Answer:

1 9/10 kilometers

Step-by-step explanation:

Given :

Distance 1 = 3/5 kilometers

Distance 2 = 1/2 kilometers

Total distance to be covered = 3 kilómeters

Distance already covered :

3/5 + 1/2

(6 + 5) / 10

= 11 / 10 kilometers

Distance left to be covered :

3 - 11/ 10

(30 - 11) / 10

= 19 / 10 kilometers

= 1 9/10 kilometers

A bookstore costs $90 a day to keep open, and spends $12 for each book it sells. the store charges $18 for each book it sells. I
denpristay [2]
Total Cost in a day is TC= 90 + 12n. Profit function is P=18n. And the revenue function is R = P-TC = 18n-12n-90 = 6n-90. In a day, bookstore must sell at least 15 books, because of 6n-90=0, in order to make profit.

These cones are similar. find the volume of the smaller cone. round to the nearest tenth.
Kamila [148]

Answer:

Volume of the smaller cone = 8.34 cm³

Step-by-step explanation:

"If two figures are similar, their dimensions will be proportional.

Following this rule,

Ratio of the dimensions of two cones = \frac{\text{Radius of the large cone}}{\text{Radius of the small cone}}

                                                               = \frac{r_2}{r_1}

                                                               = \frac{5}{2}

                                                               = 2.5

Similarly, "ratio of the volumes of two similar figures is cube of the dimensional ratio".

Ratio of the volumes = (ratio of the dimensions)³

\frac{V_1}{V_2}=(2.5)^3

\frac{131}{V_2}=15.625

V_2=\frac{131}{15.625}

    = 8.384 cm³  

    ≈ 8.4 cm³

Therefore, volume of the smaller cone is 8.4 cm³.

N which number does the digit 5 have a value that is ten times greater than the value of the digit 5 in the number 245,093?
OLEGan [10]

Answer:

53,901

Step-by-step explanation:

Here is the complete question :

In which number does the digit 5 have a value that is ten times greater than the value of the digit 5 in the number 245,093?

43,567

45,248

53,901

562,011

In the number 245,093 :

3 = units

9 = tens

0 = hundred

5 = thousand

4 = ten thousand

2 = hundred thousand

the value of 5 in the number is 5000. the number that would have a value that it 10 times greater than 5 in 245,093 must occupy the value  of ten thousand.

looking through the options, it is only in 53,901 that 5 occupies a value of ten thousand
