How are Ratios,rates and unit rates used to solve problems?

Answers

Answer 1

Answer:

hope u understand

Step-by-step explanation:

Unit rates can conveniently be multiplied by any desired number in order to answer questions about differently scaled questions. E.g. If three marbles cost 30 cents, how much will eleven marbles cost?

A unit rate is a ratio such as 30 cents : 3 marbles = 10 cents per (1) marble, after doing the division.

Answer 2

Answer:

ratios, rates, and unit rates can be used to solve how much of something there is compared to another thing.  Ex: There are 3 times the amount of apples compared to oranges.  How many apples are there if you have 2 oranges?  For a ratio, you would make it 3:1.  Then substitute the 1 for 2.  For a rate, you would make it 3 apples per oranges.  Then do the same thing you would do for the ratio.  Unit rates work the same way.

i had the same question

The number of possible ways can the chairs be lined up is 2 rows of 41.

Given that,

There are 82 chairs at a birthday party. The chairs need to be lined up in equal-sized rows.

Based on the above information, the calculation is as follows:

[tex]= 2 \times 41[/tex]

= 82 chairs

Here 2 denotes the rows.

Therefore we can conclude that the number of possible ways can the chairs be lined up is 2 rows of 41.

What is the vertex for the graph shown below?
a. (0,0)
b. v=1
c. v=5
d. (5,1)

Answers

Answer:

D. (5,1)

Step-by-step explanation:

The vertex of the graph is V ( 5 , 1 ).

Given data:

The vertex of a function is a point on the graph where the function reaches its highest or lowest point, depending on whether the function is concave up or concave down.

The vertex represents the minimum or maximum point of the function and provides information about the axis of symmetry of the graph. If the function opens upward (concave up), the vertex is the lowest point (minimum).

So, the highest point in the graph where the function reaches the minimum value is when x = 5

So, the value of y = 1

Hence , the vertex is V ( 5 , 1 ).

If f(x)=|x+7|, find f(−12).

Answers

Answer:

5

Step-by-step explanation:

insert f(-12) for f(x) and solve

f(-12)=|-12+7|

add -12 and 7

f(-12)=|-5|

absolute value makes it positive

f(-12)=5

If f(x)=|x+7|, the value of f(-12)=5

Given :

the function f(x)=|x+7|. Lets find out f(-12)

f(x) is an absolute function . Absolute function always gives us positive value .

for example |-6|=6

In f(-12) the value of x is -12

To find f(-12) we replace x  with -12 in f(x).

[tex]f(x)=|x+7|\\f(-12)=|-12+7|\\f(-12)=|-5|\\f(-12)=5[/tex]

so,  we got f(-12)=5

Determine whether or not the equation shows a proportional relationship. If it does, identify the unit rate (constant of proportionality).
y =25x, a = 5x + 5, m = 105.25n

Answers

Answer:

y = 25·x shows a proportional relationship

a = 5·x + 5 does not show a proportional relationship

m = 105.25·n shows a proportional relationship

Step-by-step explanation:

An equation that shows a proportional relationship is of the form, y = kx

Where;

k = The constant of proportionality = y/x

Therefore, the equation, y = 25·x shows a proportional relationship

The constant of proportionality = k = y/x = 25

Similarly, the equation m = 105.25·n shows a proportional relationship

The constant of proportionality = k = m/n = 105.25

When the equation shows a proportional relationship, the graph of the equation passes through the origin, therefore, the equation of the form, y = m·x + c, where c = the y-intercept > 0, the equation does not show a proportional relationship

The equation a = 5·x + 5, which is of the form, y = m·x + c, with c = 5 > 0, therefore, does not show a proportional relationship.

Therefore;

y = 25·x shows a proportional relationship

m = 105.25·n shows a proportional relationship

a = 5·x + 5 does not show a proportional relationship.

There is 1/2 of a greater chance in drawing a spade over drawing a 7

How to determine the probability?

From the complete question added as an attachment, we have the following parameters:

n(Spade) = 4n(7) = 1Total = 6

The probability of getting a spade is:

P(Spade) = 4/6

The probability of getting a 7 is:

P(7) = 1/6

The difference between both probabilities is:

Difference = 4/6 - 1/6

Evaluate

Difference = 3/6

Simplify

Difference = 1/2

Hence, there is 1/2 of a greater chance in drawing a spade over drawing a 7
