1) Volume = L × W × H = 8 × 3 × 5 = 120 m³

2) Volume = s³ = 17³ = 17 × 17 × 17 = 4913 cm³

3) Volume = s³ = 30³ = 30 × 30 × 30 = 27000 cm³

4) Volume = L × W × H = 13 × 5 × 7 = 455 cm³

5) Volume = s³ = 15³ = 15 × 15 × 15 = 3375 cm³

Formula's applied:

(a) Volume of rectangle: Length × Width × Height

(b) Volume of Cube: (side)³

Write an equation of the line with the given slope and y-intercept:

romanna [79]

Answer: C

Step-by-step explanation: Since we know both the slope and the y-intercept we can plug them into Slope-Intercept form. Slope-Intercept form is y=mx+b

Since m = 2 and b = -3/4 all we have to do is replace both m and b in the form and that would be the answer. y = 2x-3/4

Vector v has magnitude5 units, w has magnitude 3, and the acute angle between them is 45°.

givi [52]

Answer:

25 units

Step-by-step explanation:

No matter the direction of the vector, if we multiply the vector v by -5v, the magnitude can be calculated as follows:

$|-5*V|$

Due to properties of absolute value:

$|-5*V|=5*|V|=5*(5units) = 25 units$

A coach purchases 47 hats for his players and their families at a total cost of $302. The cost of a small hat is $5.50. A medium

frosja888 [35]

Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of small hat purchased, y represent the number of medium hat purchased and z represent the number of large hat purchased.

Since a total of 47 hats where purchased, hence:

x + y + z = 47 (1)

Also, he spent a total of $302, hence:

5.5x + 6y + 7z = 302 (2)

He purchases three times as many medium hats as small hats, hence:

y = 3x

-x + 3y = 0 (3)

Represent equations 1, 2 and 3 in matrix form gives:

$\left[\begin{array}{ccc}1&1&1\\5.5&6&7\\-3&1&0\end{array}\right] \left[\begin{array}{c}x\\y\\z\end{array}\right] = \left[\begin{array}{c}47\\302\\0\end{array}\right] \\\\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}1&1&1\\5.5&6&7\\-3&1&0\end{array}\right] ^{-1} \left[\begin{array}{c}47\\302\\0\end{array}\right] \\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] = \left[\begin{array}{c}6\\18\\23\end{array}\right]$

Therefore he purchases 6 small hats, 18 medium hats and 23 large hats
