We can use the formula density mass over volume to find the density of a substance square metal plate has a density of 10.7 g of

sweet-ann [11.9K]

Answer: The volume of given substance is $2.2 cm^{3}$ .

Step-by-step explanation:

Given: Density = 10.7 $g/cm^{3}$

Mass = 23.54 g

Density of a substance is the mass of substance divided by its volume.

Mathematically, $Density = \frac{mass}{volume}$

Substitute the values into above formula to calculate volume as follows.

$Density = \frac{mass}{volume}\\10.7 g/cm^{3} = \frac{23.54 g}{volume}\\volume = \frac{23.54 g}{10.7 g/cm^{3}}\\= 2.2 cm^{3}$

Thus, we can conclude that the volume of given substance is $2.2 cm^{3}$ .

Raymond has $800 in a savings account that earns 10% interest per year.The interest is not compounded. How Much Interest Will He

Gennadij [26K]

The amount of interest he would earn in one (1) year is equal to $80.

<u>Given the following data:</u>

Interest rate = 10% = 0.1

Principal = $800

Time = 1 year

To determine how much interest he would earn in one (1) year:

<h3>How to calculate simple interest</h3>

Mathematically, simple interest is given by this formula:

$I = PRT$

<u>Where:</u>

S.I is the simple interest.

P is the principal or starting amount.

R is the interest rate.

T is the time measured in years.

Substituting the given parameters into the formula, we have;

$I=800 \times 0.1 \times 1$

Simple interest = $80

There were 137 adult dusky gopher frogs in 2014. The number of adult dusky gopher frogs has grown about 9% per year since then.

Neporo4naja [7]

Answer:

273 frogs.

Step-by-step explanation:

The equation of growth in the number of frogs N = 137(1.09)^t where t is the time in years.

The year 2022 is 8 years after 2014 so the prediction for N in 2022 is:

N = 137(1.09)^8 = 273.
