Answer: 639

Step-by-step explanation:

Multiple

Answer:

3 1/4 hours

Step-by-step explanation:

1 hour + 1/4 hour + 3/4 hours = 2 hours

3/4 hour + 2/4 hour = 1 1/4 hours

2 hours + 1 1/4 hours = 3 1/4 hours

Answer:

The equation for the speed of the train is: 162 = 3x

I think the speed of the train is 54 miles per hour

Step-by-step explanation:

We know that:

y = distance in miles

x = speed of train (miles/hour)

t = time traveled from the departing station (hours)

The equation: y = xt is given, we can therefore substitute the give values:

y = xt or tx

162 = 3x (This would be the equation)

Now we can find x by diving 3 on both sides of "="

162/3 = x

54 = x (This would be the speed of train)

Hope this helps!

No, this comparison is not reasonable.

This is the comparison given,

[tex]2.5 = 2.05[/tex]

Now,

[tex]2.5 = 2.50[/tex]

We know that,

[tex]2 .50 > 2.05[/tex]

So,

[tex]2.50 ≠ 2.05 \\ •°• \: 2.5 ≠ 2.05[/tex]

⎇ Hence, the comparison is not reasonable.

Answer:

5.44444442889 or 5 [tex]\frac{4}{9}[/tex]

Step-by-step explanation:

Just multiply the 2 numbers together

Answer:

[tex]2\frac{1}{3}^{2}[/tex] or 49/9 inches squared

Step-by-step explanation:

you have a square if those lengths are correct, and the formula for the area of a square is Bh=A B=base length (side on bottom), h=height (vertical side), and A=area, so 2 1/3 * 2 1/3 or 2 1/3^2

if that doesnt make sense, message me and i will try to help you more

Answer:

Volume of a cylinder = πr²h

Answer:

192

Step-by-step explanation:

Volume of triangular prism = area of base * length

The base of the triangular prism is a triangle

The area of a triangle can be calculated by multiplying the base length by the height and dividing that by 2

The base has a base length of 4m and a height of 8m

So area of base = [tex]\frac{4*8}{2}[/tex]

4 * 8 = 32

32 / 2 = 16

So the area of the base is 16m²

The prism has a length of 12m and we have identified that the area of the base is 16 so volume = 12 * 16

12 * 16 = 192

So the volume of the triangular prism is 192m³

Answer:

192 m^3

Step-by-step explanation:

V = 1/2 * 4 * 8 *12

V = 1/2 * 384

V = 192

Answer:

The value of the line segment [tex]ED[/tex] is 36.

Step-by-step explanation:

The hypotenuse represents the longest side in the right triangle. In this case, FD represents the hypotenuse as it is a multiple of 13. Based on the trigonometric relations described in the statements, we get the following relationships by definition of cosines:

[tex]\cos D = \frac{ED}{FD}[/tex] (1)

[tex]\cos F = \frac{EF}{FD}[/tex] (2)

If we know that [tex]\cos D = \frac{12}{13}[/tex] and [tex]FD = 39[/tex], then the length of the line segment [tex]ED[/tex] is:

[tex]ED = FD\cdot \cos D[/tex]

[tex]ED = 39\cdot \left(\frac{12}{13} \right)[/tex]

[tex]ED = 36[/tex]

The value of the line segment [tex]ED[/tex] is 36.

Answer:

48pq².

Step-by-step explanation:

(4pq+3q)² - (4pq - 3q)²​

This is the difference of 2 squares so we can use the identity

a^2 - b^2 = (a - b)(a + b):

(4pq+3q)² - (4pq - 3q)²​

= (4pq + 3q - (4pq - 3q)(4pq + 3q + (4pq - 3q)

= (4pq + 3q - 4pq + 3q)(4pq + 3q + 4pq - 3q)

= 6q * 8pq

= 48pq².

Answer:

48pq²

Step-by-step explanation:

As we know,

(a + b)² = a² + 2ab + b²

and

(a – b)² = a² – 2ab + b²

So,

(4pq+3q)² - (4pq - 3q)²​

= [(4pq)² + 2 X 4pq² X 3q + (3q)²] – [(4pq)² -  2 X 4pq² X 3q + (3q)²]

= (16p²q² + 24pq²+ 9q²) – (16p²q² – 24pq²+ 9q²)

= 16p²q²+ 24pq²+ 9q² – 16p²q²+ 24pq² – 9q²

= 24pq² + 24pq²

= 48pq²

Answer:

120.8°

Step-by-step explanation:

the total angle sum is of 360 so we add and subtract

35.8+25.4+178= 239.2

360-239.2= 120.8

so the missing angle measure is 120.8°

Step-by-step explanation:

Answer:

5 apples cost = 150 /-

Step-by-step explanation:

Two apples cost = 60 /-

Then 1 apple cost = 60 ÷ 2

= 30

∴ 1 apple cost = 30 /-

Then 5 apples cost = 30 × 5

= 150

∴ 5 apples cost = 150 /-

Answer:

(9-57i)

Step-by-step explanation:

We need to find the product of the given complex number i.e.

(3-9i)(6-i)

It can be solved as follows :

(3-9i)(6-i) = 3(6) +3(-i) +(-9i)(6) + 9i(i)

= 18-3i-54i+9i²

We know that, i² = -1

So,

= 18-3i-54i+9(-1)

= 18-57i-9

= 9-57i

So, the product of the given complex number is (9-57i).
