nlexa [21]

Answer:

448 cubes

Step-by-step explanation:

Volume of cubes fitted in the box will be equal to the cumulative volume of the cubes.

Since, volume of a cube = (Side)³

Side of the cube = $\frac{1}{2}$ inch

Therefore, volume of the cube = $(\frac{1}{2})^3=\frac{1}{8}$ inches

Volume of the storage box = 56 cubic inches

Since, number of cubes fitted in the storage box = $\frac{\text{Volume of the storage box}}{\text{Volume of one cube}}$

= $\frac{56}{\frac{1}{8}}$

= 56 × 8

= 448 cubes

Therefore, number of cubes fitted in the storage box = 448

How far is the point described by the ordered pair (4,5)<br>from the x axis?

weeeeeb [17]

Answer:

<h2>The point is 4 units away from the x-axis.</h2>

Step-by-step explanation:

The given ordered pair is (4, 5).

Remember, in a ordered pair, the first number is about the number of units used horizontally, and the second number is about the number of units used vertically.

So, this point is 4 units right side of the origin and 5 units upside of the origin.

Therefore, the point is 4 units away from the x-axis.

The kite is directly 35.707 yards high above Erika

Step-by-step explanation:

Given scenario forms a right triangle where the length of string is the hypotenuse and the distance between Mary and Erika is the base.

So

$H = 50\ yards\\B = 35\ yards$

We have to find the perpendicular

Using pythagoras theorem,

$H^2 = B^2 + P^2$

Putting the values

$(50)^2 = (35)^2 + P^2\\2500 = 1225 + P^2\\P^2 = 1275\\$

Taking square root on both sides

$\sqrt{P^2} = \sqrt{1275}\\P= 35.707$

Hence,

The kite is directly 35.707 yards high above Erika

The product of algebraic expression is $\rm 2d^3 - 7d^2- 103d + 36$ .

We have to determine

What is the product of d - 9 and 2d^2+11d-4?

<h3>How to find the product of two algebraic expressions?</h3>

The product of the algebraic expressions is also an algebraic expression. Lastly, simplify the algebraic expression by the fundamental operations of terms for combining the like terms.

Therefore,

The product of algebraic expression is;

$\rm = (d - 9) \times (2d^2 + 11d - 4)\\\\= d (2d^2 + 11d - 4)-9 (2d^2 + 11d - 4)\\\\= 2d^3+11d^2-4d-18d^2-99d+36\\\\=2d^3 - 7d^2- 103d + 36$

Hence, the product of algebraic expression is $\rm 2d^3 - 7d^2- 103d + 36$ .
