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".

Ben and Mack stopped at a restaurant to eat. Ben purchased 2 hot dogs and 2 drinks for $4.75. Mack purchased 3 hot dogs and 1 drink for
$7.75. Which system of equations can be used to determine the price of each hot dog, x, and each drink, y?
A. 2x + 2y = 4.75
3x + y = 7.75
OB. 2x + 2y = 7.75
3x + y = 4.75
OC. X + 2y = 7.75
2x + 3y = 4.75
D. x + 2y = 4.75
2x + 3y = 7.75
Answer:
A is the answer
Step-by-step explanation:
Let x equal hotdogs and y equal drinks
2 hotdogs plus 2 drinks = 4.75
3 hotdogs plus 1 drink = 7.75

The 6 elephants at the zoo have a combined weight of 11,894 pounds. About how much does each elephant weigh?
Answer:
1982.33 pounds
Step-by-step explanation:
If they all weigh the same amount then you can figure it out by division.
11894/6=1982.33
Answer:
TO find out how much each elephant weighs you simply have to do 11, 894 divided by 6. Since the answer is a decimal (1982.33333333), I would just round it to the nearest tenth as it dosent specify where we have to round it to. SO, 1982.33333333 rounded to the nearest tenth is 1982.3

is 5(1/5^3) = 5(5^3)
Answer:
5(1/5^3) ≠ 5(5^3)
Step-by-step explanation:
5(1/5^3) = 5(5^3)
5/27 = 625
5(1/5^3) ≠ 5(5^3)
The sides aren't equal, so this equation is FALSE.
Answer:
Step-by-step explanation:
Short answer: No they are not the same.
5 * 1/5^3 = 1/5^2. One of the 5s in the denominator cancels out.
5^1 * 5^3 = 5^(1 + 3) = 5^4. Nothing cancels here. The powers add.

Since BC is longer than AB, this means m<bcd is smaller than m<bad.
A way to prove it mathematically is to look at the triangle on the left. Since It's an isosceles triangle, m<cda and m<dac are equal. However, the triangle on the right does not have two proven congruent sides. All we know is BC is larger than the other side lengths. In a figure like that, the obtuse angle that meets the longest side would be the largest angle.
