<h3>Answer: See the diagram below</h3>
Explanation:
In the LS column, you'll have these steps
3x - 1
3*4 - 1
12 - 1
11
Effectively, we replaced x with 4 and then simplified using PEMDAS.
And in the RS column, you'll have these steps
x + 7
4 + 7
11
We get the same thing at the bottom of each column. This shows that we end up with 11 = 11 after simplifying both sides. Therefore, we've confirmed that x = 4 is the solution to 3x - 1 = x + 7
Answer:
80.94 cm squared
Step-by-step explanation:
The area of a parallelogram is: A = bh, where b is the base and h is the height perpendicular to the base.
Right here, we see that we're given two different possible bases: 8.9 and 11.4. However, when we look at the height, it's perpendicular to the base with length 11.4, so we know to disregard the base with length 8.9 and only focus on the 11.4. Then b = 11.4 and h = 7.1. So, the area is:
A = 11.4 * 7.1 = 80.94
Thus, the answer is 80.94 cm squared.
Hope this helps!
Answer:
The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.Step-by-step explanation:
The cosine of an angle is equal to the ratio of the length of the adjacent side and the length of the hypotenuse. In equation form:
cos x = BC / y
Solving for BC
BC = y cos x
BC is the distance between the Earth and the sun
Find the z-score for both 75% and 82% then subtract them.
Z-score for 75%:
75 -75 /7 = 0-7 = 0
Using empirical rule, This translates to a percentile if 50%
Z-score for 82%
82-75 /7 = 7/7 = 1
Using empirical rule, this translates to 84.13%
Answer = 84.13-50 = 34.13% round to 34%
