DMS to Decimal Degree Conversion:To translate decimal degrees into DMS, take the following actions:
The whole number portion of the decimal should be used for the degrees.Divide the last decimal by 60 to get the minutes. Employ a whole number.minutes as a portion of the response.Add 60 to the new decimal to account for the seconds.According to the given information:Converting the following angles from decimal degrees to degrees, minutes, and seconds.
A) 45.5013
The whole number is degrees. So 45.5013 gives you 45degrees.

If angle m∠SOP=(7y-12)° and m∠SOR=(5y+12)°, then the value of y=15 and m∠SOP is equal to 93°.
Given that m∠SOP=(7y-12)° and m∠SOR=(5y+12)°.
We are required to find the value of y and the angle m∠SOP.
We know that sum of all the angles which lie on the straight line is equal to 180°.
And here m∠SOP and m∠SOR both lie on the straight line PR. So,
m∠SOP+m∠SOR=180
7y-12+5y+12=180
12y=180
y=180/12
y=15
We have to use y=15 in m∠SOP=(7y-12)°.
m∠SOP=7*15-12
=105-12

8. You are skiing down a 1,350 meter ski slope at 60 meters per second. Let t
represent your skiing time in seconds and d(t) represent the distance from the
bottom of the ski slope.
The time taken to reach the bottom when the person skies down will be 22.5 seconds.
How to calculate the value?It should be noted that the person is skiing down a 1,350 meter ski slope at 60 meters per second.
There, t represent your skiing time in seconds.
The appropriate expression to illustrate the scenario will be:
1350 - 60t = 0

Given,
The radius of the circle = 3x
The area of the circle = [tex]\pi r^{2}[/tex]
Where r is the radius of the circle
Substitute the values in the equation
Area of the circle = [tex]\pi (3x)^{2}[/tex]
=[tex]9x^{2} \pi[/tex]
We know when a circle is inscribed in a square the diameter of the circle is equal to the side of the square
Diameter of the circle = 2× radius

The area of the square = [tex]a^{2}[/tex]
Where a is the side of the square
Area of the square = [tex](6x)^{2}[/tex]

Examine the triangles. Two similar triangles. The first triangle has a side length of 6 inches, which corresponds to the second triangle's side of 18 inches. The first triangle has a side length of 11 inches that corresponds to the missing side on the second triangle. If the triangles are similar, what is the length of the missing side? Note: The triangles may not be drawn to scale.
The length of the missing side of the triangle is 33 inches.
What are similar triangles?Similar triangles are those triangles whose corresponding sides are in the same ratio. And the corresponding angles measure the same. It is denoted by ‘~’ symbol.
Let the length of the unknown sides of the second triangle be represented by x.
Given that the two triangles are similar triangles, therefore, the length of the corresponding sides will be in the same ratio. Thus, we can write the ratio of the sides of the triangle as,
6 inches / 18 inches = 11 inches / x
x = (11 inches × 18 inches) / 6 inches
x = 33 inches

Answer:
62º
Step-by-step explanation:
So this is supplementary angles. Supplementary angles are two or more angles that add up to 180º. This is also vertical angles. Vertical angles are angles across from one another that are congruent(such as the 180º angle and the one up and to the right of it). So if vertical angles are congruent that means that the angle to the right of x is also 118º. And since it is a supplementary angle this is now simple subtraction.
180-118=62.

A, B & C form the vertices of a triangle, where ∠CAB = 90°.
AB = 10.2 m and AC = 5.6 m.
Evaluate ∠CBA, giving your answer rounded to 3 SF.
The unknown angle of the right triangle is as follows:
∠CBA = 28.8°
How to find the angle of a right triangle?The triangle is a right triangle because one of its angle is equals to 90 degrees.
The angle ∠CBA, can be found using trigonometric rations,
hence,
tan ∅ = opposite / adjacent
where
∅ = ∠CBA
Therefore,
tan ∠CBA = opposite / adjacent
opposite side = 5.6 m
adjacent side = 10.2 m
Hence,
tan ∠CBA = 5.6 / 10.2
tan ∠CBA = 0.54901960784
tan ∠CBA = 0.54901960784
∠CBA = tan⁻¹ 0.54901960784
∠CBA = 28.7676493388

How to write the graphed inequality?
We can see that we have an absolute value equation, and the region above the graph is shaded, so we have:
y ≥ absolute value equation
We can see that the slope of the absolute value equation is 1, and the vertex is (5, 1), then the equation is:

Answer:
y = -2/7x + 2
Step-by-step explanation:
y=mx + b is the slope intercept form of a line. The b is the y-intercept. We are given that. The point (0,2) tells us that the line crosses the y intercept at 2.
Now we have to find the slope. The slope is the change in y over the change in y. Given the points (7,0) and (0,2) The y's are 2 and 0 and the x's are 0 and 7. Subtract the y's and subtract the x's.
[tex]\frac{2 - 0}{0 - 7}[/tex] = [tex]\frac{-2}{7}[/tex]

Alita received 24 dollars and 25 cents ($24.25) as change at the grocery store.
For given question,
Alita received twenty-two dollars, seven quarters, and five dimes as change at the grocery store.
The value of coins is all counted in cents.
1 Penny = 1 cent
1 Nickel = 5 cents
1 Dime = 10 cents
1 Quarter = 25 cents
And 1 Dollar = 100 cents
Alita received seven quarters, and five dimes coins as change at the grocery store.
seven quarters = (7 × 25) cents
= 175 cents
five dimes = (5 × 10) cents
= 50 cents
The total coins are:
seven quarters, and five dimes
= 175 + 50 cents
= 225 cents
Now we add all change together.
twenty-two dollars, seven quarters, and five dimes
= 22 dollars + 225 cents
= 22 dollars + 2.25 dollars
= 24.25 dollars

The sides of the triangle are as follows:
a = 43 meters
b = 172 meters
c = 341 meters
Given, we have the perimeter of the triangle as 556 meters.
The sides of the triangle are:
a = x meters
b = 4x meters
c = (8x - 3) meters.
we know that perimeter of the triangle = a + b + c
therefore, a + b+ c = Perimeter
x + 4x + (8x - 3) = 556
x + 4x + 8x - 3 = 556
13x - 3 = 556
13x = 556 + 3
13x = 559
x = 559/13
x = 43
hence we get the value of x as 43.
substitute x value in the sides of the triangle to get the orignal values of the sides.
a = x = 43 meters.
b = 2x = 4 × 43 = 172 meters.
c = 8x - 3 = 8(43) - 3 = 341 meters.
Hence the sides of the triangle are 43 meters , 172 meters and 341 meters.
