in a list of all 3 digit numbers whose digits add up to 9, what is the median
Answer:
Waddup bro. For your answer, think of it this way. What 3 digits will make up 9? 1 x 9 is 9. So that would work. find it out by trying out different combination that would make up 9. I'm not gonna write all of 'em but 3 digits would add up to 9. There are no other groups of numbers adding up to 9. 4. Add up the remaining digits, 5 + 5 + 0 + 3 = 13. 5.13 is more than 9, so 1 + 3 = 4. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers. So add all up the singe digits and divide it by how much there is.

The graph shows the amount of water that remains in a barrel after it begins to leak. The variable x represents the number of days that have passed since the barrel was filled, and y represents the number of gallons of water that remain in the barrel. A graph titled Water Supply with number of days on the x-axis and gallons of water left on the y-axis. A line goes through points (6, 33) and (15, 15). What does the y-intercept represent?
Answer:
its c i guess i thought it was B because it says the amount of water that remains in the water barrel remains means what is left and initially means at first so i guess its C
Step-by-step explanation:
please rate and give me a thanks if you wanna get more answers
Here, we are required to determine what the y-intercept represents.
The equation of a line is given by;
y = mx + c.
where m = slope
and c = y-intercept.
Since the y-axis represents the Gallons of water left in the tank.
The y-intercept represents the point which corresponds to when x = 0.
In this case, the y-intercept represents the amount of water that is initially in the water barrel. i.e 45gallons of water.

An orange juice can has a diameter of 4 inches and a height of 7 inches. The curved surface of the can is painted orange. How much paint is needed? Round your answer to the nearest tenth.
Answer: 88 in2
Step-by-step explanation:
The side of the can, which when "unrolled" is a rectangle, with width = height of the cylinder (7 in); and length = Circumference = 2π radius
Surface area of the curved surface of the can = 2π (diameter/2) x height
Replacing with the values given:
S = 2π (4/2) x 7 = 2π (2) x 7 = 88 in2

Which equations are correct? Select three options.
n = 10
n = 7
CF = 59
FE = 42
CD = 30
Answer: A, C, D
Step-by-step explanation: The other person accidentally put 49 instead of 42
The equations that are correct are n = 10, CF = 59 and FE = 42
Properties of a parallelogramFrom the attached diagram, we can see that the opposite side of the parallelogram are equal, hence;
DE = CF
6n - 1 = 5n + 9'
Find the value f n
6n - 5n = 9 + 1
n = 10
CF = 5n + 9
CF = 5(10) + 9
CF = 59
For the measure of FE
FE = 4n + 2
FE = 4(10) + 2
FE = 42
Hence the equations that are correct are n = 10, CF = 59 and FE = 42

Please help me find the surface area. Please explain, but not so its confusing like common core. Thanks.
Answer:
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Point C ∈ AB and AB=18 cm. The distance from C to A is 3 cm. shorter than the distance from C to B. Find AC and CB.
Answer:
AC=7.5 cm
CB=10.5cm
Step-by-step explanation:
Since we don't know the distance from C to B, we can label it as x. Our equation will be x+(x-3)=18. Simplify that so it is 2x-3=18. Add 3 to both sides and get 2x=21. x=10.5 So AC=7.5 cm and CB is 10.5 cm

324,000 cm3
540,000 cm3
Answer:
Step-by-step explanation:
upper block:
length (l) = 120 cm
Width (w) = 30 cm
Height (h) = 60 cm
Volume of upper block = l * w * h
= 120 * 30 *60
= 216,000 cm³
Lower Block
l = 120 cm
w = 30 cm
h = 30 cm
Volume of lower block = 120 * 30 * 30
= 108,000 cm³
Volume of steps = 216,000 + 108,000 = 324,000 cm³

Answer:
(A)A triangle with angles 45 degrees, 45 degrees, and 90 degrees. 2 sides are congruent.
Step-by-step explanation:
If Javier wants to construct a square by drawing two congruent triangles.
One of the angle of the triangle must be equal to 90 degrees to form one of the vertex of the square.The other two sides of the triangle must be equal(congruent) to form the two adjacent side lengths of the square. This gives rise to an Isosceles Triangle with base angles of 45 degrees each.Therefore, the triangle which could be used is a triangle with angles 45 degrees, 45 degrees, and 90 degrees.

