Answer:
The length of the equal sides is 15 centimeters.
Step-by-step explanation:
Since, base and height of the triangle are perpendicular to each other. In an isosceles triangle, the value of each equal length (
), measured in centimeters, can be determined by the following Pythagorean identity:
(1)
Where:
- Base of the triangle, measured in centimeters.
- Height of the triangle, measured in centimeters.
If we know that
and
, then the value of each equal length within the isosceles triangle is:
![l =\sqrt{\frac{(18\,cm)^{2}}{4}+(12\,cm)^{2}}](https://tex.z-dn.net/?f=l%20%3D%5Csqrt%7B%5Cfrac%7B%2818%5C%2Ccm%29%5E%7B2%7D%7D%7B4%7D%2B%2812%5C%2Ccm%29%5E%7B2%7D%7D)
![l = 15\,cm](https://tex.z-dn.net/?f=l%20%3D%2015%5C%2Ccm)
The length of the equal sides is 15 centimeters.
Answer:
Year 2: 109.4%
Year 3: 118.9%
Step-by-step explanation:
<h3>Given;</h3>
- Ash company reported sales of $580,000 for year 1
- $630,000 for year 2,
- $680,000 for year 3.
Now,
For the revenue trend percent for year 2
Year 2: $580,000 / $530,000 × 100 = 109.4%
For the revenue trend percent for year 3
Year 3: $630,000 / $530,000 × 100 = 118.9%
Thus, The answer is 109.4% and 118.9%.

Answer:
1. 52
2. 2.9
Step-by-step explanation:
To find the mean, we take all the numbers, add them up then divide by the number of numbers.
1. mean height
mean = (50+54+52+56+48)/5
=260/5
=52
52 inches
2. mean score
There are 5+3+12+2+6+6+4 students = 38 students
Multiply the number of students times the score and add together
total points = (0*5+1*3+2*12+3*2+4*6+5*6+6*4)
= 111
The mean is the total points divided by the number of students
mean = 111/38
=2.92
Answer:
Neither
Step-by-step explanation:
When you rearrange the equation 3x+2y=1 in the form of y=mx+c
you get:
2y=-3x+1
![y=-\frac{3}{2} x+0.5](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B3%7D%7B2%7D%20x%2B0.5)
And if you compare it with the equation y= -x -1
You can see that the gradient is not the same, so it means it is not parallel.
To get if it is perpendicular you need to see if the two gradients multiply to give the value -1 but when you multiply
×
so it is not perpendicular as well
I hope it is right, feel free to point out anything wrong or you're unsure of :)
Color in the model for each fruit. The number of squares colored is the percentage. If you put the number of squares colored over 100, you have the fraction. Then put the decimal point in front of the number.
Examples-
28 acres of apples-
28%
28/100 (This can be simplified)
0.28
5 acres of peaches
5%
5/100 (This can be simplified)
