Brittany went grocery shopping , she spent 4/7 of her money on fresh foods. she spent 2/3 of the remainder of her money on froze

pychu [463]

Answer:

$44

Step-by-step explanation:

Let the total amount of money be represented by Y

Amount spent on fresh food =

$\frac{4}{7} \times y$

Remainder =

$y - \frac{4}{7}y = \frac{3}{7} y$

Amount spent on frozen foods = two-thirds of remainder = $22

$= \frac{2}{3} \times \frac{3}{7} y = \frac{2}{7} y$

$\frac{2}{7} y = 22 \\ y = 22 \times \frac{7}{2} \\ y = 77$

The total amount for grocery shopping is $77

Therefore, Brittany spent $44 on fresh foods

$= \frac{4}{7} \times 77 \\ = 4 \times 11 \\ = 44$

Given right triangle XYZ, which correctly describes the

Ymorist [56]

Answer:

a is adjacent, b is opposite, c is the hypotenuse

Step-by-step explanation:

A right angled triangle must contain the opposite, the adjacent and the hypotenuse. The opposite is the side that directly faces the angle of interest. The adjacent is the side that is close to the angle of interest.

Given that the angle Y is positioned between X and Z, the point b becomes the opposite of Y. The point a becomes adjacent to angle Y while c remains the hypotenuse of the right angled triangle.

The image below typifies the explanation given above. It shows the relationship between the three sides of the right angled triangle in detail.
