, we first need to find out the annual rent and then divide it by 12 months. The annual rent can be found by multiplying the cost per square foot per year with the total number of square feet. So if the cost is $23/square foot per year and you are leasing 3,200 square feet, the calculation becomes: $23 * 3,200 = $73,600 for the annual rent. To calculate the monthly rent, we divide the annual rent by 12: $73,600 / 12 = $6,133.33. Therefore the monthly rent is closest to option c) $6,133.

Assume f(x) = g(x). Which of the following two functions may be used to represent the function 3x = x – 4? *
1 point
A) f(x) = 3x, g(x) = x – 4
B) f(x) = x – 7, g(x) = x – 4/3
C) f(x) = 3x, g(x) = 3x
D) f(x) = 7, g(x) = 3x

Answers

Since we know that the two functions are equal, f (x) = g (x), therefore when we equate the two equations the result should be similar to 3x = x – 4:

 

A. f(x) = 3x, g(x) = x – 4

Equating the two functions:

3x = x – 4             (correct)

Your classmate is unsure about how to use side lengths to determine the type of triangle. How would you explain this to your classmate?

Answers

1) Equilateral Triangles: These triangles have the same side length and same angle for all sides. Knowing this, if the side lengths given are all the same, the triangle will be classified as an equilateral triangle. 

2) Isosceles Triangles: These triangles have two sides that have the same side length and one that is not the same. Given this, if the side lengths are all given, the triangle with two same sides are classified as isosceles triangle. 

3) Scalene Triangles: These triangles have all sides associated with a different value. If all side lengths are given and they have different values, this triangle would classify as a scalene triangle. 

Hope I helped :) 

Answer:

First, look at the side lengths a, b, and c, where c is the longest. Then take the sum of a squared and b squared and compare it to c squared. If they are equal, the triangle is a right triangle. If c squared is less than a squared plus b squared, the triangle is acute. If c squared is greater than a squared plus b squared, the triangle is obtuse.

The sides of a triangular lot are represented by x, 3x, and 3x + 2. Find each side if the perimeter is 632 feet.

Answers

Perimeter of triangle is adding all three sides.
For example a triangle with sides 3, 5, and 7 would have a perimeter of 15

Now we use your values.

632 = (x) + (3x) + (3x + 2)
632 = 7X + 2
630 = 7x
90 = X

So side 1 is 90
Side 2 is 3(90) or 270
Side 3 is 3(90) + 2 or 272
Add all those up and you get (you guessed it) 632

(c) How long did it take the diver to reach the surface?

Need the answer A.S.A.P!

Answers

1. This problem lacks given values, where are the numbers? Just fill-in the numbers I will variables in this case.

Let us say that:

x = number of cups of flour

y = number of cups of white sugar

z = number of cups of brown sugar

(a) Just divide x by 6 to get cups of flour per serving

x / 6

(b) Simply add y and z and divide the sum by 6

(y + z)/6

(c) From (a) we know that there are x / 6 flours per serving, so simply multiply that by 9 then subtract the original x to know how much more you need:

[(x / 6) * 9] – x

 

2.

(a) We know that we deposit $5 per day, so after 5 days we got:

total deposit = ($5 / day) * 5 days = $25

(b) The total deposit is 25 dollars, so removing $2 a day we need:

25 / 2 = 12.5 days

 

3.

(a) d is distance, R is rate, T is time

32.12 = 8.8 T

(b) It is rightful to write distance d as a positive number since the scuba diver was ascending towards the surface. If this is to be plotted on a Cartesian plane, we are moving towards the positive y axis

(c) solving for T:

32.12 = 8.8 T

T = 32.12 / 8.8

T = 3.65 minutes

Hope this helps!

Answer:- (a/2, b) is coordinates should he assign to the third vertex of the isosceles triangle.


Explanation:-

As the given triangle is isosceles then the median of the triangle divides it into two equal triangles such that the base of the new triangles becomes half of the original triangle[tex]=\frac{1}{2}a[/tex]      

 [where a is the base of the original isosceles triangle]

Since the median of the given triangle join the third vertex and the mid point of the base thus the x coordinate of the points remains same[tex]=\frac{1}{2}a[/tex] and from the graph it is clear that y coordinate of third point is b .

Thus the coordinates for the third vertex must be [tex](\frac{a}{2},b)[/tex].

Which of these triangle pairs can be mapped to each other using a single reflection?

Answers

Answer:

The correct answer should be figure 1 which is also attached in the solution.

Step-by-step explanation:

Reflection of any object is the mirror image of the object about any line or plane. Reflection always shows a congruent figure but inverted.

In first figure, triangle EFG makes a mirror image as triangle FGL. Here, EG is equal to GL, EF is equal to FL and angle E is congruent to angle L.

So, the figure obtained is congruent and inverted. Thus, triangles can be mapped to each other in single reflection in this image.

Figure 2 shows two congruent triangles but the reflection is not a mirror image as it should be inverted.

Figure 3 shows two congruent triangles but here they are aligned in a similar manner and not inverted. So, it is incorrect.

Figure 4 has inverted and congruent triangles but the axis about which the image is taken doesn't match with them. While reflection, they will not overlap each other and hence, it is incorrect.

Therefore, the correct answer should be figure 1 which is also attached in the solution.
