Answer:
7cm
Step-by-step explanation
If O is the middle of the rhombus then you just add PO to OQ
PO + OQ = PQ
4+3 = 7
Answer:
PQ is gonna be the same as whatever is opposite of it
Answer:
49°

I hope it helps
Answer:
yeah im pretty sure you are
Step-by-step explanation:
Answer:
the last one is the correct answer
Step-by-step explanation:
In order for it to be proportional it has to go through the origin (0,0)
Proportional - y=mx
Non Proportional - y=mx+b
9 × 10-4
90 × 10-4
9 × 10-6
9^ -2
9^ 8/9^4
9^8/9^10
9^ -6 · 9^3
9^5 · 9^ -7
Answer:
Step-by-step explanation:
Let's evaluate the answers.
Think of numbers with negative exponents as numbers on the wrong side of the fraction. So if you have a negative exponent, you put it at the bottom of the fraction or up and then you remove the negative sign.
So let's take the first answer:
Now the next one, according to the law of exponents, when dividing we subtract the exponents. (But this only applies if the coefficients are the same!)
Applying this rule to the second answer:
The third one:
If you apply the same rules to the rest of the choices, you wil find that they are not equivalent to 1/81.
The expressions that are equivalent to 1/81 are , , and .
To determine which expressions are equivalent to 1/81, we can simplify each expression and check if it equals 1/81.
: This expression is equivalent to 1/8, not 1/81. Therefore, it is not equivalent.: This expression is equivalent to 1/9², which simplifies to 1/81. Therefore, it is equivalent to 1/81. : This expression simplifies to , which is not equal to 1/81. Therefore, it is not equivalent.: This expression simplifies to , which is equivalent to 1/9². Therefore, it is equivalent to 1/81.: This expression simplifies to . Therefore, it is not equivalent.: This expression simplifies to , which is equivalent to 1/9². Therefore, it is equivalent to 1/81.Thus, the expressions that are equivalent to 1/81 are , , and .
