3.604m + 104.29m + 3.1m + 17.41m. The sum expressed in the correct number of significant figures is
dedylja [7]

Answer:

128.4 m

Explanation:

3.604m + 104.29m + 3.1m + 17.41m

Add all the values

= 128.404 m

The significant figure rule for addition is for the sum to have the same number of decimal places as the value with the least number of decimal places. In the addition sentence 3.604m + 104.29m + 3.1m + 17.41m, the value with the least number of decimal places is 3.1, which has 1 decimal place. Therefore, we round our sum so that it also has 1 decimal place.

128.404 m

= 128.4 m

What is the wavelength of a sound wave moving at 340 m/s with a frequency of 256 Hz?
777dan777 [17]
The  wavelength  of  a sound  wave  moving  at 340  m/s  and   with  a frequency of  256  Hz   is  calculated using the  the below  formula

wavelength =  speed  of the  wave/frequency

speed  of  the  wave = 340 m/s
frequency = 256 Hz

wavelength  is therefore =  340/256 =  1.32 m

Help!!<br> Classify each diagram as an element a compound or mixture
Black_prince [1.1K]

Answer:

1. Mixture

2. Compound

3. Compound

4. Element

Explanation:

Number 1 shows two completely different types of compounds in the same space, so it is a mixture.

Numbers 2 and 3 are compounds because there aren't different types compounds as in Number 1, but the same compound repeated. 2 is a compound because while all of the circles are the same element, they are connected. O2 for example, oxygen, is a compound.

Number 4, finally, is all of the same substance, non-connected, so it shows an element.

Brainliest, please :) (Trying to become a genius so that I can continue helping more people)
