Answer:

Step-by-step explanation:

move the +3 to the other side of the equation. -6x>18. divide 18 by -6. when you divide by a negative you have to flip the sign. x<-3

Im pretty sure it’s going to be a, because when you divide by the -6 you’re supposed to switch the sign

What is the volume of the following triangular pyramid?

Readme [11.4K]

Answer:

The volume of the triangular pyramid

V = 566.66 in³

Step-by-step explanation:

Step(i):-

The volume of the triangular pyramid

$= \frac{1}{3} X base area X height$

Base area = Area of the triangle

$A= \frac{1}{2} X base X height$

Given the base of the triangle (b) = 17in

Given Height of the triangle (h ) =10 in

$A= \frac{1}{2}( 17 ) (10) = 85$

The base area of the pyramid ( A) = 85 in²

Step(ii):-

Given the height of the pyramid (h) = 20in

The volume of the triangular pyramid

$= \frac{1}{3} X base area X height$

The volume of the triangular pyramid

= $= \frac{1}{3}( 85)(20) = 566.66$

Final answer:-

The volume of the triangular pyramid

V = 566.66 in³

Toben bought 5 1/2 pounds of chicken, which cost $3.50 per pound. What was the total cost of the chicken?

schepotkina [342]

The chicken cost $1.57 per pound.

You figure this out by dividing the total amount of chicken 5.5lbs (5 1/2) by the cost per pound.

5.5 / 3.50 = 1.57

Find the vol of this prism

polet [3.4K]

Answer:

V = 396 cm³

Step-by-step explanation:

the volume (V) of the prism is calculated as

V = Ah ( A is the area of the triangular face and h the height of prism )

A = $\frac{1}{2}$ bh ( b is base and h perpendicular height )

here b = 9, h = 8 , then

A = $\frac{1}{2}$ × 9 × 8 = 4.5 × 8 = 36 cm² , so

V = 36 × 11 = 396 cm³

I really need a quick answer to this question. Thank you!

egoroff_w [7]

Answer:

P U Q = {2, 3, 4, 5, 6, 7, 8, 9, 10}

P ∩ Q = {4, 6, 8}

Step-by-step explanation:

P = {2x, for 1 <= x <= 5}

P = {2, 4, 6, 8, 10}

Q = {x + 1, for 2 <= x <= 8}

Q = {3, 4, 5, 6, 7, 8, 9}

P U Q = {2, 3, 4, 5, 6, 7, 8, 9, 10}

P ∩ Q = {4, 6, 8}
