Answer:

Yes its true.

Step-by-step explanation:

35 + 70 = 105

35 (1+2) First you have to solve what is in the parentheses first, (1+2)=3. So now that problem is 35(3) or 35 x 3.

35 x 3 = 105.

Sorry, I'm not the best at explaining but I hope this helps.

43/14 as decimal rounded to nearest hundredth

anzhelika [568]

Answer:The answer would be 3.07.

I divided 43 and 14 and got 3.07143 and then since you said nearest hundredth I just went from left to right and skipped 2 decimals and cut it and kept 3.07.

Hope this helps!

Josue broke a cell sample into 12 batches, each weighing 6.9 x 10 ^-10

Klio2033 [76]

Using proportions, it is found that the original sample weighed $8.28 \times 10^{-9}$ grams.

This question is solved by <em>proportions</em>, using a rule of three.

The weight of 1 batch, in grams, is of $6.9 \times 10^{-10}$ . How much do the sample of 12 batches weigh?

The rule of three is:

1 batch - $6.9 \times 10^{-10}$ grams.

12 batches - x grams

Applying cross multiplication:

$x = 12 \times 6.9 \times 10^{-10} = 82.8 \times 10^{-10}$

Applying scientific notation:

$8.28 \times 10^{-9}$

The original sample weighed $8.28 \times 10^{-9}$ grams.

Max completed 12 questions on the exam. This is 40% of the questions. 1. Write an equation representing this situation. 2. How m

Marrrta [24]

Answer:

Step-by-step explanation:

How many questions are on the exam? Represent this by n.

Then 40% of n comes out to 12 questions, or more symbolically,

0.40n = 12, after which we get n = 12/0.40 = 30

Answers:

(1) 0.40n = 12 is the desired equation.

(2) n = 30 is the number of questions on the exam.

(3) See above for explanations.
