If 12 roses cost 30.4 how much will 18 roses cost?
Answer:
45.6
Step-by-step explanation:
We can write a proportion to solve
12 roses 18 roses
------------ = -----------
30.4 x
Using cross products
12x = 30.4 * 18
12x=547.2
Divide each side by 12
12x/12 = 547.2/12
x = 45.6

what is the slope of a line parallel to the line whose equation is 3x - 2y = 18
Answer:
3/2
Step-by-step explanation:
3x - 2y = 18
y=(3/2)x-9
Slope of the given line=3/2
As parallel lines have same slope, slope of the line parallel to the line 3x - 2y = 18 is 3/2.
Hope it helps :)
Slope of a line parallel to the line whose equation is 3x - 2y = 18 is 3/2.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Two lines are said to be parallel when their slopes are same.
To find the slope of parallel line, we need to find slope of 3x - 2y = 18
3x-2y=18
-2y=18-3x
y=-18/2+3/2x
y=3/2x-18/2
Slope of line is 3/2
Hence, slope of a line parallel to the line whose equation is 3x - 2y = 18 is 3/2.

In the figure it is impossible to measure segment AB. So point C is drawn, forming ∆ABC, where sides AC and BC can be measured. Segments AC and BC are extended, resulting in segments AD and BE, where C is the midpoint of both. Prove ED is congruent to AB.
△ABC≅△___ by reason _____ (AAA, ASA/SAA, Cannot Be Determined, SAS, SSS)
Answer:
Step-by-step explanation:
From the given picture,
AD and BE are the lines intersecting at a point C.
Point C is the midpoint of these lines.
From ΔABC and ΔDEC,
AC ≅ CD
CE ≅ CB
And ∠ABC ≅ ∠DEC [Vertical angles]
Therefore, ΔABC ≅ ΔDEC [By SAS property of congruence]
And AB ≅ ED [Since, ΔABC ≅ ΔDEC]
What is the perimeter, in units, of polygon EFGHJK?
Answer:
38 units.
Step-by-step explanation:
Perimeter of the polygon EFGHJK = 38 unit
What is perimeter?Perimeter of a shape is defined as the total length of its boundary. The perimeter of a shape is determined by adding the length of all the sides and edges enclosing the shape. It is measured in linear units of measurement like centimeters, meters, inches, or feet.
Given,
In graph of polygon EFGHJK
EF = 2 unit
FG = 10 unit
GH = 9 unit
HJ = 8 unit
JK = 7 unit
KE = 2 unit
Perimeter of EFGHJK = EF + FG + GH + HJ + JK + KE
= 2 + 10 + 9 + 8 + 7 + 2
= 38 unit
Hence, 38 unit is the measure of perimeter of polygon EFGHJK.

What is the Y intercept of the line graphed on the grid
Answer:
5.5
Step-by-step explanation:
The y-intercept of the line graph shown above is the value of the point where the line cuts the y-axis. The y-intercept of this graph is between 5 and 6. However, we can get an accurate value by calculation. This can be done by generating an equation of the line.
Recall the slope-intercept equation, [tex] y = mx + b [/tex], where m = slope of the line, b = y-intercept.
To generate the equation of the line, first find slope using the points (-2, 7) and (6, 1):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 7}{6 -(-2)} = \frac{-6}{8} = -\frac{3}{4} [/tex].
Substitute m = ¾ and the coordinates (6, 1) into the slope-intercept equation to find the y-intercept (b):
[tex] y = mx + b [/tex]
[tex] 1 = -\frac{3}{4}(6) + b [/tex]
[tex] 1 = -\frac{18}{4} + b [/tex]
[tex] 1 = -4.5 + b + 4.5 [/tex]
[tex] 1 + 4.5 = -4.5 + b + 4.5 [/tex]
[tex] 5.5 = b [/tex]
Therefore, b = y-intercept = 5.5.
To generate the equation of the line, plug in the values of m and b, we would have:
y = ¾x + 5.5
The y-intercept of the line of the graph is 5.5.

Use the properties of operations. a. The Commutative Property is true for addition. For example, 7+2= 2+7. Does the Commutative Property apply to subtraction? Is 2-7 equal to 7-2? Explain.
Step-by-step explanation:
Commutative property of addition is a+b=b+a
7+2=9 , 2+7=9

Answer:
42
It was on my test I put 42 a day later i checked my test the answer was correct. Sorry that I didn't really have a explanation.
But at least its correct.
Ms. Smith still have 42 ounces of candy in her bag.
What is Subtraction?To subtract means to take away from a group or a number of things.
Given that Ms. Smith bought a 5 pound bag of candy for her 6th grade classroom. She gave away 2 pounds of candy to her students during the first unit of instructions and ate 6 ounces of candy during planning.
1 pound = 16 ounces
She gave away 2 out of 5 pounds, so she is left with 5 - 2 = 3 pounds
3 pounds = 16*3 ounces = 48 ounces
She ate 6 ounces of candy
Therefore, she now has, 48 - 6 = 42 ounces of candies left with her.
Hence, Ms. Smith still have 42 ounces of candy in her bag.

Suppose you scored an 80 on a measure where the mean is 65 and the standard deviation is 5. How many standard deviations from the mean is your score
Answer:
The score is 3 standard deviations from the mean
Step-by-step explanation:
To find this, we simply calculate the z-score
Mathematically;
z-score = (x-mean)/SD
In this question , x = 80
mean = 65
SD = 5
Thus;
z-score = (80-65)/5 = 15/5 = 3
