The number of paper newsletters the school needed is given by the equation A = 149.5
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of paper newsletters the school needed be A
Now , the equation will be
The percentage of parents who prefers newsletters electronically = 77 %
So , percentage of parents who prefers paper newsletters = 100 % - 77 %
The percentage of parents who prefers paper newsletters = 23 %
The total number of parents = 650
So , the number of paper newsletters the school A = percentage of parents who prefers paper newsletters x total number of parents
Substituting the values in the equation , we get
The number of paper newsletters the school A = ( 23/100 ) x 650
The number of paper newsletters the school A = 149.5
Therefore , the value of A is 149.5
Hence , the equation is A = 149.5

Tania has roll of cloth that is 52.5 feet long . She uses the cloth to make scarves that are each 3.75 feet long How many scarves can Tania make
Answer:
14 scarves
Step-by-step explanation:
Change the divisor 3.75 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.
We then have the equations:
5250 ÷ 375 = 14
and therefore:
52.5 ÷ 3.75 = 14
Both calculated to 0 decimal places.
A house worth £80,000 in January 2012 is set to decrease in value by 7% per year.
A more optimistic forecast suggests that the value of the house will increase by 4% per year. According to this forecast, how much will the house be worth in January 2015?
Answer:
The house would be worth £89989.12 in January 2015.
Step-by-step explanation:
With respect to the optimistic forecast, the value of the house will increase by 4% per year.
For the first year (January 2012 to January 2013),
4% of £80000 = 0.04 x £80000
= £3200
The cost of the house = £80,000 + £3200
= £83200
For the second year (January 2013 to January 2014), we have;
4% of £83200 = 0.04 x £83200
= £3328
The cost of the house = £83200 + £3328
= £86528
For the third year (January 2014 to January 2015), we have;
4% of £86528 = 0.04 x £86528
= £3461.12
The cost of the house = £86528 + £3461.12
= £89989.12
According to the forecast, the house would be worth £89989.12 in January 2015.

100th term for 5, 2, -1
Answer:
100th term = -1485
Step-by-step explanation:
Arithmetic Progressionthe nth term, Tn:[tex]t_{n} = a + (n - 1)d[/tex]
n = number of terms
= 100
a = first term
= 5
d = difference
= second term - first term
= 2 - 5
= -3
substitute the values into the formula
[tex]t_{100} = 5(100 - 1)( - 3)[/tex]
[tex]t_{100} = 5(99)( - 3)[/tex]

amir rented a dvd and it was due to be returned on 28 march he actually returned it to the shop on 16 april the rental shop applies 7p for everyday the dvd is overdue. Work out the total fine paid by amir give your answer in £
Answer:
£133
Step-by-step explanation:
March had 31 days
Extra days used in March = March 31 - March 28
= 3 days
Extra days used in April = 16 days
Total extra days used = Extra days used in March + Extra days used in April
= 3 days + 16 days
= 19 days
Cost per extra days = £7
Total fine for 19 extra days = £7 × 19
= £133
Total fine paid = £133
The total fine paid by amir should be £133.
The calculation is as follows:March had 31 days
Extra days used in March should be
= March 31 - March 28
= 3 days
Now
Extra days used in April = 16 days
And,
Total extra days used = Extra days used in March + Extra days used in April
= 3 days + 16 days
= 19 days
Cost per extra days = £7
Total fine for 19 extra days = £7 × 19
= £133

Find the value of x.

