No she is wrong because product of a multiple of ten and a multiple of ten will not always be zero

It depends on what will always be zero. If the last digit is 0 with no value in front of it, then she's considered correct. If the last digit is 0 but it has a value (example: 20) in front of it, then she is considered incorrect.

Find the range of possible values for the following measurements, which were rounded to the nearest mm, tenth of m, and hundredt

zmey [24]

The required range of the data is 24mm

The range of data is the difference between the largest value and the least value in a set of data.

Since we are not given the range of data. Let's assume we gave the following data:

34mm, 30mm, 20mm, 44mm, 31mm

From the data

Highest measurement = 44mm

Least measurement = 20mm

Find the range

Range = Highest measurement - Least measurement

Range = 44mm - 20mm

Range = 24mm

Hence the required range of data is 24mm

<em>NB: The concept can be applied to any set of data given for other measurements in (b) and (c)</em>

David's bowling score is 6 less than 2 times Aaron's score. The sum of their scores is 84. Find the score of each student. Use t

Y_Kistochka [10]

Answer:

Aaron's bowling score is 30

David's bowling score is 54

Step-by-step explanation:

The variable representing Aaron's score is = a

The variable representing David's bowling score = d

The sum of their scores is 84.

= a + d = 84...... Equation 1

David's bowling score is 6 less than 2 times Aaron's score.

d = 2a - 6

Substituting 2a - 6 for d in Equation 1

a + 2a - 6 = 84

3a - 6 = 84

3a = 84 + 6

3a = 90

a = 90/3

a = 30

Hence, Aaron's bowling score is 30

d = 2a - 6

d = 2(30) - 6

d = 60 - 6

d = 54

David's bowling score is 54

The equation gives the speed at impact, V metres per second, of an object dropped from a height of h metres. SHOW WORK From what

devlian [24]

Answer:

h = 17.65 m

Step-by-step explanation:

The given equation gives the speed at impact :

$v=\sqrt{2gh}$

h is height form where the object is dropped

Put v = 18.6 m/s in the above equation.

$h=\dfrac{v^2}{2g}\\\\h=\dfrac{(18.6)^2}{2\times 9.8}\\\\h=17.65\ m$

So, the object must be dropped from a height of 17.65 m.

The ratio of dogs to cats at an animal shelter is 33 to 22. how many dogs are at the shelter if there is a total of 3030 animals

ss7ja [257]

I think you doubled them

ratio of dogs to cats=3:2

30 animals total

3+2=5 units
30=5unit
divide by 5
6=1unit

dogs=3 unit
6=1unit
times 3
18=3unit=dogs
