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]
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

Adele took a total of 12 quizzes over the course of 2 weeks. After attending 5 weeks of school this quarter, how many quizzes will Adele have taken in total? Assume the relationship is directly proportional.
?quizzes
Answer:
30 quizzes
Step-by-step explanation:
12 quizzes in 2 weeks means that there were 6 per week and 6 (quizzes per week) times 5 (number of weeks) would be 30.
Hope this helped!!
Answer:
30, or 42
Step-by-step explanation:
If they took 12 quizzes over the course of 2 weeks, then we can assume that they take 6 quizzes each week (12/2 = 6).
Over the course of 5 weeks, they'll have taken 30 quizzes if the above is true. However, the 'or' is there because I don't know if they're including the past 12 or not. If they are including the 12 quizzes taken over 2 weeks, then the answer is 42. If they are only referring to the 5 weeks of school, then the answer is 30.

Find the volume of the solid formed by rotating the region bounded by the given curves about the indicated axis. y = x3/4, x = 0, y = 1 (in the first quadrant); about the y-axis
The volume of the solid formed by rotating the region about the y-axis is 6π/7 cubic units.
To find the volume of the solid formed by rotating the region bounded by the curves y = x³/4, x = 0, y = 1 in the first quadrant about the y-axis, we can use the method of cylindrical shells.
The formula for the volume using cylindrical shells is:
[tex]\mathrm V = \int\limits^a_b {2\pi \mathrm x \times \mathrm f(x)} \, dx[/tex]
Where:
a and b are the limits of integration (in this case, a = 0 and b = 1 since we are rotating in the first quadrant).
f(x) is the height of the shell at the given x-value.
2πx is the circumference of the shell at the given x-value.
In this case, we need to express y = x³/4 in terms of x to find the function f(x).
Given: y = x³/4
To find the function in terms of x, solve for x:
[tex]x = (4y)^{(1/3)[/tex]
Now, the function f(x) becomes:
[tex]\mathrm f(x) = (4x)^{(1/3)[/tex]
Now, let's calculate the volume using the cylindrical shell method:
[tex]\mathrm V = \int\limits^1_0 {2\pi \mathrm x \times \mathrm 4x^{1/3}} \, dx[/tex]
[tex]\mathrm V = 2\pi \int\limits^1_0 { x^{4/3}} \, dx[/tex]
To integrate, add 1 to the exponent and divide by the new exponent:
[tex]\mathrm V = 2\pi \times (3/7) \times x^{(7/3)} |^0_1[/tex]
Now, evaluate the expression at the limits of integration:
[tex]\mathrm V = 2\pi \times (3/7) \times (1)^{(7/3)} - 2\pi \times (3/7) \times (0)^{(7/3)[/tex]
[tex]\mathrm V = 2\pi \times (3/7) - 0[/tex]
[tex]\mathrm V = 6\pi/7[/tex]
So, the volume of the solid formed by rotating the region about the y-axis is 6π/7 cubic units.

Step-by-step explanation:
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 )
x = - 15
In an aquarium, there are 3 red, 6 yellow, 4 white and 2 black fish. Find the ratio of the: a) Number of yellow fish to the number of white fish. b) Number of black fish to the total number of fish. c) Number of red fish to the number of black fish.
Answer:
a. 3 : 2
b. 2 : 15
c. 3 : 2
Step-by-step explanation:
Red fish = 3
Yellow fish = 6
White fish = 4
Black fish = 2
Total number of fishes = 15
a) Ratio of the Number of yellow fish to the number of white fish.
Yellow fish : White fish
6 : 4
= 6 /4
= 3/2
= 3 : 2
Ratio of the Number of yellow fish to the number of white fish = 3 : 2
b) Ratio of the Number of black fish to the total number of fish
Black fish : Total fish
2 : 15
= 2 / 15
= 2 : 15
Ratio of the Number of black fish to the total number of fish = 2 : 15
c) Ratio of the Number of red fish to the number of black fish
Red fish : black fish
= 3 : 2
= 3/2
= 3 : 2
Ratio of the Number of red fish to the number of black fish = 3 : 2
Ty has 230 pages of text to read in the next three days. If he averages 25 pages every 1 1/4 hours, how many hours will he be spending reading?
Answer:
11.5 hrs
Step-by-step explanation:
Divide 230 by 25. Then multiply your quotient by 1.25 which is 1 1/4 to get the number of hours. 230 divided by 25 is 9.2. 9.2 times 1.25 is 11.5

Ok so I’m getting braces in a week and I’m pretty scared about it. But however, does it hurt when they put them in?
Answer:
Ok so I've had braces and it doesn't really hurt getting put in but it does hurt when they tighten them but you have nothing to worry about :)
Step-by-step explanation:
Answer:
They don't hurt when they put them in however you will feel mild soreness and discomfort as your mouth adjusts to them as with anything, for example, fillings, they feel gritty and uncomfortable at first but your mouth adjusts to it.
" There will be mild soreness or discomfort after the orthodontic wire is engaged into the newly placed brackets, which may last for a few days to a week."
I know its can be scary at first but its for the health of your teeth and not everyone gets that privilege, just make sure to take care of them properly.

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

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.
