132 miles
Step-by-step explanation:
Answer:
B)313 ft
Step-by-step explanation:
Hello,I think I can help you with this
to solve this you need to find all the measures of the rigth triangle formed by Hailey, the boat, and the point on the surface of the sea just above the head of Hailey
Step 1
define
triangle
Hypotenuse=300 feet
opposite side=y
adjacent side=x
angle of depression =30°
Step 2
find the distances

so, the point on the surface of the sea just above hailey is 259.8076 ft from the boat

hailey is at a depth of 150 feet
Step 3
now,her partner is 25 feet directly below her,it is
partner's depth is =hailey is at a depth of 150 feet+25
Y=175
he is at the same distance from de boat ( horizontal),because it is the same point in the sea surface.
X=259.80
Step 4
to find the distance between the partner and the boat we can use
Pythagoras theorem
![adjacentside^{2} +opposite side^{2} =hypotenuse^{2} \\\sqrt[2]{adjacentside^{2} +opposite side^{2}} =Hypotenuse\\Hypotenuse=\sqrt[2]{175^{2} +259.8076^{2}} \\\\Hypotenuse=313.24 ft](https://tex.z-dn.net/?f=adjacentside%5E%7B2%7D%20%2Bopposite%20side%5E%7B2%7D%20%3Dhypotenuse%5E%7B2%7D%20%5C%5C%5Csqrt%5B2%5D%7Badjacentside%5E%7B2%7D%20%2Bopposite%20side%5E%7B2%7D%7D%20%3DHypotenuse%5C%5CHypotenuse%3D%5Csqrt%5B2%5D%7B175%5E%7B2%7D%20%2B259.8076%5E%7B2%7D%7D%20%5C%5C%5C%5CHypotenuse%3D313.24%20ft)
so, Hailey's diving partner is 313 ft away from the boat(B)
Have a great day.
The order from the least to the greatest is
,
,
, and
.
Step-by-step explanation:
Step 1:
We must determine each of the individual values to be able to arrange the given numbers.

means that so 1 and 7 in the decimal keep repeating so,

and

Now that we have all the four values, we can arrange them in ascending order.
Step 2:
There are two negative numbers, the greater a negative number the lesser it is i.e. 
So the least value is
which is followed by
.
The other two are positive numbers. As
so the highest number is
.
So the order from the least to the greatest is
,
,
, and

Answer:
$1155
Step-by-step explanation:
Richard earns $10.50 per hour and he worked for 275 hours.
First find out the total amount he earns.
Total = 275 hours x $10.50 = $2887.50
40% of the earnings go to saving.
Now we find out how much is 40% of the earnings.
Saving = 40% of $2887.50 = 0.4 x 2887.5 = $1155
