The angle between the two given vectors is 16.26°
How to find the angle between two vectors?
Here we have the vectors u = (3, 4) and y = (4, 3).
We know that:
u*y = |u|*|y|*cos(θ)
Then:
u*y = 3*4 + 4*3 = 24
And:
|u| = √(3^2 + 4^2) = √25 = 5 = |y|
Then we have:
24 = 5*5*cos(θ)
24/25 = cos(θ)
To find theta, we apply the inverse cosine function in both sides:
Acos(24/25) = θ = 16.26°

Mr. Clemens painted his barn for 3 and 4/5 hours in the morning. He painted the barn for 5 and 3/4 hours in the afternoon. How many more hours did Mr. Clemens paint the barn in the afternoon than in the morning?
Answer:
1 19/20 hours
Step-by-step explanation:
We solve the above question using Subtraction operation
Hence:
The number rod hours Mr. Clemens painted the barn in the afternoon than in the morning is calculated as:
5 3/4 hours - 3 4/5 hours
5- 3 +( 3/4 - 4/5)
Lowest Common Denominator = 20
2 + (15 - 16/20)
2 + -1/20 hours
= 1 19/20 hours
A deep sea diver is at 45 feet below sea level. A helicopter is at 100 feet above sea level. What is the distance between the helicopter and deep sea diver?
Answer:
D = 55 feet
Step-by-step explanation:
Let below sea level is negative direction and above sea level is positive direction.
A deep sea diver is at 45 feet below sea level = -45 feet
A helicopter is at 100 feet above sea level = +100 feet
We need to find the distance between the helicopter and deep sea diver. It can be calculated by simply adding the above data as follows:
D = -45 +100
= 55 feet
Hence, the distance between the helicopter and deep sea diver is 55 feet.

In a winter storm, the amount of snowfall is directly proportional to the time
it has been snowing. After 4 hours, a total of 7 inches of snow has fallen. Determine how many inches of
snowfall have fallen after 6 hours. Show the work that leads to your answer.
Answer:
10.5 Inches of snow after 6 hours
Step-by-step explanation:
First you would divide
7/4=1.75
Then you would multiply by 6
1.75*6=10.5
10.5 inches of snow would be the total
Hope this helped! :D
The amount of snowfall in 6 hours, if the amount of snowfall is directly proportional to the time, is 10.5 inches.
What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a whole. According to the definition of proportion, two ratios are in proportion when they are equal.
Given:
In a winter storm, the amount of snowfall is directly proportional to the time,
After 4 hours, a total of 7 inches of snow had fallen,
Calculate the amount of snowfall in one hour as shown below,
amount of snowfall in one hour = 7 / 4
Calculate the amount of snowfall that occurs in 6 hours,
Amount of snowfall in 6 hours = 7 / 4 × 6
Amount of snowfall in 6 hours = 10.5 inches

An isosceles triangle has an angle that measures 50° Which other angles could be in that
isosceles triangle? Choose all that apply
Step-by-step explanation:
well I don't know what the answer choices are but here's some information that could help.
all of the angles in a triangle have to add up to 180°
and isosceles triangles have at least two sides that are congruent. This also means that at least two angles have to be congruent
based on this there could be two angles that measure 50° and the last angle would measure 80°
or one angle could measure 50° and the other two angles each measure 65 degrees

The chicken coop at the petting farm is 10 x 14‘. The farm would like to double the current area by adding the same amount, X, to the length and width. What are the dimensions of the new enclosure? Round to the nearest hundredth of a foot
Answer:
x = 4.85 feet
Step-by-step explanation:
Original area of the petting farm = 10 × 14
= 140 square feet
.
New area = double the original area = 140 * 2
= 280 square feet
New area of the petting farm =
Width × length
280 = (10+x) × (14+x)
280 = 140 + 10x + 14x + x²
280 - 140 = x² + 24x
140 = x² + 24x
x² + 24x - 140 = 0
Solve the quadratic equation
x = -b ± √b² - 4ac / 2a
= -24 ± √(24)² - 4*1*-140 / 2*1
= -24 ± √ 576 - (-560) / 2
= -24 ± √ 576 + 560 / 2
= -24 ± √1,136 / 2
= -24 ± 4√71 / 2
= -24/2 ± 4√71/2
= -12 ± 2√71
x = 4.8523 or x = -28.8583
x can not be a negative value
Therefore,
x = 4.85 feet to the nearest hundredth

You know the length and the width of a scale model. What additional information do you need to know to find the scale of the model? The options are... A. The width or height of the actual item B. The length or width of the actual item C. The height or width of the actual item D. The depth or height of the actual item and how would I explain my reasoning depending on the answer?
Answer:
B; The length or width of the actual item
Step-by-step explanation:
In cases like this, to find the scale factor, we will need to make a comparison between the length or width of the scale model and the length or width of the actual item
By having a further information about the length or width of the actual item, then we can actually make a comparison by dividing the length or width of both cases by each other
This means that we compare the length of the scale model and the length of the actual item
Then the width of the scale model and the width of the actual item
