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
At least two teachers must accompany every five elementary students on a field trip. If 45 students are going
on the trip, what is the minimum number of teachers needed?
Answer:
9
Step-by-step explanation:
divide 5 into 45 which equals 9
Answer:
The minimum number of teachers needed for this trip is 18.
Step-by-step explanation:
The slope for this is 5/2. So the equation is y = (5/2)x. We know the y is 45 students. So we do division. In the end, we get x = 18 teachers.
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.
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

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

Answer:
266 2/3 : 333 1/3 : 400
Step-by-step explanation:
The total of ratio units is 4+5+6 = 15, so the fraction of 1000 that each portion represents is ...
4/15 : 5/15 : 6/15 = 4/15 : 1/3 : 2/5
Multiplying 1000 by these fractions gives ...
1000(4/15) : 1000/3 : 1000(2/5)
= 266 2/3 : 333 1/3 : 400

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]
[tex]t_{100} = 495( - 3)[/tex]
[tex]t_{100} = - 1485[/tex]
Select the FALSE statement
A) Dilations either increase or decrease the lengths of line segments.
B) Dilations increase angle measures.
C) A dilated triangle is similar to the original triangle.
D) Dilations are a type of transformation
9514 1404 393
Answer:
B) Dilations increase angle measures.
Step-by-step explanation:
Dilations have no effect on angle measures, but they uniformly change the size and spacing of line segments. They are a non-rigid transformation that leaves geometric figures similar to the original.
The false statement is B.

Ms. Emily buys a hat and gloves with a coupon for 30% off her entire purchase. The glove cost $35 before the discount. Her bill before tax is 44.80
Answer:
Step-by-step explanation:
Okay, I'm assuming you want us to figure out how much the hat costs.
To start off, let's figure out how much the gloves cost after the discount. 35 / 100= 0.3. We multiply that by 70%, since that is how much of the price is going to be left over after deducting 30%. We get $24.50.
So;
$44.80 of the total bill - $24.50=$20.30.
So we now know the hat cost $20.30.

Answer:
x = 4
Step-by-step explanation:
7x + 16/11 = 4
11 x 7x + 16/11 = 4 x 11
7x + 16 = 44
7x + 16 - 16 = 44 - 16
7x = 28
7x/7 = 28/7
x = 4
Check:
7x + 16/11 = 4
7(4) + 16/11 = 4
28 + 16/11 = 4
44/11 = 4
4 = 4 (note that this number is not the answer, just to check if each side is balanced, the actual answer is 4)

At a lemonade stand, pink lemonade costs $2.50 and sweet tea lemonade costs $4. In one morning, the stand sells 21 drinks for $67.50. How many pink lemonades were sold?
Answer:
lemonade = 11
Step-by-step explanation:
let p = pink lemonade
let t = sweet tea
create a system of equations -- one with quantity, one with associate costs
p + t = 21
2.5p + 4t = 67.5
substitution method: let t = 21 - p
2.5p + 4(21 - p) = 67.5
2.5p + 84 - 4p = 67.5
-1.5 p = -16.5
p = 11
t = 21 - 11
t = 10

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.

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.
