Whats the product of (-3x+2y)(4x-y)
Answer:
-12x^2 + 11xy - 2y^2
Step-by-step explanation:
Answer:
-12x² + 11xy - 2y²
Step-by-step explanation:
To solve this:
You can distribute -3x to 4x
-3x*4x = -12x²
Then distribute the -3x to -y
-3x*-y = 3xy
Distribute the 2y to 4x
2y*4x = 8xy
Distribute the 2y to -y
2y*-y = -2y²
-12x² + 3xy + 8xy - 2y²
Combine like terms and add 3xy to 8xy
Final Answer: -12x² + 3xy + 11xy - 2y²

Which step is the same in the construction of parallel lines and the construction of a perpendicular line through a point on the line?
Answer:
D.Place the compass on a point on the original line.
Complete Question:
A.Create only one arc that intersects the original line.
B.Create two arcs that intersect the original line.
C.Place the compass on a point off the original line.
D.Place the compass on a point on the original line.
Step-by-step explanation:
* Lets revise the steps of constructing parallel lines and a perpendicular line through a point on the line
# Contracting parallel lines
- Given: Line AB and point P not on AB
1. Draw a slant line through point P and intersects AB at point C, this line is the transversal of the parallel lines
2. Place the pin of the compass at point C and draw an arc intersects AB at D and CP at E
3. Without changing the distance of the compass put the pin of the compass on point P and draw an arc intersects CP at point Q
4. Use the compass to measure the distance from D to E and place the pin of the compass at point Q and draw an arc intersects the arc from P to CP at point U
5. Join P and U by a line this line is parallel to AB
# Constructing a perpendicular line through a point on the line
- Given line AB and point P lies on it
1. Place your compass pin at P and draw an arc of any size below AB that crosses the line twice at points C and D
2. Stretch the compass to a larger distance
3. Place the compass pin on point C and draw a small arc above the line
4. Without changing the distance of the compass place the compass pin on point D and draw another arc intersects the arc from C at point E
5. Using a straightedge, join P and E where PE is perpendicular to AB
* Lets find the same steps in the constructions
∵ In first construction we put the pin of the compass at point C which lies in the original line AB
∵ In second construction we put the pin of the compass at point P which lies in the original line AB
∴ The common step is: "Place the compass on a point on the original line"
Answer:
just know the answer is not Create only one arc that intersects the original line.

¿Cuántos litros de agua se precisa para llenar una piscina inflable de 1/4 de metro cúbico?
Answer:
250 litters
Step-by-step explanation:
To solve this question, we first need to know the conversion from cubic meter to liter.
1 cubic meter is equal to 1000 liters.
So, if we have 1/4 cubic meter, we can use a rule of three to find how many liters we will need:
1 m3 -> 1000 L
1/4 m3 -> x L
x * 1 = (1/4) * 1000
x = 1000 / 4 = 250 L
So we need 250 liters of water.

a) Two triangles and a kite
Top triangle (1/2)(5.53)(1.5)
Bottom triangle (1/2)(6)(2)
The kite is like two triangles with shared base 2+3=5 and combined height 7,
(1/2)(5)(7)
Adding it up,
area = (1/2)(5.53)(1.5) + (1/2)(6)(2) + (1/2)(5)(7) = 27.6475
Answer: 27.6475 sq cm
b) Three triangles, including one right triangle
Area = (1/2) (6.7)(3) + (1/2)(6.2)(2.5) + 1/2(6.2)(2) = 24.

Answer:
AE Measure: 23.36 units
Step-by-step explanation:
BA: 20cm
BC:20cm
BE:10cm CE: 10cm
a^2 +b^2=c^2
BE^2 +BA^2 = AE^2
√100 + √400 = √500
AE^2 = √500 = 23.36
AE = 23.36 unit
Repeat effort :-)
Step-by-step explanation:
As ABCD is a square , BC = 20 cm
BE = 20/2 = 10 cm
Also , angle B = 90⁰
By pythagoras theorem :
AE² = 20² + 10²
AE² = 400 + 100
AE² = 500
AE = 10√5 cm

The best thing Anastasia can do to improve her creditworthiness is to pay down her student loan and credit card debt.
This will lower her credit utilization ratio, which is a significant factor in determining her credit score.
Having a high credit utilization ratio can indicate to lenders that she may be at risk of defaulting on her debts, which could make it more difficult for her to obtain a mortgage or other loans in the future.
Paying down her debts can help improve her credit score and make her a more attractive borrower to potential lenders.

At a school fair, students were challenged to hit one of the small congruent circles on the large rectangular board with a ball. Find the probability of hitting any small circle. Type answer as a percent. *
Answer:
The probability of a student to hit any small circle is 4.66 %.
Step-by-step explanation:
In order to determine the probability of the students to hit the small circles, we need to calculate the are of the rectangle and the area of each circle. These are shown below:
area circle = pi*r² = pi*(3)² = 28.26 in²
area rectangle = 35*52 = 1820 in²
Since there are three circles and the students can hit any of those the probablity of hitting them is given by the area of one circle multiplied by 3 and divided by the area of the rectangle.
p = [(3*area circle)/(area rectangle)]*100%
p = [(3*28.26)/1820]*100 = 4.66 %

The perimeter of a rectangular field is 342 m. If the width of the field is 76 m, what is it’s length?
Answer:
The length is 95 m
Step-by-step explanation:
P = 2(l+w) where l is the length and w is the width
342 = 2(l+76)
Divide each side by 2
342/2 = 2/2(l+76)
171= l+76
Subtract 76 from each side
171- 76 = l+76-76
95 = l

Answer:
Part B
This statement means that we are 95% confident that our confidence interval and our point estimate of our results from this sample contains the true proportion of national adults who fulfill a certain condition. The margin of error is plus or minus 4 percentage points in our survey, so we are fairly accurate / close to our point estimate.
Part C
Personally, I think that the minimum quota should be different, because nowadays very few people have landlines, and most people have cell phones. I would put it at 80% cell phones, 20% landlines, for the most representative survey possible.
Part D
Unfortunately, there isn't enough information to explain this one, because I can't see the link or view the responses and trends. I would give you the advice that you might want to include all variables and survey conditions: what type of survey was it? how many adults were sampled? what are your hypotheses or preconceived notions? what is the standard error? This should help; if not, please clarify.

Here is a pattern made from sticks:

//////////
////////////// How many sticks would be in pattern number 6?
b)
How many sticks would be in pattern number n?
Answer:
a) 26 sticks
b) an = 6 +4(n -1)
Step-by-step explanation:
You have patterns of sticks that have 6 sticks in the first pattern, 10 sticks in the second pattern, 14 sticks in the third pattern, and you want to know the number of sticks in the 6th pattern and in pattern number n.
b) Arithmetic sequenceYou have a sequence of patterns with 6, 10, and 14 sticks. The first pattern has 6, and the following patterns each have 4 more than the one previous. The sequence of numbers is an arithmetic sequence with a first term a1=6, and a common difference d=4.
The n-th term of such a sequence is given by the formula ...
an = a1 +d(n -1)
For the first term and common difference in this sequence, the number of sticks in pattern n is ...
an = 6 +4(n -1)
a) Sixth patternWhen n=6, the number of sticks is ...
a6 = 6 +4(6 -1) = 26
There would be 26 sticks in pattern 6.
