Answer:

<h3>0.0230 grams </h3><h3>0.804 inches </h3><h3>140 feet </h3><h3>509 kilometers</h3>

Step-by-step explanation:

The given choices are

0.0230 grams
0.035 ounces
0.804 inches
3.150 liters
140 feet
509 kilometers

Significant figures refer to digit numbers that actually mean something to the measure. For examaple, 0.0230 grams has three significant figures, because there are three digits that give information of the measure. But, 0.035 ounces doesn't have three significant figures, because only two digits give information.

Having said that, all numbers with three significant figures are

0.0230 grams

0.804 inches

140 feet

509 kilometers

All these number have three significant figures because they have three digits that offer information about the measure.

The number 3.150 liters has 4 significant figures, that's why it's not part of the answer.

Let z be the product of any 5 consecutive three digit odd natural numbers. When you multiply

Charra [1.4K]

Answer:

Step-by-step explanation:

If x is the middle number of the 5 consecutive odd numbers, their product is ...

x(x -2)(x +2)(x -4)(x +4) = x(x² -4)(x² -16) = x⁵ -20x³ +64x

The first 3-digit prime is 101, so the product of that with this is ...

101(x⁵ -20x³ +64x) = 101x⁵ -2020x³ +6464x

Since we're only interested in the units digit, we can find the mod 10 value of this to be ...

(x⁵ +4x) mod 10

Possible units digits of x are 1, 3, 5, 7, 9, so possible units digits of this product are ...

x(x⁴ +4) = 1(1⁴ +4) = 5

3(3⁴ +4) = 3(1 +4) = 5 . . . . mod 10

5(5⁴ +4) = 5(5 +4) = 5 . . . . mod 10

7(7⁴ +4) = 7(1 +4) = 5 . . . . mod 10

9(9⁴ +4) = 9(1 +4) = 5 . . . . mod 10

In every case, the units digit of 101z will be 5.

Draw and shade figures that represent 50%, 25%, and 150%. Label each figure and described it in words. How do I answer this ques

muminat

See photo for drawing.
Words:
Suppose a square is 100%,
50%: the square is divided into two equal parts, and one of them is shaded, therefore it is 50%.
25%: the square is divided into 4 equal parts, and one of them is shaded, therefore it is 25%.
150%: there are two squares, each divided into 2 equal parts, and 3 of them is shadowed, therefore it is 150%.
