Answer: -9^5 = -59049
Step-by-step explanation: you would just multiply -9 by 5.
30 × 100 = 3,000, 30 × 10³ = 30,000 and 30 × 1000 = 30000. Therefore, options A, B, C and D are the correct answers.
<h3>What is an equation?</h3>
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
A) 30 × 100 = 3,000
Here, LHS = RHS
B) 30 × 10³ = 30,000
Here, LHS = RHS
C) 30 × 1000 = 30000
Here, LHS = RHS
D) ![30 \times 10^4 = 3000](https://tex.z-dn.net/?f=30%20%5Ctimes%2010%5E4%20%3D%203000)
30 × 10000 = 300,000
Here, LHS ≠ RHS
E) 30 × 10000 = 30,000
= 300,000
Here, LHS ≠ RHS
Therefore, options A, B, C and D are the correct answers.

Answer:
G. 15%
Step-by-step explanation:
because 60-45= 15 or if you figure out what you need to add to 60 to get 100 and add that to 45 you get 100-85=15
The answer is the last choice
We have been given that in ΔSTU, the measure of ∠U=90°, ST = 9.7 feet, and US = 4 feet. We are asked to find the measure of ∠T to the nearest degree.
First of all, we will draw a right triangle using our given information.
We can see that US is opposite to angle T and ST is hypotenuse of right triangle.
We know that sine relates opposite side of right triangle to hypotenuse.
![\sin=\frac{\text{Opposite}}{\text{Hypotenuse}}](https://tex.z-dn.net/?f=%5Csin%3D%5Cfrac%7B%5Ctext%7BOpposite%7D%7D%7B%5Ctext%7BHypotenuse%7D%7D)
![\sin(\angle T)=\frac{US}{ST}](https://tex.z-dn.net/?f=%5Csin%28%5Cangle%20T%29%3D%5Cfrac%7BUS%7D%7BST%7D)
![\sin(\angle T)=\frac{4}{9.7}](https://tex.z-dn.net/?f=%5Csin%28%5Cangle%20T%29%3D%5Cfrac%7B4%7D%7B9.7%7D)
Now we will use arcsin to solve for measure of angle T as:
![\angle T=\sin^{-1}(\frac{4}{9.7})](https://tex.z-dn.net/?f=%5Cangle%20T%3D%5Csin%5E%7B-1%7D%28%5Cfrac%7B4%7D%7B9.7%7D%29)
![\angle T=24.353873017978^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20T%3D24.353873017978%5E%7B%5Ccirc%7D)
Upon rounding to nearest degree, we will get:
![\angle T\approx 24^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20T%5Capprox%2024%5E%7B%5Ccirc%7D)
Therefore, the measure of angle T is approximately 24 degrees.
