Answer:

d.8.63 g/ml

Step-by-step explanation:

Hello

In physics the density is a scalar magnitude referred to the amount of mass in a given volume of a substance or a solid object.it is given by:

density =\frac{mass\ of\ the\ object}{volume\ of\ the\ object} \\

Step 1

Find the volume of the object

According to the question

(Eq1)Volume of water=48.4 ml.

(Eq2)Volume of water+volume of the solid=62.7 ml

(Eq3)Mass of the object = 123.4 g

Now, from (Eq2) find volume of the solid

(Eq2)Volume of water+volume of the solid=62.7 ml

subtract volume of water on both sides

Volume of water+volume of the solid-Volume of water=62.7 ml-Volume of water

hence

(Eq4)volume of the solid=62.7 ml-Volume of water

Now, put (Eq1) into (Eq4)

volume of the solid=62.7 ml-48.4 ml

volume of the solid=14.3 ml

Step 2

put the values into the equation

density =\frac{mass\ of\ the\ object}{volume\ of\ the\ object} \\d=\frac{123.4 \ g}{14.3 \ ml} \\d=8.62937 \frac{g}{ml} \\ approximates\\d=8.63 g/ml

d=8.63 g/ml

in fact, answer b is not wrong since

1 ml=1 cm^{3}

Have a good day

Calculate annually compounded interest
Hunter-Best [27]

Answer:

$2,851.80

Step-by-step explanation:

Lets use the compound interest formula to solve:

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance</em>

<em>r = interest rate (decimal)</em>

<em>n = number of times compounded annually</em>

<em>t = time</em>

First, change 1.1% into a decimal:

1.1% -> \frac{1.1}{100} -> 0.011

Next, plug the values into the equation:

A=2,700(1+\frac{0.011}{1})^{1(5)}

A=2,851.80

She will have $2,851.80 after 5 years.

viva [34]

Step-by-step explanation:

First we need to find out what they all 3 equal, with multiplication.

5×5=25

10×5=50

20×5=100

In each of these problems, the answer is multiplying itself by 2 in order to get to the next answer. So this is how they are related
