2 answers:

3 0

The answer is C.

33,21,and 15 are all composite numbers. Meaning that they had factors other than 1 and themselves. 13 is a prime number because 13 only factors are 1 and itself.

<span>C. 6 + 7 = 13</span>
because 6 and 7 are consecutive integers, but 13 is not a composite number.

Find the value of x

Karo-lina-s [1.5K]

Answer:

x = 68°

Step-by-step explanation:

∠ DCB = ∠ EDC = 27° ( alternate angles )

Thus ∠ ECB = 23° + 27° = 50°

The sum of the 3 angles in a triangle = 180°, thus

x = 180° - (62 + 50)° = 180° - 112° = 68°

Whats the density of an object with the length of 5.0 cm a height of 3.0 and width of 15.0 cm and a mass of 24 grams

Sphinxa [80]

Answer:

The density of the object is $0.1067$ grams per cubic centimeter. (Rounded off to 4th decimal)

Step-by-step explanation:

Density = [Mass/Volume]

Here we have been given the dimensions of the object.

Volume = Height * Width * Length

Volume = $3.0cm*15.0cm*5.0cm$

= $225cm^{3}$

Now we can substitute the Mass and the Volume to the density equation.

Density = [Mass/Volume]

= $\frac{24grams}{225cm^{3} }$

= $0.1067$ grams per cubic centimeter. (Rounded off to 4th decimal)
