what is 62 1/2% as a decimal?
Answer:
62.50 or 0.625
Step-by-step explanation:
The decimal form of [tex]62\frac{1}{2}[/tex] percent is 0.625.
The given percentage is [tex]62\frac{1}{2}[/tex] %
This fraction is in a mixed fraction.
Convert it into an improper fraction
So,
[tex]62\frac{1}{2}[/tex] % = (62x2 + 1)/2
= (124+1)/2
= 125/2 %
Now divide 125 by 2 to get the decimal form
2) 125 ( 62.5

can a pentagon have interior angles that measure 120°, 105°, 65°, and 95°? explain.
Answer:
No
Step-by-step explanation:
because firstly, pentagon is five sided figure and secondly, the sum of interior angled of a pentagon is 540°
No, the given angles can not be the measure of the pentagon angles.
What is the pentagon?A pentagon is a polygon having five sides connected to each other to form a closed figure. The sum of the angles of the pentagon is equal to 540 degrees.
Given angles are 120°, 105°, 65°, and 95°. Here as we know that the pentagon is a polygon having five sides. The number of angles formed by all the sides of the pentagon is also five.
Here we have only four angles that are 120°, 105°, 65°, and 95°. But to form a pentagon there must be five angles and the sum of the angles should be 540 degrees.
Therefore, the given angles can not be the measure of the pentagon angles.

Parellel lines it says 75 degrees and on another line it says 11x-2 what's the answer?
Answer:
x = 7
Step-by-step explanation:
Parallel lines so their the same
11x - 2 = 75
add 2 to both sides
11x = 77
divide both signs with 11
x = 7
Answer:
The answer to the equation below is also 75 degrees. X equals 7
Step-by-step explanation:
Assuming that the lines are parallel, we can confirm that the two angles are corresponding because they are cut by a traversal (corresponding means that they occupy the same relative position). Knowing that the are corresponding use the equation 11x-2= 75 to find x. You are welcome and I hope you get the best grade possible :). Have a nice day!

Suppose a triangle with angles measuring 30°, 35°, and 115º is translated 1 unit left and 1 unit up on a coordinate grid.
Which would be the measure of an angle of the resulting triangle?
25°
35°
55°
65°
Answer:
35
Step-by-step explanation:
The triangle just moved. To translate an object doesn't change anything, it just changes the positioning.
Ex. Moving a box 1 foot forward and 1 foot to the left. I did nothing to the box, therefore the answer is 35 degrees since that is the only question there

Using the inverse of the sine function, it is found that the value of x is:
[tex]x = -\frac{\pi}{6}[/tex]
What is the inverse sine function?It is the function described by:
[tex]y = \arcsin{x}[/tex]
And means that sine of y is equals to x, that is:
[tex]x = \sin{y}[/tex]
In this problem, the function is:
[tex]x = \arcsin{-\frac{1}{2}}[/tex]
Which means that we have to solve for x, considering that the sine of x is of -1/2. Hence:
[tex]\sin{x} = -\frac{1}{2}[/tex]
[tex]x = -\frac{\pi}{6}[/tex]
Hence, the value of x is given by:
[tex]x = -\frac{\pi}{6}[/tex]

Consider vectors u = ⟨2, 1⟩ and v = ⟨4, –1⟩ with the angle between them equal to 40°. What are the scalar projections uv and vu?
a) uv = 1.33 and vu = 1.33
b) uv = 1.33 and vu = 3.16
c) uv = 1.71 and vu = 1.33
d) uv = 1.71 and vu = 3.16
Answer:
D. uv = 1.71 and vu = 3.16
Step-by-step explanation:
The scalar projections are uv = 1.71 and vu = 3.16
The correct option is (D)
What is meant by scalar projection?The definition of scalar projection is the length of the vector projection.
Given: u = ⟨2, 1⟩, = ⟨4, –1⟩, and θ = 40°
Proj u_v = |u| cosθ
= 2.25 * cos 40
= 2.25 * 0.7660
=1.72
and, Proj v_u = |v| cosθ
= 4.123 * cos 40

Each deli sandwhiches made uses 8/8 pound of roast beef.Marisa started with 5 pounds of roast beef and now has 2 3/4 pounds left. How many del sandwhiches did she make
Answer:
Marisa has made 6 sandwiches.
Step-by-step explanation:
The pounds of roast beef required to make each sandwiches is [tex]\frac{3}{8}[/tex], and not [tex]\frac{8}{8}[/tex] as erroneously typed in the question.
Given that each deli sandwiches made, uses [tex]\frac{3}{8}[/tex] pounds of roast beef.
Marisa started with 5 pounds, and had 2[tex]\frac{3}{4}[/tex] pounds left.
Thus,
pounds of roast beef used = 5 - 2[tex]\frac{3}{4}[/tex]
= 5 - [tex]\frac{11}{4}[/tex]
= [tex]\frac{20 - 11}{4}[/tex]
= [tex]\frac{9}{4}[/tex]
= 2[tex]\frac{1}{4}[/tex]
Marisa had used 2[tex]\frac{1}{4}[/tex] pounds of roast beef. So that;
the number of del sandwiches made = 2[tex]\frac{1}{4}[/tex] ÷ [tex]\frac{3}{8}[/tex]
= [tex]\frac{9}{4}[/tex] ÷ [tex]\frac{3}{8}[/tex]
= 6
Therefore, the number of sandwiches made by Marisa is 6.
Evaluate the expression when x = 9.2 and y = 3.4.
