The volume of the figure is 9ft 15ft 15ft 15ft please help fast PLEASE!

Whitepunk [10]

Step-by-step explanation:

Formulas.

Square: $V = L \times W \times H$

Square Pyramid: $V = \frac13b^2h$

b = base.

Let's work on the square first.

Substitute the Length, Width, and Height of the square into the formula:

$V=15 \times15\times15$

Solve:

$V=15^{3} =3,375$

Let's work on the square pyramid.

Substitute 225 into the formula, and 9 (height):

$V=\frac{1}{3}(15)^2(9)$

Solve:

$V=\frac{1}{3}225(9)$

$V=\frac{1}{3}(2025)$

$V=675$

Add each volume:

$3,375+675=4,050 ft^{3}$

The total volume of the figure is $4,050 ft^{3}$ .

A 2956 kg car starts from rest at the top of a driveway of length 6 m that is sloped at 35◦ with the horizontal. An average fric

zepelin [54]

Answer:

7.41 m/s

Step-by-step explanation:

Force of a car inclined at an angle

F=mg Sin Θ where; m = 2956 kg , g = 9.8m/s² , Θ = 35⁰

F = 2956 x 9.8 x Sin 35 = 16615.82 N

Net force due to friction = 16615.82 - 3080 = 13535.82 N

To calculate acceleration; F= Ma

13535.82 = 2956 x a

a = 4.58 m/s²

From equation of motion

$V^{2} = V_{o} ^{2} + 2aS$

V² = 0 + (2 x 4.58 x 6)

V = $\sqrt{54.95}$

V = 7.41 m/s

If r || s and M<5 = 128, what’s is M<1?? A. 128 B. 59 C. 62 D. 64

Fudgin [204]

We have been given that r is parallel to s. Now, if we look at angle 5 and angle 1, we can see that they are corresponding angles on parallel lines. Corresponding angles are ALWAYS equal, so therefore, your answer is 128 degrees; option A! :)

Hope this helped!
