Answer:

61/125 or 0.488

Step-by-step explanation:

Total = 5×5×5 = 125

Numbers with no 4 = 4×4×4 = 64

Atleast one 4= 125-64 = 61

P(atleast one 4) = 61/125 or 0.488

The triangle on the grid will be translated two units left. On a coordinate plane, triangle A B C has points (negative 1, negati

nignag [31]

Answer:

Option B.

Step-by-step explanation:

The given vertices of triangle ABC are (-1, -1), (-1, -5) and (0.5, -5).

We need to find the coordinates of triangle when it is translated two units left.

So, the rule of translation is

$(x,y)\rightarrow (x-2,y)$

Using this rule, we get

$A(-1,-1)\rightarrow A'(-1-2,-1)=A'(-3,-1)$

$B(-1,-5)\rightarrow B'(-1-2,-5)=B'(-3,-5)$

$C(0.5,-5)\rightarrow C'(0.5-2,-5)=C'(-1.5,-5)$

The vertices of triangle A'B'C' are A'(-3,-1), B'(-3,-5) and C'(-1.5,-5).

Therefore, the correct option is B.

The mass of the Eiffel Tower is about 9.16 ⋅ 106 kilograms. The mass of the Golden Gate Bridge is 8.05 ⋅ 108 kilograms. Approxim

Answer:

$7.96 *10^8kg$

Step-by-step explanation:

Given

$Eiffel = 9.16 * 10^6\ kg$

$Golden\ Gate =8.05 * 10^8kg$

Required

Determine the difference in mass

This is calculated by subtracting the mass of Eiffel tower from the mass of Golden gate bridge

$Difference = Golden\ Gate - Eiffel$

$Difference = 8.05 * 10^8 - 9.16 * 10^6$

Express $10^8$ as $10^6 * 10^2$

$Difference = 8.05 * 10^2*10^6 - 9.16 * 10^6$

Express $10^2$ as $100$

$Difference = 8.05 * 100*10^6 - 9.16 * 10^6$

$Difference = 805 *10^6 - 9.16 * 10^6$

Factorize:

$Difference = (805- 9.16) * 10^6$

$Difference = 795.84 * 10^6$

Factorize the decimal number

$Difference = 7.9584 *10^2 * 10^6$

$Difference = 7.9584 *10^8$

Approximate:

$Difference = 7.96 *10^8$
