Answer:

Mr. Rina will need 7 boxes.

Step-by-step explanation:

Important information:

He has 7 glass figures and he will use 1 box per glass figure.

So, you need to do 7 divided by 1 because he will ship each package with 1 glass figure. 7 glass figures divided by 1 box is 1 box per glass figure.

Jerome solved the equation below by graphing.

riadik2000 [5.3K]

Jerome rewrote the logarithms as

$\log_2x=\dfrac{\log x}{\log2}$

$\log_2(x-2)]=\dfrac{\log(x-2)}{\log 2}$

which eliminates C and D.

Solve the equation:

$\log_2x+\log_2(x-2)=\log_2x(x-2)=3\implies 2^{\log_2x(x-2)}=2^3\implies x(x-2)=8$

$\implies x^2-2x-8=(x-4)(x+2)=0\implies x=4\text{ or }x=-2$

$\log_b(-2)$ is undefined for any base $b$ (where the logarithm is real-valued), so we omit that solution.

This makes B the answer.

The standard kilogram (fig. 1.1a) is a platinum–iridium cylinder 39.0 mm in height and 39.0 mm in diameter. what is the density

ra1l [238]

The volume of a cylinder is calculated as pi*h*d^2/4, so in this case, V = pi*(39 mm)(39 mm)^2 / 4 = 46,589 mm^3. Dividing the mass of 1 kg by the volume of 46,589 mm^3 gives a value of 2.1464 x 10^-5 kg/mm^3. Usually, density values are given in kg/m^3, so we can convert by multiplying by 1x10^9, which gives a value of 21,464 kg/m^3.

Eli, Freda and Geoff were given £800 to share in the ratio of their ages.

algol13

First, we are going to find the sum of their age. To do that we are going to add the age of Eli, the age Freda, and the age of Geoff:
 $9+13+18=40$
The combined age of Eli, Freda, and Geoff is 40, so the denominator of each ratio will be 40.

Next, we are going to multiply the ratio between the age of the person and their combined age by £800:
For Eli: $\frac{9}{40} *800=180$
For Freda: $\frac{13}{40} *800=260$
For Geoff: $\frac{18}{40} *800=360$

We can conclude that Eli will get £180, Freda will get £260, and Geoff will get £360.