A table has an area of 12 and a perimeter of 16 ft. What are the dimensions of the table?
A. 2 ft by 6 ft
B. 2 ft by 8 ft
C. 4 ft by 3 ft
D. 4 ft by 4 ft
｡☆✼★ ━━━━━━━━━━━━━━ ☾
As the area is 12, the length multiplied by the width must equal 12
Therefore, we can eliminate option B and option D as they wouldn't multiply to give 12
Let's test option A to see if it gives a perimeter of 16
2 + 6 + 2 + 6 = 16
As you see, this sums to 16
Thus, your answer is option A

y=x^{2} +4x-7 determine the axis of symmetry the vertex point and find the roots useing the QUADRATIC FORMULA
Answer:
Step-by-step explanation:
y=x²+4x-7
=x²+4x+4-4-7
=(x+2)²-11
axis of symmetry is x=-2
vertex is (-2,-11)
x²+4x-7=0
[tex]x=\frac{-4 \pm\sqrt{4^2-4(1)(-7)} }{2(1)} \\=\frac{-4 \pm \sqrt{16+28} }{2} \\=\frac{-4 \pm 2\sqrt{11} }{2} \\=-2 \pm\sqrt{11}[/tex]
Answer:
Axis of symmetry is x = -2
(-2, -11) is the vertex
Roots are
-2 + [tex]\sqrt{11}[/tex], -2 - [tex]\sqrt{11}[/tex]
Step-by-step explanation:
a) Axis of symmetry equation is: x = -b/2a
Original equation: y = [tex]x^2+4x-7[/tex]
So...
x= -4/2(1) = -2
Axis of symmetry is x = -2
b) Vertex Point can be found by plugging into original equation.
[tex]y =x^2+4x-7[/tex]
=> y = [tex](-2)^2+4(-2)-7[/tex]
=> 4 - 8 - 7 = y
=> -11 = y
(-2, -11) is the vertex
c) quadratic formula is [tex]x = \frac{-b +-\sqrt{b^2-4ac} }{2a}[/tex]
Lets plug in the values.
[tex]\frac{-4 +- \sqrt{4^{2}-4(1)(-7) } }{2(1)}[/tex]
[tex]\frac{-4 +- \sqrt{16+28 } }{2}[/tex]
[tex]\frac{-4 +- \sqrt{44 } }{2}[/tex]
[tex]\sqrt{44} = 2\sqrt{11}[/tex]
-4 +- 2[tex]\sqrt{11}[/tex]
--------------
2
Here, i will factor out 2, and take out the +- and make it into two equations
2(-2 + [tex]\sqrt{11}[/tex]) / 2 = -2 + [tex]\sqrt{11}[/tex]
2(-2 - [tex]\sqrt{11}[/tex]) / 2 = -2 - [tex]\sqrt{11}[/tex]
x= -2 + [tex]\sqrt{11}[/tex]
or
x = -2 - [tex]\sqrt{11}[/tex]
Roots are
-2 + [tex]\sqrt{11}[/tex], -2 - [tex]\sqrt{11}[/tex]

Ryan scored 87, 93, 96, and 89 on her first four history quizzes. What score does Ryan need to get on her fifth quiz to have an average of exactly 91 on her history quizzes?
Answer: For Ryan to get an average of exactly 91, she needs to get a 90 on her fifth quiz.
Step-by-step explanation:
You can find the average of a set of numbers by adding them together and dividing the sum by the amount of numbers added.
Ryan has five total quizzes. Only four of them are known, so we can represent her fifth quiz as X.
[tex]\frac{87 + 93 + 96 + 89 + x}{5}[/tex], dividing the five quizzes' sum by 5
She wants the average to be exactly 91, so you can set the expression equal to 91 and solve:
[tex]\frac{365 + x}{5} = 91\\\\365 + x = 455\\\\x = 90[/tex]
For Ryan to get an average of exactly 91, she needs to get a 90 on her fifth quiz.
