Answer:

[tex]\frac{58}{35}[/tex] is the answer.

Step-by-step explanation:

1) Use this rule: [tex]\frac{a}{b} * c = \frac{ac}{b}[/tex]

[tex]\frac{4}{5} + \frac{3*2}{7}[/tex]

2) Simplify 3 * 2 to 6.

[tex]\frac{4}{5} + \frac{6}{7}[/tex]

3) Simplify.

[tex]\frac{58}{35}[/tex]

Therefor, the answer is 58/35 and if you need it on decimal form it would be, 1.657143.

Answer:

74.6

Step-by-step explanation:

The area of the given triangle in the image is 74.8m².

A triangle is simply a polygon with three vertices with three edges.

A scalene triangle is the triangle with no equal sides and angles.

It area can be calculated using the expression;

A = 1/2 × absinθ

Given the data in question;

To determine the area of the triangle, we substitute our given values into the expression above.

A = 1/2 × absinθ

A = 1/2 × 15m × 11m × sin( 115° )

A = 0.5 × 15m × 11m × 0.9063

A = 74.76975m²

A = 74.8m²

Therefore, the area of the given triangle in the image is 74.8m²

Answer:

105 , 245

Step-by-step explanation:

Ratio = 3 : 7

3x , 7x

3x + 7x = 350

         10x = 350

             x = 350/10

            x = 35

3x = 3*35 = 105

7x = 7 *35 = 245

Answer:

3

Step-by-step explanation:

2 times 1 is 2 and then multiply 1/2 by 2 and you'll get 1 then add those two numbers together and you will get 3.  Note: The best way to do these types of things in multiplication is to split the numbers up among the decimal places so if you did 15 times 4 then an easy way to do it would be to split the 15 with 10 and 5 so then multiply the 10 by 4 and you get 40 now do the same to the 5 and you get 20 so now add those two numbers together and you get 60(This has nothing to do with the answer i just want to help make it easier for future problems such as this).
