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

As delivery truck drove an average of 42 mph it took two hours and 15 minutes to travel between two towns what is the distance between the two towns
Answer:
The distance is 10.5 miles
Step-by-step explanation:
Mathematically; we want to calculate the distance between the two towns in the question
Distance = speed * time
15 minutes to hours is 15/60 = 1/4 hours
So the distance would be;
Distance = 42 mph * 1/4 = 10.5 miles

x=12, y=[tex]6\sqrt{2}[/tex]
This triangle is a special right triangle, a 45-45-90 triangle. In this format, the the hypotenuse will be [tex]x\sqrt{2}[/tex], while the side lengths would be x. With this in mind we can already figure out y is [tex]6\sqrt{2}[/tex]. The hypotenuse would be [tex](6\sqrt{2} )(\sqrt{2} )=12[/tex]
please help!!(GIVING BRAINILEST) Which number line shows the solution of -3x+6>12?
Answer:
The answer is D
Step-by-step explanation:
Answer: C
Step-by-step explanation:
−3x + 6 > 12
Move all terms not containing x to the right side of the inequality.
Subtract 6 from both sides of the inequality.
−3x > 12 − 6
Subtract 6 from 12.
−3x > 6
Divide each term by −3 and simplify.
Divide each term in −3x > 6 by −3. When multiplying or dividing both sides of an i nequality by a negative value, flip the direction of the inequality sign.
(-3x/-3)<(6 /-3)
Cancel the common factor of −3.
Divide 6 by −3.
x < −2
( − ∞ , − 2 )
Evaluate the expression when x = 9.2 and y = 3.4.

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.

The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180, that is
35 - 5 - 8x - 2x = 180 ( simplify left side )
30 - 10x = 180 ( subtract 30 from both sides )
- 10x = 150 ( divide both sides by - 10 )

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
= 4.123 * 0.7660
= 3.16

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.

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]
