The missing number in the arithmetic sequence 60, 51, ___, 33 is:
Answer:
42
Step-by-step explanation:
In this question, we have the find the rate of change in the sequence.
To find this, we need to find how much the sequence is changing by.
We know from 60 to 51 is -9, so we know that our sequence is changing by -9.
To find our unknown number, we would subtract 9 from 51.
51 - 9 = 42
Our missing number in the sequence is 42.
We can check our answer by subtracting 9 from 42. This gives us our next number, which is 33.
42 would be your answer.

Step-by-step explanation:
Samantha makes a conjecture that the product of two odd integers is always an odd integer. Which choice is the best proof of her conjecture? CLEAR CHECK Look at these different examples: 7 × 3 = 21, 5 × 9 = 45, 11 × 3 = 33. So the product of two odd numbers must be odd. Every time you multiply two odd numbers, the product is an odd number. Let (2a + 1) be an odd number. Let (2b + 1) be another odd number. The product 2(2ab + a + b) + 1 is a multiple of 2 plus 1, which is an odd number. Let a and b both represent odd numbers, and let a × b be an odd number. Therefore, a × b = b × a, which shows that the product of two odd numbers is odd.
Answer:
Let (2a + 1) be an odd number. Let (2b + 1) be another odd number. The product 2(2ab + a + b) + 1 is a multiple of 2 plus 1, which is an odd number.

A hemispherical tank is filled with water and has a diameter of 14 feet. If water
weighs 62.4 pounds per cubic foot, what is the total weight of the water in a full tank,
to the nearest pound?
Answer:
[tex]44,826.72\ \text{pounds}[/tex]
Step-by-step explanation:
Given that,
The diameter of a hemispherical tank= 14 feet
Radius, r = 7 feet
water
Water weighs 62.4 pounds per cubic foot.
We need to find the total weight of the water in a full tank to the nearest pound.
The volume of the hemisphere is given by :
[tex]V=\dfrac{2}{3}\pi r^3\\\\V=\dfrac{2}{3}\pi \times (7)^3\\\\V=718.377\ \text{feet}^3[/tex]
If water weighs 62.4 pounds per cubic foot, it means
[tex]V=718.377\times 62.4\\\\V=44,826.72\ \text{pounds}[/tex]
So, the total weight of the water is [tex]44,826.72\ \text{pounds}[/tex].

If point A(-8, 5) is reflected over the line y=2 and then translated according to the rule (x,y) -> (x-1, y-4), what quadrant will point A be in?
9514 1404 393
Answer:
3rd quadrant
Step-by-step explanation:
The second-quadrant point will lie in the 3rd quadrant after reflection over the line. Its coordinates there will be ...
A'(-8, 2·2 -5) = A'(-8, -1)
Then, translation down and to the left will move it further into the 3rd quadrant, to ...
A''(-8-1, -1-4) = A''(-9, -5) . . . . a 3rd-quadrant point

someone please help me this is really confusing
Answer:
Area of trapezoid is: [tex]\mathbf{11x^3y^2}[/tex]
Area of triangle is: [tex]\mathbf{6a^3b^2}[/tex]
Perimeter of triangle is: [tex]\mathbf{3ab+14a^2b}[/tex]
Step-by-step explanation:
Image 1:
We need to Find area of trapezoid.
The formula used is: [tex]Area=\frac{1}{2}h(b_1+b_2)[/tex]
where h is height and b₁ and b₂ are parallel sides.
Looking at the figure we get:
h = 2xy
b₁ = 4x²y
b₂ = 7x²y
Putting values and finding area:
[tex]Area=\frac{1}{2}h(b_1+b_2)\\Area=\frac{1}{2}\times 2xy(7x^2y+4x^2y)\\Area=\frac{1}{2}\times 2xy(11x^2y)\\Area=\frac{1}{2}\times 22x^3y^2\\Area=11x^3y^2[/tex]
So, Area of trapezoid is: [tex]\mathbf{11x^3y^2}[/tex]
Image 2:
We need to find area and perimeter of triangle.
First we will find area of triangle.
The formula used is: [tex]Area=\frac{1}{2}\times b \times h[/tex]
where b is base and h is height
Looking at the figure,
b = 3ab
h = 4a²b
Finding area:
[tex]Area=\frac{1}{2}\times b \times h\\Area=\frac{1}{2}\times 3ab \times 4a^2b\\Area=\frac{1}{2}\times 12a^3b^2\\Area=6a^3b^2[/tex]
So, Area of triangle is: [tex]\mathbf{6a^3b^2}[/tex]
Now, finding Perimeter of triangle
The formula used is: [tex]Perimeter = Sum\:of\:lengths\:of\:all\:sides\:of\:triangle[/tex]
Looking at figure:
Length of side 1 = 3ab
Length of side 2 = 4a²b
Length of side 3 = 10a²b
Finding Perimeter
[tex]Perimeter = Sum\:of\:lengths\:of\:all\:sides\:of\:triangle\\Perimeter = 3ab+10a^2b+4a^2b\\Perimeter=3ab+14a^2b[/tex]
So, Perimeter of triangle is: [tex]\mathbf{3ab+14a^2b}[/tex]

