Astronomers sometimes use angle measures divided into degrees, minutes, and seconds. One degree is equal to 60 minutes, and one minute is equal to 60 seconds. Suppose that ∠J and ∠K are complementary and that the measure of ∠J is 45 degrees, 30 minutes, 14 seconds. What is the measure of ∠K?
The measure of ∠K is ______ degrees, ______minutes, and _____ seconds.
Answer:
Here's what you need to know to answer this question:
If two angles are "complementary"
then they add up to 90 degrees.
So now you know that
(Angle-J) + (Angle-K) = 90 degrees .
Subtract (Angle-J)
from each side: Angle-K = (90 degrees) - (Angle-J)
Angle-K = (90 degrees) minus (48 degrees 26 minutes 8 seconds)
As soon as you do that subtraction, you have the answer.
The thing that makes it tough is subtracting some minutes
and some seconds from 90 degrees.
How you do that is: An unusual kind of regrouping ('borrowing').
Usually, when you regroup, you take '1' from a place and use it
to make '10' in the smaller place.
This time, when you take '1' from a place, it gives you '60'
in the smaller place.
-- Take 1 degree away from the 90 degrees.
Use it to make minutes.
Then you have 89 degrees 60 minutes .
-- Take 1 minute away from the 60 minutes.
Use it to make seconds.
then you have 89 degrees 59 minutes 60 seconds .
Now the subtraction is a lot easier.
89 degrees 59 minutes 60 seconds
minus 48 degrees 26 minutes 8 seconds .
That's easy to do, and the difference is the measure of Angle-K.

Answer:

Step-by-step explanation:
1. Approach
This problem asks one to find the surface area of the given figure. This can be done by splitting the given figure into two similar figures. Then calculate the surface area of each of the similar figures. After doing so, subtract the covered surface areas, the contact point between the two simple figures is not a part of the surface area since it is covered by the other part of the figure. Remember to take away twice the area of this contact point, since it is present on both figures.
2.Find the surface area of the first figure
The surface area of a figure is the two-dimensional space around the figure. In essence, if one were to wrap the figure in paper, the surface area is the amount of paper one would need. Find the 2-dimensional area of each side, this can be done by multiplying all combinations of two dimensions together, adding the results, and then multiplying that value by (2).
(5) * (10) = (50)
(5) * (7) = (35)
(7) * (10) = (70)
Now add thee value together,
(50) + (35) + (70)
= (155)
Double the result,
(155) * (2) = (310)
3. Find the surface area of the other figure
Now repeat the process that was used to find the surface area of the other figure for this figure.
(8) * (4) = (32)
(4) * (3) = (12)
(8) * (3) = (24)
Add the results,
(32) + (12) + (24) = (68)
Double the value,
(68) * (2) = (136)
3. Now subtract the repeated side
Now that one has the value of both simple figures, add up the value and then subtract twice the value of the repeated side.
(310) + (136) = (446)
(446) - ((2)*(4)*(3))
= (446) - (24)
= (422)

The width of a rectangle is 4n - 1.5 feet and the length is 1.5n + 4 feet. Find the perimeter of the rectangle. The perimeter of the rectangle is feet.
(Simplify your answer. Use integers or decinals for any numbers in the expression.)
Answer:
11n + 5
Step-by-step explanation:
First, what is the perimeter of a rectangle referring to? It's referring to the outside surrounding the rectangle. You just need to know that the formula for a rectangular perimeter is:
2(L+W) (W = width, L = length)
We are given width: 4n - 1.5We are given length: 1.5n + 4Now substitute those values for the formula.
2 (4n-1.5 + 1.5n + 4)2 (5.5n + 2.5)11n + 5dexter deposited $6,300 into a savings account that earns 2.60% simple interest per year. how much will he earn in 4 years?
Answer:
= $655.20
Step-by-step explanation:
Simple Interest =( Principal * rate * time)/100
=( $ 6300 * 2.60% * 4years)/100, workout in the brackets first then divide by 100.
= 65520/100
= $655.20
Dexter will earn $655.2.
What is the simple interest?Simple interest is the borrowing amount added only to the principal amount.
Formula to calculate the simple interest is;
S.I. = P x T x R / 100 ,
Where S.I. is simple interest , P is principal amount, T is time period and R is interest rate in a year.
Dexter deposited $6,300 into a savings account that earns 2.60% simple interest per year.
P = $6300
R = 2.60% and T = 4 years
Then by the formula;
6300 x 2.6 x 4 /100
= $655.2
Therefore, Dexter will earn $655.2.

A bat is sitting in a tree. He leaves the tree and flies up to a speed of 4 meters per second in 8 seconds. How far does he travel?
Answer:
32 meters
Step-by-step explanation:
4*8=32 and you have to do this because he flies 4 meters per second and in 8 seconds
With the given speed and time a bat travelled 32 meters.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
Given that, A bat is sitting in a tree. He leaves the tree and flies up to a speed of 4 meters per second in 8 seconds.
We know that, speed = Distance/Time
Now, 4 = Distance/8
Distance = 32 meters
Therefore, a bat travelled 32 meters.
