A prism with a square base has a height of 15cm and a volume of 735cm3. Find the length of each edge of the base.

denis-greek [22]

Answer:

The length of each edge of the base is 7cm.

Step-by-step explanation:

The volume of a prism with square base is given by:

$V = l^{2}h$

In which l is the length of each edge of the base and h is the height.

A prism with a square base has a height of 15cm and a volume of 735cm3.

This means that $V = 735, h = 15$

$V = l^{2}h$

$735 = 15l^{2}$

$l^{2} = \frac{735}{15}$

$l^{2} = 49$

$l = \pm \sqrt{49}$

Length is a positive measure. So

$l = 7$

Volume in cm³, so the length of each edge is in cm.

The length of each edge of the base is 7cm.

Help me with this question pleasee

Liono4ka [1.6K]

Answer:

√23 = a

Step-by-step explanation:

/ab/²= /ac/²+/bc/² (Pythagoras theorem)

12² = a² +11²

144 = a² + 121

144 - 121 = a²

23 = a²

√23 = a

The function d(t) =300,000t represents the distance (in kilometers) that light travels in t seconds

3241004551 [841]

We were given the distance, d as a function of time, t.

$d(t)=300,000t$ .

To find $d(15)$ , we put $t=15$ , in to

$d(t)=300,000t$

This implies that,

$d(15)=300,000(15)$

$d(15)=4,500,000$

This means that in 15 seconds light covers a distance of 4,500,000 kilometers

m_a_m_a [10]

Answer:

Step-by-step explanation:

-10,20,-40,80,...

common ratio=20/-10=-2

it is a geometric sequence.

15,-5,-25,-45

common difference=-5-15=-20

it is an arithmetic sequence.

Plzz help steps if possible if not its ok j=i just need to pass this class

Answer:

$\text{(B) }\cos 40^{\circ}=\frac{x}{60}$

Step-by-step explanation:

In any triangle, the cosine/cos of an angle is equal to its adjacent side divided by the hypotenuse (longest side) of the triangle. (a/h)

The angle marked 40 degrees has an adjacent side of $x$ and the hypotenuse of the triangle is 60.

Therefore, we have the equation:

$\boxed{\cos 40^{\circ}=\frac{x}{60}}$
