Estimate then record the product $473x9

Answers

So because 9 and 10 are close to each other, and the fact that 10 is really easy to multiply by, you do 473 x 10 which is 4730, because you just add a 0 to the end.
This means that an estimate is 4730 or if you want to be less specific, <4730, because 9 is less than 10.
The actual product though is 4257.

the Answer is 4,267
473 times 9 is 4,267 because u always multiply the number that is below the number that u are multiplying 4,267 times 9. 9 times 7 is 27 9 times 7 is 64 plus 2 is 66 and 9 times 4 is 36 so always multiply that small number with the numbers that is bigger

Three fifths of the members of a hiking club went on the last hiking trip. If 39 people went on the trip , how many are in the club?

Answers

Step-by-step explanation:

1. Since 39 is 3/5 of the club, divide by 3 to get 1/5 of the club

2. 1/5 of the club is 13 people

3. Multiply 13 by 5 to get 5/5 of the club (which is the whole club)

4. The whole club is 65 people

5. You can check it because 65×3/5=39

Factor completely. x^2−12x+35

Answers

Answer:

(x-5) (x-7)

Step-by-step explanation:

x²−12x+35

note that the constant term is 35 and the x-coefficient is -12

step 1: List factors of 35 : ±1, ±5, ±7,±35

step 2: observe the factors listed and ask ourselves the following questions:

1) What 2 factors in the list , when multiplied gives the constant 35

2) What same 2 factors when added gives the x-coefficient -12

by deduction or trial and error, we can see that -5 and -7, when multiplied gives 35 and when added gives -12. Hence these become the factors.

Hence the factors are

(x-5) (x-7)

How do I write 1.75 as a mixed number in simplest form?

Answers

Since the 5 is in the hundredths place then, the denominator would be 100. 1 is the whole. 75 would be the numerator. So the mixed number would be 1 75/100. When you simplify 75/100 by 25, your final answer including the whole number would be 1 3/4

You would write it one and thirty four hundreths
