1. Determine the variables in the figure below. 20 50

Mathematics
1 answer:
Marina CMI [18]3 years ago
7 0

Answer:

r=8

t=4√29

Step-by-step explanation:

By the altitude leg theorem:

{20}^{2}  = 50r

This implies that:

r =  \frac{20 \times 20}{50}

We simplify to obtain:

r = 4 \times 2 = 8

By the Pythagoras theorem:

{t}^{2}  =  {20}^{2}  +  {8}^{2}

{t}^{2}  = 400 + 64

{t}^{2}  = 464

t =  \sqrt{464}

t = 4 \sqrt{29}

A scuba diver starts at 85 3/4 meters below the surface of the water and descends until he reaches 103 1/5
RSB [31]

Answer:

From his starting point of 85 3/4, he descended 17 9/20 meters

Step-by-step explanation:

We want to know how much farther he went down from his starting point.

103 1/5 - 85 3/4

S

tart off by making the denominators of both the numbers the same.

103 1/5 - 85 3/4

103 4/20 - 85 15/20

Make them into improper fractions

2064/20 - 1715/20 = 349/20

Make 349/20 into a mixed fraction

17 9/20