Q: A is 8km due north of phone mast B. C is 9.5km due west of phone mast B. Calculate the distance AC
Answer:
AC = 12.4 km (nearest tenth)
Step-by-step explanation:
AC can be calculated by using Pythagorean Theorem.
Thus:
AC² = AB² + BC²
Plug in the values
AC² = 8² + 9.5²
AC + √{154.25)
AC = 12.4 km (nearest tenth)
The ration of child to teen to adult tickets sold at a water park on Saturday was 4:1:2. A total of 294 tickets were sold. How many child tickets were sold?
Answer: 168 child tickets were sold.
Step-by-step explanation:
Given: The ratio of child to teen to adult tickets sold at a water park on Saturday was 4:1:2.
Let the number of child tickets = 4x , teen tickets = x , adult tickets = 2x
Total tickets = x+4x+2x = 7x =294
[tex]\Rightarrow\ x=\dfrac{294}{7}\\\\\Rightarrow\ x=42[/tex]
Number of child tickets = 4(42) = 168
Hence, 168 child tickets were sold.

On a coordinate plane, a rectangle has points (0, 0), (0, 1), (4, 1), (4, 0).
On a coordinate plane, a rectangle has points (0, 0), (0, 2), (8, 2), (8, 0).
I HAVE 30 MINUTES LEFT ON A TIMED ASSIGNMENT!!!
9514 1404 393
Answer:
(a) On a coordinate plane, a rectangle has points (0, 0), (0, 1), (2, 0), (2, 1)
Step-by-step explanation:
Every point coordinate of the dilated figure will be smaller by the same factor.
Looking at the original (0, 3) coordinate, we find that possible answer choices include ...
A (0, 1) has a scale factor of 1/3
B (0, 4) has a scale factor greater than 1
C (0, 1) has a scale factor of 1/3
D (0, 2) has a scale factor of 2/3
__
Looking at the rest of the points in the answer selections, we find that the scale factors in choices C and D are not consistent from one point to another (or even within the same point). Those choices must be rejected.
In selection A, the image points are listed out of order, tending to confuse the issue. However, A is the correct choice.

Help me please 9w+4= 2w+32
Answer:
w=4
Step-by-step explanation:
9w+4=2w+32
-2w -2w
7w+4=32
-4 -4
7w=28
w=4
Answer:
w = 4
Step-by-step explanation:
How to solve...
You have your equation 9w + 4 = 2w + 32, now you take 4 and subtract on both sides, so you will subtract it to 4 and 32. You get 28 as your answer. Now leave that alone, next you will take 2w and subtract it on both sides, when you subtract 2w to 9w you will get 7w. Now just do 28 divided by 7, which is 4. So w = 4. Hope this helps!
9w + 4 = 2w + 32
- 4 = - 4
--------------------------
9w = 2w + 28
-2w = -2w + 28
---------------------------
7w = 28
7w = 7w
---------------------------
w = 4
