A deep sea driver descended from a rock with an elevation of -45.5 feet to a coral reef with an elevation of -88.5 feet. How far

vlada-n [284]

Answer:

43 feet

Step-by-step explanation:

How far is referring to the distance between the two numbers given.

In general, the distance between two numbers, a and b,

is given by |b-a| .

You have that you are finding the distance between -45.5 ft and -88.5 ft.

So the distance between those numbers is given by:

|-45.5-(-88.5)|

|-45.5+88.5|

|88.5-45.5|

|43.0|

|43|

43 (Since the number inside the | | has a distance of 43 from 0)

The distance between -45.5 ft and -88.5 ft is 43 ft.

Exercise 1: In the right triangle below, calculate the measurement of the unknown side. Show your work.

vekshin1

Answer:

Exercise 1:

base [b]=8cm

perpendicular [p]=6cm

hypotenuse [h]=?

By using Pythagoras law

h²=p²+b²

h²=6²+8²

h=√100

h=10cm

So another side's length is 10cm

Exercise 2:

base [b]=6m

perpendicular [p]=bm

hypotenuse [h]=8m

By using Pythagoras law

h²=p²+b²

8²=b²+6²

b²=8²-6²

b=√28=2√7 0r 5.29 or 5.3

So height of kite is√28or 2√7 0r 5.29 or 5.3 m

. Laura and Alicia both exercise 5 days a week. Laura exercises for 30 minutes each day. Alicia exercises for 45 minutes each da

statuscvo [17]

Answer: 1 hour 15 minutes

Step-by-step explanation:

From the question, we are informed that Laura and Alicia both exercise 5 days a week and that Laura exercises for 30 minutes each day. For the 5 days, she'll exercise for:

= 5 × 30 minutes

= 150 minutes

= 2 hours 30 minutes

Alicia exercises for 45 minutes each day. Fir the 5 days, she'll exercise for:

= 5 × 45 minutes

= 225 minutes

= 3 hours 45 minutes

We then calculate the difference in their exercise per week which will be:

= 3 hours 45 minutes - 2 hours 30 minutes

= 1 hour 15 minutes

Consider vectors u and v, where u = (1, -1) and v = (1, 1). What is the measure of the angle between the vectors?

7nadin3 [17]

Answer:

I believe the answer is C. 90 degrees

Step-by-step explanation:

First you find the lengths of the two vectors, which are both $\sqrt{2}$ . Then you find the angle given the cos using: cos(∅)= $\frac{u*v}{|u|*|v|}$ = $\frac{0}{\sqrt{2}*\sqrt{2} }$ = 0. Then using ∅=acos(0)= $\frac{\pi }{2}$ = 90°

What is the area of a shaded segment with an area of 12 and an arch angle of 60

Scorpion4ik [409]

Let A = the area of the whole circle
Let S = the area of the shaded portion
The shaded area is a portion of the circle that is determined by the ratio of the shaded sector to the whole circle of 360 degrees, or
S = (60/360) × A = ( 1 / 6 ) × 12 = 2 ;
