Jumlah panjang rusuk sebuah kubus adalah 84cm. luas permukaannya adalah.....
antoniya [11.8K]

Answer:

Total surface area of cube = 294 cm²

Step-by-step explanation:

Given:

Perimeter of cube = 84 cm

Find:

Total surface area of cube

Computation:

Perimeter of cube = 12 x side

84 = 12 x side

Side = 7 cm

Total surface area of cube = 6(a)²

Total surface area of cube = 6(7)²

Total surface area of cube = 294 cm²

Mr. Mole left his burrow and started digging his way down at a constant rate. Time (minutes) Altitude (meters) 666 -20.4−20.4min
Juli2301 [7.4K]

Answer:

-6 meters.

Step-by-step explanation:

We have been given Mr. Mole left his burrow and started digging his way down at a constant rate.

We are also given a table of data as:

Time (minutes)     Altitude (meters)

6                                   -20.4

9                                   -27.6

12                                   -34.8

First of all, we will find Mr. Mole's digging rate using slope formula and given information as:

m=\frac{y_2-y_1}{x_2-x_1}, where,

y_2-y_1 represents difference of two y-coordinates,

x_2-x_1 represents difference of two corresponding x-coordinates of y-coordinates.

Let (6,-20.4) be (x_1,y_1) and (9,-27.6) be (x_2,y_2).

m=\frac{-27.6-(-20.4)}{9-6}

m=\frac{-27.6+20.4}{3}

m=\frac{-7.2}{3}

m=-2.4

Now, we will use slope-intercept form of equation to find altitude of Mr. Mole's burrow.

y=mx+b, where,

m = Slope,

b = The initial value or the y-intercept.

Upon substituting m=-2.4 and coordinates of point (6,-20.4), we will get:

-20.4=-2.4(6)+b

-20.4=-14.4+b

-20.4+14.4=-14.4+14.4+b

-6=b

Since in our given case y-intercept represents the altitude of Mr. Mole's burrow, therefore, the altitude of Mr. Mole's burrow is -6 meters.

natali 33 [55]

Answer: 1/3 = 33.3% or 33 ⅓%

1/9 = 11.1%

2/9 = 22.2%

8/9 = 88.9%

Step-by-step explanation:

Divide the numerator by the denominator. Multiply the quotient by 100 to change the decimal to a percentage.

All of these are repeating decimals, so it may be required to keep at least one decimal place in the percentage, depending on how precise the calculation must be.
