The airline tickets to Jamaica that you want to buy just went on sale. They were originally $1100 and the sale price is $600. What percentage is the original price marked down?
Step-by-step explanation:
100% = $1100
1% = 100%/100 = 1100/100 = 11
how many % are $600 ?
that is how often does 1% fit into $600 ?
600 / 11 = 54.545454... %
rounded that means 55%.
so, the making down percentage is then the difference
100% - 55% = 45%
Hooke’s Law for an elastic spring states that the distance a spring stretches varies directly as the force applied. If a force of 180 newtons stretches a spring 5 cm, how much will a force of 270 newtons stretch the same spring?
Answer:
7.5m
Step-by-step explanation:
Set up a proportion and cross multiply to find the unknown
Hope this helps
The elongation of spring by 170 newtons force maintaining the given ratio is 7.5 cm.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given question,
Elongation of spring in 180 newtons = 5 cm
The ratio of elongation to force applied = 5/180
The force the second time is 270 newtons.
Let's say the elongation at this time is x cm.
The ratio of elongation to force applied = x/270
Both ratios must be the same.
Therefore, x/270 = 5/180
x = 270/36 = 7.5 cm
Hence "The elongation of spring by 170 newtons force maintaining the given ratio is 7.5 cm".

Answer:
57kg
Step-by-step explanation:
We need to find the length of each piece of metal:
We already know that 2 of them are 6m and 8m and this would be the same for the pieces of metal opposite.
So we have four lengths - 6m, 6m, 8m, and 8m
To find the last length, we need to use pythagoras theory
a² + b² = c² where c is the slanted side, or the diagonal
6² + 8² = c²
36 + 64 = 100
c² = 100
c = √100 = 10
So the five lengths are 6m, 6m, 8m, 8m, and 10m and the total is 38m
If:
1m = 1.5kg
38m = ?kg
We have to multiply both sides by 38
1m × 38 = 38m
1.5kg × 38 = 57kg
So, the total weight of metal in the frame is 57kg
write each of the following in the form of a x + B Y + C is equal to zero and find the values of a b and c
Step-by-step explanation:
(i) 2x = 5
compare with ax+by+c = 0
→ 2x + 0.y - 5 = 0
» a = 2 ,b = 0 ,c = -5
(ii) y - 2 = 0
compare with ax + by + c = 0
→ 0.x + 1y -2 = 0
» a = 0 , b = 1 , c = -2
(iii) y/7 = 3
y = 3×7
y = 21
y - 21 = 0
compare with ax + by + c = 0
→ 0.x + 1y -21 = 0
» a = 0 , b = 1 , c = -21
(iv). x = -14/13
13x = -14
13x + 14 = 0
compare with ax + by + c = 0
→ 13x + 0.y + 14 = 0
» a = 13 , b = 0 , c = 14

Factorise; 2 cubed multilpied by 2 squared.
[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Firstly let's change the statement to a numerical expression.
[tex] \cdot\sf \: 2 \: cubed = 2 ^{3} \\ \cdot\sf \: multiplied \: by = \times \\\cdot\sf \: 2 \: squared = 2 ^{2} \\ \\ \sf \: So, \: the \: expression \: becomes \rightarrow \boxed{\tt {2}^{3} \times {2}^{2} }[/tex]
__________________
[tex]2 ^{3} \times 2^{2} [/tex]
To solve this, we must know that while multiplying exponents which have a same base we must take their base as common & add the exponents.
[tex]2 ^{3} \times {2}^{2} \\ = (2) ^{3 + 2} \\ = \underline{\underline{ 2 ^{5} }}[/tex]
We got 2⁵. Now, multiply 2 five times to get the answer.
[tex] {2}^{5} \\ = 2 \times 2 \times 2 \times 2 \times 2 \\ = \huge \boxed{\boxed{\bf 32}}[/tex]

Hayami was riding her bike on a loop that is 15/16 mile long. she rode for 3/4 mile and then stopped to rest she rode another 1/8 mile and then has a flat tire. how far does Hayami have to walk her bike to complete the loop?
A.1/16 mile
b.1/32
c. 3/16
d. 1/8
1/16 mile
3/4 = 12/16
1/8 = 2/16
12/16 + 2/16 = 14/16
1/16 Mile left to walk
Hayami has to walk her bike Option A) 1/16 mile to complete the loop.
Hayami rode a total of 3/4 + 1/8 = 7/8 mile before getting a flat tire. To complete the loop, she needs to cover the remaining distance of the loop, which is
= 15/16 - 7/8
= 15/16 - 14/16
= 1/16 mile.
Thus, Hayami has to walk her bike 1/16 mile to complete the loop. Therefore, the correct answer is 1/16 mile.
To find out how far Hayami has to walk her bike to complete the loop, we need to calculate the remaining distance after she rode her bike before stopping for a rest and getting a flat tire.
1. First, we calculate the distance Hayami rode before stopping for a rest:
She rode 3/4 mile.
2. Then, we calculate the distance she rode after stopping for a rest but before getting a flat tire:
She rode 1/8 mile.
3. Now, let's find out the total distance she rode:
= 3/4 + 1/8
= 6/8 + 1/8
= 7/8 mile.
4. The length of the loop is \(15/16\) mile.
5. To find the remaining distance to complete the loop, subtract the distance she rode from the total loop length:
= 15/16 - 7/8
= 15/16 - 14/16
= 1/16 mile.
6. Therefore, Hayami has to walk her bike 1/16 mile to complete the loop.
In conclusion, the correct answer is 1/16 mile (Option A).

Eighteen plumbers can install 540 water lines in six weeks. How long will it take twelve plumbers to install the same number of lines?
It will take twelve (12) plumbers 9 weeks to install the same number of lines
From the question,
We have that, 18 plumbers can install 540 water lines in 6 weeks,
To determine how long it will take 12 plumbers to install the same number of lines,
First, we will determine how long it will take 1 plumber.
If 18 plumbers can install 540 water lines in 6 weeks
Then,
1 plumber will install 540 water lines in 18 × 6 weeks
18 × 6 weeks = 108 weeks
∴ It will take 1 plumber 108 weeks to install 540 water lines
Now, for the number of weeks it will take 12 plumbers
If 1 plumber can install 540 water lines in 108 weeks
Then,
12 plumbers will install 540 water lines in [tex]\frac{108}{12}[/tex] weeks
[tex]\frac{108}{12} = 9 \ weeks[/tex]
Hence, it will take twelve (12) plumbers 9 weeks to install the same number of lines

From the graph, write the linear equation in slope-intercept form
Answer:
y = -3x + 1
Step-by-step explanation:
slope intercept form -> y=mx+b
you can find your slope, m, by doing rise over run ( up 3, left one -> -3/1 )
you can find your y-intercept, b, by just looking at the y axis ( 0,1 -> 1 )
from there you just plug in the values
y = m ( slope ) x + b ( y-intercept )
y = -3x + 1
