Passing is a good goal.

pH = -log H+

7.2 = -log H+

-7.2 = log H+

10^(-7.2) = H+

Answer: H+ = 10^(-7.2), third choice

How do you show less than or equal too on a number line?

NISA [10]

It is like if you have two number lines. Then one has a pointer at 0, and the other one has the pointer facing at 2 then it will be lesser because the first one has 0 or if it turned around it would be greater. If it is equal then it would have the same number, but watch out if it is a negative number.

A wheel assembly is

Basile [38]

Answer:

The total weight of the assembly is 7 pounds.

Step-by-step explanation:

The total weight of the assembry is found by the sum of the weights of each components.

We have:

2 wheels, each weighing 2.6 pounds, so 2*2.6 = 5.2 pounds

An axle, which weighs 1.8 pounds, so 5.2+1.8 = 7 pounds

The total weight of the assembly is 7 pounds.

HELP I NEED THIS DONE QUICKK CAN ANNYONE HELP???????????????????????????????????????????????????????????????????????????????????

For the first question, it would be D: $\frac{1}{3}$ ÷ 9. This is because to solve a division problem with fractions, you would need to multiply the first fraction by the reciprocal of the second fraction. For the second question, the answer would be D: 32. This can be solved by dividing 8 by $\frac{1}{4}$ or 0.25. For the third question, it would be D. $\frac{1}{12}$ . This can be solved by dividing $\frac{1}{4}$ by 3. For the fourth question, the answer would be $\frac{1}{12}$ . This can be found by flipping the 4, which would make it look like $\frac{1}{4}$ , and multiplying it by $\frac{1}{3}$ . For the last question, 1 would be B, 2 would be C, 3 would be C, and 4 would be A.

Hope this helps ^-^
