Answers
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
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 £
Answers
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 slope given the two points below:
(-8, — 11), (-1, 17)
Answers
Answer:
Slope: 4
Step-by-step explanation:
Answer: The slope is 4
Step-by-step explanation:
Slope formula:
[tex]m = \frac{y_{2}-y_{1} }{x_{2}- x_{1} }[/tex]
[tex]m = \frac{17 - (-11) }{-1 -(-8) }[/tex]
[tex]m = \frac{17 +11 }{-1 +8}[/tex]
[tex]m = \frac{28 }{7}=m = \frac{4}{1}=m =4[/tex]
m = 4
The slope 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?
Answers
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

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]

what is the correct prime factorization of 24?
Answers
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

===================================================
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.

Answers
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.

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
Answers
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?
Answers
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.
