Answer:

Dimensions of the First Rectangular Box = 4 m × 3 m

Dimensions of the Second Rectangular Box = 5 m × 3 m

→Mulch needs to be applied to these two rectangular boxes with a height of 10 cm, equivalent to 0.01 m, since 1 meter equals 100 cm.

Volume calculation for 3 cuboids with dimensions of 4m × 3m × 0.01 m

= 3 × Length × Width × Height

= 3 × 4m × 3m × 0.01 m

= 0.36 m³Volume calculation for 2 cuboids with dimensions of 5m × 3m × 0.01 m

= 2 × 5m × 3m × 0.01 m

= 0.30 m³

Total volume of mulch to be added to the rectangular boxes

= 0.36 m³ + 0.30 m³

= 0.66 m³

Peter is at a lumber yard. He gets 2 free boxes of nails for every 10 boards he buys. Write an expression for the number of boxe
AnnZ [9099]
A. The quantity of 10-boards that Peter purchases is equal to n divided by 10. Consequently, each of the 10-boxes will receive two boxes of nails. After purchasing n boards, the formula for the number of boxes of nails Peter will have will be,

N = (2)(n/10)

When simplified,

N = n/5

b. If the total number of boards is 90, then,

N2 = (90/10)(2)(100 nails/box)
N2 = 1800

Final Answer: 1800

Which is equivalent to RootIndex 3 StartRoot 8 EndRoot Superscript x?
Zina [9171]

To determine an equivalent for RootIndex 3 StartRoot 8 EndRoot Superscript x, we can proceed with =2^x

Detailed Explanation:

We aim to express RootIndex 3 StartRoot 8 EndRoot Superscript x in a different form.

In mathematical terms:

(\sqrt[3]{8})^x

To solve:

Notably, 8 can be broken down into 2 multiplied by itself three times = 2^3

and \sqrt[3]{x}=x^{\frac{1}{3}}

Using these principles:

=((2^3)^{\frac{1}{3}})^x

=(2^{\frac{3}{3}})^x\\

=2^x

Thus, as we find a solution to RootIndex 3 StartRoot 8 EndRoot Superscript x, it results in =2^x
