Answer:
Step-by-step explanation:
Pythagorean theorem,
hypotenuse²= base² + altitude²
base² = hypotenuse² - altitude²
x² = 14² - 9²
= 196 - 81
= 115
x = √115
x = 10.72
- 3.9 / 1.3 = - 3/1 = - 3
Calculation Steps:
Conversion:
3.9 = 39/10
Unary Minus:
- 3.9 = - 39/10
Conversion:
1.3 = 13/10
Divide:
- 39/10 : 1.3
= - 39/10 * 10/13
= - 39 * 10/ 10 * 13
= - 390/130
= - 3
Answer: - 3
Hope that helps!!!! Answer: - 3
Answer:
None of the answer options are correct
Step-by-step explanation:
cs + rh = w
cs = w - rh
s = (w - rh)/c
The second one could be corrected by exchanging c with 1/c
The last one would be correct with judiciously applied parentheses.
The first and third have too many errors to even bother trying to correct.
answer could also be written
s = w/c - rh/c
but it is not considered reduced form.
The answer is Not Proportional. I have this test too. Hope it helps!
If you're using log:
Swap both sides: 1100 · 1.7^n = 7000
Divide both sides by 1100: 1.7^n = 70/11
Concert decimal to a fraction: (17/10)^n = 70/10
Take the log of both sides. (Put 17/10 into the subscript of log like the picture shows)
The answer is the decimal.
