Answer:
D. 112°
General Formulas and Concepts:
A line is always 180°.
Order of Operations: BPEMDAS
Step-by-step explanation:
Step 1: Set up equation
m∠ABD + m∠DBC = m∠ABC
(3x + 10) + (2x) = 180°
Step 2: Solve for x
Combine like terms: 5x + 10 = 180Subtract 10 on both sides: 5x = 170Divide 5 on both sides: x = 34Step 3: Find m∠ABD
m∠ABD = 3x + 10
Substitute: m∠ABD = 3(34) + 10Multiply: m∠ABD = 102 + 10Add: m∠ABD = 112°five decreased by twice a number

Is(1, 6)a solution to the inequality y < 4x + 2?
Answer:
yes, (1,6) is a solution to the inequality y<4x+2.
Step-by-step explanation:
Looking at the equation we can see that the slope is 4 and the y intercept is 2.
Now we will use the slope that is comprised of the rise over the run which is [tex]\frac{rise}{run}[/tex]
The slope is 4 this means that [tex]\frac{rise}{run}[/tex] = [tex]\frac{4}{1}[/tex] and this shows us that the rise is 4 and the run is 1, so starting at (0,2) you go up 4 and over 1 so our next coordinate would be (1,6)
so the answer is yes, (1,6) is a solution to the inequality y<4x+2.

a water balloon was thrown from the window. The height of the water balloon over time can be modeled by the function y=-16square2+160x+50
The maximum height of the water balloon : 450 m
Further explanationQuadratic function is a function that has the term x²
The quadratic function forms a parabolic curve
The general formula is
f (x) = ax² + bx + c
where a, b, and c are real numbers and a ≠ 0.
The parabolic curve can be opened up or down determined from the value of a. If a is positive, the parabolic curve opens up and has a minimum value. If a is negative, the parabolic curve opens down and has a maximum value
So the maximum is if a <0 and the minimum if a> 0.
The formula for finding the coordinates of the maximum and minimum points of the quadratic function is the same.
The maximum / minimum point of the quadratic function is
[tex]\rm -\dfrac{b}{2a},-\dfrac{D}{4a}[/tex]
Where
D = b²-4ac
The function h (t) = -16x²+160x+50
so the value of a <0, then it has a maximum value
Because we are looking for maximum height, then we find the value of the y coordinate, with the formula
[tex]\rm -\dfrac{D}{4a}[/tex]
Questions we might add :
What was the maximum height of the water balloon after it was thrown?
We can also use the first derivative of the above function to find the maximum value
[tex]\tt h'=0=-32x+160\\\\-32x=-160\\\\x=5[/tex]
input to function :
[tex]\tt h=-16x^2+160x+50\\\\h=-16(5^2)+160(5)+50\\\\h=-400+800+50=\boxed{\bold{450~m}}[/tex]
find a ratio that equivalent to 3 to 8
Answer:
6 to 8
Step-by-step explanation:
3 and 8 multiplied by two will give an equivalent ratio
The ratio shows how many times one value is contained in another value.
The ratios that are equivalent to 3 to 8 are:
9/24, 12/32, and 15/40.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
3:8
= 3/8
We can have many ratios that is equivalent to 3:8
9/24 = (3 x 3) / (3 x 8) = 3/8
12/32 = (4 x 3) / (4 x 8) = 3/8
15/40 = (5 x 3) / (5 x 8) = 3/8
Thus,
The ratios that are equivalent to 3 to 8 are:
9/24, 12/32, and 15/40.

Correct Option: [tex]\angle XVW[/tex] and [tex]\angle YVX[/tex] are the same size
Step-by-step explanation:
Two angles are adjacent when they have a common side, a common vertex, and don't overlap.
The image shows the following angles are adjacent:
YVZ and YVX
YVZ and YVW
YVX and XVW
Furthermore, two angles are said to be linear if they are adjacent angles formed by two intersecting lines.
The first, fourth, and fifth options are true as shown above, which discards as true the second option.
The only probable false option is that XVW and YVX are the same size. They certainly could be, but we have to evidence of that, thus this option is considered false.

I need help with #6 & #7 !!
Answer:
6 is b, 7 is c
Step-by-step explanation:
Answer:
#6 wants you to find out what answer from the 4 expressions gives you the least or smallest number. For #7, you need to follow PEMDAS in order to get the right answer.
Step-by-step explanation:
#6, the answers you get are 8, -9, -3, and 9. You need to choose the smallest number. Negative numbers are smaller than positive numbers, so you can immediately eliminate 8 and 9. You have to be careful when comparing negative numbers because the larger negative number is actually smaller than the smaller negative number since it is further away from the zero. So, negative -9 would be smaller than -3 in this case.
#7, I would divide the -720/12 first. This results in -60. Then, divide the -60 by -10. This gives you an answer of positive 6.

2.Jo A certain shade of pink is created by adding 3 cups of red paint to 7 cups of white paint. How many cups of red paint should be added to 1 cup of white paint? Explain how you know. 3/7 I know this because I did 7 divided by 3 which Was 2 ⅓ so then I did 1 times 2 ⅓ which is 2 . ⅓. What is the constant of proportionality? Explain how you know. 3/7 is the constant of proportionality.
Answer:
x = 3/7
Step-by-step explanation:
Red paint : White paint = 3 cups : 7 cups
How many cups of red paint should be added to 1 cup of white paint
Red paint : White paint = x cups : 1 cup
Equate the ratios
3 cups : 7 cups = x cups : 1 cup
3 / 7 = x / 1
Cross product
3 * 1 = 7 * x
3 = 7x
Divide both sides by 7
x = 3 / 7
Number of cups of cups of red paint that should be added to 1 cup of white paint is 3/7
I did this by representing the unknown number of cups of red paint with x and equating the two ratios
A class ordered six 8-slice pizzas. Each student ate 1 1/2 slices and no pizza was left over. How many students were there?
Answer:
There are 32 students.
Step-by-step explanation:
If there are six 8-slice pizzas, that means that there is 48 slices total. If each student ate 1 1/2 slices, you can divide 48 and 1.5, and you will get 32. That is the number of students in the class. Hope this helps!
The Library of Congress in Washington D.C. Is considered the largest library in the world. They often receive boxes of books to be added to their collection. Since books can be quite heavy, they aren't shipped in big boxes. If, on average, each box contains about 8 books, how many books are received by the library in 6 boxes, 10 boxes, or n boxes? Use the space below to tell me how many books are received in: 6 boxes = 10 boxes = n boxes = (Hint: Write an equation!)
Answer: The number of books in 6 boxes = 48
The number of books in 10 boxes = 80
The number of books in n boxes = 8n
Step-by-step explanation:
Given : Each box has contains about 8 books.
Total books : (Number of books in each box) x (Numbers of boxes).
Then, the number of books in 6 boxes = 8 x 6 = 48
Similarly,
The number of books in 10 boxes = 8 x 10 = 80
The number of books in n boxes = 8n
Hence, The number of books in 6 boxes = 48
The number of books in 10 boxes = 80
The number of books in n boxes = 8n
