The perimeter of triangle XYZ will be:
40r + 30r + 60r = 130r
The area of triangle ABC is n² so the area of triangle XYZ will be n²×r²
<span>9(w-4)-7w=5(3w-2)
(9w-36)-7w=15w-10
2w-36=15w-10
add 36
2w=15w+26
subtract 15w
-13w=26
divide by 13
-w=2 so w=-2</span>
Answer:
<h3>Finding averages.</h3><h3>Organizing data.</h3><h3>Estimating.</h3><h3>Data gathering.</h3>
Step-by-step explanation:
When we plan an effective budget, we certainly need to gather some data about the theme, which includes, prices, description of the stuff we need. Once we have the data we need, then we must organize it to set priorities, to make the budget effective.
Additionally, estiamting and finding averages are important skills, because we need to estimate how effective is the budget. In fact, maybe we would desing different budgets to compare them and analyse, using averages, which one is the most effective.
Answer:
5.8 m
Step-by-step explanation:
From the diagram given :
XY = opposite angle the angle. of depression = 30
To obtain the height YZ ;apply the trigonometric relation :
Tan θ = opposite / Adjacent
Tan 30° = YZ / 10
YZ = 10 * tan 30
YZ = 10 * 0.5773502
YZ = 5.77 m
The height is about 5.8 m
Answer:
f(0)=9
Step-by-step explanation:
f(x)= -5x+9
f(0)= -5(0)+9
f(0)= 0+9
f(0)= 9
