A square and a equilateral triangle have the same perimeter the perimeter of the triangles is 12(z-2)cm.the perimeter of the square is 4x cm find the perimeter of each figure by writing and solving an equation for the variable of x. what is the value of x
<h2>SOLUTION</h2>- ➝ 12(x - 2) = 4x
- ➝ 12x - 24 = 4x
- ➝ 12x - 4x = 24
- ➝ 8x = 24
- ➝ x = 3
Therefore, the value of x is 3

Answer:
7.64% probability that they spend less than $160 on back-to-college electronics
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Probability that they spend less than $160 on back-to-college electronics
This is the pvalue of Z when X = 160. So
has a pvalue of 0.0763
7.64% probability that they spend less than $160 on back-to-college electronics
Answer:
Step-by-step explanation:
Given
Restrained Force
Increase in Kinetic Energy
Distance moved d=1.9 m
Work done by all the forces is equal to change in Kinetic Energy of Object i.e. by gravity force, Normal force and Applied Force
(b)In absence of applied force thus
work done by gravity will be equal to change in kinetic Energy
change in Kinetic Energy
