\text{The sum of } 1\frac{7}{10}  \text{ and } 3\frac{3}{5} \text{ is } 5\frac{3}{10}

<em><u>Solution:</u></em>

Given that we have to find the sum of 1\frac{7}{10} \text{ and } 3\frac{3}{5}

<em><u>Let us first convert the mixed fractions to improper fractions</u></em>

Multiply the whole number part by the fraction's denominator.

Add that to the numerator.

Then write the result on top of the denominator

Therefore,

1\frac{7}{10} = \frac{10 \times 1 + 7}{10} = \frac{10+7}{10} = \frac{17}{10}\\\\3\frac{3}{5} = \frac{5 \times 3 + 3}{5} = \frac{18}{5}

Now we can add both the fractions

1\frac{7}{10} + 3\frac{3}{5} = \frac{17}{10} + \frac{18}{5}

Make the denominators same

1\frac{7}{10} + 3\frac{3}{5} = \frac{17}{10} + \frac{18 \times 2}{5 \times 2}\\\\1\frac{7}{10} + 3\frac{3}{5} = \frac{17}{10} + \frac{36}{10}\\\\\text{Add the fractions since the denominator is same }\\\\1\frac{7}{10} + 3\frac{3}{5} = \frac{17+36}{10} = \frac{53}{10}

Now convert the fraction to mixed number

When we divide 53 by 10 , the remainder is 3

Therefore, write 5 as a whole number and and 3 as numerator and 10 as denominator

\frac{53}{10} = 5\frac{3}{10}

Thus the sum of given mixed fraction is 5\frac{3}{10}

The perimeter of the base of the prism is __ units.
swat32

The bases of the prism are the triangular faces.

One side is marked 3 units. The vertical sides to the left of the triangles are 4 units. In a right triangle, if the legs measure 3 and 4, the hypotenuse measures 5.

The three sides of the triangular base measure 3, 4, and 5.

Perimeter = sum of the lengths of the sides

Perimeter = 3 + 4 + 5 = 12

Answer: 12 units

The table shows the grade that 4 students received on a math test. Find the bar graph that represents the grades.
tiny-mole [99]

Answer:

The answer to your question is the first graph.

Step-by-step explanation:

It seems that the first graph is correct because the height of the bars is equal to the grade get by the students.

The second graph is incorrect because the height of the bars is different from the grade the students got. Only the bar of Levi is correct.

The third graph is incorrect, just observe the height of John's bar to determine that the graph is wrong.

Also, the last graph is incorrect, in this graph, all the bars are different from the grade the students got.

If each side of a triangle measures 0.75 inches, what is the perimeter of the triangle?
mestny [16]

Answer:

0.75+0.75+0.75=2.25 inches

triangles are equal.So add 0.75 three times and write the answer as I mentioned. Also you must do it according to the book.I mean like,you adds it 3 times because triangle is 3 sided and it's a equilateral triangle.

Are you in Grade 8? bcoz me too.

btw I hope this helps you..
