Answer:
Concept: Number Analaysis
- The first option goes back 9 spaces hence
![4.3 \times {10}^{ - 9}](https://tex.z-dn.net/?f=4.3%20%5Ctimes%20%20%7B10%7D%5E%7B%20-%209%7D%20)
- Second one you to forward 10 spaces hence
![4.3 \times 10 ^{10}](https://tex.z-dn.net/?f=4.3%20%5Ctimes%2010%20%5E%7B10%7D%20)
- Using that logic solve the rest!
Since the triangles make up a spinner, the triangles are isosceles.
The base is 2 cm and the perimeter is 10 cm.
The measure of the two legs can be determined from
2 + 2x = 10
Where is the length of the leg
Solving for x
x = 4
The area an isosceles is calculated using
![A = \frac{1}{2} b^{2} \sqrt{ \frac{ b^{2} }{ x^{2} }- \frac{1}{4} }](https://tex.z-dn.net/?f=A%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20b%5E%7B2%7D%20%20%20%5Csqrt%7B%20%5Cfrac%7B%20b%5E%7B2%7D%20%7D%7B%20x%5E%7B2%7D%20%7D-%20%5Cfrac%7B1%7D%7B4%7D%20%20%7D%20)
where b is the length of the base
Substitute the values and multiply with the number of triangles in the spinner
Answer:
Graph the equation
Step-by-step explanation:
Answer:
1.5
Step-by-step explanation:
Because if you divide 30 by 20 you get 1.5 to check if it’s correct you multiple 1.5 by 20
