This diagram shows three small squares and two rectangles composed of 10 small squares, Jade says this diagram can represent 230. What does a small square represent for Jada? Name a number greater than 230 that can also represent.
Lin says this diagram can represent 2.3, what does a small square represent for Lin. Name a number of less than 2.3 that this diagram can also represent.
Answer:
Step-by-step explanation:
From the figure
A small square represents 10 for Jade's diagramA small square represents 1 for Lin's diagramFrom the figure, we have:
Rectangles = 2 (20 squares)
Square = 3
Represent 1 square with x.
So, the number is represented as:
[tex]Number = 20x + 3x[/tex]
[tex]Number = 23x[/tex]
Jade says the number represents 230.
So, we have:
[tex]23x = 230[/tex]
Divide through by 23
[tex]x = 10[/tex]
This means that:
A small square represents 10 for Jade's diagram
Lin says the number represents 23.
So, we have:
[tex]23x = 23[/tex]
Divide through by 23
[tex]x = 1[/tex]
This means that:
A small square represents 1 for Lin's diagram

Can you ever have a function and a relation at the same time? Why or why not?
Answer: If you think of the relationship between two quantities, you can think of this relationship in terms of an input/output machine. If there is only one output for every input, you have a function. If not, you have a relation. You can conclude that this set of ordered pairs does not represent a function

What is 6 3/4 divided by 2 5/8?
Conversion a mixed number 6 3/4 to a improper fraction: 6 3/4 = 6 3/4 = 6 · 4 + 3/4 = 24 + 3/4 = 27/4.
To find new numerator:
Multiply the whole number 6 by the denominator 4. Whole number 6 equally 6 * 4/4 = 24/4
Add the answer from previous step 24 to the numerator 3. New numerator is 24 + 3 = 27
Write a previous answer (new numerator 27) over the denominator 4.
Six and three quarters is twenty-seven quarters
Conversion a mixed number 2 5/8
to a improper fraction: 2 5/8 = 2 5/8 = 2 · 8 + 5/8 = 16 + 5/8 = 21/8
To find new numerator:
Multiply the whole number 2 by the denominator 8. Whole number 2 equally 2 * 8/8 = 16/8
Add the answer from previous step 16 to the numerator 5. New numerator is 16 + 5 = 21.
Write a previous answer (new numerator 21) over the denominator 8.
Two and five eighths is twenty-one eighths
Divide: 27/4 : 21/8 = 27/4 · 8/21 = 27 · 8/4 · 21 = 216/84 = 12 · 18 /12 · 7 = 18/7
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 21/
8 is 8/21) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step , cancel by a common factor of 12 gives 18/7.
In words - twenty-seven quarters divided by twenty-one eighths = eighteen sevenths.
The solution of the expression [tex]6 \dfrac{3}{4}[/tex] divided by [tex]2 \dfrac{5}{8}[/tex] , which are in mixed fraction is [tex]\dfrac{18}{7}[/tex]
A collection of constants, variables connected using one or more arithmetic operator is called an expression.
The combination of a whole number and a proper fraction is called as mixed fraction.
The following expression can be simplified as:
Here, both the fraction are converted into improper fraction as[tex]\dfrac{27}{4}[/tex] and, [tex]\dfrac{21}{8}[/tex]
Now, the following expression is simplified as:
[tex]\dfrac{\dfrac{27}{4}}{\dfrac{21}{8}}[/tex],
Reciprocal the expression, so that the division sign changes to multiplication.
[tex]\dfrac{27}{4} \times \dfrac{8}{21}[/tex]
Thus, the solution will be [tex]\dfrac{18}{7}[/tex].

explain how to make these couculations mentaly a. 99+54 b.244-99
PLEASE MARK BRAINLIEST!
Answer:
Use estimation
Step-by-step explanation:
A) 99 + 54
estimate that 99 is 100
estimate that 54 is 55
Add 100 and 55 together
100 + 55 = 155
Remember that you added 1 to 99 and 1 to 55
So you must subtract 2 from 155
155 - 2 = 153
Your answer is 153.
B) 244 - 99
estimate that 244 is 245
estimate that 99 is 100
Add 245 and 100 together
245 + 100 = 345
Remember that you added 1 to 245 and 1 to 99
So you must subtract 2 from 345
345 - 2 = 343
Your answer is 343.
Remember that you are doing all of this in your head!
