You just add the two lengths and then do pythagorean theory to get the length of the hypotenuse. Then you add them all together to get 18.8. Hope this helps.

A colored chip is yellow on one side and red on the other. The chip was flipped 50 times and landed on red side up 22 times. Wha

AnnZ [28]

Answer:

The correct answer is:

44% (B.)

Step-by-step explanation:

number of times flipped = 50 times

number of times red landed face-up = 22 times

∴ frequency of chip landing with red side face up = (number of times red landed face-up) ÷ (number of times flipped) × 100

= (22 ÷ 50) × 100 = 44%

If 2/3 of the distance from the y-axis to point A (−30, −45) is equal to 1/4 of the distance from the x-axis to point B(5a, 2a),

Aliun [14]

Answer:

The value of a is 80

Step-by-step explanation:

The distance of a point $(x_o,y_0)$ from the y-axis can be written as $d_y=|x_o|$ because the x-coordinate of the y-axis is zero.

Similarly, the distance of a point from the x-axis can be written as $d_x=|y_0|$

since the y-coordinate of the x-axis is zero.

In this problem:

- The distance of the point A (−30, −45) from the y-axis can be written as

$d_A=|-30|=30$

- The distance of point B (5a,2a) from the x-axis can be written as

$d_B=|2a|=2a$

Since $a>0$

We are told that 2/3 of the distance from the y-axis to point A (−30, −45) is equal to 1/4 of the distance from the x-axis to point B(a, a), which means

$\frac{2}{3}d_A=\frac{1}{4}d_B$