X+1
D
А Е

Х
С
A
x = [?]
Enter
Answer:
x = 2
Step-by-step explanation:
In the given figure
∵ ABC is a triangle
∵ D is a point on side AB
∵ E is a point on side BC
∵ DE // AC
∵ AC is the third side of the triangle
→ That means DE divides the sides AB, BC into parts that have the same ratio
∴ [tex]\frac{BD}{DA}[/tex] = [tex]\frac{BE}{EC}[/tex]
∵ BD = 6 and DA = 4
∵ BE = x + 1 and EC = x
→ Substitute them in the ratio above
∴ [tex]\frac{6}{4}[/tex] = [tex]\frac{x+1}{x}[/tex]
→ By using the cross multiplication
∵ 6 × x = 4 × (x + 1)
∴ 6x = 4(x + 1)
∴ 6x = 4(x) + 4(1)
∴ 6x = 4x + 4
→ Subtract 4x from both sides
∵ 6x - 4x = 4x - 4x + 4
∴ 2x = 4
→ Divide both sides by 2 to find x
∴ x = 2
what is the slope of the line that passes through the point (-1,-10) and (-1,-2). answer needs to be in simplest form
Answer: m = undefined
Step-by-step explanation:
-2-(-10) = 8
-1-(-1) = 0
m = 8/0
Which is an undefined slope
Answer:
The slope is undefined
Step-by-step explanation:
Plug in the points to the formula for slope (Formula Found Below). You would get (-2 + 10)/(-1 + 1), which simplifies to 8/0. Anything divided by 0 is undefined, which means that the slope is undefined.
Furthermore, you could also tell this simply by the points given. If two points on a line have the same x - coordinate, it means that the slope is undefined and that the line formed by the points isn't a function.
Formula for Slope:
[tex]\frac{y1 - y2}{x1 - x2}[/tex]
Usable with 2 points of the line given ((x1, y1) and (x2, y2))

What is m<3? Thank you
===================================================
Explanation:
Let
x = the measure of angle 2y = the measure of angle 3The goal is to find y
For now, focus on the interior angles of triangle DEF. We have these three angles:
D = 90 (due to the square angle marker)E = angle 1 = 53F = angle 2 = xThose interior three angles add to 180. This is true for any triangle.
D+E+F = 180
90+53+x = 180
143+x = 180
x = 180-143
x = 37
angle 2 = 37 degrees
Now we can find y.
Focus on angles 2 and 3, which are x and y respectively. These two angles add to 180 because they form a straight line. Note: the triangle's angles summing to 180 is closely related to this idea where angle 2 and angle 3 are a linear pair.
So this means,
(angle2)+(angle3) = 180
x+y = 180
37+y = 180
y = 180-37
y = 143
angle 3 = 143 degrees
It's not a coincidence that we ended up with a previously calculated value of 143. It turns out that adding the remote interior angles D and E leads to the exterior angle EFG.
D+E = 90+53 = 143 = angle EFG
I'm using the remote interior angle theorem. Some textbooks may call this the exterior angle theorem. In my opinion, the phrasing "remote interior angle theorem" is more descriptive.

Answer:
DJ = 48
Step-by-step explanation:
In triangle CDE, point J is the centroid.
Length of median DH = 72
By the property of the centroid of a triangle,
"Centroid of a triangle divides the medians in the ratio of 2 : 1"
By this property, length of DJ = [tex]\frac{2}{(2+1)}(DH)[/tex]
= [tex]\frac{2}{3}(72)[/tex]
= 48 units
Therefore, length of DJ = 48 units

Express "17 billion" in scientific
notation.
Answer:
The scientific notation is [tex]1.7\times 10^{10}[/tex].
Step-by-step explanation:
Consider the provided information.
We need to express 17 billion in scientific notation.
17 billion is: 17,000,000,000
We split the given number into a coefficient and a power of 10.
Move the decimal point of the given number till the coefficient of the given number is greater than 1 and less than 10 and write the power of 10 equal to the number of steps the decimal point was moved.
17 billion in scientific notation = [tex]1.7\times 10^{10}[/tex].
Hence, the required answer is [tex]1.7\times 10^{10}[/tex].
what is the correct prime factorization of 24?
Answer:
24= 2*2*2*3= 2^3*3
Step-by-step explanation:
Answer:
prime factorization of 24 = 2 * 2 * 2 * 3 = 2^3 * 3
Step-by-step explanation:
List the first several prime numbers: 2, 3, 5, 7, 11, 13, ...
Now start with 2. Divide 24 by 2 as many times as possible. Then move on to 3, to 5, etc. until you end up with 1.
Divide only by prime numbers.
Start by dividing 24 by 2:
24/2 = 12 12 is divisible by 2, so divide 12 by 2.
12/2 = 6 6 is also divisible by 2, so divide 6 by 2.
6/2 = 3 Since 3 is not divisible by 2, move onto 3.
3/3 = 1 When you get to 1, stop. The prime factors are all the prime numbers in boldface that you divided by.
prime factorization of 24 = 2 * 2 * 2 * 3 = 2^3 * 3
