What is 5/16 written as a percent?

1 answer:

Rom4ik [11]3 years ago

7 0

First, you divide the fraction, and then you multiply it by 100.
So you get:
$\frac{5}{16} * 100$
$0.3125 * 100$
$31.25$

So, 5/16 is 31.25%

Hope this Helps! :)

Which line segment is not a diameter or radius of circle F?

spin [16.1K]

Short Answer: AB
Argument
Take F to be the center. The line segment that IS a diameter or radius must either go through F (that would make the line a diameter) or to be a radius the segment mus end in F and touch the circumference once. See below.

The diameter must not only go through F, it must touch the circumference in two places. EFB is a diameter. So is AFC

The radius must have 1 endpoint at the center and one endpoint on the circumference. DF is a radius.

So what isn't? Answer: AB isn't. It neither goes through F nor is F one of the end points.

Answer: AB

A solid metal cube of side 1-2 cm has a mass of 15 grams.

sashaice [31]

Answer:

The mass of the second cube is about 1085.07 grams.

Step-by-step explanation:

I assume '1-2 cm' means 1.2cm here. Correct me if I am wrong and I'll edit my answer.

First, find the density of this cube:

$d=\frac{m}{v}$

where d is density, m is mass, and v is volume.

We have one of those, but we also need volume. The volume of a cube is just:

$v=a^3$

where a is the length of a side.

$\rightarrow v=1.2^3\\\rightarrow v=1.728$

The volume of this cube is 1.728cm³. Now, you can find the density;

$\rightarrow d=\frac{15}{1.728}\\\rightarrow d\approx8.6806$

The density of this material is about 8.68 grams per cubic centimeter.

Finally, you can use that density to find the mass of the other cube. Fin the volume of the second cube:

$\rightarrow v=5^3\\\rightarrow v=125$

The volume is 125cm³. Given the density and the volume, you can calculate the mass:

$\rightarrow d=\frac{m}{v}\\\rightarrow 8.6806=\frac{m}{125}\\\rightarrow 8.6806\times125=m\\\rightarrow m=1085.0694$

The mass of the second cube is about 1085.07 grams.

At 2:00 PM a car's speedometer reads 30 mi/h. At 2:20 PM it reads 50 mi/h. Show that at some time between 2:00 and 2:20 the acce

storchak [24]

Answer:

The correct answer will be "60 min/hour".

Step-by-step explanation:

At time 2:00 PM

A car reads = 30 mi/h

At time 2:20 PM

A car reads = 50 mi/h

Now,

At time 2:00 PM

t = 0

At time 2:20 PM

t = $\frac{1}{3}$

$v(0)=30$

$v(\frac{1}{3})=50$

For MVT,

$v'(c)=\frac{v(\frac{1}{3} -v(0))}{(\frac{1}{3} )}$

$=\frac{20}{\frac{1}{3} }$

$=60 \ min/hour$

Answer:

1. The graph represents a proportional relationship

2. 70,000 miles

Step-by-step explanation:

1. The graph represents a proportional relationship since the graph line is straight and begins at the origin.

2. Plot 5.5 hours on the graph and it'll give you 70,000 miles
