<span>Which expression can be used to determine the side length of the rhombus?
The answer is the first option: 10/Cos(30°) Explanation:
1. As you can see in the figure attached, there is a right triangle and its hypotenuse (which is represented with the letter "x") is the side you want to calculate. So, you have:
Cos(</span>α)=Adjacent leg/Hypotenuse
<span>
</span>α=30°
<span> Adjacent leg=(20 in)/2=10 in
Hypotenuse=x
2. When you substitute these values into the formula, you obtain:
</span>
Cos(α)=Adjacent leg/Hypotenuse
<span> Cos(30°)=10/x
3. Therefore, you obtain the expression to determine the side length of the rhombus by clearing the hypotenuse "x", as below:
x=10/Cos(30°)

Answer:
Step-by-step explanation:
Choose some values of x to plot. I usually start with zero:
5×0 + 5 = 5
Plot the point (0,5).
Then use x=-1, because it is the x- intercept:
5×(-1) + 5 = 0
Plot the point (-1,0).
Draw the line through both points.
Answer:
Krystal spent 7.33333 hours
Step-by-step explanation:
Ellie means that the amount spent can be represented in hours rather than minutes
1 hour = 60 minutes
X hour = 440 Minutes
X = 7 hours 20 minutes
Answer:
24% of 33.50 = 80.40
67% of 87.99 = 58.96 (rounded up from 58.9533)
6% of 8.75 = 0.53 (rounded up from 0.525)
Step-by-step explanation:
to find the persentage of a number, you can first devide the whole number by 100, then multiply by the persentage ur figuring out, heres an example
for 24% of 33.50. we first devide 33.50 by 100
<em>33.50 / 100 = 3.35</em>
then multiply by 24
<em>3.35 * 24 = 80.40</em>
note if there are three numbers before the decimal point, and ur working with cash, always round up t the nearest hundredth
