Answer:
x√5 = x square root 5
Step-by-step explanation:
√35x^5 ÷ √7x^3 = √(35x^5 / 7x^3)
√(35x^5 / 7x^3) = √(5x^5 / x^3)
√(5x^5 / x^3) = √5x^(5-3) = √5x²
√5x² = x√5

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)

Two apples cost 60 cents. How much do five cost?
cost?
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 /-
Hope it is helpful....Explain why this comparison is either reasonable or not reasonable. 2.5 = 2.05
No, this comparison is not reasonable.
✐ Step-by-step explanation: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.
In right triangle DEF, it is known that Cos D = (12/13) and Cos F = (5/13). If FD = 39, then DE = ? Hint, draw the right triangle.
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.

a quadrilateral has angle measures of 35.8°, 25.4°, and 178°. What is the other angle measure?
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°

What is the product of the complex numbers below?
(3-9i)(6-i)
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).

PLZ HELP I BEGG. NEEDDD
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

(4pq+3q)² - (4pq - 3q)²
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
