Omar's gas tank is 1/10 full. After he buys 6 gallons of gas, it is 2/5 full. How many gallons can Omar's tank hold?
castortr0y [4]
1/10x + 6 = 2/5x
6 = 2/5x - 1/10x
6 = 4/10x - 1/10x
6 = 3/10x
6 / (3/10) = x
6 * 10/3 = x
60/3 = x
20 = x <=== the gas tank can hold 20 gallons

Shapes A and B are similar.
kari74 [83]

The scale factor from A to B is 5/3 and the value of r is 33/5

<h3>The scale factor from A to B</h3>

From the figure, we have the following corresponding sides

A : B = 5 : 3

Express as fraction

B/A = 3/5

This means that, the scale factor from A to B is 5/3

<h3>The value of r</h3>

From the figure, we have the following corresponding sides

A : B = 11 : r

Express as fraction

B/A = r/11

Recall that:

B/A = 3/5

So, we have:

3/5 = r/11

Multiply by 11

r = 33/5

Hence, the value of r is 33/5

Write an equation for this situation.
kirza4 [7]
Answer: A) y = 3x + 2

Step-by-Step Explanation:

Let ‘y’ be the total no. of books he read

Given:

He read 2 books before joining (+2)
He plans to read 3 books per month (3x)

Equation:

= Total no. of books = 3 multiplied by the no. of months + 2 books he had read

WILL MARK AS BRAINIEST!!!!!!! In this triangle, which of the following is true?
prisoha [69]

Answer:

D

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 given angles from 180

x = 180° - (90 + 35)° = 180° - 125° = 55°

----------------------------------------------------------

Since the triangle is right use the cosine ratio to solve for b

cos35° = \frac{adjacent}{hypotenuse} = \frac{b}{20}

Multiply both sides by 20

20 × cos35° = b, hence

b = 16.38 ( to 2 dec. places )
